Water leakage maintenance method for point switch pit structure
According to the water leakage maintenance method for the point machine pit structure, a water channeling layer and the bottom of a foundation pit can be comprehensively blocked, the construction period is short, and the influence on normal operation of a locomotive is small. The method comprises the following steps: (1) grouting, filling and tamping a void layer: drilling a grouting hole, penetrating through a ballast bed layer to the void layer, burying a grouting pipe, preparing slurry, then grouting, removing the grouting pipe, and blocking the grouting hole; and (2) filling and bonding a gap between the ballast bed structure and the base structure: drilling a grouting hole, penetrating through the ballast bed layer to a void layer, embedding a grouting needle, preparing slurry, filling, removing the grouting needle, and blocking the grouting hole.
一种转辙机坑结构的渗漏水维修方法，其能够全面封堵窜水层和基坑底部，并且施工周期短，对机车的正常运行影响小。其包括以下步骤：(1)对脱空层灌浆、填充、夯实：钻注浆孔，穿透道床层至脱空层，埋设注浆管，配制浆液后灌注，然后撤除注浆管，封堵注浆孔眼；(2)对道床结构和基底结构之间的间隙进行灌注粘接：钻注浆孔，穿透道床层至脱空层，埋设注浆针头，配制浆液后灌注，然后撤除注浆针头，封堵注浆孔眼。
