Ground drainage structure for constructional engineering

The utility model relates to the technical field of constructional engineering, and discloses a ground drainage structure used in constructional engineering, which comprises a connecting pipeline, one end of the connecting pipeline is provided with a bump, the front surface of the bump is movably connected with a hinge shaft, and the outer wall of the hinge shaft is movably connected with a cover plate. A first water leakage groove is formed in the top of the cover plate, a plug pin is movably connected to the front face of the cover plate, and a handle is movably connected to the outer wall of the plug pin. According to the ground drainage structure used in the constructional engineering, through the hanging ring arranged at the bottom of the cover plate and the storage box hung through the hanging ring, building raw material residues in water can be effectively blocked and collected in the drainage process; when the ground drainage structure is used, the situation that building raw material residues flow to
