Talent apartment project is a key talent housing project in shenzhen, located in nanshan district high-tech park. The number of foundation engineering piles is 273 in total, and the tower pile is 50 ultra-deep rock-socketed piles (4 φ 1500 mm, 4 roots φ 1600 mm, 21 φ 1800 mm, 21 φ 2000 mm). Among them & phi; The maximum hole forming depth of the 2000mm large-diameter pile is 112m, and the design requires 4.0 m of weathered granite. Shenzhen industrial exploration group adopts the internationally advanced borne-bg 46 Rotary Drilling Rig imported from Germany to directly form holes and piles, which is extremely difficult and rare in the industry.
The project is located in the reclamation area of shenzhen, and the site geology is quite complicated. There are many high-rise buildings around the project, and the pile depth is large, the rock-socketed depth is deep, the diameter is large, and there are many uncontrollable factors, so the construction difficulty is very high.
Shenzhen work geotechnical group co., LTD. To undertake the project, shall be organized company expert Dr Technology backbone to research and demonstrate, at the same time assemble their own equipment, 46 German Bauer BG BG 38 in the construction, the number is useful - 20-14 # of rock-socketed pile, a diameter of 2000 mm, from opening in the morning, on October 27, weathered granite in the rockface 108.3 meters, to November 1, hole, hole depth of 112.6 meters, rock-socketed 4.3 meters, the total take six days. Due to the fact that the project is located in a busy area, the effective working time of the drilling rig is only 10 hours per day, and a large diameter and large depth rock-socketed pile is completed within 60 hours, which fully reflects the efficient performance and reliable stability of bao e equipment, and also provides an engineering exploration plan for the pile foundation industry to solve the problem of super-large and ultra-deep pile into rock.
Shenzhen shenzheng group is Bauer company close strategic partnership, the two sides to jointly promote infrastructure construction, the new technology and new construction methods and overcoming difficult formation of construction, the project's BG 46 for 2017 introduction of Bauer imported large rotating drill, the machine USES the rated power of 570 kw carter C 18 engine, dynamic, in the process of talents apartment project pile foundation construction, through the two root pile, the average fuel consumption of only 45.1 liters/hour. The torque of BG 46 power head reaches 46 tons of meters, which is obviously advantageous in pile foundation construction under some complicated working conditions. Since it was put into operation in February 2017, this borne-bg 46 Rotary Drilling Rig has been specially used to overcome hard and difficult strata. Under the conditions of ultra-deep, large diameter, large range of hard rock, multi-layer karst caves and high vertical requirements, it has fully demonstrated its super rock-entering ability and stable and reliable technical performance. In addition, BG 46 has high fuel economy and unique advantages in operation cost. Below is a bowe BG 46 rotary drill in operation.
Shenzhen worker group is the domestic first batch shall be adapted from hydrogeological units engaged in survey and design and geotechnical engineering professional company, in nearly 30 years of development, shenzhen working group shall be passing on hydrogeological units of blood, steadily developed into the domestic complete qualification, geotechnical survey and design industry leading technology of state-level high-tech enterprises. At present, there are more than ten sets of international leading equipment such as double wheel groove Milling Machine, rotary drilling machine, continuous wall grab, etc. Industrial exploration group inherits “ Harmonious development between man and nature ” Mission, the pursuit of quality and safety common development, shaping a number of quality projects.
