Optimization of Construction Technology for Off-wall Ditch of Metro Station
From the perspective of the current subway station construction,the water retaining sill from the wall ditch is often restricted by the construction of the upper side wall,so it is not suitable to be poured synchronously with the structural board.Water leakage from the wall ditch in the subway station is a common phenomenon,especially in the construction of the wall ditch,there are many reasons for the leakage from the wall ditch.This paper optimizes the design size of the water sill,chisel process,waterproof treatment and concrete mixing ratio.The results show that increasing the width of the water sill from the wall ditch,reducing its height,deepening the depth of the cut,increasing the waterproof of spray fast rubber asphalt,and reducing the size of concrete stone will greatly reduce the seepage point of the wall ditch.
