Currently a large part of the construction of drilling rigs to pass through Quaternary soil, gravel layer and other complex formations, forming aspect of the pile hole, reverse circulation construction impact aperture is generally clay, loam, mucky soil, silt layer construction to prevent collapse hole, 350 drilling machines where to sell, still using positive cycle percussive drilling, but easy necking, but the verticality of the pile is better, according to the data I had several engineering construction show, in rotation Drill into the segment average filling factor is 1.15; and the filling factor of the drilling machine into the segment was 1.25, the filling factor in soil impact and rotary base for drilling rigs is nearly over some preparation before the operation in detail. I believe that through this article, many people will prepare matters for drilling rigs operating before have more understanding, I believe that for many people it is very useful. Small drilling machinery rely gravel from the rotational movement of drilling. A large pot cone hit, 350 drilling machine manufacturer, forward and reverse circulation rotary drilling fight, hydraulic driving head hit machine, DTH play vibration rotary machine. Only a simple rotary drilling playing computer equipment, improve the structure of rotary drilling machine to play two parts, recycling washing equipment consisting of well drilling equipment. Auger playing computer, including rod and starts playing. Nominal diameter rod generally have four kinds of play and 114 mm 60,73,89. By playing a game of heads and full-ring play two categories. Suitable soil, sand, generally smaller than the diameter of the rod to play loose strata, the inner diameter of the inner diameter of the tube hit the big, usually 150? 200 mm, Danzhou 350 drilling rigs, up to 300 mm. However, due to inhalation or squeeze pump capacity limitations, 350 drilling machine equipment, drilling depth is generally less than 150 meters and a depth less than 50 meters high chip removal efficiency. We often hear the impact of playing computer and playing computer DTH, in fact, the principle is the same. Most of the works are based on playing computer and playing computer rotation into technology. Usually small drilling machine can also be used from the beginning through the nozzle at the bottom of the pressurized spray chamber, formed to carry cuttings to fight rising pump water to the spray reverse circulation. It can rise higher rate, a strong ability to discharge debris and pebbles to form a drilling rig in the rate. 350 drilling machine manufacturer, the Prius, Danzhou 350 drilling rigs provided by Luoyang Prius Drilling Equipment Co., Ltd.
