Reinforced concrete pipe

WATER TRANSMISSION GROUPWATER TRANSMISSION GROUP

Rugged and easy to install, trouble-freein performance, reinforced concrete pipeis manufactured for many applications.Storm drains, sanitary sewers, culverts,gravity water supply and irrigationsystems are all typical of the versatility,security and long-term economy of thismultipurpose pipe.Incorporating accurately placed steelreinforcement in its densely com-pacted concrete wall, reinforced

concrete pipe is designed to withstandsubstantial live and dead loads. It ismanufactured in diameters to suit allapplications and a wide range of D-loadrequirements.When looking for a strong, reliable pipeto serve your needs economically,consider these characteristics inherentin Ameron’s reinforced concrete pipe:Strength-Concrete and steel combinefor optimum security.Permanence-Concrete pipe has movedwater and wastes for centuries. No otherproduct exceeds its endurance records.Flow characteristics-The smooth,enduring interior wall providesexcellent flow characteristics.

Uniformity-Quality control and in-plant inspection assure uniformstandards of quality and performance.

Economy-Simplicity of installation,maintenance-free performance,corrosion resistance and longevityadd up to superior economy.

Specifications-Reinforced concretepipe is manufactured to meet therequirements of ASTM Designation:C76, “Reinforced Concrete Culvert,Storm Drain and Sewer Pipe,” andASTM Designation: C655, “ReinforcedConcrete D-Load Culvert, Storm Drainand Sewer Pipe.”

The table on this page indicates approximate deflections and offsets recommended for pipe sections installed by deflecting straight sections of pipe of various diameters.Pipe sections can be beveled at one or both ends to meet system design parameters. Sections beveled in this manner normally fit together on a 90-, 45- or 22.5-foot radius.1 Radius shown is minimum pipeline curve radius obtainable with straight 8' long pipe pulled (deflected) off centerline; the minimum radius for 4' long straight pipe is one-half of the value shown. Shorts (4' lengths) and beveled pipe may require substantially longer lead times than straight 8' long pipe.

D-load requirements for ordinary bedding

Design criteriaGeneral-D-load values given inthe table indicate greater accuracythan warranted in field installation;thus, when specifying, pipe shouldbe classified in 50-D increments;for example, 800-D, 850-D.Bedding-The above table is basedon installations with ordinarybedding’ and should not be used forother conditions, except as noted.D-loads given in the table are basedon a load factor of 1.50. For classesof bedding with load factors otherthan 1.50, the corrected dead loadmay be obtained by multiplying thetable’s dead load by

1.50 and dividing by the desired deadload factor.Backfill2-Based on Marston’s curvefor saturated topsoil, when Ku’=0.150,the table is conservative for sands,gravels and cohesionless materials.The D-load should be recomputed forclay backfills, when Ku’ < 0.150, usingthe correct coefficient. The table hasbeen computed using materials with aunit weight of 110 pounds per cubicfoot. For materials having a unit weightother than 110 pounds per cubic foot,the correct dead load can becalculated by multiplying the dead loadshown in the table by the desired unitweight and dividing by 110.

Trench width-D-loads given in thetable are based on trench widths (attop of pipe) of pipe OD plus 16 inchesfor pipe diameters 33 inches or. less;and pipe OD plus 24 inches for pipediameters greater than 33 inches. PipeODs are based on wall thicknessesgiven in the dimensional data table forWall A pipe through 96-inch diameter,and on wall thicknesses given in tablefor large diameter pipe with 102- and108-inch diameters. Thicker walldesigns may require a slightly higherD-load classification.For earth covers of two to eight feet,the tabulated dead load D-loadsapproach the maximum loads that

occur at the transition trench width.The difference in dead load for widertrench widths or the projectingconduit condition may be a smallvalue and the pipe may safelywithstand the increase. Forassurance it will be necessary to re-compute the D-loads for anyinstallation change at anydepth of cover.

Safety factor-A safety factor of 1.0against the occurrence of the0.01-inch crack is assumed in thecalculations. If a factor different than1.0 is desired, corrected D-loads canbe obtained by multiplying loadsshown in the table by the desiredsafety factor.

Live loads-Live load distribution iscalculated from AASHTO HS20for truck loads3 For differentwheel loadings, correct live loadscan be obtained by multiplying liveloads shown in the table by thedesired maximum wheel load inkips and dividing by 16. This table islimited to AASHTO live loaddistributions(a square at backfilldepth, H, whose sides equal1.75 H) for single truck loadingwith impact factors basedon depth. A live load factor of1.50, recommended in IowaState College Bulletin 112by Spangler for ordinary beddingor better, is used. For covers

nine feet and greater, live loads areincluded in the indicated D-loads.
