AI Technical Summary

Technical Problem

Existing technologies have poor ice and snow compaction effects in the construction of polar ice and snow runways, especially at the bottom where compaction is insufficient. Furthermore, in low-temperature environments, snow easily forms distinct ice crystals, making compaction difficult.

Method used

A progressive road compaction device is adopted, including a movable vehicle, a snow-breaking device, and a snow-pressing device. Snow-breaking shovels and compaction wheels of different heights are used to compact ice and snow layer by layer, and a heating device is used to increase the hardness of the ice layer. A grinding device is used to ensure the smoothness.

Benefits of technology

This has enabled effective compaction of icy and snowy roads, ensuring safety and flatness, and improving the quality of use of icy and snowy running tracks.

Abstract

This application relates to the field of polar runway construction, specifically disclosing a progressive road compaction device and method for compacting polar ice and snow. The device includes a movable vehicle body with a snow-breaking device and a snow-pressing device installed at the bottom. The snow-breaking device includes a snow-breaking frame that is raised and lowered at the bottom of the vehicle body, with a drive cylinder at the bottom. Two snow-breaking chambers are formed within the snow-breaking frame, and a first snow-breaking shovel and a second snow-breaking shovel are respectively installed near the ground openings of the two snow-breaking chambers. The first snow-breaking shovel is higher than the second snow-breaking shovel. A snow-transporting chamber connected to the two snow-breaking chambers is also provided within the snow-breaking frame. Both the snow-breaking chamber and the snow-transporting chamber are equipped with conveying devices for transporting ice and snow. The snow-pressing device includes multiple compaction wheels rotatably connected to the bottom of the vehicle body. The height of the compaction wheels gradually increases in the direction away from the snow-breaking frame, and snow-falling chambers are formed between adjacent compaction wheels. The snow-transporting chamber is connected to the multiple snow-falling chambers. This application has the effect of improving the compaction density of ice and snow runways.
