Description

Technical Field

[0001] The utility model relates to the technical field of lawn modules, in particular to a lawn module which is convenient for drainage. Background Art

[0002] The lawn module is provided with a frame, a geotextile, a soil layer and a natural lawn from bottom to top, wherein a filling pad is provided inside the frame, and a plurality of vertical drainage holes are provided on the filling pad, and side drainage holes leading to the outside are provided on the side wall of the frame. In heavy rainy weather, rainwater flows into and accumulates in the vertical drainage holes, and the accumulated water in the vertical drainage holes at the edge of the filling pad can flow out along the side drainage holes of the frame, while the accumulated water in the vertical drainage holes in the middle of the filling pad cannot be discharged in time, which is easy to cause local water accumulation. Utility Model Content

[0003] The utility model provides a lawn module which is convenient for draining water and can avoid local water accumulation in the lawn module.

[0004] To achieve the above-mentioned purpose, the utility model provides a lawn module that is easy to drain water. A frame and a natural lawn are arranged in sequence from bottom to top. A filling pad is arranged in the frame. The filling pad has a plurality of vertical drainage holes that penetrate up and down. The filling pad has an upper and a lower layer. The upper layer has a plurality of vertical drainage upper holes that penetrate up and down, and the lower layer has a plurality of vertical drainage lower holes that penetrate up and down. One upper hole is connected to a plurality of lower holes, and the sum of the cross-sectional areas of the plurality of lower holes is greater than the cross-sectional area of ​​the one upper hole. At least one of the lower holes is also connected to at least one other upper hole.

[0005] Furthermore, a hole wall of at least one upper through hole is provided with a notch leading to at least one adjacent upper through hole.

[0006] Furthermore, at least one upper through hole has a plurality of notches, which respectively lead to different adjacent upper through holes.

[0007] Furthermore, the notch is formed at the top of the wall of the upper through hole.

[0008] Furthermore, the upper layer of the filling pad is a grass grid, and the lower layer is a fiberglass grille; or the upper layer is a fiberglass grille, and the lower layer is a grass grid; or both the upper and lower layers are grass grids or fiberglass grilles.

[0009] Furthermore, the frame includes a plurality of grids arranged transversely, and each grid is provided with the filling pad.

[0010] Furthermore, a support portion is extended from the bottom of the frame toward the inside of the frame, and the filling pad is supported on the support portion.

[0011] Furthermore, at least one side drainage through hole leading to an adjacent frame or the outside is opened on the side wall of the frame.

[0012] Furthermore, geotextile and soil layers are arranged between the frame and the soil lawn from bottom to top.

[0013] Further, the soil layer is a mixture of sand, peat soil and fiber mesh.

[0014] The filling pad has an upper and a lower layer. Rainwater passes through the upper layer into the lower layer. Because one of the upper through holes is connected to multiple lower through holes, the sum of the cross-sectional areas of the multiple lower through holes is larger than the cross-sectional area of ​​the one upper through hole. Therefore, even if the rainwater is locally accumulated in the upper through hole due to uneven distribution, it can be dispersed by the multiple lower through holes to avoid local water accumulation in the drainage through hole. At least one of the lower through holes is also connected to another adjacent upper through hole, that is, the lower through hole can drain water for the two adjacent upper through holes at the same time, with high utilization rate. Air flow is also achieved between the two adjacent upper through holes through the lower through hole, which is beneficial to the growth of grass roots of natural lawns.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with specific implementation methods.

[0024] like Figure 1In the lawn module shown, the frame 1 includes nine grids 11 arranged horizontally and vertically, and the nine grids 11 are separated by two parallel beams 6 horizontally and vertically, and each beam 6 is provided with a slot 61 for inserting the forklift arm. A support portion 7 extends from the bottom of each grid 11 toward the inside of the grid 11, and a filling pad 2 is supported on the support portion 7 in each grid 11, and the filling pad 2 is provided with a plurality of vertical drainage holes that penetrate from top to bottom. Three side drainage holes 8 leading to adjacent grids 11 or the outside are provided on the side wall of each grid 11. A geotextile 3 is laid on the top of the frame 11, and the geotextile 3 is bonded to the top of the frame 11. A soil layer 4 is provided above the geotextile 3, and the soil layer 4 is a mixture of sand, peat soil and fiber mesh. The natural lawn 5 is laid on the soil layer 4, and the soil layer 4 should not be too thick, so as to prevent the grass roots of the natural lawn 5 from taking root only to the upper surface of the soil layer 4 but not to the bottom of the soil layer 4, resulting in insufficient adhesion.

[0025] like Figure 2 , Figure 3 As shown, the filling pad 2 has an upper layer 21 and a lower layer 22. The upper layer 21 has a plurality of vertical drainage holes 211 and 212 extending vertically, and the lower layer 22 has a plurality of vertical drainage holes 221, 222, 223, and 224 extending vertically. The upper layer 21 is a grass grid, such as Figure 4 The through holes 211 and 212 on the grass grid are in the shape of hollow hexagons. The lower layer 22 is a glass fiber reinforced plastic grid. Figure 5 The through holes 221, 222, 223, and 224 under the glass fiber reinforced plastic grille are shaped as hollow rectangles. In heavy rain, rainwater passes through the upper layer 21 and enters the lower layer 22. Figure 3 , this embodiment is designed as an upper through hole 211 (see Figure 4 ) connects the four lower through holes 221, 222, 223, 224 (see Figure 5 ), the sum of the cross-sectional areas of the four lower through holes 221, 222, 223, 224 is greater than the cross-sectional area of ​​the upper through hole 211, so that even if rainwater is partially accumulated in the upper through hole 211 due to uneven distribution, it can be dispersed by the four lower through holes 221, 222, 223, 224 to avoid local water accumulation; two of the lower through holes 222, 223 are also connected to another upper through hole 212, that is, the lower through hole 222 can simultaneously drain water for the two upper through holes 211, 212, with high utilization rate, and air flow is also achieved between the two upper through holes 211, 212 through the lower through hole 222, which is beneficial to the growth of the grass roots of natural lawns. Figure 6 , Figure 7As shown, in order to deal with the situation of water accumulation in the upper through holes 211 and 212, six notches 9 are respectively opened on the six sides of the hexagon at the top of the hole wall of the grass grid of the upper layer 21, leading to different adjacent upper through holes respectively. Even if water accumulates in the upper through hole 211, the accumulated water can be diverted laterally to the six adjacent upper through holes through the notches 9. The notches 9 also allow air to flow between two adjacent upper through holes 211 and 212, which is beneficial to the growth of the grass roots of the natural lawn 5.

[0026] The grass grids on the upper layer 21 and the glass grids on the lower layer 22 can be placed interchangeably, that is, the glass grids are placed on the upper layer 21 and the grass grids are placed on the lower layer 22, or both the upper layer 21 and the lower layer 22 are grass grids or glass fiber reinforced plastic grids.

[0027] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
