Description

Technical Field

[0001] This invention relates to a method for repairing lawns, specifically a method for repairing natural grass sports fields by patching and restoring the grass. Background Technology

[0002] Natural grass sports fields include football fields, baseball fields, softball fields, rugby fields, tennis courts, and cricket fields. Due to the unique characteristics of natural grass, these fields often encounter the problem of not being able to be used immediately after installation. Furthermore, after the fields are put into use, high-frequency use can lead to the withering and bald patches of grass in highly competitive areas, requiring replanting and immediate use. Currently, methods such as sowing grass seeds, planting grass stems, laying sod blocks, laying sod rolls, and laying sod mats cannot solve the following shortcomings:

[0003] 1. The lawn cannot be used immediately after it is laid;

[0004] 2. The site is not flat;

[0005] 3. The surface of the site is loose. Summary of the Invention

[0006] The purpose of this invention is to provide a method for repairing natural grass sports fields using grass bricks, so that the sports field can be put into use immediately after the grass repair is completed using this method.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] A method for repairing and restoring natural grass sports fields using lawn pavers includes the following steps:

[0009] Step S1: Delineate the repair and patching area: On the natural grass sports field, measure the area that needs to be repaired and patched to determine the location and area of ​​the repair and patching, and delineate the shape of the repair and patching area. In order to ensure the neatness and aesthetics of the patching, the shape of the repair and patching area is rectangular or square.

[0010] Step S2: Cleaning and trimming the repaired area: Use a turf cutter to clean the repaired area, keeping the cleaning depth consistent with the thickness of the turf bricks. Trim the edges of the repaired area neatly using a string line. Use a scraper to manually level the area, matching the thickness of the turf bricks. Some of the collected fine sand can be left in the area for adjusting the flatness of the turf bed when transplanting turf bricks. The remaining fine sand and grass stems are sorted and piled at the edge of the site for replanting after the turf bricks in the preparation area are removed.

[0011] Step S3, Replanting Lawn Pads: Remove the lawn paver molds from the prepared grass area, cut the connecting parts between the lawn pavers to separate them completely, and use a cart to transfer the lawn pavers to the repair and replanting area. Replant the lawn pavers into the repair and replanting area, making sure the lawn pavers are joined end to end to cover the entire repair and replanting area. During the replanting process, adjust the height of the lawn pavers so that the height of the repair and replanting area is consistent with the height of the surrounding area.

[0012] Step S4, Cover with sand and water thoroughly: After the lawn bricks are replanted, cover the surface of the lawn bricks in the repaired area with a thin layer of sand, use a scraper to smooth it, and then water it. During the watering process, wash the sand on the grass surface of the lawn bricks to the bottom. After the lawn bricks are thoroughly watered, use a lawnmower with rollers to roll them to make them more compact.

[0013] Step S5, Maintenance: Newly replanted lawn cannot obtain moisture from the ground, so watering of the area should be strengthened to ensure the water supply for the lawn pavers during the rooting period; use a lawnmower with rollers regularly to roll the lawn to accelerate the rooting of the lawn pavers in the replanted area.

[0014] Furthermore, in step S1, the length and width of the repaired grass area must be multiples of 0.5m to match the size of the lawn bricks.

[0015] Furthermore, in step S3, the specific method for adjusting the height of the lawn bricks is as follows: using the dimensions of a straightedge or the height of a string line as a reference, the height of the lawn bricks in the repair and patching area is adjusted by increasing or decreasing the amount of sand at the bottom of the repair and patching area.

[0016] Furthermore, in step S2, the grass stem density of the lawn brick is 2-3 blades / square centimeter, the grass height of the lawn brick is no more than 2.5 centimeters, the surface hardness of the lawn brick is 70-90, and the water penetration rate of the lawn brick is greater than 0.6 mm / min.

[0017] Furthermore, in step S2, the thickness of the lawn brick is 5cm, and the length and width of the lawn brick are 50cm*50cm.

[0018] Furthermore, the specific method for preparing lawn bricks in the grass preparation area is as follows:

[0019] Step 1: Delineate the redevelopment area in the grass preparation area: Delineate the redevelopment area in the grass preparation area and mark it. Lay a layer of tarpaulin around the site in a place that does not affect the transportation of materials, for placing materials to be recycled during the redevelopment process.

[0020] Step 2, Remove the turf: Use a turf cutter to remove the turf from the prepared area and place the removed turf on the pre-laid tarpaulin.

[0021] Step 3, Leveling the slab bed: The river sand at the base of the grass removal location is screened and recycled. The fine sand is placed in the designated location, while the coarse sand is backfilled into the slab bed and manually leveled. Then, the slab bed is leveled and compacted using rollers or a rammer to ensure that the construction machinery such as loaders, forklifts, and sand covering machines can move freely.

