Pavement deicing method based on laser confinement vaporization foamed polymer

Abstract

The invention provides a road surface ice removing method based on a laser confinement gasified and foamed polymer. The road surface ice removing method comprises the following steps: (1) coating one layer of foamed organic polymer coating on an unfrozen road surface in advance; (2) when an ice layer covers the road surface and the ice layer is not rolled by a machine, outputting a pulse laser beam so as to enable the laser beam to penetrate through the ice layer to be focused on the foamed organic polymer coating of the road surface; releasing a solid-state attachment force between the ice layer and the foamed organic polymer coating; (3) transversely moving a focusing position of the laser beam, wherein a certain distance is formed between scanning tracks; (4) controlling the laser beam to move forward for a certain distance and then returning back to the step (3) to carry out transverse scanning; (5) repeatedly carrying out the step (4) to enable the ice layer on a region scanned by laser on the road surface to be crushed; and (6) removing crushed ice blocks through a traditional snow sweeping shovel car. According to the road surface ice removing method provided by the invention, the laser has no influence on the road surface in an ice removing process through utilizing smelting point difference between a common cement or stone path and a coating material, and lossless ice removal is realized.

Description

technical field [0001] The invention belongs to the field of laser applications, and in particular relates to a road surface deicing method based on laser-constrained vaporization and foaming polymers. Background technique [0002] In winter, bridges, sidewalks, park squares and other public places in northern my country often freeze, which affects traffic safety and easily causes pedestrians to fall and other accidents. [0003] In order to eliminate ice and snow hazards and ensure road traffic safety, some effective prevention and removal methods of road ice and snow have been researched and applied at home and abroad, which can be roughly divided into manual removal, deicing agent removal, mechanical removal, thermal snow melting, and intelligent anti-icing and deicing systems. And pavement coating deicing and other categories.

Problems solved by technology

At present, the traditional manual mechanical deicing method has been difficult to meet the needs of current traffic construction and social development. The construction of informatization and intelligent traffic safety guarantee system will be the future development trend of my country's transportation safety and emergency guarantee field.

Although the new intelligent anti-icing and deicing system can better achieve the effect of actively preventing and controlling ice and snow, its cost and technical reasons restrict the possibility of large-scale promotion and use.

Pavement coating technology is simple in construction, low in cost, and has little impact on the road surface and the environment, but its deicing effect is not good
