Safety Hazard Control Case in Earthmoving Machinery Construction
Earthwork excavation is an important part of civil construction, which involves the process of mechanical and manual coordination, and there are many safety risks.
Hidden danger case 1 - Hidden danger management case of earthmoving operation
Hidden danger name: mining machinery and construction personnel work at the same time
Hidden danger
1. During earthwork excavation, within the working radius of the excavator, ground personnel are engaged in bottom clearing, leveling and slope repair operations, which may cause the following dangers to personnel:
First, when the grab operates, due to the large volume, the operation will make debris such as gravel and silt splash out instantly, and it will be dangerous if there are personnel standing next to the grab.
Second, when the machine moves, whether it is moving forward and backward in leveling the road, or turning around when handling equipment, it is necessary to ensure that there are no people around the machine. When the machine moves, there will be a lot of inertia, and once there is an emergency, it will cause great danger to the construction personnel.
2. No safety warning signs, warning lines and night warning signs are placed in the working area of mining machinery.
Hidden danger rectification
1. Before the construction of the excavator, the construction area shall be inspected for safety, including geological conditions, regional stability and surrounding environment. A scientific and reasonable construction plan shall be formulated according to the inspection results.
2. Conduct safety disclosure to the construction team, do safety education and training, so that the construction personnel can understand the risk of the site, master emergency treatment measures, and improve safety awareness and response ability.
3. Check whether the operator is licensed, ensure that they have driving skills and safety awareness, pay attention to safety management and strictly implement safety regulations.
4. Set up obvious warning signs at the entrance of the excavator construction site and in the dangerous area to warn construction workers and outsiders to pay attention to safety.
5. Do a good job of hazard prevention, in high slopes, steep slopes, deep pits and other dangerous areas, set protective railings, install warning lights, etc., do a good job of safety protection measures.
6. Arrange the safety management personnel to inspect the side stations on the site, and timely deal with the problems found in earthmoving operations to ensure the safety of the construction site.
Hidden danger case II - construction dust hidden danger control case
Hidden danger name: earthmoving operation is not timely sprinkling water to produce a lot of dust
Hidden danger
In the process of earthwork excavation, due to the large site wind speed, dust is blown out through the upper tuyere, and the sand and dust in the air surge:
1, affecting the respiratory health of construction workers. Most of them enter the lungs through the nasal cavity and throat, causing changes in lung function, nervous system diseases, etc., and spread a variety of epidemic diseases through the air, many germs and viruses are attached to the dusty surface.
2, causing particulate matter in the atmosphere will reduce visibility, easy to form smoke and fog, causing serious visual pollution.
Hidden danger rectification
1. Establish sprinkling cleaning and dust suppression system and configure sprinkling equipment. Water and dust removal should be carried out in excavation and transportation areas. Specify the frequency of sprinkling and establish a record ledger, and increase the frequency of sprinkling during heavy pollution weather.
2. Dust reduction measures, such as covering and spraying water curing, must be taken at the construction site for centralized stacking of earth and exposed sites.
3. The earthmoving and muck trucks on the construction site shall be closed and covered for transportation, and it is strictly prohibited to scatter and dump along the road. Construction site set up garbage storage points, centralized storage of construction waste and cover, daily clear.
4. If necessary, provide masks for construction workers at the construction site.
Excavator is a widely used earthmoving construction machinery, mainly used for digging land and transporting materials. It is not only easy to use, but also able to withstand all workloads and help complete various engineering projects.
However, there are also various risks in the construction process of excavators. Taking targeted preventive measures and improving the level of operation can effectively reduce the possibility of accidents. Doing preventive work before construction is often more important than remediating afterwards.
Hidden danger case 3 - excavator safety facilities configuration case
Hidden danger name: The body of the excavator is not pasted with warning signs
Hidden danger
1. No obvious warning mark is set in the mining fuselage, and the warning function cannot be achieved when man-machine cooperation, which is easy to neglect and lead to safety accidents.
2. The excavator is not equipped with fire extinguishing devices
Hidden danger rectification
1. It is forbidden to stand a sign within the turning radius of the body of the excavator.
2. The excavator is equipped with fire extinguishers and other equipment.
Safe construction tips for excavators
1. Check the equipment before operation to ensure that there are no obstacles and personnel, and start the operation after sounding the siren.
2. Digging and eating soil should not be too deep, and the bucket should not be too fierce to avoid damaging the machinery or overturning. Avoid hitting the track and frame when the bucket falls.
3. When working with the excavator personnel within the rotating radius, the excavator should stop rotating if necessary. People on and off the plane should cooperate closely to ensure safety.
4. Vehicles and pedestrians are not allowed within the loading range of the excavator. When unloading, wait for the car to stop and then work. When the driver performs the unloading operation, the bucket is lowered but not allowed to hit the car.
5. When the excavator is rotating, the rotary clutch is used to rotate smoothly with the rotary mechanism brake, and sharp rotation and emergency braking are prohibited.
6. Before the bucket leaves the ground, do not do rotating, walking and other actions; When the full load is suspended in the air, it is not allowed to lift up or down the arm rod or walk.
7. When the excavator is working, it is strictly prohibited to carry out repair, maintenance, fastening and other work. In case of abnormal noise, odor, and excessive temperature rise, it should be stopped immediately for inspection.
