Today we'll learn about the main features and operational requirements of rotary drilling rigs.#kelly bar construction#
Main Features
1. High mobility, allowing for rapid site relocation.
2. Diverse and lightweight drilling tools, allowing for quick loading and unloading.
3. Adaptable to various geological formations, and faster, approximately 80% faster than impact drills.
4. Minimal environmental pollution, eliminating the need for slag removal.
5. Compatible with various types of piles.
Operating Technical Requirements#kelly bar construction#
Rotary drilling rigs officially entered service in China in 1999. At that time, there were no formal operating licenses required by the state. It was considered a specialized job. Because rotary drilling rigs are used for foundation construction, specifically pile foundations, the drill bit works underground, invisible to the naked eye. The entire operation relies on the onboard computer and the operator's experience. Therefore, the operator's skills are highly demanding. After becoming familiar with rotary drilling operations, the operator must also be familiar with various drilling tools, geological formations, construction techniques, and site turnover. They must know which drilling tools to use for which geological formations and how to propose solutions to any problems encountered during construction. A skilled operator can save up to 10% on fuel and accelerate construction progress.#kelly bar construction#
