Paving system of plastic grid sand-based water permeable bricks

Abstract

The invention relates to a paving system of plastic grid sand-based water permeable bricks. The paving system comprises a soil base layer, a graded broken stone layer and a water permeable surface layer from bottom to top, wherein the water permeable surface layer comprises plastic grids, a broken pebble layer and sand-based water permeable bricks; support strips are arranged in the plastic grids; the broken pebble layer is arranged in the plastic grids in a paving manner and located under the support strips; the sand-based water permeable bricks are placed under the support strips and are parallel and level to the top surfaces of the plastic grids. The paving system of the plastic grid sand-based water permeable bricks is relatively high in strength, increases the infiltration speed of rain water, is free from a leveling blanket, is high in construction speed, and realizes the modular construction; the surface layer is extremely smooth and attractive after being paved; reprocessed plastic is used, so energy and materials are saved, and the environment is friendly and ecological.

Description

【Technical field】 [0001] The invention relates to a permeable pavement system, in particular to a plastic grid sand-based permeable brick pavement system, which combines the use of sand-based permeable bricks with the use of plastic grids, and can be used for sidewalks, parking lots, squares , landscape hardening area, etc., which belong to the field of construction engineering technology. 【Background technique】 [0002] With the development of the city, the impermeable area of ​​the city is getting larger and larger, the infiltration of rainwater accounts for less and less of the total rainfall, and there are more and more urban waterlogging phenomena. Pollutants flow into rivers, and the road surface water problem becomes more serious. In this case, permeable pavement came into being. As an ecological infrastructure, permeable pavement can increase the rainfall infiltration rate from 10% of the hardened site to more than 75%, which can not only greatly reduce the surface...

AI Technical Summary

Problems solved by technology

Because the strength of the plastic grid is not high, it is generally used in parking lots with low requirements. In addition, the plastic grid is not very smooth after being filled with sand and gravel, so it is generally not used for sidewalks and bicycle lanes

[0004] There are many problems in the traditional permeable bricks or permeable grids used for sidewalks, landscape roads, parking lots and squares, such as long construction time, difficult leveling layer construction, repeated work when placing permeable bricks, and difficult surface layer. Low seepage efficiency, etc.
