Bridge-tunnel connecting segment anti-freezing system based on semiconductor laser technology

Abstract

The invention discloses a bridge-tunnel connecting segment anti-freezing system based on a semiconductor laser technology. The bridge-tunnel connecting segment anti-freezing system comprises a tunnel,a beam body, bridge piers, semiconductor lasers, a driving power supply, a control room, transmission cables, a freezing zone and a sidewalk; an arch ring of the tunnel is connected with the beam body, the beam body is supported by the bridge piers, the transmission cables and a plurality of semiconductor lasers are embedded in concrete of the sidewalk of the beam body, the transmission cables and the plurality of semiconductor lasers are in parallel connection, the semiconductor lasers embedded in the sidewalk are not completely closed, a front radiation zone is exposed and capable of irradiating laser into the freezing zone, the semiconductor lasers are connected with the distant driving power supply through the transmission cables, the driving power supply is placed in the control room, and the driving power supply can be manually powered on in the control room. By adopting the bridge-tunnel connecting segment anti-freezing system based on the semiconductor laser technology, the freezing on a bridge deck can be prevented and removed under low-temperature humid and easily-freezing conditions.

Description

Technical field [0001] The invention belongs to the field of bridge deicing, and in particular relates to a bridge-tunnel connecting section bridge anti-icing system based on semiconductor laser technology. Background technique [0002] For bridge projects in low-temperature, humid and rainy areas in winter, because the bridge deck is suspended in the air, and the bridges connecting bridges and tunnels are often located at the valley vents, when the external temperature in winter is below zero degrees Celsius, it is easy to cause the bridge deck to freeze. Cause a safety incident. Existing deicing machinery will obstruct traffic while working. Therefore, it is necessary to design a deicing technology that can clear bridge icing without affecting traffic. Summary of the invention [0003] Purpose of the invention: In view of the above problems, the present invention proposes a bridge-tunnel connecting section bridge anti-freezing system based on semiconductor laser technology. The...

Problems solved by technology

[0002] For bridge projects in low temperature, humid and rainy areas in winter, since the bridge deck is suspended in the air, and the bridges connecting bridges and tunnels are often located at the valley vents, when the outside temperature in winter is below zero degrees Celsius, it is very easy to cause the bridge deck to freeze. cause security incident

Existing deicing machinery will hinder traffic while working, so it is necessary to design a deicing technology that can remove ice from bridges without affecting traffic
