Description

Technical Field

[0001] The invention relates to the technical field of clay tennis court construction, and in particular to a maintenance-free clay tennis court construction method. Background Art

[0002] Tennis has been introduced to my country for more than 100 years. Tennis courts can be divided into three types: hard courts (acrylic courts such as the US Open and Australian Open), grass courts (such as Wimbledon), and clay courts including sandy courts (such as the French Open). Clay tennis courts are deeply loved by tennis enthusiasts because of their comfort and less harm to human joints, and have become one of the four major international tennis open events.

[0003] Traditional clay tennis courts are expensive, difficult to construct, and complex to maintain, which has caused people to stay away from them during their promotion and use, and has been greatly restricted in their promotion and development. Therefore, how to build a clay court on the upper floor or on the basis of the original hard court (including: cement floor, asphalt floor, original hard court) to broaden the development space of clay tennis courts, and how to make the court have good use effect and simple maintenance is an urgent problem to be solved. Summary of the invention

[0004] The purpose of the present invention is to provide a maintenance-free clay tennis court construction method, which can build a clay tennis court on an upper floor or on the basis of an original hard court, breaking through the inherent concept that a clay tennis court cannot be built on an upper floor. The court is beautiful, comfortable, durable, and easy to maintain, thus expanding the development space of the clay tennis court.

[0005] In order to achieve the above object, the present invention provides the following technical solutions: A method for constructing a maintenance-free clay tennis court comprises the following steps: S1. Foundation treatment: On the original hard ground foundation, use cement self-leveling or silicon PU material to make the foundation flat; S2. Artificial grass construction: Customize artificial grass equal to the area of ​​the site, build granite stone edge protection around the site, bond the artificial grass as a whole into a whole piece, and then firmly bond the four sides of the artificial grass and the granite stone; S3. Construction of red soil base: The base material is composed of 40% crushed gravel, 30% red soil, 20% clean water sand and 10% lime. After repeatedly mixing the above materials, fill them into the artificial grass, and the molding thickness is controlled at 2cm; S4. Construction of red soil surface layer: The surface layer material is composed of 40% pure red soil, 20% red soil powder, 30% machine-made red sand and 10% limestone powder. After the above materials are fully mixed, they are filled on the red soil bottom layer material; after the artificial grass is fully covered, it is leveled and compacted. The molding thickness of the red soil surface layer material is controlled at 2cm, and the molding height of the venue exceeds the artificial grass by 1-2cm; S5. Construction of sliding layer: The sliding layer is composed of 65% clay brick powder and 35% red sand. The prepared sliding layer material is evenly spread on the red clay surface material. The thickness of the sliding layer is controlled at 2mm. Use a special support for red clay venues to support it evenly. S6. Production of long-term lines: accurately locate the position of the site lines according to the site specifications; make edge guards according to the width of the site lines. The edge guards should be straight and stable, and a wire groove should be formed inside the edge guards; nail iron nails are nailed every 10 cm in the wire grooves, and the nails should be close to the edge guards to form two rows. The nails are connected with No. 18 iron wire to form a woven mesh to enhance the strength and stability of the long-term lines; pour the processed PU material in the wire grooves, and pay attention to maintaining the flatness when pouring the material; after the PU material solidifies and takes shape after 24 hours, perform maintenance, sorting, and cleaning to keep the straightness and beauty of the long-term lines; use the line drawing paint that matches the PU material to draw the lines.

[0006] Preferably, in step S2, the artificial grass has a height of 3 cm and a density of not less than 48,000 needles per square meter.

[0007] Preferably, the particle size of the crushed gravel in step S3 is 4 mm.

[0008] Preferably, in step S5, the machine-made clay brick powder and red sand are 20-80 mesh, wherein 40-80 mesh is used for indoor venues and 20-40 mesh is used for outdoor venues.

[0009] Preferably, in step S6, the edge protection includes a bottom line and other lines, the bottom line is 10 cm wide, and the other lines are 5 cm wide.

[0010] In summary, the beneficial effects of the present invention are as follows: the red clay sports field constructed by the present invention has good use effect and simple maintenance, overcomes the disadvantages of high cost and great construction difficulty of red clay tennis courts, solves the problem of building a red clay court on a hard ground, and this construction method is applicable to the construction of indoor and outdoor tennis courts, expanding the development space of red clay tennis courts; the venue is beautiful and comfortable, durable, and not afraid of rain. The venue can be used half an hour after the rain stops, which is suitable for the rainy conditions in the south. The venue does not peel or crack, and the flatness meets the requirements.

[0014] Specific steps: 1. Basic processing On the original hard ground foundation (including cement ground, asphalt ground, various hard grounds), use cement self-leveling or silicon PU material to make the foundation flat; 2. Artificial grass construction Customize artificial grass equal to the area of ​​the venue, with a height of 3cm and a density of no less than 48,000 needles / square meter; build granite stone edges around the venue, bond the artificial grass as a whole into a whole piece, and then firmly bond the four sides of the artificial grass to the granite stone; 3. Construction of laterite base materials The bottom layer material consists of: 40% crushed gravel (about 4mm in diameter); 30% red soil; 20% clean water sand; 10% lime; the above materials need to be repeatedly mixed and evenly filled into the artificial grass, and the molding thickness should be controlled at 2cm; 4. Construction of red soil surface materials The surface material composition: pure red soil 40%; red soil powder 20%; machine-made red sand 30%; limestone powder 10%; the above materials need to be fully mixed and evenly filled on the red soil bottom material. After the artificial grass is fully covered, it is leveled and compacted. The thickness of the red soil surface material is about 2cm, and the height of the venue exceeds the artificial grass by 1cm-2cm; 5. Sliding layer construction The sliding layer is composed of 20-80 mesh machine-made clay brick powder and red sand, of which clay brick powder is 65%; red sand is 35%. The prepared sliding layer material is evenly spread on the red clay surface material (40-80 mesh is used for indoor venues, and 20-40 mesh is used for outdoor venues). The thickness of the sliding layer is controlled at about 2mm. Use a special support for red clay venues to support it evenly.

[0015] 2. Long-term production of the site The long-term line is one of the important links in the production of the venue. The long-term line construction will be carried out after the artificial grass is laid.
