Sleeve valve pipe grouting structure and grouting method in pipe withdrawing process
The invention discloses a sleeve valve pipe grouting structure and grouting method in a pipe withdrawing process, and belongs to the field of pipeline construction. The sleeve valve pipe grouting structure comprises a plurality of vertical sleeve valve pipes, wherein the plurality of vertical sleeve valve pipes are installed in cemented soil, the cemented soil is used for filling gaps generated in the front part of a pipe body after pipe withdrawing, each sleeve valve pipe comprises a valve pipe body, a plurality of one-way valve ports are formed in the valve pipe body at intervals, a core pipe which is used for injecting reinforcing slurry is installed in the valve pipe body, a slurry outlet part is arranged on the core pipe, a plurality of slurry outlets are formed in the slurry outlet part, and sealing pieces are installed above and below the slurry outlet part. The cemented soil in a mud making area can be reinforced by the sleeve valve pipe grouting structure, and the problem of damage to nearby communication cables due to sedimentation of the cemented soil in the prior art is solved.
本发明公开了一种退管过程中的袖阀管注浆结构及注浆方法，属于管道施工领域，包括安装在水泥土中的若干个竖直方向的袖阀管，所述水泥土用于填充退管后在管体前部产生的空隙，所述袖阀管包括阀管管体，所述阀管管体上间隔设置有若干个单向阀口，所述阀管管体内部安装有用于注入加固浆的芯管，所述芯管上设有出浆部，所述出浆部上设有若干个出浆口，所述出浆部的上方和下方均安装有密封件，通过袖阀管注浆结构可以对打泥区的水泥土进行加固，解决现有技术在退管过程中，由于水泥土沉降，容易导致附近的通讯电缆被破坏的问题。
