Communication well kks 3 10 standard drawing. Types and features of installation of cable wells. Features of the design and material used

Cable wells communications KKS 3-80 or, as they are also called, telephone wells are part of communication, cable duct, which exists for pulling and servicing communication cables, for example, GTS or Internet. Cable wells vary in size and modification. They are made of reinforced concrete, this strength is very important and is explained by the fact that they need to withstand the load of soil pressure. A load of 80 indicates that this cable well can be located under roadway and highways. Communication wells are made from heavy concrete. Thanks to this, they can reliably accommodate equipment that allows automatic mode regulate the distribution of Internet traffic. This modern look communications need reliable protection from environmental conditions and providing access only when necessary, without the penetration of unauthorized persons.

Each telephone well consists of upper and lower blocks, which are joined directly on the construction site using welding. Inlet, round shape, located on top, consists of a reinforced concrete ring and a cast iron hatch. Some cable wells can be equipped with nuts, brackets and brushes, then they are marked with the abbreviation “KKS 3-80 GEK”. The communication cable is attached to the brackets. The number of brackets and consoles depends on what type of KKS well. The brackets are made of steel and are equipped anchor bolts and nuts. This well should be covered with a cast iron hatch of the “T” type - heavy. Transportation of KKS cable wells is carried out by car. The car must be open top. During transportation, wells cannot be stacked on top of each other. Installation of the KKS-3 telephone well should be carried out in a pre-prepared pit. The ground must be leveled before this.

All seams must be treated well, coated cement mortar, so that the well is sealed so that moisture does not get into the cable connections. In order for the cement to “grab” better, each of the reinforced concrete parts is treated with water, simply moistened. To protect communication cables inside wells, special casings and cable channels are used. Usually this plastic pipes, which run underground and branch out in telephone wells. Such wells are buried about a meter into the ground. In such a well there must be access to all the elements that are installed inside.

If an inspection is being carried out on the line, then access should be easy and quick thanks to a simple shutter system. There is enough space in such a well for signalmen to carry out all the necessary checks and work. If brushes and brackets are not provided, the customer can select the ones he needs. The weight of cable wells depends on its index.

Considering that environment, in this case the soil, should not be aggressive to materials such as concrete. In my own way technical purpose wells are stationary, walk-through, corner and branch wells KKSr 3-80. If you count in the direction from the shaft, the stationary communication well is the first one, used to enter cables. Walkways are constructed on straight sections of extended canals. Corner or branching wells are installed where it is necessary to turn or branch the cable channel.

In the age of communication technologies in village and city infrastructure, it is impossible to do without them. They allow you to implement communications in the most convenient way. In some cases, it is technically impossible to install a reinforced concrete telephone well, then their plastic counterparts come to replace them, which, of course, are not as durable and strong, but are also in demand because they are more cheap material, easier to operate and install. But most builders still give preference to traditional materials; I prefer not to skimp on quality. The service life of such cable wells is practically unlimited; it is guaranteed to be about seventy years.

Cable wells (CC) are used in the construction of electrical and telecommunication networks as inspection tanks, inside of which coupling connections are located electric cable. The well provides free access to the network nodes, which allows for prompt maintenance and repair.

This article presents cable wells. We will look at their design, sizes and varieties, and also give instructions for installing such structures.

1 Reinforced concrete wells - features of production and application

Cable wells are components of prefabricated well structures, which are produced in accordance with the provisions of TU No. 45.1418-83. This standard contains requirements for the specification of elements, their typical drawings, features of production, storage and delivery technology.

All products have standard markings, consisting of designations of the type of structure, its size and method of reinforcement. Optionally, important design features, the mass of one section and the date of its production.

Reinforced concrete KK are prefabricated products consisting of two parts - upper and lower, each of which consists of horizontal ceilings (there is a hatch in the form of a round hole on the upper one) and half of the side walls. The holes for the hatch, regardless of the size of the well, are always made with a diameter of 600 mm.

On the walls of the structure, mounting earrings are provided (used to secure blocks when pulling cables) and brushes (for attaching brackets for equipment).

Depending on the shape, CCs are classified into round, square and prismatic. Depending on the location of installation, structures are divided into three types:

stationary;
corner;
checkpoints.

KK stationary versions are used most often - this is the main type of wells for installing cable and utility networks, while designs of corner and pass-through configurations are used in individual cases, when it is necessary to lay networks on difficult terrain, with multiple turns within the same network, etc.

Data reinforced concrete products are produced in a factory using bench or aggregate-flow methods. Most often, the bench production method is used, the essence of which is to pour concrete into special matrices that form the final contours of the products.

For the production of CC, concrete corresponding to strength class B22.5 or grade M300 is used. It is permissible to use exclusively fine-grained inert fillers, the use of which makes it possible to achieve the specified frost resistance and water resistance of products.

