When heavy rain pours down in torrents, the raindrops the size of beans pelt the ground densely, instantly forming puddles. The originally solid working area becomes extremely muddy. When the fierce wind roars past, it sweeps up the sand and stones on the ground, as if to sweep away everything - in such bad weather, the operation of the rotary drilling rig is like "dancing on the edge of a knife", full of dangers. Heavy rain causes the soil moisture content to increase sharply, and the soil's bearing capacity to drop significantly. During the operation, the drilling rig is highly prone to sinking; the fierce wind may intensify the shaking of the drill pipe, not only affecting the quality of hole formation, but also potentially causing the drill pipe to break, and even leading to serious accidents such as the collapse of the drilling rig. At the same time, the bad weather will greatly interfere with the operators' vision and operational judgment, increasing the risk of personnel injury. Therefore, in bad weather, the safe operation of the rotary drilling rig is of utmost importance and cannot be compromised in the slightest.
(1) Blind movement, full of dangers
Under the influence of adverse weather conditions, the ground conditions of the work site will undergo significant changes. After continuous heavy rain, the ground will become muddy, and the originally flat site may develop uneven depressions of varying depths, and even form an淤泥 layer in some areas； while in strong wind conditions， the wind may blow debris onto the ground， making it difficult for the operators to determine the actual situation of the ground. If the rotary drilling rig moves blindly under such circumstances， the consequences will be unimaginable. Once， such an accident occurred： At a construction site after the heavy rain， the operators did not conduct a thorough investigation of the site before driving the rotary drilling rig randomly. As a result， the drilling rig got stuck in a mud pit formed by the rainwater erosion， the vehicle was severely tilted， not only causing damage to the drilling rig itself， but also delaying the progress of the entire project and causing huge economic losses. This case deeply warns us that under adverse weather conditions， the rotary drilling rig must not move blindly； it must first conduct a comprehensive and detailed investigation of the ground conditions to confirm safety before moving.
(2) Dangerous areas， do not approach
When the rotary drilling rig is operating or parked under adverse weather conditions， it is essential to stay away from dangerous areas to ensure safety. In the river area during heavy rain， the river water level will rise rapidly， potentially causing floods， resulting in the land being soaked and the bearing capacity decreasing， and parking the drilling rig here is highly likely to be submerged by the flood or overturned due to the ground subsidence. The area near the landslide-prone mountain is even more dangerous； heavy rain will reduce the stability of the mountain soil， and there is a high possibility of a landslide， with huge earth and rocks instantly burying the drilling rig， causing irreparable losses. The area under trees is also not a safe place； strong winds may break the branches， and the fallen branches may hit the drilling rig or the operators； in thunderstorm weather， trees are prone to become lightning targets， approaching the trees will increase the risk of lightning strike to the drilling rig and personnel. In addition， there is a great danger near power lines； strong wind may cause power lines to break or sway， if the drilling rig accidentally touches the power lines， it will cause an electric shock accident， endangering the life safety of the operators.
(3) Forced operation under adverse weather conditions
When encountering winds above level six， continuous heavy rain， thunder and lightning， or heavy fog， forcibly operating the rotary drilling rig is undoubtedly taking risks with life and equipment safety. Winds above level six will cause the drill pipe of the rotary drilling rig to be subjected to strong wind force， the shaking amplitude of the drill pipe will far exceed the normal operation range， not only cannot ensure the verticality and accuracy of the hole formation， but also may cause the drill pipe to bend， break， or even due to the violent shaking of the drill pipe， the entire drilling rig to lose balance and cause a drilling rig overturning accident. Continuous heavy rain will cause the work site to be severely waterlogged， the soil to be muddy， and the drilling rig is prone to sinking during operation， and the rainwater may also seep into the electrical system and hydraulic system of the drilling rig， causing equipment failure. Thunderstorm weather is even more terrifying； the powerful current generated by lightning will instantly burn the electrical equipment and even cause a fire， posing a serious threat to the life safety of the operators. In foggy weather， visibility will be significantly reduced， operators cannot clearly observe the surrounding environment and the operation of the drilling rig， and it is very likely to cause safety accidents due to operational errors.
