The Linjin Expressway, also known as the Lin'an to Jinhua Expressway, connects Lin'an, Tonglu, Jiande, Lanxi, Jinhua, and other areas, serving as a new passage for the development of the northern region of Lanxi. It adopts the standard of a two-way four-lane expressway, with a design speed of 100 kilometers per hour and a standard roadbed width of 26 meters, spanning approximately 150 kilometers in total. However, the construction of this highway is no easy task, as it traverses multiple mountainous and hilly areas with complex and varied terrain. Tunnels must pass through mountains, and bridges must span gorges, presenting significant challenges to the construction work.

　　To overcome these difficulties, the construction units have utilized modern technology, such as LanHi's LCG312A intelligent integrated arch frame trolley. This equipment integrates functions such as steel arch installation, welding mesh and connecting bars, excavation surface measurement, and more into one unit. Moreover, it is equipped with a car chassis, providing it with the capability for flexible movement, relocation, and emergency response. Additionally, the equipment is equipped with a three-arm frame, with the middle arm operated remotely and the side arm equipped with a local remote dual operating system. The use of these advanced devices not only reduces labor costs and construction risks but also improves work efficiency, achieving the standardization and industrialization of tunnel arch erection.

　　In the future, the Linjin Expressway will become an important transportation artery for Zhejiang Province and even the Yangtze River Delta region, playing a crucial role in regional integration and development. The completion of the Linjin Expressway will greatly shorten the distance from central and western Zhejiang to Hangzhou, providing strong support for local economic development and transportation convenience. Despite facing many challenges during the construction process, with the aid of modern technology and advanced equipment, people have overcome difficulties, gradually turning this expressway into a reality and bringing new opportunities and vitality to the surrounding areas' development.
