I. Common structures of volleyball courts The structure of volleyball courts, the requirements of the FIVB, the ground of the world competition venues can only be wood or synthetic materials. China's volleyball courts, schools, clubs, and driving ranges are mostly open-air venues. Common volleyball courts, the ground structure has soil surface layer, plastic surface layer and asphalt concrete, cement concrete surface layer and so on. At present, the cement concrete surface and the asphalt concrete surface layer are hardly built because they are hard and have no guarantee for the athlete's body. The surface structure is shown in the figure below. 1—sintered soil; 2—limestone 12%; 2—Soil Compaction; 4—Plastic Surface; 5—asphalt concrete; 6—Lime, fly ash, gravel 7—Figure 2(1)— Fine sand layer Two. Volleyball court ground floor construction method The construction technology of the ground floor of the volleyball court is basically the same as other sports venues. There are some important technical operations for the construction of the plastic surface of the volleyball court. Note that: 1. For plastic materials, low wax-containing raw materials should be selected to prevent waxing on the surface after pavement. 2. When all kinds of materials are mixed on the spot, the method of measurement shall be adopted, and the scale shall be accurately and evenly mixed (uniform chemical change). 3. During the construction operation time, it is necessary to prevent the paving operation of the unfavorable operation such as morning fog weather, rain weather, and wind days, and to prevent the paving operation when the base layer is wet. 4. In case of grassroots unevenness, the method of scraping chemical putty can be used to level it properly. 5. During the construction of the plastic surface layer, a plastic test piece of 0.5mx0.5m shall be produced at the same time and sent to the inspection unit for inspection. The result is the main part of the completion data. 6. Soil material surface construction, the most important thing is that the material mix ratio should be accurate. When rolling, it should be rolled under the optimal moisture content. After lightly rolling and leveling, and then using heavy-duty grinding, the surface layer can not have the phenomenon of tumbling. .
