Scew Rotary Auger Drilling Machine generally adopts hydraulic crawler type telescopic chassis, self-retracting collapsible drill collar, telescopic Drill Pipe, automatic detection and adjustment of verticality, digital display of hole depth, etc. The orotary auger Drilling Machine operation generally adopts hydraulic pilot control and load sensing. The rotarry drilling rig is light and comfortable to operate. The main and auxiliary hoisting can be applied to the needs of various situations on the construction site. This type of drilling rig is suitable for different Drilling Tools and is suitable for the drilling of dry (short spiral) or wet (rotary bucket) and rock (core drilling). It can also be equipped with long auger, underground continuous wall grab and vibratory hammer. Etc., to achieve a variety of functions, wheeled auger drilling machine mainly used for municipal construction, highway bridges, industrial and civil construction, underground continuous wall, water conservancy, anti-seepage slope protection and other basic construction. Domestic experts believe that rotary drilling rigs still have a large market in China in the next few years.
Advantage of Rotary auger Drilling Machine:
1. Advanced mobile type, quick to transfer from transportation to working mode.
2. High safety standard, satisfying dynamic and static stability requirements, ensuring safe working
3. Optimized luffing mechanism, working stable, easy to maintenance.

Kindly be informed that :
(1) The perpendicularity of the hole formation in the soil layer and the installation of the steel casing has a great influence on the verticality of the pile;
(2) The concrete casing for positioning and the steel casing are used in a reasonable manner, which can effectively shorten the positioning time of the drilling rig and improve the construction efficiency;
(3) Rotary buckets are used to make holes in soft rock and soil layer once; in hard rock, a spiral drill bit is used to make small holes, and then the rotary bucket is used to expand and expand into holes.
