Rings concrete - that is fraught with this part of the well ?

concrete rings - the appointment and classification

manufacture of such items is carried out with the use of high-quality concrete and the reinforcing mesh scaffolds.Dimensions of basic rings are normalized standards.Typical concrete products for the wells are divided into three groups: small, medium and large.

Accordingly, a group of small rings include ring meter inside diameter, wall thickness and a height of 16 - 90 centimeters.The weight of the ring is six hundred kilograms.Polutorametrovy ring of the same height, weighing one ton average group size form and fall into the category of large diameter rings polutoratonnye two meters.

concrete manholes rings are made of high-quality concrete and construction are widely used.In addition to the above examples, the rings are in demand in the construction of wells in a private home ownership.The kits above group sizes of rings include the cover and the base (bottom) designs, appropriate diameters and are binding on all members of the well design.

If the purpose is to create a ring of strong walls of the well (why they are often called the wall), the appointment of reasons - preventing siltation well.When necessary to ensure closing of the protruding above ground level of the wall of the ring, apply standard design covers wells.According to the specified size of the ring can also be divided into classes: A - up to a meter in diameter and more than a meter - B. First often used for the installation of wells.

manufacturing principles in the manufacture of sections of special forms used for concrete rings.This kind of formwork sets the size of the outer and inner diameters of the future element.In the space of a special reinforcing mesh is placed and filled with mortar between them.

For better seal shape exposed vibrated, pressed concrete.As a result, the product receives high strength and quality to fulfill its function, maintaining substantial soil load.special bracket can be fitted in the manufacture of rings, called moves.

Industrial concrete rings Pit may have special grooved locks.This protrusions at the bottom of the rings and their corresponding grooves in the counter top.This structural feature is preferred becauseIt allows for reliable and well sealed fixing barrel, avoiding the displacement of constituent rings.Also

wall rings of standard sizes is available wall transoms, which differ in height and used when necessary structures protruding above ground portion of the well.It distinguishes such transoms smaller height as compared with conventional rings.

concrete rings Pit - make yourself

If necessary, for example, products with a diameter less than the model, it can be concrete rings with their hands , sizes soaking according to the characteristics of a particular well under construction.As for other concrete works, the composition ratio of the mixture is determined by weight, or (less often) in terms of its components: gravel (or gravel), sand and cement.

unit of reference is always the amount of cement.Water-cement ratio is important: for well rings it is 0.5 to 0.7 part of cement.In turn, the sand taken from two to two and a half parts of cement.Granite gravel - from three to four parts, respectively.These ratios provide a maximum density of the resulting concrete.

for manufacturing concrete work starts with the mixing of sand and cement, and then water is added and then thoroughly mixed.Further, the solution was poured into water pre-soaked gravel.Panning is conducted after a thorough mixing of concrete.Each layer in the ring it up compacted cement milk.Quality seals and further curing mold directly determine the strength of the entire product.
