Anti-seepage flexible step spillway and construction method thereof
The invention discloses an anti-seepage flexible step spillway and a construction method thereof, and relates to the technical field of hydraulic engineering. An original vertical slope stacked and built by geobags is adjusted and designed into a spillway inclined slope and spillway slope step combined structure, flowing water can be better guided, and more efficient flood overflow is achieved. Backfill in the CDASS geobags and forming backfill of a spillway inclined slope and a spillway slope step are binder soil mixed with lime, cement and soil materials, the anti-scouring performance and the anti-erosion performance of the soil material spillway and the stability of the slope and a discharge chute can be better guaranteed. Exposure parts of the whole spillway are subjected to anti-seepage treatment, erosion, seepage and scouring damage to the dam body from water flow are effectively prevented, and integrity and reliability of the dam body and the spillway are guaranteed. An originalsmooth type U-shaped nail is replaced with a T-shaped nail with a threaded structure, the anchoring effect is enhanced, the anti-seepage flexible step spillway is high in construction efficiency, andfew materials are used.
本发明公开了一种防渗柔性台阶溢洪道及其施工方法，涉及水利技术领域，本发明将原有的土工袋垒砌的直立式边坡，调整设计为溢洪道斜边坡和溢洪道边坡阶梯的组合结构，能够更好引导流水，更加高效的溢洪；CDASS土工袋内的回填土、溢洪道斜边坡和溢洪道边坡阶梯的成型回填土均为混合有石灰、水泥和土料的胶结土，能够更好的保证土料的溢洪道的抗冲刷性、抗侵蚀性和边坡与泄槽的稳定性；整个溢洪道的露出部分均进行了防渗处理，有效预防了水流对坝体的侵蚀、渗透和冲刷破坏，保证了坝体及溢洪道的完整性和可靠性；将原有光滑式U型钉更换为具有螺纹结构的T型钉，增加了锚固的效果，该防渗柔性台阶溢洪道施工效率高，使用材料少。
