What measures should construction sites take to cope with rainy and hot weather?

1. All construction companies should make full use of "migrant workers' schools" to educate employees on heatstroke first aid knowledge, enhance employees' self-protection capabilities and awareness of prevention; reasonably adjust their work and rest time, and adopt the method of "working at both ends and resting in the middle" Methods: Try to avoid open-air outdoor operations during high-temperature periods. Personnel who are elderly, in poor physical condition, or not suitable for high-temperature operations must be transferred to other positions in a timely manner. Sufficient heatstroke prevention and cooling supplies and tea must be provided at the construction site, and cooling oil, Rendan, and Fengyoujing must be distributed. and other medicines to prevent heatstroke; effective ventilation, heat insulation, and cooling measures must be taken in high-temperature workplaces; health management of construction site canteens must be strengthened to ensure food hygiene and avoid poisoning incidents; dormitories must be strong and safe, well-ventilated, and equipped with fans, etc. Cooling equipment, strengthen temporary power management in dormitories, and prevent fire accidents caused by route overload.

2. After each enterprise receives meteorological warning information about disastrous weather, it should immediately communicate it to all project departments, and activate emergency plans at the enterprise and project department levels to ensure that emergency rescue supplies are in place. Enterprises and project departments must arrange personnel to be on duty 24 hours a day, with more than 2 personnel on duty. All personnel on duty and emergency rescue personnel should have their mobile phones turned on 24 hours a day until the disastrous weather warning is lifted. Each enterprise should report the list of on-duty personnel and contact numbers to the Municipal Safety Supervision Station in advance.

3. The main person in charge of each enterprise personally leads the team, organizes personnel to comprehensively investigate potential safety hazards at the construction site, and implements rectification measures in accordance with the principle of "three determinations" (determination of personnel, timing, and measures) to ensure that Completely eliminate hidden dangers and implement preventive measures before the onset of disastrous weather.

4. During typhoons and rainstorms, the use of all construction hoisting machinery and equipment should be immediately suspended at the construction site, and the equipment foundation and fastening connections of wall-attached devices, derrick cables, etc. should be comprehensively inspected to maintain the equipment foundation. The site has smooth drainage. The material hoist basket, construction elevator car, outdoor basket, etc. must be lowered to the ground, the tower crane hook should be retracted to the uppermost end, and the boom should be able to rotate freely 360 degrees.

5. It is necessary to comprehensively clean up the construction materials and construction waste on the scaffolding as well as various billboards and promotional slogans erected outside the scaffolding. If necessary, temporarily remove the scaffolding safety net to reduce wind load. , ensuring overall stability. At the same time, it is necessary to comprehensively inspect the fastener bolts, foundation drainage and wall connecting measures at the main nodes of the scaffold to ensure compliance with the requirements of the "Safety Technical Specifications for Fastener Steel Pipe Scaffolding in Construction". Scaffolding outside buildings in high-rise buildings and open areas must be appropriately dense with connecting wall parts.

6. Comprehensively inspect the temporary facilities at the construction site, especially the construction site offices, staff dormitories, canteens and other living facilities. Appropriate reinforcement measures should be taken based on the structural conditions of the facility, and the reinforcement effect should be inspected and accepted in conjunction with the construction unit, supervision unit, and production and installation unit of temporary construction facilities. For temporary construction facilities that cannot be guaranteed to be safe after being reinforced, or if the temporary construction facilities are close to scaffolding, newly built gables, temporary walls, foundation pits, etc., the accommodation personnel in the temporary construction facilities must be resolutely evacuated and proper measures must be taken. placement.

7. Comprehensively inspect the temporary electricity consumption at the construction site and the daily electricity consumption of employees to ensure the effectiveness of various leakage and short-circuit protection devices and the insulation of the lines. During typhoons and rainstorms, outdoor electrical equipment and electrical boxes must be protected from rain, and all outdoor power lines must be cut off. At the same time, lightning protection and grounding must be done for high-rise metal parts on site and steel structure operating sheds erected in open areas.

8. The connection nodes between steel structure engineering components must be fastened in place. Before the structural components form a stable spatial structure system, temporary anti-overturning measures should be taken. During heavy storms, outdoor climbing operations should be suspended immediately to avoid accidents.

9. The foundation pit project should strengthen drainage and be equipped with backup power supply to ensure smooth drainage. It is necessary to implement dedicated personnel to promptly remove the load around the foundation pit to prevent collapse due to excessive pile load. It is necessary to strengthen the management of foundation pit monitoring units, increase the frequency of monitoring and patrolling the side wall support of foundation pits and surrounding buildings, structures and roads, and report any abnormal situations in a timely manner. It is necessary to contact the construction management department and neighborhood committee where the project is located in a timely manner to find out how the foundation pit affects the surrounding buildings (structures), above-ground (underground) facilities, and residents' lives. If safety cannot be guaranteed, personnel should be evacuated in a timely manner. and foundation pit reinforcement measures.

10. It is necessary to promptly reinforce structurally unstable operating sheds, moso bamboo protective frames, and newly constructed walls that have not yet been connected to structural columns and ring beams, and set up warning areas to prevent personnel from entering. If there are scattered materials on the floor, measures should be taken to cover them or move them to the ground in time to prevent them from being blown down by strong winds and injuring people.

11. It is necessary to strengthen the inspection of fence facilities and promptly reinforce or dismantle problematic fences to avoid affecting pedestrians on the roadside or related public facilities.

12. After the disastrous weather, all enterprises must conduct a comprehensive inspection of the construction site, organize debugging, maintenance, and overhaul of relevant equipment and facilities in a timely manner to ensure that potential safety hazards are eliminated before construction can be resumed.
