"Today we released 8 brand-new underground engineering'super equipment', many of which are the first in the industry and the world's leading. As a leading enterprise in underground engineering equipment, it demonstrates its strong R&D capabilities.” On January 7, 2022, Sunward Intelligent Chairman and Chief Expert He Qinghua said at the global release of “Innovation Leading the World” Sunward Intelligent Underground Engineering Equipment.

Facilitate the construction of super projects

At the press conference, Sunward Intelligent independently developed two "world's best" products-the world's largest rotary drilling rig, the world's highest fully hydraulic crawler pile frame, and two "world's first" products-pilot hole static pressure Pile machines and large-diameter pile-planting drills have attracted everyone's attention.

"This is our SWDM1280 rotary drilling rig, with a maximum output torque of 1280kN.m and a maximum walking weight of 470 tons, equivalent to nearly 400 cars. It is currently the world's largest rotary drilling rig with a tonnage." As the equipment explains With the introduction of personnel, a super equipment came into view.

This super rotary digging machine is specially designed for super engineering. The mast height of the whole machine can reach 40 meters, the maximum drilling diameter can reach 7 meters, and the drilling depth exceeds 170 meters. It can meet the requirements of super large diameter deep hole embedded rock. It can be applied to the pile foundation construction of sea-crossing bridges and other projects.

"That is our SWCH980-260M full hydraulic crawler pile frame, with a mast height of 62 meters, which is nearly 7 meters higher than similar products in the industry and the highest in the world." Opposite this super rotary digging, an ultra-high pile frame stands proudly. , It will be applied to large-scale construction projects in South Korea.

"There is also the SWPD280 large-diameter pile planting rig, which can implant precast piles with a maximum diameter of 1.2 meters, a drilling depth of 35 meters, and a longest single-section pile implantation length of 18 meters." There is no mature special equipment for the implantation of diameter precast piles. The construction efficiency is low and manual high-altitude operations are required. The high-efficiency implantation equipment for large-diameter precast piles developed by Sunward Intelligent is expected to break through the technical bottleneck of large-diameter precast pile construction and lead Industry development.

In addition, the ZYJ1260BK pilot-hole static pile driver developed by Sunward Intelligent, which organically combines the static pile driver and the rotary drilling rig, is called "a revolutionary product for precast pile construction", and can construct large diameter pipe piles up to 1000mm. , The maximum pilot hole depth is 40m, and the maximum pile tonnage reaches 1,260 tons, which are the highest in the industry. It can be widely used in pile foundation construction for large bridges, ports, major water conservancy projects, and ultra-high buildings.

In addition to these "world's most" and "world's first" super equipment, Sunward has also launched four new products, including two-wheel milling machine, hydraulic piling machine, The underground diaphragm wall hydraulic grab and the full-rotation full set of pipe drilling rigs have achieved full coverage of basic construction equipment categories. Among them, the double-wheel slot milling machine, known as the "luxury" of the pile foundation engineering machinery family, not only has high construction accuracy and efficiency, has low environmental impact and pollution, but also has advanced technology and is difficult to develop. Its successful development fully demonstrates Sunward's strong research and development capabilities.

At the same time, Sunward Intelligent’s self-developed complete set of green and smart mining equipment products-SWDE165I5G+ intelligent drilling rig and "Star of Large Aperture Blasting Hole Drilling" SWDRT250 Fully Hydraulic Cone Drilling rig also made a wonderful appearance at the press conference, and all advanced technologies This time was affirmed by the guests present.

Solving industry problems

As super high-rise buildings, long bridges, high-speed and high-speed railways and other superstructures become larger and larger, pile foundations continue to develop in the direction of large diameters and deep holes. Coupled with higher standards of environmental protection requirements, the efficiency of equipment construction is proposed A greater challenge. The large-scale and intelligentization of basic construction equipment has become an industry trend, which further puts forward higher requirements on the stability, convenience and control performance of the equipment.

Super equipment is used in super projects. During the construction of ultra-deep and large-diameter hard rock drilling, due to the large transient load and the existence of component assembly gaps, the whole machine will shake violently, and even the drilling will be deflected, which will affect the pile foundation. Bearing capacity. In response to the stability problem of this large-scale foundation construction equipment, Sunward invented the "large inertia slewing brake and auxiliary vehicle stabilization device", "super-large chassis and sliding shoe auxiliary vehicle stabilization technology", and "column adaptive bending moment balancing technology". The industry’s original and advanced technologies such as "double diagonal bracing triangle support structure and control technology" enable these super equipment to deal with complex environments and complex stratum ultra-deep, ultra-large, and ultra-hard pile foundation construction, not only in the scope of operation, construction efficiency, etc. It has significant advantages in terms of operation stability, reliability, and quality of hole formation and pile formation.

In order to solve the problems of overweight, ultra-wide, ultra-high and difficult on-site disassembly and assembly during the transportation of ultra-large equipment, Sunward Intelligent has developed "fast separation of getting on and off and transportation of the whole machine" and "self-loading and self-unloading crawler chassis technology" to achieve The quick disassembly and assembly of the chassis, as well as the quick disassembly and assembly of the chassis and the loading platform, simplifies the disassembly, installation and transportation process, and doubles the average operating efficiency.

At the same time, Sunward Intelligent has also created Sunward Xiangyun Industrial Internet Platform, which can monitor and record pile position data, drilling parameters, equipment status and project progress in real time, realize intelligent recording and management of equipment and construction, and realize full life cycle management And the extension of the user value chain. In addition, for complex and dangerous working conditions, through the highly telepresence 5G remote control simulation platform, operators can perform remote real-time operations thousands of kilometers away to ensure the safety of operators and equipment.

Sunward Intelligent is also constantly seeking breakthroughs in construction methods. Take the introduction of the pilot hole static pile driver as an example. This equipment innovatively combines the central digging pilot hole and static pressure construction method, avoiding the noise and environmental pollution caused by traditional construction methods, and broadening the high strength The geological application range of prestressed pipe piles, an environmentally friendly pile, has produced good economic and social benefits.
