Description

Technical Field

[0001] The utility model relates to the technical field of ecological mats, and particularly relates to a grid protection type modular ecological composite mat. Background Art

[0002] When laid, the ecological composite mat can be closely combined with the soil, which helps to reduce the erosion of the soil by factors such as rainfall, wind and water flow. At the same time, it can also support the growth and development of plants, improve the vegetation coverage rate of the ground surface, and thus improve the quality of the ecological environment.

[0003] A greening planting mat is disclosed in the Chinese utility model patent with the publication number of CN201640035U. Its structure includes a water storage and drainage mat with voids, and the voids are filled with nutrient solution or formulated soil particles required for plant growth; a barrier layer for waterproofing and root thorns prevention is further arranged below the water storage and drainage mat.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: the greening planting mat is only composed of a water storage and drainage mat and a barrier layer, and its body is too soft and the structure is relatively loose, prone to phenomena such as deformation, wrinkling and mat body dispersion, and the integrity and structural stability are poor. Therefore, it is necessary to improve and design the related technologies. Content of the Utility Model

[0005] In order to solve the above problems, the utility model provides a grid protection type modular ecological composite mat.

[0006] The above technical purpose of the utility model is achieved by the following technical solutions: a grid protection type modular ecological composite mat, which includes an upper layer, a middle layer and a lower layer arranged in sequence from top to bottom; the upper layer includes an upper geogrid and an upper geotextile compounded on the top of the upper geogrid; the middle layer is a nutrient soil layer mixed with green plant seeds; the lower layer includes a lower geogrid and a geocomposite fabric compounded on the bottom of the lower geogrid, and the geocomposite fabric is composed of a geomembrane and lower geotextiles compounded on the upper and lower surfaces of the geomembrane.

[0007] By adopting the above technical solutions, the nutrient soil layer is doped with seeds of flowers, grasses or other plants, and the nutrient soil is formulated according to the corresponding seeds. The upper geogrid and the upper geotextile act together, and the lower geogrid and the geocomposite fabric act together, ensuring the stability of the nutrient soil during use. Both the upper geotextile and the lower geotextile are excellent filtration and anti-filtration materials, having both ideal water permeability and being able to well prevent the loss of the nutrient soil in the ecological mat, providing good conditions for the growth of the internal green plant seeds. The upper geogrid and the lower geogrid play a good role as a framework, overcoming the defect that the ecological mat structure is unstable caused by the softness, easy deformation and wrinkling of the upper geotextile and the geocomposite fabric. Quilting connection is a process of sewing the outer layer and the inner core of a textile fabric, forming a simple and stable whole among the upper layer, the middle layer and the lower layer, providing a favorable guarantee for the greening and beautifying functions of the ecological mat. All kinds of materials in the ecological mat, such as the upper geogrid, the upper geotextile, the nutrient soil layer, the lower geogrid, and the geocomposite fabric, are pollution-free environmental protection materials. For the ecological mat used for a long time, as the plants in the mat, especially the plants with larger roots, grow, it will integrate with the underlying soil and does not need to be cleaned. The size of the ecological mat, the color of the geotextile, and the green plant seeds in the nutrient soil layer can all be customized according to needs to meet the requirements in different usage scenarios.

[0008] Further, the widths of the upper geogrid, the nutrient soil layer, and the lower geogrid are correspondingly equal; the edge width of the geocomposite fabric is greater than the width of the lower geogrid. The edge of the geocomposite fabric is turned upwards and successively wraps the edge of the lower geogrid and the edge of the nutrient soil layer, and then presses on the bottom of the upper geogrid; the edge width of the upper geotextile is greater than the width of the upper geogrid. The edge of the upper geotextile is turned downwards and successively wraps the edge of the upper geogrid and the edge of the geocomposite fabric, and then is sewn to the bottom of the lower layer.

[0009] By adopting the above technical solutions, the geocomposite fabric in the lower layer of the ecological composite mat is commonly known as two-layer geotextile and one-layer geomembrane. The outer layer of geotextile can effectively prevent the sharp foreign objects that may exist on the plane where the ecological mat is placed from damaging the product (the geotextile has excellent puncture resistance), thus causing functional damage; the inner layer of geotextile can ensure good compounding with the plastic grid; the middle geomembrane, under the protection of the inner and outer layers of geotextiles, can stably play the role of waterproofing, ensuring that the moisture in the ecological mat is not easy to lose, providing a strong guarantee for the normal growth of the plants in the ecological mat. This special structure of the ecological mat can eliminate the dependence of the ecological mat on the underlying soil. Whether it is placed on various soil-free foundation surfaces such as stones, concrete, steel, waterproof materials, or on harsh foundations such as landfills and chemical raw material landfills, the plants and flowers in the ecological mat can grow vigorously.

[0010] Further, the upper geotextile is connected to the upper geogrid through thermal compounding, adhesion or stitching processes; the geomembrane and the two layers of lower geotextiles are thermally compounded into a geocomposite fabric, and the geocomposite fabric is connected to the lower geogrid through an adhesion or thermal compounding process.

