DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment 1, the present invention provides as follows Figure 1-7 A football field lawn is shown, which is composed of a grass layer 1, a shock-absorbing layer 2, a concrete layer 3, a crushed stone layer 4 and a plain soil layer 5 from top to bottom, and a drainage mechanism is provided in the crushed stone layer 4; Specifically, the grass layer 1 is composed of a rubber base 101 and artificial grass 103 from bottom to top, a plurality of artificial grasses 103 are laid on the top of the rubber base 101 in an array, and a plurality of water seepage holes 102 are vertically opened in the middle of the rubber base 101 and between the gaps of the plurality of artificial grasses 103 .

[0027] Furthermore, the side cross-section of the water seepage hole 102 is a trapezoid, and the hole diameter at the top of the water seepage hole 102 is 1.5-2 times the hole diameter at the bottom; The laying height of the artificial grass 103 on the top of the rubber base 101 is 40-50 mm, the laying needle count of the artificial grass 103 is 11000-12000, and the laying weight of the artificial grass 103 is 7000-7500 pounds.

[0028] It should be noted that the water seepage hole 102 is provided at the rubber seat 101 so that when the lawn is raining or watered, the accumulated water falling on the artificial grass 103 and the top of the rubber seat 101 can fall and be discharged through the water seepage hole 102, and the water seepage hole 102 is provided in a trapezoidal cross-section with a larger upper portion and a smaller lower portion, so as to facilitate the rapid accumulation and fall of the accumulated water on the top of the rubber seat 101; The rubber base 101 is made of polyester material. Polyester has high strength and toughness, can remain stable within a certain temperature range, is suitable for thermoforming, and has good resistance to a variety of chemicals (such as acids and alkalis). Therefore, polyester material is used as the base part of the grass layer 1, and the artificial grass 103 can be made of polypropylene or nylon. The artificial grass 103 prepared in this way can have better durability.

[0029] Specifically, the shock absorbing layer 2 includes a resin shock absorbing pad 201 , a plurality of water guide grooves 202 are provided at the top of the resin shock absorbing pad 201 , a plurality of water guide holes 203 are provided at the bottom of the plurality of water guide grooves 202 , and a plurality of reinforcing strips 204 are provided on the top inner walls of the plurality of water guide grooves 202 .

[0030] It should be noted that the main body of the shock-absorbing layer 2 adopts the resin shock-absorbing pad 201 to provide better support and cushioning effects, and to achieve a better user experience with the full artificial grass 103. At the same time, the water guide groove 202 is opened on the top of the resin shock-absorbing pad 201 to reduce the use of materials, and at the same time, the water flow seeping from the water seepage hole 102 can be guided and discharged. In order to enable the water guide groove 202 to better guide and drain water, the middle part of the water guide groove 202 is higher than the side, and the water guide hole 203 is used to quickly discharge the water flow; At the same time, after the resin shock-absorbing pad 201 is opened with the water guide groove 202, the deformation space in the middle area is increased, so that it can better absorb shock and buffer when being stepped on. At the same time, in order to strengthen the structural strength of the resin shock-absorbing pad 201, a reinforcement strip 204 is added. The reinforcement strip 204 is used to stabilize the shape of the water guide groove 202 to prevent it from being unable to return to its original shape after being deformed when being stepped on.

[0031] Specifically, a plurality of drainage holes 301 are provided in the middle of the concrete layer 3 along the vertical direction. The side cross-section of the drainage hole 301 is trapezoidal, and the bottom hole diameter of the drainage hole 301 is 2.5-3 times the top hole diameter.

[0032] It should be noted that the drainage holes 301 of the concrete layer 3 are designed to cooperate with the water guide holes 203 to facilitate the rapid fall of accumulated water, so that the accumulated water in the middle area of ​​the lawn can be quickly removed.

[0033] The drainage structure includes multiple sets of drainage pipes, which are arranged in the horizontal direction and interspersed between the gravel layers 4. Multiple sets of water seepage parts are arranged on the top of the drainage pipes, and the multiple sets of water seepage parts are used to drain water into the drainage pipes at multiple points; Specifically, the gravel layer 4 includes a cement frame 401 , the drainage pipeline is inserted and connected in the cement frame 401 , and gravel particles 402 are laid in the cement frame 401 and around the drainage pipeline, and the gravel particles 402 are used to shield the water seepage part.

[0034] It should be noted that, first, a cement frame 401 is established to limit the area and shape of the crushed stone layer 4. With such a structural setting, after the crushed stone particles 402 are laid in the cement frame 401, the restraint of the crushed stone particles 402 can be better achieved, thereby ensuring the stability of the structure of the crushed stone layer 4, and further protecting the drainage pipes interspersed in the cement frame 401, thereby preventing the crushed stone particles 402 from rolling after being stepped on and causing scratches on the drainage pipes. The crushed stone particles 402 can be crushed stones or gravel, and the purpose is to improve drainage.

[0035] Furthermore, the drainage pipeline includes a high-density polyethylene pipe 6, which is inserted and connected in the cement frame 401, and both ends of the high-density polyethylene pipe 6 are connected to both sides of the cement frame 401. A plurality of water inlets are provided on the top of the high-density polyethylene pipe 6, and the seepage part includes a seepage filter plate 601, which is filled at the water inlet, and a plurality of filter holes 602 are provided on the top of the seepage filter plate 601.

