Technology

Dynamic development of the construction industry in Russia and an infill construction in major cities require the use of new high-tech methods in the field of underground construction works.

TechnologyBore cased piling

Bored piles are a cylindrical welded structure, which consists of longitudinal corrugated reinforcement of class A1-A3, connected by transverse round lintels. The diameter of the bars is determined by the size of the structure.

Technology selection conditions
The technology of bored piles with casing is one of the safest in modern construction. It is applied:

on the territory with very dense buildings;
on landslide soils and areas with a significant slope;
in areas with difficult geological conditions (for example, increased seismicity).

The casing pipe used during installation ensures the safety of pile work of any complexity. It allows you to block the horizons of floating soils and control the parameters of the well.

The technology of drilling piles with casing is universal and can be used when laying the foundation for buildings of various architecture and purpose. This method is used for residential buildings, industrial facilities, administrative, commercial and other structures. Due to its high reliability, it is especially in demand in transport and bridge construction.

Technologies

The technology of drilling piles with a casing pipe is used for:

watered soils (the pipe protects the well from the collapse of the walls during drilling);
solid soils (rocky);
at depths up to 45 meters.

The use of a casing pipe allows you to cover the horizons of quicksand soils, ensure the safety of piling operations, control the parameters of the drilling well, guarantee high quality of filling the well with concrete in difficult geological conditions.
This type of piles is the most popular among transport construction, bridge construction due to its high reliability.

Technology advantages

Advantages of bored piles

Low noise level. This allows you to work at night. When installing piles with a casing pipe, there is no vibration, so this technology can be used near residential buildings.

Economy. The structure is made directly on the construction site using monolithic concrete. The total cost of a pile with pipes will be less than the price of a finished concrete block of the same size.

Reliability. The bearing capacity of bored piles is higher than that of driven piles. Each structure can withstand a load of up to 400 tons (up to 15 tons per 1 running meter). The use of pipes eliminates the formation of necks in the well from a mixture of soil and water.

Versatility. The device of bored piles with the use of casing pipes can be made on any type of soil: sandy, gravel, loose, dense and others. Working with this method allows you to perform tasks in rocks, for example, to drill and extract boulders.

Efficiency. This technology uses compact and mobile equipment that is easily delivered to the construction site. The number of installations is determined by the required rates of laying piles. At the same time, the cost of work and their high quality remain unchanged.
