The rotary drilling rig plays a crucial role in foundation engineering and is widely used in pile foundation construction and deep pit excavation projects. Due to its complex working environment and high load operations, ensuring the safety of the rotary drilling rig during construction is of utmost importance. The safety of the operation involves not only the safety of the operators but also the equipment and the construction site. Below are the key measures to ensure the safety of the rotary drilling rig during construction.
Regular Training
Operators of the rotary drilling rig must undergo professional training and hold relevant operating certificates. They should be familiar with the rig’s basic structure, working principles, and operational procedures, as well as the correct usage of the hydraulic system, drilling tools, and other components. Regular safety training and emergency drills are essential to ensure safety during operations.
Enhance Safety Awareness
In addition to technical skills training, the safety awareness of the operators is crucial. They should be fully aware of potential safety hazards during the construction process, such as equipment overload, improper operation, and unsafe working environments, and stay alert to take effective measures to prevent accidents.
Pre-Operation Inspection
Before starting each operation, operators must conduct a thorough inspection of the rotary drilling rig, including the hydraulic system, power system, drilling tools, tracks, etc. They should check oil levels, oil quality, and look for leaks in the hydraulic system to ensure that all components are functioning properly. The hydraulic system, being the core system, must be in good working condition, with stable pressure and flow.
Regular Maintenance and Repairs
Regular maintenance and repairs are essential to keep the rotary drilling rig in good condition. This includes changing hydraulic oil, inspecting the electrical system, and cleaning the air filters. Regular maintenance helps extend the equipment's lifespan and prevent accidents caused by equipment failure.
Avoid Operating with Faulty Equipment
If any faults or abnormal operation are detected, the rig should be immediately stopped for inspection and repairs. Never operate the rig while it is malfunctioning, as this could lead to equipment damage or serious accidents.
Set Up Safety Fencing and Warning Signs
The working area of the rotary drilling rig should be clearly marked with safety barriers and warning signs to prevent unauthorized personnel from entering the construction zone. Designated safety pathways should be established, and all personnel entering the site should wear protective gear such as helmets, safety shoes, and earplugs.
Define Roles and Responsibilities
The responsibilities and roles of all personnel on site should be clearly defined. Each worker should understand their safety responsibilities in the area where they work. During operations, there should be a designated person responsible for equipment operation to ensure a safe separation between equipment operation and personnel.
Ensure Ground Stability
The stability of the rotary drilling rig is directly related to the ground conditions. When working on soft soil, loose ground, or areas with high groundwater levels, foundation reinforcement measures should be taken to ensure the rig’s stability and prevent tilting or sinking of the rig.
Control Drilling Pressure and Speed
Drilling pressure and speed directly impact the load and stability of the equipment. Excessive drilling pressure may cause the drill bit to become stuck or the rig to overload, increasing the risk of tipping over. Therefore, operators should adjust the drilling pressure and speed based on the geological conditions to avoid overloading the rig.
Choose the Right Drill Bit
Drill bits should be selected according to the geological conditions. For hard rock layers, alloy or diamond drill bits should be used, while spiral or cutter bits are more suitable for soft soil or sand layers. Using the appropriate drill bit improves drilling efficiency and reduces the risk of jamming.
Stage the Drilling and Advance Gradually
When encountering hard rock or complex layers, operators should avoid advancing too quickly. Gradual drilling reduces the impact on the drill bit, minimizes vibrations, and ensures smooth drilling.
Emergency Plans and Equipment
A detailed emergency plan should be developed for each construction site, and necessary emergency equipment such as fire extinguishers, first aid kits, and backup power supplies should be provided. Operators must be familiar with the emergency procedures to quickly address incidents, minimizing harm to personnel and damage to equipment.
Emergency Measures for Jamming
If a drilling jam occurs, operators should immediately take measures such as reversing the drill bit or reducing the drilling pressure to avoid damaging the equipment or causing the rig to tip over. In case of severe jamming, operations should be halted, and the equipment should be inspected and treated.
Fire Prevention and Electrical Safety
Fire risks are higher in high-temperature or dry environments. Operators should regularly inspect electrical wiring to prevent electrical faults that may lead to fires. Fire extinguishers and other firefighting equipment should be readily available, and fire drills should be regularly conducted.
Ensuring the safety of the rotary drilling rig during construction requires addressing multiple factors, including operator training and safety awareness, equipment inspection and maintenance, construction site safety management, control of operational parameters, and emergency response handling. Implementing these safety measures effectively reduces the risk of accidents, ensuring smooth and safe construction. Safety should always be the top priority in every phase of construction, as only by safeguarding both the equipment and personnel can efficient and sustainable project execution be achieved.
