Tibet guest -- XCMG tunnel excavator

In recent years, XCMG has not only left a footprint abroad, but also traveled north and South in china. No matter whether it is flat or steep, we can see the footprint of xcmg.

Recently, three XTR tunnel boring machines developed by XCMG have entered the construction of Tibet water conservancy project, which opened a new chapter for the construction of tunnel boring machine in Plateau area.

Lalo water conservancy project for small section of diversion tunnel Hainan Bay Tunnel, the length of 5212m, section of gate hole 2.3m * 2.99m, rock shale, sandstone, rock strength is 30 ~ 80MPa. In the construction of XTR4/230 cantilever tunnel boring machine in the past two months, the tunneling speed is 1m/h, the maximum rock breaking hardness is more than 80MPa, which reflects the better comprehensive tunneling performance.

XTR4/230 cantilever tunnel boring machine is a tunnel boring machine specially designed for water conservancy and small section tunnel construction by XCMG foundation. Its narrow body design, compact structure, meet the requirements of small section tunnel construction; equipped with integrated dust removal fan effectively reduce the dust concentration, improve the working environment; independent heat dissipation system, meet the operation requirements of continuous operation under the condition of no water or water shortage.

The construction site is 4400 meters above sea level. The climate is dry and the natural conditions are extremely bad. XCMG technology and service personnel escort the construction for all-weather, and fully interpret the "XCMG 360 degree, all-round value service" brand. The XTR series tunnel boring machine has won the first battle in Tibet, and laid a solid foundation for XCMG to open up the plateau tunnel market.
