Cause DTH drill rig card submersible drilling rig usually pay attention to maintenance and lubrication of the machine can reduce the incidence of failure, but will focus on maintenance, although a corresponding decrease after a mechanical failure, but still there will be some failures pile drilling rig maintenance, submersible drilling rig sometimes occur sticking fails, then the general cause of the failure, what does one, drill bits broken wing;? 2, new for large diameter drill bits than the original; 3, drilling machine displacement skew or drill holes; 4, when the rock wall or orifice falling rocks or encounter a major fissures, caverns; 5, in case of mud with stone dust terrain difficult to discharge; 6, negligent operation, long When the time to stop drilling, no blowing rock powder pile drilling rig lowest price, but also did not mention the drill, so that the impact is to be buried rock powder; approach: on the strength of the current drill head, the broken wing has basically put an end, once the event special cases, the available period of almost the same diameter aperture seamless pile hole drilling rigs, pipe built with butter, asphalt and other things connected with the drill pipe into the bottom of the hole, the hole at the end of the broken wing to take out the bottom of the hole before the first salvage blowing rock powder. Drill mention more serious situation is not up, fit to go, the impact does not ring, this time only plus torque or aids to help enhance that drill rotation, then you want the edge to the gas, while lifting the drill, until the fault lifted up. Re-drilling, to be a little pressure, then gradually increase the thrust pile drilling rig sale, until the normal working pressure. For well drilling rig drilling rig views and opinions on the construction of vertical rotation automatic positioning hole for good quality. The degree of compaction testing style has good range of traditional craft some degree of compaction detect errors. As fewer sampling points, poor representation, compaction can not supply comprehensive information of work, time-consuming, labor large, expensive and so on. Require skilled operating skills and poor reproducibility of test effectiveness can not be measured or estimated levels of compaction during compaction, compaction insufficient or excessive compaction. So people have been looking for a way to continue to measure the degree of compaction in the compaction process style. Analysis of geological and hydrological data, real-time adjustments in accordance with geological drilling mud weight and speed, especially for the poor strata have pre-control recourse. Well drilling rig drilling rig working affair may have been said to be rotating bucket, auger or other short homework equipment dry and wet drilling, and with auger successive earth. 1.) reincarnation homework from the foundation holes for rig functions. Chiang Khong time to discharge mud and sand ratio of the rate of change into the mud of the sand close to appropriate. The basic construction of the case because the pile of extraordinary quality processes can easily cause the slightest negligence matters, so adhere to the principles of the construction has been focusing on prevention: Enhanced construction into the hole, steel cage construction installation, underwater concrete pouring and other various aspects of the process RBI norms in accordance with the design and construction skills to solve various problems during the construction of real-time rendering. 2) When drilling in shallow water, the use of the Island building construction. Goose head designed main winch rope pulley promotion force detection, can realize the following functions: real-time detection and display the main volume rope promotion force in the display; when fighting reached the bottom of the hole drilling, hydraulic system led by moderation signal will automatically cut off the main winch oil.
