Light roof greening method

Abstract

The invention relates to a light roof greening method, and belongs to the field of roof greening technologies. The light roof greening method includes steps of (1), laying waterproof root blocking layers on the surfaces of roofs; (2), laying glass and pumice layers on the surfaces of the waterproof root blocking layers; (3), laying and fixing first regeneration rooting substrate layers; (4), uniformly broadcasting slow-release fertilizers; (5), laying and fixing second regeneration rooting substrate layers; (6), mounting and fixing sprinkling irrigation systems; (7), laying planting substrates on the second regeneration rooting substrate layers; (8), planting plants on the planting substrates. Compared with the prior art, the light roof greening method has the advantages of light load, high water holding and drainage capacity, short construction period, easiness in maintenance and the like.

Description

technical field [0001] The invention relates to a roof greening method, in particular to a light roof greening method. 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 planting layer must be within the allowable load of the building, otherwise, the building may crack and cause the roof to leak, which is serious 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 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 wither, and may cause roof leakage in sev...

AI Technical Summary

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 planting layer must be within the allowable load of the building, otherwise, the building may crack and cause the roof to leak, which is serious 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
