水平钻掘工法简称HDD工法,为铺设地下公共管线所使用之免开挖技术工法之一种,在欧美已行之有年(从1970年来),此工法被普通使用之特点为可在一个设定且可导引之路径与深度,且不破坏开挖道路表面情况下配置地下公共管线.因其可长距离施工,弧形前进,故非常适用于穿越河道,高速公路,地下障碍物,特殊保护区等工程,在欧美...

This paper proposes the idea of implementing the concept of SE in horizontal directional drilling (HDD), a pipeline installation technique which was adopted from horizontal oil well drilling technology. The similarity of the HDD technique with oil well drilling makes SE surveillance a very useful ...
