Concentrated leakage water gushing blocking method of underground chamber
The invention discloses a concentrated leakage water gushing blocking method of an underground chamber, relates to the technical field of underground engineering, and provides a treatment method for blocking and repairing a water gushing point so as to solve the problem of leakage water gushing of the underground chamber in the condition of high water pressure, so that safe operation of a buildingand normal operation of subsequent construction projects are guaranteed. According to the technical scheme, the concentrated leakage water gushing blocking method of the underground chamber comprisesthe steps of performing surface layer reinforcement and reinforced grouting first so as to form a cover weight support for top water grouting of a drainage hole; then drilling the drainage hole, andshunting and draining gushing water at the water gushing point, so that the pressure relief effect is achieved, and the water amount of the original water gushing point is reduced; then performing caisson drainage, so that the cover weight can be provided for a grouting hole when the water gushing point is grouted and blocked; then grouting, blocking and reinforcing the water gushing point; then grouting and blocking the drainage hole, and performing a closed water test; and finally, removing a temporary blocking facility of the water gushing point. The concentrated leakage water gushing blocking method is suitable for blocking and repairing the gushing water of the underground chamber under high external water pressure.
本发明公开了一种地下洞室集中渗漏涌水封堵方法，涉及地下工程技术领域，针对地下洞室在高水压力条件下出现渗漏涌水的问题，提出一种封堵涌水点并进行修复的处理方法，保证建筑物的安全运行和后续施工项目的正常进行。本发明采用的技术方案是：地下洞室集中渗漏涌水封堵方法，先进行表层加固及补强灌浆，形成引排孔顶水灌浆的盖重支撑；然后钻引排孔，对涌水点的涌水进行分流引排，起到泄压的作用，减小原始涌水点水量；再进行沉箱引排，涌水点灌浆封堵时能够给灌浆孔提供盖重；再对涌水点进行灌浆封堵并加固；再灌浆封堵引排孔，进行闭水试验；最后拆除涌水点的临时封堵设施。本发明适用于地下洞室高外水压力下涌水的封堵及修复处理。
