Imitation steel fiber recycled aggregate pervious concrete pavement structure

Abstract

The invention discloses an imitation steel fiber recycled aggregate pervious concrete pavement structure which comprises a plain concrete layer arranged on a plain soil tamping layer; the water storage layer comprises a pebble layer and a recycled coarse aggregate layer which are laid on the plain concrete layer; the permeable layer is arranged above the water storage layer and is composed of steel-fiber-imitating recycled aggregate permeable concrete, and the steel-fiber-imitating recycled aggregate permeable concrete comprises recycled coarse aggregate and pebbles; the filtering surface layer is laid on the upper surface of the permeable layer; the fixed metal net rack is arranged on the outer side of the pavement structure and wraps all the layers; the water storage tank is arranged on one side of the pavement structure layer. Rainwater recycling is achieved through the water storage layer and the water storage tank, the efficient water permeability of the whole road surface is guaranteed, the situation that water accumulated on the ground affects walking is avoided, and therefore the situation that an existing permeable road only enables rainwater to permeate into a foundation, and no recycling measure is taken is effectively avoided; and the recycled aggregate is used as a pavement structure layer, so that the sustainable development of the building industry is effectively promoted.

Description

technical field [0001] The invention relates to the technical field of pavement structure design, in particular to a permeable concrete pavement structure imitating steel fiber recycled aggregate. Background technique [0002] With the acceleration of the pace of urbanization in my country and the implementation of large-scale surface hardening of urban construction land, cities are full of impermeable buildings such as cement floors and asphalt roads. With the expansion of the impermeable pavement area, the shrinkage of the urban green area and the compaction of the soil and rock layers, the seepage water function of the urban ground is almost lost. [0003] With the continuous expansion of my country's urban scale and accelerated development of engineering construction, a huge amount of construction waste has been generated, of which waste concrete accounts for 41%. There are many adverse effects of waste concrete: land occupation, serious impact on soil quality, water an...
