浅谈管道水平定向钻穿越岩石层施工技术

Introduction to Pipe Horizontal Directional Drilling Crossing Rock Construction Technology

始于20世纪70年代的水平定向钻进管线铺设技术,综合了传统的道路钻孔、地质钻探和油气井定向钻进技术。目前,在石油、天然气、自来水、电力和电讯部门,水平定向钻进已是一种得到广泛认可的铺管施工技术。水平定向钻进用于均质土层的穿越能够取得满意效果,在杂填土、砂卵砾石层、冰渍层和硬岩层中的穿越难度增大,但也不是不可穿越。结合陶家山的施工实例,阐述了水平定向钻岩石钻的施工技术。

Began in the seventies of the twentieth century horizontal directional drilling pipeline laying technoIogy, a combination of traditional road drilling, geological drilling oil and gas wells and directional drilling technology.Currently, in the oil, gas, water, electricity and telecommunications sectors, horizontal directional drilling is a widely recognized technique to obtain construction pipe laying.Horizontal Directional Drilling across homogeneous soil can be used to obtain satisfactory results, in miscellaneous fill, sand gravel layer, moraine layer and hard rock crossing more difficult, but it is not impenetrable.Examples of pottery Jiashan combined construction, elaborated construction technology horizontal directional drilling rock drill.
