At this stage, rotary drilling rigs have been widely used in new piling projects. With the advantages of rotary drilling rigs in piling work, more and more people are gradually looking for rotary drilling rigs. However, many people will easily confuse rotary drilling rigs with other mechanical equipment, such as excavators, rotary drilling rigs, down-the-hole drilling rigs, geological exploration drilling rigs, rotary jet grouting piling machines, horizontal directional drilling rigs, etc, here I will share with you the difference between rotary drilling rig and rotary drilling rig.
1. use is different.
1. Rotary drilling rig: used for drilling rock layers with rock strength index f≤ 6 in open-pit coal mines, and can also drill hard interlayer rocks with f = 7-11. When drilling, increase the rotating torque and shaft working pressure to make the twist drill rotate and walk the knife to exercise, to laser cut the rock.
2. Rotary drilling rig: construction machinery and equipment suitable for hole-forming work in construction foundation engineering projects. The key is suitable for the construction of gravel soil, cohesive soil, silty soil and other soil layers, and is widely used in various foundations and foundation construction sites such as bored piles, continuous walls, and foundation reinforcement.

2. characteristics are different
1. Rotary drilling rig: used for drilling rock layers with rock strength index f≤ 6 in open-pit coal mines, and can also drill hard interlayer rocks with f = 7-11. When drilling, increase the rotating torque and shaft working pressure to make the twist drill rotate and walk the knife to exercise, to laser cut the rock.
2. Rotary drilling rig: hydraulic crawler telescopic chassis, autonomous take-off and landing folding mast, telescopic joint drilling tool, automatic flatness identification and adjustment, depth digital indication, etc. The whole mechanical control generally adopts hydraulic leading control and load sensor, which has the characteristics of light and comfortable actual operation. The two main and auxiliary hoisting machines can be applied to various conditions of the construction site.

3. other levels
1. Move the method is not the same
Some models and specifications of rotary drilling rigs cannot move autonomously, while others are footstep-type automobile chassis that can move autonomously;
Rotary drilling rigs generally use hydraulic crawler telescopic car chassis, which can move autonomously;
2. The available natural environment is different
Rotary drilling rig is mainly used for drilling gun holes for mining and coal mining, and can also be used for drilling anchor cable holes, exploration and drainage outlets, coal bed methane extraction holes and coal roadway irrigation holes;
Rotary drilling rigs are mainly used for the construction of soil layers such as gravel soil, cohesive soil and silty soil, and for the construction of various foundations and foundation projects such as bored piles, continuous walls and foundation reinforcement;

3. The solution for mud is different
Rotary drilling machine mud is side drilling side to create mud, waste slurry more and more;
The mud of rotary drilling rig is made in advance and then drilled. The circulation system is applied, and the more it is used, the less it is used;
4. Model and specification
Rotary drilling rigs are divided into portable hydraulic rotary drilling rigs and slide-type hydraulic rotary drilling rigs according to different driving methods;
Rotary drilling rigs are divided into small servers, medium machines and medium machines according to different output power;
Although only one word apart, but the two are very different. Different mechanical equipment is applied to different industries. This point must be firmly grasped. Random selection of equipment will not only lead to resource consumption but also continue to cause certain damage to engineering projects. Therefore, when selecting equipment for one's own engineering construction site, one must see clearly what one must have, and only when one chooses correctly can one solve engineering projects faster and stronger.
