What Are The Advantages of Rotary Drilling RIGS in Rail Transit Projects

The underground construction environment of rail transit projects is complex, and it has extremely high requirements for the quality of pile foundations, construction efficiency and environmental friendliness. Rotary drilling RIGS, with their unique technical features, have become indispensable key equipment in such projects, demonstrating significant advantages in ensuring project quality and progress.

1. Adaptability to diverse geological conditions: Equipped with different types of drilling tools, rotary drilling RIGS can handle various strata such as clay, sand, and rock layers. In the construction of metro tunnel pile foundations, even when encountering isolated rocks or hard rock interlayers, holes can be formed efficiently, reducing the impact of geological restrictions.

2. High pile formation efficiency: Compared with traditional drilling equipment, rotary drilling RIGS have a faster drilling speed, and the time for forming a single pile can be shortened by more than 30%. In the construction of high-speed rail hubs, a large number of pile foundation works can be completed quickly, effectively ensuring the progress of the project.

3. Precise pile quality: Equipped with an intelligent positioning and verticality control system, the verticality error of the hole can be controlled within 1%, and the pile diameter deviation is small. This provides a solid foundation for the structural stability of rail transit projects and reduces potential safety hazards in the later stage.

4. Low construction pollution: Dry method or mud wall protection drilling is adopted to reduce the amount of mud discharged, and the operation noise is relatively low. In the construction of urban subways, it can reduce the impact on the lives and traffic of surrounding residents and meet environmental protection requirements.

5. Strong adaptability to the site: The equipment has a flexible shape and can operate in narrow sites, especially suitable for scenarios with limited construction space in urban rail transit. By adjusting the Angle of the fuselage, the drilling position can be precisely located in complex site layouts.

6. Intelligent operation: Equipped with a digital control system, it can monitor drilling parameters in real time, achieve automatic speed regulation and fault early warning. Operators can grasp the construction status through the display screen, improving the accuracy and safety of the operation.

Conclusion: Rotary drilling RIGS, with their adaptability to complex geological conditions, efficient pile forming capacity, precise construction quality, low environmental impact, flexible site adaptability, and intelligent operation mode, have become ideal equipment in rail transit projects, providing strong support for the efficient, safe, and environmentally friendly construction of rail transit networks.
