Problems solved by technology

[0003] At present, the roof planting technology mainly faces several major technical bottlenecks. One is that planting a matrix layer tens of centimeters thick requires a large amount of planting soil, which is difficult to transport to the roof, and it is easy to increase the load on the roof slab, even if light soil is used. Breaking through the upper limit of the load specified by the code, making most roofs unfeasible
Furthermore, the root system in the covering soil will damage the floor slab, so special technical measures such as root-blocking layer are required, which makes it difficult to control the cost
In addition, maintenance is difficult in summer, hot sun and high temperature require watering every day, but the surface evaporation is far greater than the transpiration of plants, resulting in a great waste of water resources
These have led to the high cost of roof planting and roof gardens and it is difficult to promote them.
[0004] The rainfall has not yet been fully collected and utilized. One rainfall and one row, which also causes a lot of waste of roof water resources

Embodiment 1

[0038] A roof planting method for rainwater utilization and load reduction, water saving, and root control, in which a number of planting units and sidewalks spaced apart from each other are arranged in the roof space according to rectangles, and potted vegetables or potted flower seedlings 1 are arranged in arrays in the planting units, each The bottom of the potted plants is provided with pads to keep a certain gap between the bottom of the potted plants and the ground on the roof, and the rows are parallel to the sidewalk, and the water storage pipes 5 that run through the planting units are arranged between every two rows of potted plants, and are built on the roof to accumulate rainwater. The water storage tank 8 of the well-arranged water storage pipe is arranged perpendicular to the water storage pipe 7 connected to the water storage tank directly above the same end of the water storage pipe, and the drip hole 9 is respectively set on the water delivery pipe and the corre...

Embodiment 2

[0044] A roof planting method for rainwater utilization and load reduction, water saving, and root control, in which a number of planting units and sidewalks spaced apart from each other are arranged in the roof space according to rectangles, and potted vegetables or potted flower seedlings 1 are arranged in arrays in the planting units, each Set pads at the bottom of the potted plants to keep a certain gap between the bottom of the potted plants and the ground on the roof, and make a row parallel to the sidewalk, or arrange pads 6 under each row of potted plants to reserve space for the water storage pipe to pass through and arrange in this row Under the potted plant; Build the reservoir 8 that is used to accumulate rainwater on the roof, arrange the water delivery pipe 7 that is connected with the storage reservoir perpendicular to the storage pipe arrangement directly above the same end of the arranged storage pipe, and on the water delivery pipe and Drip holes 9 and water r...

Abstract

The invention provides a roof planting method with functions of rainwater utilization, load reducing, water saving and root control. Full earthing planting is replaced with a method that potted plantswith special substrates are adopted to manufacture a plurality of one-meter vegetable gardens adjacent to one another at the intervals of roads, and thus the weight is reduced; a pot bottom air isolating technology can further be utilized for automatic root control, so that the problem that a root system damages a floor in full earthing planting is avoided; meanwhile, according to the rainfall intensity, the method that the three modes of roof sponge bricks, rainwater collecting membranes and external wall rainwater collecting pipes are combined is adopted for rainwater collecting and utilization; and meanwhile the drop irrigation and root irrigation technology is combined for water saving. Rainwater reasonable utilization in roof planting can be achieved to save water resources, and meanwhile the problems that during roof planting, full earthing exceeds the floor load, and during earthing planting, the root system damages the floor are avoided.

Description

technical field [0001] The invention belongs to the technical field of roof planting of ecological buildings and sponge city municipal industries, and in particular relates to a roof planting method for rainwater utilization, load reduction, water saving and root control. Background technique [0002] Roof planting can not only cool down and insulate the environment, beautify the environment, purify the air, and improve the local microclimate, but also enrich the city's pitched landscape, compensate for the urban green area occupied by buildings, and greatly increase the city's green coverage. It is a roof form worthy of vigorous promotion. The fourth-generation architecture that is gradually emerging requires the vigorous development of roof and three-dimensional space planting technologies. The state has also specially formulated relevant industry incentive policies and technical regulations and specifications. [0003] Roof planting technology currently faces several maj...
