The step method is the most basic and widely used construction method, and it is also an important means to realize other construction methods. However, the inability to use mechanized operation in the tunnel step method construction has always been a pain point in the construction of the industry.

Innovation is the driving force for Wuxin Tunnel to lead the development of technology. In order to better meet customer needs, Wuxin Tunnel independently developed the first single-boom rock drilling rig in China.

The equipment is tailor-made for the tunnel step method construction. It adopts remote control operation, which reduces the technical dependence on operators, and completely solves the problem that large-scale operations cannot be used for advanced small conduit holes, system bolt holes, and inverted arch excavation. Improve work efficiency and construction quality.

Equipment composition

The equipment is mainly composed of chassis system, hydraulic system, electrical system, water supply system, air supply system, cab, crank drilling system, remote control operation system, hydraulic rock drill and so on.

professional enough

The first crank arm structure in China, which satisfies the step construction method, effectively avoids the collision between the boom and the steps, and is especially suitable for advanced small pipe drilling, bolt drilling and inverted arch excavation operations.

convenient enough

The operation range is large, and the whole-section construction of expressways and railways can be completed without moving the car at one time.

flexible enough

The size of the whole machine is small, the construction in the tunnel is flexible, and it can turn around in the tunnel.

smart enough

Remote control operation, simple and easy to learn, can be used quickly, can observe drilling conditions at close range, and effectively control over-under-digging.
