Portable Percussion Drilling Rig Rock Soil Sampling Light Power

Rock Soil Sampling Light Power Portable Percussion Drilling Rig

The portable percussion drill is mainly used for sampling silt, cohesive soil, sandy soil, fine gravel soil layer and light dynamic penetration test.
Percussive drill is an important drilling machine in the construction of cast-in-place pile foundation. It can adapt to various geological conditions, especially drilling in pebble layer. Percussive drill is more adaptable than other types of drill. At the same time, the impact drill is used to make holes, and the hole wall is formed into a solid main layer, which plays a certain role in stabilizing the hole wall and improving the bearing capacity of pile foundation.

This impact drill includes motor, transmission motor, hoist and mast, integral traction. Punching machine drilling is to use the crank connecting rod mechanism of the drill, the power of the rotary movement to reciprocating movement, through the wire rope drive hammer up and down movement. By punching white by the impact of falling, the pebble or rock broken, drilling slag with mud (or with a slag Jane > discharge.
They come in a variety of shapes, most of which have a cross blade. Because the drilling of percussion drill is to break the rock into powder slag, the power consumption is great, and the drilling efficiency is very low. As a result, other types of drilling machines have been used in other formations except for drilling in pebble beds.
