Features installation of screw piles with their hands , a full description of the technology

In most cases, the individual building settling foundation of the belt type, and most of all - a monolith.One of its virtues is called the simplicity of construction and the ability to perform all the work, without resorting to the services of specialists, without the use of specialized equipment.But on a structure such as a house on screw piles, for some reason it mentioned much less frequently.

However, it is no more expensive building (and sometimes it costs much cheaper), and on a number of parameters of the existing and construction of advantages over traditional types of foundations.Here is how to install the piles, we'll talk without touching of the work on the construction and decoration of buildings grounds.That will be quite enough to understand the main advantages of these products.

assumed that test drilling has produced and soil characteristics are known.

Selection

samples During the construction of private homes, experts advise to focus on the 108 mm piles.Their length is determined by the depth of soil freezing and grillage height (base) of the building.As a rule, the majority of Russian regions are used in the product 2.5 m.

Tracing section

This work is greatly simplified, as opposed to training areas for other types of foundations.Suffice it to clean the area of ​​debris and vegetation.Partitioning is the placing of pile installation, and it is done so as to prevent sagging of the lower rim elements (the reference beam).The maximum distance between piles - 3 m.

The first "signal" pegs (reinforcement bars) are placed at the corners of the base circuit.It should be borne in mind that the structure of the complex architecture of the pile are placed at every turn, as well as in places of joints of walls (external and internal).If you provide any outbuildings (garage, a terrace, and the like), then under the part of the building as laid piles.

often in articles on pile foundations, indicates that the structure is parallel to the adjacent structures, roads.On the basis of what is given such a recommendation?How to plan the location of future home - on the edge of the area, deep, straight or diagonally - all at the discretion of the owner.What is the best (in terms of utility services, the overall landscape, and so on), and is done without "looking back" to anyone's advice.

Installing piles

The target site is dug a small hole, sufficient to bury the product of 30 - 40 cm. Each pile is at the opposite end of the working part of a specially prepared diametrically opposite holes (called technology).They serve to ensure that they could thread the lever for imparting torque article.

necessary to constantly monitor the verticality of the future home support.Some artists do so - at the upper end of the pile is fixed cord with hanging sinker (plumb).After 1 - 2 full turns are convinced of the correctness of "penetration".At the same time, and rest, and adjust the direction of the "drill".
recommended to twist the product at least half a meter, as in most parts of the country deeper into the ground does not freeze.Navigate to the need to force required to screwing piles.It is desirable that it stops at the solid layer.

Trimming top of

done taking into account the expected rise of the house.Since one of the advantages of pile foundation is the possibility of its construction on uneven terrain, you need to focus on the most protruding above the surface.But in any case, should be cut below the tooling holes.If they leave, then load this part of the piles will be deformed.

Concreting

Often you can find the information that it protects the pile from corrosion.This is not entirely correct, since any concrete is able to absorb moisture.Therefore, if we talk specifically about the protection, it is - only partially.The main task of concreting - to increase the strength of such support, protect the hollow, in fact, the product of the deformation at the ground displacements.Some of the walls will not stand, and therefore they need to be strengthened.

Installation pile tip

This is done by means welding machine, but its design (top part of the support) may be different.How to do this depends on the destination and weight of the building.In addition, there is supposed to be mounted grillage or not?

After welding the treated area must be covered with anti-corrosion agent.

What to look

• Do sheeting piles?If the products are cheaper, which is due to reduced price?If the surface treatment is not carried out by the manufacturer, then it should be done independently.On sale is the appropriate means.
• To correctly determine the overall elevation of the house, the first screw pile on the highest point of the site.According to her, "equalize" all others who put in the corners and on the perimeter of the bends.After their installation angles between the tensioned cord, which serves as a guide when fitting the intermediate piles.
