The fence on screw piles: fencing for unstable soil

When planning the construction of a fence on a plot, each owner wants to get reliable, durable and aesthetically designed fencing that will protect his possessions from prying eyes and «uninvited» guests. The fence on screw piles is the optimal solution of the arrangement of solid fences, the construction of which does not require large financial investments. Screw piles received over the last decade widespread in residential construction, allow to build a reliable support even in the conditions of floating «unstable» soil.

What is the advantage of pile construction?

Wide application in construction, they find thanks to a number of advantages:

  • The possibility of installation in «complex soil». The fence on screw piles can be built not only on the peat and loam, but any soil with high levels of groundwater. The installation of the piles can be even in a swampy area, on a diverse terrain and slopes with a great elevation.
  • Construction in any season. Screw piles are easily installed in all weather conditions. No wonder they are frequently used in the construction even under conditions of permafrost.
  • Ease of erection. Screw piles under the fence is a metal pipe with welded or cast lugs, which are like screws, just screwed into the ground. Screw «screws» in the ground is possible by hand without the involvement of construction equipment.
  • The speed of installation. For screwing up one of the piles takes no more than 20-30 minutes. Build a reliable pillars on screw base in just a couple of days.
  • A long service life. Screw piles are able properly to last for about 50 years. If before you install them in addition to process anti-corrosion composition, these products will last over a hundred years.

Screw piles for the fences is one of the most economical options for arrangement of reliable support. In comparison with the same tape or pier Foundation, the cost of screw base comes out 40-50% cheaper.

In addition, the pile can be reused. This gives you the opportunity at any time remove the mount and install on any other place of the site.

Screw piles – reliable support

Screw piles are a versatile type of Foundation that you can lay under fence on private personal territories, and under heavy multi-storey buildings for housing and industrial objects

Select the appropriate option piles

Bearing capacity of piles depends on the diameter of the pipe. For the erection of a fence on stilts with their hands enough to use the pipe diameter 54-108 mm, which have a wall thickness of 2-8 mm. pipe with a diameter of 54 mm suitable for erection of wooden fence, and light fences of plastic or metal mesh.

Piles d=89 mm capable of withstanding a load of metal fences or fences of corrugated Board. Load characteristics of pile d=108 mm is quite high: they can withstand not only lightweight fences, and greenhouses, terraces, gazebos, and other landscape design elements.

For a more accurate determination of the length of the article you want to preview the screwing. The immersion depth of the soil pipe depends on the composition of the soil: it can be sunk as 1 meter and 5 meters. On average, the piles are screwed to a depth of 1.5 meters.

Design feature of screw piles

To apply screw piles are convenient because they do not disrupt the landscape pattern of the area, as are soil layers «point»

The most important thing that is worth mentioning in this paragraph is that the market can meet special piles for fences, which already has holes for mounting spans of the fence.

Basic rules for installing «screw» fence

Before construction of the fence on stilts should conduct a trial screwing, through which you can define the limit of the deepening of design and the quality of the soil. Rules of laying of the Foundation below the level of soil freezing should be strictly adhere to, erecting a fence in wetland soils soils.

It is necessary to result in seasonal fluctuations of soil and under the action of forces of frost heaving, the support in the process of operation is not pushed out to the surface and was securely fixed in the soil layers.

Screw piles, and other support structures for a fence, installed at a distance of 2.5-3 meters. Having defined the place of erection of the fence and calculate the required number of supporting pillars, you can begin the breakdown of the indicative pegs, in place of which in the future will be built pile.

Piles can be screwed in as in the manual way, and using small tools. The preferred screw piles are not alone, and with two assistants.

The pile is equipped with a homemade lever

Greatly facilitate the installation process will help the use of lever to make which can be made of metal rod

To create a lever at the upper end of the pile, in which there are technological holes, inserted the usual fittings d=3 cm On both sides of the rebar are placed pieces of square pipe, which subsequently will act as a lever. The optimal length «sleeveless» the lever is about three meters.

To simplify the construction of the screw base by hand using a special two-handed collar with a clip that looks like a pipe wrench. With this tool it will be convenient to control the vertical position of the screwing pipe.

The correct depth of the screw rod

Piles need to screw into the ground at a right angle, strictly maintaining their vertical position and location in terms of

Special equipment

If you want to save time and you do not mind the material means for this — feel free to hire professionals. Special equipment will help with large volumes and limited time frame

For screwing piles there are also special machines by which you can control the vertical position of the structure relative to its axis. Vertical immersion is necessary in order to measure penetration «screw», mezhlopastnogo space is condensed, and construction gained strength and stability.

Supporting columns on screw piles

After the installation of the piles is necessary to trim to the desired level. To control the height and horizontal position of the aerial parts of piles easily with a level or hydraulic level

If you do a heavy fence, then the point of the pile from the ground is better sealed with a special solution of M-150. The seal will protect the internal part of the structure from moisture and to improve its bearing capacity. As surface treatment elevated outer part of the pile two-component primer and anticorrosive composition will extend the life of the product in any case, whatever fence you do.

Sometimes the variant «spun pile and put it in the post», like here:

This option also has the right to life, it is very well proven.

After all the piles are screwed, operacine, on which are mounted the elements of the fencing installed to the posts using screws or dowels on metal. When building a fence netting, attach the mesh using a soft wire or metal clamps. So the grid does not SAG through one of the upper rows of cells must be routed tightly stretched wire or rod.

That’s all. The fence on screw piles will serve as a reliable protection of the site, in no way inferior in strength to other types of fencing.
