由于上下游水深较深，该水闸宜选用较大的单宽流量，所以可降低闸底板高程，

Because the upstream and downstream water depths are deep, the sluice should use a larger single-wide flow, so the sluice floor elevation can be reduced to make the sluice floor elevation the same as the river bottom.

Because the water depth of the upper and lower reaches is deep, the sluice should choose a larger single wide flow, so that the gate floor elevation can be reduced, so that the gate bottom plate elevation and the river bottom is the same height.

Due to the deep water depth of the upstream and downstream, the sluice should choose a large single width discharge, so the elevation of the sluice floor can be reduced, so that the elevation of the sluice floor is the same as the river bottom.<br>
