ABSTRACT:
A pumping system for gates wherein a sluice body liftably received in the guide grooves formed in the side walls of a water channel mounts a plurality of pumps in parallel with each other, the suction ports and the discharge ports of the pumps being located in the upstream and downstream sides, and a debris collecting device is provided in the water channel upstream the pumps. The suction ports of the pumps are opened towards the bottom of the water channel at a given height, and the debris collecting device is so constructed that it can be liftable over the level of the water channel. At the time of a natural drainage, the sluice body and the debris collection device are lifted to allow free flow of the water through the water channel, while at the time of a forced drainage the sluice body and the debris collecting device are lowered so that debris, etc. flowing in the upstream side of the water channel are first collected by the debris collecting device, and the water is then pumped from the upstream to the downstream sides by the suction thereof through the pit.
