Attach the board to the asbestos pipe. Asbestos-cement pipes - to a private developer about asbestos-cement pipes. Advantages and disadvantages

One of the most popular and in demand in modern country houses holders for the fence are asbestos pipes. This material has proven itself not only for sewerage installations, but also drainage system, chimney or hood, but also for the most ordinary fencing. Wood rots and deforms when exposed to moisture, metal is susceptible to corrosion.

Also, both materials require regular cleaning and painting, while asbestos cement is a more convenient and easy-to-maintain material. The production of asbestos cement is carried out by mixing Portland cement mortar and asbestos fiber. The pipeline is different increased strength and smoothness over the entire surface, however, just like other materials, it has both advantages and disadvantages.

Advantages of asbestos pipes

The choice of materials for building a fence today is extremely large. Asbestos pipes are used as fence holders due to a number of advantages:

• Moisture resistance;
• Resistance to pests;
• Long service life;
• No need for processing;
• Affordable price;
• Various diameters of products, which allows you to choose best option holder for any fence.

Disadvantages of asbestos-cement holders

Despite its apparent advantages, asbestos fiber is not an ideal material and requires particularly careful handling.

The disadvantages include:

• Fragility of the material;
• The need for increased caution during transportation and installation;
• Large weight and bulk;
• If moisture gets inside the pipe in winter, it may crack;
• Lack of attractiveness of the fence.

In fact, many disadvantages can be leveled out if you approach the installation process correctly. For example, to prevent moisture from getting inside the pipe, you can cover the top hole with any moisture-resistant material that has suitable sizes.

If you have weighed all the pros and cons of an asbestos pipe and still decided on this material for building a fence on your summer cottage, you need to familiarize yourself with the key points installations. The range of asbestos-cement products is quite large, but it is better to give preference to pipes that have a slightly larger diameter on one side due to reinforcement. If you cannot find such material, you will have to strengthen the holders yourself by placing scraps inside metal pipe.

Most often, asbestos pipes with a diameter of 100 mm are used for the fence, although in rare cases it is possible to install a structure using products with an even larger diameter. The height of the fence is a purely individual matter, usually it is within 200 - 300 cm.

What else can you make an inexpensive fence from? Read here - all about fences.

Step-by-step installation

Installation requires the following steps:

1. 1. Construction of the foundation. It is necessary to determine in advance how many centimeters will separate one pillar from another.

The distance between asbestos fence posts depends on what material will be used for cladding. It is most optimal to place the holders 200 - 300 cm from each other.

1. 1. Holes must be drilled in the ground. The diameter of the holes for laying concrete holders must be at least twice the diameter of the pipe. How many centimeters deep the hole should have depends on the density of the soil, the length of the spans (200 or 300) and climatic conditions on the ground.

The optimal pit depth for installing holders is 200 - 300 mm.

1. 1. The bottom of each hole must be concreted with mortar or insulated with roofing felt.

Waterproofing each hole is a prerequisite, which ensures a long service life of the entire structure.

1. 1. Then you should pour a sand and gravel cushion.

1. The sand must be compacted tightly and a holder must be installed on it.
2. It is recommended to fill the underground part of the holder with concrete to increase stability. The concrete layer should not exceed 200-300 mm.
3. Leave for several days for cementation.
4. Then you can begin installing the load-bearing beams with cladding.
5. To attach the load-bearing beams in the pillars, you will need to drill holes.
6. To connect metallic profile with a supporting beam, you can use wire or special clamps.
7. To connect to a pipe wooden beam, ordinary screws are enough.

It is also possible to install without using cement mortar. This effective method installation on heaving soils that are capable of pushing out the concrete pad along with the entire structure. For cementless installation:

1. Drill holes several times larger than the diameter of the pillars, i.e. 200 or even 300 mm.
2. Install the holder and that's it free space fill with crushed stone and compact.

In this way, natural drainage is produced, which allows pressure to be removed from the fence structure. There is also a way to install asbestos pillars by drilling holes in the ground using a special drill.

Asbestos-cement pipes are widely used in the construction of a wide variety of residential and industrial facilities.

Currently the following types of pipes are produced:

Gravity - pipes with diameters of 100, 150, 200 mm, length 4 and 5 m, in accordance with GOST 1839-80. Pressure - pipes with operating pressure characteristics of 6.0 or 9.0 atmospheres, diameters 100, 150, 200, 300 , 400, 500 mm, 5 m long, in accordance with GOST 539-80.

