一种实用的黄土塬地带管道施工方法

A Practical Pipeline Construction Method in Loess Tableland

文章针对河南北部黄土塬和黄土沟谷地形地貌的特点,分析了长输管道在该地形下铺设的不同施工方案的优缺点,提出了利用小型定向钻在陡坎附近打斜井的施工方案,该方案投资省、工期短、施工方便、不破坏黄土塬结构,是一种经济实用的好方法。

Aimed at the physiographic features of loess tableland and gullies in North Henan region, the different construction scenarios of long distance pipeline laying are analytically compared and the scenario applying a small-sized directional drilling machine to drill a inclined well in the vicinity of steep slope is brought forward. This scenario is an economical and practical method with advantages of investment saving, short project construction period, easy operation and maintaining loess tableland structure.
