[0002] A water conservancy project is an engineering facility for regulating and controlling water resources. When building the dam of a water conservancy project, it is necessary to drain the water in the foundation holes through a water supply and drainage device, and then build with steel bars and concrete so that the foundation can be fixedly supported for water storage control management.

An outlet hopper 8 is arranged at one end of the a drain pipe 71 away from the a water suction frame 1, and the outlet hopper 8 is arranged obliquely, and the outlet hopper 8 can guide the discharged gravel. A baffle 14 is arranged on the b water suction frame 4, the lower end of the baffle 14 is located at the top end of the b drain pipe 72, and the baffle 14 can prevent water flow from entering the mounting frame 5 from the connection between the b rotating column 11 and the b water suction frame 4, resulting in damage to the driving mechanism 6.
