Water-permeable pavement and construction method thereof

Abstract

The invention discloses a water-permeable pavement which comprises the following components: 100 parts of cement, 100 parts of gypsum powder, 830-950 parts of an aggregate, 0.1-0.3 part of a water reduction agent, 5-8 parts of rubber granules, 4-5 parts of a modified epoxy resin, 2-2.5 parts of a water permeation agent and 0.3-0.5 part of polypropylene fiber. The construction method of the water-permeable pavement comprises the following steps: excavating a road, laying graded broken stone, mixing materials, performing casting, and the like. Broken stone of different granularities is adopted as aggregates, so that both good water permeability and internal structure stability after molding can be ensured; as the cement and the gypsum powder are adopted as gels, the aggregates can be bonded,and meanwhile, the strength of the pavement can be ensured; as the softness of the pavement is improved by using the runner granules, and the aperture of a pavement material is increased by using thewater permeation agent, the water permeation effect can be improved, the toughness of the pavement can be improved through modified epoxy resin and polypropylene fiber, and pavement cracking can be avoided.

Description

technical field [0001] The invention belongs to the technical field of civil construction materials, and relates to a formula of a water-permeable pavement material, in particular to a water-permeable sidewalk and a construction method thereof. Background technique [0002] With the acceleration of urbanization, cities are gradually covered by reinforced concrete structures, which has created new problems. On the one hand, the original groundwater resources under the cities covered by reinforced concrete are constantly being consumed, but the , leading to the infiltration of rainwater, groundwater resources cannot be replenished in time, and gradually dry up, forming underground cavities, which makes the city have the risk of partial subsidence; on the other hand, in the existing urban planning, the rainwater storage and discharge capacity is often limited Insufficient estimation. During the rainy season, due to the insufficient drainage capacity of sewers, the road area is ...

Problems solved by technology

[0002] With the acceleration of urbanization, cities are gradually covered by reinforced concrete structures, which has created new problems. On the one hand, the original groundwater resources under the cities covered by reinforced concrete are constantly being consumed, but the , leading to the infiltration of rainwater, groundwater resources cannot be replenished in time, and gradually dry up, forming underground cavities, which makes the city have the risk of partial subsidence; on the other hand, in the existing urban planning, the rainwater storage and discharge capacity is often limited Insufficient estimation. In the rainy season, due to insufficient sewer drainage and sewage discharge capacity, the road area is seriously flooded, and urban waterlogging occurs in severe cases, which brings great difficulties to urban environmental management.
