How is the sand volleyball court built?
The beach volleyball court is also a rectangle with sidelines on one side of the long side and end lines on the side of the short side. The intersection of the two lines is a right angle. The beach volleyball court and the outdoor volleyball court are basically the same, and there are different places.
The barrier-free area requirement of the beach volleyball court is different from that of the outdoor volleyball court. The distance between the two sidelines is at least 5m, and the barrier-free area outside the terminal line is at least 4m. Construction line must be laid according to the size of the beach volleyball court, construction trenches should also be excavated in accordance with this value. See below.
1—Centerline; 2—Sideline;
2— Site end line; 4—Accessibility area
The structure of the beach volleyball court is a fine sand layer with a thickness of 0.3m. The scope of construction includes accessibility areas. The technical requirements for sand are shown in the table below.
Technical requirements for sand
project | skills requirement | ||||
Particles Grading | Square hole size (mm) | 0.16 | 0.315 | 0.63 | 1.25 |
Accumulated sieve residue (%) | 100~90 | 85~55 | 40~16 | 25~10 | |
Soil debris content (%) | ≤3 | ||||
Sulfide and sulfur salt content (converted to SO3) (%) | ≤1 | ||||
Organic matter content (colorimetric method) | Color should not be darker than standard solution color | ||||
Other sundries | No stones, shells, cinders, grass roots, etc. | ||||
When constructing the beach volleyball court, the emphasis is on the sand quality and structural thickness. After construction, water can be sprayed to set aside a part of the surface, and then a part of the sand can be filled. Leveling can be done without rolling, and a flat-plate electric vibrator can be used to smooth out the surface.
