HF-6A Percussion type borehole drilling rig for piling foundation
1.Simple Description of borehole drilling rig:
1>Percussion type piling rig is one important drilling equipment in foundation construction of pile and
borehole.It can adopt to various geological conditions,especially to pebble bed and rock stratum.
Percussion drilling rig is more applicable than the other kinds of drilling machines.Meanwhile,when
use the percussion drilling rig to drill boreholes,after the hole is formed,there will be a dense layer of
soil around the hole wall,which is very useful for stabilizing the hold wall and improving the carrying
capacity of the pile foundation.
2>HF-6A borehole drilling rig is very popular in the market currently,all of its components are all installed in
the trailer,like electric motor,drive motor,hoist,mast etc,integrate motion. The percussion drilling rig uses
the crank-link mechanism to change the power's gyration motion into alternating motion ,through
the steel wire rope to drive the hammer bit to do up-and-down motion.With the impact effect of
the hammer bit's free failing,to break the soil,sand,pebble or rock into pieces,and then use the
slag tube or mud pump to clean the slag our of the hole.