[0011] Further, it also includes longitudinal stitching lines and transverse stitching lines, and both the longitudinal stitching lines and the transverse stitching lines stitch and connect the upper layer, the middle layer and the lower layer.

[0012] Further, a plurality of longitudinal stitching lines and transverse stitching lines are evenly arranged.

[0013] By adopting the above technical solution, a plurality of longitudinal stitching lines and transverse stitching lines are arranged on the ecological composite mat. Through the longitudinal and transverse cross-distribution, the ecological mat is divided into a plurality of small squares, effectively reducing or preventing the random movement and accumulation of the nutrient soil in the ecological mat within the cushion layer, which is beneficial to meeting the balance of the nutrients required for the growth of plants in the ecological mat.

[0014] Further, a reinforcement component is arranged in the middle layer. The reinforcement component includes a bottom plate fixed to the top of the lower geogrid, a connecting column fixed to the top of the bottom plate, a top plate fixed to the top of the connecting column, and an L-shaped limiting plate fixed to the top of the top plate. There are four L-shaped limiting plates, and the four L-shaped limiting plates cooperate and are clamped with the cross area of the upper geogrid.

[0015] By adopting the above technical solution, to ensure the stability of the upper and lower geogrids during use, the staff needs to adjust the upper geogrid to a state corresponding to the position of the lower geogrid, and splice them through the reinforcement component. Subsequently, the staff needs to place the spliced double-layer geogrid on the lower geocomposite fabric, then set the middle layer (nutrient soil layer), and finally set the upper geotextile on the top of the upper geogrid, and connect the multi-layer structure of the ecological composite mat into one body by means of quilting connection. During use, the four L-shaped limiting plates in the same group of reinforcement components cooperate to ensure the stability of the two geogrids during use.

[0016] Further, there are four groups of the reinforcement components, which are distributed in a rectangular array at the four corners of the ecological composite mat.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. In this application, the nutrient soil layer is doped with seeds of flowers, grasses or other plants, and the nutrient soil is formulated according to the corresponding seeds. The upper geogrid and the upper geotextile cooperate, and the lower geogrid and the geocomposite cooperate to ensure the stability of the nutrient soil during use. Both the upper geotextile and the lower geotextile are excellent filtration and anti-filtration materials, having ideal water permeability and being able to prevent the loss of the nutrient soil in the ecological mat well, providing good conditions for the growth of the internal green plant seeds.

[0019] 2. The upper geogrid and the lower geogrid play a very good role as a framework, overcoming the defect that the ecological mat structure is unstable caused by the softness, easy deformation and wrinkling of the upper geotextile and the geocomposite. Quilting connection is a process of sewing the outer layer and the inner core of the textile, forming a simple and stable whole among the upper layer, the middle layer and the lower layer, providing a favorable guarantee for the greening and beautification functions of the ecological mat. All kinds of materials in the ecological mat, such as the upper geogrid, the upper geotextile, the nutrient soil layer, the lower geogrid and the geocomposite, are pollution-free environmental protection materials. For the ecological mat used for a long time, with the growth of the plants in the mat, especially the plants with larger root systems, it will integrate with the soil in the lower layer and does not need to be cleaned. The size of the ecological mat, the color of the geotextile and the green plant seeds in the nutrient soil layer can all be customized according to needs to meet the requirements in different usage scenarios.

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] As Figures 1-8 shown, an embodiment of the present application discloses a grid-protected modular ecological composite mat, which includes an upper layer 1, a middle layer 2, and a lower layer 3 arranged in sequence from top to bottom; the upper layer 1 includes an upper geogrid 11 and an upper geotextile 12 laminated on the top of the upper geogrid 11; the middle layer 2 is a nutrient soil layer mixed with green plant seeds; the lower layer 3 includes a lower geogrid 31 and a geocomposite fabric 32 laminated on the bottom of the lower geogrid 31, and the geocomposite fabric 32 is composed of a geomembrane 321 and lower geotextiles 322 laminated on the upper and lower surfaces of the geomembrane 321.

[0031] The widths of the upper geogrid 11, the nutrient soil layer, and the lower geogrid 31 are correspondingly equal; the edge width of the geocomposite fabric 32 is greater than the width of the lower geogrid 31. The edge of the geocomposite fabric 32 is turned up, and after wrapping the edge of the lower geogrid 31 and the edge of the nutrient soil layer in sequence, it is pressed against the bottom of the upper geogrid 11; the edge width of the upper geotextile 12 is greater than the width of the upper geogrid 11. The edge of the upper geotextile 12 is turned down, and after wrapping the edge of the upper geogrid 11 and the edge of the geocomposite fabric 32 in sequence, it is sutured to the bottom of the lower layer 3, ensuring the stability of the nutrient soil layer and reducing the probability of nutrient soil loss in the nutrient soil layer.

