Earth rock cofferdam structure suitable for convex riverbed and construction method of earth rock cofferdam structure
The invention discloses an earth rock cofferdam structure suitable for a convex riverbed and a construction method thereof.The earth rock cofferdam structure comprises a natural riverbed, the natural riverbed is the convex riverbed protruding upwards, and the upstream side and the downstream side of the natural riverbed are filled with cofferdam lower rock-fill layers respectively; the natural riverbed and the top of the cofferdam lower rock-fill layer are jointly filled with a cofferdam middle rock-fill layer; the cofferdam lower rock-fill layer and the cofferdam middle rock-fill layer jointly form a rock-fill structure; an upstream anti-seepage cushion layer, an upstream anti-seepage layer and an upstream protection slope are sequentially arranged on the upstream side of the rock-fill structure from inside to outside; a downstream anti-seepage cushion layer, a downstream anti-seepage layer and a downstream slope protection layer are sequentially arranged on the downstream side of the rock-fill structure from inside to outside. The earth rock cofferdam structure is composed of a rock filling structure formed by a manual filling area and a natural riverbed, cofferdam filling materials are effectively reduced, riverbed steps can create favorable conditions for construction of other parts, the construction efficiency can be improved, resource integration is carried out according to local conditions, and investment is saved.
一种适用于凸型河床的土石围堰结构及其施工方法，该土石围堰结构包括天然河床，天然河床为向上凸起的凸型河床，在天然河床的上游侧、下游侧分别填筑有围堰下部堆石层，在天然河床以及围堰下部堆石层的顶部共同填筑有围堰中部堆石层；围堰下部堆石层和围堰中部堆石层共同形成堆石结构；在堆石结构的上游侧由内至外依次设置有上游防渗垫层、上游防渗层、以及上游护坡；在堆石结构的下游侧由内至外依次设置有下游防渗垫层、下游防渗层、以及下游护坡。该土石围堰结构由人工填筑区形成的堆石结构和天然河床组成，有效减少了围堰填筑用料，且河床台阶可为其他部位施工创造有利条件，这不仅可提高施工效率，还因地制宜地进行了资源整合，节省投资。
