Abstract

FIELD: building.

SUBSTANCE: invention relates to underground structures, in particular, to a structure of a circular concrete well, and can be used in building and erection of engineering and water supply utility systems, various communication networks and sewage septic tanks, inspection, control, flushing, rotary, intersection wells, etc. The prefabricated reinforced concrete well comprises a concrete bottom 1, installed whereon vertically on top of each other are reinforced concrete rings 2, 3, 4 (the amount of rings can be both greater and fewer than indicated in the drawing), covered with a lid 5, installed whereon is a neck 6 covered with a lid 7, waterproofing elements 8 made in the form of a set of "Super Fix" tapes (the tapes are not shown in the drawing), laid on the outer surface of the rings except for the areas not covered with waterproofing tapes. For this purpose, adjacent sections of the waterproofing tapes in elements 8 must be partially overlapping.

EFFECT: facilitated assembly with simplified delivery of waterproofing elements.

Description

The invention relates to underground structures, in particular to the construction of a round concrete well, and can be used in the construction and erection of engineering and water supply lines, various communication networks and septic tanks, observation, control, flushing, rotary, nodal wells, etc.

From the prior art, a plastic inspection drainage well is known, consisting of a bottom plate, a tray part, a working chamber, a ceiling plate, a hatch neck, brackets and built-in special fitting connections with pipes (http://septikland.ru/drenazhnye-sistemy/ustrojstvo- drenazhnogo-kolodca.html. March 2015).

This type of well is not protected from floating to the surface in the spring-autumn period, as well as during installation in water-saturated soils due to its own weight.

A prefabricated reinforced concrete well is known, containing a concrete bottom, on which reinforced concrete rings are installed vertically on top of each other, closed with a lid, on which a neck with a cover covering it is installed (see: https://yandex.ru/images/search?text=waterpipe% 20well% 20type% 20project% 20901-09-11.84 & stype = image & lr = 46 & source = wiz Water supply wells. Typical project 901-09-11).

The disadvantage of this prefabricated reinforced concrete well is: a low degree of waterproofing - water can seep through the concrete rings and their joints without any particular problems. This means that groundwater can enter the sewerage system and wastewater into the ground. This reduces the service life of precast concrete wells.

The closest in technical essence to the proposed one is a prefabricated reinforced concrete well containing a concrete bottom, on which reinforced concrete rings are installed vertically on top of each other, closed with a lid, on which a neck with a cover is installed, additionally contains a general well liner, which is a hollow cylindrical body with a bottom , in which the elements of the well are located: the bottom, reinforced concrete rings, a cover covering the reinforced concrete rings (see patent for a useful model RU No. 196365, M. CL .: E03F 5/02, 2020).

The disadvantage of this prefabricated reinforced concrete well: the complexity of its installation, as well as the complexity of delivery of the liner.

The technical result of the proposed invention simplifies installation while simplifying the delivery of waterproofing elements.

The set technical result is achieved by the fact that in a prefabricated reinforced concrete well containing a concrete bottom, on which reinforced concrete rings are installed vertically on top of each other, closed with a lid, on which a neck with a cover is installed, a waterproofing element, a waterproofing element is made in the form of a set of tapes "Super Fix ”, applied to the outer surface of the well with the exception of places not covered with a waterproofing element.

"Super Fix" tape is a special composition that has a triple thickness and is formed by super-strong glue, which allows it to instantly adhere to any surface and form a tight connection, closing even the most severe leaks, cuts, breaks, etc. They are easily fixed even on any flat surface (plastic, metal, tiles, wood, ceramics, brick, concrete, glass, tarpaulin, etc.) and forms a tight connection. The Super Fix tape will glue wet surfaces even under water! (see Arguments and facts №12 (2053), p. 24).

The drawing schematically shows the proposed reinforced concrete well with a waterproofing element superimposed on the outside of the well.

A prefabricated reinforced concrete well contains a concrete bottom 1, on which reinforced concrete rings 2, 3, 4 are installed vertically on top of each other (the number of rings can be more or less shown in the drawing), closed by a cover 5, on which a neck 6 is installed with a closing cover 7, waterproofing elements 8 (position 8 denotes a waterproofing element applied to the outer side of the well), made in the form of a set of Super Fix tapes (tapes not shown in the drawing) applied to the outer surface of the well with the exception of places not covered with waterproofing tapes. For this, the adjacent sections of the waterproofing tapes in the elements 8 must partially overlap each other. The ring 2 can be made in one piece with the bottom 1. The pipe entries into the ring 2 are sealed by known methods. In this case, the walls covered with a set of tapes must be pre-cleaned from dust and dirt.

To increase the reliability of waterproofing, waterproofing can be applied in a similar way to the outer surface of the rings, as shown in the drawing.

Improving the reliability of work with a simultaneous increase in the service life due to almost 100% waterproofing is the advantage and advantage of the proposed technical solution in comparison with the prototype.

Claims (1)