Reinforced concrete frames are necessarily reinforced with a reinforced frame made of corrugated reinforcement or steel mesh. The frame is assembled using resistance spot welding, all metal elements pre-coated anti-corrosion primers. Due to reinforcement it is achieved increased strength and crack resistance of reinforced concrete wells, since the frame takes on all bending and tensile loads, to which concrete has low resistance.

The reinforced concrete tank, which is the main part of the structure, is equipped with ducts for cable entry (their size and number depend on the model of the well). According to the provisions of the technical specifications, the nozzles can be located anywhere, but the distance between them must be more than 5 cm. The nozzles are connected to the protective sleeves of the cable wiring, which are used as plastic pipes, by extrusion welding, rubber cuffs or compression couplings.

Also included with each well is a lid that closes the hatch in the upper part of the structure. Finished cable wells can be coated with hydrophobic compounds, which prevents them from being damaged by exposure to groundwater

1.1 Model range of reinforced concrete wells

Reinforced concrete communication wells are marked KKS, there are 5 varieties in total - from KKS 1 to KKS 5, the numerical nomenclature in this case indicates the size of the structure (1 - the smallest dimensions and weight, 5 - the largest). Moreover, products KKS 1 and 2 have a 4-sided shape, while KKS 3, 5 and 5 have an 8-sided shape.

KKS wells, depending on the loads they are capable of experiencing, are classified into heavy and light. Heavy structures can be installed under travel areas, while installation of light-type KKS is possible only under pedestrian areas.

The presence of the “GEK” nomenclature in the product marking indicates that it is equipped with brackets and brushes; the “G” marking indicates their absence. Constructions of the KKS-2 standard are equipped with brackets made of KKP-60 steel and threaded brushes; KKS-3, 4 and 5 wells are equipped with exclusively shortened brackets made of UKP-65 steel, fixed to the brushes by welding.

Let's look at the typical sizes of different KKS models:

well KKS 1-80 - 135*106*890 cm (length, width, height), weight - 1.25 t;
well KKS 2-80 - 135*106*157 cm, weight 1.8 t;
well KKS 3-80 - 195*116*181 cm, weight 2.6 t;
well KKS 4-80 - 239*130*200 cm, weight 4 tons;
well KKS -5-80 - 300*162*201, weight 5.4 tons.

If the customer purchased “bare” structures, he can purchase accessories for them - consoles (fastening elements for equipment) and brackets, separately. Such fittings are mounted in the viewing windows provided for it; for this you only need welding machine. The brackets are installed on ruffs, which in turn are welded into the mounting sockets.

In addition to cast iron consoles (marked ERSh), there are also metal consoles (KSO - steel optical console) designed for mounting optical couplings of the MOG-U and MOG-S types. Such consoles are mounted on the outer walls of the wells. In this case, the KSO consoles are fixed not on anchors, but directly on the walls of the structure. The distance from the ceilings is at least 10 cm, the distance between the consoles is more than 55 cm.

IN Lately plastic ones have become widespread sewer wells for telecommunication networks. The popularity of such products is explained by a number of their operational advantages - light weight, long service life, complete tightness and resistance to groundwater, ease of installation and relatively low price.

Such products are marked KKT, KOD and KKTM; let’s look at their main varieties:

One of the advantages plastic structures is ease of installation due to their low weight. Installation begins with the development of a pit, the dimensions of which should be 20 cm larger than the dimensions of the well along each contour. Next, a foundation plate is concreted at the bottom of the pit; if the CC is mounted in the transport zone, the foundation is reinforced. Weight plastic products allows you to install them in the pit manually, without the use of lifting equipment. The housing is attached to the foundation plate using anchors or cables.

Telecommunications cables are connected to the well nozzles using compression couplings (must withstand a pressure of 10 atm) or push-in couplings (DIN 4060 standard). Upon completion of installation, backfilling well with a mixture of sand and cement (ratio 5 to 1) with layer-by-layer tamping every 20 cm in height.

Wells telephone KKS 3-10(80) GEK are made from high-strength frost-resistant concrete for the construction of telecommunications, engineering and technical local networks. They are indispensable for protecting cables from possible damage and provide fast access to networks during their inspection, installation, repair and operational maintenance.

Scope of application

There are several modifications of telephone wells. The smallest in size is KKS-1, and the largest is KKS-5. The wells are designed to provide easy access inside for one person to do the job. The cables located in such KKS are under reliable protection from any type of precipitation. In addition to the size range, telephone wells are divided into heavy and light. Heavy ones are located under the roadway, and light ones are located under pedestrian areas. Wells can be installed in a pre-prepared pit. Installation under the roadway at a depth of at least 330 mm is permissible; under pedestrian paths, sidewalks and courtyard areas at a depth of at least 250 mm. The ground must be carefully leveled.

