Description

Technical Field

[0001] The utility model relates to the technical field of garden greening, in particular to a garden landscape green belt. Background Art

[0002] In the construction of gardens, it is essential to build green belts to increase the ornamental value of the gardens. A variety of plants are often planted in green belts to increase the diversity of green belts and improve their ornamental value. Usually, the plants in green belts can be divided into tall trees and low shrubs or flowers and plants, which increase the height and level of green belts to improve the visual perception.

[0003] When constructing existing garden green belts, multiple layers of soil with uniform thickness and different functions are usually laid, and vegetation is planted directly in the nutrient soil on the surface. However, it does not take into account that the roots of vegetation are large and small. The roots of vegetation with large root systems can extend deep into the nutrient soil, while the roots of vegetation with small root systems only extend into shallower soil. The deeper soil below it is not used, resulting in a waste of nutrient soil.

[0004] In addition, the soil layer of the existing green belts cannot effectively retain rainwater, and more well water or river water is needed to irrigate the green belts, which is not conducive to saving water resources. Utility Model Content

[0005] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a garden landscape green belt.

[0006] The technical solution of this utility model is as follows:

[0007] A garden landscape green belt, comprising a base soil layer, an aquifer layer covering the base soil layer, an infiltration layer arranged above the aquifer layer, the aquifer layer and the infiltration layer both being wavy, extending along the length direction of the green belt, and symmetrically arranged up and down, and a nutrient soil layer covering the infiltration layer;

[0008] A water storage space is formed between the trough of the aquifer and the crest of the corresponding permeable layer above it. The water storage space is connected to the nutrient soil layer above and on both sides thereof through a water absorption pipe, and a water absorption core is arranged in the water absorption pipe;

[0009] Vertical retaining walls are set on both sides of the green belt, blocking the aquifer, infiltration layer and nutrient soil layer.

[0010] Among them, the area above the trough of the aquifer is used to plant tall trees, while the area above the crest is used to plant low shrubs or flowers and plants, so that the nutrient soil above the aquifer can be fully utilized.

[0011] In addition, the space under low shrubs or flowers and plants is used as water storage space to store rainwater, making full use of the underground space of the green belt. At the same time, the stored rainwater can be fed back to the nutrient soil layer through suction pipes and water absorption cores to provide growth for trees, flowers and plants. This not only reduces the number of watering times, but also greatly saves water consumption during watering.

[0012] In the above scheme, the aquifer and the infiltration layer are both trapezoidal in shape, so as to provide good support for the nutrient soil layer. At the same time, the top of the wave crest of the infiltration layer is flat, which can make the thickness of the nutrient soil above it uniform and correspond to the thickness required for shrubs or flowers and plants, thereby minimizing the waste of nutrient soil.

[0013] In order to adapt to the growth needs of trees, the crest width of the infiltration layer is greater than its trough width, so as to provide a larger spacing space for the growth of trees.

[0014] Preferably, the inclination angles of the slopes on both sides of the trough of the water seepage layer are 45-60 degrees to increase the utilization rate of the soil.

[0015] In the present application, a distance is provided between the aquifer and the seepage layer, a plurality of water storage spaces are interconnected, and are connected to the ground through a vertical shaft, and a support is provided between the aquifer and the seepage layer. When rainfall is low, water can be added to the water storage space through the vertical shaft to maintain the growth of vegetation. In addition, by adding water to the underground water storage space instead of watering from the ground, water evaporation can be avoided, so that water can be fully used for plant growth and water consumption can be reduced.

[0016] Preferably, the support is an irregular-shaped stone filler, which can better support the water seepage layer and nutrient soil layer above it. At the same time, due to the irregular surface of the stone, after the stone is filled, there are gaps between the stones, which can be used for rainwater storage and flow.

[0017] In addition, the upper part of the slopes on both sides of the trough of the water seepage layer is the water seepage section, and the rest of the water seepage layer is the non-water seepage section. When the rainfall is small, the rainwater is directly retained in the lower part of the trough of the water seepage layer to moisten the nutrient soil. When the rainfall is large and exceeds the water storage capacity of the lower part of the trough of the water seepage layer, the rainwater infiltrates into the water storage space through the water seepage section to avoid excessive water storage above the water seepage layer, which causes the roots of plants to be soaked in water and affects their growth.

