3 Usage instruction double slide-rail shoring DG PV krings

Occupational safety and general remarks according to DIN EN 13331-1/2

1. Lifting, handling, pulling, dragging

Handling should be carried out as close to the ground as possible.

Slings (chain type and thickness, load hooks) must be chosen to suit the weight being handled (e.g.trench box or slide rail).

To prevent the accidental detachment of the load during lifting, pulling or handling, only load hooks withsafety catches may be used.

Particularly when pulling loads, the pulling forces defined in section 7.4.16 in DIN EN 13331/1 must be observed.

The load must be slung in such a way that the shoring is in a horizontal position and swinging duringhandling is reduced to a minimum.

The shoring must be lowered onto level and firm ground.

It is prohibited to stand within the pivoting range of the excavator/crane and beneath suspended loads.

A load operator may only stand to the front left of the excavator, in constant eye contact with the machine operator.

It is always prohibited to stand within the danger zone.

Observe the industrial safety ordinance and the accident prevention regulations for lifting gear.

2. Measures to reduce hazards

The safety of vehicles and persons on site must be ensured with the aid of cones, warning tape orsafety staff specially deployed for this purpose.

The construction site should be sufficiently marked as such with the aid of warning signs, for instance.

The risk of instability as a consequence of wind loads when setting up the shoring on the edge of the trench must be considered.

The shoring should be secured against accidental impacts and set up in a sufficiently stable position (sufficient width and firm ground).

When handling, installing and removing shoring, watch out for overhead power cables.

On sloping or uneven ground, the shoring should be set up if possible at right angles to the slope.


From an intermediate piece length combination of 1.10 m, it is mandatory to mount the shoring horizontally.

3. Reasons for taking parts out of service and instructions for repair

Before use, all shoring components must be checked for theircorrect function.

Reasons for taking worn or damaged parts out of service include:

Missing parts, such as nuts, screws, posts, pins and

stabilizers.

Broken parts such as spindles, pins and spreader

systems in general.

If parts are severely deformed or misshapen or if there

are holes in panel bodies, for instance, the manufacturer

should be consulted in cases of doubt.

In all cases of doubt, always consult the manufacturer.

Faulty parts must be replaced or repaired.

Minor repairs can be carried out by the user, after consultation with the manufacturer.

Only original replacement parts from the manufacturer may be used.

There is no warranty on incorrectly performed repairs and the use of non-original parts.

The requirements of the industrial safety ordinance apply.

4. Procedure in the event of an accident

In the event of an accident, casualties must be given first aid immediately.

The scene of the accident must be cordoned off and left unchanged.

If the injured person is expected to be unfit for work, an accident insurance doctor must be consulted.

All accidents must be reported immediately to the superior or his deputy.

The accident must be entered in the accident record book.

The currently valid versions of the following documents apply:

Provisions of the Civil Engineering Committee of the Accident Insurance Institution

DIN 4124 "Baugruben und Gräben" (pits and trenches)

DIN EN 13331, Part 1: Product Specifications, Part 2: Assessment by Calculation or Test

General safety instructions and the relevant industrial safety ordinances

Our products bear the "Geprüfte Sicherheit" (GS) quality seal.

During installation, the instructions contained in the manufacturer's manual must be referred to and observed.

Identical to the EG PV single slide-rail system, the DG PV doublesliderail system meets the highest standards of economy and flexib-ility. The boogie car is available in rectangular and U-versions. Thissystem thus creates far greater working space than rival systems.The boogie cars are vertically displaced in accordance with themanufacturer’s structural loading specifications. This means theycan be fixed in the desired installation position for optimum loaddischarge. At the same time, the boogie car also ensures that theslide-rails are kept absolutely parallel.

When constructing in-situ concrete sewers, the boogie car can beraised right up as soon as the concrete base slab has set. This createsthe greatest possible working space, permitting the construction ofsewers up to 5.0 m high. To cater for larger trench widths, the systemcan be widened by inserting flanged extension bars.

Assembly instructions for the guide frame of double slide-rail shoring DG PV anddouble slide-rail shoring DG PV with piling frame KKP KD6 CPS

1. System overview of the guide frame

(1) Two slide rails DG PV

(2) Two roller units

(3) Two spacer bars

2. Fitting the slide

By using lifting gear and a suitable sling (GS-approved), slide a roller unit into each of the slide rails DG PV.

3. Pinning the slide

Secure the roller unit in the slide rail DG PV by inserting the pins (4) and (5) into the envisaged holes (see detail X) at the top and bottom of the rail, above and below the roller unit. After insertion the pin must be turned through 180°.

