At present, rotary drilling rigs have been widely used in foundation construction projects such as municipal construction, highway bridges, and high-rise buildings. The efficiency and completion of its hole-making operations are one of the factors that have led to its widespread use. Of course, you must be careful when choosing a rotary drilling rig. Different rotary drilling rigs are suitable for different places. Choosing the right one will be better and can achieve twice the result with half the effort. In addition to choosing a rotary drilling rig based on geology, how can you tell which type of rotary drilling rig is suitable for which construction site? The following Shandong Liqiang Rotary Drilling Rig editor will answer for you. Rotary drilling rigs can be divided into three types according to their main working parameters: torque, engine power, drilling diameter, drilling depth and the quality of the entire drilling rig:#road drilling machine#
1. Small machine#road drilling machine#
Torque 100kN·m. Engine power 170kW, drilling diameter 0.5~1m, drilling depth about 40m, and the total weight of the drilling rig is about 40t. The application market positioning of the small machine:
(1) Slope protection piles of various building blocks;
(2) Partial load-bearing structural piles of buildings;
(3) Various piles with a diameter of less than 1m in urban renovation and municipal projects;
(4) Piles suitable for other purposes. The market workload coverage ratio of the small machine reaches more than 30%.
2. Medium machine
Torque 180kN·m, engine power 200kW, drilling diameter 0.8~1.8m, drilling depth about 60m, and the total weight of the drilling rig is about 65t. The application market positioning of the medium machine:
(1) Bridge piles of various highways, railways and other transportation facilities;
(2) Load-bearing structural piles of large buildings and port terminals;
(3) Bridge piles of urban viaducts;
(4) Other applicable piles. The market workload coverage ratio of medium-sized machines has reached more than 90%.
III. Large-scale machines
Torque 240kN·m, engine power 300kW, drilling diameter 1~2.5m, drilling depth 80m. The total weight of the drilling rig is more than 100t. The application market positioning of large-scale machines is:
(1) Extra-large bridge piles of various highways and railway bridges;
(2) Special structural load-bearing foundation piles of other large buildings. The market workload coverage ratio of large-scale machines has reached more than 10%.
These are just for reference, but the specific situation should also be analyzed specifically. The data is only a reference standard.
