‌Rotary drilling rigs are mainly used in the following fields‌:

‌Highway and railway pile foundation construction‌: Rotary drilling rigs are widely used in highway, railway and bridge pile foundation construction due to their high efficiency, low pollution and multiple functions. The hole diameter range is 1000-2500mm, and it is the main machine type in cast-in-place concrete pile construction‌.

‌Civil construction‌: In civil construction‌, rotary drilling rigs are mainly used for foundation construction of small-diameter piles with a diameter of 700-800mm. With the increase of load and the increase of foundation pit depth, construction method support is particularly important. Reasonable organization of construction and selection of suitable drilling tools can improve pile efficiency‌.

‌Water construction‌: In water construction, rotary drilling rigs are used for large pile foundation construction, such as the pile foundation of cross-river and cross-sea bridges. These piles have large diameters, long depths, and complex construction environments, requiring high-configuration drilling rigs to ensure the stability of the hole wall‌.

‌Other foundation projects‌: The rotary drilling rig is also suitable for other foundation projects, such as bored pile projects for foundations of high-rise buildings and municipal construction. Its powerful installed power, output torque and axial pressure enable it to perform well in various soil and geological conditions‌.

The drilling rig is an indispensable and efficient construction equipment in civil construction. Its core role is to realize the rapid excavation and transportation of soil, rock and other materials through the rotating drill rod. In specific application fields, the rotary drilling rig has shown a wide range of applicability. First of all, in foundation engineering, such as foundation excavation, foundation pit excavation, cast-in-place pile construction, etc., the rotary drilling rig can complete them efficiently. Secondly, in the laying of underground pipelines, whether it is municipal, gas or water conservancy, or power pipelines, the rotary drilling rig can improve the construction efficiency and quality. Furthermore, in bridge and tunnel engineering, the rotary drilling rig is used for bridge foundation construction, tunnel opening and wall excavation, effectively shortening the construction period and reducing costs. In addition, in mining engineering, the rotary drilling rig also plays an important role, assisting coal seam mining, tunnel excavation and other operations, and improving mining efficiency and safety. In short, the rotary drilling rig has demonstrated its unique construction advantages in many fields with its high efficiency, high precision and environmental protection, and has become a powerful assistant in modern civil construction.
