Water-swelling water-blocking wooden plug precipitation well composite well sealing device and method
The invention discloses a composite well sealing device and method for a dewatering well with a water-swelling water-blocking wooden plug, the composite well sealing device comprises the dewatering well arranged in a foundation soil layer, the water-blocking wooden plug is inserted in the dewatering well, one or more annular water-blocking strips are fixed on the water-blocking wooden plug in the height direction, the water-blocking strips are flush with the side wall of the water-blocking wooden plug, and the water-blocking wooden plug is arranged in the dewatering well. The top of the water-blocking wooden plug is flush with a well mouth of the dewatering well, a socket steel pipe extending upwards is arranged on the upper surface of the water-blocking wooden plug, and micro-expansion impervious concrete is poured on the periphery of the socket steel pipe. And a foundation bottom plate and a foundation bottom plate cushion layer which is located below the foundation bottom plate and is in lap joint with a foundation soil layer are arranged on the periphery of the micro-expansion impervious concrete. According to the construction method, the closing quality of the precipitation well can be effectively improved, the hidden danger of leakage is reduced, the well closing effect is good, the construction cost is saved, and the quality and economic benefits are outstanding.
本发明公开一种遇水膨胀阻水木塞降水井复合封井装置及方法，包括开设在地基土层内的降水井，所述降水井内插接有阻水木塞，阻水木塞沿高度方向上固定有一个或一个以上的环形状止水条，止水条与阻水木塞的侧壁相齐平，且阻水木塞的顶部与降水井的井口齐平，所述阻水木塞的上表面设置有向上延伸的承插钢管，所述承插钢管的外周浇筑有微膨胀抗渗混凝土，所述微膨胀抗渗混凝土的外周设置有基础底板和位于基础底板下方并与地基土层搭接的基础底板垫层，本发明可有效提高降水井封闭质量，减少渗漏隐患，封井效果好，节约施工成本，质量、经济效益突出。
