Embodiment 1

[0029] S1 Add 65 parts of aggregate, 20 parts of inorganic cementitious material, 0.5 part of permeable concrete reinforcing agent and 8 parts of water into the mixer for stirring. After stirring evenly, add 1 part of inorganic modified polymer resin and continue stirring until form a homogeneous mixture;

[0030] S2 Transport the evenly stirred mixture to the construction site. The bottom layer of permeable concrete is vibrated and leveled, and the surface layer is polished and smoothed with a cement trowel. After the construction is completed, it is covered and maintained;

[0031] After S3 curing for 7 days, remove the cover and other debris on the surface of the permeable concrete, and then spray the photocatalytic permeable concrete protective agent. The material consumption is 0.3kg / ㎡, and it can be used normally 24 hours after construction.

Embodiment 2

[0033] S1 Add 70 parts of aggregate, 18 parts of inorganic cementitious material, 1.0 part of permeable concrete reinforcing agent and 6 parts of water into the mixer for stirring. After stirring evenly, add 0.5 parts of inorganic modified polymer resin and continue stirring until form a homogeneous mixture;

[0034] S2 Transport the evenly stirred mixture to the construction site. The bottom layer of permeable concrete is vibrated and leveled, and the surface layer is polished and smoothed with a cement trowel. After the construction is completed, it is covered and maintained;

[0035] After 7 days of S3 curing, remove the covering and other debris on the surface of the permeable concrete, and then spray the photocatalytic permeable concrete protective agent. The material consumption is 0.25kg / ㎡, and it can be used normally 24 hours after construction.

Embodiment 3

[0037] S1 Add 75 parts of aggregate, 18 parts of inorganic cementitious material, 0.5 part of permeable concrete reinforcing agent and 7 parts of water into the mixer for stirring. After stirring evenly, add 0.5 part of inorganic modified polymer resin and continue stirring until form a homogeneous mixture;

[0038] S2 Transport the evenly stirred mixture to the construction site. The bottom layer of permeable concrete is vibrated and leveled, and the surface layer is polished and smoothed with a cement trowel. After the construction is completed, it is covered and maintained;

[0039] After S3 curing for 7 days, remove the cover and other debris on the surface of the permeable concrete, and then spray the photocatalytic permeable concrete protective agent. The material consumption is 0.20kg / ㎡, and it can be used normally 24 hours after construction.

Abstract

The invention relates to the technical field of concrete roads, and discloses a pervious concrete road for purifying automobile exhaust and a construction method of the pervious concrete road. The pervious concrete road comprises the following components of, in parts by mass, 60-75 parts of aggregate, 18-20 parts of inorganic cementing material, 0.5-1 part of pervious concrete reinforcing agent, 0.5-1 part of inorganic modified polymer resin, 6-8 parts of water and 0.15-0.3 kg / m<2> of photocatalytic pervious concrete protective agent. According to the pervious concrete road for purifying the automobile exhaust and the construction method of the pervious concrete road, by means of the pervious concrete reinforcing agent, the inorganic modified polymer resin and the photocatalysis pervious concrete protective agent, on the basis that good water permeability, abrasion resistance and pressure resistance of pervious concrete are achieved, the automobile exhaust can be well purified, environmental pollution is reduced, and the problem that an existing pervious pavement is poor in purification effect is solved.

Description

technical field [0001] The invention relates to the technical field of concrete roads, in particular to a permeable concrete road for purifying automobile exhaust and a construction method thereof. Background technique [0002] Automobile exhaust is the exhaust gas produced by the use of automobiles. It contains hundreds of different compounds. The pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. Automobile exhaust pollution is environmental pollution caused by exhaust gas emitted by automobiles. [0003] In addition, carbon dioxide (CO2) emitted by vehicles 2 ), sulfide SO 2 , Nitrogen oxide NO x (NO and NO 2 ), chlorofluorocarbons, etc. make the atmospheric environmental problems such as greenhouse effect, ozone layer destruction and acid rain more serious; CO, NO emitted by automobiles x , SO x , unburned hydrocarbons HC, particulate matter PM and odorous gases pollute the air, whic...
