The concrete wells are strong and durable. They are relatively simple to manufacture, is relatively easy and their installation.
Mount wells from concrete rings of any size and weight. If the ground allows, we can arrange a monolithic body of water. This made the one ring, it is placed in water-bearing ground, and then lowered into the formwork of the concrete weight — it turns out almost solid cylinder.
Concrete rings for the well can be without a lock (simple) and with a lock. To the first when mounting has not moved, they are fastened among themselves in four to six places with steel clamps. To this end, the rings leave holes, and the ends of the staples bend and sealed with cement or painted with oil paints.
Depending on the depth of the well is changed and the height of its constituent modules: 400 to 1000 mm with Ø 800-1000 mm. wall Thickness can vary from 90 to 120 mm When using a metal reinforcement ring is made thinner from 50 to 90 mm.
Weight of each module is very large, so choose their size based on carrying capacity of the available funds or the presence of assistants. For example, reinforced concrete ring Ø 1000 mm and the same height and thickness of 50 mm and weighs 380 kg. For ease of installation and are preferable to elements with a smaller mass with a height of from 300 to 500 mm.
Reinforced concrete rings reinforced with steel reinforcing wire. For the vertical rods (they put 4 to 6 pieces per module) use wire Ø 8-12 mm, and for horizontal interlacing Ø 6-8 mm. Reinforcing rings have indented from each other by 50-80 mm. In each intersection of the frame is sealed with a soft (annealed) wire with a thickness of 2 mm.
