The fence on screw piles: fencing device for unstable ground

The fence on screw piles: fencing device for unstable ground

When planning the construction of a fence on the site, eachthe owner wants to get a reliable, durable and aesthetically decorated with the fence that will protect his possessions from prying eyes and "uninvited" guests. The fence on screw piles - the optimal solution arrangement lasting fencing, construction of which does not require large financial investments. Screw piles have received over the past decade, widespread in a country construction permit to build a reliable support even in plyvuchih "unstable" soils.


What are the benefits pile construction?

Widely used in construction, they are due to a number of advantages:

  • Can be installed in "difficult conditionssoil. " The fence on screw piles can be built not only on peat and loam, but also on any soil with a high level of underground water. Assemble piles can be even in a swampy area on diverse topography and slopes with a large height difference.
  • Construction in any season. Screw piles are easy to install in all weather conditions. No wonder they are actively used in the construction even in the permafrost.
  • The simplicity of the construction. Screw piles under the fence are metal tubes with welded or cast lugs, which, like screws, simply screwed into the ground. Screw the "screws" in the ground, you can manually without involving construction equipment.
  • Speed ​​of installation. Screwing on one pile takes no more than 20-30 minutes. Raise reliable pillars on the basis of the screw can be just a couple of days.
  • Long service life. Screw piles are able to properly serve about 50 years. If, however, before installing them further processed composition of corrosion, these products serve more than one hundred years.

Screw piles for fences - one of the mosteconomical option arrangement reliable support. In comparison with the same tape or pier foundation, the cost base of the screw comes to 40-50% cheaper.

In addition, the piles can be reused. This makes it possible at any time to disassemble and install the support at any other location area.

Screw piles - a reliable support

Screw piles - a universal view of the base, which can lay under a fence on private gardens areas and under heavy multi-storey buildings for housing and industrial facilities

We select the appropriate option piles

The bearing capacity of piles depends onpipe diameter. For the construction of the fence on stilts with their hands enough to use pipes with a diameter 54-108 mm, which have a wall thickness of 2-8 mm. Pipes 54 mm diameter intended for the erection of a wooden picket fence and the light from a plastic or metal mesh.

Piles of d = 89 mm can withstand a load,created by metal fences or fences made of corrugated board. Load characteristics piles d = 108 mm high enough: they can withstand not only lightweight fences and greenhouses, terraces, pergolas and other elements of landscape design.

To more accurately determine the length of the productyou must perform a pre-screwing. soil pipe immersion depth depends on the composition of the soil: it can be recessed as 1 meter, or 5 meters. The pile is screwed onto the middle of 1.5 meters deep.

Design features a screw pile

Apply screw piles convenient because they do not violate the landscape drawing area, as are soil layers "dot"

The most important thing that is worth mentioning at this point is that the market can meet the special piles for fences, which are already provided mounting holes span fences.

The basic rules for installing "screw" the fence

Before the erection of the fence should be on stiltsconduct trial screwed, through which you can define a limit to deepen the design and quality of the soil. Rules laying foundation below the soil freezing strictly be followed, erecting a fence on the soil saturated with water.

It is necessary that as a result of seasonalground motion, and under the influence of the forces of frost heaving, support during the operation is not pushed to the surface, and reliably has been fixed in the soil layers.

Screw piles, as well as other support structuresintake, set at a distance of 2.5-3 meters. Having defined the place of erection of the fence, and calculating the required number of supporting pillars, you can start the indicative breakdown of the pegs on the site which will be built in the future of the pile.

Piles can be screwed as a manual way, and taking advantage of small-scale mechanization. The most convenient way to screw piles are not alone, but with two helpers.

Pile equipped homemade lever

Significantly ease the installation process will use a lever, which can be done from a metal rod

To create a lever the upper end of the pile, inwherein there are technological holes, inserted conventional valves d = 3 cm. On both sides of the pieces are put armature square tube, which will later serve as a lever. The optimal length of the "arms" of the lever is about three meters.

Simplify the work on the construction of the screwthe base can be manually, using a special two-handed collar with a clip that looks like a pipe wrench. With this tool, it will be convenient also to control the vertical screwing the pipe.

Correct penetration of the screw rod

Piles must be screwed into the ground at right angles, strictly maintaining their vertical position and location in terms

Special equipment

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

For screwing piles, there are alsospecial machines, by which to control the vertical axis with respect to its design. Vertical Descent is necessary in order to the extent of penetration "screw" mezhlopastnoe space thickens and construction design regained strength and stability.

The supporting pillars on screw piles

After installing the piles necessary to carry out cutting to the desired level. To control the height and horizontal position of the aerial part easier piles using leveling or hydraulic level

If you're doing heavy fence, the exit sitepiles of earth better seal special M-150 solution. The seal will protect the interior of the structure from moisture penetration and increase its load-bearing capacity. A surface treatment of above-ground parts of the outside of the pile of two-component primer and anticorrosive will extend the life of the product in any case, whatever you did not do the fence.

Sometimes the variant "twisted pile - inserted in her post", like this:

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

Once all piles screwed, operechiny onwhich are fixed elements of fencing, installed to the posts with self-tapping screws or dowels for metal. When constructing fences, netting, mesh can be attached to a conventional soft wire or metal clamps. To the grid did not sag, through one of the upper rows of cells need to stretch taut wire or rod.

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