Abstract

The invention belongs to the technical field of water permeable brick construction material, and particularly relates to a double-layer structural elastic water permeable brick and a preparation method thereof. The double-layer structural elastic water permeable brick comprises a water permeable base layer and an elastic water permeable surface layer covering the water permeable base layer. The elastic water permeable surface layer is prepared from elastic rubber particles and binder, and the water permeable base layer comprises skeleton particles and a cementing material. The double-layer structural elastic water permeable brick provided by the invention is good in water permeability and pressure resistant strength, good in elasticity, and capable of solving the problem that the surface of the traditional water permeable brick is excessively rigid. Since the surface of the water permeable brick has elasticity, the water permeable brick can be used for paving a racing track, a playing field, a kindergarten pavement and the like; and as the brick is laid one by one, the brick can be entirely replaced, the laid pavement can be locally maintenance, the replacement speed is high, and the repairing is convenient.

Description

technical field [0001] The invention belongs to the technical field of permeable brick building materials, and in particular relates to a double-layer structure elastic permeable brick and a preparation method thereof. Background technique [0002] At present, the floors of city squares, commercial streets, sidewalks, community activity sites, parking lots, etc. are mainly paved with impermeable materials such as granite, marble, glazed tiles, cement and asphalt. The impermeable floors are very harmful to the urban environment. When it rains, the impermeable ground completely prevents the rainwater from infiltrating directly into the ground, and the accumulated water makes it very inconvenient for people to travel; the precious water resources eventually flow away with the drainage pipes, which increases the burden on urban drainage facilities; The large loss of rainwater makes it difficult for the groundwater level to rise, which directly affects the health of urban vegetat...
