Inspection hole drill hole drill work before as a large ore excavation machinery and equipment, before the usual start of work in general have trouble checking maintenance machinery and equipment, accident prevention failure. During normal use, the work before the job is how to prepare it? The first point is the maintenance personnel must carefully check whether gas water pipe connections are secure, there is no leak leaking phenomenon, deep drilling rig, control in the drilling process, a drill item empty phenomenon, to avoid damage to the drill bit. It has filled the second point is to check the oiler oil, which is the basic common sense to check power system must be checked. The third point is to check the various parts of screws, nuts, joints, etc. is already tightened the top of the column is indeed very strong. Do the work of three of the above checks, to start submersible drilling rig began operations. Rig industry in China rise late, but as China's economic development, the rapid rise of construction throughout the building, rig this rising star in the international rig market development show a unique charm. Drill Development is the epitome of China's construction machinery development rig also represents the future trend of machinery development. Rig was placed a lot of expectations and concerns. Rig toward multi-functional, efficient, deep drilling rig models, intelligence, precision of direction. Drill anchor hole drilling pit urban high-rise buildings (overburden drilling with pipe). Railway tunnel construction process with the same pipe roof drilling process. Rig applications: ground source heat pumps and hydropower cofferdam grouting hole drilling. 1. If the overburden depth ≤30 meters, and the sand and gravel is relatively small, can be imported power head rotary single-acting double rotation, that is, within the drill pipe, casing while rotating and shock, deep drilling rig, using high pressure water slag, Pulling sleeve high efficiency, reduce construction costs. The use of high pressure air DTH drilling in bedrock, drilling to a depth of 250 meters. 2. If the overburden depth> 30 m, sand or gravel is relatively large, can be realized using imported power head drill pipe, casing while rotating, the impact of the use of high pressure DTH with eccentric / reaming drill on the heart to achieve. On the bedrock utilizing high pressure pneumatic DTH hammer drilling, drilling depth of 250 meters. Long industry machinery (Figure) _ _ deep deep drilling rig drilling rig model by Dragon Machinery Co., Ltd. Shandong. Machinery Co., Ltd. Shandong Long (www.longyejixie.com) located Daiyue Tai'an City youth entrepreneurship Park Yung road. Scraps and development in the wave of market economy, the current Long industry machinery has a high profile in the engineering machinery parts, and enjoys a good reputation. Long industry machinery made whole network business alliance certification, marking our service and management level has reached a new height. Long industry machinery staff is willing to joint development with all people a better future.
