1, the pool length is generally 50m, and the allowable error is 0.03m.. An electric shock board timer (the electric shock analysis specification is 2.4m * 0.9 * 0.0 1m) can be installed at the end of the pool, and placed 30cm above the water surface of the pool walls at both ends. Immerse in water for 60 cm. The surface of the plate is brightly colored and marked with the same markings as the pool wall. ) The total length of the pond is 50m, the length of the short pond is 25m, and the allowable error is 0.02m ..
2. The swimming pool is 2 1 m wide, and the Olympic World Championships require 25m.
3. The water depth should be greater than or equal to1.8m. The walls at both ends are 30cm above the water surface and 80cm below the water surface. A rest platform can be set within a distance of 1.2 cm from the water surface on the pond wall, and the width of the table top is 10- 15 cm.
Each lane of the race is 2.5 meters wide, and the next lane is 0.5 meters. There is a lane separation line between the two lanes, which is hung on both ends of the pool wall with buoy lines. There are hooks on the pool wall, and the center line of the pool bottom and the pool bottom wall should be set as dark markings.
5. The starting platform should be centered on each centerline, with a mesa of 50 cm *50 cm. The front edge of the platform surface should be 50-70cm above the water surface. The inclination of the table top should not exceed 10 degrees, and athletes should be able to grasp the table top at the front and both sides when starting. The starting platform should be equipped with a handshaker for backstroke, which is 30-60 cm away from the water surface. There are two types: horizontal and vertical. There should be numbers indicating the number of lanes around the departure platform, arranged from right to left according to the departure direction.
6. The swimming pool should be equipped with overflow tanks on both sides to keep the requirements of the pool water and try to discharge the floating dirt on the surface. Swimming pool ladders should be embedded in the pool, the number is generally 4-6, and their positions should not affect the referee's work.
