An environmentally friendly decorative permeable pavement structure and its construction method

Abstract

The invention relates to an environment-friendly decorating water permeable pavement structure and a construction method thereof. The structure comprises water permeable pavement slabs, wherein a plurality of water permeable holes are formed in the water permeable pavement slabs; channels for enabling adjacent water permeable pavement slabs to be connected and accommodating concrete are formed in the peripheral sides of the water permeable pavement slabs; concrete bonding layers are paved at the lower parts of the water permeable pavement slabs, and macadam water storage layers are arranged at the lower parts of the concrete bonding layers. The construction method comprises the following steps: levelling a base layer; placing the macadam water storage layers on the base layer in a filling manner; paving the concrete bonding layers at the upper parts of the macadam water storage layers, and paving the prefabricated water permeable pavement slabs on the concrete bonding layers at the same time, wherein a certain clearance is reserved between every two water permeable pavement slabs; carrying out the borehole cleaning by taking the water permeable holes of the water permeable pavement slabs as basic holes before the initial set of the concrete bonding layers, so as to enable the water permeable holes to penetrate the concrete bonding layers and extend to the macadam water storage layers; after the final set of the concrete bonding layers, pouring fine stone concrete into the clearances between adjacent water permeable pavement slabs to fill up the channels, and carrying out pointing processing. According to the invention, through the adoption of the environment-friendly decorating water permeable pavement structure and the construction method thereof, the water permeability of the water permeable pavement can be improved, underground water sources can be conserved, and local ecological environment can be improved.

Description

technical field [0001] The invention relates to an environment-friendly decorative permeable pavement structure and a construction method thereof. Background technique [0002] Permeable pavement is suitable for sidewalks, parking lots, parks, lightweight lanes and various stadium roads. In the past, there was no uniform standard for permeable pavement engineering, and the pavement was not permeable and air-permeable. Among them, the surface of permeable concrete was rough and the bearing capacity was low; Bricks rely on capillary pores to permeate water, and they are easy to block for a long time. If they are paved with cement sand or fine stone concrete, they are impermeable, have poor bearing capacity, and are expensive; laying plastic pipes to make permeable holes is costly and time-consuming. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly decorative permeable pavement structure and its construction method, ...