[0018] In order to prevent the nutrient soil from moving with the infiltration of rainwater, a number of soil-fixing plates are arranged at intervals along the extension direction of the upper surface of the seepage layer to reinforce the nutrient soil. The soil-fixing plates are perpendicular to the upper surface of the seepage layer, and both ends extend horizontally to the retaining wall.

[0019] Preferably, soil fixing plates are provided on at least two sides of the top of the water seepage layer, and the height of the soil fixing plates is less than the distance between the top of the water seepage layer and the ground. When it rains, a small amount of rainwater can be directly retained on the top of the water seepage layer under the obstruction of the soil fixing plates for vegetation growth, thereby reducing the loss of nutrients in the nutrient soil.

[0020] In the present application, the absorbent core is preferably absorbent cotton.

[0021] The utility model provides a garden landscape green belt, which reduces the amount of soil corresponding to low shrubs or flowers and grasses through a corrugated water seepage layer, thereby improving the utilization rate of nutrient soil and avoiding waste of nutrient soil.

[0022] In addition, the space under low shrubs or flowers and plants is used as water storage space to store rainwater, making full use of the underground space of the green belt. At the same time, the stored rainwater can be fed back to the nutrient soil layer through suction pipes and water absorption cores to provide growth for trees, flowers and plants. This not only reduces the number of watering times, but also greatly saves water consumption during watering. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] 1. Base soil layer; 2. Aquifer; 3. Seepage layer; 31. Seepage section; 4. Nutrient soil layer; 5. Water storage space; 6. Water absorption pipe; 7. Water absorption core; 8. Vertical shaft; 9. Soil fixing board. DETAILED DESCRIPTION

[0027] like Figure 1 As shown, the embodiment of the utility model provides a garden landscape green belt, including a base soil layer 1, an aquifer 2 covering the base soil layer 1, a water seepage layer 3 arranged above the aquifer 2, the aquifer 2 and the water seepage layer 3 are both wavy, extending along the length direction of the green belt, and symmetrically arranged up and down, and a nutrient soil layer 4 covering the water seepage layer 3;

[0028] A water storage space 5 is formed between the trough of the aquifer 2 and the corresponding crest of the permeable layer 3 above it. The water storage space 5 is connected to the nutrient soil layer 4 above and on both sides thereof through a water absorption pipe 6. A water absorption core 7 is provided in the water absorption pipe 6.

[0029] Vertical retaining walls are arranged on both sides of the green belt, which are used to retain the aquifer 2, the seepage layer 3 and the nutrient soil layer 4.

[0030] The base soil layer 1 is used as a base and plays a supporting role, and is usually compacted to increase the strength of the layer.

[0031] The water storage layer 2 and the water permeable layer 3 are made of hard materials or cement materials, so that a stable water storage space 5 can be formed between the two. The water storage layer 2 is a completely impermeable layer, and the water permeable layer 3 is a permeable or partially permeable layer. This embodiment adopts a partially permeable layer. The specific structure and reasons will be described in detail later. But no matter which form, rainwater can penetrate into the water storage space 5. The water absorption pipe 6 can be a plurality of individual pipes, or a trident-shaped pipe. The lower end of the water absorption pipe 6 extends to the inner side of the trough of the water storage layer 2. The water absorption core 7 in the water absorption pipe 6 is preferably absorbent cotton, and the rainwater in the water storage space 5 is fed back to the nutrient soil layer 4 through the absorbent cotton to keep the nutrient soil layer 4 moist.

[0032] The nutrient soil layer 4 is used for planting grass and vegetation, and its top surface is flat, so that the nutrient soil at the corresponding trough position of the seepage layer 3 is thicker, and the nutrient soil at the corresponding peak position of the seepage layer 3 is thinner. Tall tree vegetation is planted in the nutrient soil above the trough of the seepage layer 3, and low shrubs or flowers and grass vegetation are planted in the nutrient soil above the peak of the seepage layer 3. The amount of nutrient soil is set according to the size and length of the root system of the planted grass and trees, which can reasonably and fully utilize the nutrient soil and avoid waste of nutrient soil.

