Cable well: design features, functions, models and dimensions

The cable well today has found its wide distribution. It is actively used in the process of construction and if necessary laying cable systems. Classify the data of the product can be on two grounds. The first version is designed for cable communication, while the other is for power supply. At the heart of such products can lie concrete reinforced with reinforcement, or plastic.

Need to use

With the help of these devices, repairs, installation and maintenance of electricity supply networks can be carried out without opening the underground channels. For the production of wells, different materials are used, however, reinforced concrete structures last longer than others, because the material has high strength, inertia and durability.

Features of constructions

The cable well is available in different versions. If we are talking about models for building telephone communications, then such products can vary in size. Manufacturers they are allocated an alphanumeric designation. Among other things, the wells can be subdivided depending on the loads that will be provided to them during the operation.

On sale you can find light and heavy wells. In the latter case, the products are used for laying under the carriageway, whereas in the first case they are installed under the zone for pedestrians. All models have the appropriate marking, this factor facilitates the choice for the buyer and allows eliminating unnecessary costs. If we talk about the design features of the model KKS-1, it can be argued that it is installed not only under the footpaths, but also under the carriageway. There are data from the top of the article and the reinforced concrete slab, the dimensions of which are 1450 x 1100 x 80 mm. Elements between themselves are connected by electric welding along the contour of loops, and the niches are poured with concrete.

Considering the KKS-2 model, you will understand that it has an octagonal form and consists of two parts, namely, the top and bottom. The latter has half of the side walls and the bottom, while the upper part has half the side walls and the upper overlap. In the upper part there are round holes, above which there is a ring of a hatch and a hatch of cast iron. These products are completed with threaded brushes and steel brackets, which are fastened with breadcrumbs.

Wells, to the letter designation of which the numbers 3, 4 or 5 are added, are completed with steel truncated brackets. They join the ruffs without thread. On sale, you can also find universal wells that have four niches and are completed with brackets or anchor bolts. Telephone wells are used to mount the cable at a convenient angle.

Basic functions and types of cable wells

The cable well can be made of plastic, in this case it is used for pulling, installing, repairing and inspecting communication cables. Installation of these products is carried out in the ground, which can not adversely affect the concrete. The main varieties are KKS-2 and KKS-5, which have an octagonal form and consist of two halves. This was discussed above.

Such products in the ceiling have holes that are complemented by a hatch. KKS-1 is used for installation on the roadway and roads. These structures can also be used on pedestrian paths. It should be borne in mind that the effort can be 10 tons, but in the case of the roadway this value increases to 80 tons.

On sale you can find a cable well, which is intended for shallow burial, it is located under the road, on lawns and sidewalks. If you compare with other products, in this case the coupling is assembled from the outside, and not in the shaft. And then, together with the cables, it sinks to the bottom of the structure. Seams are absent, therefore ground waters can not negatively influence materials and damage them. The term of use of these products is much longer.

Cable communication wells are made of concrete M-200. They are designed for the load that is on them on the roadway. Protects the product from damage reinforced ring, which is located in the upper zone. From below there is a pit, which serves to drain excess water. From the elements of the well, we should also highlight ruffs, which strengthen the brackets for cables and equipment. There are also earrings in the system, which are used to fasten the unit while laying the cable.

Models and sizes of cable pits

Wells for cable ducts, as mentioned above, are produced under different brands, each of which has its own dimensions and cost. For example, the model KKS-0 has a weight of 0.9 tons and dimensions equal to 1480 x 900 x 940 mm. Well KKS -1 weighs a little more - 1.1 tons, the dimensions also increase and amount to 1400 x 1060 x 800 mm. The KKS-4 well will weigh 4 tons, and its dimensions will be 2400 x 1240 x 2020 mm. On sale you can find a well with the following marking: STK, which weighs 3.5 tons and has dimensions equal to 2450 x 1300 x 2010 mm.

Cost of cable wells

If you are interested in cable wells, the price you should also be interesting. The cost of these products depends on the size. For example, if the inner diameter is 800 mm and the height is 1000 mm with a wall thickness of 25 mm, then this design will cost the consumer 22,000 rubles. If the internal diameter increases to 900 mm, and the remaining parameters remain the same, the cost will be equal to 24,000 rubles. With an increase in the inner diameter to a mark of 1100 mm, you will have to pay 34,000 rubles. The height of the structure will be 1,250 mm, but the wall thickness remains the same.

Conclusion

The main types of cable wells have been described above, but all of them are divided into heavy and light. Such cable systems have advantages, among them: tightness, excellent durability, long service life, resistance to low temperatures, the possibility of carrying out work under difficult conditions, and also ease of transportation and storage.
