High-speed rail closed layer expansion joint water stop structure
The invention provides a high-speed rail closed layer expansion joint water stop structure, an expansion joint is formed between a first structure and a second structure which are formed by concrete pouring, and the water stop structure comprises a water stop belt arranged at the bottom of the expansion joint; the water stop belt comprises a belt body, the two sides of the top face of the belt body are each provided with at least one water stop rib, the water stop ribs extend in the length direction of the expansion joint, and the water stop ribs on the two sides of the top face of the belt body are arranged at the bottom of the first structure and the bottom of the second structure respectively and poured into a whole with the first structure and the second structure. The portion, above the water stop belt, in the expansion joint is sequentially filled with a joint filling layer and a sealing layer from bottom to top. Compared with the prior art, the water stop structure has the advantages that the water stop ribs are arranged on the water stop belt and poured in the concrete structures on the two sides of the expansion joint, the combination area of the concrete structures and the water stop belt is increased, the water seepage path is changed and prolonged, rainwater is effectively prevented from permeating the roadbed, and the service long-term effect of the roadbed is improved.
本发明提供了一种高铁封闭层伸缩缝止水结构，伸缩缝形成在由混凝土浇筑成的第一结构和第二结构之间，止水结构包括设置在伸缩缝底部的止水带；止水带包括带体，带体顶面的两侧分别设置有至少一根止水肋条，止水肋条沿伸缩缝的长度方向延伸，带体顶面两侧的止水肋条分别设置在第一结构、第二结构的底部并与第一结构、第二结构浇筑为一体；止水带上方的伸缩缝内从下到上依次填充有填缝层和密封层。与现有技术相比，本发明提供的止水结构通过在止水带上设置止水肋条并浇筑在伸缩缝两侧的混凝土结构中，增加混凝土结构与止水带的结合面积，改变并延长渗水路径，有效阻止雨水渗透到路基，提高路基服役长效性。
