Problems solved by technology

When the shield tunnel boring machine (TBM) is used for construction, this high ground stress will easily lead to serious deformation of the assembled segment lining due to insufficient support stiffness, resulting in segment misalignment and water leakage, forcing Segment lining structure abandoned during design

Abstract

The invention discloses a segmental lining reinforcing type combined supporting structure which comprises segments and arch-shaped racks, wherein the segments are made of reinforcing steel bars and concrete; the radial cross sections of the arch-shaped racks are C-shaped; mounting grooves are respectively formed in two sides of the segments; one arch-shaped rack is mounted inside mounting grooves of every two adjacent segments and is fixedly connected with the two adjacent segments; the outer sides of the arch-shaped racks are opened. According to the segmental lining reinforcing type combined supporting structure disclosed by the invention, every two adjacent segments are fixedly connected through the arc-shaped rack, so that the overall rigidity of a joint part can be improved, meanwhile slab staggering of the joint part is reduced, and the number of hand holes of the segments is reduced; due to the mounting grooves in two sides of the segments, a step-shaped joint is formed between every two adjacent segments, so that the waterproof property of the joint is improved, and the segmental lining reinforcing type combined supporting structure is particularly applicable to tunnel construction under geological conditions of high ground stress and large deformation.

Description

technical field [0001] The invention relates to a segment lining support structure used in tunnel engineering, in particular to a segment lining reinforced combined support structure. Background technique [0002] Segment lining, as a kind of tunnel support structure, is assembled from prefabricated segments. The longitudinal direction of the tunnel is assembled by multi-ring assembled segment rings, and each ring segment is composed of a certain number of prefabricated reinforced concrete segments connected by ring bolts. Segment lining, as a kind of tunnel support structure, is widely used in tunnels constructed by shield tunneling method or TBM method because it can bear force immediately after being assembled into a ring and is conducive to mechanized construction. [0003] In recent years, with the continuous development of high-speed railways, there are more and more long and deeply buried railway tunnels. These railway tunnels are prone to encounter the adverse geolo...
