the rainwater and the condensate water that permeate into steel-pipe pole 1 inside fall into catchment chamber 4 on catchment piece 2, outside discharging the rainwater 1 steel-pipe pole through drain pipe 6, can avoid inside long-term ponding at the bottom of steel-pipe pole 1 from this to lead to the corrosion damage, influence the design life and the structural strength of steel-pipe pole 1, eliminate the fracture of steel-pipe pole root and the safe risk that appears toppling. It is worth noting that the outer wall of the drain pipe 6 and the inner wall of the water outlet 5 are sealed by welding, so that rainwater is prevented from directly entering the bottom of the steel pipe pole 1 through a gap between the drain pipe 6 and the water outlet 5, and the bottom of the steel pipe pole 1 is prevented from being rusted and damaged.
As shown in fig. 1 and 2, the ventilation member 3 includes a ventilation steel pipe 7, a waterproof cover 8 and a flange plate 9, the ventilation steel pipe 7 is a hollow structure, one end of the ventilation steel pipe 7 is fixed with the waterproof cover 8, the other end is fixed with the flange plate 9, a plurality of ventilation openings 10 extending along the longitudinal direction are formed in the pipe wall of the ventilation steel pipe 7, the ventilation openings 10 are arranged close to the waterproof cover 8, the waterproof cover 8 is of an umbrella-shaped structure, the diameter of one end of the large diameter of the waterproof cover 8 is larger than that of the flange plate 9, one end of the large diameter of the waterproof cover 8 extends to the bottom of the ventilation openings 10, and the ventilation member 3 is connected with the flange plate 1 through.
When being in rainwater weather for a long time or the temperature is lower, can adhere to rainwater or liquefaction on the inner wall of steel-pipe pole 1 and have the raindrop, and the ventilation capability of current steel-pipe pole 1 is poor again, can lead to the fact the corrosion to the inner wall of steel-pipe pole 1 for a long time, seriously influences the intensity of steel-pipe pole 1, causes the fracture of steel-pipe pole 1, causes the incident and causes economic loss. While the ventilation member 3 of the present application effectively avoids this. Because the ventilation piece 3 sets up the top at steel pipe pole 1, the height of steel pipe pole 1 is generally higher, therefore the wind-force at steel pipe pole 1 top is great, communicate with each other through vent 10 and the inside of steel pipe pole 1, make steel pipe pole 1 have better ventilation effect, the quick drop of water to on the inner wall of steel pipe pole 1 air-dries, avoid the inner wall of steel pipe pole 1 to receive the corrosion, the life of steel pipe pole 1 has been increased, including the water shield 8 shields vent 10 simultaneously, effectually prevented that the rainwater from entering into in the steel pipe pole 1 from vent 10, the diameter of water shield 8 is greater than the diameter of ring flange 9, has the effect that prevents that ring flange 9 from receiving the rainwater erosion.
Further, the steel pipe pole 1 comprises a main steel pipe 11 and a branch steel pipe 12, wherein flanges a13 are welded to one ends of the main steel pipe 11 and the branch steel pipe 12, the branch steel pipe 12 is connected with the main steel pipe 11 through a flange a13, a ventilation part 3 is arranged at the other end of the branch steel pipe 12, a water collection part 2 is welded to the inner wall of the main steel pipe 11, and the water collection part 2 is arranged close to the branch steel pipe 12.
