1, technical scheme and light, in the process of demolition equipment volume is big, about 30 meters high, weight about 4 tons, so removed from volume, construction difficulty is high, the hazards control and strict precautions. Based on the project to dismantle to high lamp down
1, technical scheme and process review
dismantle facilities in high lamp 【 Light, generally refers to more than 15 meters steel conical light pole and high-power modular fixtures are composed of new type of lighting. 】 Size is large, about 30 meters high, weight about 4 tons, so removed from volume, construction difficulty is high, the hazards control [ Using the engineering technology and management methods to eliminate and control hazards, prevent hazards leading to accident, causing injuries and property losses. 】 Strict and preventive measures. Based on the project for the demolished in high lamp demolition construction lines.
concentration of construction machinery, construction personnel demolished high lamp first, then high lamp installation. Make sure to achieve the goals of safety management, uphold the 'safety - - - , prevention first 'principle, be about to - - - Limit to reduce the operating procedures and work link, shorten the construction time as much as possible. The specific construction process is as follows:
2, hoisting risk reduction, countermeasures
( 1) Making scientific and reasonable hoisting plan, and approved before implementation.
( 2) Hoisting technical scheme and safety precautions before disclosure.
( 3) Hoisting should contact with the local meteorological department in advance before, when the wind is greater than the specified level, lifting operation is not allowed.
( 4) Must be used through testing equipment; Never use damaged or defective lifting equipment.
( 5) All mobile lifting equipment, must check regularly, time interval must not exceed six months.
( 6) Clean up the crane rotate within the scope of the scene, personnel shall not stand and work within this range.
( 7) Never use overload lifting pulley and hoisting rope.
3, high - - - Some countermeasures of risk reduction,
( 1) In aerial work, it shall strictly implement the relevant provisions of the company.
( 2) Homework personnel physical condition meets the requirements, no - such as fear of heights - - 。
( 3) Homework personnel dress conform to the requirements of the job.
( 4) Homework personnel to wear safety helmet, safety belt correctly, for more than 2 m job belt must hang up rear can work, ban hang with safety belt.
( 5) The alert zone beneath the operating point, and there are warning signs.
