XCMG tunnel boring machine appeared on the CCTV topic "Five Years of Progress"

On July 2nd, the CCTV project “Five Years for Progress” focused on the tunnel project, demonstrating that in the past five years, our country’s builders have made great efforts to overcome difficulties and scientific construction, conquering and solving difficult problems in mountainous and difficult geological complex areas. Channels, one by one tunnel project in the indomitable progress of the builders tenacious advance, creating one after another domestic initiative.

Xu is a leader in the domestic tunnel boring machine industry and has worked in numerous major tunnel projects both at home and abroad, leading the industry in green construction. When the film “Guiyang Rail Transit on the Knife Tip” was introduced in 3 minutes and 16 seconds, the shot at the construction site appeared on the XCMG tunnel boring machine.

From 2015 to 2016, during the construction of the Guiyang Railway Station Rail Transit Line 1, there were more than 10 XCMG roadheads working together to promote the construction of the local track. Guiyang is a karst landscape area, with both plateau mountains and hills, basins, river valleys, and terraces. The subway passes through mostly dolomite and limestone. The rock hardness is above 60 MPa, and locally reaches over 90 MPa.

Because the construction needs to pass through important nodes and dense residential areas such as the Guiyang railway station and the railway line, if the excavator and the breaker are used, it is difficult to ensure the efficiency of the completion of the construction task as scheduled. In order to overcome these difficulties in construction technology, speed up the construction progress and ensure the smooth progress of the project, users first introduced the XCMG cantilever boring machine to carry out tunnel cold excavation construction. With the XCMG cantilever heading machine construction, it can push more than 80 meters per month, which is more than four times the original speed, and it has obviously improved in responding to accidents, improving safety factor, and optimizing the working environment of the workers, and won the agreement of the project department. Accredited.

At present, XCMG has formed a series of tunnel boring machines for different types of tunnels. It has been applied to highway tunnels, railway tunnels, subway projects, and water conservancy projects. It has consistently ranked first in the domestic market share and entered Indonesia, Kenya, Tajikistan and other international markets. (This article is from Xugong Foundation Zhang Dan Zhang Hang)