[0033] In addition, the space under the low shrubs or flowers and plants is used as a water storage space 5 to store rainwater, making full use of the underground space of the green belt. At the same time, the stored rainwater can be fed back to the nutrient soil layer 4 through the water absorption pipe 6 and the water absorption core 7 to provide growth for trees, flowers and plants, etc., which not only reduces the number of watering times, but also greatly saves the water consumption during watering.

[0034] Specifically, in this embodiment, the aquifer 2 and the water seepage layer 3 are both trapezoidal in shape to adapt to the characteristics of the grass root system, which is large at the top and small at the bottom. In addition, the top of the water seepage layer 3 is flat, so that the thickness of the nutrient soil on its upper part is uniform and corresponds to the thickness required for shrubs or flowers and plants, which can provide good support for the nutrient soil layer 4 and minimize the waste of nutrient soil.

[0035] In order to meet the growth requirements of trees, the crest width of the water-permeable layer 3 is greater than the trough width thereof, so as to provide a larger spacing space for the growth of trees.

[0036] The inclination angle of the slopes on both sides of the trough of the infiltration layer 3 is preferably 45-60 degrees, which adapts to the shape of the tree roots and reduces the amount of unused nutrient soil under the low vegetation to increase the utilization rate of the soil.

[0037] Furthermore, a gap is provided between the aquifer 2 and the permeable layer 3, so that a plurality of water storage spaces 5 are interconnected and connected to the ground through a shaft 8. When rainfall is low, water can be added to the water storage space 5 through the shaft 8 to maintain the growth of vegetation. In addition, by adding water to the underground water storage space 5 instead of watering from the ground, water evaporation can be avoided, so that water can be fully used for plant growth and water consumption can be reduced.

[0038] A support is provided between the aquifer 2 and the seepage layer 3 to support the seepage layer 3. In this embodiment, the support is preferably an irregularly shaped stone filler. The stone filler can better support the seepage layer 3 and the nutrient soil layer 4 above it. At the same time, due to the irregular surface of the stone, after the stone is filled, there are gaps between the stones, which can be used for rainwater storage and flow.

[0039] In this embodiment, the water-permeable layer 3 is partially water-permeable. Specifically, the upper part of the slope on both sides of the trough of the water-permeable layer 3 is the water-permeable section 31, and the rest of the water-permeable layer 3 is the non-water-permeable section. The water-permeable section 31 can achieve the purpose of water seepage without soil leakage by setting fine and dense holes.

[0040] The water-permeable layer 3 of this embodiment can retain rainwater directly in the lower part of the trough of the water-permeable layer 3 when the rainfall is small, and directly be used to moisten the nutrient soil, thereby reducing the loss of nutrients in the nutrient soil with rainwater, and at the same time preventing the tree roots from being soaked and affecting the growth of trees.

[0041] When the rainfall is heavy and exceeds the water storage capacity of the lower part of the trough of the water-permeable layer 3, the rainwater seeps into the water storage space 5 through the water-permeable section 31 for storage, thereby preventing excessive water from being stored above the water-permeable layer 3, causing the roots of plants to be immersed in water and thus affecting their growth or even causing root rot.

[0042] In addition, in order to prevent the nutrient soil from moving with the infiltration of rainwater, a number of soil-fixing plates 9 are arranged at intervals along the extension direction of the upper surface of the seepage layer 3 to reinforce the nutrient soil. The soil-fixing plates 9 are perpendicular to the upper surface of the seepage layer 3, and both ends extend horizontally to the retaining wall. The height of the soil-fixing plates 9 is less than the distance between the top of the wave crest of the seepage layer 3 and the ground.

[0043] Preferably, soil fixing plates 9 are provided on at least two edges of the crest of the water seepage layer 3. The soil fixing plates 9 can not only fix the soil, but also retain a certain amount of rainwater on the upper part of the water seepage layer 3 and the lower part of the root system of the low vegetation when it rains, so as to provide vegetation growth and reduce the loss of nutrients in the nutrient soil. When the amount of rainwater exceeds the amount of water that the soil fixing plates 9 can retain, the rainwater overflows the soil fixing plates 9 and flows to the trough position of the water seepage layer 3, so as to prevent the roots of the low vegetation from being soaked in water and becoming sick or necrotic.
