Segmented opening and closing type grouting pipe and grouting reinforcement method
The invention discloses a segmented opening and closing type grouting pipe and a grouting reinforcement method.The segmented opening and closing type grouting pipe comprises a communicating pipe and a grout outlet pipe, the grout outlet pipe is connected to the lower end of the communicating pipe and communicates with the communicating pipe, a plurality of grout outlet holes are formed in the peripheral side of the grout outlet pipe, and the grout outlet holes are communicated with the communicating pipe. The plurality of slurry outlet holes comprise normally-open holes and normally-closed holes, and after slurry is discharged from the normally-open holes, the normally-closed holes can be opened to discharge the slurry. According to the segmented opening and closing type grouting pipe, the influence range of grouting reinforcement can be accurately controlled, reinforcement of a specific soft soil layer is achieved, normal operation of existing structures and equipment is not affected, the targeted reinforcement effect on the special soft soil layer in a specific area is achieved, and the operation requirement of a complex limited space is met.
本发明公开一种分段开闭式注浆管及注浆加固方法，所述分段开闭式注浆管包括连通管以及出浆管，所述出浆管连接在所述连通管的下端，且与所述连通管连通，在所述出浆管的周侧设有多个出浆孔，多个所述出浆孔包括常通孔以及常闭孔，其中，在所述常通孔出浆后，所述常闭孔能够开启并出浆。本发明提供的分段开闭式注浆管能够精准控制注浆加固的影响范围，达到实现对特定软弱土层的加固补强，不影响既有构筑物及设备的正常运转，实现对特定区域内特殊软弱土层的靶向加固效果，满足复杂受限空间的作业要求。