[0022] Step 4: Laying the film: Lay the film on the prepared lawn bed to prevent the lawn roots from growing downwards and to allow the roots to clump together above the film;

[0023] Step 5: Laying the lawn paver mold: The lawn paver mold is a square grid. Lay the square grid on the film laid in step 4. Lay a nylon net inside the square grid. The nylon net serves to reinforce and support the lawn paver, so that it will not easily fall apart when it is removed later. After the lawn paver is laid on the site, the lawn roots can continue to grow through the nylon net. Lay a layer of fine sand on the nylon net inside the square grid.

[0024] Step 6: Lay a nylon net: Lay another layer of nylon net on the fine sand to enhance the tensile strength of the root layer, strengthen the stability of the turf bed, and protect the main roots and stolons of the lawn.

[0025] Step 7, Planting grass stems: Spread a layer of fine sand on the newly laid nylon net, water it to settle it, and then manually scrape and compact it. Plant grass stems on the fine sand. After planting the grass stems, spread a layer of fine sand evenly and compact it to keep the grass stems warm and moist, and improve the survival rate of the grass stems.

[0026] Step 8: Cover with non-woven fabric: Cover with non-woven fabric and secure it with bamboo skewers at the edges and seams. The purpose of covering with non-woven fabric is to keep warm and moist, and to ensure the survival rate of the grass stems.

[0027] Step 9: Perform routine maintenance until the lawn is fully established.

[0028] Furthermore, in step ⑤, the square grid has a length, width, and height of 100cm*100cm*5cm and a thickness of 1cm. The square grid is divided into four smaller squares of 50cm*50cm by a partition. Both the square grid and the partition are made of plastic.

[0029] Furthermore, in step ②, the thickness of the turf removed is 2cm.

[0030] Furthermore, in step ③, the mesh size of the sieve is 4mm; in steps ⑤ and ⑥, the mesh size of the nylon mesh is both greater than 1mm and less than 2mm.

[0031] Furthermore, in step ⑤, the thickness of the fine sand is 2cm; in step ⑦, the thickness of the fine sand spread on the newly laid nylon net is 2cm, and the thickness of the fine sand spread after the grass stems are planted is 1cm.

[0032] The beneficial effects of this invention are as follows:

[0033] This invention utilizes turf bricks to repair and restore natural turf sports fields. After construction, the repaired sports field features excellent flatness and a dense surface, allowing for immediate use. Furthermore, in this invention, the turf bricks have a turf stem density of 2-3 blades / cm², a grass height of no more than 2.5cm, a surface hardness of 70-90, and a water penetration rate greater than 0.6mm / min. These technical parameters are consistent with or close to the parameters of the turf when the sports field is put into use, thus enabling the turf bricks to integrate seamlessly with the surrounding turf.

[0034] This invention also provides a specific method for preparing lawn bricks in a grass preparation area. Lawn bricks prepared by this method have strong tensile strength in the root layer, good integrity, and are not easily loosened. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0040] like Figure 1As shown, a method for repairing and restoring natural grass sports fields using lawn pavers includes the following steps:

[0041] Step S1: Delineate the repair and patching area: On the natural grass sports field, measure the area that needs to be repaired and patched to determine the location and area of ​​the repair and patching, and delineate the shape of the repair and patching area. In order to ensure the neatness and aesthetics of the patching, the shape of the repair and patching area should be rectangular or square, and the length and width of the repair and patching area should be multiples of 0.5m to fit the size of the grass bricks.

[0042] Step S2: Cleaning and trimming the repaired area: Use a turf cutter to clean the repaired area, ensuring the cleaning depth matches the thickness of the turf bricks. Trim the edges of the repaired area neatly using a string line. Manually level the area using a scraper, matching the thickness of the turf bricks. Some of the collected fine sand can be left in the area for adjusting the flatness of the turf bed during turf brick transplantation. The remaining fine sand and grass stems are sorted and piled at the edge of the site for replanting after the turf bricks in the prepared area are removed. The turf bricks are 5cm thick and 50cm x 50cm in length and width.

[0043] Step S3, Replanting Lawn Pads: Remove the lawn paver molds from the prepared grass area, cut the connecting parts between the lawn pavers to separate them completely, and use a cart to transfer the lawn pavers to the replanting area. Replant the lawn pavers into the replanting area, ensuring the lawn pavers are joined end to end to cover the entire area. During the replanting process, adjust the height of the lawn pavers to match the height of the replanting area. The specific method for adjusting the height of the lawn pavers is to use a straightedge or a string line as a reference, and adjust the height of the lawn pavers in the replanting area by adding or removing sand at the bottom of the area.

[0044] The lawn brick has a grass stem density of 2-3 blades / cm², a grass height of no more than 2.5 cm, a surface hardness of 70-90, and a water penetration rate of more than 0.6 mm / min.

