How to Measure Take-off
The hockey court is a rectangular field with a longitudinal axis of 91.4m and a horizontal axis of 55m. The construction payout is based on the center of the field. The center point of a goal line is taken as the base point, and the center point of the goal is measured at 91.4m. The distance from the vertical center line of the center point to both sides is 27.5m, which is the end line of the field. The end point, connected to the opposite end point, is the sideline of the site. The two edges should be parallel to the centerline. After measuring the payoff, you can use diagonal methods to measure the distance between two diagonal lines.
Due to the needs of the competition facilities and the need of sports activities, the line is parallel to the edge 1m away from the sideline of the venue, and is equal to the two lines of the sideline, called the limit line, at the same time 2m behind the end of the two goal lines, parallel to the end line Measure two lines to form a rectangle of 95.4mx57m. The site structure within this rectangle should be consistent. See below.
The height of the centerline of the site should be equal to the height, and it should also be the height of control. Generally, hockey is mostly drained horizontally, and the slope is mostly 0.2%~0.5%.
A drainage ditch is designed on the outside of the site, and the centerline of the drainage ditch should also be parallel to the centerline of the site.
Two temporary standards should be set at both ends of the site to facilitate construction. Temporary leveling points should be set on fixed permanent buildings. Closed differentials should be detected for both leveling points.
