The technical result consists in increasing the convenience of assembling the well and installing communications in it.

Description

The utility model relates to the infrastructure of underground communications, in particular to underground structures, such as manholes, manholes, manholes and other devices, and is intended primarily for the installation of cable lines and their inspection.

A well is known that contains a number of identical sections made with the possibility of joining together, each of which is formed by an annular wall having openings of different widths from different edges, the wall of the section having a stepped surface, with ribs formed at least on one stage of the section stiffness (RU 15899 U1, IPC E03F 5/02, publ. 20.11.2000).

The closest analogue is a cable duct that contains a monolithic casing, a neck of the casing, and cable entries from at least two sides of the casing made of plastic, the casing is equipped with stiffening ribs made along with it, the volume of the casing and the diameter of the neck selected from the condition of providing the possibility of placing a person inside the housing (RU 86635 U1, IPC E04H 5/06, published on 09/10/2009).

Among the shortcomings of the known wells, the low convenience of assembling and installing communications due to the lack of pockets inside the sections for mounting various fittings, as well as the lack of the ability to install the section of the well on an existing cable channel (pipe) without breaking it, should be mentioned.

The technical result of the claimed well of cable ducts is to increase the convenience of its assembly and installation of communications by performing positioning and sealing sections of the well using a groove-spike type connection, using pockets on the inner walls of the well, installing cable ducts in a non-heating way (using sealing cuffs) and the possibility of installing it on an existing cable channel (pipe) without breaking it, due to the different profile of the walls of its sections.

The well of cable ducts contains a housing having a bottom, a cover, stiffeners and openings (cable channels) for the cable. The technical result is achieved due to the fact that the casing is made of a number of sections mounted one on top of the other and having a groove and a reciprocal spike at the interface, each section of the well formed by four walls made in the form of a hollow hollow profile with cut out holes for cuffs, serving for the installation of cable channels when laying the cable. Moreover, in the locations of the holes for the cable channel, the outer wall of the hollow profile is concave and has the shape of a semi-oval, and when combining two sections of the well, the concave outer wall of one section coincides with the concave outer wall of the other section, forming an oval shape, while on the inner walls Well installed pockets for mounting fittings. Well sections are fastened together with studs, cap nuts, and self-locking nuts using lock washers made of stainless steel or polymeric materials (high pressure polycarbonate).

The utility model is illustrated in the drawing (Figure 1). The figure 1 shows the section of the well, in which the position 1 marked groove (spike is not shown); Pos.2 - stiffeners; pos.3 - pockets for fastening reinforcement; Pos.4 - places for holes on the outer concave wall of the section.

The lid and bottom are made using the technology of sand-plastic molding under high pressure, and the sections are made of plastic.

The proposed design of the well allows the use of various options for covers:

- composite (tight) - is performed by the method of sand-plastic molding under high pressure;

- concrete, with constipation in a metal harness rigidly fixed to the upper element of the well;

- cast iron, with constipation in a metal harness rigidly fixed to the upper element of the well;

- aluminum, with a glued rubber mat in a metal harness rigidly fixed to the upper element of the well.

Claims (4)

1. A well of cable ducts comprising a housing having a bottom, a cover, stiffeners and cable holes, characterized in that the housing is made up of a number of sections mounted one on top of the other and having a groove and a reciprocal spike in the interface, each section being formed four walls made in the form of a hollow hollow profile with cut out holes for cuffs, used for mounting cable channels when laying the cable, and in the locations of the holes for the cable channel the external wall of the hollow profile made concave and has the shape of a semi-oval, and when combining two sections of the well, the concave outer wall of one section coincides with the concave outer wall of the other section, forming an oval shape, while pockets for mounting reinforcement are installed on the inner walls of the well. 2. The well of cable ducts according to claim 1, characterized in that the securing of the sections of the well to each other is performed using studs, cap nuts and self-locking nuts using lock washers made of stainless steel or polymeric materials. 3.
