Rotary drilling rig is a kind of drilling equipment widely used in the field of geotechnical engineering. It can carry out efficient and accurate drilling operations under various geological conditions, and is widely used in pile foundation engineering, underground diaphragm wall, underground pipeline construction and other fields.
The main working principle of a rotary drilling rig is to use its rotary drill bit to cut, crush and excavate the formation to form the desired borehole. During the drilling operation, the drill bit of the rotary drilling rig rotates continuously to increase the cutting and crushing capacity of the formation. At the same time, by applying pressure to the drill bit, the feed rate and depth of the drill bit can be controlled, resulting in precise drilling operations.
The rotary drilling rig is able to drill rock mainly by its drill bit and power head part. The drill bit is the main working part of the rotary drilling rig, it has a sharp cutting edge and strong crushing ability, and it is able to cut and break rock and hard formations with ease. The power head is the driving part of the rotary drilling rig, which is able to provide strong torque and rotational speed, so that the drill bit can cut and crush the formation at a higher speed and with more force.
In geotechnical engineering, rotary drilling rigs have many advantages. First of all, it can complete drilling operations quickly and accurately, improving engineering efficiency. Secondly, the drill bit of the rotary drilling rig can be replaced for different formations, so as to achieve accurate drilling of different formations. In addition, the rotary drilling rig also has the advantages of easy operation, good stability and high safety.
In short, the rotary drilling rig can drill rock mainly by its drill bit and power head part. Through the effective cooperation of these parts, the rotary drilling rig can realize the precise drilling operation of rock and hard formation, and provides an efficient and accurate construction equipment for the field of geotechnical engineering.
