According to the Voice of China, "Central News" reported that this morning the diameter of 15.03 meters of mud and water balance shield machine will be in Zhengzhou, Henan, China Railway equipment shield assembly plant officially off the assembly line, which is so far our own design and manufacture of the largest diameter of the mud Balance shield machine.
This equipment will be applied to the Shantou Bay Tunnel project, its success off the assembly line to break the foreign brand over the years unified large diameter shield of the situation.This equipment for our shield procurement cost savings of nearly 100 million yuan, but also marks the China's shield machine design and manufacturing towards high-end, is to fully seize the commanding heights of the world's road boring machine technology.
The large diameter muddy water balance shield machine has the advantages of small influence on the surrounding environment, high degree of factory operation, high precision of ground settlement control, safe and fast. It has a unique advantage in the construction of a cross-river crossing sea tunnel in China. 2025 'planning focus on the development of high-end equipment.
Previously, the core technology of the large diameter mudshield balance shield machine has been monopolized by a small number of developed countries, in order to change this subject to the situation, China Railway Equipment Organization R & D team to break through a number of core technology, this device sets a high pressure Capacity system integration design, atmospheric pressure knife cutter technology, telescopic swing main drive technology, double gas pressure control technology, the degree of intelligent five high innovation, to fill the domestic large diameter mud on the balance of the development of the blank machine blank.
In addition, the shield machine can be tunnels tunneling, soil transport, pipe assembly as a whole, with a high degree of automation, construction safety, without prejudice to navigation, from climate and other advantages.
As an important channel connecting Shantou north and south sides, the Suyue Bay Crossing Tunnel is the most comprehensive large-diameter shield tunneling tunnel.
