Anti-seepage structure for pipeline penetrating through curtain and construction method
The invention discloses a curtain penetrating pipeline anti-seepage structure and a construction method, and relates to the technical field of pipeline anti-seepage, the curtain penetrating pipeline anti-seepage structure comprises a grouting gallery, a grouting hole is formed in the bottom surface of the grouting gallery, the grouting hole intersects with an excavation tunnel, a tunnel lining is arranged on the surface of the excavation tunnel, and a flexible anti-seepage structure is arranged at the junction of the excavation tunnel and the grouting hole. The flexible anti-seepage structure is arranged at the junction of the excavated tunnel and the grouting hole, the two water stop belts and the two supporting rods are arranged, meanwhile, the filler is filled, connection between the tunnel and an original grouting curtain is more flexible, original rigid connection is changed into flexible connection, the flexible anti-seepage structure can flexibly adapt to uncoordinated deformation of the tunnel and the original grouting curtain, and the anti-seepage effect is good. And through the later reinforcing seepage prevention of the PVC backfill grouting pipe and the synergistic effect of the flexible seepage prevention structure and the PVC backfill grouting pipe, drilling and water pressing tests are not needed during seepage prevention operation, the seepage prevention effect is better guaranteed, meanwhile, the construction period is shortened, and the construction cost is reduced.
本发明公开一种穿帷幕管道防渗结构及施工方法，涉及管道防渗技术领域，包括：包括灌浆廊道，灌浆廊道底面设置有灌浆孔，灌浆孔与开挖隧洞相交，在开挖隧洞表面设置隧洞衬砌，开挖隧洞与灌浆孔交界处布置柔性防渗结构。通过在开挖隧洞与灌浆孔交界处布置柔性防渗结构，设置2条止水带，2个支撑棒，同时充填填充物，使得隧洞和原灌浆帷幕之间的连接更灵活，由原来的刚性连接变为柔性连接，柔性防渗结构能灵活适应隧洞和原灌浆帷幕的不协调变形，更好地保证了防渗效果以及通过PVC回填灌浆管的后期补强防渗，柔性防渗结构和PVC回填灌浆管协同作用，实现在进行防渗操作时无需钻孔和压水试验，更好地保证了防渗效果的同时还降低了施工工期和施工费用。
