Abstract

An underground space frame structure includes vertical support piles and multi-layer horizontal components. Each of the vertical support piles includes a pile body vertically disposed in a pile hole before excavating a foundation pit. The pile body includes an upper pile body and a lower pile body. The upper pile body is a rectangular body, and the lower pile body is a cylindrical body. An expansion section is located between the upper pile body and the lower pile body. A cross-sectional area of the expansion section is greater than a cross-sectional area of the upper pile body and a cross-sectional area of the lower pile body. The upper pile body, the expansion section, and the lower pile body are coaxially arranged from top to bottom in the pile hole. The multi-layer horizontal components are constructed from top to bottom.
