The location of the water supply port of the swimming pool shall meet the following requirements:
1. The quantity should meet the requirements of circulation flow;
2. The location should try to satisfy the uniform water flow in the swimming pool without eddy currents and stagnant water;
3. When distributing water at the bottom of the pool, it should be evenly arranged in the middle of the marking lines of the two swimming lanes;
4. When distributing water to the pool wall, the distance should be 2-3m, and the distance between the corner and the other pool wall should not exceed 1.5m; the depth should be 0.5-1.0m below the water surface of the swimming pool;
5. When the diving swimming pool uses the pool wall for water distribution, the water supply port on the second floor should be set, and the water supply ports on the upper and lower floors should be staggered. The height of the water supply port from the bottom of the pool should not be less than 0.5m.
The structure of the water supply port shall meet the following requirements:
1. The bell mouth type should be adopted, and it should not be less than twice the cross section of the connecting pipe;
2. A grid shall be provided, and the grid shall be made of corrosion-resistant and non-deformable materials;
3. The water flow velocity in the grille gap should not be greater than 1.0m/s;
