Construction method for repairing water-rich stratum concrete sump inrush water leakage
The invention provides a water-rich stratum concrete sump inrush water leakage repairing construction method, and belongs to the technical field of water leakage in water-rich areas, and the method comprises the following steps: S1, pumping water to clean a sump to find a water leakage point, and investigating water burst reasons and conditions in detail; s2, determining a repair construction method according to the on-site water burst pressure; s3, opening holes in the inrush point positions of the foundation pit, and installing a water pipe valve for drainage; s4, waterproof plugging is conducted around the drainage point of the water pipe valve; s5, concrete is temporarily poured in the waterproof plugging range, and the horizontal sealing layer resists the water bearing pressure and the subsequent reverse grouting pressure; s6, reverse grouting is conducted through the drainage pipe, and the grouting quality is controlled in cooperation with an infrared thermal imager; s7, the water leakage condition after repairing is detected, and a waterproof layer is constructed on the downstream face of the foundation pit; the construction technology is simple, the problem is effectively solved, good impermeability is achieved after repairing is completed, and the strength of an original structural member is guaranteed. The water collecting pit is prevented from losing normal use functions, and in addition, adverse effects on the surrounding environment are prevented.
本发明专利提出的一种富水地层混凝土集水坑突涌漏水修补施工方法，属于富水地区漏水技术领域，包括S1、抽水清理集水坑查找漏水点，详细勘察涌水原因和情况；S2、根据现场涌水压力大小，并确定修补施工方法；S3、基坑突涌点位开孔，安装水管阀门引流；S4、水管阀门引流点周围进行防水封堵；S5、防水封堵范围临时浇筑混凝土，水平封层抵抗水承压力及后续反向注浆压力；S6、通过引流管反向注浆，配合红外线热成像仪把控注浆质量；S7、检测修补后渗漏水情况，基坑背水面施工防水层；本发明解决了其施工工艺简单解决问题有效，修补完成后具有良好的抗渗性且保证原结构构件强度。避免集水坑失去其正常使用功能，另外防止对周边环境造成不良影响。
