Description

Controllable water supply roof planting system

Technical Field

The utility model belongs to building and afforestation field, concretely relates to roof planting system of controllable formula water supply.

Background

The roof, called "fifth facade of building", has been a still to be reclaimed "virgin land" in the urban area, in a position to be ignored, forgotten or even spoiled. On one hand, urban greening area and water surface area are eaten by more and more high-density buildings, on the other hand, a large number of roofs still face the sky and are not effectively utilized, or even become a garbage warehouse, which is a dead angle in the current urban construction and management. The roof greening promoted by a plurality of ecological environment experts, city planning experts and building design experts can not only give consideration to building landscape, but also improve the urban ecological environment, but in the existing roof greening and landscaping construction, the irrigation of roof plants is a difficult point, and the problems that the roof needs to be well waterproofed in rainy season, the water accumulation of the roof is prevented, the plant root system damages the waterproof layer to cause water leakage, the roof plants are drowned and the like are solved; in continuous dry weather, the root system of the roof plant needs to be continuously and sufficiently supplied with water, and the spraying system usually used on the ground is not energy-saving and is not convenient to use on the roof.

SUMMERY OF THE UTILITY MODEL

The weak point to current roof planting system, the utility model provides a roof planting system that controllable formula supplied water is equipped with retaining drainage sheet layer, can store the rainwater, and the rainwater of storing can supply water for the plant again, and effectual using water wisely has saved the expense of manual watering, can ensure the good growth of roof plant.

The water in the reservoir supplies water like planting soil layer, the planting soil and the reservoir are isolated by the filter layer, the support plate is arranged to support the filter layer above, and the small holes in the support plate can allow water flow to flow through, so that the water level in each position in the reservoir is kept uniform.

Furthermore, the slope of the roof structure layer is not higher than 3 degrees, and the slope of each layer above the roof structure layer is consistent with that of the roof structure layer. Because the roof is provided with the reservoir supplying moisture like soil, the slope of the roof is smaller and better, but if the absolute flat roof can not discharge the accumulated water on the roof, the slope of the roof with the angle not higher than 3 degrees can not influence the planting of the roof and can discharge the accumulated water on the roof.

Furthermore, a drain pipe and a water inlet pipe leading to the inside of the water storage tank are arranged on the outer side surface of the water storage tank, wherein the drain pipe is close to the upper edge of the water storage tank, and the water inlet pipe is arranged below the drain pipe. When the water quantity accumulated in the reservoir is close to the upper edge, the water can flow into the drain pipe and is discharged along the drain pipe; the inlet tube is connected with a municipal tap water pipe, and when the water level in the water storage tank is too low, water can be supplied to the top plants by injecting tap water.

Further, the inlet tube is horizontal rectangular pipeline, is equipped with the breakwater in the inlet tube, and breakwater one end articulates on the bottom surface in the inlet tube, and the breakwater middle part is connected through spring and inlet tube bottom surface, and the breakwater inclines to the direction of intaking, is equipped with level sensor on the one side of breakwater orientation cistern. When rivers were sufficient in the cistern, have rivers to overflow in the inlet tube, level sensor can sense rivers, and the water level reduces gradually and even exhausts the time, does not have rivers to flow into breakwater department gradually, and level sensor senses when the water level is less than a certain limit value, and control inlet valve opens, and rivers impact breakwater pushes down and finally flows into in the cistern, and the breakwater that the spring is in compression state can not influence the inflow of rivers.

Furthermore, the filter layer is a geotextile filter layer, the lower surface of the geotextile filter layer is connected with a plurality of water-absorbing cloth strips, and the lower ends of the water-absorbing cloth strips drop to the bottom of the reservoir. The geotechnical cloth filter layer does not directly contact with water in the reservoir, relies on the cloth strip that hangs down to slowly absorb the moisture in the pond, and the plant absorbs moisture according to its demand is automatic, can reach the effect of lasting trace drip irrigation, and is very useful to the growth of plant.

Furthermore, the roof heat-insulating layer is made of extruded polystyrene foam boards, and the thickness range is 50mm-100 mm.

Further, the waterproof layer is laid by using SBS waterproof coiled materials.

Compared with the prior art, the beneficial effects of the utility model are that: the water storage and drainage plate is arranged below the planting soil layer of the roof planting system, rainwater can be stored during rainfall, and accumulated water is drained along the drainage pipe arranged on one side of the reservoir when the water amount is excessive, so that the rotten roots and roof accumulated water caused by plant soaking are effectively avoided; when the rainwater of weather arid storage in the cistern consumed up, the water level inductor in the inlet tube can the signals, and is waterproof in to the cistern through the municipal administration water pipe of being connected with it, makes and is kept ponding in the cistern always, and the cloth that absorbs water of the downward drippage of filter layer bottom can be according to the automatic water absorption of the water storage capacity of plant, avoids artifical watering, and more is of value to vegetation.
