Product uses:

It is a new type of drilling rig used for soft soil foundation reinforcement. It can adapt to various foundation conditions, achieve the purpose of foundation reinforcement and improvement, improve the bearing capacity of foundation and support slope or underground engineering. Widely used in railway, highway, port, municipal engineering, industrial and civilian building reinforcement projects.

Product characteristics:

1. The rig is mechanical transmission, easy to operate and reliable.

2. Hydraulic walking is adopted to move longitudinally and horizontally. It is convenient to locate the hole and has strong maneuverability, so it is suitable for the requirement of construction technology.

3. In the depth of reinforcement, the drill pipe can be continuously drilled or lifted without dismantling and connecting the drill pipe, so the work efficiency is high.

4. Chain plus pressure relief mechanism is adopted, and there are three kinds of lifting, feeding and rotating speed to adapt to different formations.

5. The derrick adopts multi-stage assembly, lifting tower and dropping tower at the scene.

6. The drilling rig is simple and compact in structure, easy to assemble, disassemble and transport by building blocks, flexible in operation and reliable in use.
