Down-the-hole drilling rigs are used more and more widely in grouting operations, and most of the grouting reinforcement is open-air operations. This article mainly discusses how to choose the model of  crawler mounted DTH drilling rig s. 1.Selection principle (1) Applicable in production The selected drilling rig should meet the needs of the project construction, and should be reasonably configured according to the construction tasks undertaken by the enterprise under normal conditions, taking fully into account the scope of application of the drilling rig. Demand, only the drilling rig with strong applicability in production can better show its investment effect. (2) Technically advanced While meeting production needs, it is required to maintain its advanced performance indicators, which is conducive to extending its technical life. It will face obsolescence in the short term. In the long run, it meets the requirements of sustainable development of enterprises and can ...

Disadvantages: Rotary drilling rigs are also constrained by various conditions such as the geological conditions of the stratum being constructed, the machine's own factors, and man-made factors such as the operator. There are some currently difficult situations to deal with, which are mainly not suitable for hard formations. In the initial stage of the use of rotary drilling rigs, blind superstition or lack of understanding of rotary drilling rigs can easily give people the illusion and cause misunderstanding, which directly affects the use of rotary drilling rigs. Rotary drilling rigs are also constrained by the geological conditions of the formation. In hard rock formations, dense cobblestones, and solitary rock formations, drilling becomes more difficult. Failure to replace the drill bit is prone to accidents. Although it can be equipped with core drills, impact drills, and grab cone drills for hard rock formations, pebble formations with a particle size of more than 100 mm,...

Crawler Mounted Versatile Well Drilling Rig hydraulic drill rig ,   hydraulic drilling rig New, efficient, and versatile Rated Drilling Depth 600m Site Condition It is mainly applicable to the drilling process of wells, monitor boreholes, dewatering boreholes, relief boreholes and gas layers and other exploitation projects. Product Features JKS600B crawler mounted versatile well drilling rig is a new, efficient and multifunctional drill rig, mainly applicable to the drilling process of wells, monitor boreholes, dewatering boreholes, relief boreholes and gas layers and other exploitation projects. When drilling in the rock layer, the rig adopts DTH percussive hammer for penetration and compressed air for cleaning, the penetration speed being dozens of times quicker than conventional rotation rigs. In loose rock, the rig employs a cutting bit or cone bit and uses mud to clean the dirt, its versatility suiting for all kinds of complex geological conditions. Its versat...

Hydraulic technology of  Hydraulic Drilling Rig  is a new technology that develops late but develops rapidly. It is gradually developed on the basis of fluid mechanics. It mainly uses the pressure of the liquid to transmit the force and torque, the so-called hydraulic transmission. Proper use and maintenance of the hydraulic system is an important factor in ensuring the normal operation of the system and extending its service life. (1) Prevent contamination of hydraulic oil. The pollution of hydraulic oil refers to the incorporation of air, moisture, dust and insoluble sediments generated by self-oxidation from the outside. The contamination of the oil will aggravate the wear between the relatively moving parts in the hydraulic components, resulting in throttling holes. Blockage or slipper motion is stuck, and the chemical stability of the broken ring oil accelerates the generation of oxides and the decomposition of organic impurities in the oil. According to statistics, mo...
