GY-60/80 Hydraulic or Pneumatic DTH Hammer Impact Anchor Drill Rig
Aplication:
Hydraulic or Pneumatic DTH Hammer Impact Anchor Drill Rig
They are full hydraulic anchoring machines, it is used for supporting and protecting basic/medium pits, ensuring displacement of buildings, and avoiding geological hazard. It can move fast with the crawler, automatically disassemble rods and casing, reducing labour works and improving efficiency.
Short Introduction
GY-60 (GY-80) crawler type full hydraulic engineering anchor drill rig is used for embankment reinforcement of industrial construction such as railways, highways, bridges, roadbeds, dam foundations, etc., and foundation strenghting of civil buildings such as water-proof and leak-proofing works, soft foundation treatment, and geological disasters control and the anchorage aginst the building displacement.
Carried out with PDC bits,it can be rotary drilling in rock layers.
In the rock layer, with the sphierial crown button drill bit,it can be drilling hole at high speed.
On pebble layers,matching with following pipe drilling tools,it meets casing drill.
Equipped with hydraulic impact system,it can meet the foundation constructionworks such as impacting and breaking rock and hole formation, fluid discharge, underground micro-pile, drilling for roof bolt or anchor cable, geological prospecting, geothermal hole formation and slope supporting.
After changing power head,it has rotary jet grouting funtion(swing jet grouting, fixed jet grouting),which can also carry out advanced pipe-shed supporting and geologic forcasting in the tunneling.
