Self-snow-melting water-permeable water-collecting integral pavement

Abstract

The invention discloses a self-snow-melting water-permeable water-collecting integral pavement, which comprises a low freezing point protective agent coating, a low freezing point color surface layer,a low freezing point primary color bottom layer, a coarse sand leveling layer, a graded gravel layer and a plain soil layer which are sequentially arranged from top to bottom. A water collecting device is also arranged at the middle lower part of the graded gravel layer. an environment-friendly low freezing point material is mixed with concrete and a protective agent material, to form the low freezing point protective agent coating, the low freezing point color surface layer and the low freezing point primary color bottom layer, so that a snowy road is frozen in winter, snow water quickly infiltrates after being melted, snow on the road surface is continuously melted, the whole snow melting process is accelerated, and potential safety hazards caused by snowing and freezing are eliminated.The low freezing point material is combined with a water guide pipe, so that the infiltrated snow water is effectively drained, a base layer is protected from the corrosion of salinized substances, and rainwater can be recycled and purified.

Description

technical field [0001] The invention relates to a pavement structure, in particular to a self-melting snow-permeable water-collecting integral pavement, which belongs to the technical field of road engineering. Background technique [0002] Ordinary permeable roads cannot guarantee the safety of road driving under the conditions of snowfall and freezing in the north. It is necessary to use mechanical deicing agents and mechanical snow plows to remove ice and snow on the road surface. This method is easy to cause damage to the road surface. The deicing agents currently used on asphalt pavement have a certain corrosion effect on the pavement, and have certain damage to the surrounding ecological environment, and the cost is relatively high. [0003] The current snow melting materials are mainly composed of salts, which precipitate and accumulate in the foundation with rainwater seepage, which easily causes soil salinization; traditional permeable pavement cannot effectively dr...

AI Technical Summary

Problems solved by technology

[0003] The current snow-melting materials are mainly composed of salts, which precipitate and accumulate in the foundation with rainwater seepage, which is likely to cause soil salinization; traditional permeable pavement cannot effectively drain the surface water of the foundation, and the soaked foundation often collapses The sinking causes the road surface to be damaged and brings safety hazards, and the utilization rate of rainwater is low, which wastes a lot of water resources and cannot meet the needs of the country to build a sponge city

Ordinary permeable roads cannot guarantee the safety of road driving under the conditions of snowfall and icing in the north, and traffic obstacles often occur and are unavoidable
