To quickly build a country house, without waiting for the final drying of the soil after it thawed, it is necessary to apply the foundation from the screw piles.
In the spring, it is problematic to carry out the installation of the foundation, due to the increased humidity of the thawed soil. Its natural drainage will require a lot of time, which will lead to an increase in the construction time, and the conduct of measures to drain it, will increase the cost of construction itself.
Under soil conditions, it is rational to use the foundation from screw piles. This advanced technology for the installation of foundation bases allows the construction of objects on soils with low bearing capacity and high humidity. It has a low labor intensity of the construction of this foundation and allows you to reduce its construction time. This type of foundation is not suitable for construction in rocky soils.
The main measures to arrange the foundation of St. Petersburg from screw piles are the following. After the development and approval of the project of the house, it is binded to the construction site. The breakdown of the axes of the pile field and marking of the zavi screwing are done. A trial screw to one screw pile in the ground is produced, to compare the results with the project. Next, everything provided for by the project, piles. This process takes a short time. Parts of the piles protruding above the soil are trimmed at one mark, and their cavities are poured with concrete to create the rigidity of the structure and exclude corrosion inside them. A monolithic grillage is arranged on them, which will be a support for the walls of the house.
The practice of using this type of foundation in construction shows their successful operation in difficult soil conditions.
