Description

Technical Field

[0001] The utility model relates to the technical field of existing tunnel reconstruction, in particular to a detachable assembled wall system for an existing tunnel. Background Art

[0002] Urban renewal is accelerating and is in the stage of full-chain renewal. Urban traffic pressure is becoming increasingly severe, and various facilities are aging, which seriously affects the development of urban traffic operations. Tunnel renovation is also an important part of it. In the renovation project, efficient renovation can minimize the impact on the existing environment during the renovation process. Prefabricated buildings and components have been widely used in recent years due to their excellent characteristics such as high efficiency, high precision, and good structural seismic resistance. The modular production of prefabricated parts, the rapidity of overall assembly, and the effective control of construction accuracy provide strong support and guarantee for the promotion and use of prefabricated buildings. Analogous to the prefabricated structural system, the renovation of prefabricated tunnel walls is also an important part of the prefabrication, and its application in various linear renovation projects is becoming more and more extensive. And with the development of various new materials and new processes, the diversified selection of decorative surface layers and the convenience of maintenance and repair have become the norm, and the fast installation system of prefabricated decoration and renovation can better meet such needs.

[0003] When decorating the walls of traditional tunnel projects, paint is usually applied on the original concrete wall or the traditional layered keel surface is used. For the use of paint for construction, the flatness of the original concrete wall is required to be high, and the subsequent maintenance is difficult. The environment in the tunnel is poor, which can easily cause wall pollution or damage. The repaired paint wall often has a large color difference. The layered keel surface process is complicated, and there are many riveting and welding processes, which are slow. During the tunnel renovation construction process, traffic needs to be restored quickly to reduce the impact on the surrounding environment and tunnel operations.

[0004] In the later tunnel maintenance process, if a traffic accident occurs in the tunnel and the wall decoration surface is damaged, the traditional layered keel surface cannot be quickly disassembled and replaced, which will have a certain impact on traffic operation. At the same time, because the layered keel surface needs to be riveted or welded, when the surface is damaged, the keel cannot be reused, which often causes waste of materials and energy. In addition, it is subject to the influence of external environmental factors and cannot meet the requirements of rapid recovery. Although the traditional layered keel surface, keel and panel can meet the process requirements of the surface, there are certain limitations when using it in tunnels with large curvature and slope. The adjustment room of the layered keel is very small, and it is also a great test for the operation level of construction workers. Summary of the invention

[0005] In view of the above-mentioned existing technologies, in order to ensure that the tunnel wall renovation project is fast, economical, environmentally friendly, high-quality, recyclable, and convenient for later maintenance while minimizing the impact on tunnel operations, and to solve the problems of low adaptability of tunnel wall renovation and decoration, inability to be disassembled and reused, and inconvenient maintenance, the utility model proposes a detachable assembled wall system for existing tunnels.

[0006] The utility model provides a detachable assembled wall system of an existing tunnel, comprising a decorative surface layer, wherein the decorative surface layer is composed of a plurality of panels, both sides of the panels are connected to the wall of the existing tunnel through mounting brackets, the mounting brackets comprise U-shaped hollow seam keels, the closed side of the U-shaped hollow seam keels is fixedly connected to the wall of the existing tunnel through a plurality of connectors, the open side of the U-shaped hollow seam keels is provided with hollow seam cover plates, the U-shaped hollow seam keels are provided with hanging grooves, the panels are provided with hanging plates, and the hanging plates are snap-connected to the hanging grooves.
