Down-the-hole Hammer: a Breakthrough in Foundation Construction of Haihua Island
Original Title Down-the-hole Hammer Breakthrough in Foundation fastest dth hammer Construction of Haihua Island Dth hammer of Guangdong Zhenyu Group The time is October 2016 Location Hainan Haihua Island Evergrande Project Danzhou Hainan Geological conditions clay backfilled moderately weathered 15m into the rock 25m long pile The problem of foundation construction of the rock layer is solved by hammering into the rock with a down-hole hammer 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 hammer and impactor into rock The foundation construction hole guiding construction and pile foundation construction of CFG in weathered strata such as rocks and the like can be quickly and smoothly completed At the same time it provides one-stop service for rotary excavator users Established in 1998 Guangzhou Zhenning belongs to Guangzhou Zhenyu Mechanical Hydraulic Equipment Factory which is a manufacturing research institution dedicated to the research and development of basic engineering machinery and equipment In particular 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 Foundation Engineering Equipment Research and Development Center has obtained dozens of patents bra tape measure filling the gaps in rock construction technology at home and abroad The production base is located in Huahai Industrial Zone Huadu District Guangzhou Guangdong Province Years of rich experience excellent technology and excellent service have won valuable time and excellent economic benefits for customers at home and abroad Therefore we have won the strong support and trust of our customers Therefore Zhenyu’s products have become the brand products of piling machinery The special features of Zhenyu Machinery’s products and services are 1 Long 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 which is famous for its large boulders limestone high hardness and slight weathering Zhenyu mining dth bit 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 800 MM down-the-hole hammer is slightly weathered in the Guangzhou Metro construction site Zhenyu cluster Dth hammer solves the problem of high cost and high energy consumption in the construction of Dth hammer into rock Application of Sanya Xiangshuiwan 800 CM Cluster Dth Hammer Date March 2016 Location Lingshui Sanya Hainan Project Xiangshui Bay Foundation Construction Project Geological characteristics slightly weathered rock stratum pile length of 18m Comparison of equipment cost drilling tool consumption and energy consumption between Guangzhou Zhenyu 800MM cluster Dth hammer and Korean integral Dth hammer at the construction site of Xiangshui Bay in Sanya Summary PK results the cluster down-the-hole hammer developed and produced by Guangzhou Zhenyu in China is slightly faster in construction progress and slightly lower in energy consumption and the input cost and maintenance cost of the equipment are much lower than those of the integral down-the-hole hammer imported from Korea Dth hammer is more and more widely used in foundation construction Pecially in pebble layer boulder layer slightly weathered red rock moderately weathered and strongly weathered strata the construction schedule and quality problems are solved However the relatively high cost of down-the-hole hammers has always been a problem hindering the popularization of this technology
