In determining the reinforced concrete section of swimming pools, besides the construction and static requirements, the coating material is also important in terms of hygiene. During the pool project phase, while preparing the details, if the studies are carried out by taking these issues into consideration, the problems to be encountered in the next stages will be minimized.
The slope to be given in the cross section is very important for the swimming pool water to overflow and clean properly. The 5% slope between the pool edge and the overflow channel ensures smooth overflow of the pool water. Thus, it is also ensured that the dirt accumulated on the surface is collected. Another 2% slope is made in the opposite direction on the other side of the pool overflow channel. The purpose of this slope is to prevent the contaminated water in the walking area around the pool from mixing with the pool water. Another issue that should be reminded here is that the handle and anti-skid fixing should be done by experts and with the help of a level so that the water can overflow equally from all sides of the pool. Otherwise, as the water will not overflow equally, both the aesthetics of the pool will not be provided and the water will not be sufficiently cleaned in some areas.
While the excavation is done and the blockage is laid, the pool drainage line that will ensure the removal of the water coming from outside should not be forgotten.
While the floor and curtains of the pool are poured, all hydraulic connections, discharge manholes, PVC pipes, strainers, underwater lighting fixture buckets and all necessary concrete transition parts should be placed in place.
While avoiding structural joints in the pool, it is often necessary to leave a dilatation joint around the pool. Since the static work of the pool filled with water and the surrounding corridors and terraces, which mostly sit on the ground, is different, dilatation is required. One of the important issues to be considered is that these structural joints should never be covered with material. These joints should be sealed with materials such as elastic silicone.
In terms of water insulation, cold joints should not be left at the stage of pouring concrete in swimming pools. In case it is left, care should be taken to take measures such as water retaining tape at cold joints.
After the concrete casting stage, if a smoothing process with plaster and alum is needed on the surface, the plaster should be prepared with additives, if possible, and its thickness should not exceed 8-15 mm. Larger correction may cause ruptures from the concrete surface.
In the reinforced concrete stage, the accuracy of the pool dimensions is very important. Especially in competition pools (Olympic swimming pool, competition and water polo pools, etc.), the control and approval to be made by the swimming federation may be required.
In swimming pools and ornamental pools, after waterproofing, the pool is filled and waited in order to check the impermeability and prevent water loss before coating. The pool should be kept full of water for about 15 days. This period should not be less than a week.
In order to facilitate the cleaning process of the pools and to provide hygiene, it is recommended to use special joining parts, which are inner and convex, instead of joining the pool floor and wall. Porcelain products with special cross sections lined at the edge of swimming pools are classified as handles. This material shows excellent chemical, physical and mechanical properties with a special production and cooking. First of all, the handles and non-slip elements should be placed on the relevant parts of the pool one by one in the desired form and adjusted until the desired slopes are obtained. This slope should be even across the pool. These checks should be done in the company of experts. The products should be glued by keeping the 5 mm joint between the non-slip and handles, paying attention to the smoothness of the parts of the handles coming into the pool.
It should not be forgotten that a successful application process does not only depend on the quality of the material. How and by whom the process is performed is as important as the quality of the material. After the adhesive is completely dry, the joint gaps between the materials are completely emptied and filled with a flexible, latex or epoxy based semi-elastic joint filling material. Normal joint filling material should never be used in order to prevent it from being affected by water, air and other environmental factors. After the application, the cleaning process should be done quickly and carefully. If the pool cleaning process is not carried out with care or if it is done late, it is not possible to clean the residues on the materials. [video]
After the pool coating is finished, it is recommended to use a plastic cover to avoid splashes from construction work and to protect the floor area. After the pool material laying process is finished, operations such as iron cutting should not be done around it. Even if it is not known at that time, after a certain period of time, the damages of iron burrs are observed on the materials. The pool should be filled after the construction, mechanical and electrical installations are completed and the fertilized soil laying and grass addition processes are completed in the garden.
About Pool Maintenance
The water in a well-maintained swimming pool with a filtration and disinfection system in accordance with standards is cleaner than sea water. However, adequate maintenance cannot be provided in many pools. Swimmers in public pools must obey hygienic precautions. You should not enter the swimming pool with sun oil. Before entering the pool, it should be washed thoroughly by taking a shower, and it should be ensured that the feet are rinsed with disinfectant water. If possible, it should be ensured that pool users enter the pool by passing through the photocell compulsory shower.
Periodic maintenance of swimming pools should be done on time and pool water should definitely be brought to a healthy environment. Large multi-user swimming pools should be closed to swimmers once a week, and weekly maintenance should be done. The names of the company or persons undertaking the maintenance of the pool, the type and brands of the chemicals used and similar issues should be included on the special information board to be informed to those who use the swimming pools. Pool water should not be drained in winter. In winter, the water of the pools should be left full and winter maintenance chemicals should be used. The pH value of the water to be filled in the pool should be considered as well as the cleanliness.
After starting the circulation of the pool water and making shock dosing for disinfection, only the next day the chemical rate in the water should be checked with a digital or manual test kit and if the values are normal, the pool should be entered.
It should not be forgotten that swimming in a healthy, hygienic and clean pool is only possible with proper and regular care.
Pool Winter Maintenance
It is recommended to keep open pools full in winter, especially in regions where winter conditions are harsh. Thus, the pool surface and structure is better protected against external factors. The water in the pool provides resistance to the effects and protects the reinforced concrete with the pressure it exerts on the pool surfaces.
The filled pool will be more sensitive to external effects, as well as preventing the pool coating from being damaged by foreign substances falling into the pool. For example, foreign materials such as dead leaves and dust can stain the surface of the pool coating.
In addition, maintenance of the pool throughout the winter requires less material and moral maintenance in preparing the pool for the season.
The "frost" that will occur in the outdoor swimming pools in winter and when the temperature drops below "0" ° C may cause damage to the coating materials. It is imperative to take some measures to counteract the negative effects of frost:
1- Approximately 30 cm below the pool water surface.
2- Flexible ice pressure pads and anti-frost winter protection tubes are hung on the pool water surface in order to prevent the ice layer that may form on the pool surface.
3-In pools left full, measures should be taken to facilitate spring cleaning. Algae formation and lime subsidence should be prevented. Winter protector and winter care chemicals protect the pool water throughout the winter. It facilitates spring cleaning. It prevents the formation of algae, dirt and lime settlements.
4- Pool water; The pool is sucked from the bottom suction and circulated, then heated to 10-15 ° C and given to the pool. Circulation is done at approximately one quarter of normal operating conditions.
5- In addition to these measures, the top of the pool can be covered with tarpaulin or a heat-protective cover material.
