Sluice Gate IS:13349Sluice Gate as per IS CodeIS:13349 has flat surface on

the back side of frame, and donot have any extended part tobe embedded in the wall.

Hence civil work & time oferection is reducedconsiderably.

Application

IS: 13349 Standard, Page 1, Point 1.1.1These Sluice Gates are designed for either seatinghead or unseating head or both

IS: 3042 Standard, Page 4, Point 1.5This standard does not cover the types ofsluice gates where the operating forces tendto push the door away from the frame.

Seating Water HeadWhen the water pressure

tends to press the door /shutter on to the gate frame

then the type of water head

is called seating /

on-seating water head.

Unseating Water HeadWhen the water pressure tendsto push the door/shutter away

i.e. unseat from the gate framethen the type of water head iscalled unseating /off-seatingwater head.

Testing

Point 11: Shop Testing

11.1 All Sluice gates shall be subjected to thetests specified in 11.2, 11.3, 11.4, and 11.5for their conformity to the specified

requirements.

11.2 Seat Clearance Check: By 0.10 mmthick feeler gauge.

11.3 Smooth Movement Test

11.4 Shop Leakage Test by applyingUnseating Hydraulic Pressure

11.5 Hydrostatic Test to confirm bodysoundness by applying water pressure of1.5 times the unbalanced specified maximumoperating head on closed gate for a period of5 minutes.

IS: 3042 Standard, Page 10Point 8: Testing

8.1 After completion each sluice gate shall betested in the shop for smooth working of thecomponent parts including the operatinggear.

Comments: IS:3042 insist on only smoothworking of sluice gate and silent aboutleakage testing & body soundness.

In general IS:3042 gates are tested atatmospheric pressure for leakages only byborrowing leakage test parameter fromIS:13349 standard.

Due to spigot construction on the back side,IS:3042 gates can not fit on the test

bench and hence can not be tested forleakage at operating head as well as for bodysoundness.


6/6

When comparing IS:13349 Sluice Gates with IS:3042 Sluice Gates, we can seethat technically IS:13349 Gates are superior and they are designed for Seatingas well as unseating water head.

We can test the IS:13349 Sluice gates to confirm their suitability for designparameter, which can not be tested in case of IS:3042 gates.

Once the gate will be installed on site, nothing can bedone, even in case ofheavy leakage. The IS:3042 Gates can not be removed without damaging civilwork considerably.

The IS:13349 gates not only can be tested before installation itself to verify thesuitability in advance. These gates can be fitted as well as can be removed easilyby minimum damage i.e. by removing secondary grouting only.

As for as price are concerned, if we compare IS:3042 gate, which is wallmounted with the Wall mounted IS:13349 gate i.e. without wall thimble, it is a

proven fact that the IS:13349 gates are more cost effective, even in case ofinitial cost.
