Abstract

A casing ring, which includes a cylindrical body made of a composition of materials, which includes a binder - Portland cement or slag Portland cement, plasticizing material, filler, reinforcing material, water and sand, characterized in that the cylindrical body is made of a material composition which additionally includes a light inert filler as a filler - expanded polystyrene, reinforcing material - fiber, plasticizing material - polyvinyl acetate in the composition with plasticizer - C3 or GLENIUM-51.

Description

The utility model relates to building structures and can be used for the manufacture of inspection wells of sewer, water and gas networks, and can also be used in the oil and gas industry.

The ring according to GOST8020-90 "Concrete and reinforced concrete structures for the inspection wells of sewer, water and gas networks" is known. These designs are used as the main elements from which wells for various purposes are built. Different well rings are used depending on the purpose of the well. Thanks to the well rings, a well trunk is formed. As a material for the manufacture of well rings using steel reinforcing wire, cement, sand, gravel, water.

The disadvantages of the analogue include low physical and mechanical characteristics of the ring, low reliability, quality, durability, high cost of manufacturing rings and limited functionality.

For the prototype, well-known well rings can be taken to improve the quality of which S-3 superplasticizer, silica fume, cm (http://www.stroybil.ru/index.php?x=bi11011) are added to the material. The disadvantages also include low physical and mechanical characteristics of the ring, low reliability, quality, durability, high cost of manufacturing rings and limited functionality.

The objective of the proposed utility model is:

production of casing rings in those places where they are supposed to be used; ring weight reduction; increase the physical and mechanical properties of the finished product, by increasing the frost resistance of the ring, heat transfer resistance, increasing corrosion resistance; as well as enhanced functionality.

The problem is solved due to the fact that the casing ring includes a cylindrical body made of a composition of materials, which includes: cementitious material - Portland cement or slag Portland cement; plasticizing material, filler, reinforcing material, water and sand, and the cylindrical body is made of a composition of materials, which is additionally included as: filler - a light inert filler-expanded polystyrene; reinforcing material - fiber, plasticizing material - polyvinyl acetate in the composition with a plasticizer - C3 or GLENIUM-51.

The composition of the material from which the casing rings are made includes:

polystyrene foam is a light inert filler, granular foamed polystyrene (PVG), which represents the product of one- or multi-stage foaming of suspension foaming polystyrene (OST 301-05-202-92E) that meets the requirements of this standard. It is also possible to use polystyrene foam aggregate obtained by crushing waste from polystyrene foam products (subject to compliance with environmental safety requirements). The brand in bulk density and size can vary widely (usually 8-100), depending on the type and purpose of the products. The technical result from the use of expanded polystyrene is weight reduction, frost resistance, heat transfer resistance, increased corrosion resistance.

As a binder, Portland cement or slag Portland cement is used, which meet the requirements of GOST 10178, which, with the same strength characteristics, reduce the weight of the ring.

The plasticizing materials used are S-3 plasticizer and polyvinyl acetate, air-entraining hardening-regulating materials or GLENIUM-51 hyperplasticizer and polyvilapstat, which helps maintain a constant plasticizing effect with a significant reduction in the dosage of water and increase the durability of concrete.

Microfiber building fiber reinforcing BCM from granules of C3H3 poppropylene. The length of the fibers is 6-20 mm, depending on the purpose of the product. It is possible to use fibers of steel, basalt, acrylic and alkali-resistant glass. The use of fiber allows you to reduce the weight of the finished product, its cost.

Water for mixing polystyrene-fiber-concrete mixture must comply with GOST 23732.

The casing ring is made as follows. The mold for the manufacture of the ring is filled with a pre-mixed composition of the composition of materials: binder, sand, water, S-3 or GLENIUM-51 plasticizer, polyvinyl acetate, fiber, expanded polystyrene and compacted, then additionally fill the form with the mixed composition and compact again, these operations are repeated until complete filling out the form. After being removed from the mold, the ring is delivered to the place of use.

A utility model made from the proposed composition of materials is 5-6 times lighter than known structures, and is also not afraid of contact with water, soil and bacteria.

Claims (1)

A casing ring, which includes a cylindrical body made of a composition of materials, which includes a binder - Portland cement or slag Portland cement, plasticizing material, filler, reinforcing material, water and sand, characterized in that the cylindrical body is made of a material composition which additionally includes a light inert filler as a filler - expanded polystyrene, reinforcing material - fiber, plasticizing material - polyvinyl acetate in the composition with plasticizer - C3 or GLENIUM-51.
