300 million yuan "God grade" shield machine for casting large project
This year, what is the most popular in the machinery industry, it should be the pavement machinery, and the shield machine is also widely developed and applied because of the rise of underground work.
Monkey Island traffic tunnel is the Hengqin island to contact the outside world third roads, also called the Hengqin third channel, is a large municipal engineering project investment and construction of Hengqin new area, the shield tunnel stage is about 1100 meters, the tunnel diameter of 14.5 meters, is divided into two layers and two to 6 Lane tunnel. At the same time, the tunnel is reserved for the long - term railway tramway transformation space, and can effectively solve the problem of pipeline crossing the sea and effectively intensive land resources.
300 million yuan "God grade" shield machine for casting large project
The morning of January 22nd, a large municipal engineering project investment and construction, by the Zhuhai Hengqin new area tunnel shares Shanghai Tunnel Engineering Co. Ltd. - Zhuhai Monkey Island traffic tunnel construction ushered in the key nodes -- "Ren", "the victory of shield originating. So far, Monkey Island traffic tunnel engineering on the freeway construction, the second half of 2017 is expected to be put into use.
As the Hengqin to contact the outside world third important channel, Monkey Island traffic tunnel can be ensured in bad weather conditions, to achieve all-weather Hengqin foreign trade relations, long-term will also work with the South Bay Area Expressway convergence, further radiation Zhuhai city and the Western Bay and Doumen.
After the completion of the opening, Monkey Island traffic tunnel will improve the road network of Zhuhai City, the development of Hengqin tourism, promote the economic development of Zhuhai city plays an important role in promoting.
The shield machine "as the driving task as Ao", for the cost of 300 million yuan, Hengqin building, 14.93 meters in diameter (equivalent to five storeys high), the total length of 125 meters, weighing more than 3200 tons, the total thrust is about 203 thousand kN, the shield of such a large scale, in the whole history of shield tunnel in Southern China area is the first time, it is reported that "Ren Ao" light installation has spent 4 months; after the start, every day will advance to the average speed of 6 meters to 8 meters.
Monkey Island tunnel construction also has positive significance. It is reported that the tunnel is the first super large diameter composite shield tunnel in China, which has wide coverage and high technical difficulty. It has strong pioneering and exemplary role in the industry.
Shield tunnel segment is expected to complete the portal construction work can be sealed before the Spring Festival, the Spring Festival site does not leave, to ensure the project progress and quality of Hengqin third channel. "Ao" successful use will accumulate experience for future development and utilization of urban construction in Zhuhai city and Southern China area and underground space, provide more options.
For more road machinery, welcome to the home of engineering machinery, we will provide you with the best products and services.
