浅谈穿铁路顶管压力钢管的施工工艺

Construction Technology of Wearing Steel Pipe Jacking Pressure Steel Pipe

随着城乡建设的迅速发展,水利、电力、公路、铁路等公共设施不断完善,地面及地下水网、路网、管网、电网交错布置,各建筑物多存在交叉现象,为减小对周围建筑的影响,利用较小的施工场地完成工程建设任务,而发展了顶管技术,并在顶管内进行其他结构物施工。本工程将以蒙开个地区河库连通工程长桥海水库输水管施工为例介绍压力钢管在顶管内的施工方法。

With the rapid development of urban and rural construction,public facilities such as water conservancy,electric power,highways and railways have been continuously improved.The ground and groundwater networks,road networks,pipe networks and power grids are staggered,and there are many cross-over phenomena in each building.The impact of the surrounding buildings,the use of smaller construction sites to complete the project construction tasks,and the development of the pipe jacking technology,and other structural construction in the pipe jacking.This project will introduce the construction method of the pressure steel pipe in the pipe jacking by taking the construction of the long bridge sea water pipe of the river bank connecting project in Mengkai area as an example.
