Leaking stoppage device for deepwater cofferdam bottom sealing concrete leakage and leaking stoppage method thereof
The invention discloses a plugging device and a plugging method for sealing concrete leakage of a deepwater cofferdam. The deep water cofferdam bottom sealing concrete leakage stoppage device comprises a drainage groove formed in a bottom sealing concrete leakage point, a first drainage pipe embedded in the drainage groove, a water collection pit communicated with the first drainage pipe and formed in bottom sealing concrete and a second drainage pipe communicated with the first drainage pipe and vertically arranged, and a water pump is installed in the water collection pit. The top of the second drainage pipe protrudes out of the top end face of the bearing platform, the drainage groove is further filled with single graded broken stone, and the single graded broken stone is arranged around the first drainage pipe. According to the plugging device for sealing concrete leakage of the deepwater cofferdam, the problem of sealing concrete leakage of the steel cofferdam can be effectively solved, and meanwhile the plugging device is easy to construct and low in cost.
本发明公开了一种深水围堰封底砼渗漏的堵漏装置及其堵漏方法。本深水围堰封底砼渗漏的堵漏装置包括开设于封底砼渗漏点处的引流槽、埋设于引流槽中的第一排水管、与第一排水管连通且开设于封底砼上的集水坑、以及与第一排水管连通且竖向设置的第二排水管，集水坑内安装有水泵，第二排水管的顶部凸伸于承台顶端面外，引流槽中还填充有单一级配碎石，单一级配碎石围绕第一排水管周围设置。本发明提出的深水围堰封底砼渗漏的堵漏装置，能有效解决钢围堰的封底砼渗漏问题，同时其施工简单且成本低。
