Combined cofferdam for lattice bin stone cage construction of strong quicksand stratum of linear river channel and construction method of combined cofferdam
The invention discloses a combined cofferdam for lattice bin stone cage construction of a strong quicksand stratum of a linear river channel and a construction method of the combined cofferdam. The combined cofferdam for lattice bin stone cage construction of the strong quicksand stratum of the linear river channel comprises a combined frame body which is of an up-down penetrating structure, a bedding layer laid on the inner wall of the combined frame body, a lattice bin stone net cage arranged on the inner wall of the bedding layer and a plurality of stone layers arranged in the lattice bin stone net cage in a filling mode, wherein the stone layers are sequentially laid along the lattice bin stone net cage from bottom to top. The combined cofferdam for lattice bin stone cage construction of the strong quicksand stratum of the linear river channel is reliable in structure, rapid to assemble and good in use performance, the constructed combined frame body can be recycled, and the cost is reduced; the construction method of the combined cofferdam is convenient to operate, construction is safe and reliable, the construction period is shortened, the construction efficiency is improved, the cofferdam effect is good, and the situation that quicksand enters a foundation pit is effectively avoided.
本发明公开了一种线性河道的强流沙地层格宾石笼施工的组合围堰及其施工方法，包括上下呈贯穿结构的组合框体、铺设于组合框体内壁的铺垫层、设置在铺垫层内壁上的格宾网笼以及填充在格宾网笼内部的多层石料层，且石料层沿格宾网笼由下至上依次铺设；该组合围堰结构可靠，组装迅速，使用性能好，施工后的组合框体能够循环使用，降低了成本，该施工方法操作便捷，施工安全可靠，缩短施工周期，提高了施工效率，且围堰效果好，有效的避免了流砂进入基坑。
