Common Issues in Water Park Construction

When it comes to water park equipment, the technology behind indoor swimming pool equipment is straightforward and well-established. However, this often leads to it being overlooked during the design phase. Even though many indoor swimming pools in the country utilise advanced imported equipment, neglecting the finer details can result in less than ideal performance. Construction units frequently encounter water park construction issues that need addressing.
Indoor Ventilation Concerns
Indoor swimming pools generally require heating, except during the summer months. Once the pool water is heated, it generates water vapour, which can lead to condensation and an uncomfortably high indoor temperature. In summer, sunlight through the roof can make the space stifling. Without proper exhaust facilities, condensation can occur on the roof, sometimes resembling rainfall. This can cause metal grid paint to discolour and rust, wood decorations to warp and rot, and plastic coatings on aluminium ceilings to peel and develop mould.
Solutions include installing mechanical exhaust devices with low-noise fans, using separate air conditioning systems for the pool area to supply fresh air, and controlling pool water temperature to not exceed 30°C. During winter, hot air conditioning can maintain warmth, and since guests typically visit in the afternoon and evening, continuous heating isn’t necessary.
Choosing the Right Pipeline Materials
Swimming pools require numerous pipes, and selecting the right materials is crucial. Two ideal options are thin-wall copper pipes, which are reliable and resistant to scaling but costly, and UPVC pipes, which are lightweight and easy to install but not temperature resistant. Copper pipes are suitable for high-pressure circulation systems, while UPVC pipes work well for other areas. If the pool is on a higher floor, metal pipes are safer. UPVC pipes must be well-supported to prevent vibration under pressure.
Decorative Material Selection
Due to high humidity levels, careful selection of decorative materials is essential. Walls should feature light-coloured marble or glazed tiles, avoiding paint or coatings. Non-slip floor tiles are recommended, and granite should be avoided. Ceilings should use aluminium plates or plastic boards, steering clear of wood. Roof grids should allow for future anti-corrosion treatment and easy cleaning, especially for roadside buildings with large glass areas. Stainless steel is preferred for water inlets, outlets, and ladders, while plastic grilles are common for overflow gutter covers, despite being challenging to clean.
Pool Bottom Suction
The limited suction at the pool bottom can lead to noticeable dirt accumulation after three days. Cleaning methods include brushing dirt towards the suction port, though this can disturb sediment, or using siphons or pumps, which are cumbersome and waste water. The ideal solution is using the circulation system and suction head, which leverages existing systems with minimal additional equipment. This method is effective, with plastic suction cleaners, hoses, and push rods being lightweight and easy to operate. Design considerations include:
- Positioning sewage suction ports on the upper pool wall.
- Evenly distributing suction openings without excess to maintain sufficient suction power.
- Separating the sewage suction loop from the main circulation system for independent control.
- Using soft hoses for easy movement within the pool.
Water Injection and Venting
The pool’s side walls and bottom are typically decorated with blue bricks, which can accumulate dirt over time. Regular cleaning is necessary, and attention must be paid to water injection and venting timing:
- Ensure sufficient water supply, with a maximum supply time of 4 hours, and lay water supply pipes separately.
- Vent pipes should have minimal turns for quick venting.
- Pool water should drain into the sewer, with reuse considered.
Maintaining Water Quality
City tap water doesn’t meet swimming pool standards and requires further treatment. Alum treatment is ineffective due to long precipitation times and sediment. Refined aluminium sulfate is more effective. Fresh water should be added daily to prevent water from turning green and moss growth. Full-water pools are preferable, with water levels controlled by a balanced tank and surface water frequently overflowed to prevent oil accumulation. Disinfectants should be simple and effective, and the circulation system must ensure adequate flow to avoid dead zones and heating delays.
Sand Filter Considerations
Imported sand filters come in various materials like carbon steel, cast iron, and fibreglass. Key features include:
- Easy-to-operate multi-way valves that change states with a 180-degree handle rotation.
- Reliable sealing to prevent leaks.
- Pressure gauges for monitoring backwash timing.
- Inspection holes for maintenance and sand replacement.
- Valves on inlet and outlet pipes for easy maintenance.
- No need for spare sand tanks.
- Ensuring backwash pressure is maintained.
Heating Requirements
Indoor leisure pools typically have a small capacity and are in air-conditioned environments, maintaining around 25°C. Therefore, heating requirements are minimal, and a rapid heat exchanger is sufficient.
Additional Considerations
Before applying decorative materials, ensure pool inlets, outlets, and lights are installed and pressure-tested to prevent leaks. Pool lights should be at half the pool wall height and reliable, as replacement is only feasible underwater. Pipes along the pool’s outer wall are usually in the lower ceiling, so design should allow for maintenance access and space. The overflow pipe of the balanced tank shouldn’t connect to the backwash discharge pipe, and coagulants should be added to the pump’s suction pipe. Proper coordination of overflow ports and pipes is necessary to avoid noise, and the deep end of the pool should be near the machine room.
