Concrete (or reinforced concrete) rings are currently a very popular building element that allows you to quickly and efficiently solve a number of issues, in particular when arranging sewers, as well as strengthening the walls of wells.
There are only two main areas of application for concrete rings:
1) arrangement of manholes on utility sewer lines. Rings are much more reliable than brickwork, their installation takes a minimum of time, various sizes allow you to equip inspection wells, depending on the technical conditions;
2) arrangement of septic tanks. A unique opportunity to quickly, inexpensively and efficiently equip a local cesspool where there is no centralized sewage system, for example, in rural areas.
To equip a good septic tank made of concrete rings, it is necessary, first of all, to determine the size of the cesspool, which primarily depends on the intensity of use of the future sewage system (the number of people living in one house, the presence of a toilet, a kitchen sink with running water, a shower or a bath , washing machine, etc.d.). The desired dimensions of the septic tank will help calculate the size and number of concrete rings, which come in different diameters – from 70 cm to 2 m. Most often, rings with a meter diameter are used, since too large ones can create some specific problems during the use of the finished structure.
It is not difficult to assemble the entire structure of the septic tank, in addition, you can do it even easier – purchase a ready-made kit for septic tank equipment with calculated characteristics, a full set of rings, a bottom and a special cover equipped with an inspection hole. Many serious companies producing reinforced concrete products have several options for such modular structures.
You can mount a septic tank of concrete rings yourself, together with a partner, using a small lifting autocrane and in the presence of some working skills.
