What operations does the installation of screw piles consist of?

The reliability of any construction project is determined not only by the quality of the materials used, but also by the accuracy of fulfillment of technological requirements during work. For the correct installation of screw piles, an amateurish approach is not acceptable. This requires professional knowledge and practical experience - the technology is based on full preparation of the process and constant monitoring during its implementation. That is why clients with experience prefer professional services, which can always be ordered from pile structures factories.

Installation procedure

During the preparation period, test drilling at the future construction site is mandatory. The operation allows you to study the structure of soils and their composition, examine the topography, the presence or proximity of reservoirs and hydrocarbons. The next step is to perform calculations, on the basis of which the manager selects steel supports (by size and design) that are most suitable for a specific project. The process then takes place in several stages:

• immersion of pillars to the required depth;
• trimming the tops of trunks in a horizontal plane;
• pouring CPS into trunks to reduce the risk of corrosion;
• welding of caps - metal platforms that cover pipes and provide support for further construction;
• piping with rolled metal (channels, angles, corrugated pipes) - according to the client’s order;
• applying anti-corrosion primer-enamel to welding areas.

During the installation, at each stage, the position of the pillars, heads, and strapping is constantly monitored - using a level or automatically (when using special equipment).

Possible twisting methods

Depending on the volume of services, the standard size of the screw piles, and the complexity of the conditions on the site, builders use one of 2 methods for screwing metal supports:

• Manual. To carry out the operation, 3 workers are required: 2 for twisting using a lever (crowbar) threaded through the eyes on top of the barrel. The third worker controls the vertical position of the pillar with a level. The method is used for light and medium-sized objects with a small amount of SHS of a small standard size, with low soil density.
• Mechanized. The use of special equipment requires an experienced operator, but allows you to carry out work with maximum accuracy and 2 times faster than manually. The mechanized method is used on large projects, when it is necessary to install heavy poles of large sizes, as well as on dense soil.

The use of special equipment makes the service somewhat more expensive, but most customers prefer to pay for this type of work, since it speeds up the completion of construction and is more economically profitable.

Advantages of pile technology

When choosing a foundation construction method, each client weighs the pros and cons of each type. This technology has several undeniable advantages:

• High construction speed. No other method allows you to make a foundation in 3-5 days (for fences and small objects - 1 day).
• Versatility. Such a foundation will be static on a steep slope, with weak soil, near a reservoir.
• Work is carried out at any time of the year. Low temperatures are not an obstacle, since the propeller dives below the freezing point. The design is not subject to the forces of frost heaving.
• Life time. For factory products manufactured using technology, operation is guaranteed for 80-100 years.

Another significant advantage is cost savings. For those who need an affordable cost of a pile foundation in St. Petersburg , it is advisable to contact the factory. Here you can purchase products at a minimal markup and order professional installation.
