The Japanese left a huge pit in China. What difficulties did China encounter in filling it out?

I think the first thing to do in filling this huge pit is how to fill it. It's also true that people at that time were smart and wanted to make this pit into a hotel, and then the design drawings, because this was never done before. It can be said that many problems that are not problems have become problems here when building this huge pit hotel.

In 2006, Shimao Group got a piece of land, including a deep pit. In the past, such a waste pit would be transformed into a garbage recycling plant, but this waste pit is a bit special-it is located in Sheshan National Tourism Resort, and it is definitely impossible to build a garbage dump. So, what about filling it out and then developing it? It seems a pity that there are many good green plants on the cliff, and the natural scenery hanging on the shore is also charming.

Then these geniuses thought of building this place into a unique hotel. But despite the ideas, there will still be many problems.

To put it simply, there is no precedent for such a "falling building"-no building is built in a pit. Many solutions to problems have to be created by ourselves. After all, in architecture, one place is different and everywhere is different.

The first question to find all the difficulties is:

How to get to the bottom of the pit? It is reasonable to say that this is not a problem at all, but after careful understanding, this is a "Z-shaped" plank road with more than 220 steps. One-way trip takes about 15 minutes. For safety reasons, only 12 workers can walk at a time. At the peak, about 300 people will go down the well, and workers will frequently carry tools and materials up and down. As a result, although some people came at 8 am, they didn't go down to the bottom of the pit until noon!

Of course, there are many others, such as Shenkeng Hotel. Can it resist earthquakes? Faced with such a situation, how to carry out blasting? How can more than 70 thousand concrete be transported to the bottom of the pit? There were countless problems, but they were all solved in the end.
