Volleyball court construction survey and release method

The volleyball court is a rectangular playing field. The long side is called the sideline and the short side is called the sideline. According to the requirements of the FIVB, in a world-wide competition venue, there must be an obstacle-free zone outside the perimeter line, with a width of at least 5m and at least 8m outside the end line. The barrier-free space above the playing field should be at least 12.5m high. At the outside of the general practice site and outside the sidelines, there should also be a barrier-free area, but the size should be at least 3m. See below. The athlete's bench and activity area should be outside the accessible area.

The volleyball court is a flat venue. When the site is outdoors, a 0.5% cross slope can be designed to facilitate drainage.

Construction line should be based on the vertical center line of the site as the baseline, first determine the endpoint of one end of the site, longitudinally measure 18m, determine the end point of the other end line, use the theodolite to fix at the end point, look at the other end point, and then left 90. Measure the intersection point of the 4.5m fixed end line and the edge line, and measure and release the fixed point of the outer extension line of 2 points at the same time. Move the theodolite to the other end point, do the same set point measurement, and finally connect the points to get the edge line and the end line. In the extension line of the edge line, set the endpoint of the barrier-free area, and measure 9.5m left and right, and then the edge line. Accessible area 5m line connected.

In order to facilitate the construction, permanent standards can be brought to the construction site to be a temporary leveling point. The temporary leveling point should be located on a permanent building. If there is no building nearby, a block can be built on the site outside the site. In the ground 0.5m deep, 0.3m above the ground, the area of ​​the station is at least 0.5mx0.5m, a steel pile is pre-embedded on the ground, and the error of the temporary leveling point should be regularly checked within the specification requirements.
