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, load reduction, water saving and root control, wherein a plurality of planting units and sidewalks distributed at intervals are arranged in a rectangular space on the roof space, and potted vegetables or potted flower seedlings 1 are arranged in an array in the planting units. A spacer is set at the bottom of the potted plant so that a certain gap is maintained between the bottom of the potted plant and the ground on the roof. With the direction parallel to the sidewalk as a row, a water storage pipe 5 that runs through the planting unit is arranged between every two rows of potted plants, and is built on the roof to store rainwater. The water storage tank 8 is arranged vertically above the same end of the water storage pipe, and the water delivery pipe 7 communicated with the water storage tank is arranged perpendicular to the water storage pipe, and a drip hole 9 is opened respectively on the water delivery pipe and the ...

Embodiment 2

[0044] A roof planting method for rainwater utilization, load reduction, water saving and root control, wherein a plurality of planting units and sidewalks distributed at intervals are arranged in a rectangular space on the roof space, and potted vegetables or potted flower seedlings 1 are arranged in an array in the planting units. A spacer is arranged at the bottom of the potted plant so that a certain gap is maintained between the bottom of the potted plant and the ground on the roof, and the row is parallel to the sidewalk, or a spacer 6 is arranged under each row of potted plants to reserve space for the water storage pipe to pass through and arrange in the row. Under the potted plant; build a water storage tank 8 on the roof for storing rainwater, arrange a water delivery pipe 7 connected to the water storage tank perpendicular to the same end of the arranged water storage pipe, and connect the Drip holes 9 and water receiving holes are respectively provided at the corres...

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 particularly relates to a roof planting method for rainwater utilization, load reduction and water saving and root control. Background technique [0002] Roof planting can not only cool and insulate, beautify the environment, purify the air, and improve the local microclimate, but also enrich the pitching landscape of the city, compensate the urban green area occupied by buildings, and greatly improve the green coverage of the city. A roofing form worthy of vigorous promotion. The fourth generation of buildings that are gradually emerging requires vigorous development of roof and three-dimensional space planting technology, and the state has specially formulated relevant industry incentive policies and technical regulations and specifications. [0003] Roof planting technology is currently faced with several major technical b...
