Description
Technical Field
[0001] The utility model belongs to the technical field of urban construction, and in particular relates to a garden greening ecological drainage composite structure. Background Art
[0002] In urban construction, the garden design required for garden construction is much more complicated than the requirements for urban road construction. In urban roads, only road construction and drainage wiring need to be planned, but in gardens, in addition to road planning, reasonable arrangements are also required in planting greenery and drainage to meet the design and planning needs of green plants in the gardens. In addition to the load-bearing aspect, the gardens do not need to be comparable to urban road construction, but have higher requirements in other greening aspects. Moreover, the drainage design in the garden is more important. It is not just about draining water, but also about effectively utilizing water resources to feed back into green plant planting. In gardens, since most of the time people walk around in them, if water accumulates in the garden, it will cause inconvenience to walking. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a composite structure for ecological drainage of garden landscaping. By using the planting layer with the infiltration layer as the low point and inclined toward it, the accumulated water on the planting layer can be collected on the infiltration layer in case of rain. After penetrating through the grass layer, the planting soil layer and the gravel layer from top to bottom, the accumulated water is collected in the discharge trough in the rammed earth layer. Under the action of gravity, the water in the discharge trough gradually penetrates into the blind pipe for discharge. The higher the accumulated water, the faster the infiltration speed. In the dry season, a certain volume of accumulated water can be accumulated in the discharge trough to avoid complete drying up, thereby realizing ecological composite drainage.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A composite structure for ecological drainage of garden landscaping comprises two groups of planting layers, an infiltration layer and a base wall panel, wherein the two groups of planting layers are arranged obliquely on the left and right sides of the infiltration layer with the infiltration layer as the low point, and a base wall panel is vertically arranged at the connection between the planting layer and the infiltration layer, and the bottom of the base wall panel abuts against the rammed earth layer; the infiltration layer comprises a grassland layer, a planting soil layer, a gravel layer and a rammed earth layer from top to bottom, a discharge trough is arranged in the rammed earth layer, the discharge trough is filled with gravel, a blind pipe is arranged in the middle of the discharge trough, the blind pipe and the discharge trough are not in contact with each other, and the space between the blind pipe and the discharge trough is filled with gravel, the blind pipe is provided with a plurality of through holes evenly distributed on the outer wall of the blind pipe, the outer wall of the blind pipe is covered with geotextile, a plurality of arched seepage holes are arranged at the bottom of the base wall panel, and the tops of the seepage holes do not exceed the planting soil layer.
[0006] The composite structure of ecological drainage for landscaping adopts this structure. The function of the infiltration layer in the middle is to infiltrate the accumulated water. The planting layers on the left and right ends are used to plant plants. The two groups of planting layers are set at an infiltration layer as the low point. The planting layers are inclined. When it rains or is watered, in addition to infiltrating into the planting layer, the excess water will flow from the planting layer to the infiltration layer due to gravity and accumulate at the upper end of the infiltration layer. The accumulated water will first infiltrate into the grass layer. Because of the lawn planted in the grass layer, the accumulated water will quickly pass through the lawn and infiltrate into the soil layer at the lower end, and enter the planting soil layer under the action of gravity. The planting soil layer is a mixed evenly sandy soil, and the planting soil layer is more Density can, on the one hand, prevent the roots of the lawn from passing through the soil layer, and on the other hand, it can block and store the accumulated water to a certain extent, slowing down the infiltration rate of the accumulated water. The accumulated water gradually seeps downward into the gravel layer. The gravel layer plays a major supporting role, providing the necessary supporting force for the upper grass layer and the soil layer. At the same time, due to the large gaps between the gravel, it will provide a larger volume space for the accumulated water, and the accumulated water that enters the gravel layer will flow downward quickly. The accumulated water will all accumulate on the upper end of the rammed earth layer. The dense rammed earth layer will make it difficult for the accumulated water to penetrate. The discharge trough in the rammed earth layer is used to collect the accumulated water in the gravel layer.
[0007] A blind pipe covered with a geotextile is arranged in the gravel layer, and a number of evenly distributed through holes are arranged on the blind pipe. The blind pipe is arranged in the middle of the discharge trough and does not contact the discharge trough. When water accumulates in the discharge trough, since the blind pipe is mainly arranged in the form of drilling holes on a corrugated pipe or a plastic pipe, the geotextile wrapped outside the blind pipe is soaked in the accumulated water and acts as a filter membrane to perform preliminary filtration of the accumulated water. When the accumulated water in the gravel layer reaches a height close to that of the planting soil layer, the water pressure on the geotextile increases under the action of the gravity of the water, and the water will be pressed into the through holes of the blind pipe. The blind pipe achieves the effect of discharging excessive accumulated water, thereby reducing the groundwater pressure and removing excess water. When the water level drops, the gravity of the water is not enough to press the water on the geotextile into the through holes, and the accumulated water can be stored in the gravel layer, and the water in the gravel layer can be reverse osmosis to the planting layer to supply water to the plants.
