[0002] Directional long-hole pre-drainage of coal seam gas is a common regional gas control measure at present. In the process of directional drilling construction, clean water is used as the common hole washing liquid. After being pressurized by a pump truck, the clean water sequentially passes through a high-pressure water supply rubber pipe and a drill rod hollow to reach the hole bottom, so as to achieve the purposes of flushing coal slag and cooling the drilling tools. The commonly used water pipe is a high-pressure rubber pipe, the two ends of which are connected with the pump truck and a water pipe respectively. The redundant part is placed on the floor and the end connected with the water pipe naturally droops under the action of gravity and has a certain angle, which increases the water supply resistance. In the process of normal construction, the water pipe moves with the water pipe, and the excessive bending is easily formed between the redundant pipe placed on the floor and the water pipe. Meanwhile, the vibration and friction between the high-pressure water supply rubber pipe and the floor during high-pressure water supply aggravate the damage of the high-pressure water supply rubber pipe, which greatly shortens the service life of the high-pressure water supply rubber pipe, accelerates the material loss, and increases the construction cost.
