After the steel binding of the bearing platform is completed, the concrete of the bearing platform is poured. In the case of mass concrete, the following measures will be taken to avoid concrete cracking caused by hydration heat of concrete:

1) Optimize the concrete mixture ratio;

2) Concrete is poured in layers to accelerate the heat dissipation of concrete and reduce the temperature difference between the inside and outside of concrete;

3) Reduce the mold-entering temperature of concrete and choose low-temperature construction;

4) Concrete materials should be covered to avoid sun exposure, and cooling water should be added to the concrete to reduce the warehousing temperature;

5) According to the requirements of design drawings, the cooling water pipes are buried in concrete for cooling, and the peak temperature rise of hydration heat of concrete is reduced through water circulation. After the concrete is poured to the height of the water pipes, the cooling water pipes of each layer begin to flow to ensure a certain water flow to ensure the cooling effect.

6) After concrete pouring, attention should be paid to covering heat preservation and strengthening moisture retention. In case of sudden drop in temperature, attention should be paid to heat preservation to prevent cracks.
