Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering technology, and in particular to a tunnel route and pipeline layout structure. Background Technology

[0002] With the widespread application of tunnel engineering in transportation, energy transmission, and other fields, the rational layout of lines and pipelines within tunnels is crucial to ensuring the safe and stable operation of tunnels. However, current tunnel construction and operation face numerous technical challenges and difficulties.

[0003] On the one hand, tunnels typically require the installation of various functional pipes and lines, such as ventilation ducts, water pipes to meet construction and operational water needs, and lines for power transmission and signal transmission. However, traditional layout methods often lack systematic planning, leading to mutual interference between pipes and lines, which not only increases the difficulty of installation and maintenance but also poses safety hazards.

[0004] On the other hand, the design of escape routes is crucial for the evacuation of personnel in the event of a tunnel accident. However, in actual engineering projects, escape routes often suffer from low evacuation efficiency due to space constraints or improper layout. Some tunnel escape routes conflict with other facilities, making it difficult to ensure the rapid and safe evacuation of personnel and seriously threatening the safety of life and property.

[0005] Furthermore, the humid and complex environment inside the tunnel places higher demands on the support structure for pipelines and lines. Traditional support components may suffer from insufficient strength and poor corrosion resistance, leading to pipelines and lines loosening and falling off, thus affecting the overall stability of the tunnel.
