Water permeable pavement

Abstract

The invention relates to water permeable pavement and foundation pavement using water permeable bricks. The water permeable pavement comprises a leveling base layer, a foundation pavement layer and a water permeable brick layer which are arranged sequentially from bottom to top, wherein the foundation pavement layer is formed by sequentially laying of a plurality of water permeable foundation bricks, and the water permeable brick layer is formed by laying of the multiple water permeable bricks. Water collecting grooves are pre-buried in the two sides of the leveling base layer and the foundation pavement layer in the length direction correspondingly, and openings of the water collecting grooves face the foundation pavement layer. According to the pavement, road beds are the same in hardness, the integrality is high, cracking and sinking of the pavement do not occur, the water permeable bricks are not liable to be trampled, broken and loosened, and when a little ponding is on the ground, and people step on the ponding, the situation that water is squeezed from brick seams to wet and dirty shoes, trousers and the like of people does not occur; and meanwhile construction is fast and convenient, the time and effort are saved, and a great deal of cement stone does not need to be used, so that the construction cost is low, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a permeable road surface. Background technique [0002] At present, when building sidewalks, squares and other public open-air places in cities, in order to solve the problems of water accumulation or poor drainage in rainy days, it is often used to directly lay permeable bricks on ordinary concrete as the permeable pavement of these open-air places. This method is costly and inconvenient for construction. When it rains, the rainwater on the open ground penetrates into the ground through the permeable bricks. However, due to the difference in softness and hardness of the roadbed, after ordinary permeable bricks are laid and used for a period of time, the road surface will sink, the permeable bricks will be broken and loose after being stepped on, and the road surface will be damaged. There will be water quickly squeezed out from the cracks of the bricks, wet and dirty...

AI Technical Summary

Problems solved by technology

However, due to the difference in softness and hardness of the roadbed, after ordinary permeable bricks are laid and used for a period of time, the road surface will sink, the permeable bricks will be broken and loose after being stepped on, and the road surface will be damaged. There will be water quickly squeezed out from the cracks of the bricks, wet and dirty the shoes and trousers of pedestrians, etc.
