VERTICAL BURYING TANKS
Plastic vertical burying tanks are constructed similar as appropriate plastic vertical above-ground tanks. From regular vertical above-ground tanks they differ only by additionally reinforced cylinders, i.e. made with outside trimming.
We can say that they are partially buried tanks because they are buried only to the height of cylinders – it is not allowed to pour sand or ground on conical roof or the tank.
- Tank is being buried on a hard terrain, i.e. in a hard land, that is a land that is not a soft arable land, not a soft sandy land, nor a swamp land or similar
- There is no underground water on the place of burring
- It must be secure that, in a case of strong precipitation or if it comes to sudden snow melting, torrential watercourses that are then being created, ie. water that is drained, doesn’t get in contact with total tank, especially when its empty or half-empty.
While burying, 20cm of sand must be poured on a bottom of an excavated hole and compressed. The whole itself must have a diameter at least 50cm bigger than the external diameter of a tank, and that space between wall hole and a tank must also be covered with sand, in layers of 20cm each and every layer must be compressed before the next one. It’s not allowed to pour sand or land on a conical roof of a tank.
