Description

The utility model 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 communications, various communication networks and sewer septic tanks, inspection, control, flushing, rotary, nodal wells, etc.

In the prior art, a plastic inspection drainage well is known, consisting of a bottom plate, a chute part, a working chamber, a floor plate, a manhole neck, brackets and built-in special fitting pipe connections (http://septikland.ru/drenazhnye-sistemy/ustrojstvo- drenazhnogo-kolodca.html, March 2015).

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

There are various reinforced concrete wells for sewers, including the following elements: bottom, wall and additional rings, neck, cover (http://vodakanazer.ru/kanalizaciya/kanalizacionnyj-kolodec/kolodcy-zhelezobetonnye.html, October 2016), as well as concrete viewing wells, consisting of the following main parts: a concrete base with a tray, a working chamber, a transition cone, a neck and a cast-iron manhole with a cover (http://gardenweb.ru/smotrovye-kolodtsy, November 2016). This source can be adopted as a prototype.

The disadvantages of these wells are the duration of the installation of pipelines and waterproofing the junctions of the sewer pipes with the walls of the well (ring), since at the place of installation of the well, punch holes to produce a hole contour for the interface, followed by its formation by hammering with a hammer or sledgehammer, assembly of formwork for concrete locks, pouring concrete locks with ready-mixed concrete and manual manufacture of a tray in the well, which together increases the labor expenditure on installation and the quality of interface node.

The technical problem to which the proposed utility model is aimed is to expand the arsenal of technical means of a well for discharging contaminated effluents, parameters whose characteristics provide an increase in operational characteristics.

The technical result achieved by the implementation of this utility model is to increase operational characteristics by reducing labor costs, reducing the time for assembling wells for discharging contaminated wastes, for constructing and installing wells, and also to increase the reliability of wells by providing better sealing (since it occurs in the factory), as a result of which the life of the well increases (durability).

The specified technical result is achieved in the well for the removal of contaminated effluents, containing a concrete ring with a concrete bottom, forming a working chamber, and for the formation of a kineta, the tray part monolithic with the bottom and inlet and outlet bell-shaped connections mounted in the concrete ring. Also, a well for discharging contaminated drains may contain a concrete floor, a neck and a hatch with a lid, while the ring is made of concrete of the M300 brand.

The ring and the bottom can be additionally reinforced with ribbed rods.

The tray part consists of a tray or channel in the form of a semicircle and a shelf extending from the tray or channel and adjacent to the wall of the concrete ring, while the tray or channel can have a curved shape, or a linear shape, or a kinet can be made with a tray unit, and the shelf tray part to improve the operational characteristics of the well can be performed with a slope towards the tray or channel.

The inlet and outlet socket connections are made of plastic, and can also be made corrugated.

The bottom and the overlap can be made integral.

The use of a concrete ring construction with a kineta, manufactured in the factory with a concrete tray part and bell-shaped joints, allows expanding the arsenal of concrete well technical means and increasing operational characteristics by reducing installation labor costs, increasing reliability and durability.

The claimed technical result is obtained by implementing the entire set of essential features reflected in an independent paragraph of the utility model formula.

The essence of the utility model is illustrated by drawings, where in FIG. 1 and 2 show a concrete well in section; in FIG. 3 is a top view of a concrete well; in FIG. 4-6 - embodiments of the kineta with a tray part and bell-shaped joints.

The well (made of M300 brand concrete) for the removal of contaminated effluents contains a ring 1 with a bottom 2, forming a working chamber 3, and for the formation of a kineta, a tray part 7 monolithic with a bottom 2 and a supply 4 and a discharge 5 plastic bell-shaped connections mounted in the ring 1, allowing connecting through the rubber sealing ring 9 (cuff) of the pipe 6, for example, the Pragma pipe.

Ring 1 and bottom 2 can be reinforced with ribbed rods.

The tray part 3 is made with a tray 10 / channel in the form of a semicircle of curvilinear or linear shape and a shelf 8, extending from the tray 10 / channel and adjacent to the wall of the ring 1 and having a slope towards the tray 10 / channel.

A well for the discharge of contaminated effluents is made as follows.

The ring is made by the standard method of pouring commodity concrete into a removable metal formwork on a vibrating table or using a mounted vibrator. For the production of the tray part, a foam mold is used, which is placed inside the metal mold so that after it is removed from the kineta, a completely finished bell connection and the tray part are obtained. Polyfoam in this case plays the role of a disposable form, which is lost after manufacture. In the walls and the bottom of the ring (kineta), a reinforcing metal mesh can be mounted to strengthen the walls and bottom.

After solidification, the ring is taken out of the formwork, the foam and parts of concrete that violate the kinet's nominal pass are removed. Further, in a standard way - by pouring ready-mixed concrete into a removable metal formwork, the second concrete ring of the well’s working chamber, overlap and neck are made.

At the installation site of the well, dig a pit, prepare the foundation of the pit (sand or concrete, determined by the project), and then put in it a factory-made concrete ring, the kinet of which is already made with the necessary, depending on the purpose and function of the well, tray part and bell-shaped compounds, which are then connected to the stop, for example, from two to four sides into the kineta, through the rubber sealing ring of the pipe (inlet and outlet). Since the connection is completely tight, you do not need to modify anything, you can immediately assemble the upper part of the well (the second ring of the working chamber of the well, overlap, neck, hatch with a cover), install the ladder and make the well waterproof.

It is also possible to provide a transition to any other system of corrugated or smooth pipes / pipelines. Using this technical solution, it is possible to reduce the construction time of sewer networks by several times (up to three to five hours). It will also help installers to quickly and efficiently work in the winter. In addition, as an additive to concrete, you can use a special crystallizing mixture that increases the water resistance of concrete.
