Underground engineering node waterproof structure construction method
The invention discloses an underground engineering node waterproof structure construction method. An underground engineering node waterproof structure comprises a concrete bottom plate and a concrete-filled plate, wherein the concrete bottom plate and the concrete-filled plate are poured and formed in a split mode, a step-type pouring belt area is arranged on the outer surface of the upper end ofthe concrete bottom plate, the concrete-filled plate is embedded in the step-type pouring belt area, an expansion water-stopping strip is arranged at the right-angle corner of the section of the step-type pouring belt area, and a concrete cushion layer is paved on each of the outer surfaces of the lower ends of the concrete bottom plate and the concrete-filled plate; and the construction method comprises the following steps that 1, concrete doped with a compound waterproof agent is adopted, and the step-type pouring belt area is reserved when the concrete bottom plate is poured. According to the method, the traditional method of a post-pouring strip water-stopping steel sheet is cancelled by adopting the concrete doped with the composite waterproof agent, so that the hidden danger of waterleakage at the node of a post-pouring strip of the bottom plate is reduced, the engineering construction period is shortened, and the engineering cost is reduced.
本发明公开了一种地下工程节点防水构造工法，所述地下工程节点防水构造包括混凝土底板与混凝土填充板，所述混凝土底板与混凝土填充板分体浇筑成型，所述混凝土底板的上端外表面设置有阶梯型浇带区域，且阶梯型浇带区域的内部嵌入混凝土填充板，所述阶梯型浇带区域截面直角处设置有膨胀止水条，所述混凝土底板与混凝土填充板的下端外表面铺设混凝土垫层，该施工方法步骤如下：步骤一：采用掺加复合防水剂的混凝土，在浇筑混凝土底板时预留阶梯型浇带区域。本发明采用掺加复合防水剂的混凝土取消了传统的后浇带止水钢板做法，既减少了底板后浇带节点处渗漏水的隐患，又节约了工程工期、降低了工程造价。
