An exposed aggregate ceramsite permeable concrete road structure based on solid waste recycling

Abstract

The invention discloses an exposed aggregate ceramsite permeable concrete road structure based on the reuse of solid waste. Pottery sand filter layer, exposed aggregate fly ash non-fired ceramsite permeable concrete layer and overcoat agent layer, the upper surface of the base layer is laid with a reverse filter layer, and the upper surface of the reverse filter layer is laid with urban construction waste recycled aggregate As a cushion layer, the upper surface of the urban construction waste recycled aggregate cushion layer is laid with a fly ash unburned pottery sand filter layer, and the upper surface of the fly ash unburned pottery sand filter layer is laid with exposed aggregate fly ash free Burning ceramsite permeable concrete layer, the upper surface of the exposed aggregate fly ash-free ceramsite permeable concrete layer is laid with a cover agent layer, which avoids the large use of non-renewable river sand and mountain rock natural resources, which is conducive to the construction of "sponge city" Promote and protect the natural ecological environment.

Description

technical field [0001] The invention belongs to the field of municipal construction and relates to concrete road technology, in particular to an exposed aggregate ceramsite permeable concrete road structure based on solid waste recycling. Background technique [0002] In the construction of "sponge city", exposed aggregate permeable concrete pavement is one of the commonly used methods. The exposed aggregate permeable concrete pavement is a high-grade decorative permeable concrete formed on the basis of permeable concrete technology combined with the "exposed aggregate" process. Colored aggregates are used instead of ordinary stones. Use a high-pressure water gun to wash away the condensed surface cement slurry, so as to realize a new type of permeable pavement with the effect of "exposed aggregate", which can realize pavement permeable, reduce water accumulation and urban waterlogging, reduce heat island effect, and pavement decoration , anti-skid road and other functions....

Problems solved by technology

[0005] However, the exposed aggregate permeable concrete ground structure has the following problems: 1. A large amount of non-renewable river sand, mountain rocks and other natural resources are used for cushioning, cushioning, reinforcement, and coarse sand filter layer, and waste materials such as urban construction waste are not collected. Applying it to the exposed aggregate permeable concrete ground structure is not energy-saving and environmentally friendly, and it also increases the construction cost of the concrete road structure; Poor, the exposed aggregate is easy to fall off during use, thus lacking lasting protection for the exposed aggregate permeable concrete floor, which reduces the aesthetics of the exposed aggregate pervious concrete; 3. The exposed aggregate permeable concrete floor is only made of coarse sand Filtration cannot effectively adsorb and filter the dust and impurities in the water. When the water source infiltrates, it is easy to block the permeable pores, reduce the water permeability, and easily lead to the collapse of the roadbed. Therefore, we propose a solid waste reuse method. Ceramsite permeable concrete road structure with exposed aggregate
