Seamless expansion joint structure for bridge joint treatment and construction process of seamless expansion joint structure
The invention discloses a seamless expansion joint structure for bridge joint treatment and a construction process of the seamless expansion joint structure, and relates to the technical field of bridge joint treatment. The seamless expansion joint structure comprises an elastic expansion assembly, a waterproof layer and a straddle steel plate; an expansion joint is formed between an original mainline box girder and a broadened box girder, and a containing groove is formed between pavement structures at the tops of the two box girders; the straddle steel plate is horizontally erected above the expansion joint and is connected and fixed through a mounting assembly; the elastic expansion assembly is laid in a segmented mode in the length direction of the expansion joint, the elastic expansion assembly comprises a plurality of layers of elastic expansion bodies connected with one another, and the elastic expansion bodies are fixedly bonded in the containing groove through waterproof bonding glue; and the waterproof layer is located on the upper surface of the last layer of elastic expansion body. The problems that an existing seamless expansion joint structure easily causes water leakage of the bridge deck and the repair time is longer after the existing seamless expansion joint structure is damaged are solved, and the effects that cracking of the expansion joint structure is reduced, so that water leakage of the bridge deck is reduced, and the repairing time after damage is short are achieved.
本发明公开了一种用于桥梁接缝处理的无缝伸缩缝结构及其施工工艺，其涉及桥梁接缝处理技术领域。其中无缝伸缩缝结构包括弹性伸缩组件、防水层和骑缝钢板，原主线箱梁与拓宽箱梁之间形成伸缩缝，两个箱梁顶部的路面结构之间开设容纳槽；骑缝钢板水平架设于伸缩缝上方，并通过安装组件连接固定；弹性伸缩组件沿伸缩缝长度方向分段铺设，弹性伸缩组件包括若干层相互连接的弹性伸缩体，弹性伸缩体通过防水结合胶固定粘接于容纳槽内；防水层位于最后一层弹性伸缩体上表面。本发明解决了现有的无缝伸缩缝结构容易导致桥面漏水，且损坏后修复时间较长的问题，具有减少伸缩缝结构的开裂，从而减少桥面漏水，且损坏后修复时间较短的效果。
