1. First of all, there must be enough construction personnel to carry out 24-hour uninterrupted construction.
2, machinery and operating personnel must be in place, do people stop machinery, operating personnel succession system.
3. The materials must be contacted with the manufacturer in advance, and can be used if needed.
These are the most basic points. Of course, the venue must also be ready:
1, before entering the winter construction, earthwork construction must be completed, because earthwork cannot be constructed in winter, otherwise the quality cannot be guaranteed.
2. Cast-in-place concrete and precast works. First, set up your own mixing station, and it is best to design the mixing station as down heating and water heating. Through a process, the material can be heated while entering the blender and stirred by the water heated by the boiler. Insulated tank car transportation.
3. It is necessary to build and design a thermal insulation shed on the project site, which can be suitable for vehicles and people to pass, arrive and keep warm and ventilated, and ensure that the temperature in the thermal insulation shed can reach 10 or above. Temperature can be obtained by fire and electricity, of course, the cost is higher. Be sure to pay attention to safety here.
4, pay attention to the health after concrete pouring, because the shed fire easily leads to concrete cracking.
5, take the way of process first. In other words, the formwork and reinforcement works were completed ahead of schedule.
6, can check in advance, acceptance in advance.
7, good relationship with the supervision, can be on call, check at any time.
8. There is also mobilization.
The above is my little experience. I worked at MINUS 20 degrees. That's really bitter and tiring.
