Water plugging method under open caisson bottom sealing water leakage condition
The invention discloses a water plugging method under the open caisson bottom sealing water leakage condition, and relates to the technical field of open caisson bottom sealing water seepage plugging treatment. Comprising the steps that a water collection pit is reserved in the center of the open caisson, a water leakage point at the bottom of the open caisson is found out, pit positions are chiseled out at the water leakage point, water is drained to the water collection pit, graded broken stone is laid in a ditch, PVC floral tubes are buried in the ditch, prefabricated concrete cover plates are arranged on the top face of the ditch and the side close to the water collection pit, the PVC floral tubes penetrate through the cover plates at the ends of the ditch, and water is pumped out through a water pump. A formwork is erected in the sump, graded broken stone is laid at the bottom, secondary bottom sealing concrete is poured, a cover plate is provided with a pre-buried steel sleeve with a water stop ring, a flange is arranged at the upper end, and a water pump continuously pumps water in the sump. And after secondary bottom sealing is completed and pouring is conducted, follow-up open caisson bottom plate construction is conducted, the water collecting pit is poured tightly when bottom plate concrete is poured, and a rubber water stop gasket and a blind plate are arranged at the end of the steel sleeve and embedded into the bottom plate concrete. The problem of sand gushing after bottom sealing of the open caisson is solved, and leaked water at the bottom sealing position is discharged in time.
本发明公开了一种沉井封底渗漏水情况下的堵水方法，涉及沉井封底渗水封堵处理技术领域。包括在沉井中心处留置集水坑，找出沉井底部渗漏水点，漏水点处凿出坑位，引流至集水坑，在水沟内铺设级配碎石，埋设PVC花管，在水沟顶面和靠集水坑侧设置预制混凝土盖板，PVC花管穿过水沟端部盖板，安装水泵将水抽出；在集水坑支设模板，底部铺设级配碎石，浇筑二次封底混凝土，盖板具有预埋带止水环的钢套管，上端设置法兰，水泵在集水坑内不断抽水。二次封底完成浇筑后，后续沉井底板施工，浇筑底板混凝土时将集水坑灌实，钢套管端部设置橡胶止水垫片和盲板，将其埋入底板混凝土内。本发明解决了沉井封底后涌砂问题、及时排出封底处渗漏水问题。
