In the building construction, before the earthwork of the underground water level above the excavation surface of the foundation pit is excavated, drainage ditches for dewatering or drainage pipelines for dewatering are required to be built, or the underground water is drained to a filtering tank, a sedimentation tank and a clarification tank and then to a municipal pipe network. And after the underground water level is reduced to be below 0.5 m below the base, earth excavation can be carried out. The drainage ditches or intercepting ditches arranged around the foundation pit are generally constructed in a brick-building mode, and plastering treatment is carried out on the inner side, the outer side and the bottom of the ditch. The method has the defects that the perimeter of the ditch is longer, the ditch bottom substrate is settled, mortar is shrunk and the like, so that the ditch is easy to crack, the water leakage phenomenon is caused, the side slope of the foundation pit is washed due to the water leakage, and the side slope is easy to be unstable and collapse, so that accidents are caused.
