拖拉法在污水管道铺设中的应用经验

拖拉法又名水平定向非开挖钻进技术。近几年拖拉法越来越多地应用于污水管道穿越河流、道路及不宜开挖的工程实践中。该技术具有对周围环境影响小,施工安全、高效、综合成本低等独特的优越性,在污水管道铺设工程中得到广泛重视。结合工程应用经验,介绍了工程设计、施工中应注意的技术问题,以期为拖拉管工程的设计、施工提供借鉴。

Application Experience of Pipe Pulling Technology in Sewage Pipe Laying

Pipe Pulling Technology is also called repeated pulling by directional drilling method. In recent years,Pipe Pulling Technology is widely used in crossing rivers,roads and excavation works should not practice for sewage pipe. The technology has little influence on the surrounding environment,construction safety,efficient and low cost. It received wide attention for the unique advantages of the sewage pipeline project. Combined experience in engineering applications,this article introduced the technical issues of engineering design and construction with a view to pipe pulling engineering design and construction provide a reference.
