Multilateral ribbed plate combined type water stop structure of underground diaphragm wall and construction method
The invention discloses a multilateral ribbed plate combined type water stop structure of an underground diaphragm wall. The multilateral ribbed plate combined type water stop structure is characterized in that the construction method comprises the following steps of (a) excavating a groove, and 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) hoisting a reinforcement cage; (f) hoisting a water stop device; g) lowering a guide pipe, and pouring concrete underwater; h) inserting H-shaped steel into the water stop device and pouring fine aggregate concrete; i) grooving the underground diaphragm wall on the other side of the joint; j) pulling out a joint pipe; and m) circulating the step d) and the step j) until construction of the whole underground diaphragm wall is completed, wherein the water stop device is of a multilateral ribbed plate stiff steel pipe concrete water stop structure. The safety coefficient and the water stop strength are improved.
本发明公开了一种地下连续墙多边加肋板组合式止水结构，a)沟槽开挖、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）吊放钢筋笼；f）吊放止水装置；g）下导管，水下浇筑混凝土；h）止水装置内插入H型钢，灌注细石混凝土；i)接缝另一侧地下连续墙成槽处理；j）拔出接头管；m）循环步骤d）~步骤j），直至完成整个地下连续墙的施工。其中，止水装置为多边加肋板劲性钢管混凝土止水结构。本发明提高了安全系数、以及止水强度。
