Description

Underground station with inverted station hall layer

Technical Field

The utility model relates to the technical field of underground stations, in particular to an underground station with inverted station hall layers, which is suitable for projects such as urban rail transit, urban railway, magnetic levitation and the like.

Background

Urban rail transit station types are divided into underground stations, ground stations and elevated stations, and the station types are closely related to factors such as laying modes of rail lines, line burial depths and the like. The underground station consists of a station hall layer and a station layer, and the layout form between the station hall layer and the station layer in the existing engineering design is that the station hall layer is arranged on the station layer or the station hall layer and the station layer are arranged on the same layer. With the increase of the traffic operation of rail transit lines in various big cities in China, the difficulty of planning line construction in line network construction is increased more and more, more and more examples of stopping line crossing in municipal works such as existing rail lines or municipal tunnels, comprehensive pipe galleries and the like appear, and designers usually adopt two design schemes under similar conditions in the past. One is that the existing engineering is passed through in a mode of underpass, then the burial depth of the station reaches the structural depth of three layers and four layers (about 25-40 meters) underground, a plurality of deep foundation pit stations emerge, and the engineering risk and the economic cost are extremely high. The second mode is that the crossing is crossed in an upper span mode, then the track surface line of the station is shallow, the station is correspondingly designed to be in the form of a ground hall station with a station hall layer arranged on the ground or an underground one-layer side station with a station platform and a station hall arranged on the same layer, and the like. However, the track traffic lines and stations are mostly arranged below urban roads, existing buildings around the roads are dense, urban land use is tense and difficult to coordinate, and the investor can only select an underground multi-layer station scheme which saves land and increases burial depth. At the present stage, for the project of stopping the line from passing through in the existing municipal engineering, the existing project is mostly passed through by adopting a downward-penetrating mode, if a station needs to be arranged, the burial depth of the station can reach the structural depth of three or four layers (about 25-40 meters) underground, a plurality of deep foundation pit stations are developed, and the project risk and the economic cost are extremely high.
