Underground Tunnel Support Equipment

Tunnel drilling rig is a fully hydraulic specialized drilling equipment developed for the narrow space of underground tunnels, widely used in highway, railway tunnels, water conservancy tunnels, mining tunnels, underground pipe galleries and other projects. The equipment mainly completes drilling operations such as advanced pipe sheds, anchor rods and cables, advanced boreholes, grouting reinforcement, and blasting holes, and is the core construction equipment for tunnel surrounding rock support and disaster prevention and control. The whole machine adopts a narrow tracked chassis, which is suitable for the narrow working environment inside the tunnel. The drilling arm can rotate and adjust from multiple angles, achieving seamless drilling of the arch, side walls, and bottom plate without the need for scaffolding to complete high-level drilling operations. Equipped with a high torque hydraulic power head, it can adapt to various processes such as down the hole, rotary drilling, and pipe following drilling. It can be used for stable construction in soft rock, fractured surrounding rock, and hard rock formations, effectively solving the problems of hole collapse and stuck drilling.

Tunnel Drilling Machine
Wheeled dual arm tunnel drilling rig

Wheeled dual arm tunnel drilling rig (dual arm rock drilling trolley) is a fully hydraulic rock drilling equipment developed for underground engineering of medium and large section tunnels. It adopts an articulated wheeled chassis and independent operation of the dual drilling arms. It is widely used in the construction of blasting holes, cutting holes, anchor bolt holes, and advanced exploration holes in highway, railway tunnels, water conservancy tunnels, and mining tunnels.

Jining Tongzhao Machinery was established in 2014, rooted in the Jining Engineering Machinery Industry Belt in Shandong Province. In the early days, its main products were slope protection anchoring drilling machines, photovoltaic pile drivers, and guardrail pile drivers. Relying on local processing and manufacturing foundations, it gradually entered the underground drilling machine track of tunnels. After four stages of technical accumulation, product iteration, scene cultivation, and intelligent upgrading, it has grown into a professional manufacturer of tunnel support drilling machines in China

With the increasing number of medium and large section tunnel projects, Tongzhao Machinery has expanded its product line by developing a wheeled dual arm tunnel drilling rig (dual arm rock drilling trolley) based on a single arm tracked tunnel drilling rig. The dual arm drilling rig is independently controlled, taking into account the synchronous construction of blasting holes and anchor holes. The wheeled chassis has a fast transition speed inside the tunnel, greatly improving the efficiency of tunnel drilling and blasting construction.

Tongzhao Machinery started in 2014, relying on the technology of anchoring drilling machines, and officially laid out in the field of tunnel drilling machines. After 2018, narrow body tracked tunnel drilling machines were launched to overcome the difficulty of entering small section tunnels; Subsequently, we will expand the use of split type and wheeled dual arm tunnel drilling machines, construct a complete product matrix, and adapt to various types of construction such as anchor rods, pipe sheds, blasting holes, and advanced exploration holes.
