Blocking structure for construction process of HDPE geomembrane composite anti-seepage wall
The invention discloses a blocking structure for the construction process of a HDPE geomembrane composite anti-seepage wall. The blocking structure is arranged in an anti-seepage groove. The anti-seepage groove comprises a constructed segment and a non-constructed segment. The blocking structure is used for preventing backfilling materials of the constructed segment from flowing to the non-constructed segment. The blocking structure comprises a segmented pipe, a buffering pipe and a blocking film, wherein the segmented pipe is arranged between the constructed segment and the non-constructed segment in the vertical direction, and the starting end of the composite anti-seepage wall is located between the segmented pipe and the non-constructed segment; the buffering pipe is arranged in the construction segment in the vertical direction; and the blocking film comprises a fixed end and a free end, the fixed end is connected to the outer wall of the segmented pipe, and the free end is bent between the segmented pipe and the buffering pipe and then extends between the composite anti-seepage wall and the buffering pipe. The blocking structure effectively prevents the backfilling materialson one side of the construction side in the anti-seepage groove from flowing to one side which is not constructed, the procedure of cleaning backfilling materials on the side which is not constructedis reduced, the construction period is shortened, an acceleration groove segment is stable, and the construction safety is improved.
本发明公开了一种HDPE土工膜复合防渗墙施工过程中的封挡结构，封挡结构设置在防渗沟槽内，防渗沟槽包括施工段和未施工段，封挡结构用于阻止施工段的回填料流向未施工段，封挡结构包括：分段管，分段管沿竖直方向设于施工段与未施工段之间，且复合防渗墙的起始端位于分段管与未施工段之间；缓冲管，缓冲管沿竖直方向设于施工段内；阻挡膜，包括固定端和自由端，固定端连接于分段管的外壁，自由端在分段管与缓冲管之间弯折后延伸至复合防渗墙与缓冲管之间。封挡结构有效防止防渗沟槽中施工一侧的回填料流向未施工的一侧，减少了清理未施工一侧回填料的工序，缩短了施工周期，加速槽段稳定，提高施工安全。
