Excavation and quarrying hollowed out a mountain, leaving a pit nearly 90 meters deep, and now it has created a world miracle
The development of urban modernization is inseparable from the construction of many urban exterior projects. These buildings, which symbolize the economic and commercial development of the city, have brought us different visual impacts. The urban architecture that I want to introduce to you today is a bit special, because It was built in a "cavity". The "cavity" here is not a "hole" in the traditional sense, but a hole left by blasting the mountain and quarrying it, with a depth of nearly 90 meters. It is a city built on such a terrain. Isn't the architecture particularly peculiar? Let's take a look together.
This building is the famous Shenkeng Hotel in Shanghai. Before the end of the 1950s, the Shenkeng Hotel was still a stone mountain covering an area of 0.23 square kilometers. Since 1950, the mountain has been blasted and quarried. It was hollowed out, and even continued to be dug underground, leaving nearly 90 meters deep and covering an area of 36,800 square meters. This pit is the famous Tianma Mountain pit. Because it is relatively desolate and the area of the quarry pit is large, It was abandoned for a long time until 2006.
In order to make good use of this pit, a company in Shanghai decided to use this terrain to build a unique hotel. It sounds simple, but the Tianmashan pit is a place where people used to quarry stones. The cliffs are fragile and the Tianma is just 90 meters away The mountain pit is very difficult. This project is called a worldwide construction problem. There is no case in history to refer to and learn from. During the construction process, it can only be done step by step.
After 12 years of planning and construction, the hotel finally opened in November 2018, with a total cost of 600 million yuan, a deep pit hotel with an altitude of minus 65 meters, 17 floors underground, and even one floor underwater. We don’t know the entire hotel experience What kind of difficulties, but it created the world's lowest artificial foundation pit miracle.
