What is the drilling machine
And the construction cost is low, but the hole is slow, the working efficiency is low, the construction mud is not smooth, the working pressure is low, the vibration is low, no vibration, the soil is not squeezed;
Rotary (rotary) drilling machine can be used for a variety of geological conditions, all kinds of size pile diameter (aperture) and depth (according to the information, the use of reverse circulation drilling method, the construction examples of more than 200 meters, the maximum diameter of 6m
Drilling diameter of 200 ~ 1200mm, drilling depth of 100 ~ 600m. Rotary (rotary) drilling machine according to the principle of its turntable is divided into forward or reverse.
Engineering rotary drilling machine that is rotary drilling into the hole pile commonly used rotary (rotary) drilling rig, is also a general geological drilling rig.
