Concrete cast-in-situ type green plant planting waterproof cushion

Abstract

The invention discloses a concrete cast-in-situ type green plant planting waterproof cushion. The concrete cast-in-situ type green plant planting waterproof cushion comprises a base layer, a waterproof roll layer, an insulation layer, an anti-cracking layer, a drainage layer, a water storage layer, a water filter layer and a planting layer. The waterproof roll layer is arranged at the upper end ofthe base layer. By arranging the water storage layer, water permeates downward. By arranging a groove and sponge, the water storage efficiency can be improved greatly, and water stored in the grooveis unlikely to run off, so that the utilization ratio of a water resource is improved. Meanwhile, the water storage amount is increased for planting, so that a condition that vegetation dies away or dies due to belated water supplement is avoided. Permeating into the drainage layer, water can flow out outward from a drainage channel, so that damage to the structure due to water accumulation in a concrete structure is avoided. By arranging the anti-cracking layer, a concrete pouring layer is connected and fastened to a bump on the surface of a water isolating board to play an anti-cracking role, so that the anti-cracking property of the integral structure is improved, cracks are avoided, and water permeates downward, so that the waterproof performance of the structure is improved.

Description

technical field [0001] The invention relates to the technical field of waterproofing, in particular to a concrete cast-in-place waterproof cushion for planting green plants. Background technique [0002] In order to beautify the environment, reduce noise, reduce dust and heat insulation, some green plants are generally planted on the roof. After the prepared water or rainwater is poured, it will be absorbed by the planting soil, and the water will penetrate downward, which will cause damage to the concrete structure. The traditional waterproof structure, Generally, a waterproof membrane is installed on the surface of the concrete. This kind of waterproof structure is simple and is corroded by the soil, which makes the waterproof effect poor. Moreover, the traditional concrete top planting has poor penetration resistance. It penetrates and grows along the gaps on the surface of the concrete pouring layer, thereby destroying the concrete structure and reducing the waterproof p...

[0002] In order to beautify the environment, reduce noise, reduce dust and heat insulation, some green plants are generally planted on the roof. After the prepared water or rainwater is poured, it will be absorbed by the planting soil, and the water will penetrate downward, which will cause damage to the concrete structure. The traditional waterproof structure, Generally, a waterproof membrane is installed on the surface of the concrete. This kind of waterproof structure is simple and is corroded by the soil, which makes the waterproof effect poor. Moreover, the traditional concrete top planting has poor penetration resistance. It penetrates and grows along the gaps on the surface of the concrete pouring layer, thereby destroying the concrete structure and reducing the waterproof performance. At the same time, the vegetation is directly exposed to light, and the water evaporates quickly. Because the water cannot be absorbed in time, it is easy to cause the vegetation to wither or die. Therefore, the design of a It is necessary to plant a concrete cast-in-place green planting waterproof cushion
