A kind of road and its construction method

Abstract

The invention relates to a road and its construction method, and relates to the technical field of municipal road construction. The surface of the leveling layer is covered with a sand-blocking net, and the surface layer includes a permeable brick, and the permeable brick is located above the sand-blocking net. The present invention can effectively slow down the formation of voids.

Description

Technical field [0001] The present invention relates to the technical field of municipal road construction, in particular, involving a road and its construction methods. Background technique [0002] The pedestrian road is one of the municipal roads. When laying a walk, it usually includes laying layers, find flat layers, base and base layers. Among them, the layers are generally sand, and the layers are generally used in water-impermeable bricks, and the water tiles are generally clay tiles, concrete water-absorbing bricks, sand-based water tiles and ceramic water mesh bricks; where clay tiles can, and surface can be subtle, but After the moisture absorbs saturation, it will overflow from the brick surface. After a long time is used, the brick surface is easy to moss, resulting in a brick surface; and the concrete water-absorbent brick is in the same material, the greater the pores, the higher the water permeability, corresponding The lower the intensity, the high-permeability a...

AI Technical Summary

Problems solved by technology

The leveling layer is generally a sandstone layer, and the paving layer is generally made of permeable bricks. The permeable bricks generally include clay bricks, concrete permeable bricks, sand-based permeable bricks and ceramic permeable bricks; among them, the clay bricks have good strength and can slightly absorb water on the surface, but After the moisture is absorbed and saturated, it will overflow from the brick surface. After a long time of use, the brick surface will be prone to moss, causing the brick surface to be very slippery; while the concrete permeable brick has larger pores in the same material, and the higher the water permeability, the corresponding The lower the strength, it is difficult to achieve high water permeability and high strength at the same time; while the sand-based permeable brick (silica sand) has good water permeability. It is made of sand and resin glue, but it is easy to be air-dried and the strength is not enough. Therefore, the service life is too short; and the ceramic permeable brick has high strength and good water permeability, but the price is high, and it is uneconomical to use in a large area. In addition, stone materials such as granite have strength, do not fade, and are difficult to weather, but they are impermeable, so they cannot be called Permeable brick

[0003] The existing technical solutions mentioned above have the following defects: Therefore, in rainy weather, the rainwater will seep down to the leveling layer along the permeable bricks. A cavity is formed, and rainwater will accumulate in the cavity. When the permeable brick is under a certain pressure, it will sink into the cavity, so that the rainwater in the cavity will splash and dirty the clothes of pedestrians.
