长江大保护建设中管网非开挖修复综合技术

Comprehensive Technologies for Pipeline Non-excavation Repair in Yangtze River Protection

在长江大保护岳阳项目中,通过CCTV检测分析,针对管道存在的错口、破裂、变形、渗漏等不同结构性缺陷及管道破损程度,采用不同的非开挖修复施工技术,不仅解决开挖修复及单一开挖修复问题,且施工周期短、城区开挖交通压力较小、工程质量和安全能得到较好的控制。

In the Yangtze River Protection of Yueyang,for different structural defects and degrees of pipe damage,such as wrong opening,fracture,deformation and leakage,through CCTV detection analysis,different trenchless repair construction techniques are adopted. The problem of excavation repair and single excavation repair is solved. Moreover,the construction period is short,the traffic pressure of urban excavation is small,and the quality and safety can be controlled.
