Abstract

The invention relates to a roof ecological planting system and a construction method thereof. An insulating layer, a waterproof anti-root piercing layer, a cement mortar protective layer, a drainage layer, a filtering layer, a plant substrate layer and a roof utilization layer are arranged on a base structure layer sequentially, wherein the waterproof anti-root piercing layer adopts an anti-plantroot piercing waterproof coating; the drainage layer adopts plastic anti-drainage plates; and joints between the plastic anti-drainage plates and the periphery of a pipeline are bonded by an anti-plant root piercing adhesive. The entire system has the advantages of reducing construction processes, shortening construction period and lowering construction cost, along with excellent material performance and clear function of each layer. Three anti-plant root piercing protection lines consist of the anti-plant root piercing waterproof coating, a drainage plate, a cement mortar protective layer and the anti-plant root piercing adhesive, so that the system can adapt to normal growth of various plants and the waterproof function of a roof for long-term use is guaranteed.

Description

technical field

[0001] The invention relates to a roof ecological planting system, in particular to a roof planting system with multiple functions such as heat preservation, waterproofing and drainage, anti-plant root puncture, filtration, planting substrate and surface utilization, and a construction method thereof. Background technique

[0002] At present, with the large-scale development and utilization of large and medium-sized cities and towns in my country, the living space and green area for maintaining human survival are getting smaller and smaller, and the ecological environment of the city is deteriorating day by day, which has a great impact on people's normal work and life. . However, with the continuous improvement of living standards, people have put forward higher requirements for the working and living environment. For this reason, it is of great significance to utilize and develop the green planting of urban roof space, such as:

Examples

Embodiment 1

[0112] according to figure 1 Shown in the structure, the construction method of a kind of roof ecological planting system of the present invention is carried out according to the following steps:

[0113]First, clean up the floating soil, sand, and oil on the base of the roof, and spray high-strength polyurethane foam on the base with a thickness of 40mm; after cooling, spray, roll or brush the anti-plant root puncture waterproof coating for 3 to 4 times, the first After drying for one time, brush the second time. The thickness of the dried film is 2mm; after the film is completely dried and cured for 3 to 7 days, a 20mm thick cement mortar protective layer is covered on the film. The ratio is 1:2.5; after the cement mortar protective layer is cured for 7 to 14 days, a layer of polyolefin plastic waterproof and drainage board is laid, and the joints between the waterproof and drainage boards and the periphery of the pipe are glued and connected with anti-plant root puncture ad...

Embodiment 2

[0115] refer to figure 1 Shown in the structure, the construction method of a kind of roof ecological planting system of the present invention is carried out according to the following steps:

[0116] Thoroughly clean up floating soil, gravel, and oil stains on the roof base, and spray high-strength rigid polyurethane foam on the base, with a thickness of 50mm; after cooling, spray, roll or brush the anti-plant root puncture waterproof coating 4 times, every After spraying, rolling or brushing the anti-plant root puncture waterproof coating once, cover a layer of non-woven fabric, laying two layers of non-woven fabric in total, spraying, rolling or brushing the anti-plant root puncture waterproof coating two times on the second layer of non-woven fabric After the first coat of paint dries, paint the second coat. The total is two coats and four coats. The thickness of the film after drying is ≥ 2mm; after the film is completely dry and maintained for 3-7 days, cover the film wi...

Embodiment 3

[0118] according to figure 1 Shown in the structure, the construction method of a kind of roof ecological planting system of the present invention is carried out according to the following steps:

[0119] First clean up the floating soil, sandstone, oil stains, etc. on the roof base, and then add the inorganic particle mortar and mix it evenly with water and spread it on the base layer. The thickness is 60mm. The ratio of perlite: cement: rubber powder of the inorganic particle mortar is 1:2:0.1; After the inorganic particle mortar is cured, spray, roll or brush the anti-plant root puncture waterproof coating for 4 times, and cover a layer of non-woven fabric after spraying, rolling or brushing the anti-plant root puncture waterproof coating once , a total of two layers of non-woven fabric are laid, and the top of the second layer of non-woven fabric is sprayed, rolled or brushed with anti-plant root puncture waterproof coating for two times, and the first coating is dried and...