X



From an intermediate piece length combination of 1.10 m, it is mandatory to mount the shoring horizontally.

4. Fitting the spacer bars

The pre-assembled combinations of spacer bars (3) required for the desired trench width are aligned with the bolting plates of the roller units and bolted with the required number of bolts as per piece list. To facilitate alignment of the spacer bars during the next assembly step, the bolts are only loosely fastened.

5. Assembly of the complete guide frame

The slide rail DG PV prefitted with the roller units and spacer bars is pivoted over the second soldier so that the roller units and spacer bars can be bolted together.

After assembly, the guide frame is laid flat on the ground.

All screw joints must be tightened firmly.

For large trench widths, the complete guide frame should be assembled on its side. To this end, the two roller units inserted into the slide rails must be prefitted with spacer bars of about the same length. After preassembly, the two slide rails are laid side by side on the ground so that the spacer bars can be bolted together.

To create a shoring unit, two fully assembled guide frames are required. For each further shoring unit, an additional guide frame must beprovided.


Installation instructions for double slide-rail shoring DG PV

1. Placing the first guide frame

After measurement of the trench line, the initial layer of soil is excavated for the first shoring unit in accordance with the projectmanagement’s instructions.

Width: Required clear trench width + approx. 0.7 m

Length: Module length + approx. 0.5 m (or panel length + approx. 0.8 m)

Using lifting gear and a suitable sling (GS-approved), the firstguide frame is placed in the centre of the trench axis and at right angles to the trench line. The bottom end of the roller unit rests on the pin secured in the slide rail and its upward motion is limited by a pin in the guide frame (see assembly instructions). If necessary, the frame can be locked plumb (e.g. with the aid of a second setof lifting gear).

2. Inserting the base panels

The base panels are inserted with lifting gear from above into the slide rail profile. After insertion, the shoring panels are lowered to the bottom of the trench.

Before lowering the linear shoring frame, always remove the pin if it has been inserted to set a different vertical pipe clearance.


3. Aligning the shoring panels

The first shoring unit has to be precisely aligned so that the shoring runs parallel with the trench axis. It is important here thatthe horizontal clearance between the shoring panels is the same at both panel ends; and that the two diagonal axes of the shoring unit are the same length.

lichte Weite = Clear width Diagonale = Diagonal

4. Placing the second guide frame

The second frame is guided over the exposed guide profiles of the base panels and lowered to the bottom of the trench.

After placement, the shoring unit should again be aligned (as described in step 3) in order to facilitate the installation and removal of subsequent shoring units.

The cavity between the soil and shoring panel must be backfilled and compacted.

5. Lowering the shoring unit

Before the lowering process proper, the soil beneath the shoring panels is excavated in accordance with the project management’s instructions. The slide rails, shoring panels and roller units are pressed down in turn, with special use being made of protective rails.

The shoring components must be pressed and on no account struck or hammered.

When lowering the system, make absolutely sure that the roller units are positioned vertically to provide the required structuralstrength (pay attention to length of cantilever).

6. Inserting the outer top panels

B

T

Depending on the required trench depth, the outer top panels (T) are inserted in the outer rail guides when the outer base panels (B) have been lowered to the provisional trench bottom.

The base and top panels must be joined together with bolts (5) and spring pins (6).


7. Inserting the inner base panel

The inner base panel is guided into the inner guide rail, and lowered to the bottom of the trench. Trench excavation continues with the lowering of the inner base panel, guide frames and roller units.

When lowering the system, make absolutely sure that the roller units are positioned vertically to provide the required structuralstrength (pay attention to length of cantilever).

8. Inserting the inner top panel

In accordance with the instructions of step 6, further height adjustment of the wall of shoring can be achieved by inserting inner top panels (T).

The base and top panels must be joined together with bolts (5) and spring pins (6).


9. Installing the next shoring unit

The next shoring unit is installed as soon as the previous unit has been fully lowered to the bottom of the trench and the roller units are vertically positioned in order to provide the required structural strength and fixed. Installation is described in steps 1 to 8.Subsequent units are aligned with the precisely installed first unit. The clear trench width and length of diagonal (step 3) when inserting the shoring panels should be checked for each subsequent unit.

10. Pipe laying

Once the complete desired train of shoring has been fully lowered to the bottom of the trench, pipe laying can start.

The roller units must be vertically positioned and fixed with pins in order to provide the required structural strength.


