Special-shaped ribbed plate combined type water stop structure of underground diaphragm wall and construction method
The invention discloses a special-shaped ribbed plate combined type water stop structure of an underground diaphragm wall. The special-shaped ribbed plate combined type water stop structure comprises a multilateral pipe pile, and ribbed plates are symmetrically arranged on the two sides of the multilateral pipe pile relative to a center joint; H-shaped steel is arranged in a cavity defined by the multilateral pipe piles; fine aggregate concrete is filled between a cavity defined by the multilateral pipe piles and the H-shaped steel; at least three rib plates are arranged on each of the two sides of the center joint of the multilateral pipe pile; the multilateral pipe piles are connected with the H-shaped steel piles, and the H-shaped steel piles are arranged on the side of an underground water seepage layer; the construction method comprises the following steps of a) building a guide wall; b) grooving the underground diaphragm wall on one side of a joint; c) removing sludge and residues at the bottom of the groove; d) hoisting a joint pipe; e) setting an H-shaped steel pile; f) setting a special-shaped multilateral pipe pile; g) secondary cleaning of the groove bottom; h) hoisting a reinforcement cage; i) putting down a guide pipe; j) setting the H-shaped steel pile, and pouring concrete; k) grooving the underground continuous wall on the other side of the joint; m) drawing out the joint pipe; and n) circulating. The safety coefficient and the water stop strength are improved.
本发明公开了一种地下连续墙异型加肋板组合式止水结构，包括多边管桩，多边管桩两侧关于中缝对称设置有肋板；多边管桩围成的腔体内设有H型钢；多边管桩围成的腔体内与H型钢之间填充有细石混凝土；多边管桩中缝两侧的肋板均至少为三个；多边管桩与H型钢桩相连，H型钢桩设于地下水渗水层侧。施工方法为：a)修筑导墙；b）接缝一侧地下连续墙成槽处理；c)清除槽底淤泥以及残渣；d）吊放接头管；e）打设H型钢桩;f）打设异型多边管桩；g）二次清理槽底；h）吊放钢筋笼；i)下导管;j）打设H型钢桩，并灌注混凝土；k)接缝另一侧地下连续墙成槽处理；m）拔出接头管;n)循环。本发明提高了安全系数、以及止水强度。
