Construction method of earth rock cofferdam with two anti-seepage structures
The invention relates to the technical field of earth rock cofferdams, and discloses a construction method of an earth rock cofferdam with two anti-seepage structures, which comprises the following steps: 1) surveying and setting out, determining a construction area, removing sundries and arranging a filter strip; (2) a plurality of intercepting ditches are arranged on the mountain, and ditch water outlets of the intercepting ditches are communicated to a reservoir; two cofferdam-crossing box culverts are arranged, and box culvert water outlets of the cofferdam-crossing box culverts are communicated to a reservoir; (3) a first-stage cofferdam is constructed in a layered filling mode, and the first-stage cofferdam is provided with a lower upstream face; (4) a plurality of Larsen plates are inserted into the first-stage cofferdam, the multiple Larsen plates are sequentially arranged in the crossing direction of the first-stage cofferdam, and a lower anti-seepage structure is formed; (5) a second-stage cofferdam is filled in a layered mode; (6) a geomembrane layer is laid, a soil containing bag provided with a soil body is arranged on the geomembrane layer, and the geomembrane layer is compacted on the upper upstream face through the soil containing bag; the geomembrane layer forms an upper anti-seepage structure, and the first-stage cofferdam and the second-stage cofferdam form an earth rock cofferdam.
本发明涉及土石围堰的技术领域，公开了带有两道防渗结构的土石围堰的施工方法，包括1)、测量放线，确定施工区域，清除杂物，布置过滤带；2)、在山体上布置多道截流沟，截流沟的沟排水口连通至水库布置；布置两道跨围堰箱涵，跨围堰箱涵的箱涵排水口连通至水库；3)、分层填筑施工一期围堰，一期围堰具有下部迎水面；4)、在一期围堰中插入多个拉森板，多个拉森板沿着一期围堰的横跨方向依序排布，形成下部防渗结构；5)、分层填筑二期围堰；6)、铺设土工膜层，在土工膜层上布置装置有土体的装土袋，装土袋将土工膜层压实在上部迎水面上；土工膜层形成上部防渗结构，一期围堰及二期围堰形成土石围堰。
