Cofferdam structure and construction method thereof
The invention provides a cofferdam structure. The cofferdam structure comprises a front-row pile and a rear-row pile, wherein the bottom of the front-row pile and the bottom of the rear-row pile are inserted into a soil layer, piles in the front-row pile and piles in the rear-row pile all extend in the Z-axis direction and are arranged at intervals in the Y-axis direction, cofferdam is arranged between the front-row pile and the rear-row pile, the cofferdam comprises a plurality of X-direction connecting beams and a plurality of Y-direction connecting beams which are connected with each other,the X-direction connecting beams are arranged between the two adjacent piles in the front-row pile or between the two adjacent piles in the rear-row pile, and the Y-direction connecting beams are arranged on one side of the front-row pile or one side of the rear-row pile; a first blocking part is arranged on the side, close to the rear-row pile, of the front-row pile, a second blocking part is arranged on the side, close to the front-row pile, of the rear-row pile, and a space between the first blocking part and the second blocking part is filled with a soil stone material. The invention further provides a construction method of the cofferdam structure. The cofferdam structure has the following beneficial effects that the water blocking safety requirement of the cofferdam structure against the high water head can be met, and meanwhile, the manufacturing cost is reduced, and the construction cost is reduced; and in addition, the filling material is convenient to obtain, and the projectconstruction duration requirement can be met.
本发明提供了一种围堰结构，包括底部插入土层中的前排桩和后排桩，前排桩和后排桩中的桩均沿Z轴方向延伸、沿Y轴方向间隔排布，两者之间设有围檩，围檩包括多个相互连接的X向连接梁和Y向连接梁，X向连接梁设置在前排桩或后排桩中相邻的两根桩之间，Y向连接梁设置在前排桩或后排桩的一侧；前排桩靠近后排桩的一侧设有第一阻挡部，后排桩靠近前排桩的一侧设有第二阻挡部，第一阻挡部和第二阻挡部之间填筑有土石料。本发明还提供了一种围堰结构的施工方法。本发明的围堰结构具有以下有益效果：既能够满足围堰结构抵御高水头的挡水安全要求，同时降低了造价，降低了施工成本。此外填筑材料取材方便，可以满足工程工期要求。
