FOREWORD

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized bythe Hydraulic Gates and Valves Sectional Committee, had been approved by the River ValleyDivision Council.

Different types of hydraulic gates and hoists, working on the same or different principles andmechanism are presently in use for controlled release or water through spillways, sluices, in­takes, regulators, ducts, tunnels, etc. Right selection of gat es and their hoisting arrangementis very important to ensure safety of the structure and effective control. A designer has toplan a gate and its hoisting arrangement together. Separate planning of gates or hoists,sometimes results in unsatisfactory installation. Though the choice fC'r the gates and hoistsdepends on several factors, primarily safety, ease in operation as well as maintenance andeconomy are the governing requirements in the same order. The objective of this standard isnot to give concluding recommendations but to highlight different factors, which would largelyeffect the choice of gates and hoists and would help in selection of the same.

CRITERIA FORCHOICE OF GATES AND HOISTS

2.3 Based on Operational Requirements:

Such as radial gates.Sector gates, hingedleaf gates, fallingshutters.

b) Non-regula­ting gate

a) Service gates To be used for regulation( main gate) and routine operation

such as main gate forregulation of flowthrough spillway sluices,outlets, etc.

b) Emergency : To close the opening inclosure gates flowing water condition

in case of emergencysuch as emergencypenstock gate.

c) Maintenance : Bulkhead gate, emer-gate gency gate, stoplogs

which are used for main­tenance.

d) Construction Required to shut offgates opening during construc-

tion or to finally closethe opening afterconstruction such asconstruction sluicegates, diversion tunnelgates, etc.

a) Regulating : Operated under partialgates openings. Generally the

main regulating gatesare the service gates.Gates not suitable aswell as not intended foroperation under partialgate openings.

1 SCOPE1.1 This standard lays down the criteria Corchoice of common gates and hoists.

2 CLASSIFICA1ION OF GATES
