Abstract

The invention relates to a subway shield segment, including: a sheet body, a ridge, an upper boss, a lower boss, a through hole, a bolt groove, a first waterproof layer, a second waterproof layer, and a butt joint plate, and the sheet body is an arc The inner surface of the sheet body is provided with a ridge on the central axis, the inner surface of the sheet body is respectively provided with bolt grooves at the four corners, and the front and rear end faces of the sheet body are provided with butt plates. The two ends of the hole are respectively connected to the bolt groove and the butt plate, the upper end surface of the sheet body is provided with an upper boss, the lower end surface of the sheet body is provided with a lower boss, the outer surface of the upper boss and the inner surface of the lower boss are both A first waterproof layer is provided, and a second waterproof layer is provided on the front and rear end surfaces of the sheet body on the periphery of the butt plate. The invention has the advantages of good structural stability, strong supporting force, good waterproof and leak-proof effect, and strong durability, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of subway construction, in particular to a subway shield segment. Background technique [0002] Subway construction generally adopts shield construction. The shield segment is the main assembly component of the shield construction and the innermost barrier of the tunnel. It bears the role of resisting soil pressure, groundwater pressure and some special loads. The shield segment is For the permanent lining structure of the shield tunnel, the quality of the shield segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel. Existing shield segments generally adopt arc-shaped sheet structures, and are sealed and waterproof by sealing strips. The structural support strength is relatively weak, and the installation is relatively complicated. Contents of the invention [0003] The object of the present invention is to provide ...
