The utility model belongs to the technical field of waterproof of lower room structures, and particularly relates to a waterproof and anti-leakage structure of a
basement connection node. In order to solve the problems that complex
water seepage paths are difficult to
resist, the maintenance cost is increased due to inconvenience in disassembly and maintenance and a waterproof layer is easy to crack due to insufficient deformation coordination of a rigid
assembly and a wall body in the existing single-layer waterproof or permanent fixed installation design, the following scheme is provided: the waterproof structure comprises an existing wall body and a newly-built wall body; a multi-stage
water seepage blocking path is formed through the inner waterproof layer and the
water stop steel plate, and even if a single layer is damaged, underground
water pressure can still be effectively resisted; quick disassembly and
assembly are achieved through threaded connection and a clamping structure, wall damage is avoided, and the maintenance cost is remarkably reduced; the flexible coiled material and the sealing rubber strip absorb
structural deformation displacement, the fixing block
embedment design limits displacement of the waterproof belt, long-term stability under dynamic loads is ensured, and the technical problems that a traditional waterproof layer cracks, is difficult to maintain and poor in adaptability are comprehensively solved.
