For a long time in construction technologies, screw piles were used only for the construction of bridges, as well as fixing structures on unstable types of soil (swamps, glaciers, etc. p.At present, more and more often developers of structures of residential buildings and buildings of a larger scale turn to the use of screw piles. With their help, even small cottages are built for giving. Piles last a long period of time, reliably replacing the foundation.
The foundation, being a supporting structure of the structure, can cause the collapse of part or the entire building if its organization is incorrect. It is very important when laying the foundation to take into account the type of soil, the depth of groundwater, and many other factors. On problem soils, the standard strip foundation is short -lived, so experts recommend laying a pile -type foundation for a greater stability of the building.
Rifle piles to lay the foundations of buildings have been used since 1985. It was this year that the standards for the manufacture, installation and operation of screw piles were developed and calculated.
Screw piles are made in the form of a steel pipe with a screw at the bottom. For better entry, the end of the pipe is performed either in the form of a cone or an acute cut. Conical pile is good in that in uncomfortable places or in the absence of the necessary equipment it can be twisted manually. Pile should be immersed at least 1.5 meters into the ground. The exact depth of immersion is calculated by architects and construction engineers at the stage of designing the building. Ordering screw piles can be implemented on the site of the base of the base
The following points are especially worth noting. The pile foundation is installed much faster than the usual. If desired, it can be dismantled or supplemented and completed by the building based on it. Screw piles are suitable for all types of soil except rocky breeds and save up to half of the funds when laying the foundation.
