摘要
岩土工程中的高陡边坡堆积体的锚固工程中经常遇到的由于边坡高陡、钻机架设搬迁困难、底层破碎成孔困难等,有针对性地选用了相应的锚固钻机,并对钻机进行了改进,以使其更加符合高陡边坡堆积体锚索施工的要求;同时研制加工了符合该类地质情况的偏心跟管钻具。以期能够解决高陡边坡堆积体锚固成孔困难、效率低、造价高的难题。
Because of high-steep slope, difficulties are often encountered, such as drilling rig relocation & erection and borehole completion in crushed bottom. Anchor drill was selected and improved in order to meet the requirements for the anchor cable construction in accumulation body at high-steep slope; and meanwhile eccentric drill with easing was deveF oped and manufactured, hoping to solve the difficulties of anchoring borehole construction in accumulation body at high- steep slope, overcome low efficiency and high cost.
