Description

green roof planting block

technical field

The utility model relates to a building material, in particular to a porous roof greening planting block used in the roof greening planting layer. the

technical background

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 fertilizers, water-retaining agents, etc. (such as the invention of "a roof greening base material and its preparation method", patent number: 200610019301.4); d, using solid waste As the main component, add technical solutions such as long-acting fertilizers, such as ("roof greening system and greening method", application number: 200910063086.1). These technical solutions generally consider the nutritional needs of plant growth, soil three-phase ratio, drought resistance requirements, light weight requirements, etc. in the formula design. During their construction, the on-site or pre-mixed granular substrate mixture is generally spread according to the designed thickness of the planting layer, and then plants are planted on it. This construction method has a great impact on the construction site; it is difficult for green plants to achieve high coverage in a short period of time; while the technology of "pumping lightweight roof greening substrate" (application number: 200710053781.0) has little impact on the construction site , the production capacity is very large, but because this technology requires the use of more mechanical equipment, it is uneconomical when greening a small area of the roof; and it also has the disadvantage that it is difficult for green plants to obtain high coverage in a short period of time. the

Contents of the invention

The object of the present invention is to provide a porous roof greening planting block used in the roof greening planting layer, which can be produced in a factory, and can be used for rapid greening of the roof in a greenhouse. the

The porous block is a cube or a cuboid or a block whose upper and lower surfaces are regular polygons. the

In order to enhance the early permeability of the planting block, there can be grooves on the side of the planting block. the

In order to enhance the integrity of the planting block, a plastic net can be arranged at the bottom of the planting block. the

The main body of the utility model is a planting block made by mixing single-graded aggregate, clay, cement, organic matter, slow-release fertilizer and water in proportion. Aggregate is the skeleton of the planting block, and clay and cement (referred to as cement soil) are the cementing materials that wrap the aggregate. After the cement is hydrated and hardened, the planting block can be formed. Due to the single gradation of the aggregate and less cementing material, the planting block is shaped like a macroporous concrete structure, and the use of cement can also reduce the soil loss of the planting block. Organic matter, clay and slow-release fertilizers make the planting fast biocompatible and increase the porosity of the planting block after the organic matter decays away. Plants grow on the upper surface of the planting block. the

The aggregate used in the utility model is a single-graded aggregate with a particle size range of 5-40 mm, which is one or more of broken bricks, broken concrete, pebbles, crushed stones, ceramsite, pumice and expanded shale. Proportional composition; the cement used can be ordinary Portland cement or low-alkali cement; the mass ratio of cement to clay is between 5-30%; the organic matter is rotted and deodorized rice husk, leaves, branches, crop straw and sawdust One or several kinds are composed in any proportion, and the particle size is 1-12mm; the slow-release fertilizer is a slow-release compound fertilizer. the

The utility model is suitable for alkali-resistant low succulent plants or herbaceous plants or shrubs. It can be planted by seed and cuttings. the

The beneficial effects of the utility model are reflected in: it has the advantage of being porous, suitable for plant growth and roof drainage, and can realize large-scale factory production, and can quickly realize roof greening by using it; due to the use of cement, the block does not undergo large deformation in the later stage and soil loss, and the construction is simple and cheap, it is an ideal roof green planting layer material. When crushed bricks and crushed concrete are used as aggregates, the recycling of solid waste is realized; when lightweight aggregates such as ceramsite, pumice and expanded shale are used, the weight of planting blocks can also be reduced. the

As shown in Figure 1 and Figure 3, a porous roof greening planting block includes a block 1, which can be a cuboid, a cube, or a block whose upper and lower surfaces are regular polygons, and the block 1 is made of aggregate 3, wrapped bone Material 3 is composed of cement soil 4 containing slow-release fertilizer, organic matter 5 dispersed in cement soil 4 and pores 6 distributed in cement soil 4, and plants 8 grow on block 1. the

Shown in Fig. 2, Fig. 4 is the technical scheme that the present invention has side groove, block body 1 side surface has groove 2, can be that one side has groove, also can be that multiple sides have groove; Groove 2 is trapezoidal Or rectangle or triangle or semicircle. Other legends and structural descriptions in Figures 2 and 4 are the same as above. the

Inside the block 1 a plastic mesh 7 may also be arranged. The plastic mesh 7 is parallel to the lower surface of the block 1, and may be 2-10mm away from the lower surface of the block 1. the

Detailed ways

The aggregate used in the utility model is a single-graded aggregate with a particle size range of 5-40 mm, which is one or more of broken bricks, broken concrete, pebbles, crushed stones, ceramsite, pumice and expanded shale. Proportional composition; the cement used can be ordinary Portland cement or low-alkali cement; the mass ratio of cement to clay is between 5% and 30%; organic matter is rice husk, leaves, branches, crop straw and sawdust. the

One or several kinds are composed in any proportion, obtained after decomposing and deodorizing, and the size is 1-12mm. Slow-release fertilizers are slow-release compound fertilizers. The utility model is suitable for alkali-resistant plants, and low and succulent plants or herbaceous plants or shrubs are selected. the

The production of the utility model can be carried out in factories and greenhouses, and the blocks 1 can be produced in factories by using ordinary brick making machines, and then transferred to greenhouses for breeding and seedling acceleration. the

After the plants 8 grow to a certain coverage rate, the present invention can be used in roof greening. When in use, they can be directly tiled on the filter layer to replace the traditional planting layer granular mixed greening substrate. the

The utility model also can directly use the block body 1 without plants as the final product for users to plant plants themselves. the

When it rains, the excess rainwater infiltrates from the groove 2 on the side of the block 1 and the through pores 6 in the block 1, so as to speed up the drainage of the roof and prevent the plants from being waterlogged. the

The utility model can be used in conjunction with various types of waterproof layers, drainage layers, and filter layers, such as a water-retaining drainage board for roof greening (application number: 200920087199.0), which can improve drought resistance. the

The utility model has the advantages of porosity, can realize large-scale factory production, is suitable for plant growth and is beneficial to roof drainage, and can immediately realize a high coverage rate of roof greening; due to the appropriate amount of cement and cement soil, no large deformation and soil loss will occur later, Moreover, the construction is simple and the price is cheap, so it is an ideal roof greening planting layer material. the
