The gearbox of Xining auger drill can slide up and down along the slideway of the drill frame to ensure the verticality of the drilling.Xining DTH drill rigs allow more people to enjoy a healthy life and realize the sustainable development of social and corporate benefits.Xining DTH drilling rig business is mainly oriented to many fields such as subways, tunnels, petrochemicals, coal chemicals, and large industrial and civil buildings..Xining DTH drilling rigs will be committed to providing new and old customers with better quality, better service, and more cost-effective drilling rigs, and will be the icing on the cake for our customers' engineering construction and supporting products!

Inspection of casing and drill pipe joints of Qinghai drilling rig: The casing should be tightened when connecting, and the joint should be prevented from loosening when there is a joint exposed outside..The drill pipe must be tightened to prevent back-off from the drill pipe joint when the drill tool is reversed.When the Qinghai drilling rig finds rotation resistance or the outer casing is rotating along with it, lightly lift the drilling tool to blow the hole. If there is too much mud when the slag is discharged, water should be injected into the hole and the spray is discharged to discharge the mud..Since its establishment, Xining Drilling Rig has developed rapidly and steadily in the industry with its team, strict management, and excellent service.

Xining DTH drilling rig is a rotary percussion drilling rig.The impactor is directly submerged into the bottom of the hole to drill the rock, the impact energy transmission loss is small, and the drilling efficiency is high..Qinghai down-the-hole drill rigs sincerely thank friends from all walks of life for their support and love, wholeheartedly serve customers, and warmly welcome new and old customers to visit us.Xining DTH drill rigs have a full range of varieties, strong technical force and good after-sales service, which has created a good reputation.Qinghai drilling rigs reduce noise and dust hazards, safe production, and improve working conditions.

When the Qinghai drilling rig discovers casing deflection when drilling holes, it should be adjusted in time to ensure the accuracy of subsequent pipe follow-up.Problems encountered in the follow-up drilling of Qinghai pipe shed drilling rigs and their solutions.Xining Pipe Shed Drilling Rig Concept: Honesty, Long-term Service, Winning by Quality!The general sequence of construction of the Qinghai pipe shed drilling rig is: drilling and synchronously following seamless steel pipes  washing holes  placing steel cages in the steel pipes  pressure injection of cement slurry.Xining pipe shed drilling rigs provide users with genuine products and good services, which have been unanimously recognized and praised by customers.

2 The sensitivity of the safety valve is not high, which causes the fault location system. The jack leg at the end of the drill arm can be stretched vertically or horizontally. The correct positioning method is: extend horizontally before drilling, and then extend longitudinally. After drilling is completed, First retract vertically and then retract horizontally.If the operation sequence is wrong, due to the low sensitivity of the safety valve on which the positioning system is based, the positioning pressure will increase sharply, and failures such as "positioning pipe bursts and oil leakage" in the early use period will occur, which is wasteful and delays tunnel operation time..
