Segment structure with horizontal pin type mortise and tenon and push-and-press fastening type joint connecting assemblies

Abstract

The invention belongs to the technical field of shield tunnel lining structure correlation, and discloses a segment structure with horizontal pin type mortise and tenon and push-and-press fastening type joint connecting assemblies. The segment structure comprises shield segments and the horizontal pin type mortise and tenon connection assembly which are connected, and each assembly comprises a mortise and tenon joint connecting piece and a push-and-press joint connecting piece. Each shield segment is in an arc shape. The mortise and tenon joint connecting pieces are connected with two oppositerectangular ends and the push-and-press joint connecting pieces are connected with two opposite arc-shaped ends so as to realize axial and circumferential connection of the adjacent shield segments.Each mortise and tenon joint connecting piece comprises a male clamping joint and a female clamping joint, wherein a T-shaped second containing cavity is formed in each female clamping joint; and eachmale clamping joint comprises a first C-shaped piece and a connecting body connected to the first C-shaped piece, and each connecting body is accommodated in the corresponding second containing cavity. During mounting, the connecting bodies are clamped into the second containing cavities through sliding, so that the male clamping joints and the female clamping joints form mortise and tenon connection. The segment structure is easy to construct, and cost and manpower and material resources are reduced.

Description

technical field [0001] The invention belongs to the related technical field of shield tunnel lining structure, and more specifically relates to a segment structure with a horizontal pin type mortise and tenon connection assembly and a push fastening type joint connection assembly. Background technique [0002] In recent years, with the increasingly serious problem of urban traffic congestion, more and more cities have begun to construct subway projects. Due to its small impact on the environment, the shield machine is suitable for large buried depth, high earth pressure, and high water pressure construction, and has the advantages of low cost and wide application range. It occupies a dominant position in the construction of urban subway projects and has been It has become an indispensable general construction technology for tunnels. [0003] In the past 30 years, shield technology has developed rapidly, and shield forms have been diversified. The shield tunnel segment is th...

AI Technical Summary

Problems solved by technology

Most of the traditional shield segments are connected by longitudinal and circumferential arc bolts. The arc bolts are easy to deform. It is often difficult to perforate the arc bolts during construction. At the same time, special personnel are required to lock the bolts, which consumes a lot of time and manpower.
