Rig periodic inspection of item 1, the main structure of the drilling rig status, structural connector bolts connecting pin structure, each structure welds, Barrel and check the condition of safety, especially before entering use, should a qualified units for their safety testing, qualified before use; 2, a variety of regular power head, operating cylinder, check the condition of the drill bit; 3, regular drum winch rope fall prevention device and two side edge height, roll wall situation, the rope trailing in the number of weeks to check on the roll. 4. Check the electrical system, the main test items as: Dedicated electrical box set and short-circuit protection and leakage protection devices, automotive engineering drill where to sell, emergency off switch, electrical boxes damping device, fixed, lighting equipment cable line work , grounding cable can not be used as a carrier zero lines; you Construction Engineering Drill Diamond understand how much? You know Rig Pile Foundation Construction in normal drilling should do the time? Today, we'll take you to understand the content! 1, the cylindrical rotary drilling rig drill in a mud embankment at the bit level when the local space will have a "vacuum", Liujiang County automotive engineering drill, and because of the intersection of the mud hole on the lower part of the casing perforations drill bit embankment liter scour wall, car engineering drill manufacturers can easily lead casing bottom hole wall collapse, automotive engineering drilling equipment, so the surrounding casing must be carefully compacted backfill. 2, the beginning of the drill bucket to fall slowly, and then start drilling. Ground 2-3 meters, pay close attention if the pile deviation. 3, when the drill pipe whereabouts, to control your speed. 4, do not hard embankment drilling drill, soil reaction should be released after the embankment liters. We hope that our presentation today on the drilling rig to make a deeper understanding, if you have any questions, please contact and follow us!
