Fences are an integral part of the arrangement of country houses. Fences not only serve as a reliable protection from prying eyes and uninvited «guests». They are the finishing touch of the integrity of the architectural ensemble. Beautiful, elegant and reliable fence, being «face» plot, designed to maintain its aesthetic quality. When constructing any fence, special attention is always paid to the selection and installation of such items as supporting columns. A properly made fence poles increase structural strength and complement her design and style.

The choice of materials for arrangement of the pillars
Choosing the material for the supporting pillars need to focus on the fact that they must withstand the load generated by the sections of the fence, mechanical beats and a powerful wind loads. In residential construction during the construction fencing is often used in metal, wood, concrete or brick pillars.
Metal poles universal in application, as suitable for construction of fences made of metal grid or mesh, wooden fence, plastic sections and corrugated sheet.
Metal structures are made of hollow tubes to provide strength, resistance and durability
A quality tree is expensive. But unfortunately, even high-quality trees are not very durable in the open countryside. In comparison with metal poles, the lifetime of which is about half a century, a wooden structure, even when proper treatment is able to last for more than two or three decades. So often they are used in the arrangement of low hedges, front gardens and temporary fences.
Wooden pillars is one of the simplest variants of the arrangement of the fences, but not the cheapest. Fences made of wood is always aesthetically pleasing and prestigious
Concrete and brick pillars it is advisable to install only if the device is heavy fences. However, sometimes the brick pillars people set up as decoration. In this case, they are excellent «hallmark» for a rich plot.
Concrete posts are relatively inexpensive and technologically. They, like metal support pillars provide strength and durability
Brick pillars – one of the most expensive options for decorating the fence. Due to the variety of modern materials fences made of bricks are a worthy decoration of the facade
Marking fence design
Deciding to build a fence, you must identify its location on the site and to calculate future posts. The correct calculation will help to prevent buckling and collapsing of the enclosing structure in the process of operation.
The average distance between the pillars does not exceed 2.5-3 m
The required number of poles is calculated depending on the length of the entire building envelope and size of the sections of the fence.
Technological options for the installation of pillars
The method of installation of the poles for the fence is determined by the design feature of a fence and the nature of the soil.
The universal way — concreting
Installation of fence poles universal method is well suited for mounting metal, concrete and wooden structures on stable neveroyatnyh soils. This method involves digging the hole under the prop, installing the post and filling the remaining space with concrete.
Application of borax will significantly ease the process of digging a hole and digging
To improve the efficiency of drilling by using water, which is poured into the hole and wait for 10-15 minutes so that the ground became softer and more pliable.
To install the poles with a height of four feet is sufficient to dig a hole with a depth of 0.5 m, and for mounting higher supporting pillars — 0.8 m on average, post bury 1/3 of its length.
Deciding to dig the support poles for the fence to have the soil, can not do without the use of concrete
Council. It is sufficient to use a drill, the diameter of the blades which fully corresponds to the diameter of the pole. This will avoid «the loosening of the» borehole region: poles into the ground tightly and do not require additional concreting. However, this method requires skill strictly vertical drilling holes.
But how to set the poles for the fence on «complex» soils with high levels of groundwater? Indeed, in such conditions it is necessary to bury the substructure below the level of soil freezing, and it is in the traditional concreting of the Foundation is a troublesome and expensive undertaking. In such cases, before installation of towers the bottom of the pit is lined with a layer of gravel with a height of 15-20 cm.
The pillars are immersed into the hole and align vertically the building level or plumb. After that, the empty space around the entire circumference of the pillars is filled with a layer of gravel
This crushed stone «pillow» at the same time acts as a drainage support structure and softens the impact forces of frost heave. The layer of gravel should not reach ground level 12-15 cm: the remaining space of the hole is concreted with fresh solution.
The clogging of the supporting pillars of metal structures
Driving posts is one of the easiest and cheapest ways of installation of support metal structures.
This method is effective when constructing fences on malokamennaya soils, composed of dense layers of rocks
Score a small five-foot poles for the fence using a hammer. For mounting the three-meter poles can be used «grandmother» device for the money this piles, pipes or poles into the ground
Design is a metre piece of a pipe, one end of which is tightly sealed and weighted 15-20 kg. At zakolachivanii «grandmother» the guide structure is in the pipe, which allows to increase the accuracy of the strike, because it must be run strictly along the axis of the object.
When driving posts with «grandmother», difficulties may arise when construction hoist. To facilitate the work, privaris to her long handle, which as plugging in adjusting to the most comfortable position.
Construction of concrete base for brick fence
Traditionally, these pillars are built on concrete strip Foundation or columnar. Strip Foundation is a continuous reinforced concrete strip to a depth of 500-800 mm, a width 100 mm greater than the width of the fence.
Since the columns of bricks are quite heavy construction to put the brick pillars for fence, you need to make low-depth basis
For the erection of such bases need to dig a trench. In the bottom of the trench are driven pipe, which subsequently will act as a Foundation for brick pillars.
The trench is filled with 300 mm layer of sand, gravel, broken bricks and tightly tamped
The perimeter trench is established formwork, equipped in such a way to prevent the loss of moisture from concrete and mortar to provide waterproofing design.
The Assembly of the formwork is illustrated in the video:
After the arrangement of formwork start tying the reinforcement cage and filling the trench with a concrete solution. The concrete hardens within 5 days, but the fence you can start to build after a couple of days after the laying of the Foundation.
The mounting posts screw piles
The use of piles can significantly reduce the cost of the construction process. The cost of screw bases are much lower in comparison with conventional bar or strip.
In the last decade with the construction of fence posts as a reliable basis quite often use screw piles
Piles are easily installed by hand or with attraction of means of small mechanization. They like «the screws» screwed into the ground, compacting as penetration mezhlopastnogo space, and form a reliable basis for heavy building structures.
Technology of installation of screw piles:
