Description

Structure direct connection type pump system {Pump system installed directly in concrete structure}

The present invention relates to a pump system configured by installing a submersible pump directly on a concrete structure rather than a sluice gate. It relates to a structure-directly connected pump system in which a forced discharge part that operates to discharge water from the upstream downstream is directly configured in a concrete structure to function as a pump gate without a sluice gate.

The pump gate is a drainage system in which the submersible pump is installed on the sluice gate and the sluice gate and the submersible pump are integrated.

More specifically, the pump gate is configured to have a submersible pump installed in the sluice gate configured to open and close the water channel while moving up and down by the hoist.

In such a pump gate, when the sluice gate is raised by the hoist and the water channel is opened, the internal water inside the sluice gate is naturally drained to the outside of the sluice gate through the open water channel. In this case, the sluice gate is lowered and the waterway is closed.

On the other hand, the pump gate can drain the internal water out of the sluice gate through the operation of the submersible pump even when the water channel is closed by descending the sluice gate. Damage caused by floods can be prevented more effectively.

In order to construct such a pump gate, not only the use of a lot of materials and equipment such as a sluice gate and a hoist is required, but also the construction process of installing the pump gate in a concrete structure is difficult and complicated, which consumes a lot of time and money.
