Anonymous users2024-02-11For construction, there are many places to pay attention to in winter construction. Today, I will introduce to you two points that need to be paid attention to in winter construction.
01Construction. 1) The indoor edge and opening must be set in place according to the requirements of the specification. Indoor stairs, window openings and edge masonry height is less than 2250px, with steel pipes, fasteners combined height of the protective railing, the bottom of 500px for kick protection, in order to maintain the stability of the protective frame, in the middle of the frame body to add a protective rod.
2) The construction and transportation sites shall not freeze due to the phenomenon of water accumulation due to the temperature being too low, resulting in potential safety hazards.
3) In the event of heavy rain, fog, strong wind above level 6, and ice on the rail frame and cable, the operation must be stopped, and the ladder cage must be lowered to the bottom floor to cut off the power supply. In the cold season of construction machinery, when the outdoor temperature is lower than 5, all the mechanical equipment cooled with water should be discharged in time after the use of the mechanical equipment cooled with water. Before adding antifreeze, the cooling system should be cleaned for mechanical equipment using antifreeze, and the antifreeze coolant should be prepared in proportion to the temperature requirements.
4) Pay attention to remove the flying thorns from the iron wedge head to avoid hurting people. The person with the iron wedge and the person with the hammer must not face each other, and must be at an angle of 90 ° so that the hammer does not turn around and hurt people. When making iron wedges, use thick iron wire or steel bars to make handles to prevent hand damage and accidental injury.
In the winter pit construction, the slope protection measures should be formulated according to the soil conditions and engineering characteristics in the plan, and the slope stability should be checked during construction and after thawing, and measures should be taken in time for cracks, loose soil or deformation of slope protection piles.
5) All kinds of materials in the site are stacked to the designated place according to the material classification, and the stacking height shall not be higher than and there are anti-dumping protection measures and fire prevention and anti-theft measures.
6) Strengthen labor protection in seasonal construction. After frost and snow, the working surface should be cleaned in time, and the temporary operating frame and edge protection facilities used must be inspected by safety management personnel before they can be used to prevent the occurrence of falling accidents from heights.
02 Firefighting. 1) Organize relevant personnel to study the documents, specifications and winter plans for fire protection, and make preparations for winter fire protection. Before the winter application, the project department organized the safety and fire protection publicity and education work for the employees, formulated the safety and fire protection measures of the winter application, and conscientiously implemented the rules and regulations.
2) The fire-fighting equipment shall be inspected daily, and shall be replaced in time if it does not meet the fire protection requirements.
3) Pay attention to check the insulation of fire hydrants and temporary fire pipes, and solve them in time to avoid future troubles.
4) The flammable materials on the site should be cleaned and protected in time and kept away from the fire source.
5) The open flame operation strictly implements the fire application system. Someone must watch the fire for electric welding, and the fire watchers must carry fire-fighting supplies and are not allowed to leave their posts without authorization. The fireproof cotton curtain should be in accordance with the instruction manual during use, and it should be replaced in time if it does not meet the requirements of use.
6) When welding connection is adopted, careful fire insulation and fire prevention measures must be taken before welding.
Hello! It's a break from work for a while.
In addition to the reason why the temperature is low and inconvenient for workers to construct, it is also to ensure the quality of the house. Coordinates Northeast cities, generally speaking, the winter break period is mostly from November to March of the following year, of course, it also depends on the specific situation of different construction units and different construction projects. >>>More
1. Article 1 of the Technical Regulations for Concrete for Building Structures (JGJ3-2002) stipulates that the difference between the internal temperature and the surface temperature of large-volume concrete, and the difference between the outer surface of concrete and the ambient temperature should not exceed 25 degrees Celsius; >>>More
First of all, it is important to pay attention to the tightness between the layers. >>>More
1. Bathroom waterproof construction steps.
Step 1: You can use slightly coarser cement as a primer first, and wait for the cement to dry before brushing the waterproof coating. But in painting money, the ground should be flat and there should be no grooves. Water is then sprinkled on the ground to expel the gas from the small holes. >>>More
First of all, you must ensure your own business level, like the construction industry pays more attention to practical experience, some masters have worked for a lifetime, especially carpenters are more stubborn, you must improve your ability, so that others can convince you that you can manage your people more conveniently, secondly, use different methods for different people, and quietly listen to what others say when they encounter problems that they don't understand, (learn more by themselves) don't talk nonsense for the sake of face, so you will be laughed at by others. I haven't been doing it for long, and anyway, I always remember to learn more.
