It can bear more than 300 kilograms per square meter. Inner diameter 155*95*60, area 1.47 square, volume 0.88 cubic weight. After being filled with water, it is 880 kg, and the corresponding bearing capacity is about 600 kg.

What needs to be clear is:

1. What was the original function of this building?

2. Whether there is a planning procedure and formal design.

3. Year of construction and approximate quality.

I will feel more at ease when I know it clearly.

Extended data:

Floor maintenance

1, the concrete strength with a span of more than 8m ≥ 100%, and the formwork can be removed only when the concrete strength is more than 8m and less than 75%; When the concrete strength is ≥ 1.2MPa, the construction floor can be occupied. (Generally, the strength can reach ≥ 1.2MPa 24 hours after watering, and it takes 7~9 days under normal maintenance in spring, summer and autumn; Under normal maintenance in winter 10~ 15 days).

2, under normal maintenance conditions, shall not be less than 2 times a day; Make sure that there is 1 1~ 16 minutes of water on the ground every time.

3. Moisturizing curing of concrete is very important for its strength growth and improvement of various properties, especially early proper curing can avoid surface dehydration and greatly reduce the occurrence of early expansion cracks of concrete.
