2019 New Designed Horizontal Earth Boring Machine
Applications And Features :
Perforation diameter : 70mm-125mm.
The maximum perforation length is : 30M.
The best working medium is : natural soil with moderate water content.
The available working medium : railway subgrade,highway subgrade and the natural soil layer.
Working Principle :
1. The working principle is like the air hammer,compressed air is provided by the air compressor, the impact piston in the machine does reciprocating motion under the action of compressed air.
2. The puncher through all the compressible soil forms a tunnel,the required laying pipe is tracted to the tunnel,in this case,traffic is not interrupted,the road is not damaged,this kind of extrusion perforation is the least damage to the road subgrade.
3. DH series underground punch has no recoil,no need to support,construction excavation space is small,equipment maintenance is convenient,simple operation,power equipment is not placed in the working pit,low labor cost (1-3 person) can operate.
