Problems solved by technology

[0003] 1) Roof greening needs to consider the load-bearing capacity of the roof of the building: when plants are planted on the roof of the building, the weight of the structural layer and vegetation must be within the allowable load of the building, otherwise, the building may crack and cause the roof to leak. In severe cases, it may also cause a collapse accident.
[0004] 2) Roof greening needs to consider rapid drainage: the building structure layer is an impermeable layer, and rainwater and green sprinkler water must be discharged as soon as possible. If the roof accumulates water for a long time, it will cause the roots of the plants to rot and wither, and it may cause the roof to leak
[0005] 3) Roof greening needs to protect the building roof and waterproof layer: plant roots have a strong penetrating ability. If we do not try to prevent plant roots from damaging the building roof and waterproof layer, it may cause damage to the waterproof layer and affect its service life. possible roof leaks
[0006] 4) Difficulty in daily maintenance in the later stage of roof greening: affected by terrain and architectural design, the maintenance cost of roof greening in the later stage is relatively high
[0007] 5) The roof planting environment is relatively harsh: the roof is exposed to sun, wind and other factors, and the water evaporates too quickly
[0008] 6) Construction period control problem: roof greening construction is difficult and the cycle is long
[0009] At present, it is difficult to have a technology in China to solve all the above problems, so there are various construction technologies, some consider load-bearing but it is difficult to ensure long-term growth of plants, some consider plant growth but have problems with load-bearing and waterproof

Embodiment 1

[0038] Lawn planting test, the specific method is as follows:

[0039] (1) Lay plastic drainage and water storage modules on the concrete surface, the thickness of the plastic modules is 2cm, the length is 42.5cm, and the square structure module with a width of 42.5cm;

[0040] (2) Lay a glass pumice layer on the plastic module, the thickness of the glass pumice layer is 2cm, and the particle diameter of the glass pumice is 0.5-1cm;

[0041] (3) Laying the thickness of the regenerated root matrix layer is 1cm (thermoplastic cotton felt), and the regenerated root matrix layer is made up of the following raw materials in weight percentage: polypropylene staple fiber 30%, cotton 40%, aramid fiber 30%;

[0042] (4) Spread slow-release fertilizer evenly;

[0043] (5) Lay the lawn.

[0044] The plastic module and glass pumice are the main components of the drainage and storage layer. The glass pumice is laid in the plastic module and tightly combined, which can not only quickly re...

Embodiment 2

[0048] A modular vegetation for roof greening, the greening lawn is composed of multiple modular lawns, and the structure of each modular lawn is as follows figure 1 Shown, comprise lawn 1, planting soil layer 2, regenerated root matrix layer 3 and plastic module 4 successively from top to bottom, plastic module 4 comprises plastic basket and the glass pumice layer 41 that is laid in plastic basket inside, the bottom plate of plastic basket 42 is provided with evenly arranged frustum-shaped projections 43 and inverted frustum-shaped grooves 44 , the bottom of the grooves 44 is closed, and the top of the projections 43 is provided with a drainage hole 45 .

[0049] Groove 44 is set so that the plastic basket has a larger water storage capacity to ensure that the lawn has sufficient water source; protrusion 43 is set, and drainage hole 45 is provided at the top of protrusion 43, which can effectively discharge excess water and avoid The root system of the lawn is soaked in water...

Embodiment 3

[0061] Adopt the modular plant of the same structure as embodiment 2, the difference is:

[0062] (1) The particle diameter of the slow-release fertilizer is 1.5mm;

[0063] (2) The composition of the regenerated root matrix layer is: polypropylene fiber 20%, cotton 30%, aramid fiber 50%;

[0064] (3) the thickness of glass pumice layer is 1.5cm, and the particle diameter of glass pumice is 0.5cm;

[0065] (4) The depth of the bottom plate of the plastic basket is 3cm;

[0066] (5) The depth of the groove from the bottom plate is 1cm;

[0067] (6) The plants used in this embodiment are shrubs.

[0068] After about two months, the shrub, rooting substrate layer, and glass pumice layer are tightly combined, fully modular, and the shrub is growing well.

Abstract

The invention relates to modular vegetation used for roof greening. The modular vegetation is composed of a plurality of vegetation sub-modules, and each vegetation sub-module comprises a plant layer,a planting soil layer, a regenerated root substrate layer and a plastic module from the top to the bottom; and each plastic module comprises a plastic basket and a glass pumice layer spread in the plastic basket, the bottom of each plastic basket is provided with uniformly-arranged bulges and a groove, the bottom of each groove is closed, and the top of each bulge is provided with a water discharging hole. Compared with the prior art, the vegetation provided by the invention has the characteristics of modularity and is convenient for construction, a lawn of the vegetation has a light load andgood water storing and discharging capacity, nutrients required for plants are guaranteed, and therefore the vegetation has good market prospects.

Description

technical field [0001] The invention relates to the technical field of roof greening, in particular to a modular vegetation used for roof greening. Background technique [0002] Roof greening is different from general greening on the ground, and has certain particularities. Green roofs need to consider the following aspects at the same time: [0003] 1) Roof greening needs to consider the load-bearing capacity of the roof of the building: when plants are planted on the roof of the building, the weight of the structural layer and vegetation must be within the allowable load of the building, otherwise, the building may crack and cause the roof to leak. Severe cases may also cause collapse accidents. [0004] 2) Roof greening needs to consider rapid drainage: the building structure layer is an impermeable layer, and rainwater and green sprinklers must be drained as soon as possible. If the roof accumulates water for a long time, it will cause rotten roots of the plants to wit...
