Winter construction measures

I. Overview of the Project:

The Lakeside Garden Phase II 1# residential building project in Gaotang County is located in the south of Gaotang County Committee, with a construction area of 5,609 square meters. At present, the main body has been completed and entered the stage of large-scale decoration construction. According to past experience, winter construction is carried out when the daily average temperature is lower than 5℃ for five consecutive days, so the decoration stage coincides with winter. In order to ensure the smooth and safe construction of the project and complete the production tasks with good quality and quantity, the following winter construction measures are specially formulated.

Second, the organizational measures:

Organizational measures

1, set up the winter construction leading group of the project department headed by the project manager, responsible for the winter construction of the project department.

Team leader: Li Minghua

Members: Sun, Ren Laigang, Wang, Wang Jun.

2. Formulated a feasible construction scheme.

3, to carry out on-site production personnel winter construction safety, quality prevention knowledge education.

4, organize the establishment of emergency rescue preparation team.

Team leader: Ren Laigang. Team members:,, Wang, Wang Jun

5, send information officer, contact the company regularly, timely grasp the weather forecast and early warning of cold wave and strong wind, so as to take timely protective measures.

(2) Technical measures:

A, site construction measures:

1, the construction site is equipped with all kinds of necessary anti-freezing and waterproof appliances and materials.

2. Before entering the winter construction, the personnel who add additives, temperature measurement and insulation personnel, boiler stoker personnel and boiler management personnel shall be treated.

3, keep in touch with the local meteorological observatory, timely receive the weather forecast, cold snap attack.

4. During the construction period, assign special personnel to measure the indoor and outdoor temperatures, and make records in time.

5, the temporary water supply pipeline and plastering materials such as heat preservation and antifreeze measures.

6, glass engineering in winter construction, the operating temperature should not be lower than 5℃, such as construction must be glass, inlaid with synthetic rubber and other materials to indoor heating equipment.

7. During construction, arrange the installation of plastic-steel windows first, so as to facilitate indoor engineering. During construction, close the doors and windows, plug the side seams of the doors and windows and the hole, and do a good job in sealing and heat preservation of the construction hole, material transportation and stairwell. Reasonable arrangement of ventilation time.

8. When brushing ready mixed paint in winter, you should add 2.5% drier and 5% rosin water by weight of ready mixed paint. During construction, smoke and moisture should be removed to prevent the loss of light and viscosity.

9. Laying and maintaining the temporary roads on site, especially the construction roads in front of the building, to prevent water from freezing and materials from entering the site.

10, transform temporary facilities, such as mixer shed, etc. , completes the heat preservation and rainproof measures, prevent frost and rain from leaking into the shed, and drain the water in the pump after the mixer is used to prevent frost cracking.

1 1. Effective measures should be taken for cement and other materials that are not suitable for freezing in rain and snow, and protective sheds should be set up to ensure the engineering quality and reduce economic losses.

12, collect meteorological information in time, make construction arrangements in advance, such as outdoor decoration, waterproof engineering, roofing engineering and other sub-projects to avoid rain and snow.

B, roof construction measures:

1, roofing construction is strictly prohibited in rainy and snowy days and weather conditions above category 5 wind.

2. The expanded vermiculite thermal insulation materials piled up during construction and on site shall be covered in rainy and snowy days.

3, roof cement mortar leveling layer is strictly prohibited in the rain and snow weather construction.

4. The roofs of1# buildings are all made of TS-C coiled materials, and the construction method is full adhesion. Before construction, we should control the moisture content at the grass-roots level. In case of rain and snow, the construction can only be started after the base is dry.

5. In rainy and snowy days, it is advisable to avoid building a tri-tile roof with overhangs around it. In case of rain and snow during construction, rain and snow protection measures should be taken and covered in time.

C, decoration technical measures:

1, exterior wall decoration should avoid rainy day construction, wet before plastering, and avoid rain. If it is polluted, it should be scrubbed in time to protect the finished product.

2. Before the exterior wall coating is wet, rainproof measures should be taken to avoid getting wet.

3, interior wall paint, charcoal insulation engineering construction, should pay attention to smoke, fire prevention measures, to prevent pollution and fire.

D, outdoor engineering

1. The excavated earthwork must be prevented from freezing at the bottom of the foundation trench or the foundation and other facilities of adjacent buildings. If the next procedure is not carried out in time after the foundation trench is dug, a soil layer with appropriate thickness should be reserved on the basement elevation and covered with thermal insulation materials.

2. When excavating in winter, cover the unfrozen land together to prevent freezing when backfilling.

3. Before backfilling, the ice, snow and thermal insulation materials in the basement should be cleaned. When tamping manually, the thickness of each layer of soil shall not exceed 20cm, and the tamping thickness shall be 10- 15cm. And should be continuously compacted layer by layer.

4. In order to shorten the curing time of outdoor ramp and aproll concrete, the cement dosage per cubic meter of concrete shall not be less than 300Kg, and the water cement ratio shall not be greater than 0.6, and an early strength agent shall be added.

5. In order to reduce the frost damage, we should try to reduce the water consumption in the mixture ratio, control the slump, and give priority to the use of superplasticizer.

Third, the safety measures:

1, set up the construction safety duty team in winter and rainy season. The personnel on duty take turns to be on duty every day and write a written record. Find hidden dangers, formulate rectification measures and supervise their implementation.

2, rainy days and more than six winds, stop outdoor work. .

3, tower crane foundation must always observe the settlement, such as uneven settlement, should be timely reinforcement foundation.

4. Strengthen the management of on-site fire sources, and prevent explosion when using natural gas and gas. When using coke oven, coal stove or natural gas and gas, pay attention to ventilation to prevent gas poisoning.

5, such as the use of calcium chloride, bleaching powder during construction, to prevent skin corrosion.

6. Sodium nitrite is highly toxic and should be kept strictly to prevent accidental poisoning.

7, carefully check the electrical equipment used in the field, all outdoor use must have waterproof and moisture-proof facilities, construction wires must be in good condition, and buried, switch box must be reliably grounded; Conduct a comprehensive inspection of the leakage protector to ensure effective use and eliminate potential safety hazards.

8, pay attention to life hygiene, dormitory should have rat prevention measures and regular measures, to ensure that the general indoor air exhaust unobstructed, it is forbidden to pull wires, toilet hygiene designated persons responsible for regular flushing.
