Key Points of Construction of Rotary Drilling Rig

Rotary drilling rig is the key equipment of drilling in construction, and its construction process involves many points. Accurate grasp of these points can not only ensure the quality of drilling, but also improve construction efficiency and reduce construction risks. Next, give you a detailed introduction to the construction points of rotary drilling rig.

1. Preparation of construction site: Before construction, it is necessary to level the site, remove debris and obstacles, and ensure the smooth parking of the rig. According to the geological survey report, the soft ground is reinforced to avoid the rig tilt and sinking during construction.

2. Equipment commissioning inspection: a comprehensive inspection of rotary drilling rig components, such as power system, hydraulic system, control system, etc., to ensure the normal operation of the equipment. Adjustment of drilling parameters, according to geological conditions preset appropriate speed, pressure, to prepare for construction.

3. Drilling operation specifications: At the beginning of drilling, keep the drill pipe vertical and slowly enter the earth. Uniform control of drilling speed to avoid too fast or too slow. Pay close attention to the instrument data, such as torque, verticality, etc., and adjust the operation in time.

4. Mud management and maintenance: reasonable allocation of mud, control mud gravity, viscosity and other indicators. The mud can protect the wall and carry slag. In the process of drilling, the mud can be replenished and purified in time to ensure its stable performance.

5. Lower the steel cage: After drilling, accurately lower the steel cage. Ensure that the steel cage is accurately positioned and firmly fixed to prevent floating or deflection when concrete is poured.

6. Concrete pouring: When pouring concrete, keep continuous and uniform speed. Control the pouring height, avoid the quality problems such as broken pile and hole, and ensure the concrete density of pile body.

Conclusion: The key points of rotary drilling rig construction run through the whole construction process, from site preparation to the final concrete placement, every step is crucial. Strictly following these key points can effectively improve the construction quality of rotary drilling RIGS, ensure the smooth advancement of engineering projects, and build a solid foundation for the construction of construction infrastructure.
