Description

TECHNICAL FIELD

[0001] The utility model relates to the field of coal mine directional long drilling construction, especially relates to a directional long drilling hole orifice sewage collection device. BACKGROUND

[0002] Directional long drilling is a drilling technology specially used in underground mining, engineering construction, geological exploration and other fields. Unlike ordinary drilling, directional long drilling can achieve precise trajectory control and directional drilling by controlling the direction and angle of the drill bit according to engineering requirements. It is suitable for complex geological structures and limited space to reach the specified location for directional drilling or resource collection.

[0003] During the drilling process, sewage is usually produced. These sewage is mainly a mixture of drilling fluid and drilling rock debris. The role of drilling fluid is to lubricate the drill bit, cool the equipment and carry away the drillings, but during the drilling process, these drilling fluids and substances in the stratum mix to produce sewage containing rock debris and other impurities. These sewage flows out of the hole and spreads everywhere. In the past, in order to prevent sewage from polluting the site, workers used a "waterproof cover" device. The periphery of the waterproof cover is made of sponge material and is connected to a drain pipe to play the role of sewage discharge. However, the waterproof cover is difficult to use and needs to be pressed and fixed by hand, which is inconvenient to operate.
