Abstract
There is not professional wire-line coring drilling tools for tunnel exploration in China at present. This paper designed wire-line coring drilling pipe specially used in tunnel, spear-head holding equipment, and composite position of the resilient clip, quick break switch of inner pipe assembly and special transport and fish machinery after considering the particular tunnel exploration environments. Finally, field experiment proved that this wire-line drilling tool was a successful tried, which solved the contradictions between the ground wire-line coring drilling tool and the special tunnel exploration environment.关键词