[0032] The nutrient soil layer is doped with seeds of flowers, grasses or other plants, and the nutrient soil is formulated according to the corresponding seeds. Both the upper geotextile 12 and the lower geotextile 322 are excellent filtration and anti-filtration materials, having ideal water permeability and being able to well prevent the loss of the nutrient soil in the ecological mat, providing good conditions for the growth of the internal green plant seeds. The upper geogrid 11 and the lower geogrid 31 play a very good role as a skeleton, overcoming the defect that the ecological mat structure is unstable caused by the softness, easy deformation and wrinkling of the upper geotextile 12 and the geocomposite fabric 32. The upper geotextile 12 is connected to the upper geogrid 11 through heat composite, adhesion or stitching process; the geomembrane 321 and the two layers of lower geotextiles 322 are heat-composited into a geocomposite fabric 32, and the geocomposite fabric 32 is connected to the lower geogrid 31 through adhesion or heat composite process. The ecological composite mat also includes a longitudinal stitching line 5 and a transverse stitching line 6. Both the longitudinal stitching line 5 and the transverse stitching line 6 stitch and connect the upper layer 1, the middle layer 2 and the lower layer 3, making the upper layer 1, the middle layer 2 and the lower layer 3 form a simple and stable whole, providing a favorable guarantee for the greening and beautification functions of the ecological mat. All kinds of materials in the ecological mat are pollution-free environmental protection materials. For the ecological mat used for a long time, with the growth of the plants in the mat, especially the plants with larger root systems, it will integrate with the soil and does not need to be cleaned up. The size of the ecological mat, the color of the geotextile, and the green plant seeds in the nutrient soil layer can all be customized according to needs to meet the requirements in different usage scenarios.

[0033] There are multiple longitudinal stitching lines 5 and transverse stitching lines 6 evenly arranged. Through the vertical and horizontal cross-distribution, the ecological mat is divided into multiple small squares, effectively reducing or preventing the random movement and accumulation of the nutrient soil in the ecological mat in the cushion layer, which is beneficial to meeting the balance of the nutrients required for the growth of the plants in the ecological mat.

[0034] A reinforcement component 7 is arranged in the middle layer 2. The reinforcement component 7 includes a bottom plate 71 fixed to the top of the lower geogrid, a connecting column 72 fixed to the top of the bottom plate 71, a top plate 73 fixed to the top of the connecting column 72, and an L-shaped limiting plate 74 fixed to the top of the top plate 73. There are four L-shaped limiting plates 74, and the four L-shaped limiting plates 74 cooperate and are clamped with the cross area of the upper geogrid 11. There are four groups of reinforcement components 7 and they are distributed in a rectangular array at the four corners of the ecological composite mat. To ensure the stability of the upper geogrid 11 and the lower geogrid 31 during use, the staff needs to adjust the upper geogrid 11 to a state corresponding to the position of the lower geogrid 31, and carry out such as Figure 6For the splicing shown, subsequently, the staff needs to place the spliced double-layer geogrid on the lower geocomposite fabric 32, then set the middle layer 2 (nutrient soil layer), and finally set the upper geotextile 12 on the top of the upper geogrid 2, and connect the multi-layer structure of the ecological composite mat into one by means of quilting connection. During use, the four L-shaped limit plates 74 in the same group of reinforcement components 7 cooperate to ensure the stability of the two-layer geogrid during use.

[0035] In this embodiment, the working principle of a grid-protected modular ecological composite mat is as follows: Geotextile is a filtering and anti-filtering material with excellent performance. It has ideal water permeability and can well prevent the loss of nutrient soil in the ecological mat, providing good conditions for the growth of internal green plant seeds. The upper geogrid 11 and the lower geogrid 31 play a good role as a framework, overcoming the defect that the ecological mat structure is unstable due to the softness, easy deformation and wrinkling of the upper geotextile 12 and the geocomposite fabric 32. Quilting connection is a process of sewing the outer layer and the inner core of a textile, forming a simple and stable whole among the upper layer 1, the middle layer 2 and the lower layer 3, providing a favorable guarantee for the greening and beautifying functions of the ecological mat.

[0036] The function of the two-layer fabric and one-membrane structure in the lower layer: The outer geotextile can effectively prevent the sharp foreign objects that may exist on the placement plane of the ecological mat from damaging the product (the geotextile has excellent puncture resistance), thus causing functional damage; the inner geotextile can ensure good composite with the plastic grid; the middle geomembrane can stably play a waterproof role under the protection of the inner and outer layers of geotextiles, and can ensure that the moisture in the ecological mat is not easy to lose.

[0037] The overall wrapping treatment of the edge of the ecological mat: It also has a good effect of preventing the loss of moisture from the four sides of the ecological mat (the excess moisture can only flow out or evaporate from the upper geotextile of the ecological mat; due to the loose and multi-directional random distribution of the geotextile fibers and the multi-directional filling and repair of the fibers after needling, the proportion of the moisture lost through the needle holes formed by quilting is very small).

[0038] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and retouches made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
