What Kinds of Projects Can Various Rotary Drilling RIGS Undertake

Rotary drilling RIGS play a key role in various projects with their diverse designs and performances. Different types of drilling RIGS, due to their functional characteristics, are suitable for differentiated construction scenarios. The following are typical engineering applications corresponding to various types of rotary drilling RIGS:

1. Small rotary drilling rig: The hole diameter is usually less than 1 meter, suitable for operation in narrow Spaces. It is commonly used in shallow projects such as municipal pipe networks, urban road signal light pile foundations, and the foundations of small and medium-sized buildings, especially with significant advantages in dense urban building complexes.

2. Medium-sized rotary drilling rig: With a hole diameter of 1-2 meters and a drilling depth of 30-80 meters, it has a wide range of applications. It is mainly used for pile foundation projects of high-rise residential and commercial buildings, as well as the foundation construction of small Bridges and culverts in highways and railways, taking into account both efficiency and applicability.

3. Large rotary drilling rig: With a hole diameter exceeding 2 meters and a depth of over 100 meters, it is specially designed for complex geological conditions. It is applicable to deep pile foundation projects such as large Bridges, port terminals, and super high-rise buildings, and can handle hard strata such as pebble layers and rock layers.

4. Crawler rotary drilling rig: It has a low ground contact pressure and strong off-road capability, making it suitable for complex terrains such as mountains and swamps. It is commonly used in open-air operation scenarios such as bridge pile foundations, wind power foundations, and water conservancy projects in the wild, and can adapt to harsh construction environments.

5. Wheeled rotary drilling rig: Flexible in movement and convenient for relocation, suitable for urban roads and linear engineering. It is widely used in the construction of highway guardrail piles, municipal pipeline support piles, etc., and is particularly efficient in municipal projects that require frequent relocation.

6. Core rotary drilling rig: Equipped with a dedicated core drill bit, specializing in rock strata. It is applicable to projects such as mountain tunnel anchoring piles and rock-embedded piles for reservoir dam foundations, and can directly form holes in hard rock layers, reducing auxiliary operations such as blasting.

Conclusion: The engineering application of rotary drilling RIGS is closely related to their performance parameters. From small-scale municipal projects to large-scale infrastructure projects, and from ordinary soil layers to hard rock layers, all types of drilling RIGS can precisely match the demands. Selecting appropriate equipment based on the project scale, geological conditions and site environment is the core prerequisite for ensuring the efficient completion of pile foundation construction.
