Foundation works

Pile elements can be driven in various ways. • One is manually using levers, where the force depends on the lever's length. However, this method is limited by pile size and soil type, and is characterized by low productivity. • The second method is using manual electric or hydraulic pile drivers, which are also limited by pile size and soil type, but productivity remains average. • The third option is to use small-sized mobile pile drivers, which are limited by support size and soil type, have insufficient productivity, and require special transport for delivery to the site. Excavator-Mounted Pile Drivers Pile driving is accomplished using attachments on special equipment, such as pile drivers, hydraulic rotators, or hydraulic pile drivers. The main purpose of these devices is to drive screw piles to the required depth during foundation construction for various structures. Any hydraulic pile driver can be used as a pile driver if it is carefully selected based on the tech...

Screw piles are a sought-after solution in the construction industry due to their versatility, ease of installation, and optimal reliability. They are widely used in the construction of pile foundations for various structures, such as houses, bridges, fences, and barriers. These pile elements are particularly effective in dense soils and in frozen ground conditions. The installation of screw pile supports involves several key stages, each requiring specialized equipment. The use of these pile supports allows for the secure anchoring of both shallow and deep foundations without disrupting the natural soil structure. Their use is especially important in permafrost soils, as excavation and concreting are eliminated. A distinctive feature of the screw pile support design is their high load-bearing capacity, which is effective under both compressive and tensile loads. Installation Stages 1. Preliminary Work and Planning Before installation, a thorough engineering survey must be ...

Screw piles play a vital role in modern construction, providing significant strength and adaptability to various climatic conditions. Although some manufacturers often claim service lives of 120 years or more, practical conditions and various factors can lead to deviations from these estimates. Main Factors Affecting the Service Life of Screw Piles 1. Effect of Material and Corrosion: The longevity of screw piles is primarily determined by the corrosion rate, which in turn depends on the quality of the steel and the corrosivity of the soil. The service life of screw piles is affected by both chemical and electrochemical corrosion, while the corrosion rate is influenced by pH, moisture, and soil type. 2. Physical Characteristics: The thickness of the pile blade and shaft is critical; even a slight increase in these dimensions can significantly extend the service life of the pile. Installation depth also affects service life, as deeper installation can slow chemical corrosion. 3. P...
