The proportion of tunnel projects in the transportation network is increasing, and with complex geological conditions and construction environments, the construction of tunnel projects is growing in both quantity and strictness of construction requirements. In order to fundamentally improve the construction of tunnel projects in our country, it is necessary to achieve mechanization in tunnel construction. The integration of mechanization with construction techniques and construction processes is an inevitable trend in the development of tunnel projects.

Our company has accumulated years of experience in gas expansion construction in hard rock conditions and has developed specialized techniques for tunnel excavation projects that involve hard rock and cannot use explosives. These techniques ensure project progress while protecting the environment, minimizing the impact on natural ecosystems caused by tunnel and underground construction.

The combination of mechanization and specialization in construction addresses the need to replace manual operations as the main approach, ensuring safety and quality, and resolving labor-intensive work patterns.
