[0002] With the continuous development of the transportation network, the number of vehicles has increased, resulting in more congested roads. As a result, many roads have been expanded. When encountering mountains, people have resorted to building tunnels to construct roads. To enhance the aesthetics of the tunnel, decorative panels are installed on the side walls of the tunnel. However, the existing side decorative panels use fiber cement pressure plates, an A1-grade fireproof material, as the base material, which has insufficient fireproofing performance. In addition, the decorative panels have multiple splicing locations, making splicing difficult and inefficient. Furthermore, since electrical components such as monitoring, ventilation, and lighting are installed in the tunnel, the pipeline layout of each electrical component is relatively messy and lacks standardized management. When problems arise in the pipelines, the subsequent maintenance and troubleshooting process is very inconvenient and labor-intensive. Summary of the Invention

This spliced ​​decorative base plate 2 is a 5mm thick decorative plate. The inner side wall of the tunnel 1 is pre-embedded with slots 5 for securing the upper and lower ends of the decorative plate. The upper and lower ends of the spliced ​​decorative base plate 2 are disposed within these slots 5. In this specific embodiment, the slots 5 for securing the upper and lower ends of the decorative plate are inclined slots, made of steel bars welded to pre-embedded steel bars, or one end of the steel bar is pre-embedded in the tunnel concrete. The inclined slots, at a certain angle, facilitate a more secure attachment of the spliced ​​decorative base plate. Each of the spliced ​​decorative substrates 2 has a boss 3 in the middle of one side and a splicing groove 4 on the other side that mates with the boss 3. The boss 3 has inclined first anti-slip surfaces 3-1 at both ends, and the splicing groove 4 has second anti-slip surfaces 4-1 at both ends that mate with the first anti-slip surfaces. The addition of the first anti-slip surfaces 3-1, relative to the smooth bosses, effectively prevents the bosses from slipping out of the grooves. The spliced ​​decorative substrates 2 only need to have bosses and splicing grooves on both sides, meaning there is only one splicing location, facilitating splicing and improving work efficiency.

[0033] The spliced ​​decorative substrate 2 is a hollow structure, and multiple groups of pipeline through-holes are provided in the hollow structure of the spliced ​​decorative substrate 2, and the wires are passed through each pipeline through-hole. In this specific embodiment: an insulating tube 6 is provided in each pipeline through-hole of the spliced ​​decorative substrate, and the insulating tube 6 is divided into two sections, and there is a spacing between the two sections of the insulating tube 6. The spacing corresponds to the inspection hole. This spacing is convenient for inspecting the pipeline and also for threading the wires when installing the pipeline. The tunnel wall side surface of the spliced ​​decorative substrate 2 is provided with a flame-retardant asphalt coating 9, and the flame-retardant performance of the decorative board is improved by the flame-retardant asphalt coating. The outer surface of the spliced ​​decorative substrate 2 is provided with a fire-resistant decorative material layer 8, and the fire-resistant decorative material layer 8 includes a fluorocarbon paint coating and a pigment layer. The fire-resistant decorative material layer 8 is provided with an inspection hole. During inspection, the inspection hole is used to check whether each group of pipelines is normal, so as to quickly find out the line problem and troubleshoot. The inspection hole is provided with a protective door 7, which is equipped with a lock. The lock is a locking plate 11, which is hinged to the protective door 7, resulting in a simple structure. In this specific embodiment, two locking plates are hinged at the upper and lower ends of the protective door 7. The locking plates are provided with protrusions, which facilitate the rotation of the locking plates. The protective door is locked and opened by rotating the position of the locking plate 9. When the locking plate 11 contacts the spliced ​​decorative baseboard, the protective door is locked. When the locking plate 11 separates from the spliced ​​decorative baseboard, the protective door is opened, resulting in a simple structure. Specific embodiment 2:
