8. Take effective measures for cement and other materials that are not suitable for freezing in rain and snow, and set up protective sheds to ensure the engineering quality and reduce economic losses. 9, it is forbidden to vehicles with mud on the road, if this happens, should be cleaned up immediately. 10. After the rain and snow, clear the snow above the foundation trench and the square trench in time to prevent the foundation trench from collapsing due to excessive snow. 1 1. If there is ice and snow on the road surface after snow, immediately organize construction personnel to clean up the accident road and clean up the important intersection sections. Ensure smooth construction roads, ensure social traffic safety and avoid social traffic accidents that affect engineering construction. 12, during the snow removal, the construction personnel must do a good job of safety protection to avoid personal injury. 13, after concrete structure is poured, take heat preservation measures for maintenance, pay attention to fire prevention when using coal stove for heating to prevent gas poisoning, and assign special personnel to be responsible for coal burning in each work area. 14. Before entering the curing shed, it is necessary to check whether there are toxic gases such as gas, and open flames are strictly prohibited. 15, protective measures should be taken for aerial work, and operators must fasten their seat belts. Three. Strengthen the safety management of winter construction. During winter construction, safety accidents occur frequently. The project department must follow the policy of "safety first, prevention first, comprehensive management" and the principle of "production must be managed safely", earnestly implement the responsibility system for production safety at all levels, and implement various safety production measures according to the characteristics of winter construction to ensure the safety of winter construction and create conditions for everyone to have a harmonious and safe Spring Festival. The project department is required to focus on the following aspects. 1, strengthen the management of falling prevention. The construction site should improve the setting of safety protection facilities such as building edge, roof edge and reserved holes, elevator wellhead and stair edge. Protective facilities such as protective shed and protective railing erected on the construction site must be intact, firm and effective, and meet the standard requirements. At the same time, eye-catching safety warning signs should be set around the protective facilities to prevent falling from high altitude; If the distance between the scaffold and the building is too large and exceeds the requirements of the specification, safety protection measures should be taken; Climbing workers must wear anti-skid and anti-freezing measures such as anti-skid shoes and protective gloves, and wear safety helmets and fasten safety belts correctly as required; In case of bad weather such as rain and snow, the accumulated water and snow on the construction site should be removed in time, and it is strictly forbidden to forcibly organize construction work in rainy, snowy and windy weather; For the removal of scaffolding and safety protection facilities on the construction site, a strict internal examination and approval system should be implemented, and it is not allowed to be removed at will. 2, strengthen the management of hoisting machinery, focusing on equipment testing, repair and maintenance, to ensure that all kinds of safety devices and limit devices are effective and reliable; It is necessary to inspect and monitor the foundations of tower cranes, material hoists, external elevators and other equipment to improve the anti-freezing, anti-wind and anti-collapse capabilities of equipment; The hoisting machinery used in the construction site must be hung with safety operation rules and safety warning signs, and the acceptance inspection system shall be strictly implemented. 3. To strengthen the safety management of deep foundation pit construction, it is necessary to strengthen the monitoring and management of foundation pit wall support, set observation points, observe the changes of slope and adjacent buildings and structures at any time, find hidden dangers in time, and take effective measures to prevent collapse accidents; The periphery of the foundation pit must be effectively protected, and obvious warning signs should be set; Weight limiting plates for stacking materials should be set around the foundation pit, and it is forbidden to pile up a large amount of materials.
4, do a good job of poisoning prevention, flammable, explosive and toxic substances on the construction site to establish a strict management system, fixed-point classified storage, clearly marked, and someone who's in charge. Dormitory should have enough safe distance from the warehouse where inflammable, explosive and toxic substances are stored. Operators who use toxic substances should be equipped with safe and reliable protective equipment, and take effective measures to keep the workplace well ventilated to prevent poisoning accidents. Dormitory doors and windows should be intact, heating facilities should be used correctly, and indoor ventilation should be maintained. It is strictly forbidden to use firewood and charcoal fire for heating in the dormitory, and it is strictly forbidden to pull and connect electricity facilities indiscriminately to prevent smoke poisoning and fire accidents. At the same time, the management of edible salt should be strengthened to prevent sodium nitrite (industrial salt) poisoning accidents.
5. Strengthen the fire safety management on the construction site. In winter, the climate is dry and the wind is strong, which is prone to fire accidents. It is necessary to focus on the fire safety management of key parts such as work areas, living areas, inflammable and explosive goods storage areas, warehouses and power distribution facilities, and implement key prevention and monitoring to eliminate fire hazards. It is necessary to allocate fire-fighting equipment reasonably and effectively; Strictly implement the hot work approval system, set up a hot work guardian, and implement on-site monitoring to ensure that there are enough safe passages and fire prevention spaces on the construction site. The safe passage should be kept clear and clearly marked. Implement special inspection and acceptance management to prevent fire accidents. 6. Strengthen structural safety construction control. For concrete structures (especially long-span structures and cantilever structures) constructed in winter, the time of formwork removal in winter must be controlled in strict accordance with the requirements of the code, and the formwork removal test blocks should be made well. In winter, the growth rate of concrete strength is slow, so it is forbidden to dismantle the formwork in advance to avoid quality and safety accidents caused by insufficient concrete strength.
