Application

HFL-180 full hydraulic top impact rotary track drill is mainly used for tunnel pipe roof support hole and pilot survey hole, urban deep foundation pit anchor hole, grouting reinforcement hole, hydropower station, railway and highway slope large tonnage prestressed anchor hole or drainage hole construction, as well as ground source heat pump hole construction.The construction of small foundation pile hole, hydrologic well hole and blasting hole is also considered.

Features:

1. The top hydraulic impact rotary head imported from Germany with original package is adopted to drill multi-angle and multi-purpose with excellent performance

2. Drilling is extremely fast, 3-5 times faster than a conventional rotary drill

3. There is no need for air compressor and no dust pollution when drilling into rock, gravel and soil sandwiching formation

4.The special casing drilling technology can quickly drill the pipe shed and finish the reinforcement project

5. In complex formations, it is also possible to perform (single pipe + casing) double pipe percussion rotary drilling to maintain the stability of hole wall and facilitate the placement of grouting pipe and anchor cable

6. It is applicable to various drilling techniques, which can effectively solve the problem of hole formation in loose overlying stratum, gravel stratum, broken stratum and silt and sand stratum
