A deicing and snow melting protective device for bridge stay cables

Abstract

The invention discloses a deicing and snow-melting protection device for bridge stay cables, comprising a PE pipe, the inner surface of the PE pipe is fixedly connected with a water-absorbing expansion device, and the inner surface of the water-absorbing expansion device is fixedly connected with a waterproof film , the interior of the waterproof film is provided with longitudinal slots, and a self-controlling temperature heating cable is spirally connected between the outer surface of the water-absorbing expansion device and the inner surface of the PE pipe. Water vapor isolation can achieve anti-corrosion, waterproof and anti-rust effect of the cable stay, increase the life of the cable stay, the water absorption expansion device can absorb the melted snow water to increase the volume, expand outward from the nozzle, stress break the ice, the opening of the PE pipe is set, The water vapor generated by the evaporation of the water surface around the stay cable can be absorbed. When the temperature is high, the device can be used to dehumidify in summer, protect the stay cable and prolong the life of the stay cable.

Description

technical field [0001] The invention relates to the field of bridge auxiliary facilities, in particular to a stay cable deicing and snow melting protection device. Background technique [0002] The ice and snow covered on the stay cables in winter cannot be melted for a long time. The impurities contained in the ice and snow are easy to corrode the stay cables. The ice and snow itself also increases the load of the stay cables. External factors such as ascent, wind blowing or normal vibration of the cable cause the ice to fall from the cable. When the ice at a higher position falls, due to the high speed, it will pose a major safety hazard to the vehicles running normally on the bridge deck. In severe cases, it will even cause a series of traffic accidents, causing huge personal and property losses. Normal travel is affected. [0003] The heating devices used in existing cable-stayed deicing devices are mainly heating cables, but the heating area is limited. If the winding...

[0002] The ice and snow covered on the stay cables in winter cannot be melted for a long time. The impurities contained in the ice and snow are easy to corrode the stay cables. The ice and snow itself also increases the load of the stay cables. The impact of external factors such as ascent, wind blowing or normal vibration of the cable causes the ice to fall from the cable

When the ice at a higher position falls, due to the high speed, it will pose a major safety hazard to the vehicles running normally on the bridge deck. In severe cases, it will even cause a series of traffic accidents, causing huge personal and property losses. impact on normal travel

[0003] The heating device used in the existing cable-stayed deicing device is mainly heating the heating cable, but the heating area is limited. If the winding is too dense, the material of the heating cable will be wasted, and the effect of loose winding and deicing and snow melting will be uneven, which will easily cause secondary freezing

Moreover, after the ice and snow are melted by the self-controlling heating belt used in the existing bridge, the snow water directly drips or slides down along the stay cables, and lacks a collection device, resulting in waste
