WANG JING / QIAN YINMIN / ZHOU YANG / LI JUNJIE

The invention discloses a civil engineering expansion joint waterproof structure, and belongs to the technical field of waterproof structures. The civil engineering expansion joint waterproof structure comprises a first block body, a second block body and a rain guide structure, the first block body is fixed to one side wall of an expansion joint, and a first slope is provided with a plurality of first sliding grooves; the second block body is fixed to the other side wall of the expansion joint, a plurality of drainage grooves are formed in a second inclined face, a supporting beam is formed between every two adjacent drainage grooves, and the supporting beams correspond to the first sliding grooves in a one-to-one mode; one end of a first plate body is fixed to the side, close to the expansion joint, of the first block body, the lower part of the other end of the first plate body is overlapped with one end of a second plate body, and the other end of the second plate body is fixed to the side, close to the expansion joint, of the second block body. According to the civil engineering expansion joint waterproof structure, it is guaranteed that objects cannot fall into the expansion joint, the two side walls of the expansion joint are reinforced, the first plate body and the second plate body are overlapped, and the problems that rainwater flows backwards into the expansion joint, and water is accumulated in the expansion joint are solved.

本发明公开了一种土木工程伸缩缝防水结构，属于防水结构技术领域。该土木工程伸缩缝防水结构包括：第一块体，固定于伸缩缝的一个侧壁上，第一斜面设有多个第一滑槽；第二块体，固定于伸缩缝的另一个侧壁上，第二斜面设有多个排水槽，相邻两个排水槽之间构成一个支撑梁，各支撑梁和各第一滑槽一一对应；导雨结构，第一板体的一端固定在第一块体上靠近伸缩缝的一侧，第一板体的另一端下方交叠第二板体的一端，第二板体的另一端固定在第二块体上靠近伸缩缝的一侧。本土木工程伸缩缝防水结构保证物体不会掉落进伸缩缝并对伸缩缝两侧壁进行了加固，第一板体和第二板体交叠，避免了雨水倒灌进伸缩缝和导致伸缩缝内积水的问题。
