Problems solved by technology

However, at the longitudinal connection of the arch frame, the steel bars only play the role of longitudinal connection, and there is a lack of support in the longitudinal direction of the arch frame. Large settlement or even "closed door collapse" is likely to occur in these parts
[0003] In view of the existing technical problems, it is necessary to design a new type of arch to solve the problem that the existing arch cannot play a supporting role in the longitudinal direction

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

[0026] Such as Figure 1-4 Shown is a highway tunnel heterogeneous arch, which is a ring-toward closed structure composed of an upper arch and a lower arch.

[0027] The lower arch is a U-shaped structure with the opening side facing upwards, and the upper arch is arranged on the upper part of the lower arch.

[0028] The shape of the upper arch matches the top of the tunnel. It is an arc-shaped structure. The upper arch is composed of a continuous wave curve. The wave curve is composed of multiple single wave curves with the same structure. The vertical line from the peak to the valley Parallel to the extension direction of the tunnel, the two ends of the upper arch are located at the center of the wave height, and the two ends of the upper arch are respectively connected with the two ...

Abstract

The invention discloses a highway tunnel irregular arch frame of a circumferential closed structure and including an upper arch frame and a lower arch frame. The lower arch frame is of a U-shaped structure with an opening upward; the upper arch frame is used for supporting the top of a tunnel, the upper arch frame is a continuous waveform curve, and the extension direction of the waveform curve isthe width direction of the tunnel. The waveform curve is formed by a plurality of single-wave curves with the same structure, a vertical line from the peak to the trough is parallel to the extensiondirection of the tunnel, and the two ends of the upper arch frame are respectively connected to the two ends of the lower arch frame. The arch frame increases longitudinal connection between arch frames during the tunnel composite lining preliminary supporting, the arch frame is longitudinally bent, the annular supporting range of the arc frame is increased, the arch frame local supporting rigidity and the overall combined supporting stability are improved, and the construction risk caused by large difference in tunnel longitudinal stress can be reduced.

Description

technical field [0001] The invention relates to the technical field of road tunnel construction, in particular to a special-shaped arch frame of a road tunnel. Background technique [0002] At present, the arch frame in the initial support of the composite lining of the tunnel adopts a single ring to form a ring, and uses steel bars to connect in the longitudinal direction to strengthen the surrounding rock to resist large deformation of the surrounding rock. However, at the longitudinal connection of the arch frame, the steel bar only plays the role of longitudinal connection, and there is a lack of support in the longitudinal direction of the arch frame. Large settlement or even "closed door collapse" is easy to occur in these parts. [0003] In view of the existing technical problems, it is necessary to design a new type of arch to solve the problem that the existing arch cannot play a supporting role in the longitudinal direction. Contents of the invention [0004] Ai...
