Ring for wells - how to choose?

A well can be built from several materials:

• Natural or artificial stone.

• Wood (external cladding only).

• Plastic (also only the outer part, located above the ground).

• Concrete and reinforced concrete.

• Ceramic brick.

The two most reliable materials are stone and Concrete rings. However, the stone is expensive, so it is not suitable for everyone. But rings for wells are 3-4 times cheaper. But they have all the advantages of brick or natural stone:

• Long service life - from 50 to 100 years.

• High strength.

• Resistance to deformations.

  
  
  

• Resistance to temperature fluctuations, high humidity, constant contact with water and other liquids.

• Resistance to chemical substances.

• Easy installation.

• High frost resistance.

• Low coefficient of water absorption - about 1-2%.

  
  
  

• Exact geometry of the dimensions.

• Resistance to the formation of fungus and mold, as well as to rotting processes.

Reinforced concrete rings for wells are a great solution for 2 reasons:

• Steel reinforcement inside the rings increases the strength and bearing capacity of the material.

• Concrete protects steel reinforcement from contact with the external environment, especially with water and steam. Therefore, the armature is subject to terrible corrosion.

And how to choose a ring for wells? You need to pay attention to 2 criteria:

• Class of concrete.

• Dimensions.

As a rule, all rings for wells are made of concrete class B15. Such a product can withstand a compressive load of up to 15 MPa, which is more than enough for a well of any size.

Please note that certain covers correspond to the diameter of the rings. When buying a well cover, pay attention to the marking and passport data. It is very important that the cover and the ring coincide in diameter.

In Trivita's online store, you can choose any of the 9 standard sizes of the lid https://trivita.ua/ru/zhelezobetonnye-izdelija-zhbi/kolca-kryshki-dnisha:

• KSE-10-3 (total length – 1160 mm, height – 300 mm).

• KSE-10-6 (1160x600 mm).

• KSE-10-9 (1160x900 mm).

• KSE-15-6 (1680x600 mm).

• KSE-15-9 (1680x900 mm).

• CS 10.6 (1160x890 mm).

• CS 10.9 C (1160x890 mm).

• CS 15.6 (1680x890 mm).

• CS 20.9 (2200x890 mm).

Pay attention to the marking. It indicates the type of ring, and then the diameter without taking into account the thickness of the walls (that is, not the diameter of the ring, but the diameter of the hole). The number indicates the diameter in decimeters. For example, the KSE-15-6 ring has a hole diameter of 1500 mm, or 15 dm, and a total length of 1680 mm. The second number indicates the height in decimeters - 900 mm (9 dm).
