Description

Technical Field

[0001] This utility model relates to the technical field of planting mats, and in particular to a landscaping planting mat. Background Technology

[0002] Planting mats, as a highly efficient tool for vegetation cultivation and ecological protection, play a vital role in modern ecological construction, agricultural production, and urban greening. They provide a stable environment for vegetation growth, effectively protect surface soil, and reduce soil erosion. Especially in slope stabilization and sandy land greening, they can quickly establish vegetation cover and improve the regional ecological environment. At the same time, planting mats can also increase vegetation survival rates and shorten vegetation growth cycles, making them invaluable for improving land utilization and beautifying the environment.

[0003] Currently, common planting mats mainly consist of a base layer, a water-retaining layer, and a permeable layer. The base layer is the core area for vegetation growth, providing space for plant roots to attach and grow, while also bearing the important function of nutrient supply. The water-retaining layer is responsible for storing water, ensuring that the vegetation can obtain continuous moisture and maintain normal physiological activities when water supply is insufficient. The permeable layer's function is to allow excess water to permeate downwards, preventing excessive water accumulation on the surface, thereby maintaining the water balance of the planting environment.

[0004] However, this structural design has certain flaws; due to the lack of sufficient gaps between the water storage layer and the permeable layer, air cannot circulate smoothly between the two layers, which directly affects the growth of the plant roots; the roots are in a hypoxic environment for a long time, which not only inhibits their normal respiration and nutrient absorption, but also easily causes the roots to become entangled, seriously hindering the healthy growth of the vegetation.

[0005] In addition, this structural design makes it difficult to create an effective water flow drop; the insufficient water flow drop means that the water lacks sufficient power during the infiltration process, resulting in low water infiltration efficiency; when there is a lot of rainfall, the excess water cannot infiltrate into the ground through the permeable layer in time, and it is very easy to form water accumulation on the surface of the planting carpet; water accumulation will not only further aggravate the problem of root hypoxia, but may also cause diseases such as root rot in vegetation, which will have an adverse impact on the stability of the entire vegetation ecosystem. Utility Model Content

[0006] The purpose of this invention is to provide a garden greening planting mat that can form gaps between the water storage layer and the permeable layer to facilitate air circulation and create a water flow drop, thereby promoting the downward infiltration of excess water and effectively preventing water accumulation.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A landscaping planting mat is composed of at least two planting mat units; each planting mat unit includes a base layer, a water storage layer, a permeable layer and a drainage layer arranged sequentially from top to bottom, and a support layer disposed between the water storage layer and the permeable layer; the support layer forms multiple independent spaces inside for the growth of plant roots, and the support layer is provided with a fixing structure on its surrounding edges for fixing after the edges of the support layers of two adjacent planting mat units overlap.

[0009] Based on the above technical solution, the present invention can be improved as follows:

[0010] Furthermore, the fixing structure includes a ground nail provided on one side edge of the support layer and a nail hole provided on the other side edge of the support layer; the ground nail on the support layer of one of the planting blanket units can pass through the nail hole on the support layer of the adjacent planting blanket unit and be inserted into the soil to complete the fixing.

[0011] Furthermore, the ground nail has a movable cavity inside, and slots communicating with the movable cavity are opened on opposite sides of the ground nail, with barbs provided at the slots; a movable rod is movably provided inside the ground nail, and a force-applying part is provided on the movable rod. When the movable rod moves upward inside the ground nail, the force-applying part can push the movable end of the barb outward of the ground nail and insert it into the soil.

[0012] Furthermore, the movable rod is provided with extensions extending beyond the ground nail on opposite sides, and the ground nail is provided with clearance grooves on opposite sides for the extensions to pass through; when the ground nail on the support layer of one of the planting mat units passes through the nail hole on the support layer of the adjacent planting mat unit, the extension contacts the edge of the support layer it passes through, and moves upward along the clearance groove as the ground nail continues to penetrate, thereby driving the movable rod to rise inside the ground nail.

[0013] Furthermore, the barb has a force-receiving part on its inner side, and the force-receiving part forms an inclined guide surface on the side away from the inner side of the barb; the force-applying part is a conical structure with a diameter that gradually increases from the top to the bottom; when the movable rod moves upward, the force-applying part on the movable rod can move upward along the guide surface on the force-receiving part and form a thrust parallel to the radial direction of the ground nail, so that the movable end of the barb is pushed outward of the ground nail.

[0014] Furthermore, the edge portion of the support layer pierced by the ground nail is provided with a fitting groove on the overlapping surface, and the fitting groove is connected to the nail hole; by the force application part on the movable rod and the fitting groove cooperating, the overlapping surfaces of the edge portions of the support layers of two adjacent planting blanket units can fit together when overlapping.

