Grouting sealing bag type dewatering well wall water stop structure
The invention relates to a grouting sealing bag type dewatering well wall water stop structure. The upper end and the lower end of at least one sealing bag are fixed to a well pipe, at least one grouting pipe extends into the well pipe from an upper end opening, the grouting pipe transversely penetrates through a wall hole which is reserved in the well pipe through a bypass valve which is arrangedon the grouting pipe and communicates with the inner part of the sealing bag. According to the grouting sealing bag type dewatering well wall water stop structure, the construction quality is reliable, the grouting pipe is arranged in the inner part of the well pipe, the quality is reliable, the quality problem caused by binding gaps between the sealing bag and the well pipe and between the sealing bag and the grouting pipe when the grouting pipe is arranged on the outer side of the well pipe and bounding together is carried out is effectively avoided; and well wall water stopping is reliable, and compared with a traditional well wall water stopping process, the well wall and surrounding soil are extruded through expansion after grouting of the sealing bag, and the well wall water stopping reliability is guaranteed through the high grouting pressure.
本发明涉及一种注浆密封袋式降水井井壁止水结构，至少一密封袋上下两端固定在井管上；井管内自上端口伸入至少一路注浆管，注浆管通过其上设置的旁通阀横向穿过井管上预留的壁孔，与所述密封袋内部连通。本发明施工质量可靠：注浆管置于井管内部，质量可靠，有效避免了注浆管布置于井管外侧，一同绑扎时密封袋与井管、注浆管绑扎间隙所产生的质量问题。井壁止水可靠：与传统井壁止水工艺对比，本方案通过密封袋注浆后膨胀挤压井壁和周围土体，通过较高的注浆压力，确保井壁止水可靠性。
