Description
Technical Field
[0001] The utility model relates to the technical field of greening auxiliary equipment, in particular to an anti-reverse seepage water grass planting grid. Background Art
[0002] As people become more environmentally conscious, they are increasingly concerned about the greening of their surroundings. Planting turf is a common method for greening the environment. However, if lawns are planted directly in places like parking lots and fire lanes, vehicles parked or passing by will press directly on the grass, causing it to wither and die. This also compacts the soil, damaging its structure and making it unsuitable for growing grass.
[0003] Therefore, where hardened greening is needed, grass grids are used instead of paving. Grass grids are a grid-like structure with multiple cylindrical spaces filled with soil for growing grass. Because of their height and structural strength, grass grids protect the soil and grass roots from being damaged by vehicles, thus preserving the lawn.
[0004] Currently, the bottom of existing grass grids is a hollow structure, which is not only water-permeable but also leaks soil. In heavy rain, the soil in the grass grids is easily washed away by rain, carrying away grass seeds in the soil or exposing grass roots, affecting grass growth and thus affecting the greening effect.
[0005] Furthermore, if the foundation beneath the grass grids is poorly permeable, water can easily accumulate between the grids and the foundation. When people or vehicles press on the grids, the grids bend downward, and the accumulated water can seep back into the grids. During this process, the accumulated water can carry away soil from the grids, affecting the effectiveness of the grass planting. The accumulated water can even seep back above the grids, splashing onto shoes or pants when people step on them. Utility Model Content
[0006] In order to solve the technical problems existing in the above background technology, the utility model provides an anti-reverse seepage water grass grid.
[0007] The technical solution of this utility model is as follows:
[0008] A grass-planting grid for preventing reverse osmosis water is laid on a foundation and is used for planting grass. The grid comprises a plate body, a plurality of grass-planting holes distributed in a honeycomb pattern on the plate surface for storing soil for planting grass. A plurality of connecting ribs are provided at the bottom ends of the grass-planting holes. The connecting ribs intersect with each other and extend radially along the grass-planting holes at both ends and are connected to the side walls of the grass-planting holes to enhance the structural strength of the grass-planting holes and thereby enhance the structural strength of the entire plate body.
[0009] A fine mesh cloth is connected to the lower surface of the slab to remove water and retain soil. The fine mesh cloth can seep water, but soil cannot leak out from under the fine mesh cloth. The fine mesh cloth covers the lower end of all grass planting holes and is located below the connecting ribs.
[0010] The shapes of the left and right sides of the board body are adapted to each other, and the shapes of the front and rear sides are adapted to each other, so that multiple boards can be seamlessly spliced together.
[0011] In order to better retain the soil, the fine mesh cloth is sealed and connected to the bottom surface of the side wall of the grass planting hole, that is, the fine mesh cloth seals the bottom of each grass planting hole one by one, so that the soil remains intact in the grass planting hole. At the same time, it can also strengthen the connection strength between the fine mesh cloth and the plate body to prevent the fine mesh cloth from falling off or being damaged.
[0012] Preferably, the shape of the fine mesh cloth is the same as that of the bottom surface of the board, or at least not smaller than the shape of the bottom surface of the board, so that when multiple boards are spliced together, multiple fine mesh cloths can be completely sealed between the board and the foundation.
[0013] In this application, the fine mesh cloth is a geotextile.
[0014] The fine mesh cloth can be fixed to the bottom of the board through a hot melt process. Of course, it can also be attached to the bottom of the board through adhesive, but after long-term use, the adhesive will gradually age and lose its stickiness, making it impossible to fix the fine mesh cloth to the board well.
[0015] Furthermore, the grass planting holes are regular hexagonal holes, which makes the structure of the grass planting holes more stable, easier to form a regular arrangement, and easier to achieve the effect of sealing and splicing multiple plates.
[0016] Three connecting ribs are provided at the bottom of the grass planting hole, and the two ends of the connecting ribs are connected to the relative corner positions of the side walls of the grass planting hole to enhance the deformation resistance of the grass planting hole.
[0017] In addition, in order to protect the grass from being crushed, the present invention provides a notch on the upper side wall of the grass planting hole. When a person or a vehicle presses on the grass planting grid, the grass can be bent into the notch to prevent its stems and leaves from being crushed.
[0018] When multiple panels are spliced together, in order to ensure that the multiple panels are stably spliced and connected into a whole, a slot is provided on one side of the panel and an insert block that matches the slot is provided on the opposite side. The multiple panels are spliced together through the slot and the insert block.
[0019] The board is made of modified high molecular weight HDPE material.
[0020] The utility model provides an anti-reverse seepage grass grid. Through the provision of a fine-mesh cloth, water can seep in and retain soil, preventing soil loss in the grass planting holes and ensuring a stable foundation for grass growth. At the same time, it can also prevent water accumulated below the grass grid from seeping back into or above the grass grid, destroying the grass growing soil and even soiling people's shoes or pants.

