Problems of tianmashan Shimao Shenkeng Hotel

The geological structure in most parts of Shanghai is unstable, especially in the Yangtze River Delta. Soft strata have caused many serious accidents. Because the hotel is designed to "hang" on the pit wall, it is a great challenge to the construction. The focus of geological investigation is whether the strength of pit wall is enough to support the whole hotel structure. Shockproof pit hotel is surrounded by steep rock walls. Shockproof is an extremely important issue. In order to solve this most important problem, the design team entered the geological survey results and engineering structure design of the hotel into the computer, and repeatedly checked the strength and seismic performance of the architectural design through a series of simulation tests, and finally ensured that the Shenkeng Hotel could withstand earthquakes of magnitude 9 or above. Fire fighting Because the hotel is built in a pit of 80 meters below zero, fire fighting and escape need to go from bottom to top. At present, there are no cases for reference in the space of human life. In case of fire, the fire truck can't enter the mine at all. In order to ensure the absolute safety of the guests, it is necessary to ensure that any balcony of the hotel is connected with the fire escape, which requires very high spatial layout design and is an incomparable difficulty in the above-ground space design. It is the most basic law of nature not to let stagnant water flow to the bottom. How to prevent water accumulation in 100m open pit has become a prominent problem, especially how to maintain the water level of artificial landscape lake at a safe level is a difficult problem. On the basis of studying the historical hydrological data of Shanghai, the design team installed a water pump to ensure that the daily water level change of the lake does not exceed the safety range of 500 mm In most projects, the construction unit has to solve how to transport personnel, materials and equipment upwards, and the construction of the deep pit hotel is to solve how to transport these downwards to the bottom of the mud pit 80 meters deep. Because the pit wall has a radian, the main structure of the hotel is also designed as an arc along the pit wall. Special-shaped steel is used, with irregular structure and at the edge of deep pit, so it is very difficult to transport and hoist. The bending design also increases the requirements for the overall strength of the structure.
