Rotary drilling rig is updated
Rotary drilling rigs were replaced. In 2004, we invented the patent for the excavator to install rotary drilling, and created a new pattern of pile foundation hole forming, small wheel rotary drilling and small crawler rotary drilling. It has been a full decade, and the market is conservatively estimated at thousands. For the small pile foundation hole forming market, it has become a substitute function that cannot be replaced by large rotary drilling. Of course, there are also many counterfeiters, such as shoddy (such as many counterfeiters in Shandong Tengzhou), which disrupt the market with low price, high failure rate and single function. Can only be used under loose geological conditions. Today, we have once again created a revolution that can completely solve the effects that can not be achieved even with large rotary digging. As we all know, there are three major problems in pile foundation hole formation, 1. Large diameter, 2. Collapse, 3. Hard geology (rock formation) The rotary drilling can completely solve such problems; First, the large-diameter hole can no longer cost millions of dollars to purchase equipment, the weight of the equipment does not need tens of tons, and no special vehicles are needed for the transition, which costs huge freight. Second, the landslide is not required to be sleeved, and no sling machine is required. Third, completely eliminate the pressurization mode, whether it is the press-type drill pipe pressurization, or the cylinder plus wire rope pressurization, even the hard formation (rock formation) no need to pressurize the method, of course, do not use the down-the-hole hammer and air compressor Supporting, it can also enter the rock efficiently.
