Shuishang Renjia Community, Zhuozhou City, Baoding, Hebei Province. On the 31st, heavy rain flooded the entire community. Then the underground garage was directly crushed and collapsed. It is said that the water level reached as high as 5 meters at its peak.

The issue that everyone is debating is that the water level was very high, and the underground garage should have already been filled with water, with the internal and external water pressure balanced, so in theory it should not have collapsed. But the on-site footage shows that after the underground garage collapsed, even when the outside water level dropped, water still kept flowing continuously into the underground garage. Obviously, before the underground garage collapsed, the inside of the garage should not have been full of water.

If the internal and external water pressure was not balanced and the roof water level reached as high as 5 meters, then the five parties responsible for the project can sleep soundly, since the water pressure exceeded the design load by so much.
