旋挖钻机钻头的选配与使用

Matching and Using of Hydraulic Piling Rig Bits

旋挖钻机可用于复杂地层施工,其施工技术要求因地而异。合理选择及正确使用钻头,在一定程度上能丰富施工工艺,拓宽施工领域。根据目前常见旋挖钻头的种类及其工作原理,指出与其相适宜的地层,以及施工中应依据钻机的功能配置对钻头、钻具进行选择,同时对应用中须注意的问题进行了说明。

The hydraulic piling rig can be used in complicated strata pile construction; its specifications are different according to local conditions. To select rationally and use bits correctly can diversify construction technologies and broaden construction fields. Based on categories and operational principles of familiar hydraulic piling rigs at present, pointed out their adapting strata, to select bits and tools according to rig functions and expounded issues have to be noted in application.