[0008] Since most of the accumulated water enters and accumulates from the infiltration layer, the long-term flushing of water from the planting layer may cause the grass layer and the soil layer above the infiltration layer to collapse onto the planting layers on both sides. Moreover, if a walkway is laid on the grass layer, it is more likely to cause collapse when people walk frequently. Therefore, a base wall panel that is downwardly abutted against the rammed earth layer is provided at the connection between the infiltration layer and the planting layer. The supporting effect of the base wall panel ensures that it is difficult for the grass layer and the soil layer to cross the base wall panel, thereby achieving internal stability. A number of arched seepage holes are provided at the bottom of the base wall panel, and the upper ends of the seepage holes do not exceed the soil layer, so that the upper end of the base wall panel can maintain the supporting force for the grass layer and the soil layer, and the lower end of the base wall panel can use the gravel layer and the rammed earth layer as upward support to ensure the stability of the base wall panel, and the excess water in the planting layer can enter the gravel layer through the seepage holes.
[0009] Furthermore, the thickness ratio of the grassland layer, the soil layer and the gravel layer is 3:1:1.
[0010] Compared with the prior art, the utility model has the advantages that the accumulated water can be gathered to the upper end of the infiltration layer through the inclined planting layer, and then the grass layer and the planting soil layer will initially infiltrate the accumulated water until it enters the gravel layer for water storage. The accumulated water will infiltrate downward until it accumulates in the discharge trough. The accumulated water is pressed on the geotextile by gravity, and the accumulated water is infiltrated into the blind pipe for discharge of excess water. When the water level drops, the accumulated water can be accumulated in the gravel layer for water storage to meet the infiltration water supply needs of the planting layer. In order to avoid the collapse of the grass layer and the planting soil layer, a base wall panel is set to provide the necessary support force. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

The two groups of planting layers 1 are arranged obliquely on the left and right sides of the infiltration layer 2 with the infiltration layer 2 as the low point. A base wall panel 25 is vertically arranged at the connection between the planting layer 1 and the infiltration layer 2. The bottom of the base wall panel 25 abuts on the rammed earth layer 24. The infiltration layer 2 is composed of a grass layer 21, a planting soil layer 22, a crushed stone layer 23 and a rammed earth layer 24 from top to bottom. A discharge groove 241 is arranged in the rammed earth layer 24. Filled with gravel, a blind pipe 242 is provided in the discharge trough 241, and the blind pipe 242 is arranged in the middle of the discharge trough 241. The blind pipe 242 and the discharge trough 241 do not contact each other, and the blind pipe 242 and the discharge trough 241 are filled with gravel. The blind pipe 242 is provided with a plurality of through holes 243 evenly distributed on the outer wall of the blind pipe 242, and the outer wall of the blind pipe 242 is covered with geotextile. The bottom of the base wall panel 25 is provided with a plurality of arched seepage holes 251, and the top of the seepage hole 251 does not exceed the planting soil layer 22.
[0019] Furthermore, the thickness ratio of the grassland layer 21, the soil layer 22, and the gravel layer 23 is 3:1:1.
