Choosing a metal collapsible pool

Today, due to the fact that private suburban construction is taking on a very large scale, the demand for such structures as home gardens for swimming, and in particular collapsible, has increased significantly. With sufficient careful consideration, you can see that this type of structures is a leader in such a relevant category as “price-quality” – portable pools can be installed in completely different places, and they are especially relevant when the pool needs to be placed where To mount a stationary is not possible, for example on the roof of a house. Another advantage of the collapsible basin is its relatively low cost, which makes them affordable for the most massive buyer.
There are three main types of collapsible pools according to the material of manufacture – they are plastic, inflatable and metal. However, plastic pools have some drawbacks that do not allow them to be used widely enough – this is the relative fragility of the material and its unreliability, which leads to short service lives. The same applies to inflatable structures. The most relevant in this regard are precisely collapsible basins made of metal – it is the metal that provides facilities of this kind with all their positive qualities, which are essential for sufficiently effective and long-term operation of portable type pools.
All metal collapsible pools differ in characteristics, but there is a single standard that all manufacturers try to adhere to. The most famous manufacturers of collapsible basins supply them from Germany and the USA, but in recent years their production has been established in our country, and the quality of such facilities is often not inferior to the quality of foreign products. For the manufacture of the walls of the pool, mainly steel tape is used with a thickness of 0.6 to 0.8 mm (for pools of 1.2 and 1.5 m deep, respectively). The outside wall is covered with protective enamel, and from the inside – with PVC film 0.6 mm thick. The upper and lower edges have plastic handrails. The shape of the pools can be very different – it is a circle, an oval, and even a “eight”, while the sizes of the round ones vary from 3 to 10 meters in diameter, and the “eight” and oval ones 490×300-1100×550 mm. The installation of the pool requires a well-compacted sand or reinforced concrete “cushion”; if the pool is much larger than the average, then only a reinforced concrete base with two supporting walls on the long sides of the pool is needed. As an alternative, supporting structures are concreted into the reinforced concrete base, which should be included in the mandatory pool kit.
If the pool is round, then it can be put on a sandy platform, and if it is of any other shape, it can be bury. Deepening is performed either partially or completely, but it must be borne in mind that the device of the deep pool is much more difficult. To install a submerged pool, it is necessary to dig a pit with walls sloping outwards. The bevel should be 45 degrees, and the shape of the pit and its dimensions are indicated in the drawings, which are attached to the company purchased the pool. The bottom of the pool is filled with concrete and should be absolutely flat and horizontal. After the concrete has dried, a frame is mounted on top of the cover and a film is laid. Between the walls of the pit and the frame is filled layer, which is a dry cement-sand mixture. Sand is poured from above. It is necessary to take into account the condition of the soil, its composition and groundwater level – groundwater should not reach the bottom concrete slab of the basin, but if this level is still high, then drainage is necessary to completely drain the area of ​​the basin.
The functioning of a collapsible basin, like any other solid construction, implies proper technical support. The kit, which the manufacturer must supply with the design itself, should include a filter and a pump, a device for water replacement (the so-called “skimmer”), a ladder, and a test kit of chemicals. Also included is a set of all the necessary pipes and connections. When working, quartz sand of a specially defined fraction is poured into the filter, and this amount should be sufficient for at least three years of uninterrupted use of the pool. The volume of the filter should be selected in accordance with the cubic capacity of the pool. “Water vacuum cleaner”, which is offered for more complete care of the pool, connects to this filter and collects all the accumulated garbage and mud from the bottom of the pool. It is necessary to clean the pool regularly, at least once a week, otherwise the water will “bloom”. This phenomenon can be dealt with with the help of chemicals destroying wet algae, contributing to the “bloom” of water. After treatment, the algae sediment is removed from the bottom with a “water vacuum cleaner”.
