Information

On November 9, the right line shield machine of Dongguan Metro Line 1 People's Vehicle Interval constructed by China Railway Shanhe was successfully launched, which is the shield machine of China Railway Shanhe following the successful penetration of the line in November last year after the construction of the Daoren Interval, and is of great significance to the overall progress of the project.

It is reported that Dongguan Metro Line 1 is one of the urban backbone lines of the urban rail transportation network in Dongguan City, Guangdong Province, Dongguan is connected to Guangzhou and Shenzhen rail transportation network, an important transportation line, linking the two main urban core clusters in Dongguan City (Guancheng Area, Songshan Lake Area) the development of the main axis.

Dongguan Metro Line 1 of the People's Hospital Station ~ Automobile General Hospital Station, the total length of the right line is 1715.05m, along the line of ground structures are mainly overpasses and commercial residential mainly, greatly increasing the difficulty and risk of excavation.

By China Railway Shanhe technical personnel and construction project parties to discuss and verify the selection of excavation diameter of 6980mm soil pressure balance shield machine, from small mileage to large mileage direction, the tunnel was “V” shaped slope to 26 ‰ uphill start, 27 ‰ uphill reception, plane minimum turning radius of 450m.

“As the tunnel traverses the range of mainly silt, liquefied sand layer and strong (medium) weathering calcareous mudstone layer, the tunnel depth of about 9.67 ~ 24.65m, for this reason, this interval shield machine special addition of double screw conveyor configuration, reduce the frequency of digging slag spurt.” Site personnel introduction.

The smooth start of the right tunnel of Dongguan Metro Line 1 People's Automobile Shield Interval has greatly stimulated the enthusiasm of the project staff, laid a good foundation for the completion of the subsequent node tasks, and provided a solid and powerful guarantee for the full line through.

Next, the project department of China Railway Shanhe will carefully organize, reasonably arrange, emphasize safety, ensure production, grasp quality, create benefits, optimize the group, refine the work process, carry out all the work, make concerted efforts to promote the construction and production, and complete all the construction tasks with high quality and quantity, so as to set up a good image for the company's development in the Guangdong market.
