现在的地下中低压燃气管道大都是使用PE管材,而且一般使用的施工工艺都是开挖铺设,但是在进行铺设中会遇到很多的情况,例如出现了障碍物,或者市政不允许进行开挖等不能直接进行开挖铺设,现在国内通常使用的是定向穿越的方法(非开挖)来对管道进行铺设的。本文主要是对铺设施工的工艺和在施工的过程中存在的重点和难点要一一的进行分析,尤其是管道的标志标示和竣工的资料,同时还对几台仪器对管道定向穿越的具体情况进行分析,在示踪线没有出现问题的时候,对检测管道走向的检测就要使RD8000和探地雷达相互结合,首先要满足的条件是是开挖、停气、开孔,然后在使用高精度管线仪能,这样就可以准确的检测到管线的走向。
Nowadays, most of the underground LPG gas pipelines use PE pipe, and most of the commonly used construction techniques are excavation and laying, but there are many situations during the laying process, for example, there is an obstacle or the municipal government does not allow excavation Can not be directly carried out excavation and laying, now commonly used is the method of directional crossing (trenchless) to the laying of the pipeline. This article mainly analyzes the process and the key points and difficulties in the process of construction, in particular, the marking of the pipeline and the completion of the information, but also on the specific circumstances of several instruments on the pipeline directional through Analysis, there is no problem in the tracer line, the detection of the pipeline to detect RD8000 and ground penetrating radar will make the combination of each other, the first to meet the conditions of excavation, gas, openings, and then use the high Accuracy pipeline instrument can, so you can accurately detect the pipeline to the direction.
