Recently, the Wujiawan Tunnel of the Chengdu-Chongqing Central Line High-speed Railway in Lezhi County, which Lanhi participated deeply in the construction, was successfully connected! In the field of tunnel engineering construction, every breakthrough in key nodes demonstrates the power of technological innovation! This milestone is not only the crystallization of the wisdom and sweat of tunnel builders, but also a testimony to the hard-core strength of Lanhi equipment!
The Wujiawan Tunnel is 873 meters long. It is a micro-gas tunnel and a medium-risk tunnel with a gently inclined soft rock floor drum. Its stratum lithology is mudstone intercalated with sandstone, and the surrounding rock level reaches V level, which makes the construction extremely difficult. In order to reduce safety risks and construction period pressure, the entire tunnel is constructed by mechanical excavation and two-way tunneling. Lanhi intelligent tunneling and support integrated unit, multi-functional tunneling machine, intelligent arch anchor integrated trolley, wheeled wet spraying manipulator and other equipment participated in its construction.
Among them, the Lanhi LH150Y intelligent tunneling and support integrated unit shines in tunnel construction. With its integrated design that integrates core functions such as tunneling excavation, erection, anchor construction, grouting, and shotcrete support, it subverts the traditional tunnel construction mode, allowing tunneling, shotcrete support, and slag discharge to achieve parallel operations, greatly improving construction efficiency. A construction cycle can be completed in as fast as 8 hours. It also uses intelligent technology to improve construction safety and successfully overcome the complex geological problems of the Wujiawan Tunnel.
The Lanhi intelligent tunneling and support integrated unit not only shines in the Wujiawan Tunnel on the Chengdu-Chongqing Central Line, but also has a wide range of applicability! It is suitable for the construction of complex engineering scenes such as highway and railway tunnels, municipal engineering, hydropower and water conservancy projects with a width of about 9-18 meters and a height of about 8 meters, to escort project construction.
Lanhi has always driven development with innovation and empowered engineering construction with technology. The completion of the Wujiawan Tunnel on the Chengdu-Chongqing Central Line is another monument in our journey! In the future, we will continue to delve into the innovation of intelligent mechanical equipment for underground engineering, and work hand in hand with our partners to open up a new chapter in underground engineering construction with more advanced equipment and better services
