2. Tunnel equipment: Rock drills or pneumatic drills are usually used in rock tunnels.

3. Loading equipment: commonly used vertical claw rock loader or loader.

4. Transportation equipment: commonly used shuttle harvesters (equipped with vertical claws) and dump trucks (equipped with loaders).

5. Supporting equipment: such as shotcrete machine, anchor machine, jet manipulator, etc.

6. Lining equipment: such as concrete pump and lining trolley. Sometimes there are dangerous stones, support stability monitoring, air quality monitoring, midline control measurement and other equipment. Ground penetrating radar will also be used for long tunnels.

Tunnel construction method:

1, shielding method.

It is a kind of steel movable protective device or movable support, and it is a kind of machinery for building tunnels through weak aquifers, especially river bottom, seabed and urban center. Under its cover, the nose can safely excavate the stratum, and one excavation is equivalent to the width of a circle of assembled lining.

2. Cut and cover. It refers to the construction method of digging the ground, excavating the earthwork from top to bottom to the design elevation, constructing the main structure of the tunnel from bottom to top, and finally backfilling the foundation pit or restoring the ground.

3. Cover excavation method. After digging down from the ground to a certain depth, the top is closed, and the rest of the lower works are constructed under the closed top cover. The main structure can be built forward or backward.

4. Shallow excavation method. Referring to the basic principle of NATM, various auxiliary construction measures are taken to reinforce the surrounding rock during excavation, fully mobilize the self-supporting capacity of the surrounding rock, support immediately after excavation, and form a joint support system with the surrounding rock, which effectively inhibits the excessive deformation of the surrounding rock.
