Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of composite material electric poles, in particular to a composite material electric pole and a bending-resistant reinforcing device thereof. BACKGROUND

[0002] Fiber-reinforced composite material is a kind of composite material composed of resin and fiber-reinforced material, which has the advantages of high specific strength and specific stiffness, good fatigue resistance, excellent corrosion resistance, light structure weight, long service life, etc., and is an ideal material for power transmission towers.

[0003] In practical applications, the transportation of reinforced concrete or steel pipe whole poles is difficult and costly, especially in mountainous areas where vehicles and machinery cannot be used. Currently, the connection between composite material round pipes is achieved by bolted flange connection. The bolted flange connection is achieved by tightening the flanges at the ends of two round pipes with bolts. However, the cross-section bending stiffness of the round pipe connection is low, which easily leads to a decrease in the bending resistance of the top end of the electric pole.

[0004] The existing composite material electric poles are difficult to enhance the cross-section bending stiffness of the round pipe connection to reduce the deflection of the assembled electric pole top end only by bolted flange connection. At the same time, when installing the composite material electric pole, it is usually installed at the bottom of the horizontal ground, and then pressed by the soil layer or poured with concrete. However, when it is applied in heavy rain and strong wind weather conditions, the soil becomes soft due to the soaking of heavy rain, and combined with the strong wind, it is easy to cause the displacement or bending of the electric pole. It is difficult to further reinforce the bottom and interior of the electric pole and enhance the bending resistance of the composite material electric pole in heavy rain and strong wind weather.
