Underground prefabricated concrete comprehensive fire-fighting water pump house

The utility model relates to an underground prefabricated concrete comprehensive fire-fighting water pump house which comprises a concrete bottom plate, and the upper surface of the concrete bottom plate is fixedly connected with a concrete wall body. The connecting structure has the advantages that the two prefabricated box bodies are assembled through the connecting pins, the two box bodies can be connected more tightly through the sealing gaskets, the situation of water seepage at the connecting position is prevented, then the frame is placed at the connecting steel plates, the fixing columns on the frame are inserted into the fixing holes, then the threaded columns are rotated, and the box bodies can be fixed through the threaded columns. The fixing plates can be driven to move downwards through threaded transmission until the fixing columns on the fixing plates are inserted into the fixing holes, the two connecting steel plates can make close contact through the connecting components, then the two box bo
