Production and installation
1. All metal parts must be galvanized, please protect the galvanized layer during operation.
2. The needle tip is made of galvanized steel pipe, the thickness of the tube wall shall not be less than 3mm, and the length of the needle tip brushed tin shall not be less than 70mm
3. The lightning protection tower should be installed firmly vertically. The allowable deviation of verticality is 3/1000.
4. Welding requirements Welding should be lap welding, and the lap length must meet the following requirements:
5. Flat steel is twice its width (and at least 3 edges are welded).
6. Round steel is 6 times its diameter.
7. When the round steel is connected to the flat steel, its length is 6 times the diameter of the round steel.
8. Lightning towers are generally made of round steel or steel pipes.
9 The lightning protection tower should be made of round steel or welded steel pipe.
Benefits of mountain tower construction:
1. Two fire-proof observation towers are built in the mountainous area, and the whole mountain can be seen, standing high and far away,
eliminating the blind spots of despair and saving a lot of manpower.
2. With fixed watch towers and indoor visits, the rangers can protect themselves from wind and sun on the one hand,
and they can also focus on forest fires on the other.
3. The construction of forest fire prevention observation towers will better reflect the policy of
“prevention first and active elimination”, to ensure the safety of people’s lives and property, and to protect mountain forest resources.