(1) Before the operation: Thorough inspection to prevent accidents
When conducting rotary drilling machine operations under adverse weather conditions, a thorough inspection before the operation is the first line of defense to ensure safety. First, strictly review the qualifications of the operators to ensure they have the necessary operation certificates and are familiar with the operating procedures of the rotary drilling machine and the precautions for operations in adverse weather conditions. Prohibit unqualified personnel from operating the machine. Secondly, conduct a comprehensive and detailed inspection of the rotary drilling machine, focusing on key parts such as the power system, hydraulic system, and electrical system. Check the engine oil level, water level, and oil pressure of the power system to ensure they are normal and the start-up is smooth. Check the hydraulic oil level and quality, and whether there are leaks or damages in the hydraulic pipelines, and whether the hydraulic components are working normally. Check the line connections for the electrical system to ensure they are firm and there is no aging or damage. Also, ensure the lightning protection device is in good condition and effective. Finally, conduct a detailed investigation of the operation environment to check if the operation site is level, if the drainage system is unobstructed, if there are any water accumulation, potholes, etc., and to understand the direction and depth of underground pipelines, avoiding areas with dense underground pipelines, as well as areas with potential landslide mountains, rivers, high-voltage power lines, etc. Also, pay close attention to the weather forecast and accurately grasp the weather changes to provide a reliable basis for operation planning.
(2) During the operation: Standard operation and constant vigilance
During the operation of the rotary drilling machine, operators must strictly follow the operating procedures, remain vigilant, and closely monitor all situations to ensure the safety of the operation. Operators should concentrate, strictly control the rotation speed, drilling speed, and lifting speed of the drilling machine, and avoid equipment failure or safety accidents due to excessive speed or forceful operation. At the same time, closely monitor the operating status of the drilling machine, listen carefully to the sounds of the equipment operation, and observe the display data of the instruments. If abnormal sounds, vibrations, oil leakage, or electricity leakage are detected, stop the machine immediately for inspection. Once the fault is resolved, continue the operation. During the drilling process, pay attention to the conditions inside the hole, by observing the discharge situation, drilling resistance, etc., to determine if there are any collapse or stuck drill problems. If any abnormalities are detected, take corresponding measures for handling. In addition, operators should control the walking speed of the drilling machine and observe the surrounding environment at all times to avoid obstacles and dangerous areas. At the same time, maintain close cooperation with the command personnel, strictly follow the signals and instructions of the command personnel, and the command personnel should stand in a safe position where the operators can clearly see, and accurately issue instructions to ensure the coordinated and orderly operation of the operation.
(3) After the operation: Proper parking and timely maintenance
After the operation of the rotary drilling machine, proper parking and timely maintenance are important steps to extend the equipment's service life and ensure safe operation in the next time. First, park the drilling machine in a place with higher terrain, solid ground, good drainage, and away from dangerous areas, avoiding parking in low-lying water areas, landslide areas, rivers, and areas near high-voltage power lines. When parking, retract the drill pipe and place it on a stable support to ensure the drill pipe does not shake or tip over due to external force. At the same time, tighten the handbrake of the drilling machine and place triangular blocks to prevent the drilling machine from sliding during parking. Secondly, conduct a comprehensive cleaning of the drilling machine, removing dirt, sand, and other debris from the body, drill pipe, and chassis to prevent debris from entering the equipment and affecting its normal operation. Then, perform timely maintenance, checking whether the power system, hydraulic system, and electrical system components are intact, with no looseness or wear, and replacing worn-out components in time; Add an appropriate amount of lubricating oil to each lubrication point to ensure good lubrication between components; carry out rust prevention treatment, apply rust inhibitor to exposed metal parts to prevent rust caused by adverse weather conditions; inspect the electrical system to ensure secure connections and no aging or damage; add sufficient fuel according to the equipment requirements to prepare for the next operation. If the drilling rig needs to be parked for a long time, in addition to the above maintenance work, the hydraulic oil, coolant, etc. should be drained completely, a comprehensive anti-corrosion treatment should be carried out on the equipment, and the equipment should be covered to prevent it from being eroded by sunlight, rain, dust, etc.
To sum up, when conducting rotary drilling machine operations in adverse weather conditions, one must strictly adhere to the core prohibitions, remember the serious dangers of blindly walking, approaching dangerous areas, and performing forced operations, and at the same time, implement various practical protective measures before, during, and after the operation. Ensure that the safety concept runs through every aspect of the operation. The safety of rotary drilling machine operations not only concerns the life and health of the operators, but also directly affects the progress and quality of the project, and relates to the economic benefits and social reputation of the enterprise. Therefore, every rotary drilling machine operator must always keep safety on a tight leash, keep the principle of "safety first" in mind and put it into practice, continuously improve their safety awareness and operational skills, and ensure that rotary drilling machine operations in adverse weather conditions are safe and orderly, providing a guarantee for the smooth progress of engineering construction.