[0015] Furthermore, the base layer is composed of a mixture of lightweight nutrient soil and perlite.

[0016] Furthermore, the water storage layer is composed of a mixture of bamboo charcoal particles and moss ash.

[0017] Furthermore, the permeable layer includes a first sub-layer and a second sub-layer disposed at the bottom of the first sub-layer; the first sub-layer is composed of coconut fiber, and the second sub-layer is composed of rubber particles.

[0018] Furthermore, the drainage layer is made of non-woven fabric, and water-guiding grooves are provided on the non-woven fabric.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] Each planting mat unit in this invention includes, from top to bottom, a base layer, a water storage layer, a permeable layer, and a drainage layer, with a support layer between the water storage layer and the permeable layer. The support layer has a certain thickness, creating gaps between the water storage layer and the permeable layer to facilitate air circulation, providing sufficient oxygen for the plant roots and meeting their respiration needs. The support layer also forms multiple independent spaces within itself, allowing the plant roots to extend and grow freely, preventing root entanglement and crowding, and promoting nutrient and water absorption, thus fostering healthy plant growth. Simultaneously, the gaps between the water storage layer and the permeable layer create a water flow gradient, facilitating the downward infiltration of excess water from the water storage layer and effectively preventing waterlogging.

Detailed Implementation

[0033] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These descriptions are intended to aid in understanding the utility model but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] See Figures 1 to 10 This embodiment relates to a landscaping planting mat, which is composed of at least two planting mat units spliced ​​together. Each planting mat unit includes a base layer 1, a water storage layer 2, a permeable layer 3, and a drainage layer 4 arranged sequentially from top to bottom. During installation, the surface of the area to be installed is first leveled, and then each planting mat unit is laid flat on the surface. The base layer 1 is the top layer, used for planting vegetation, and the drainage layer 4 is the bottom layer. The drainage layer 4 is connected to the surface to drain the water that seeps downward into the soil of the surface.

[0035] Specifically, the base layer 1 is composed of a mixture of lightweight nutrient soil and perlite. The lightweight nutrient soil contains organic matter, such as peat and humus, and has strong water retention capacity, allowing it to absorb water for slow absorption by the plants. The porous structure of perlite can store some water, releasing it when the nutrient soil is insufficient, forming a water-retention and water-release buffer mechanism. The organic matter and nutrients in the lightweight nutrient soil, such as nitrogen, phosphorus, and potassium, can be adsorbed by the porous structure of perlite, reducing nutrient loss due to watering, i.e., a slow-release effect, and prolonging the duration of fertility. At the same time, the loose structure facilitates the spread of plant roots, making it easier to absorb nutrients and improving fertilizer utilization. Perlite has a low density, approximately 0.1-0.2 g / cm³, which can significantly reduce the overall weight of the planting mat unit. In this embodiment, perlite accounts for 20%-40%, and nutrient soil accounts for 60%-80%.

[0036] Water storage layer 2 is composed of a mixture of bamboo charcoal particles and moss ash. The bamboo charcoal particles have large pores, which can store a large amount of free water, while the moss ash has small pores that can adsorb bound water, forming a graded water storage system that significantly increases the total water storage capacity. After the moss ash fills the gaps between the bamboo charcoal particles, it reduces the loss of water due to rapid infiltration by gravity and prolongs the retention time of the water. The polar groups of the bamboo charcoal particles themselves work synergistically with the minerals in the moss ash to enhance the overall hydrophilicity of the material, making it easier for water to be adsorbed rather than evaporated. At the same time, the low thermal conductivity of the mixture can slow down the evaporation of water caused by temperature rise. The air permeability of the bamboo charcoal particles avoids the defect of caking when the moss ash is used alone, preventing water accumulation and oxygen deficiency in the plant roots. The water retention capacity of the moss ash compensates for the defect of easy water loss when the bamboo charcoal particles are used alone. In this embodiment, the proportion of bamboo charcoal particles is 60%-80%, and the proportion of moss ash is 20%-40%.

[0037] The permeable layer 3 includes a first sub-layer 301 and a second sub-layer 302 located at the bottom of the first sub-layer 301. The first sub-layer 301 is composed of coconut fiber, and the second sub-layer 302 is composed of rubber granules. Multiple irregular small gaps are formed between the coconut fibers, which can guide excess water to infiltrate downwards and avoid water accumulation. The coconut fibers can absorb some water and, through capillary action, retain an appropriate amount of water for the roots of plants to absorb during drainage, avoiding excessive drying due to rapid drainage and achieving a balance between drainage and water retention. The coconut fibers have a certain degree of elasticity and are not easily compacted by watering, trampling, or plant growth, thus maintaining the void structure between the coconut fibers for a long time and ensuring drainage stability. At the same time, the coconut fibers can buffer water flow and reduce soil loss. The gaps formed between the rubber granules are larger than those between the coconut fibers, allowing them to quickly accept a large amount of water and directly infiltrate to the lower layers. The rubber granules are chemically stable, corrosion-resistant, and acid and alkali-resistant, and are not easily compressed or decomposed, thus maintaining the void structure between the rubber granules for a long time and improving permeability efficiency.

