摘 要:通过改进高喷机的旋转扭矩,增大钻杆内气杆口径,利用压缩空气作进钻下沉动力代替岩芯钻机造孔,减少施工机械,钻灌一气呵成,节约能源,质量可控,实践证明效果好,负面影响小,且改进技术容易掌握,应用前景好.By improving the rotational torque of the high pressure jet machine, increasing the rod diameter of the drill gas pipe, compressed air is injected into the drill to sink power instead of the core drill pore - reducing construction machinery, which reduces the amount of engineering machineries, realizes drilling and grouting synchronically, energy conservation and quality control. The practice shows that it could offer a good result with less negative impact, the improved technology is simple, and shows good application prospects.
