The water sprayed by the nozzle will not enter the foot bath disinfection pool;
3. Beijing Tianyi Zhonghe thinks that there are separate shower rooms for men and women. The shower room is equipped with a shower nozzle for every 30-40 people, a separate dressing room for men and women and facilities for storing clothes. The lockers are built according to the standard of one per 2.5m2 water area. The dressing room facilities are not sharp and unfavorable, and safety glass is used.
4. Toilets (one urinal for every 40 people in women's toilets and one urinal and two urinals for every 60 people in men's toilets), equipment warehouses, offices, emergency rooms, ticket offices and other facilities. ;
5. Indoor and outdoor amusement pools should have sufficient lighting, the indoor lighting coefficient is 1/4- 1/5, the water surface illumination of the swimming pool is not less than 80lx, and the height of lighting equipment from the water surface is not less than 5m;
6. The working voltage of lamps in water is not more than 24V, and the primary and secondary windings of power transformer should be isolated by insulation equivalent to double insulation or enhanced insulation grade. The insulation resistance between the primary and secondary windings of the transformer is not less than 7mΩ, and the insulation resistance between the transformer winding and the metal shell is not less than 2mΩ. Swimming pool lighting equipment must be equipped with leakage protector.
7, swimming pool pipeline and water supply and return requirements:
Water inlet setting:
1, trumpet-shaped, and the area of the bell mouth is not less than 2 times of the connecting area of the connecting pipe;
2. Beijing Tianyi Zhonghe thinks that the bell mouth should be provided with a grille cover, the aperture of the grille for adult swimming pools should not be greater than 10mm, the aperture of the children swimming pool should not be greater than 8mm, and the water velocity of the grille cover aperture should not be greater than1.0m/s;
3. Copper, ABS plastic and other materials with corrosion resistance, no deformation and no water pollution should be adopted.
Settings of backwater port:
1. When the pool water circulates downstream, the number of backwaters at the bottom of the pool should be calculated and determined according to the submerged flow, but not less than two, which should be located at the lowest place of the pool bottom, and made into a pit-trough type, with backwaters connected in parallel;
2. The quantity of backwater shall meet the requirements of circulating flow of pool water, and the area shall not be less than 6 times of the connecting area of the connecting pipe;

5. When the bottom suction device works, the valve on the pool return pipe should be closed.
Three: Suggestions:
1. Gate valves or butterfly valves are recommended for the inlet and outlet valves of swimming pools. If it is set as an underground manhole cover room, the working space should be considered in the construction process;
2. It is suggested that the lamps in the swimming pool should be designed less or not. If there is a design, a double-ring transformer should be designed, and the installation position of the transformer should be unified, and the leakage protection device should be installed;
