Anchor rope opening water burst blocking construction method
The invention relates to the technical field of anchor cable opening water gushing plugging, and discloses an anchor cable opening water gushing plugging construction method which comprises the steps that (1) pipe-following drilling construction is adopted to form an anchor hole, and a sleeve is arranged in the anchor hole in a sleeved mode; (2) an anchor cable, a primary normal-pressure grouting long pipe, a secondary high-pressure splitting grouting long pipe, a primary grouting short pipe and a secondary grouting short pipe are synchronously put into the anchor hole; the bottom of the primary normal-pressure grouting long pipe and the bottom of the secondary high-pressure splitting grouting long pipe extend to the bottom of the anchor hole, and the bottom of the primary grouting short pipe and the bottom of the secondary grouting end part extend to the free section; (3) pure cement paste is injected into the anchor hole through the primary normal-pressure grouting long pipe; (4) the sleeve is pulled out; (5) mixed slurry formed by mixing pure cement paste and a water glass solution is injected into the free section through a primary grouting short pipe; (6) pure cement slurry is injected into the anchoring body in a high-pressure splitting mode through a secondary high-pressure splitting grouting long pipe; and (7) pure cement slurry or mixed slurry is injected into the free section in a high-pressure splitting mode through the secondary grouting short pipe.
本发明涉及锚索口涌水封堵的技术领域，公开了锚索口涌水封堵施工方法，1)、采用跟管钻进施工形成锚孔，锚孔中套设有套管；2)、在锚孔中同步下入锚索、一次常压注浆长管、二次高压劈裂注浆长管、一次注浆短管以及二次注浆短管；一次常压注浆长管的底部及二次高压劈裂注浆长管的底部延伸至锚孔的底部，一次注浆短管的底部及二次注浆端部的底部延伸至自由段；3)、通过一次常压注浆长管往锚孔中注入纯水泥浆；4)、将套管拔出；5)、通过一次注浆短管往自由段中注入纯水泥浆与水玻璃溶液混合形成的混合浆；6)、通过二次高压劈裂注浆长管往锚固体高压劈裂注入纯水泥浆；7)、通过二次注浆短管往自由段高压劈裂注入纯水泥浆或混合浆。
