China Construction Machinery Information

on June 25, with the last explosion, after 54 months of construction, the right line of Micangshan tunnel of Bashan expressway connecting Sichuan and Shaanxi was successfully connected

eight authoritative media, including CCTV, Xinhua news agency, China economic news and China industry news, made in-depth and detailed reports on the incident

CCTV reported that

this tunnel passes through the Micang ancient road of "Xiao He chasing Han Xin under the moon" more than 2000 years ago, and its connection has laid the foundation for the opening of the whole line of the Bashan Shaanxi Expressway by the end of this year and the opening of a new channel into Sichuan

Micangshan tunnel is located at the junction of Hanzhong City, Shaanxi Province and Bazhong City, Sichuan Province. With a total length of 13.81 kilometers, Micangshan tunnel is the third longest highway tunnel in the world, the second longest in China and the first longest highway tunnel in Sichuan. For thousands of years, fenggao road insurance, some of which are for safety, must carry out sequential control of equipment. Micang mountain is an important channel that Sichuan Shaanxi exchanges cannot bypass. With the construction of Micangshan tunnel, this barrier has been completely broken, and the crossing of Micangshan will be shortened from 4 hours to half an hour

"Sichuan Road is difficult" has brought great challenges to the construction personnel. The construction of Micangshan tunnel encountered problems such as high ground pressure stress, high ground temperature and high concentration of harmful gases. Micangshan tunnel passes through the rare high pressure stress hard brittle rock mass, and the risk of rock burst, fault, cracking and even collapse is much higher than that of ordinary tunnels, which requires 24-hour close monitoring. In addition, toxic and harmful gases such as gas and hydrogen sulfide were also found during tunnel excavation, and the construction personnel need to wear gas masks to work

in order to solve the construction problems and speed up the project progress, the project has vigorously promoted mechanized construction since it entered the site. As a leading supplier of complete sets of equipment for tunnel construction in China, two three arm rock drilling jumbos produced by XCMG Tiezhuang have successively entered the project Department of China Railway First Bureau in Micangshan tunnel to participate in tunnel excavation construction

surprisingly, despite maintaining high-intensity and high load equipment operation, XCMG Tiezhuang rock drilling jumbo still ensured the smooth progress of tunnel construction with excellent product quality, high construction efficiency, stable performance and nanny after-sales service, and won the full affirmation of the contractor

after the completion of the Pakistan Shaanxi Expressway in the past few years, it will become the third Expressway out of Sichuan in the north after the high price of Guangzhou Shaanxi Expressway and Dazhou Shaanxi Expressway. Shaanxi Shaanxi Expressway radiates the Qinling Bashan mountain area, a national poverty alleviation area. With the help of XCMG equipment, it is of great significance to drive the economic development along the line and promote poverty alleviation

XCMG will continue to uphold the core values of "taking on great responsibilities, walking the road and becoming a great thing", practice the gold standard of "leading technology and indestructible" action, and advance towards high-end and world-class brands. At the same time, XCMG will continue to help the construction of various infrastructure in the motherland, and use the weight of the country that drives the progress of the equipment industry to forge the great "Chinese dream" and "XCMG dream"