[0027] like Figures 1 to 3 As shown, an embodiment of the utility model provides an anti-reverse seepage water grass-planting grid, which is laid on a foundation and used for planting grass.
[0028] The grass grid includes a plate body 1, which is preferably made of modified high molecular weight HDPE material, which has high supporting strength and excellent toughness.
[0029] The plate body 1 is provided with a plurality of grass planting holes 2 arranged in a honeycomb pattern. These holes are used to store soil for grass planting. Connecting ribs 3 are located at the bottom ends of the holes 2. These ribs intersect with each other and extend radially along the holes 2 at both ends, connecting to the sidewalls of the holes 2. This strengthens the structural strength of the holes 2, and thus the entire plate body 1.
[0030] A fine mesh cloth 4 is connected to the lower surface of the plate body 1 and is located below the connecting ribs 3. The fine mesh cloth 4 can seep water but not leak soil, and plays the role of removing water and retaining soil.
[0031] In this embodiment, the fine mesh cloth 4 is a geotextile, which is fixed to the bottom surface of the plate body 1 by a hot-melt process.
[0032] Of course, the fine mesh cloth 4 can also be pasted on the bottom surface of the plate body 1 by an adhesive, but after long-term use, the adhesive will gradually age and lose its viscosity, making it impossible to fix the fine mesh cloth 4 to the plate body 1, resulting in it falling off and failing to retain soil.
[0033] In addition, in order to better retain the soil, the fine mesh cloth 4 is sealed to the bottom surface of the side wall of the grass planting hole 2. That is, the fine mesh cloth 4 seals the bottom of each grass planting hole 2 one by one, so that the soil remains completely in the grass planting hole 2 where it is located, and will not leak down or move to other grass planting holes 2. At the same time, it can also strengthen the connection strength between the fine mesh cloth 4 and the plate body 1, preventing the fine mesh cloth 4 from falling off or being damaged.
[0034] Furthermore, the shape of the fine mesh cloth 4 is at least not smaller than the bottom shape of the board 1, and preferably is the same as the bottom shape of the board 1, so that when multiple boards 1 are spliced together, multiple fine mesh cloths 4 can be completely sealed between the board 1 and the foundation.
[0035] like Figure 3 As shown, the grass planting holes 2 in this embodiment are regular hexagonal holes, which makes the structure of the grass planting holes 2 more stable, easier to form a regular arrangement, and easier to achieve the effect of sealing and splicing multiple plates 1.
[0036] The plate body 1 is a grid-like plate formed by multiple regular hexagonal holes arranged in a honeycomb pattern. The outer side walls of the outermost regular hexagonal holes form the outer surface of the plate body 1. The shapes of the left and right sides of the plate body 1 are adapted to each other, and the shapes of the front and back sides are adapted to each other, so that multiple plates 1 can be seamlessly spliced together.
[0037] In this embodiment, the side walls of each grass planting hole 2 and the connecting ribs 3 are integrally formed.
[0038] To achieve stable splicing between multiple panels 1 and connect them into a whole, a slot 5 is provided on one side of the panel 1, and an insert 6 is provided on the opposite side thereof to fit the slot 5. The multiple panels 1 are spliced together by plugging and fitting the slots 5 and inserts 6. The number of slots 5 and inserts 6 can be set accordingly according to the size of the panel 1.
[0039] In this embodiment, a group of slots 5 and insert blocks 6 are provided on the left and right sides and the front and rear sides of the board body 1, so that the board body 1 can be spliced horizontally and vertically in a horizontal plane.
[0040] Furthermore, there are three connecting ribs 3 at the bottom end of the grass planting hole 2, which cross each other on the center line of the grass planting hole 2. The two ends of the connecting ribs 3 are connected to the relative corner positions of the side walls of the grass planting hole 2, that is, the three connecting ribs 3 are evenly distributed laterally with the center line of the grass planting hole 2 as the axis to enhance the deformation resistance of the grass planting hole 2.
[0041] In addition, if Figure 1 As shown, in order to protect the grass and avoid it being crushed, a notch 7 is provided on the upper part of the side wall of the grass-planting hole 2. When a person or a vehicle presses on the grass-planting grid, the grass can be bent into the notch 7 to avoid its stems and leaves being crushed.
[0042] The utility model provides an anti-reverse seepage grass grid. The fine-mesh cloth 4 is provided to allow water to seep in and retain soil, thereby preventing soil loss in the grass planting holes 2 and ensuring a stable foundation for grass growth. At the same time, it can also prevent water accumulated below the grass grid from seeping back into or above the grass grid, destroying the grass growing soil and even soiling people's shoes or pants.
