Waterlogging-proof ecological pavement for landscaping and preparation method thereof

Abstract

The invention discloses an anti-ponding ecological rod surface for landscaping and a preparation method. The ecological rod surface is formed by pressing after mixing binder, reinforced fibers, coarseaggregate materials with larger internal bore diameter and fine aggregate materials with small internal bore diameter, and the coarse aggregate materials with the larger internal bore diameter and the fine aggregate materials with the small internal bore diameter are made of solid waste such as steel slag, ferrochrome slag and coal gangue after surface hydrophobic treatment. The ecological rod surface specifically comprises a base body layer, a permeable layer and a mortar layer, the base body layer comprises, by weight, 45-55 parts of composite binders, 120-180 parts of solid waste coarse aggregate, 100-120 parts of solid waste fine aggregate, 10-20 parts of addition agents, and 15-25 parts of water; the permeable layer comprises, by weight, 40-45 parts of the binder, 120-180 parts of the solid waste coarse aggregate, 80-120 parts of the reinforced fibers, 5-8 parts of the addition agents and 8-10 parts of the water; the coarse aggregate is formed by crushing multi-hole slag with thick internal bore diameter which is formed by water quenching high-temperature slag, and the fine aggregate is formed by burning fine powders formed by grinding dense slag with small internal bore diameter and the dense slag is formed by natural cooling the high-temperature slag. According to the anti-ponding ecological rod surface for the landscaping and the preparation method, solid waste is usedfor manufacturing seepage materials, and the anti-ponding ecological rod surface for the landscaping can be widely used in permeable layers of road surfaces.

Description

technical field [0001] The invention relates to the field of landscaping, in particular to a water-logging-proof ecological pavement for landscaping and a preparation method thereof. Background technique [0002] At present, the places where urban residents live are mainly surrounded by urban squares, commercial streets, sidewalks, community activity places, parking lots, etc., which are paved with impermeable materials such as granite, marble, glazed tiles, cement and asphalt. The urban environment is very harmful. When it rains, the hardened ground completely prevents rainwater from penetrating directly into the ground, and the accumulated water makes people's travel very inconvenient. When it does not rain, the hardened ground is extremely dry and easy to accumulate dust. , causing dust to fly everywhere, it is difficult to exchange heat and moisture between the ground and the air, and the ability to adjust the temperature and humidity of the urban surface is also reduced...

Problems solved by technology

[0002] At present, the places where urban residents live are mainly surrounded by urban squares, commercial streets, sidewalks, community activity places, parking lots, etc., which are paved with impermeable materials such as granite, marble, glazed tiles, cement and asphalt. The urban environment is very harmful. When it rains, the hardened ground completely prevents rainwater from penetrating directly into the ground, and the accumulated water makes people's travel very inconvenient. When it does not rain, the hardened ground is extremely dry and easy to accumulate dust. , causing dust to fly everywhere, it is difficult to exchange heat and moisture between the ground and the air, and the ability to adjust the temperature and humidity of the urban surface is also reduced. The heat island effect of the city is reduced, and the environmental comfort of the city is greatly reduced.

[0003] At present, some permeable materials such as permeable bricks and permeable pavements in the field of building materials on the market are mainly composed of large-grained skeletons and cement, or artificially processed sand and polymer binders. The problem is that the permeable rate of cement permeable bricks is not high. Or the compressive strength is insufficient, and it is difficult to balance the performance of these two aspects. At the same time, the exploitation of raw materials causes damage to the environment; About 180Kg of steel slag will be discharged, and the discharge of ferrochrome slag is increasing at a rate of more than 400,000 tons per year. If not comprehensively utilized, these solid wastes will silt up rivers, fill waterways, occupy land, pollute water sources and air, causing Environmental hazards; in view of the porous structure of these solid wastes, but also a certain strength, solid wastes can be used to make permeable materials, which can not only reduce the discharge of solid wastes, but also utilize resources to achieve a win-win goal
