Guangzhou Hairuike Tunnel Machinery Co., Ltd., located in Huangge Industrial Park, Nansha District, Guangzhou, is a joint venture company composed of German Heiruike Group and Guangzhou Guangzhong Group. It is also a leader in shield machine production.
At the beginning of 2018, after knowing the construction information of related projects, the Sales Department of our company followed up in time and formed a service team including skills, marketing and production personnel to deepen the docking with customers. According to the cutter head planning, pressure withstanding ability and functional requirements of shield machine, we selected the suitable wear-resistant steel for the manufacture of cutter head and the high-strength steel for the shield machine body, and rooted it. According to the customer's request, we should adopt the improvement method in time and register the green channel in the production link together. According to the working condition, the required physical and mechanical characteristics of wear-resistant steel used in the tool head, the scientific and technological part plans the composition of steel plate rationally, and gives full play to the ensuring role of rolling and heat treatment equipment, so as to produce the products with high strength, high hardness and high wear resistance, and finally is satisfied. The demand of high-end customers.
It is reported that the tunneling shield machine is named "Yellow River" with a total length of 166 meters, a total weight of 4000 tons, a total installed power of 8688 kilowatts, and a maximum thrust of 199504 kilobulls. The diameter of the cutter head is equivalent to 5 stories high. The center of the main drive of the cutter head is 14 frequency conversion motors with a total power of 4900 kW.
Jinan Yellow River Tunnel Project is located on the central axis of Jinan city, with Queshan in the north and Jibei sub-center in the South and Jilu Road in the south. The tunnel length is 4760 meters. The shield section is 2519.2 meters in length, the outer diameter of segments is 15.2 meters and the inner diameter is 13.9 meters. It is planned to be double-tube and double-deck, with the upper level being a two-way six-lane highway and the grass-roots level being reserved for urban rail transit.
Jinan Yellow River Tunnel Project, known as the "First Tunnel of the Wanli Yellow River", has initially carried out shield tunneling construction. Tunnel excavation diameter of 15.76 meters, for the world's largest diameter of public rail joint construction shield tunnel. Tunnel excavation is carried out by the "Yellow River" super-large diameter slurry balance shield machine produced by Guangzhou Hairuike Tunnel Machinery Co., Ltd. and 1100 tons of high-quality high-strength steel and wear-resistant steel plate produced by Hegang Wugang Co., Ltd. are used to manufacture the cutter head and body of the shield machine.