Instructions for removing double slide-rail shoring DG PV

Removal, backfilling and compacting

At the end of pipe-laying work, the shoring is removed with layer-by-layer backfilling and compacting. To this end, the shoring is extracted step-by-step in accordance with the instructions of the project manager on site and with the expert's specifications and the backfilling material returned to the trench is compacted against the existing soil.

Slings must only be attached to the holes provided.

Support for base of soldier/cast-in-place concrete

1. Inserting the shoring

When laying pipes of large diameter or building cast-in-place concrete drains/sewers, additional support for the guide frames atthe base of the soldiers is often needed for reasons of stability. To this end, the shoring is initially installed in accordance with the installation instructions (see "Installation instructions for double slide-rail linear shoring DG PV", steps 1 to 9) and the bottom of the trench prepared in accordance with requirements. Any support for the base of the soldiers depends on the cal-culations of structural strength and takes the form of a spar of steel or reinforced concrete. In the case of cast-in-place concretedrains/sewers, the bed carrying the drain/sewer can be used as the support for the base of the soldier. The support for the base of the soldier should have a contactsurface sufficiently large for the soldier. Proof of structural strength should be provided for the load-bearing capacity of the support for the base of the soldier.


2. Creating support for the base of the soldier

When support for the base of the soldier has been provided, the roller unit can be raised to the maximum permitted vertical pipeclearance for completion of the cast-in-place concrete structure. In this position, the roller unit must be secured with chains or pins.

During raising, the roller unit must always be prevented from sliding out of the top of the soldier (for pin, see "Assembly instructions for the guide frame for double slide-rail shoring DG PV", step 3).

If the shoring is also to serve as formwork for a cast-in-placeconcrete structure, the open guides of the roller units in the slide rails must be sealed with sealing panels. In this way, a continuous smooth surface is created together with the KRU shoring panels. An intermediate layer (e.g. rigid foam panels, plastic sheeting) must always be inserted between the shoring and the cast-in-place wall in order to ensure smooth removal.

3. Removing the shoring unit

When the concrete walls have set, the shoring is removed in theway described in "Instructions for removing double slide-railshoring DG PV".


Installation instructions for double slide-rail shoring DG PV with piling frame KKP KD6 CPS

1. General remarks

For double slide-rail shoring DG PV with piling frame KKP KD6 CPS, sheet piles are guided in piling frame elements. To make allowancefor pipes/cables crossing the trench, particularly in densely built-up inner-city areas, openings can thus be flexibly provided in the supported and secured trench walls.

2. Placing the first guide frame

After measurement of the trench line, the initial layer of soil is excavated for the first shoring unit in accordance with the projectmanagement’s instructions.

Width: Required clear trench width + approx. 1.0 m

Length: Module length + approx. 0.5 m

Using lifting gear and a suitable sling (GS-approved), the firstguide frame is placed in the centre of the trench axis and at right angles to the trench line. The bottom end of the roller unit rests on the pin secured in the slide rail and its upward motion is limited by a pin in the guide frame (see "Assembly instructions for the guide frame of double slide-rail shoring DG PV"). If necessary, the frame can be locked plumb (e.g. with the aid of a second set of liftinggear).

3. Placing the piling frame element

The piling frame element is pivoted from above into the slide rail.

Before lowering the slide rail frame, always remove the bottom pin if it has been fitted to set a different vertical pipe clearance.


4. Aligning the piling frame element

The first shoring unit has to be precisely aligned so that theshoring runs parallel with the trench axis. It is important here thatthe horizontal clearance between the piling frame element is thesame at both ends; and that the two diagonal axes of the shoring unit are the same length.

5. Placing the second guide frame

Using lifting gear, the second frame is guided over the exposed guide profiles of the piling frame element and lowered to thebottom of the trench. On unstable soils in particular, chains must be used to prevent the piling frame elements from sinking.

After placement, the shoring unit should again be aligned (seestep 4) in order to facilitate the installation and removal of subsequent shoring units.

The cavity between the soil and piling frame element must bebackfilled and compacted.

6. Inserting the sheet piles and lowering the shoring unit

When the sheet piles have been inserted in the two opposite piling frame elements, further soil can be excavated beneath the sliderails and sheet piles in accordance with the instructions of project management on site. The sheet piles and slide rails are pushed or pressed down in turn. The shoring components must be pressed and on no account struck or hammered.

The piling frame elements must be fixed in position.

When lowering the system, make absolutely sure that the roller units are positioned vertically to provide the required structural strength (pay attention to length of cantilever).

