For the past few years, you can meet more and more houses made using pile technology. Pile-screw foundations are actively used in the construction of low-rise country houses, a variety of architectural forms, when installing power lines, parking, pipelines, pier and berths.
The most interesting thing is that you can use screw foundations on different types of foundation, even the most difficult. Regardless of which soil, even swampy or peat, pile foundation can be installed everywhere. The only exception in this situation is the rocky surface. Rifle piles have a Rad of significant advantages, however, so that all of them manifest themselves fully, it is necessary that they are correctly established. Otherwise, if the installers make mistakes, this can lead to serious problems, up to the destruction of the most erected building.
One of the main mistakes that are found in the construction of screw foundations is to remove the already installed piles. What happens when screwing? The earth is compacted, allowing piles to stand more stable, thereby making a more reliable house. If you unscrew them, then the soil will loosen and subsequently sink, which can lead to the destruction of the walls of the building.
The device of screw piles requires a certain correct screwing angle from the installer. Inappropriate installation is not permissible. If pile collides in its path with an insurmountable obstacle, it can go aside. In this case, the deviation angle cannot be more than 2 degrees. Otherwise, this is fraught with the most negative consequences. Due to the instability of the pile, the entire foundation will be unstable. If the angle was still changed, then it is necessary to change the size of the screw pile. This will help to achieve the desired verticality. And one more important point: a pile, which is screwed at an irregular angle, cannot be increased.
SNiP screw piles, the thickness of which is 4 mm or less, should be concreted. This will increase rigidity and resistance to bends, thereby preventing, thereby, a possible rupture of the pipe, when exposed to low temperatures on it. When concreting, it is important to remember that it should be made to the very top. If this does not happen, then the internal corrosion of the pile and reduction in the duration of its service can form.