The seams must be treated with cement mortar, since the well must be sealed to prevent moisture from entering network cables. It is better to install KKS in soils that are non-aggressive towards concrete.

Design and configuration of wells

The telephone well consists of two parts - the upper (with half the side walls and the upper ceiling) and the lower (with half the side walls and the bottom). The joining of these parts is carried out on the construction site by welding the embedded parts. Top part consists of a round hole over which is installed reinforced concrete ring for a cast iron hatch and the hatch itself. Telephone wells with abbreviation "GEK" are equipped with brushes and brackets of types KKP-60 or UKP-65 made of strip steel. The brackets are equipped with anchor bolts and nuts. The telephone well should only be covered with a cast iron hatch of the “t” type (heavy).

The technical purpose of wells can be stationary, through-hole, corner and branch. A stationary well is a well that is used to enter cables. The gateway is placed on straight sections of the canal. Corner and branch telephone wells are installed in places where the channel turns and branches.

Specifications

Water resistance W2 allows the well to withstand water pressure equal to 2 atm
Frost resistance F75 provides a minimum of 75 freezing and thawing cycles before the material begins to deteriorate
Tempering strength of 70% guarantees installation and loading and unloading operations without compromising the quality of the product
Concrete of strength class B22.5 (M200) and higher can withstand mechanical loads, so telephone wells can be installed both in pedestrian areas and under highways
Product reinforcement steel frames class A100, A200 and A300 to achieve enhanced product strength
Telephone wells comply with the standards and requirements of TU 14188-83, which contains all the data on the technology, properties of the materials used, labeling, transportation and storage of finished products

Manufacturing process

The production of telephone wells is carried out using a bench or aggregate-flow method. Pre-prepared reinforcing frames are fixed to the platforms. Next, the frames are concreted. Raw concrete is sent for thermal drying to achieve regulatory quality standards. The combination of heavy concrete and steel guarantees high strength and reliability of the finished product. Based on a set of acceptance tests that all finished products undergo, certification documents are issued.

Storage and delivery

Finished products are stored in stacks of two or three rows. Laying products on their sides is not permitted. During transportation, each well must be secured and lined with wooden spacers to avoid damage. Loading and unloading of KKS is carried out only with the help of special equipment.

Delivery is carried out directly from production. Production facilities are located throughout the central region, and before entering our network, they undergo strict quality control by the legal, accounting and quality departments.

- Where is the post office?
For the convenience of users, we have created a system for distributing the load on managers; if 1 person checks mail, this significantly slows down the work or even leads to the fact that read letters are lost. You can leave a request through the form at the top of the site “Leave a request”, it will go to a free manager and they will call you back within 5 minutes.

- You have mobile number?
For the convenience of users, we have created a system for distributing the load on managers; if a mobile phone is specified, then only 1 person can talk on it, and it will be difficult to reach him during the season.

- Why so expensive?
The price of a product consists of several components, the main one being the cost of the material, which determines the quality of the final product. There is also a markup from the factory and a markup from the trading company, we work on the terms of a dealer discount, so we don’t have a markup separate from the factory, we make money from the fact that the factory shares part of its profit with us, and we, in turn, provide the factory with volume to ensure uninterrupted operation .

- Why can’t you order less than 15 thousand? Do you work only in wholesale?
Some items are manufactured in nearby areas and shipping of these items adds significant cost to the product. We calculated that when ordering more than 15 thousand, the benefit from purchasing products from us becomes greater. If you have a small request for products that are manufactured in your area, it will be cheaper to purchase products at nearby factories. Unfortunately we have this moment There is not a single plant in the Moscow region that has passed our quality check.

- Where can I pick it up?
The products are manufactured in different factories, region and city, the manager can tell you, because the factory is different for each product.

- Why is delivery so expensive?
Delivery is calculated based on the distance of the object from the factory warehouse. The delivery cost is divided by the number of items based on the weight of the product; if you order 1 item, the entire delivery cost will fall on it, but if there are 10 items in the order, the delivery price will be equally distributed over these 10 items.

- Do you work with VAT?
Yes, the company Beton Project LLC works for OSNO and is a VAT payer. All prices on the website include VAT.

- Why is only the office listed on the website and not the plant?
We are a dealer of factories and operate at our office address. Because Our list contains a significant number of factories that have passed our inspection; it is not rational to post all the addresses of factories with products, which would complicate the search for the right factory. If you are interested in where this or that product can be exported, you can always check with the Manager or use our delivery.

- Do you have a warehouse in Moscow?
We do not have a warehouse in Moscow or the Moscow region, because... this will have a negative impact on the cost of the product because it will entail additional costs.

- What kind of plant? What is the name of?
The products are manufactured at different factories, you can always come to the factory and see for yourself the quality of our products. Also, if you have any doubts, you can pay for the products directly to the factory.
