胀圈内衬修复结合压密注浆技术在加固工程实例中的应用

Analysis of the Application of Expansion Ring Lining Repair Combined With Pressure Grouting Technology in Reinforcement Engineering

通过对大直径破损市政管道采用不锈钢双胀圈局部内衬修复,对塌陷道路路基进行压密注浆加固的施工实践,对破损管道裂缝修补、管节头内衬双胀圈柔性防渗和管基、路基注浆加固工艺技术要点进行分析,对区内开展类似的工程实践具有借鉴意义。

Through the construction practice of compact grouting reinforcement of collapsed road subgrades by using stainless steel double expansion rings for large-diameter damaged municipal pipelines, the technical points of flexible anti-seepage of double expansion rings lined with pipe joints, and the technical points of pipe foundation and subgrade grouting reinforcement are analyzed, which is of reference significance for carrying out similar engineering practices in the region.
