[0002] A cofferdam refers to a temporary retaining structure built during the construction of permanent water conservancy facilities. Its function is to prevent water and soil from entering the construction site of the building so that drainage can be carried out within the cofferdam, foundation pits can be excavated, and buildings can be constructed. It is generally used in hydraulic structures. Except as part of a formal building, the cofferdam is generally dismantled after use.

[0003] When the prior art is used, during the construction process, the amount of water coming from upstream may exceed the design standard of the diversion facilities of this project. If the flood passes through the weir and causes the foundation pit to be submerged, after the flood, pumping and drainage equipment is used to drain the accumulated water in the foundation pit before the excavation of the foundation pit can be resumed. The existing cofferdam cannot achieve direct drainage, which affects the construction efficiency. Utility Model Content

[0010] Preferably, a ladder is provided inside the channel, a mounting groove is provided on the right side of the cofferdam, and a limiting frame is provided on the inner side of the upper end of the channel.

[0011] Preferably, a blocking grille is installed at the right end of the centralizing frame, and the blocking grille is located at the bottom of the flip plate.

[0012] Preferably, a drain pipe is installed on the left side of the combined pipe, and the drain pipe is located inside the cofferdam, and a driving motor is installed on the front side of the one-way valve.

[0013] Preferably, an adjusting motor is installed at the input end of the rotating seat, and the adjusting motor is located on the inner side of the mounting groove; a sealing disk is installed on the top of the adjusting motor, and the sealing disk is located on the inner side of the cofferdam.

[0014] Preferably, a positioning shaft is installed at the left end of the limiting frame, a combination cover is installed at the outer side of the positioning shaft, and an auxiliary handle is installed at the top of the combination cover.

[0015] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0016] 1. The utility model is equipped with a drainage component, and the water on one side of the cofferdam can be concentrated into the inside of the one-way valve through the combination pipe by using a concentration frame. The water flow can be discharged into the other side of the cofferdam by opening the one-way valve. The use of the drainage component can avoid the problem of not being able to drain water directly, which affects the construction efficiency.

[0017] 2. The utility model is equipped with an anti-clogging component. The existing drainage structure usually needs to use a grille to prevent clogging.
