Joint water stop structure for differential settlement of dam body of concrete faced rockfill dam
According to the joint water stop structure for differential settlement of the dam body of the face plate dam, in the structure, a bottom W-shaped water stop copper sheet is arranged at the bottom of a bottom vertical joint to form a third water stop, a middle-buried water stop belt is arranged in the middle of the bottom vertical joint to form a second water stop belt, and the two ends of the middle-buried water stop belt are connected into a first face plate and a second face plate; a bottom vertical joint between the rubber rod and the bottom W-shaped water stop copper sheet is filled with the pitch-soaked pine board to form a totally-closed water stop structure, and the caulking water stop filler layer is arranged on the top plane joint and the middle Y-shaped joint and located on the rubber rod to form a closed plastic water stop belt. The seepage-proofing surface cover plate covers the caulking water stop packing layer and extends to the top surface of the first panel and the top surface of the second panel, the obtuse angle steel is arranged on the seepage-proofing surface cover plate and exerts lateral constraint on the arc surface section of the seepage-proofing surface cover plate, and the flexible seepage-proofing coating forms a totally-closed flexible seepage-proofing layer. The structure can effectively and reliably stop water under the condition of large deformation.
一种用于面板坝坝体不均匀沉降的接缝止水结构，结构中，底部W型止水铜片设置于底部垂直接缝的底部以构成第三道止水，中埋式止水带设置于底部垂直接缝中部以构成第二道止水，中埋式止水带的两端连接于第一面板中与第二面板中；浸沥青松木板填充于橡胶棒与底部W型止水铜片之间的底部垂直接缝中以构成全封闭止水结构，嵌缝止水填料层设置于顶部平面接缝和中间Y型接缝且位于橡胶棒上以构成封闭性塑性止水带，防渗表面盖板盖设于嵌缝止水填料层且延伸到第一面板和第二面板的顶表面，钝角角钢设于防渗表面盖板上且对防渗表面盖板圆弧面段施加侧向约束，柔性防渗涂层形成全封闭的柔性防渗层。本结构大变形条件下有效可靠止水。
