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) AKL-A-8A 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.
