Rings and covers of wells
Rings and lids of wells - are reinforced concrete structures for the construction of wells for various purposes.
They are used for the construction of wells of all kinds and purposes: sewage systems, water supply systems, gas pipelines, inspection, network, drainage and private water wells, wastewater treatment facilities. Can be used for heat and power distribution.
Rings of wells are produced from heavy concrete of class C12 / 15, frost resistance F50, water resistance W2 in accordance with STB1077-97. This gives the product a high strength and frost resistance. The technology of production is constantly being improved. For production, the mold is placed on a flat surface. Then reinforce, which increases the strength of the structure, and pour concrete solution. After that, the mixture is rammed, by vibration method. Concrete solution is compacted, which makes the product more durable. This production technology allows producing frost-resistant products.
When constructing the wells, it is necessary to have bottoms, slabs (cover of the well), rings of wells. For hatches in such slabs a special opening is provided.
