This invention provides a basin excavation inverse method. Its major construction step is the open excavation in retaining structure edge at the first step , and digs a kind of pot-style structure, and pour the top layer concrete of underground structure, and provides dug holes; then excavates in another way, it is a pot of architecture, and pours the top structure concrete of the underground two-story, and allows dug holes; following mining, and pouring the top three underground structure plate and the top four floors underground structure ; the bottom of base plate structure is divided into two parts ;it excavates scope of the bottom floor firstly, the pit digs to the bottom, pouring concrete, then the envelope around 6 ~ 10 meters pumps the excavation. This construction method is suitable for the large pit area, depth deeper large-scale construction projects, as it constructs conveniently, saves manpower and resources to improve the progress of the project, and shortens the construction periods.