[0020] Description of the working method of this utility model:
[0021] The composite structure of landscaping ecological drainage adopts this structure. The infiltration layer 2 in the middle is used to infiltrate the accumulated water. The planting layers 1 at the left and right ends are used to plant plants. The two groups of planting layers 1 take the infiltration layer 2 as the low point. The planting layers 1 are inclined. When it rains or is watered, in addition to infiltrating into the planting layer 1, the excess water will flow from the planting layer 1 to the infiltration layer 2 due to gravity and accumulate at the upper end of the infiltration layer 2. The accumulated water will first infiltrate into the grass layer 21. Because the grass layer 21 is planted with lawn, the accumulated water will quickly pass through the lawn and infiltrate into the soil layer at the lower end. , and enters the planting soil layer 22 under the action of gravity. The planting soil layer 22 is a uniformly mixed sand. Compared with the grass layer 21, the planting soil layer 22 will be denser. On the one hand, it can prevent the roots of the lawn from passing through the planting soil layer 22. On the other hand, it can block and store the accumulated water to a certain extent, slowing down the infiltration speed of the accumulated water. The accumulated water that gradually penetrates downward enters the gravel layer 23. The gravel layer 23 plays a major supporting role, providing the necessary supporting force for the upper grass layer 21 and the planting soil layer 22. At the same time, due to the large gaps between the gravels, it will provide a larger volume space for the accumulated water. , and the accumulated water entering the gravel layer 23 will flow downward quickly, and the accumulated water will all accumulate on the upper end of the rammed earth layer 24. The dense rammed earth of the rammed earth layer 24 is dense, and the accumulated water will be difficult to penetrate. The discharge trough 241 in the rammed earth layer 24 is used to collect the accumulated water in the gravel layer 23. The layer thickness ratio of the grassland layer 21, the planting soil layer 22, and the gravel layer 23 is 3:1:1. The purpose is to allow the grassland layer 21 to have enough depth for filling with planting soil, so that it can retain a certain water storage capacity on the planting soil layer 22, avoiding the grassland layer 21 from being filled with planting soil in the case of heavy rain. It is not deep enough to affect the infiltration and accumulation of water. After all, the infiltration speed of the soil layer 22 is not very fast, and the thickness ratio of the soil layer 22 and the gravel layer 23 is consistent. When the gravel layer 23, the soil layer 22 and the grass layer 21 are all filled with water, it means that the drainage composite structure has exceeded its own carrying capacity. At this time, the accumulated water will accumulate on the upper end of the grass layer 21. The discharge of excess water through surface drainage will have a better discharge effect. At the same time, the presentation of the appearance can remind people passing by that the place has exceeded the water storage carrying capacity and avoid people passing by.
[0022] A blind pipe 242 covered with a geotextile is arranged in the gravel layer 23. The blind pipe 242 is provided with a plurality of evenly distributed through holes 243. The blind pipe 242 is arranged in the middle of the discharge trough 241 and does not contact the discharge trough 241. When water accumulates in the discharge trough 241, since the blind pipe 242 is mainly arranged in the form of drilling holes on a corrugated pipe or a plastic pipe, the geotextile wrapped outside the blind pipe 242 is soaked in the accumulated water and acts as a filter membrane to perform preliminary filtration of the accumulated water. When the accumulated water in the gravel layer 23 reaches the contact point, the geotextile is filtered out. When the height is close to the planting soil layer 22, the water pressure on the geotextile increases under the action of the gravity of the water, and the water will be pressed into the through hole 243 of the blind pipe 242. The blind pipe 242 can achieve the effect of discharging excessive accumulated water, thereby reducing the groundwater pressure and removing excess water. When the water level drops, the gravity of the water is not enough to press the water on the geotextile into the through hole 243, and the accumulated water can be accumulated in the gravel layer 23 for storage. The water in the gravel layer 23 can be reverse osmosis to the planting layer 1 to supply water to the plants.
[0023] Since the accumulated water mostly enters and accumulates from the infiltration layer 2, it is very likely that the grass layer 21 and the soil layer 22 at the upper end of the infiltration layer 2 will collapse onto the soil layers 1 on both sides if the water flows through the planting layer 1 for a long time. Moreover, if a walkway is laid on the grass layer 21, it is more likely to collapse when people walk frequently. Therefore, a base wall plate 25 that abuts against the rammed earth layer 24 is provided at the connection between the infiltration layer 2 and the planting layer 1. The support function of the base wall plate 25 ensures that the grass layer 21 and the soil layer 1 are supported. 22 is difficult to pass over the base wall panel 25, so as to achieve internal stability. A number of arched seepage holes 251 are arranged at the bottom of the base wall panel 25, and the upper ends of the seepage holes 251 do not exceed the planting soil layer 22, so that the upper end of the base wall panel 25 can maintain the supporting force for the grass layer 21 and the planting soil layer 22, and the lower end of the base wall panel 25 can use the gravel layer 23 and the rammed earth layer 24 as the upward supporting force to ensure the stability of the base wall panel 25, and the excess water in the planting layer 1 can enter into the gravel layer 23 through the seepage holes 251.
[0024] The beneficial effect of the utility model is that the accumulated water can be gathered to the upper end of the infiltration layer 2 through the inclined planting layer 1, and then the grass layer 21 and the planting soil layer 22 will initially infiltrate the accumulated water until it enters the gravel layer 23 for water storage. The accumulated water will infiltrate downward until it accumulates in the discharge trough 241. The accumulated water is pressed on the geotextile by gravity, and the accumulated water infiltrates into the blind pipe 242 for discharge of excess water. When the accumulated water level drops, the accumulated water can be accumulated in the gravel layer 23 for water storage to meet the infiltration water supply needs of the planting layer 1. In order to avoid the collapse of the grass layer 21 and the planting soil layer 22, a base wall panel 25 is provided to provide necessary support.
[0025] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
