How did the bad weather factory in Russia open?

How to set up a factory in bad weather in Russia is as follows:

1. Earthwork shall be avoided in winter as far as possible. If construction must be carried out in winter, the construction method should be determined after technical and economic comparison. Make full preparations according to the determined construction method to ensure continuous construction.

2, winter construction, transportation roads and construction site anti-skid and fire prevention measures should be taken.

3. For earthwork excavated in winter, in order to prevent soil freezing, topsoil scarifying method, snow covering method, thermal insulation material covering method, greenhouse method and other methods can be used to prevent soil freezing and thermal insulation according to local conditions.

4. If the frozen soil needs to be excavated in winter, it can be thawed by fireworks baking, steam melting, electric heating and other methods according to the freezing depth and actual situation of the soil, and then excavated after the soil is thawed. If there is no freezing condition, manual, mechanical and blasting methods can be used for excavation.

5. It is not suitable for foundation replacement in winter construction (for example, sand and gravel cushion and lime-soil cushion are used to replace manual backfilling of miscellaneous soil and muddy clay, etc.). ). If soil replacement is needed, unfrozen sand, stone and soil should be selected and the construction should be carried out under the condition that the ambient temperature is not lower than -5℃.

6. For frost heaving soil, if the foundation has been frozen, all the frozen soil layer should be removed, or the frozen soil layer should be melted and compacted carefully. For non-frost heave soil, the frozen soil layer should be melted before the next process can be carried out.

7. When earthwork is backfilled in winter, the thickness of each layer of soil should be reduced by 20-25% compared with that in normal temperature construction. Compared with conventional construction, the reserved settlement should be increased.

8, winter construction dug up good soil to pile up, and cover it, to prevent freezing agglomeration, affect the backfill. All kinds of backfill should be arranged as far as possible before winter.
