Mechanical strength analysis of lighting poles
The lighting pole design must have sufficient mechanical strength requirements: ambient temperature -40e-40e, ambient wind speed 40-50mPs, anti-seismic level 8 and corrosion resistance for 30 years. All metal structural parts of lighting equipment shall be treated by hot dip zinc anti-corrosion process. All fasteners shall be made of stainless steel or galvanized material. The thickness of hot-dip galvanized galvanized layer shall be greater than 86Lm, and the surface of pole of hot rod after hot dip galvanizing The zinc layer should be smooth, uniform, firm, burr-free, and free from dandruff. The civil engineering design of road lighting engineering includes basic design. The basic requirements of street lighting have certain impact resistance and wind resistance. It is required to design according to the geological data of the site and the local basic wind pressure value. The basic requirements of the street lamp have a certain volume and depth of burial. To meet the requirements. Road lighting is generally buried by cable. When crossing the road, a protective pipe is required. The protective pipe should be made of streetlight-specific power pipe or galvanized steel pipe instead of ordinary plastic pipe to avoid flattening or crushing during construction. It causes trouble for future threading and maintenance. If the lighting cable is installed in the green belt, it is best to wear the tube protection to prevent the cable from being damaged by the green crop or the cable construction and maintenance damage to the greening. The safety of road lighting systems is a problem that must be taken very seriously. Since the lamp poles are generally made of metal and exposed directly to the outside, sufficient measures should be taken to ensure the safety of electricity. Each street lamp should be provided with a separate short circuit protection, which is generally implemented by a fuse provided in the lamp holder.