Asbestos-cement gravity pipes They are mainly used for the installation of external free-flow sewerage, the manufacture of tubes for chimneys, boilers and stoves, as well as for the protection of electrical or telephone communications. Quite often, such pipes are used when installing fences as fencing posts.

Asbestos-cement pressure pipes are used in the organization of sewer, drainage, water supply and other technical networks under pressure. Often such pipes are used for watering or irrigation. Architects and designers love to use them as columns in interior design.

TO undoubted advantages Asbestos-cement pipes include their following qualities:

resistance to corrosion and aggressive environments; non-flammability (resistance to fire); durability and non-toxicity; more affordable price, compared to the cost of other similar products; ease of installation; use without a waterproofing layer.

An asbestos-cement coupling with rubber gaskets is used to connect pressure pipes. Free-flow asbestos-cement pipes are connected using a polyethylene coupling.

Despite the popularity of modern fencing, fences made from asbestos-cement pipes still hold a strong position in the market. And in combination with new manufacturing technologies, its quality in many respects exceeds that of only wooden fencing, but even the same metal ones.

Wood is susceptible to rotting and rotting, metal rusts. And an asbestos-cement pipe, coated with a special glaze, can stand for decades, and, at the same time, without requiring treatment or painting! It was these two qualities - low cost and resistance to dampness and pests - that made it so popular among the poor.

To this day, families with fairly large incomes prefer to take metal holders. In support of them, it is necessary to mention the high fragility of asbestos-cement pipes, which creates certain difficulties during transportation and installation. Like an asbestos-cement pipe, it is heavy and bulky, which makes its installation even more difficult.

There is nothing you can do to add to this that you should not allow water to get inside, which in winter, expanding and freezing, can split the pipe. And, of course, an important indicator of any fence is its sophistication, which cannot be said about a fence with asbestos-cement holders. But still, since you decide to install asbestos-cement pillars, then the most suitable cladding will be a beam, chain-link mesh and corrugated sheeting.

Construction of a fence with asbestos-cement pillars

The process of building a fence begins with the installation of asbestos-cement pillars-holders. The distance between them is determined depending on what material will be used to avoid lining the fence. To install the pillars, holes are drilled in the ground, the diameter of which must be at least twice the diameter of the pipe. The bottom of the pit needs to be extinguished cement mortar or pave the bottom waterproofing material(for example, roofing felt). This is done in order to prevent contact between the soil and the sand and gravel cushion.

The latter must be poured before installing the pillar. The depth of the pit, as a rule, is proportional to the ground part of the pillar, although of course it is determined in accordance with the density of the soil, the length of the spans, the diameter of the pipes, the windage of the cladding and the front situation in the region. Read also How to heat a greenhouse and hotbed: all possible options For pillars, it is advisable to choose pipes with a thickening at one end, some are buried in the ground. If it was not possible to find such pillars, then the end that will be buried needs to be strengthened by inserting thick rods, sheet metal, pieces of metal pipe, etc.

Therefore, the pipe with the reinforced end is installed in the pit directly on a layer of sand and gravel cushion, some of which must first be well compacted. Then iron fascias are hammered into the bottom of the pit, which will increase the strength of the poured concrete. The cavity of the underground part of the pillar also does not prevent it from being filled with concrete to give greater strength. In this way, holders are installed around the entire perimeter of the future fence. After a few days, you can begin fastening the load-bearing housing with subsequent cladding. To attach the load-bearing part, holes are drilled in the pillars.

If a metal profile is used as a house, then the cladding can be fastened using wire or clamps. If the beam is wooden, then you can use screws. If you need a fence of maximum strength and a long service life, it is installed from reinforced concrete structures, brick or stone. But if there is no need for special stability and durability of the fence, you can install a fence made of asbestos-cement pipes, between which fence sections made of wood, profiled sheets are fixed, or hang a metal mesh. Asbestos pipes ensure long-term operation with proper installation. Unlike wooden and metal poles , asbestos-cement pipes are practically not subject to rotting and corrosion. This type of pillar is used for stretching chain-link mesh and connecting wooden spans.

Correct installation and connection using a coupling, the calculated depth of the holes and high-quality pouring of concrete will ensure long-term operation of the fence. To connect asbestos pipes together, polyethylene and asbestos-cement are used couplings. On inside couplings have a rubber ring. When the coupling is connected to a pipe, it remains installation gap, which allows the pipe to deflect at an acceptable angle. Couplings are reliable clamps of pipe connections.

