简议非开挖技术在市政给水管道施工中的应用

Brief Discussion on Application of Non-excavation Technology in Municipal Water Supply Pipe Construction

市政工程的施工质量关系到城市服务质量与居民的居住舒适度,因此必须要做好市政工程的施工质量控制,同时利用更先进的施工技术来降低市政工程施工队周边居民产生的影响。此文以个人工作经验为基础,探讨了市政给水管道施工中非开挖技术的相关内容。首先分析了非开挖技术给水管道施工的基本原理,并阐述了非开挖技术的优缺点;接着从管道铺设、水平定向钻进施工、导向孔施工、预扩孔施工、回拖管线施工、管线修复等方面分析了非开挖技术在市政给水管道施工中的具体应用情况;最后指出了市政工程给水管道非开挖施工的若干注意事项,为今后更好的应用非开挖技术提供了参考与借鉴。

The construction quality of municipal engineering is related to the quality of urban service and residents'living comfort,so it is necessary to control the construction quality of municipal engineering,and use more advanced construction technology to reduce the impact of municipal engineering construction on surrounding residents.Based on personal work experience,this paper discusses the relevant content of trenchless technology in municipal water supply pipeline construction.Firstly,the basic principles of non-excavation technology for water supply pipeline construction are analyzed,and the advantages and disadvantages of non-excavation technology are explained.Then it analyzes the specific application of trenchless technology in municipal water supply pipeline construction from the aspects of pipeline laying,horizontal directional drilling construction,guide hole construction,pre-reaming construction,back hauling pipeline construction,pipeline repair,etc.;finally,it points out some precautions for trenchless construction of municipal water supply pipeline,which provides reference for better application of trenchless technology in the future.
