[0002] Tunnels are engineering structures buried underground, representing a form of human utilization of underground space. They are primarily used for transportation, water conservancy, and municipal purposes. Pre-embedded channels, as components supporting the overhead contact line in high-speed railway tunnel construction, are a crucial part of the tunnel construction process. These channels are pre-embedded in concrete and used to secure the overhead contact line, communication signal equipment, and electrical equipment. Because pre-embedded channels greatly facilitate the installation of subsequent equipment and pipelines, improve construction efficiency, and reduce construction costs, they offer significant economic benefits. In recent years, the installation of pre-embedded channels in tunnels has been widely adopted, providing a reliable foundation for the installation of overhead contact lines in high-speed railway tunnels and ensuring the safe operation of high-speed trains.

[0003] Existing tunnel channel pre-installation methods are inconvenient to adjust and set, resulting in long installation and positioning times and high costs, causing inconvenience to users. Therefore, we propose a tunnel channel pre-fixing device. Utility Model Content
