TECHNICAL FIELD

[0001] The present application relates to the technical field of artificial turf, in particular to a construction method of artificial turf. BACKGROUND

[0002] Football has been more and more popular among Chinese people, and the number of people engaged in football has doubled every year. Football field is indispensable to football, and football field is mainly divided into natural grass football field and artificial turf football field. Natural grass football field cannot meet the high frequency of use due to high maintenance cost, so people focus on the construction of artificial turf football field. In order to improve the resilience of the lawn, the existing artificial turf football field directly fills the particles into the artificial turf. This structure has the following defects: first, the filled particles pollute the surrounding environment; second, the cost of artificial turf is high; third, when it rains, rainwater can only be discharged on the surface of the lawn, and the filled particles are easy to be washed away by water, resulting in particle loss and uneven ground, which is easy to cause injury to players.

[0003] For example, the patent document with publication number CN108914746A discloses a construction method of a new artificial turf playground, which is characterized in that the construction method comprises the following steps: (1) leveling the site, removing plants and sundries on the original land; (2) taking the midpoint of the site centerline as a reference point, setting a slope towards all directions based on the reference point, forming a tortoise-back type drainage structure with high middle and low periphery; (3) compacting the soil layer, repeatedly compacting and densifying the soil layer with a 10-15 ton vibrating roller to prevent uneven settlement of the soil layer; (4) laying waterproof coiled material, laying a layer of waterproof coiled material on the surface of the compacted soil; (5) laying a multifunctional base pad, the multifunctional base pad is laid on the surface of the waterproof coiled material; (6) laying artificial turf, the artificial turf is laid on the surface of the multifunctional base pad; (7) filling quartz sand, filling quartz sand on the surface of the artificial turf by professional machinery or manually; (8) filling buffer particles, filling natural cork particles or synthetic rubber particles on the surface of the quartz sand. The construction method of "filling synthetic rubber particles" in the technical solution has the above-mentioned defects. SUMMARY

[0036] Step S1, compacting and leveling the site: removing the sundries on the surface of the site, turning over the site with a plow, then breaking and raking the site soil with a rotary cultivator, and then repeatedly rolling and compacting the foundation with a 30-40 ton roller, and leveling the site to form a soil compacting layer 1.

[0037] Step S2, paving gravel: paving gravel with a particle size of 10-30 mm on the surface of the soil compacting layer to form a gravel layer; the specific paving method is: roughening and pushing the gravel with a particle size of 10-30 mm on the surface of the soil compacting layer with a bulldozer, then manually fine leveling, and then compacting with a 12-ton vibrating roller to form a gravel layer 2 with a thickness of 8-20 cm; during the paving of the gravel, a drainage pipe is pre-buried, and the drainage pipe is a Yashan net type permeable pipe. The drainage pipe 7 is laid in the gravel layer 2 to drain the water seeping into the gravel layer 2 from the surface of the turf, and in order to improve the drainage performance, the drainage pipe 7 is a Yashan net type permeable pipe, and a plurality of water permeable holes are distributed on the pipe wall of the permeable pipe.

[0038] Step S3, laying a sand particle blocking and filtering layer 3: laying a non-woven fabric on the surface of the gravel layer to form a sand particle blocking and filtering layer 3 that is permeable to water but not to sand. The non-woven fabric effectively blocks the medium and fine sand in the fine sand buffer layer, preventing the medium and fine sand from seeping downward into the gravel layer 2, thereby improving the drainage effect of the gravel layer 2.

[0039] Step S4, laying the medium-fine sand buffer layer 4: on the surface of the sand particle barrier filter layer, medium-fine sand with a particle size of 0.1-1mm is laid, and the thickness of the medium-fine sand buffer layer is 8-20cm.

At the same time, the sand covering width is adjusted, and the medium-fine sand is filled for multiple times. After the second pass, the grass filaments of the lawn layer are brushed to form the medium-fine sand surface layer 6.

[0042] The specific method for filling the medium-fine sand is as follows:

[0043] S6.1, the medium-fine sand is filled into the hand-pushed sand covering machine and shaken, and straight lines are drawn in the east-west direction on the lawn layer. When the sand covering machine is running, the straight lines are used as the center lines, and the medium-fine sand is filled in one pass with a thickness of 3-5mm;

[0044] S6.2, in the second pass, the straight lines are drawn in the north-south direction, and the medium-fine sand is filled in one pass with a thickness of 3-5mm. Then, a triangular plastic grass combing plate is used to repeatedly comb the grass filaments until the grass filaments of the lawn layer are completely upright.

[0045] S6.3, in the third pass, the straight lines are drawn in the east-west direction, and the medium-fine sand is filled in one pass with a thickness of 3-5mm. The total thickness of the sand covering is ensured to be 9-15mm, and the grass filaments of the lawn layer are brushed again.

[0046] S6.4, steps S6.2 and S6.3 are repeated, and the filling of the medium-fine sand is completed in the seventh pass.

[0047] In addition, in step S1, before the site is compacted by the road roller, a water supply pipe 8 is embedded in the soil compaction layer 1. The gravel layer 2 is provided with a plurality of spray pipes 9, the lower end of the spray pipe 9 is connected to the water supply pipe 8 through a branch pipe 10, the upper end of the spray pipe 9 is sequentially penetrated through the sand particle barrier filter layer 3, the medium-fine sand buffer layer 4, the lawn layer 5, and the medium-fine sand surface layer 6, and is connected to a self-rotating spray head 11. The spray pipe 9 adopts a telescopic structure, and is retracted below the lawn when not in use.
