With the construction of more and more swimming venues, due to the lack of design, construction technology and negligence in the quality control of swimming pool bricks, the following quality problems occur more or less in the later operation after the completion of the swimming pool: for example, the bottom of the swimming pool is arched; Cracking of pool brick at the edge of the pool; The pool wall and pool brick fall off (similar quality problems are found in the construction process and later operation of swimming pools everywhere). How to prevent this quality problem, the practice of professional technicians for many years is summarized as follows:
(1) The phenomenon of Deglazing, glaze cracking and falling off of swimming pool tiles and swimming pool mosaics is mainly due to the poor control of the quality source of swimming pool tiles by the purchaser. In order to reduce the cost, non special swimming pool tiles are used. For example, the purchaser often uses mosaics pasted on the outer wall, porcelain tiles pasted on the inner wall and large-size 300 * 300 ceramic tiles. As a result, these mosaics and ceramic tile glaze are not acid-base resistant The specification is too large and the water absorption rate does not meet the underwater environment. As a result, the above situation starts in less than a year, and the repair cost increases, affecting the operation of swimming pools and venues, and the gains outweigh the losses; What is more serious is that in the past, the safety incidents of falling off and stabbing people in the swimming pool were caused by these application errors. Because individual suppliers only provide ceramic tiles and do not have the ability to provide professional paving guidance, they led to various problems and repair of mosaic or swimming pool tiles in the later stage.
(2) The swimming pool structure shall be self waterproof reinforced concrete structure, and the selection of auxiliary waterproof layer and leveling layer materials and node method shall be adopted. The designer shall select experienced and reliable design nodes. For example, the waterproof layer shall be made of crystalline permeable waterproof material (cement-based type). The pool leveling layer shall have good bonding effect. At the same time, the pool bottom leveling layer must be provided with deformation joints to meet the deformation requirements of different substrate temperatures of the pool body and reduce the probability of hollowing and falling off of the pool bricks pasted later.
(3) The quality of swimming pool bricks and the professional and experience suggestions provided by the manufacturer are very important. Similarly, the selection of binder and joint filler for auxiliary materials must adopt the formula brand special for swimming pool; During construction, try to select an experienced professional team to ensure that the construction process quality is controlled.
