Intelligent automatic snow melting and deicing bridge deck pavement system

Abstract

The invention discloses an intelligent automatic snow melting and deicing bridge deck pavement system. The system comprises a pavement upper layer, a pavement lower layer and a concrete slab layer which are laid in order from top to bottom, a steel wire mesh is arranged between the pavement upper layer and the pavement lower layer, and a heating wire is paved on the steel wire mesh; a data receiving controller and a digital temperature control switch are connected between the heating wire and a power grid, a temperature sensor is arranged in the pavement upper layer, and the data receiving controller collects the road surface temperature through the temperature sensor. When the road surface temperature exceeds a set threshold, the data receiving controller controls the digital temperaturecontrol switch to be turned on for supplying power to the heating wire to realize the road surface heating. Through intelligent power supply control on a converge cabinet through the digital temperature control switch connected with the data receiving controller, the electric heating snow melting system is high in heating speed, high in heat supply stability, has a good effect of melting snow anddeicing, and does not cause pollution and damage to the environment and the road surface; and the whole system does not need manual on-site participation during operation, reducing the labor cost, andimproving the work efficiency.

Description

technical field [0001] The invention belongs to the field of road engineering, and relates to a bridge deck pavement system, in particular to an intelligent bridge deck pavement system for automatically melting snow and ice. Background technique [0002] The snow and ice on the bridge deck in winter seriously restricts the operation of road traffic, especially in severe cold areas, where a large amount of snowfall, freezing rain and other bad weather make the bridge deck freeze and cause great safety hazards to driving. The ice layer attached to the surface of the bridge pavement layer lasts for a long time. On the one hand, it reduces the friction coefficient of the road surface, reduces the adhesion between the tire and the ground, increases the difficulty of driving operation control, and seriously threatens the safety of drivers and passengers. Safety of life and property. On the other hand, successive traffic accidents have seriously hindered the smooth operation of th...

Problems solved by technology

[0003] At present, the traditional method of melting snow and ice on the bridge deck at home and abroad is to spread ice-melting salt. This method is simple to operate and has good effect. The source of ice-melting salt material is wide, the price is low, and the speed of snow melting is fast. It is the most widely used bridge at this stage. However, the special corrosiveness of salts will cause serious pollution and damage to the environment and structures around the bridge, which is contrary to the theory of green environmental protection, and spreading ice-melting salt in busy traffic will also harm workers. self-safety hazard
