The housing 1 is provided with four external elongated tides-protrusions 5, 6, 7, and 8. The tides-protrusions 5 and 6 are adjacent to the neck 2 of the housing 1, and the tides-protrusions 7 and 8 are placed on the flattened supporting surface of the housing .

Cable entries 4 are placed at least in two groups, symmetrically in the flattening zones 10, 11, 12 and 13 on the outer surface of the housing 1. Cable entries 4 are made in the form of sealed, muffled in the supplied state, recesses. The elongated tides-protrusions 5, 6, 7 and 8 are made with grooves 15 on the inner surface of the housing 1.

The volume of the housing 1 and the diameter of the neck 2 are selected from the conditions of creation in. cavity body working area.

The cover 3 is threaded and provided with an annular seal. The housing 1 with the neck 2 and the cover 3 are made, for example, of plastic, preferably polyethylene, resistant to thermo-oxidative aging under the influence of soil and groundwater and other external factors. The housing 1 with the neck 2 and the cover 3 are made by rotational molding from the melt.

The collapsible frame 16 is made in the form of interconnected closed frames 17, 18, 19 and 20, assembled from a set of prefabricated rod elements 21. A part of the prefabricated rod elements 21 from the set is made in the form of rounded corner elements 22. The ends of the rod elements 21, 22 are rigidly interconnected by any known method, for example, by fixing nodes. Parts of the collapsible frame 16 assembled from the prefabricated core elements 21 including the rounded corner elements 22 are placed in the grooves 15 of the outer elongated tides-protrusions 5, 6, 7 and 8 on the inner surface of the housing 1. The prefabricated core elements of the set 21, 22 are made for example, galvanized steel, stainless steel, aluminum, alloys containing aluminum, from a metal pipe of any section, either T-shaped, or H-shaped, or U-shaped, or C-shaped metal profile. Flattening zones 10, 11, 12, 13 on the outer surface of the housing 1 with groups of cable entries 4 are made in the form of a circle 23.

Closed frames 17, 18, 19 and 20 of the collapsible frame 16 are mounted with standard mounting devices, for example, brackets and / or cable consoles.

The frame 1 is assembled frame 16 in the form of interconnected closed frames 17, 18, 19 and 20, assembled from a set of prefabricated core elements 21 with the inclusion of rounded corner elements 22. Parts of a collapsible frame 16, assembled from prefabricated core elements 21 with the inclusion rounded corner elements 22 are placed in the grooves 15 of the outer elongated tides-protrusions 5, 6, 7 and 8 on the inner surface of the housing 1.

The well in the assembled form lowers to the bottom of the pit and is oriented in such a way that the direction of the cable entries 4 coincides with the direction of the designed lines for laying the pipes of the cable pipeline. The well is placed in a pit under a base plate installed at the level of the backfill.

The design of the well described above improves the strength characteristics of the well, it is possible to quickly build complex configurations of communication sewerage, the conditions for monitoring, installation and maintenance of cable connections are improved due to the creation of a working zone inside the housing 1.

The presence of several cable entries 4 on the sides of the housing 1 allows you to use the well as a passage, angular and / or branching. Unused cable entries 4 are stored in the delivery state, i.e. muffled, and can not cause a violation of the tightness and the penetration of groundwater.

The housing 1 is tightly closed by a cover 3. Between the neck 2 and the cover 3 an o-ring is placed. The cover 3 is screwed on with a socket wrench, the holes 9 are used for installation. The small weight of the well allows reducing transportation costs to the installation site. Loading and unloading, installation and orientation along the cable line of the wells can be carried out without the use of lifting mechanisms.

The use of polyethylene as the material of the body 1 and cover 3 allows you to make the body 1 of the well monolithic, sealed, resistant to temperature influences in the range of ± 50 ° C.

A monolithic plastic well has high mechanical strength, while it is possible to transport the well by any means of transport and to inaccessible areas on any roads.

The presence of an internal collapsible frame allows you to: mount the frame, both in the factory and in the field; provides rigidity for the entire period of operation of the well; allows you to fasten, lay, install cables, couplings and equipment inside the well of various design configurations.

The proposed well is resistant to aggressive environments, to temperature extremes, which makes its service life very high.

The presence on the side surfaces of the housing 1 of the well of structural pipes (inputs) 4 for pipes allows tracing the cable line with high accuracy.

The design of the housing 1 and the outlet neck 3 are made in such a way that a base plate with a standard hatch and a cover can be installed over the well.

The cable entries are made in the initial (delivery) state, plugged with a blind hole, which ensures complete tightness and the ability to use only the necessary cable entries for the inputs for various types of pipes (for the input of which the required hole is drilled of the required diameter, and the input end of the tube is sealed outside the well with heat shrinkable tube).

Cable lines in the case do not require routine maintenance for a long time. During the operation of the cable network, the well does not allow water and corrosive media to be exposed to the cables and retains the ability to check the status of connections and cables directly through the housing working area.
