Construction and use method of deicing and snow melting protection device for bridge stay cables

Abstract

The invention relates to the field of bridge auxiliary facilities, in particular to a construction and use method for a deicing and snow melting protection device for bridge stay cables. The technical problem to be solved by the invention is that the ice and snow covered on the stay cables in winter cannot be melted for a long time. In order to solve the above technical problems, the present invention provides a method for the construction and use of a deicing and snow melting protective device for bridge stay cables. Step 1: Use the elasticity of the PE pipe to assemble the PE pipe from top to bottom. Step 2: The inside of the first section and the last section of PE pipe has a reed limit device, turn the screw, let the screw pass the ball to initially fix the position of the PE pipe.

Description

technical field [0001] The invention relates to the field of bridge auxiliary facilities, in particular to a construction and use method for a deicing and snow melting protection device for bridge stay cables. Background technique [0002] De-icing of stay cables is one of the urgent problems in the industry. Whenever there is rain and snow in winter and the temperature continues to be below zero, the bridge stay cables are easily covered by rain and snow, and gradually condense into ice, forming icicles. In China, the problem of icicles falling from bridge cables has a long history: in 2015, some media reported the incident of icicles falling from Tianxingzhou Bridge in Wuhan; The glass of passing vehicles was smashed; during the same period, ice fell off the cables of the Bayi Bridge in Nanchang, and many vehicles were smashed, resulting in the temporary closure of the Bayi Bridge; A car was smashed and two people were injured. Afterwards, the Anqing Yangtze River Bridge...

AI Technical Summary

Problems solved by technology

[0003] It can be seen that the ice and snow covered on the stay cables in winter cannot be melted for a long time, and the impurities contained in the ice and snow are easy to corrode the stay cables. The block will be affected by external factors such as rising air temperature, wind blowing or normal vibration of the cable, causing the ice cube 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

[0004] 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.

[0005] 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
