Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses an ecological roof in sponge city, including building roof 1, the edge step of building roof 1 is equipped with the eaves 11 that catchments, and the upper portion of eaves 11 that catchments outwards extends the slope setting gradually along the direction of keeping away from building roof 1.

The upper surface of building roof 1 is equipped with two piece at least waterproof layers 3 that the cross-section is the square through the concrete step, and the quantity of waterproof layer 3 is four in this embodiment, and the interval sets up between four waterproof layers 3 and forms catchment canal 4.

Referring to fig. 1 and 2, a polytetrafluoroethylene partition frame 2 is laid on the upper surface of each waterproof layer 3, and the size of the section of the partition frame 2 is equal to that of the waterproof layer 3. The bottom of each separation frame 2 is filled with a sand filter layer 22, a planting soil layer 21 for planting plants is filled above the sand filter layer 22, and the sand filter layer 22 is used for blocking soil and preventing the soil of the planting soil layer 21 from running off. The bottom of the side wall of each separating frame 2 is provided with a plurality of circular drainage holes 24 at intervals along the circumference of the separating frame 2, and the highest level of the water collecting eaves 11 is lower than the level of the drainage holes 24.

A circular water outlet 41 is formed in the water collecting channel 4, the water outlet 41 is communicated with a water storage tank 5 through a pipeline, the lower part of the water storage tank 5 is communicated with a water pump 6, a water spraying pipe 61 is communicated with the water pump 6, one end, far away from the water pump 6, of the water spraying pipe 61 penetrates through the surface of the planting soil layer 21, and an atomizing nozzle 62 is further installed at one end, far away from the water pump 6, of the water spraying pipe 61.

When raining, rainwater falls into the water collecting channel 4, rainwater in the water collecting channel 4 flows into the water storage tank 5 from the water outlet 41 to be collected and stored, when plants in the separation frame 2 need to be sprayed, the water pump 6 is started, and water in the water storage tank 5 is sprayed out from the atomizing nozzle 62 through the water spraying pipe 61 to spray and irrigate the planting soil layer 21. Through carrying out recycle to the rainwater, can save a large amount of water resources.

The separation frame 2 can limit the planting soil layer 21, so that the soil is prevented from being lost due to rainwater erosion, water in the separation frame 2 can permeate downwards through the sand filter layer 22 and is discharged from the drain hole 24, and the plants are prevented from being damaged due to a large amount of water left in the separation frame 2. The waterproof layer 3 makes the separation frame 2 and the water collecting channel 4 generate a height difference, so that water in the separation frame 2 can be conveniently drained, and because the highest level of the water collecting eaves 11 is lower than the height of the drain holes 24, the water in the drain holes 24 can be completely drained, and residues are avoided.

The upper surface of each waterproof layer 3 is gradually raised from the edge to the middle to form an arc surface, the lower surface of the separation frame 2 is gradually and upwards sunken from the edge to the middle to form an arc surface, and the lower surface of the separation frame 2 just can be matched with the upper surface of the waterproof layer 3. The arc-shaped arrangement of the lower surface of the separation frame 2 can guide the water in the separation frame 2, so that the water in the separation frame 2 can be conveniently drained from the water drainage holes 24.

The edge of planting soil layer 21 upper surface still lays and is used for carrying out the cobble area 23 fixed to planting soil layer 21, can prevent to plant the soil of soil layer 21 and pile up to both sides, makes planting soil layer 21 keep level and smooth.

A cylindrical filter cartridge 42 is detachably mounted in the drain port 41, a flange 421 is formed by extending the edge of the cartridge opening of the filter cartridge 42 outward in the horizontal direction, and the lower surface of the flange 421 abuts against the edge of the drain port 41. The filter box 42 is used for filtering rainwater, so that foreign matters are prevented from entering the water storage tank 5 to block the water pump 6, and the filter box 42 is detachably mounted, so that the filter box 42 is convenient to take out for cleaning and use.

The bottom of storage water tank 5 has a blow off pipe 51 along vertical direction intercommunication, installs blowoff valve 511 on the blow off pipe 51, and blow off pipe 51 is arranged in discharging the silt that carries in the rainwater from storage water tank 5, avoids silt to pile up in storage water tank 5 for a long time and leads to blockking up.

The upper portion level intercommunication of eaves 11 lateral wall that catchments has a drain pipe 12, and drain pipe 12 can be just about to hold water when full in the canal 4 that catchments with water and discharge, prevents that the canal 4 from taking place the overflow phenomenon.

The implementation principle of the embodiment is as follows: collect the rainwater through setting up storage water tank 5 and store, spray the watering through water pump 6 with water pump 6 to atomizer 62 in the storage water tank 5 during the use, separate frame 2 through the setting and carry on spacingly to planting soil layer 21, prevent that soil from losing along with the erodeing of rainwater. The sand filter layer 22 is arranged to block the soil, so that the soil planted in the soil layer 21 is prevented from running off along with rainwater. The pebble belt 23 is arranged to fix the planting soil layer 21, so that soil of the planting soil layer 21 is prevented from being accumulated towards two sides, and the planting soil layer 21 is kept flat.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