Couplings can be used to fasten the pipe scraps remaining after installing the fence. By connecting the scraps using a coupling, they can be used as posts. The disadvantages of fences made from asbestos-cement pipes include: Fragility. If dropped or hit, they easily split. Susceptibility to defrosting. In asbestos-cement pillars that are not filled with concrete, water that gets into the pipe cavity winter period freezes. As a result, the pipe bursts at the level of filling with water. Unaesthetic appearance. Installation of asbestos-cement fence posts To install a fence, standard asbestos-cement pipes with a thickness of 9 mm, a length of 3950 mm and a diameter of 118 mm are suitable.

Before installation, the posts are cut with a grinder to the height of the fence. Asbestos pipes can also be cut with an ordinary hacksaw. An ordinary fishing drill (auger) is suitable for drilling holes. It can drill about 40 holes in a day. The depth of the wells depends on the installation conditions of the fence: soil type, wind load and span length.

On average, it is 800 mm. This will be enough for the stability of the pillar. The part of the asbestos pipe located in the ground is practically not subject to corrosion and rotting. Then we insert the pillars and fix them in vertical position. Sometimes, before installing asbestos-cement pipes, metal rods are driven into the ground. By pouring the solution inside the column, you can get a reinforced structure. Having installed the corner risers, we stretch a cord between them along the upper ends. We install intermediate pillars along the cord. If the hole is not filled with concrete, it is first waterproofed.

This prevents the sand from combining with the clay. Heaving soil tends to push the pillars out of the hole when it freezes. When the hole is filled with concrete, the pushing effect of the soil increases. Therefore, the concrete layer should not exceed 30 cm, and the rest of the volume is filled with sand. During installation on a gravel-sand cushion, the soil at the base of the pipe is periodically watered and compacted.

to install best connection with soil, it is more practical to use pillars with an extension at the bottom. For greater stability of fences under heavy fence spans, you can pour a concrete base under the pillars and strip foundation for sections. A single foundation will ensure durability and reliable connection of the fence. To attach horizontal crossbars, we drill holes for threaded rods. A metal profile pipe or wooden beam can be used as crossbars. The wooden beam must be coated with an antiseptic compound. When using a metal profile, we coat it with a metal primer. Having installed the fence posts in this way, we attach them to flat slate, corrugated sheets, wooden boards or chain-link mesh. Wooden spans fastened with clamps using self-tapping screws. The chain-link mesh is secured with wire. Fastening pillars without pouring concrete During the usual installation of asbestos-cement pillars, concrete is poured into the free space between the edges of the hole and the pipe.

And it is considered a sustainable design. But the poured concrete rests on the same unstable soil and nothing holds it. In this regard standard way applicable only on light, non-heaving soils. Heaving soil will just as easily push out a pillar with poured concrete. The force of heaving even destroys the foundations of large houses.

Burying the pipe below the freezing level of the soil solves the problem, but it also consumes a large number of concrete and the pipe is buried almost half its length. There is universal method installation of asbestos-cement risers on any soil without concrete. A hole is drilled with a diameter larger than the diameter of the pipe. After installing the asbestos pillar, the space surrounding it is filled with fine crushed stone and compacted. This creates effective moisture removal around the post and turns heaving soil into stable soil. When using concrete, it prevents groundwater and when it freezes in winter, it is pushed to the surface. With the described method, water freely goes to a depth below the freezing layer, where natural drainage occurs. There is no pressure on the asbestos-cement column. If the fence is installed on sandy, non-heaving soil, holes are drilled immediately to the diameter of the pipe.

Buying a special drill is cheaper than the cement spent when installing a fence traditional way. But this work requires certain skills when drilling holes with strict verticality and strictly along the fence line.

It protects and separates the site from the street, neighboring sites, and serves as a border for economic zones.

The fencing of a dacha consists of sheathing, load-bearing elements, and entrance openings. There can be several entrance openings (gates), it all depends on the need for this design and the taste of the owner. Here their passage capacity must be taken into account, which is at least 2.7 m for passage passenger car, 3.5 m - for the passage of freight transport. Load-bearing elements are pillars to which beams, veins, frames, and wires should be attached. The sheathing is made of slats, round picket fence, brick, metal, concrete, wood, chain-link mesh, etc.

d. Average height fencing - 1.5 m. Asbestos-cement poles are very reliable in the construction of fences. Today, the use of asbestos-cement pipes for dacha fences is popular. They are high-tech, superior to wooden and metal constructions, vulnerable to aggressive influence. The process of erecting such a fence for a summer residence takes place in several stages.

