Description

Technical Field

[0001] The utility model relates to the technical field of sponge cities, and particularly relates to a sponge city landscape slope structure. Background Art

[0002] A sponge city means that the city can be like a sponge and has good "elasticity" in aspects such as adapting to environmental changes and coping with natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water, and when needed, the stored water is released and utilized.

[0003] The landscape slope is the greening and landscaping part of the sponge city. Through artificial slope stacking and then combined with greening planting, undulating landscape terrain is formed.

[0004] The problems existing in the prior art are: the artificial landscape slope does not have the function of storing rainwater. During rainy days, the rainwater is directly discharged, and during dry seasons, a large amount of water is required for irrigation, which does not meet the requirements of water absorption, storage, infiltration, and purification of the sponge city.

[0005] Moreover, as an artificial landscape slope, when stepped on by tourists, the soil surface turns over, and the green plants are extremely easy to be damaged, especially in the initial stage of green plant planting.

[0006] Therefore, it is necessary to improve the design of the artificial landscape slope structure so that it has the functions of water storage and rainwater reuse and can protect the green plants on the landscape slope. Content of the Utility Model

[0007] In order to solve the above technical deficiencies, the utility model provides a sponge city landscape slope structure.

[0008] The technical solution of the utility model: A sponge city landscape slope structure includes a slope soil body, a water storage tank, and a spraying device. A plurality of grid planting pads are covered on the slope soil body. The grid planting pad includes a vertically upper end and a vertically lower end. Along the direction from the vertically upper end to the vertically lower end, a plurality of planting grooves are arranged at intervals. A runoff channel passing through each planting groove is provided on the grid planting groove. The runoff channel is provided with an inlet communicating with the vertically upper end and an outlet communicating with the vertically lower end;

[0009] The plurality of grid planting pads are arranged in columns connected end to end in the vertical direction along the slope soil body. The inlet and outlet of adjacent runoff channels are butted in batches. A drainage channel is arranged in a ring along the contour at the bottom of the slope soil body. The slope soil body is covered by a plurality of columnar grid planting pads, and its runoff channel extends to the drainage channel. The drainage channel collects rainwater into the water storage tank, and the spraying device extracts the rainwater in the water storage tank to spray the slope soil body.

[0010] The above technical solution is adopted, by covering and laying a number of grid planting mats on the slope soil, which are made of environmentally friendly materials, such as high-density polystyrene or polypropylene, which are easy to plant, water-resistant, corrosion-resistant and durable. Green plants are planted in each planting trough, and the roots pass through the grid planting mats and take root in the soil. Through its covering and laying, the slope soil is firmly protected, and tourists step on it, avoiding soil damage and affecting green plants.

[0011] At the same time, the runoff channels installed on the planting mats guide rainwater and spray water to the various planting troughs for irrigation, while connecting and guiding excess rainwater to the drainage ditch, and then storing it in underground and semi-underground reservoirs. In periods of lack of rain and water, the irrigation slope soil is pumped out by the spraying equipment for recycling, thus achieving the purpose of a sponge city.

[0012] The utility model is further configured as follows: at each planting groove of the grid planting mat, an annular water storage groove is coaxially arranged on its periphery, and the runoff channel passes through each annular water storage groove, and the depth of the annular water storage groove is greater than the depth of the runoff channel.

[0013] By adopting the above technical scheme, an annular water storage trough is set up. Since its depth is greater than the runoff channel, after the rain stops and the spraying stops, some water will remain in the annular water storage trough instead of being diverted away. Combined with the slow water diversion of the non-woven fabric strips, or the setting of micro-pore leakage in the connecting planting trough, intermittent water replenishment can be provided for the green plants.

[0014] The utility model is further configured as follows: on the other side end surface of the grid planting mat relative to the runoff channel, an insertion end extending into the soil is arranged at the notch of each planting groove.

[0015] By adopting the above technical solution, the setting of the insertion end not only strengthens the bonding stability between the grid planting mat and the soil, but also forms a barrier to protect the soil around the planting trough.

[0016] Further configuration of the utility model: the plurality of planting troughs are staggeredly arranged from the vertical upper end to the vertical lower end, the runoff channel includes an inlet section, an outlet section, and a diversion section, the inlet section and the outlet section are straight grooves from the vertical upper end and the vertical lower end to the adjacent annular water storage trough, the diversion section is arranged between the annular water storage trough and another annular water storage trough, and is arranged in a "W" or "human" shape.

[0017] By adopting the above technical solution, rainwater and spray water can be fully diverted to each annular water storage tank through the structural design of the runoff channel.

[0018] Further setting of the present utility model: The grid planting pad is provided with hollow grooves running through it, and buckling grooves are arranged on both edges of the grid planting pad. Between adjacent two rows of grid planting pads arranged in columns, they are buckled and connected to each other by the buckling grooves, and adjacent two rows of grid planting pads arranged in columns are arranged with vertical dislocation.

[0019] With the above technical solution, through the structural design of the buckling groove, the overall connection stability is improved, and the staggered setting, as shown in the attached drawings of the specification Figure 2 As shown, two grid planting pads are jointly connected to the same grid planting pad on one side, improving its connection stability.

[0020] Further setting of the present utility model: The annular water storage tank is provided with non-woven fabric strips extending into the planting tank.

