Karst foundation treatment and protection grouting reinforcement method
The invention relates to a karst foundation treatment and protection grouting reinforcement method. The karst foundation treatment and protection grouting reinforcement method comprises the steps that an area needing to be treated is divided into at least one reinforcement block; s2, grouting holes are formed in the reinforcing blocks, the relevance of the corrosion holes is detected, and the grouting holes are divided into the grouting holes which are obviously communicated with the corrosion holes and the grouting holes which are not obviously communicated with the corrosion holes; s3, grouting is conducted on the key reinforcing area, and then grouting is conducted on the peripheral reinforcing area; in the grouting process, grouting is conducted in the mode that the corrosion holes are obviously communicated with the grouting holes, grouting is conducted through a bag type stop-grouting plug sealing grouting method, then grouting is conducted in the mode that the corrosion holes are not obviously communicated with the grouting holes, and grouting is conducted through in-hole drainage and grout circulation grouting methods. Targeted grouting reinforcement is adopted according to the connectivity of the corrosion holes, the defect that at present, the corrosion difference condition existing in building grouting on the soluble gypsum rock stratum is not subdivided is overcome, rock stratum stagnant water can be effectively discharged, and the grouting reinforcement effect is better.
本发明涉及一种岩溶地基治理及防护注浆加固方法，包括：将需要治理的区域划分为至少一个加固区块；S2、在各个加固区块内设置注浆孔，并检测溶蚀孔洞的关联性，将注浆孔分为溶蚀孔洞明显连通注浆孔和溶蚀孔洞非明显连通注浆孔；S3、先对重点加固区进行注浆，再对外围加固区进行注浆；在注浆过程中，先进行溶蚀孔洞明显连通注浆孔的注浆，采取囊式止浆塞封闭注浆法进行注浆，再进行溶蚀孔洞非明显连通注浆孔的注浆，采用孔内排水、浆液循环注浆法进行注浆。本发明根据溶蚀孔洞连通性分别采取针对性的注浆加固，克服了目前针对可溶性膏岩地层上建筑物注浆对存在的溶蚀差异情况并无细分的不足，能有效排出岩层滞水，注浆加固效果更好。
