The fire watch tower is a core monitoring facility in the forest fire prevention system, primarily designed with a four-column steel frame structure. The tower is constructed using Q235 low-alloy high-strength steel, equipped with a rotating ladder, work platform, and lightning protection device. It is treated with hot-dip galvanizing for corrosion protection, ensuring a service life of over 30 years.  The observation radius extends up to 15 kilometers, enabling early warning of forest fires and reducing the pressure on manual patrols. Experts' research on the observation tower shows that this facility effectively complements the integrated "sky, air, and ground" monitoring network. The tower combines observation and command functions with tourism and sightseeing value, but it has technical limitations such as restricted observation during thunderstorms and blind spots due to terrain.

Structural Design

The tower is composed of an angular steel structure with four pillars, featuring steel plate thickness of 10-30mm, connected by a combination of bolts and welding.

Equipped with a rotating ladder, double-layered guardrails, a working platform, and a sealed observation room, with a lightning rod installed at the top [4]

The foundation is based on a deep burial concrete technique, with a soil bearing capacity requirement of 100-200 KN/m² and a verticality deviation of ≤1/1000.

Functional Applications

• Wildfire Monitoring: Forest rangers can observe a 15-kilometer radius forest area from a high vantage point, and immediately issue an alert upon detecting smoke. 。
• Auxiliary Decision-Making: As a fire command node, provides fire location and situation assessment support 。
• Environmental Monitoring: Some towers are integrated with meteorological sensors and video monitoring equipment. 。
• Derived Functions: Mountainous observation towers serve both as tourist attractions, with two towers covering the entire area.。

Technical Specifications

• Design Standards: Wind resistance up to 30 m/s, seismic resistance of 8 degrees, and ice coating thickness of 5-10 mm. 。
• Environmental Adaptability: Operating temperature -35℃ to 45℃, Ground resistance ≤4Ω。
• Safety Factor: Structural design safety factor of 4-5 times, wind resistance of over 12 levels。

Establish and maintain

Site Selection Requirements: Located at a high point in the mountainous terrain to ensure a full panoramic view without blind spots.

Construction Specifications: Strictly adhere to steel structure design standards; installation requires layer-by-layer assembly and acceptance.

Maintenance System: Comprehensive inspection of tower structure safety and communication equipment status prior to fire prevention period

Inspection Cycle: Regular checks for galvanized layer corrosion and bolt tightness

Technical Limitations

Observation Blind Spots: There are monitoring dead zones in areas with undulating terrain.

Weather Constraints: Use suspended due to severe weather such as thunderstorms, heavy fog, etc.

Human Dependence: Accuracy of fire detection is directly related to the lookout's experience.

Response Delay: Requires manual verification of on-site conditions after fire detection
