XY-1型岩芯钻机在水平钻孔施工中的应用

Application of the XY-1 type core drilling machine to horizontal drilling

利用XY-1型岩芯钻机,在不影响现有道路、铁路等设施正常使用的情况下进行地下水平钻孔,实现非开挖敷设中、小型管线的施工.

Horizontal drilling using an XY-l-type core drilling machine was conducted, so as to avoid disturbing the normal operations of existing roads, railways and other surface facilities, and to facilitate the construction of small-and medium-sized pipelines without earth excavation.