[0045] Step S4, Cover with sand and water thoroughly: After the lawn bricks are replanted, cover the surface of the lawn bricks in the repaired area with a thin layer of sand, use a scraper to smooth it, and then water it. During the watering process, wash the sand on the grass surface of the lawn bricks to the bottom. After the lawn bricks are thoroughly watered, use a lawnmower with rollers to roll them to make them more compact.

[0046] After the designated area is replanted, a thin layer of sand is covered and leveled with a rake before watering. This washes the sand from the grass to the bottom. After watering, a lawnmower with rollers is used to compact the grass, making it more compact. Thorough watering at the beginning of replanting promotes survival and makes compaction easier. Rolling also makes the newly replanted grass more closely connected to the ground, which is beneficial for the recovery of the grass after replanting. After the construction is completed, the sports field after replanting and repair has the characteristics of good flatness and dense surface, and can be used immediately.

[0047] Step S5, Maintenance: Newly replanted lawn cannot obtain moisture from the ground, so watering of the area should be strengthened to ensure the water supply for the lawn pavers during the rooting period; use a lawnmower with rollers regularly to roll the lawn to accelerate the rooting of the lawn pavers in the replanted area.

[0048] like Figure 2 As shown, the specific method for preparing lawn bricks in the grass preparation area is as follows:

[0049] Step 1: Delineate the redevelopment area in the grass preparation area: Delineate the redevelopment area in the grass preparation area and mark it. Lay a layer of tarpaulin around the site in a place that will not affect the transportation of materials, and use it to place materials to be recycled during the redevelopment process.

[0050] Step 2: Remove the turf: Use a turf cutter to remove the turf from the prepared area. The thickness of the removed turf should be 2cm. Place the removed turf on the pre-laid tarpaulin.

[0051] Step 3, Leveling the slab bed: The river sand at the grass removal site is sieved and recycled. The sieve is made with a 4mm mesh. The fine sand is placed in the designated location, while the coarse sand is backfilled into the slab bed and manually leveled. Then, the slab bed is leveled and compacted using rollers or a rammer to ensure that the construction machinery such as loaders, forklifts, and sand covering machines can move freely.

[0052] Step 4: Laying the film: Lay the film on the prepared lawn bed to prevent the lawn roots from growing downwards and to allow the roots to clump together above the film.

[0053] Step 5: Laying the lawn paver mold: The lawn paver mold is a square grid, with each square measuring 100cm x 100cm x 5cm and 1cm thick. Each square is divided into four smaller squares of 50cm x 50cm by partitions. Both the square grid and the partitions are made of plastic. The square grid is laid on the film laid in Step 4. Nylon mesh is then laid within the square grid; the nylon mesh provides reinforcement and support, preventing the lawn pavers from crumbling after removal. After the lawn pavers are laid on the field, the grass roots can grow through the nylon mesh. The mesh size of the nylon mesh is greater than 1mm and less than 2mm. A 2cm thick layer of fine sand is then laid on top; to provide nutrients to the grass stems, an appropriate amount of fertilizer and soil is mixed into the sand.

[0054] Step 6: Lay a nylon net: Lay another layer of nylon net on the fine sand to enhance the tensile strength of the root layer, strengthen the stability of the turf bed, and protect the main roots and stolons of the lawn; the mesh size of the nylon net is greater than 1mm and less than 2mm.

[0055] Step 7, Planting grass stems: Spread a layer of fine sand, 2cm thick, on the newly laid nylon netting. To provide nutrients for the grass stems, mix an appropriate amount of fertilizer and soil into the sand. After watering and settling, manually scrape and compact the sand. Plant the grass stems on the fine sand. After planting, spread a 1cm thick layer of fine sand evenly and compact it to keep the grass stems warm and moist, thus improving their survival rate.

[0056] Step 8: Cover with non-woven fabric: Cover with non-woven fabric and secure it with bamboo skewers at the edges and seams. The purpose of covering with non-woven fabric is to keep warm and moist, and to ensure the survival rate of the grass stems.

[0057] Step 9: After regular maintenance until the lawn is established, when lawn pavers are needed, remove the lawn paver molds from the prepared area between adjacent pavers. Cut off the connecting parts between the pavers to completely separate them, thus obtaining individual lawn pavers. The lawn pavers should have a grass stem density of 2-3 blades / cm², a grass height of no more than 2.5 cm, a surface hardness of 70-90, and a water penetration rate greater than 0.6 mm / min. Lawn pavers prepared using this method have strong tensile strength in the root layer, good integrity, and are not easily loosened.

[0058] Furthermore, those skilled in the art can combine and integrate the different embodiments or examples described herein, as well as the features of those embodiments or examples, without contradiction. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
