Description

Technical Field

[0001] The invention discloses a shield tunnel walkway which is convenient and quick to install and is used for the tunnel walkway, belonging to the technical field of the tunnel walkway. Background Art

[0002] The installation of tunnel walkways in the prior art is a complex process involving multiple steps and technical requirements. Specifically, before the installation of the tunnel walkway, a detailed geological survey is required to understand the geological conditions of the tunnel, including rock types, groundwater conditions, etc., in order to determine the appropriate construction methods and support measures. Design the layout, support structure and material selection of the walkway according to the size, shape and geological conditions of the tunnel. Before installing the walkway, it is necessary to clean up the debris, accumulated water, etc. in the tunnel to ensure a clean construction environment. Set up temporary brackets or scaffolding in the tunnel to facilitate construction workers to work. Lay the foundation structure of the walkway in the tunnel, including laying a concrete base or using special cushioning materials. Install the main structure of the walkway according to the design requirements. Including metal brackets, metal plates, etc. For modularly designed walkways, this step may be relatively quick and simple. Ensure that the various parts of the walkway are firmly connected, using bolts, welding or other fixing methods to ensure the stability of the structure.

[0003] Although the installation of tunnel walkways in the prior art has achieved modular installation, the following technical problems still exist:

[0004] Fixing the metal plate to the metal bracket by passing a steel wire through the filter holes on the metal plate can easily cause an uneven walkway surface, resulting in safety issues such as tripping, or unstable fixation, with one side being stressed and the other side warping.
