Impact rigs can adapt to various geological conditions. Impact rigs are an important drilling machine for the construction of grouting piles. Especially in drilling in the pebble layer, the impact rig is more adaptable than other types of rigs. At the same time, the hole is made by an impact drill. After the hole is formed, a dense layer of soil is formed around the hole wall, which has a certain effect on stabilizing the hole wall and anchoring the rig to improve the bearing capacity of the pile foundation. The commonly used impact drilling rigs have all the components of the CZ series mounted on trailers. Overall traction. Punching machine drilling is the use of the drill's crank connecting rod mechanism, the power of the rotary motion is changed to reciprocating motion, driven by the wire rope hammer up and down movement. The pebbles or rocks are crushed by the impact of the free fall of the hammer, and the drilling slag is discharged with the mud (or with a slag drum).
