Construction method for preventing leakage of waterproof bottom plate of underground garage
The invention belongs to the technical field of waterproof design and construction of underground engineering, and particularly relates to a construction method for preventing leakage of a waterproof bottom plate of an underground garage. The method comprises the steps that a polyvinyl chloride foam rod with a fan-shaped section is arranged at the external corner position of a concrete cushion layer at the position where the thickness of a waterproof bottom plate changes suddenly; a waterproof layer is laid above the concrete cushion layer, and when the waterproof layer bypasses the polyvinyl chloride foam rod, a natural transition arc is formed; a sliding layer is laid on the waterproof layer, and a concrete protection layer is poured; and waterproof bottom plate steel bars are bound, and waterproof bottom plate concrete is poured. The national technical problems of waterproof bottom plate structure cracking and waterproof layer tearing and leakage are solved, the use function and structural durability of the waterproof bottom plate can be guaranteed, and the maintenance cost of waterproof engineering is greatly reduced. The method is suitable for waterproof design and construction of the waterproof bottom plate of the underground garage and waterproof design and construction of connection joints of post-cast strips, independent foundations, main building foundation rafts, retaining wall strip foundations and the like and the waterproof bottom plate.
本发明属于地下工程防水设计与施工技术领域，具体为一种预防地下车库防水底板渗漏施工方法。该方法包括在防水底板厚度突变处的混凝土垫层阳角位置，设置截面呈扇形的聚氯乙烯泡沫棒；在混凝土垫层上空铺防水层，在绕过聚氯乙烯泡沫棒时，形成顺势自然过渡弧形；在防水层上铺设滑动层，并浇筑混凝土保护层；绑扎防水底板钢筋，并浇筑防水底板混凝土等步骤。本发明解决了防水底板结构开裂、防水层撕裂与渗漏的全国性技术难题，可保障防水底板使用功能与结构耐久性，大幅度降低防水工程维护费用。适用于地下车库防水底板防水设计与施工及其后浇带、独立基础、主楼基础筏板、挡土墙条形基础等与防水底板连接节点的防水设计与施工。
