拖拉管管道敷设工艺在过路穿管工程中的应用

On Dragging Pipe Laying Technology Applied in the Crossing Projects

用导向钻机安装管道的方法称之为导向钻穿越法(拖拉管)。这是一种非开挖地面就可以在地下快速敷装管道的方法,适用于城市道路和交叉口埋设地下管线,并避免了道路的开挖和对其他地下管线的损坏,同时降低了地下管线施工时对交通、环境的影响。结合工程实例,还简单分析了施工过程中存在的一些问题。

The orientation drill crossing method means to use directional drill to set up pipelines. As a non-excavation and rapid underground pipelaying method, it is appropriate for urban roads and intersections to bury pipelines. The method not only can avoid the excavation of the road and damage for other pipelines, but also lower the influence for the traffic and the environment. Combined with the case, the author has analyzed some problems briefly during the construction process.