[0021] Further setting of the present utility model: An HDPE film, a drain pipe, and a geotextile are arranged between the slope soil body and the bottom surface, and the drain pipe guides the seepage water in the slope soil body to the reservoir.

[0022] With the above technical solution, the seepage water of the slope soil body is further intercepted and led back to the reservoir for reuse.

[0023] Further setting of the present utility model: The spraying device includes a water pump, a water delivery pipe, a spray head, and a time control switch. The time control switch starts the water pump regularly to guide the water in the reservoir to be sprayed onto the slope soil body.

[0024] Beneficial effects of the present utility model: Through the structural design of the artificial landscape slope structure, it has the function of rainwater guiding and recycling. By using the laid grid planting pads, it stabilizes the environment of the soil body and green plants, diverts rainwater, retains rainwater, and recycles rainwater, saving the maintenance cost of the landscape slope and improving the survival rate of green plants.

[0034] The following will introduce the present utility model in detail in conjunction with the drawings. As Figures 1-6 shown, a sponge city landscape slope structure includes a slope soil body 1, a reservoir 2, and a spraying device. A plurality of grid planting pads 3 are covered on the slope soil body 1. The grid planting pad 3 includes an upper vertical end 31 and a lower vertical end 32.

The runoff channel 34 is provided with an inlet communicating with the upper vertical end 31 and an outlet communicating with the lower vertical end 32;

[0035] The plurality of grid planting pads 3 are arranged in columns in a vertically connected end-to-end manner along the slope soil body 1. The inlets and outlets of adjacent runoff channels 34 are butted in batches. A drainage channel 21 is provided along the contour around the bottom of the slope soil body 1. The slope soil body 1 is covered by a plurality of columns of grid planting pads 3, and its runoff channel 34 extends to the drainage channel 21. The drainage channel 21 collects rainwater into the reservoir 2, and the spraying device extracts the rainwater in the reservoir 2 to spray the slope soil body 1.

[0036] A number of grid planting pads 3 are laid on the slope soil mass 1 by covering. They are made of environmentally friendly materials such as high-density polystyrene or polypropylene, which are convenient for planting, water-resistant, corrosion-resistant and durable. Green plants are planted in each planting groove 33, and the roots penetrate through the grid planting pad 3 and take root in the soil mass. Through its covering and laying, the slope soil mass 1 is firmly protected, and when tourists step on it, the soil mass is prevented from being damaged and affecting the green plants.

[0037] At the same time, the runoff channels 34 provided on each planting pad guide rainwater and sprinkler water to each planting groove 33 for irrigation, and at the same time connect and guide the excess rainwater to the drainage channel 21, and then store it in the underground or semi-underground reservoir 2. During the period of lack of rain and water, it is pumped out by the sprinkler equipment to irrigate the slope soil mass 1 for recycling, so as to achieve the purpose of a sponge city.

[0038] At each planting groove 33 of the grid planting pad 3, an annular water storage groove 35 is coaxially arranged on its periphery. The runoff channel 34 passes through each annular water storage groove 35, and the depth of the annular water storage groove 35 is greater than that of the runoff channel 34.

[0039] By setting the annular water storage groove 35, since its depth is greater than that of the runoff channel 34, after the rain stops and the sprinkler stops, a part of the water will remain in the annular water storage groove 35 and will not be drained away. Combined with the slow water diversion of the non-woven fabric strip or the micro-hole leakage form provided to connect the inside of the planting groove 33, it provides intermittent water supply for the green plants.

[0040] On the other end surface of the grid planting pad 3 opposite to the runoff channel 34, insertion ends 36 extending into the soil mass are arranged at the openings of each planting groove 33.

[0041] The setting of the insertion end 36 not only strengthens the combined stability of the grid planting pad 3 and the soil mass, but also forms a surrounding protection for the soil around the planting groove 33.

[0042] The several planting grooves 33 are arranged in a staggered manner along the direction from the vertical upper end 31 to the vertical lower end 32. The runoff channel 34 includes an inlet section, an outlet section, and a diversion section. The inlet section and the outlet section are straight grooves from the vertical upper end 31 and the vertical lower end 32 to the adjacent annular water storage groove 35, and the diversion section is arranged between the annular water storage groove 35 and another annular water storage groove 35, and is arranged in a "W" or "human" shape.

Between two adjacent rows of the grid planting mats 3 arranged in columns, they are fastened and connected to each other by the fastening grooves 38, and two adjacent rows of the grid planting mats 3 arranged in columns are arranged with a vertical dislocation.

[0045] Through the structural design of the fastening grooves 38, the overall connection stability is improved, and the staggered arrangement, as shown in the attached instructions Figure 2 As shown, two grid planting mats 3 are jointly connected to the same grid planting mat 3 on one side, improving their connection stability.

[0046] A non-woven fabric strip extending into the planting groove 33 is arranged in the annular water storage tank 35.

[0047] An HDPE film 4, a drain pipe 5, and a geotextile 6 are arranged between the slope soil body 1 and the bottom surface, and the drain pipe guides the seepage water in the slope soil body 1 to the reservoir 2.

[0048] Further intercept the seepage water of the slope soil body 1 and lead it back to the reservoir 2 for reuse.

[0049] The spraying device includes a water pump, a water delivery pipe, a spray head, and a time control switch. The time control switch starts the water pump regularly to guide the water in the reservoir 2 to be sprayed onto the slope soil body 1.
