摘要
非开挖技术是市政给水管道施工常用技术,可以适应不同地质情况、施工条件与设计要求,深入地下作业,最大程度降低管道施工作业对周边环境的影响。因此,本文以一个工程为例,简单介绍了非开挖技术优势,并从管道铺设、水平定向钻进施工、导向孔施工、预扩孔施工、回拖管线施工、管线修复几个方面,对市政给水管道非开挖施工技术的具体运用进行了简单分析,希望为市政给水管道非开挖施工作业开展提供一些参考。
Trenchless technology is a commonly used technology for municipal water supply pipeline construction,which can adapt to different geological conditions,construction situations,and design requirements,conduct deep underground operations,and minimize the impact of pipeline construction on the surrounding environment.Therefore,taking a project as example,this article briefly introduces the advantages of trenchless technology,and analyzes the specific application of trenchless construction technology for municipal water supply pipelines from several aspects such as pipeline laying,horizontal directional drilling construction,guide hole construction,pre-expansion construction,drag-back pipeline construction,and pipeline repair,which could provide some reference for the trenchless construction of municipal water supply pipelines.
