1. Advance support to ensure safety

Suitable for tunnel construction in soft rock and unconsolidated geological conditions, the tunnel is cut and grouted before excavation to form a concrete arch shell, achieving advanced support of the face and effectively preventing displacement of the strata in all directions, ensuring construction safety.

2. Good control of settlement

Due to the implementation of advanced support for the palm face, surface settlement can be effectively controlled, reducing the impact of construction on ground buildings and adjacent structures.

3. Economically convenient

Compared with shield tunneling equipment, it has the advantages of low price, convenient transportation, easy installation, and low electricity requirements.

4. Large internal space

The equipment adopts an arch style design and can accommodate various tunnel construction equipment inside.

5. Strong operability

The equipment adopts two control methods: manual and remote control. The cab has a large operating space, and the operating system adopts a self-developed intelligent automatic control system.

6. High positioning accuracy

The equipment adopts an automatic navigation system, and the steering and translation adopt a new walking four point steering structure.