Calculation of fence spans along the perimeter of the site, cutting pipes, drilling wells

Foundation options for a fence using asbestos-cement pipes.

Unpretentious and affordable poles can last for decades. Proper installation of asbestos-cement pipes, calculation of burial depth and knowledge of technology ensure their long-term operation.

Asbestos-cement fencing posts are best combined with structures made from chain-link mesh, wood, and corrugated sheets. In order to install poles, you need to be well prepared for the installation process. Most often, pipes with the following technical characteristics are used:

external diameter - 118 mm; internal diameter - 100 mm; wall thickness - 9 mm; length - 3950 mm; weight - 24.1 kg.

For cutting pipes required size use a grinder with a diamond wheel. Distance between load-bearing elements the fence depends on what material will be used as the sheathing. On average it is 2-3 m.

After calculating the spans for the pipes, wells are drilled with a hand drill; their diameter should be twice the outer diameter of the pipe. Typically the depth is 70-90 cm. It is usually proportional to the ground part of the support and, of course, is determined depending on the composition of the soil, the length of the spans, the windage of the sheathing (susceptibility kinetic energy air flow) and wind conditions of the climatic zone.

Fastening the fence to asbestos-cement pipes using studs and clamps

Hairpins(for fastening metal canopies), cut to size from ready-made studs 1 m and 2 m. d= 8mm (since, ready-made studs, required length, Have not found).

Clamps made from a metal strip 2-3 mm with drilled holes under self-tapping screws. I tapped the strip along the diameter of a piece of pipe.

Asbestos cement pillars installed on a sand and gravel bed, filled with concrete on top ( thin layer). Inside the pillar, metal pins are driven into the ground and filled with concrete (almost under the top of the pillar), to give strength and prevent moisture from getting inside the pillar (otherwise, the pillar can be cut off like a razor in the place where the water level is).

Asbestos cement pillars d120 mm (internal d100) for the fence I used a length of 1.8 m (1.2 m above ground level) (preferably a longer length), but these were in stock, i.e. They had been lying there for about 20 years and were waiting in the wings (moreover, several columns lay completely buried in the ground and nothing happened to them).

The distance between the pillars is 3m (convenient, because the length of the bars is 50x50 = 6m)

And for the gate, I took asbestos cement pillars 3m (above ground level 2.30). I additionally concreted them into glasses from sections asbestos cement pipe d200-250 mm. Inside the pillars (for gates), Necessarily, you need to pour concrete (not very thick, so that it flows through the fastening studs). And for a fence, you don’t have to pour concrete inside the pillars(just be sure to close the top hole).

Despite the popularity of modern fencing, fences made from asbestos-cement pipes still hold a strong position in the market. And in combination with new manufacturing technologies, its quality is in many respects superior not only to wooden fences, but even to metal ones.

The fencing construction process begins with the installation of asbestos-cement support posts. The distance between them is determined depending on what material will be used for cladding the fence. To install the pillars, holes are drilled in the ground, the diameter of which must be at least twice the diameter of the pipe. The bottom of the pit must be filled with cement mortar or the bottom must be lined with waterproofing material (for example, roofing felt).

A fence made from asbestos-cement pipes is more reliable and durable than a wooden or metal one, which is vulnerable to aggressive environmental influences. Durable, inexpensive and unpretentious, racks can last for decades without requiring periodic painting. Correct installation, calculation of the required depth and knowledge of pouring technology ensure their long-term operation. Asbestos-cement fence posts are best suited for structures made of corrugated sheets, wood and chain-link mesh.

Advantages and disadvantages

The most important factor What determines the popularity of asbestos-cement pipes is their affordable cost and the absence of corrosion and putrefactive processes. Asbestos-cement fence posts have significant drawback: They are inconvenient to work with. When water gets inside and freezes, the asbestos pipe bursts exactly along the liquid boundary. In addition, it is characterized by increased fragility, and when hit or dropped, it splits. Unaesthetic appearance also limits the popularity of asbestos products. All these features should be taken into account when installing poles.
