2016 New Designed Horizontal Directional Drilling Machine Quality Choice

2016 New Designed Horizontal Directional Drilling Machine :

Applications And Features :

Perforation diameter : 70mm-150mm
.
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.
