product Introduction
HFWJ135B tunnel horizontal drilling rig is dedicated equipment for advanced pre-support during the tunnels construction when it encounters weak aquifers like aeolian sand. Through the rotary jetting construction method, a closed rotary jetting pile curtain is formed before tunnel excavation. The jet grouting rig can also be equipped with different drilling tools for slope disaster management, anchoring and other operations.
Features
- 1 Strong drill ability, Wide Application, Long Stroke, Fast Drill Speed, Easy Accidence Handling, High Boring Efficiency.
- 2Drill head is available to change speed by gear or hydraulic. Satisfied with DTH hammer, casing following, casing drilling & carbide rotation and other various drill techniques.
- 3 Patent Design of telescoping system in output shaft will effectively protect drill tools Turn drill head & orifice can extend the drill angle range.
- 4 Machine installed a hydraulic clamping & breakout system in order to automatic wrench the drill pipe and tools. Both assistant time and lobar intensity are reduced during the drill work.
- 5Crawler Chassis with turning platform system, make it easy and rapidly to move and get hole position.To preferably select the parts from domestic and international well known brand products provides HFSF-Series Drill reliable performance and long using life.
- 6In this series, HFSF-Q crawler drilling rig has level system (drill arm) is able to adjust mast in different angle and height without moving drilling rig. Specially for anchoring drilling in deep foundation basis.
- 7Drilling rig is installed with jet grouting device in order to drill enlarge head anchoring work. It is also available for normal simplex, duplex, triplex tube jet grouting drill work.
Application
Dry auger-----Dry soil
DTH Hammer----rock area
Mud casing drill----sand or loosen area
DTH ODEX drill---- gravel or broken rock area
