The cable well has found its wide distribution today. It is actively used in the process of construction and, if necessary, laying cable systems. There are two ways to classify these products. The first variety is designed for cable communication, while the other is for power supply. Such products may be based on reinforced concrete or plastic.
Need to use
Using these devices, repair work, installation and maintenance of electricity supply networks can be carried out without opening the underground channels. Different materials are used for the manufacture of wells, however, reinforced concrete structures last longer than others, because the material has high strength, inertness and durability.
Design Features
The cable well is available in various versions. If we are talking about models for laying telephone communications, then such products may vary in size. Manufacturers stand out with an alphanumeric designation. Among other things, wells can be divided depending on the loads that will be exerted on them during operation.
On sale you can find light and heavy wells. In the latter case, the products are used for laying under the carriageway, while in the first they are installed under the pedestrian area. All models are marked accordingly, this factor facilitates the choice for the buyer and eliminates unnecessary costs. If we talk about the design features of the KKS-1 model, it can be argued that it is installed not only under pedestrian walkways, but also under the roadway. These products consist of the upper part and the reinforced concrete slab, the dimensions of which are 1450 x 1100 x 80 mm. The elements are interconnected by electric welding along the loop, and niches are poured with concrete.
Considering the KKS-2 model, you will understand that it has an octagonal shape and consists of two parts, namely, the upper and lower. The latter has half of the side walls and the bottom, while the upper part has half of the side walls and the upper ceiling. In the upper part there are round holes over which the hatch ring and cast iron hatch are installed. These products are completed with ruffs with thread and steel brackets, which are fastened with crackers.
Wells, to the letter designation of which the numbers 3, 4 or 5 are added, are equipped with shortened steel brackets. They join ruffs without thread. On sale you can also find universal wells, which have four niches and are equipped with brackets or anchor bolts. Telephone wells are used to mount the cable at a convenient angle for this.
The main functions and varieties of cable wells
A cable well can be made of plastic, in which case it is used for pulling, installing, repairing and checking communications cables. Installation of these products is carried out in soil, which cannot adversely affect concrete. The main species are considered KKS-2 and KKS-5, which have an octagonal shape and consist of two halves. This was discussed above.
Such products in the ceiling have openings that are complemented by a hatch. KKS-1 is used for installation on the carriageway and roads. These structures can also be used on footpaths. It should be borne in mind that the force 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 deepening, it is located under the road, on lawns and sidewalks. If we compare with other products, then in this case the clutch is assembled outside, and not in the shaft. And then, together with the cables, it sinks to the bottom of the structure. There are no seams, so groundwater cannot adversely affect materials and damage them. The term of use of these products is much longer.
Communication cable wells are made of concrete grade M-200. They are designed for the load that is placed on them on the roadway. The reinforced ring, which is located in the upper zone, protects the product from damage. Below there is a pit that serves to drain excess water. From the elements of the well, ruffs should also be distinguished, which strengthen the brackets for cables and equipment. There are also earrings in the system that are used to secure the unit during cable laying.
Models and sizes of cable wells
Wells for cable ducts, as mentioned above, are produced under different brands, each of which has its own size and cost. For example, the KKS-0 model 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 well of the KKS-4 brand 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 markings: STK, which weighs 3.5 tons and has dimensions equal to 2450 x 1300 x 2010 mm.
The cost of cable wells
If you are interested in cable wells, the price should also be interesting to you. 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 such a design will cost the consumer 22,000 rubles. If the inner diameter increases to 900 mm, and the remaining parameters remain the same, then the cost will be equal to 24,000 rubles. With an increase in internal diameter to 1100 mm, you will have to pay 34,000 rubles. In this case, the height of the structure will be 1250 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, including: tightness, excellent strength, long service life, resistance to low temperatures, the ability to work in difficult conditions, as well as ease of transportation and storage.
