Abstract

The invention discloses a shield method lining structure used for a rail transit station. The shield method lining structure includes a standard lining section and a special lining section arranged along the axial direction of a shield tunnel; the standard lining section is composed of a number of concrete lining rings; the special lining section is composed of a number of special lining rings; the special lining ring is composed of concrete lining blocks and steel lining blocks; and the steel lining block is provided with an opening, which can be provided with a entrance-exit or an air duct.The advantages of the shield method lining structure used for the rail transit station are as follows: the inside of the circular lining structure can not only be provided with a station platform layer and a station hall layer structure, but also be provided with structures connected with the outside such as the entrance and exit, and the air duct, which not only meets the internal use function requirements of the rail transit station, but also meets the external connection requirements.

Description

technical field [0001] The invention belongs to the technical field of shield tunnels, and in particular relates to a shield lining structure for rail transit stations. Background technique [0002] Usually, the construction methods of subway underground stations include: open-cut method, cover-excavation method, shallow burial and underground excavation method. in: [0003] (1) Open cut method [0004] The open-cut method is more commonly used for the construction method of subway stations, because the open-cut method has certain advantages, and the quality is guaranteed compared with other construction methods, and the construction period is relatively short and the construction speed is fast. Common methods of construction. [0005] However, this construction method still has certain deficiencies, and there are conditional restrictions, because the site area required for construction is relatively large, and the surrounding traffic and life will be affected to a certai...