[0036] It should be noted that, by setting up multiple high-density polyethylene pipes 6, the accumulated water that seeps can be discharged through multiple channels. At the same time, a group of seepage filter plates 601 are set at the top of each high-density polyethylene pipe 6. Such a setting enables the high-density polyethylene pipe 6 to have multiple water inlet channels for water conduction and drainage.

[0037] Filling particles are laid in the grass layer 1 , and the filling particles are used for trampling and conductive protection of the grass layer 1 . The filling particles are filled to the top of the rubber seat 101 .

[0038] Specifically, the filling particles include: Silica sand particles 7, which are laid on the top of the rubber base 101 and are located between the plurality of artificial grasses 103; Copper particles 8 are laid on the top of the adhesive base 101 and are located between the silica sand particles 7 .

[0039] It should be noted that the silica sand particles 7 are used because they have the following functions, including drainage. The particle structure and porosity of silica sand make it have good drainage performance, which can effectively prevent water accumulation and keep the lawn dry; stability. The silica sand particles are hard and can provide good support to help the grass stay upright and extend the service life of the lawn; wear resistance. Silica sand has high wear resistance and is suitable for use in high-intensity sports venues and can withstand frequent trampling and friction; non-toxicity. Silica sand is a natural material, does not contain harmful chemicals, is safe and environmentally friendly, and is suitable for use in various occasions; The use of copper particles 8 has the following functions, including antibacterial properties. Copper has natural antibacterial properties and can inhibit the growth of certain bacteria and fungi, which helps to reduce the occurrence of diseases on the lawn; wear resistance. Copper particles 8 usually have good wear resistance and can withstand the mechanical force when stepped on; conductivity. The conductivity of the top surface of the lawn is increased by mixing copper particles 8, which reduces the generation of static electricity and increases the service life of the lawn.

The soil is turned over and crushed and then mixed with sand to improve the soil and increase its air permeability and drainage. After that, it is compacted with a compactor to ensure that the raw soil layer 5 is laid flat.

[0042] S3, laying the gravel layer 4 and the drainage pipeline, first use cement to build a frame on the surface of the plain soil layer 5, then lay a layer of gravel at the bottom of the frame, set the drainage pipeline on the top of the gravel and pass both ends of the drainage pipeline through the frame, set the seepage part on the top of the drainage pipeline, lay gravel again, fill the frame and level it; It should be noted that when constructing the gravel layer 4, first, cement is used to pile up a cement frame 401 to form a bearing trough structure, and then through holes are reserved on both sides of the cement frame 401. After that, the bottom layer of the cement frame 401 is paved with gravel particles 402, and then the high-density polyethylene pipe 6 is buried, and the two ends of the high-density polyethylene pipe 6 are passed through the through holes reserved in the cement frame 401, and the water inlet at the top of the high-density polyethylene pipe 6 is covered with a seepage filter plate 601, and then the gravel particles 402 are laid, and the gravel particles 402 are compacted and leveled.

[0043] S4, laying the concrete layer 3, firstly build a concrete formwork according to the designed area and requirements, then pour the concrete, and after pouring, use a vibrator to vibrate and level it; It should be noted that when laying the concrete layer 3, foam is used to make the shape of the drainage hole 301 in the concrete template, and then after the concrete is injected and vibrated and leveled, the concrete layer 3 is cured. At this time, the concrete layer 3 needs to be watered and cured. After six to eight days of curing, the foam blocks are crushed and taken out to form the drainage hole 301 structure in the concrete layer 3.

[0044] S5, laying the shock-absorbing layer 2, first cutting the resin block according to the area to be laid, then opening a slot on the top of the resin block, and then after the concrete layer 3 is cured, using an adhesive to splice and stick the resin block on the top of the concrete layer 3; It should be noted that the shock-absorbing layer 2 is connected to the top of the concrete layer 3 in the form of block splicing. When connecting the shock-absorbing layer 2, glue is first brushed on the surface of the concrete layer 3, and then the water guide hole 203 is aligned with the drainage hole 301 as much as possible, and then the shock-absorbing layer 2 is completely laid.

[0045] S6, laying the grass layer 1, gluing and laying the processed grass layer 1 along the top of the shock-absorbing layer 2, and then laying filling particles on the top of the grass layer 1, and brushing the filling particles flat; It should be noted that the rubber seat 101 of the grass layer 1 is also fixed to the top of the shock-absorbing layer 2 by gluing, and the seepage hole 102 is arranged above the water guide groove 202 as much as possible, so as to facilitate water conduction and drainage. After the grass layer 1 is laid, the grass layer 1 is fixed to the shock-absorbing layer 2 with lawn nails. The distance between the nails is generally 20-30 cm to ensure that the grass layer 1 is not easy to move. Finally, the copper particles 8 are mixed with the silica sand particles 7 and laid on the top of the rubber seat 101. The filling material is brushed flat with a broom to make it evenly distributed, thereby ensuring the appearance and performance of the lawn, helping the lawn to stay upright and increase stability.
