Question

In the vertical Stoney spillway gate, the rollers are placed between the ______________

(a) gate and u/s groove guide

(b) gate and the d/s groove guide

(c) u/s and d/s groove guide

(d) attached to the gate and groove guides

This question was posed to me during an interview.

I need to ask this question from Types of Spillway Gates topic in division Spillways, Energy Dissipators and Spillway Gates of Irrigation Engineering

Answer 1

Correct choice is (b) gate and the d/s groove guide

The best explanation: A train of the roller is generally placed in between the gate and the d/s guide. These rollers may be placed independent of the gate and the guide thus eliminating the axle friction but rolls vertically between the two when the gate is moved.
