In order to give the foundation an additional margin of safety, as well as protect it from premature cracking and deformation, it is necessary to take care of its strengthening in advance. For this, many developers use screw piles.
It is worth noting that it is not difficult to get screw piles in St. Petersburg, since many construction companies offer their customers not only services for the construction and installation of supporting structures, but also offer in bulk and retail pile structures. It must be said right away that the screw piles are one of the most popular piles in the construction equipment market, which is why this article is dedicated to them. This type of pile is installed by the screwing method. The design is based on a massive pillar, on the sides of which there are blades. The design is made of steel details, which makes it strong and wear -resistant. In most cases, screw piles are screwed into the ground using special hydraulic machines.
It is worth noting that in some cases, before installing a pile, a leader well is made, which allows to securely fix the structure. At the moment, piles of this type are used mainly for low -rise construction, as well as as supports for the installation of masts and power lines. With the help of screw piles, hangars, berths, bridges, panel structures and frame buildings are often built. Another sphere of use of screw piles is the strengthening of slopes and embankments.
The main advantages of using a screw type pile are the ability to use them in almost any area – in marshy soils, in conditions of dense urban development, near engineering systems and communications. Please note that, using such a design, you can not align the site and completely abandon excavation, since such piles are easily regulated in depth. Moreover, steel screw piles can be used at any time of the year, which makes them universal in application.
