Water-permeable pavement and pavement method thereof

Abstract

The invention provides a permeable pavement and a laying method thereof. The permeable pavement comprises: a paving element, a filter layer, a first permeable concrete base, a second permeable concrete base and a crushed stone layer, and the crushed stone layer is laid on a consolidated foundation On the upper surface, a water collector is arranged in the gravel layer, and the water collector is connected to a drainage pipe. The first permeable concrete base is laid on the upper surface of the gravel layer, and the first permeable concrete base The upper surface of the second permeable concrete base is laid with a glass fiber geogrid, the upper surface of the second permeable concrete base is laid with the filter layer, and the upper surface of the filter layer is The paving elements are laid on the surface, and the paving elements are provided with gaps, wherein, the side and the bottom surface of the permeable pavement are both provided with impermeable membranes. The permeable pavement prepared by the invention has the advantages of strong bearing capacity, good durability and good water permeability.

Description

technical field [0001] The invention relates to the laying of a permeable pavement, in particular to a permeable pavement and a laying method thereof. Background technique [0002] With the popularization of permeable pavement related knowledge and the replacement of the entire road paving technology level, more and more cities have begun to use permeable pavement as the preferred paving material for urban roads and public areas. However, permeable pavement also has deficiencies and shortcomings. The first problem of permeable pavement is its low strength. Thanks to the large porosity of permeable concrete, permeable pavement has a good drainage effect, but at the same time it also reduces the strength of permeable pavement. Case. A large void ratio reduces the contact area between the aggregate and the aggregate, which leads to a decrease in the strength of the material. The large void ratio also increases the contact area of ​​the binder with air and sunlight. Therefore, ...

Problems solved by technology

However, permeable pavement also has deficiencies and shortcomings. The first problem of permeable pavement is its low strength. Thanks to the large porosity of permeable concrete, permeable pavement has a good drainage effect, but at the same time it also reduces the strength of permeable pavement. Case

A large void ratio reduces the contact area between the aggregate and the aggregate, which leads to a decrease in the strength of the material. The large void ratio also increases the contact area of ​​the binder with air and sunlight. Therefore, the aging of the binder over time The speed is faster than the general densely graded materials, the durability is relatively low, and the service life is short
