Concrete lining seepage-proofing and pressure-reducing structure of deeply-buried pressure hydraulic tunnel
The invention discloses an anti-seepage pressure-reducing structure for a concrete lining of a deeply-buried pressure hydraulic tunnel, which relates to the technical field of water conservancy and hydropower engineering and comprises a pressure hydraulic tunnel consolidation grouting layer and a concrete lining layer which are concentrically arranged. The concrete lining layer is stacked on the inner wall of the hydraulic tunnel consolidation grouting layer, a steel bar lining frame is arranged in the hydraulic tunnel consolidation grouting layer, and a plurality of anti-seepage pressure reducers are evenly arranged in the concrete lining layer along the circumference. The front-back distance of the movable limiting plate can be adjusted through the adjusting assembly, the reset spring is arranged between the movable limiting plate and the cross-shaped mounting frame, then the initial length and the pre-tightening force of the reset spring can be adjusted, different water stop seepage prevention and drainage pressure reduction requirements can be met, the structural design is ingenious, and use is more flexible; and in the adjusting process, the scraper can also clean soil accumulated on the outer filter plate, so that the outer filter plate is prevented from being blocked, and the drainage efficiency is improved.
本发明公开了一种深埋有压水工隧洞混凝土衬砌防渗减压结构，涉及水利水电工程技术领域，包括压水工隧洞固结灌浆层和混凝土衬砌层，压水工隧洞固结灌浆层和混凝土衬砌层同心设置，且混凝土衬砌层堆砌于压水工隧洞固结灌浆层的内壁，压水工隧洞固结灌浆层的内部设置有钢筋衬架，混凝土衬砌层内部沿圆周均匀设置有若干个防渗减压器；本发明可通过调节组件调整活动限位板的前后距离，复位弹簧又设置于活动限位板、十字形安装架之间，进而能调节复位弹簧的初始长度及预紧力大小，进而能适应不同的止水防渗和排水减压需求，结构设计巧妙，使用也更加灵活；在调节的过程中，刮片还能对外过滤板堆积的泥土进行清理，避免其出现堵塞，有利于提高排水效率。
