Guangzhou Zhenyu Company's down-the-hole hammer rock drilling rig, rock drilling assembly of more than 20 sets (units), has achieved rapid rock drilling with a diameter of 500 MM in China Haihua Island project site. Efficient and fast, highly praised by experts and owners! Expand the full text Guangdong Zhenyu Group The down-hole hammer assembly produced by Guangzhou Zhenning R & D Center has realized CFG long auger drill with large diameter down-hole hamparticular, it is committed to the development of construction equipment and new technologies in the field of down-the-hole hammer drilling. Focus on providing customers with the best foundation construction scheme in the fields of long spiral combined with down-the-hole hammer drilling construction, rock guide hole construction, pouring pile foundation construction, etc. The long auger drill provides support and power, and the down-the-hole hammer breaks the stone into the rock. Through the air compressor, the stone powder is brought to the ground and then the hole is formed. Guangzhou Zhenyu has a professional technical team, and Guangzhou Zhenyu Foundationg auger drilling into rock formation Down-the-hole hammer impactor. Combined hole guiding technology of large-diameter down-the-hole hammer and long screw multifunctional pile driver. Rock-socketed drilling tool assembly of long auger drilling machine: down-the-hole drilling tool assembly, impactor oiler, oil storage tank, buffer, telescopic drill pipe, hexagonal joint. Drill rod for down-the-hole hammer drill. Hexagonal quick coupling drill pipe. The perfect combination of long auger drill and impactor down-the-hole hammer, and the combination of large diameter down-the-hole hammer and long auger multifunctional pile driver. Overcome the problem of long spiral into the rock. And the foundation construction of the long spiral drilling machine in the rock stratum is realized. And provide one-stop comprehensive services for this purpose. Dth hammer is more and more widely used in foundation construction. Pecially in the pebble layer, the boulder layer, The Luogang section of Guangzhou Metro is a famous problem in foundation construction, mining dth bit , which is famous for its large boulders, limestone, high hardness and slight weathering. Zhenyu, with many years of mature down-the-hole hammer rock technology, has successfully realized 800 MM down-the-hole hammer drilling in slightly weathered rock layer. The diameter of 80o the drilling rig and drill pipe. [Low cost of use] 1, the sub-hammer and the drill bit can exchange positions, wear evenly, and have long smption, low cost,Borehole Drill Bits, high efficiency into the rock and good environmental protection.
