韩渭西煤层气管道工程冲沟地段管道穿越施工的几种方法

Several Construction Methods for Pipeline Crossing Gullies in Han-Wei-Xi Coalbed Mathane Pipeline Project

韩渭西煤层气管道工程第一标段线路在陕西省渭南市合阳县穿越多处冲沟,冲沟地段坡度大、距离长、穿越情况复杂。文章介绍了使用挖掘机,分别采用管道单根焊接顺管法、整体预制顺管法、斜井穿越方式等进行各种冲沟穿越施工的方法。

The first bidding section of Han-Wei-Xi Coalbed Mathane Pipeline Project crosses some gullies at Heyang County of Shaanxi Province,where the gullies are long and steep so as to bring complicated problems to pipeline crossing.In this paper,several methods for pipeline crossing the gullies are illustrated,including using excavators,welding single pipe on site or getting pre-welded integral pipes then sliding them along slope,as well as digging inclined well for pipeline crossing.
