Problems solved by technology

This construction method has a great impact on the construction site; the shortcomings of green plants are difficult to achieve high coverage in a short period of time
However, although the "pumping lightweight roof greening base material" (application number: 200710053781.0) technology has little impact on the construction site and a large production capacity, it is not economical for small-area roof greening because it requires the use of more mechanical equipment. ; And there is also the shortcoming that it is difficult for green plants to obtain high coverage in a short period of time

Abstract

The invention provides a light porous roof greening planting block used on a roof greening planting layer and a manufacturing method thereof. The roof greening planting block consists of aggregates, cement soil, an organic matter, a slow release fertilizer, water and plants. The structure of a planting block structure molded by a brick molding machine or a brickwork molding machine is similar to a porous concrete structure. The manufacturing method comprises the following steps: material preparation, stirring, molding, seeding or sticking and culturing. The product provided by the invention has the advantages of light weight and multihole and can realize large-scale industrial production. The light porous roof greening planting block can quickly green a roof, is simple in construction and low in price, and is an ideal roof greening planting layer material. The method provided by the invention can be easily implemented by the traditional mechanical equipment.

Description

technical field [0001] The invention relates to a building material, in particular to a lightweight and porous roof greening planting block used in a roof greening planting layer and a manufacturing method thereof. technical background [0002] The structure of a green roof is generally a structural layer, a waterproof layer, a drainage layer, a filter layer, a planting layer and vegetation on it. The disclosed invention and other technical data provide the technical schemes of several types of roof greening substrates or planting layers: a, take the soilless light mineral material as the main component, and add fertilizers, water-retaining agents, etc. (such as the technical scheme of the invention "Inorganic cultivation substrate for greening", application number: 200410072723.9); b, the technical scheme of using farmland or farmland topsoil as the main component, adding fertilizers, etc. 96100525.4); c, using organic matter as the main component, adding long-acting ferti...
