Water stop structure adapting to large deformation of concrete face rockfill dam joint
The invention discloses a water stop structure adapting to large deformation of a concrete face rockfill dam joint, which comprises a surface layer water stop formed by combining a coating type flexible water stop and an anchoring rubber plate, a middle layer water stop formed by using 15 full-wave corrugated belts and a bottom water stop formed by using a three-nose water stop copper sheet, and an SR-2 plastic filler is adopted to support a three-layer water stop structure. The water stop structure can adapt to large deformation of a joint, the fifteen full-wave corrugated water stop belts and the three-nose copper sheet are high in water stop stretching capacity, and the situation that the water stop structure is pulled and damaged, and consequently the anti-seepage function of the panel fails is avoided. The water stop structure can adapt to the high water seepage pressure environment, the surface modified epoxy coating is good in sealing performance, the GBW expansion plastic material plate is arranged at the contact position of the bottom three-nose copper sheet water stop and the concrete panel, and the GBW expansion plastic material plate is matched with SR-2 plastic filler to jointly prevent seepage water from invading the panel. The water stop structure is safe and reliable, and the design of the surface coating, the expansion bolt and the bottom copper sheet water stop embedded panel jointly ensures that the structure is not damaged by freezing, corrosion, extrusion, falling and the like.
本发明公开了一种适应混凝土面板堆石坝接缝大变形的止水结构，包括使用涂覆型柔性止水与锚固橡胶板结合的表层止水、使用15个全波波纹带的中层止水和使用三鼻子止水铜片的底部止水，并采用SR‑2塑性填料支撑三层止水结构。该止水结构能适应接缝大变形，15个全波波纹止水带与三鼻子铜片止水拉伸能力强，避免止水结构受拉破坏而使面板防渗功能失效。该止水结构能适应高渗水压力环境，表面改性环氧涂层密封性良好，底部三鼻子铜片止水与混凝土面板接触处设置了GBW膨胀塑性料板，配合SR‑2塑性填料共同阻止渗水入侵面板。该止水结构安全可靠，表面涂层、膨胀螺栓和底部铜片止水嵌入面板的设计共同保证结构不受冰冻、腐蚀、挤压、脱落等破坏。
