Large-scale construction of low-rise, has become sign of our time, has caused a huge demand for foundation structures, differing in speed of construction, low cost and reliability. And at the base of the building to meet these requirements, there are. Today helical pile foundation is probably the most popular variant of this design on most low-rise construction sites, irrespective of the purpose of the future buildings.
This high demand of this type is based on the grounds of their repeatedly demonstrated merits. Apart from the above, among the advantages of the bases of this type include the ability of the device to various problematic soils, areas at great height difference, even in areas of extremely dense construction, and at the bottom of water bodies, whereby, pile-screw bases commonly used in construction of piers and pier on the various waters. About the cheapness of this design has already been mentioned, it costs about a third less than comparable tape base characteristics.
In most cases, such a foundation work done manually or with a minimum of special equipment. What provided the dignity of a screw-pile foundation from the technical point of view? The basis of these designs, as is clear from their very name, are such products as screw piles. Structurally, these piles are metal (standard - steel) pipe having a pointed end and fixed on him a special blade shape. It is through such a device, the pile is not hammered and screwed into the ground with minimal effort and effort.
There are many varieties of modern screw piles, in particular, distinguish products having welded lugs and equipped with alloy tips. However, these design features have small differences in cost and technical characteristics. It is worth highlight the "winter" piles destined for the installation of foundations in the cold seasons in the frozen soil, with special sample teeth on lopostyah. All types of screw piles are subjected to anti-corrosion treatment, which gives them a life cycle measured in many decades in all operating conditions.
