Urban underground engineering strong karst water treatment construction method
The invention relates to the technical field of underground station construction, and particularly relates to an urban underground engineering strong karst water treatment construction method. The method comprises the following steps that S1, construction preparation is carried out; S2, karst boundary judgment is carried out; S3, drilling detection is carried out, a drilled grouting hole is utilized, the lithology, the geological structure and the underground water condition information of a drilling passing area are observed during drilling, and stratum, geousness and joint crack characteristics are preliminarily obtained; S4, a potassium permanganate solution is used for detecting the waterway flow; S5, the height of a balanced water level water head is measured for a water burst point appearing in the foundation pit excavation process; S6, the deep foundation pit excavation water burst is blocked; and S7, a foundation pit deep hole waterproof curtain is constructed. The construction method is complete, clear and detailed in step, construction personnel can conveniently use the method, and the construction safety and the construction efficiency can be effectively improved. The method is mainly applied to the aspect of underground engineering strong karst water treatment construction.
本发明涉及地下车站施工技术领域，更具体而言，涉及城市地下工程强岩溶水处治施工方法。包括以下步骤：S1、施工准备；S2、岩溶边界判定；S3、进行钻孔探测，利用钻进的注浆孔，钻进时观察钻孔穿越区域的岩性、地质结构构造及地下水情况信息，初步获得地层、地性、节理裂隙特征；S4、利用高锰酸钾溶液对水路流经进行探测；S5、对基坑开挖过程中出现的涌水点进行平衡水位水头高度测量；S6、对深基坑开挖涌水进行封堵S7、施作基坑深孔止水帷幕。本施工工法步骤完善、清楚、详细，便于施工人员套用，能够有效提高施工安全性和施工效率。本发明主要应用于地下工程强岩溶水处治施工方面。
