- 摘要:
- 针对短距离、小范围淤积或沼泽地的管道穿越施工难的问题,介绍一种有效的施工方法———拖管法。采用该方法不需要常规施工机具在泥沙淤积现场行走,而且对防止管沟壁塌落效果明显,其施工成本仅为定向钻孔穿越施工方法的一半,但与之相比该方法的施工速度较慢、劳动强度较高.
In connection with pipelaying in a small silt or marsh area,a effective construction method-hauling pipe method was in troduced .It needn't conventional machines & tools walking in silt area and it can protect trench wall against collapse.The cost only is half of directional drilling pipe crossing cost in silt area. But construction progress was slow & operation was hard.2000,6(6): 22-23 收稿日期：2000-8-1