[0038] The drainage layer 4 is made of non-woven fabric, and water-guiding grooves 401 are provided on the non-woven fabric. Water falls on the non-woven fabric and is guided by the water-guiding grooves 401 to drain away in a preset direction, effectively improving drainage efficiency. The water-guiding grooves 401 can enhance the tensile and tear resistance of the non-woven fabric and are not easily damaged by the growth of plant roots. In this embodiment, the water-guiding grooves 401 are long grooves with a V-shaped cross-section. The water-guiding grooves 401 are parallel to each other and are evenly spaced along the length of the non-woven fabric. The water-guiding grooves 401 form openings at the edges of the non-woven fabric so that water can drain into the soil from the openings.

[0039] A honeycomb support frame 5 is installed between the water storage layer 2 and the permeable layer 3. The honeycomb support frame 5 is composed of multiple interconnected hexagonal cells, which can evenly distribute the force on the planting mat unit when it is trampled to the entire planting mat unit, effectively preventing local collapse caused by excessive local stress and significantly improving the overall strength of the planting mat unit. Due to the certain thickness of the honeycomb support frame 5, gaps are formed between the water storage layer 2 and the permeable layer 3 to facilitate air circulation, providing sufficient oxygen for the plant roots and meeting their respiration needs. At the same time, each cell on the honeycomb support frame 5 forms a relatively independent space, allowing the plant roots to extend and grow freely within that space, avoiding root entanglement and crowding, which is conducive to the absorption of nutrients and water by the roots and promotes healthy plant growth. In addition, the gaps between the water storage layer 2 and the permeable layer 3 create a corresponding drop in water flow, effectively promoting the downward infiltration of excess water in the water storage layer 2 and effectively preventing water accumulation.

[0040] It should be noted that in this embodiment, a honeycomb support frame 5 is used as the support layer. Depending on actual needs, other support layers that are suitable for forming gaps between the water storage layer 2 and the permeable layer 3 and have multiple independent spaces suitable for the growth of plant roots can also be used instead, such as a grid frame. At the same time, in order to prevent a large amount of bamboo charcoal particles and moss ash mixture from falling into the honeycomb support frame 5, a mesh (not shown in the figure) is set at the bottom of the water storage layer 2. The mesh has multiple mesh holes, and the bamboo charcoal particles and moss ash mixture are blocked by the mesh, while excess water can permeate downward through the mesh holes of the mesh.

[0041] In this embodiment, the honeycomb support frame 5 is made of elastic plastic, which has strong corrosion resistance and can maintain the gap between the water storage layer 2 and the permeable layer 3 for a long time. At the same time, due to the elasticity of the elastic plastic, the planting mat unit can naturally unfold and flatten under the action of elasticity during the laying process, thereby reducing wrinkles. It should be noted that the thickness of the honeycomb support frame 5 should be designed according to the actual gap required between the water storage layer 2 and the permeable layer 3. In addition, the honeycomb support frame 5 can also be replaced by other corrosion-resistant elastic materials in the prior art.

[0042] The honeycomb support frame 5 forms an edge around its perimeter. During installation, the honeycomb support frames 5 of two adjacent planting mat units overlap at the edge and are fixed by a fixing structure. After installation, a gap is formed between two adjacent planting mat units, and soil is filled into the gap to cover the fixing structure, so that the installed planting mat remains flat. For ease of description, the edge on one side of the honeycomb support frame 5 is named the first edge 501, and the edge on the opposite side of the honeycomb support frame 5 is named the second edge 502. During installation, the first edge 501 of the honeycomb support frame 5 of one planting mat unit overlaps the second edge 502 of the honeycomb support frame 5 of the adjacent planting mat unit.

[0043] The fixing structure includes ground nails 6 on the first edge portion 501 and nail holes 7 on the second edge portion 502; the ground nails 6 on the honeycomb support frame 5 of one of the planting blanket units can pass through the nail holes 7 on the honeycomb support frame 5 of the adjacent planting blanket unit and be inserted into the soil to complete the fixing.

[0044] The ground nail 6 is made of hard plastic. Compared with the ground nail 6 made of metal, the ground nail 6 in this embodiment has strong corrosion resistance and can keep the planting carpet fixed for a long time. The bottom of the ground nail 6 forms a nail tip, and the top of the ground nail 6 is connected to the edge of the honeycomb support frame 5 by heat fusion. The planting carpet unit can be limited and fixed by the cooperation of the ground nail 6 and the nail hole 7, thereby improving the laying efficiency.

