Rotary drilling rig is the core heavy equipment for pile foundation construction of the project. It works mostly in outdoor environment. rainstorm, strong wind, thunder, high temperature, severe cold and other severe weather are likely to cause equipment failure, safety accidents, endanger personnel safety and property safety, and delay the construction progress. Based on the actual outdoor construction of rotary drilling rigs, clarifying the operating taboos of various adverse weather conditions and implementing scientific and standardized protective measures are key to ensuring construction safety, extending equipment service life, and ensuring orderly progress of construction. They are also the core link of engineering safety management.
Rainstorm weather will lead to a sharp increase in soil water content and a decrease in foundation bearing capacity, which will easily lead to risks such as rig overturning, foundation pit collapse, etc. Operation shall be strictly prohibited and well protected. In terms of operating taboos, it is strictly prohibited to work in areas with accumulated water depth exceeding 30cm to avoid the drilling rig getting stuck in mud and overturning; Drilling, lifting drill rods, dismantling components, and other operations are strictly prohibited in the rain to prevent rainwater from entering the drill rods, hydraulic systems, and electrical systems, causing equipment failures; It is strictly prohibited to work within 5 meters of the edge of slopes and foundation pits to avoid the risk of slope collapse and equipment falling caused by rainwater erosion. In terms of protective measures, it is necessary to check the drainage system of the construction site before starting work, excavate drainage ditches in advance, and ensure timely drainage of rainwater; In case of sudden rainstorm during operation, stop the operation immediately, transfer the drilling rig to a safe area with high terrain and smooth drainage, recover the drill pipe, level the body, and cut off the main power supply of the equipment; After rain, it is necessary to comprehensively inspect the equipment circuit, hydraulic pipeline, and verticality of the drill rod, clean up the accumulated water and soil in the drilling bucket, and confirm that the foundation has no settlement and the equipment is not faulty before resuming operations.
When the wind reaches level 6 or above, the stability of the rotary drilling rig during high-altitude operations significantly decreases, and the drill rod is prone to swinging and the machine body is prone to deviation. Therefore, it is necessary to strictly regulate the operation and strengthen protection. Operation taboos include: strictly prohibiting the lifting, installation, and dismantling of drill rods, and avoiding the drill rods from being blown by the wind and colliding with equipment, personnel, or surrounding buildings; It is strictly prohibited to work near obstacles or overhead power lines at high altitude to prevent equipment from rubbing against obstacles or electric shock caused by wind; It is strictly prohibited to start the operation without fixing the machine body, and to prevent displacement and overturning of the drilling rig due to wind force. Protective measures should be taken, including paying attention to weather forecasts before starting work, predicting strong winds in advance, and planning construction progress reasonably; In case of sudden strong winds during the operation, immediately stop the operation, retract all drill rods, lock the body brake device, fix the drilling rig body with cable wind ropes to prevent equipment shaking; After the strong wind, check the deformation of the fixing bolts and drill rods on the drilling rig body, as well as the stability of the connections between various components. After confirming that there are no abnormalities, resume operation.
The rotary drilling rig has a tall body and dense metal components, making it easy to become a target of lightning strikes in thunderstorm weather, causing serious accidents such as electric shock and equipment burning. Outdoor operations must be strictly prohibited and lightning protection measures must be implemented. Clear operating taboos: It is strictly prohibited to operate rotary drilling rigs outdoors during thunderstorms, to come into contact with conductive parts such as equipment metal casings and drill rods, and to perform electrical equipment maintenance, circuit connections, and other operations; It is strictly prohibited to park drilling rigs in open areas or high ground to prevent them from becoming isolated conductors and being struck by lightning. In terms of protective measures, the drilling rig needs to be equipped with qualified lightning protection devices, and the lightning protection grounding resistance should be regularly tested to ensure that the grounding resistance is not greater than 4 Ω and the lightning protection effect is guaranteed; Before the arrival of thunderstorm weather, immediately stop operations, transfer the drilling rig indoors or to a dedicated lightning protection shed, cut off the main power supply of the equipment, and unplug all electrical plugs; After lightning strikes, conduct a comprehensive inspection of the electrical and control systems of the equipment, identify potential hazards such as short circuits and damage, and only restart the equipment after confirming that there are no abnormalities.
In high temperature weather (temperatures exceeding 35 ℃), the hydraulic and electrical systems of rotary drilling rigs are prone to overheating, causing a decrease in the viscosity of lubricating oil and hydraulic oil, leading to operator fatigue and equipment failure and safety accidents. Operation taboos include: strictly prohibiting equipment from operating under overload for a long time, avoiding damage to the engine and hydraulic pump due to overheating, and preventing leakage of hydraulic oil and lubricating oil; It is strictly prohibited to work during equipment cooling system failures (such as insufficient coolant or malfunctioning cooling fans) to prevent equipment overheating and shutdown; Operators are strictly prohibited from working continuously for long periods of time in high-temperature environments to prevent heatstroke. Protective measures need to be implemented. Before operation, check the equipment cooling system, replenish sufficient coolant, clean the dust on the surface of the radiator, and ensure normal heat dissipation; Reasonably arrange rest time during homework, stop the machine every 2-3 hours to cool down, regularly check the hydraulic oil temperature, and stop the machine immediately if it exceeds the specified standard; Equip operators with heatstroke prevention equipment, build temporary sunshades, improve the working environment, and inspect equipment electrical circuits to prevent short circuits caused by high temperature aging.
In severe cold weather (temperatures below -5 ℃), the viscosity of equipment lubricating oil and hydraulic oil increases, making it difficult to start. Pipelines are prone to freezing and cracking, and components are prone to wear. Therefore, it is necessary to strictly regulate the starting operation and take anti freezing protection measures. Operation taboos include: strictly prohibiting direct cold starting of equipment to avoid component wear caused by insufficient lubrication of the engine and hydraulic system; It is strictly prohibited to use open flames to bake equipment pipelines, fuel tanks, and engines to prevent fires and damage to equipment components; It is strictly prohibited to carry out operations without sufficient preheating of the equipment, and to prevent the equipment from experiencing drill pipe fracture and body deformation due to excessive low-temperature stress. In terms of protective measures, before starting work, replace lubricating oil, hydraulic oil, and coolant that are suitable for low-temperature environments, check whether the pipelines are aging or damaged, and provide insulation treatment for exposed pipelines; Before starting the equipment, perform a 10-15 minute preheating operation. After the equipment temperature reaches the specified standard, proceed with drilling, lifting, and other operations; After the homework is completed, promptly drain the accumulated water in the equipment to prevent pipeline freezing and cracking. Park the drilling rig indoors or build an insulation shed to avoid prolonged exposure of the equipment to severe cold environments.
Regardless of the adverse weather conditions, it is necessary to implement universal protective measures, strengthen personnel management and equipment inspections, and build a strong construction safety defense line. Operators must undergo professional training, be familiar with the operating procedures and emergency response procedures for adverse weather conditions, and hold a certificate to work; Safety technical briefing must be conducted before homework, clarifying operating taboos, protective points, and emergency measures; Regularly conduct comprehensive inspections of the rotary drilling rig, focusing on checking the braking system, hydraulic system, electrical system, lightning protection device, and fixed components of the machine body, promptly identifying potential faults and ensuring that the equipment is in good operating condition. At the same time, establish emergency plans for severe weather and equip them with emergency supplies (such as first aid kits, backup power sources, thermal insulation supplies, etc.). In the event of equipment failure or safety accidents, immediately activate the emergency plan and handle them in a timely manner to minimize casualties and property losses.
