Expansion joint flat pressing structure and method of hydraulic structure
The invention provides an expansion joint flat pressing structure and method of a hydraulic structure, and belongs to the technical field of water conservancy and hydropower engineering. The flat pressing structure comprises a hydraulic structure and a flat pressing assembly. The hydraulic structure is built between two banks of a river body and provided with a plurality of expansion joints. The flat pressing assembly is arranged in the expansion joint and comprises a pipe network and a caulking material. A water outlet and a water inlet of the pipe network communicate with the upstream, facing the river body, of the hydraulic structure. Through holes are fully distributed in the pipe wall of the pipe network, and the caulking material is filled between the expansion joints of the pipe network. According to the expansion joint flat pressing structure, the water pressure in the expansion joint between the expansion joints of the hydraulic structure can reach hydrostatic pressure, the pressure change of the water pressure in the expansion joint is kept synchronous with the water pressure change of the upstream or the downstream, it is ensured that the actual application of the hydraulic structure is consistent with the design working condition, and stability and safety are improved.
本发明提供了一种水工建筑物的伸缩缝平压结构和平压方法，属于水利水电工程技术领域。该平压结构包括水工建筑物和平压组件。水工建筑物建造于河体的两岸之间，水工建筑物具有多个伸缩缝。平压组件设置于伸缩缝中，平压组件包括管网和嵌缝材料。管网的出水口和入水口均与水工建筑物面向河体上游连通。管网的管壁上布满通孔，嵌缝材料填充于管网伸缩缝之间。该伸缩缝平压结构能够使水工建筑物的伸缩缝间的缝内水压达到静水压力，且缝内水压的压力变化与上游或者下游的水压变化保持同步，确保对水工建筑物的实际应用与设计工况一致，提高稳定性与安全性。
