Method for adopting building waste for planting afforesting grass on roof

Abstract

The invention discloses a method for adopting building waste for planting afforesting grass on a roof. The method is based on a roof afforesting grass planting system. The planting system includes a root isolating layer, a particle layer, a root protection layer, a first planting base material layer and a vegetation layer which are arranged from bottom to top in sequence. The root isolating layer,the particle layer and the root protection layer form an air reflux system and a flow guiding layer and create a second rooting space; meanwhile, the building waste is utilized to make planting basematerials and particles on the particle layer, the whole system is smooth in drainage function and great in ventilation effect and moisture preservation effect without depending on any conventional organic planting medium, and by completely utilizing the building waste, roof planting can be achieved; the technical problems are solved that grass overgrows in rainy seasons, is too fine and tender, goes moldy and falls down, drainage is unsmooth, development of roots is hindered, and the moisture preservation performance is poor. Zero management after the grass grows all over a garden is achieved. Moreover, the system is suitable for mixed planting of different kinds of afforesting grass, different afforesting landscapes can be achieved, formation of a roof vegetation ecological system is facilitated, and zero-management and long-term sustainable growth of roof afforesting vegetation are truly achieved. Moreover, the construction is simple, the cost is low, the environment is protected, loads are light, and the structure is stable.

Description

technical field [0001] The invention belongs to the technical field of green planting. More specifically, it relates to a method for planting green grass on the roof by using construction waste. Background technique [0002] The roof occupies a large space in the city. With the continuous expansion of this space, the urban heat island effect is increasing; Shrinkage is obvious, and the waterproof layer is prone to aging and denaturation, resulting in roof leakage. Therefore, green roofs have many benefits: 1. Improve urban green coverage and create aerial landscapes; 2. Absorb dust to reduce noise and improve environmental quality; 3. Reduce urban heat island effect and play ecological functions; 4. Alleviate urban floods and reduce drainage 5. Effectively protect the roof structure and prolong the waterproof life; 6. Keep the building warm in winter and cool in summer, saving energy consumption. The roof environment is harsh, and greening is difficult. The greening rate ...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the defects and deficiencies of the existing roof greening technology and the problem that construction waste is difficult to deal with, and to provide a system with good effect and very simple planting green grass on the roof

Using bricks, concrete blocks, tiles, wood chips, plastering powder, and sand in construction waste to be broken into particles as the granular layer and planting base material greatly reduces costs, is simple and easy, and solves the problem of crazy growth, tenderness, and Mildew, lodging, poor drainage, poor moisturizing effect, hindered root development and other technical problems
