液压裂管技术在污水管道原位置换中的应用

Application of Hydraulic Pipe-fracturing Technology in In-situ Sewage Pipe Replacement

摘要:

介绍了液压裂管技术的工作原理、施工步骤，并结合在长春污水管道更换的施工案例，对液压裂管技术应用于污水管道原位置换的施工步骤、施工遇到的问题和处理措施、以及施工注意事项进行了详细的阐述。在该工程中，液压裂管技术体现出了其独特的优势，取得了很好的效果，其中的经验为今后的非开挖换管工程提供借鉴。

Abstract:

This paper mainly introduces the working principles and construction steps of hydraulic pipe-fracturing technology. Combining with the construction case in Changchun sewage pipeline replacement, the detail exposition are given to the construction steps, the difficult problems and treatment measures as well as the construction precautions for the application of the hydraulic pipe-fracturing technology in sewage pipeline in-situ replacement. In this construction, hydraulic pipe-fracturing technology showed its unique advantages with good effects, the experience can be reference to the trenchless pipe replacement.
