How long can the fan be hoisted and on what basis

You're talking about the basis of the wind turbine, right?

The foundation generally takes 7 days for civil health care. If the weather is good, it will take about 3 days.

The basis is that civil concrete has strength specifications.

For example, for large-scale fan installation, the foundation strength must reach more than 70%.

If the weather is good, you should wait at least 3 days, and if you have a large wind turbine, it is better to be more safe for 7 days.

A small fan for 3 days is enough.

1.The foundation generally takes 7 days for civil health care. If the weather is good, it can be about 3 days for a small one, and if you are a large fan, it is best to be more safe for 7 days.

2.The basis is that civil concrete has strength specifications, such as the installation of large fans, the foundation strength must reach more than 70%.

The foundation of general civil engineering and health care takes seven days. The weather is good for h8ua for about 3 days. The basis is that there are strength specifications for civil engineering mixed soil.

30 minutes, plant think to feed feed feed ask Weifang top wear.

Won't do anything to resurrect haha.

I don't know what basis I'm going up there and collecting it.

Actually, I don't know, for your own good, I can't decide.

If the concrete does not reach 75% of the design by 28 days, then there is really a problem with the concrete, and the general temperature can reach 80% of the design in 7 days

If it does not include construction positioning and pay-off, earthwork excavation, equipment entry and exit, and material reversal, up to 1200 t. of reinforcement70 formwork, 50 cubic meters of concrete, 7000 foundation rings.

First of all, we must know the foundation size of the fan, and then we must know the weight of the fan, the general foundation size is 50 100mm larger than the overall size of the fan foundation, the concrete strength and the number of steel bars are designed according to the weight of the fan, the foundation thickness is determined according to the design requirements and environmental requirements, and the number and thickness of the anchor bolts or the size and thickness of the connecting plate are confirmed according to the fan structure.

Here you are asking about the cost of one cubic meter, right? For the fan foundation, it is relatively simple, and the cost is four or five hundred yuan per square.

The exterior should be strengthened and covered with film to prevent temperature loss.

This is mixed with 107 glue to make the surface layer, in fact, the fan foundation is generally directly poured with concrete at one time, and then directly calendered, without plastering again.

After chiseling and brushing, water and moisten, and then sit on the bottom with the cement mortar of the concrete mark, and then pour the concrete to vibrate and compact.