7. Inserting Krings waling girders

After exposure of the pipe/cable crossing the trench, Krings waling girders must be attached on either side of the shoring in order to provide the required structural strength. One end of the waling girders is pushed into the open guide of a slide rail. The slide railat the other end of the waling girders must not be lowered to the bottom of the trench (see adjacent figure). Only at the next stage (step 8) is this pair of slide rails pushed via the guide profile of the waling girders resting on the bottom of the trench.

Fitting the waling girders reduces the cantilever length of the sheetpiles and prevents the sheet piles being inwardly deflected into thetrench.


8. Pressing the pair of slide rails and lowering the shoring

When the pair of slide rails has been lowered, both ends of the waling girders rest in the open guides of the slide rails. The sheet piles are now pressed down. Make sure that the waling girders and sheet piles are pressed tightly together. If the waling girders have to be lowered, they must be prevented from accidentally sliding out of the slide rails, e.g. with a chain.

9. Lowering to the final depth

With advance soil excavation in accordance with the instructions of the project management on site, the shoring unit is lowered to its final depth. Chains (GS-approved) are used to lock the walinggirders at the horizontal level demanded for reasons of stability. Here, again, the roller unit must be vertically positioned to providethe necessary structural strength (pay attention to length of cantilever).


10. Installing the next shoring unit

The next shoring unit is installed as soon as the preceding unit has been fully lowered to the bottom of the trench and the roller units are vertically positioned and fixed in order to provide therequired structural strength. Installation is carried in the manner described in steps 1 to 9. Subsequent units are aligned with the precisely installed first unit. The clear trench width and length of diagonal (step 4) should be checked for each subsequent unit when installing the piling frame elements.

11. Pipe laying

Once the complete desired train of shoring has been fully lowered to the bottom of the trench, pipe laying can start.

The roller units must be vertically positioned in order to provide the required structural strength and fixed with pins or chains.

For removal, see the instructions given in the "Instructions for removing double slide-rail linear shoring DG PV".


12. Installation example

There is no problem combining "double slide-rail shoring DG PV" with "double slide-rail shoring DG PV with piling frame KKP KD6 CPS".


KRINGS pit shoring consists of a small number of highly effectiveshoring components with which shoring solutions for practically anytype of pit can be realised – regardless of its size, depth or shape.Special corner slide-rails and the proven shoring panels form a self-contained, versatile system for securing shaft walls.

The slide-rail system pits can be used in many different ways, suchas for launch and reception pits for pipejacking and also for tank pits,manholes and construction pits as bored pile shoring, and other ex-cavation projects.

Installation instructions for double slide-rail corner shoring

1. General remarks

Double slide-rail corner shoring is a special shoring method for shaft structures as well as for trench shoring with combined trench-end units. If used for shaft shoring, special bracing systems can be omitted. All the forces are then discharged via the shoring panels. With the appropriate soldiers, it can take the form of single or double slide-rail shoring.

By using different panel lengths in pairs, it is possible to realize rectangular pits of various sizes.

2. Installing the base panels

After measurement of the pit, the initial layer of soil is excavated for the shaft to match the panel lengths used. The projectmanagement’s instructions and the relevant standards must beobserved.

The first shoring panel is lifted with lifting gear and a suitable sling (GS-approved) into the pit and fixed.

3. Installing the corner rail

By using a second set of lifting gear, the corner slide rail can now be slotted in from above.

4. Installing further elements

All further elements must be installed in the manner already described.

5. Aligning the shoring

So that the last wall of shoring can also be installed without difficulty, the shoring has to be properly aligned. To this end, it is important here that the horizontal clearance between the shoring panels is the same at both panel ends; and that the two diagonalaxes of the shoring unit are the same length.

6. Lowering the shoring

When the fourth base panel has been installed, the rectangularity of the shoring must again be checked. Then the cavity between the soil and shoring panel must be backfilled and compacted.

Before the lowering process proper, the soil beneath the shoring panels and slide rails is excavated in accordance with the projectmanagement’s instructions. The slide rails and shoring panels are pressed down in turn, with special use being made of pressure beams for the shoring panels.

The shoring components must be pressed and on no account struck or hammered.


7. Installing the inner base panels

The inner base panel is lowered to the bottom of the trench. Trench excavation continues with the lowering of the inner base panels and slide rails.

8. Example of a trench-end unit

There is no problem combining "double slide-rail shoring" with "double slide-rail corner shoring". This way it is possible to continuously shore pits and trenches.