[0045] The ground stake 6 has a hollow structure, forming a movable cavity inside. The ground stake 6 has slots 601 on opposite sides connecting to the movable cavity, and a barb 8 is provided at each slot 601. The bottom end of the barb 8 connects to the bottom wall of the slot 601, and the top end of the barb 601 is a movable end, forming a gap with the top wall of the slot 601. The barb 8 has an outer surface and an inner surface. A force-bearing part 801 is provided on the inner surface of the barb 8. The force-bearing part 801 extends upward at an angle to the inner surface of the barb 8, and an inclined guide surface is formed on the side of the force-bearing part 801 away from the inner surface of the barb 8. Under normal conditions, the outer surface of the barb 8 and the outer surface of the ground stake 6... The sides are flush, and the force-bearing part 801 is located inside the ground nail 6; a movable rod 9 is movably arranged in the movable cavity inside the ground nail 6, and a force-applying part 901 is provided near the bottom of the movable rod 9. The force-applying part 901 is a conical structure with a diameter that gradually increases from the top to the bottom. The top of the movable rod 9 has extensions 902 on opposite sides, and the extensions 902 extend out of the ground nail 6; the ground nail 6 has clearance grooves 602 on opposite sides, through which the extensions 902 on the movable rod 9 can pass. The clearance grooves 602 are elongated grooves parallel to the axis of the ground nail 6, and the extensions 902 on the movable rod 9 can move along the clearance grooves 602 on the ground nail 6.

[0046] When the ground nail 6 on one of the honeycomb support frames 5 passes through the nail hole 7 on the adjacent honeycomb support frame 5, the extension 902 on the movable rod 9 contacts the second edge 502 on the honeycomb support frame 5 through which it passes. As the ground nail 6 continues to penetrate, the extension 902 on the movable rod 9 moves upward along the relief groove 602, causing the movable rod 9 to rise inside the ground nail 6. The force-applying part 901 on the movable rod 9 abuts against the force-receiving part 801 on the barb 8 and moves upward along the guide surface on the force-receiving part 801, forming a thrust parallel to the radial direction of the ground nail 6 on the force-receiving part 801, so that the movable end of the barb 8 moves towards... The ground nail 6 is externally opened and inserted into the soil. When opened, the barb 8 and the ground nail 7 form a right-angled triangle structure with a pointed bottom and a wide top, thereby improving the firmness of the planting mat unit. The bottom end of the barb 8 is provided with a folding groove 802 on the outer side, so that the movable end of the barb 8 can be folded outward along the folding groove 802 to complete the opening. The movable rod 9 forms a stop 903 at the end of the extension 902. The stop 903 is rectangular and its size is larger than that of the extension 902, which can increase the contact area with the second edge 502, so that the force is evenly distributed and thus stably drives the movable rod 9 to rise.

[0047] It should be noted that in this embodiment, the diameter of the nail hole 7 is slightly smaller than the outer diameter of the ground nail 6, so that the nail hole 7 and the ground nail 6 form an interference fit, effectively preventing loosening between the ground nail 6 and the nail hole 7, and keeping the planting carpet unit fixed for a long time. At the same time, in this embodiment, each planting carpet unit has multiple ground nails 6 on its first edge 501 and multiple nail holes 7 on its second edge 502. The ground nails 6 and nail holes 7 on two adjacent planting carpet units are matched one-to-one to form multiple fixing points, thereby further improving the firmness of the planting carpet unit. Depending on the actual situation, the planting carpet unit can also have ground nails 6 and nail holes 7 set on the other two opposite edges, so that the planting carpet units can be connected to each other in different directions. The length of the ground nail 6 should be greater than the total thickness of the water storage layer 2, the permeable layer 3 and the drainage layer 4, so that the ground nail 6 can be inserted into the soil when the planting unit is laid, ensuring the fixation of the planting carpet unit.

[0048] The overlapping surface of the second edge portion 502 is provided with a fitting groove 10 at the nail hole 7, and the fitting groove 10 is connected to the nail hole 7; by the force application part 901 on the movable rod 9 and the fitting groove 10 cooperating, the overlapping surfaces of the first edge portion 501 and the second edge portion 502 on the honeycomb support frame 5 of the two adjacent planting blanket units are made to fit together, so as to ensure that the planting blanket is flat after being laid.

[0049] It should be noted that after all the planting mat units are laid on the surface, the ground nails 6 in this embodiment need to be inserted individually into the nail holes 7 on the second edge 502 located at the edge of the surface to fix the second edge to the surface. After fixing, soil is laid to cover the ground nails 6 so that the laid planting mat remains flat.

[0050] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
