非开挖水平定向穿越铺设地下管线施工技术

Construction Technology of Passing through Underground Piping Laid by Non-Excavation Horizontal in Direction

简要介绍了非开挖水平定向穿越铺设地下管线施工技术的优点,重点阐述了该施工技术成败关键在于施工前对周围原有管网的勘察、钻进泥浆的选择和配制以及优化设计的最佳轨迹曲线这几个重要环节。

The paper briefly introduces the advantage of construction technology of passing through underground piping laid by non-excavation in horizontal and direction.It also mainly states that the key of success or failure is some important rinks,i.e.survey around the original pipe network before construction,selection and disposition of bored sludge as well as the optimum locus curve of optimum design.
