Bored piles
The company "Installation of Piles" provides services for drilling wells for bored piles. To perform the work, we use a highly productive BM-811 pile driver, which creates wells to a depth of up to 12 m and a diameter of 150 to 500 mm.
This page presents information about bored piles. We will consider cases when their arrangement is necessary, the technology for mounting bored supports and the features of drilling for piles with casing. The method of tying bored piles with reinforced concrete grillage will also be given.
One of the existing options for pile foundations is the foundation on bored piles. As a rule, bored piles are built where the use of pile driving is impossible for any reason.
Classification and design of bored piles
Bored piles- reinforced concrete structures, the well for the installation of which is formed by drilling. A typical design of a bored support consists of two elements - a concrete body and a reinforcing cage.

The process of arranging piles using CFA technology is as follows:
- A well is being developed to the design depth (if necessary - under the protection of the casing pipe);
- Concrete is injected into the well through the auger, the column is systematically removed as the cavity is filled;
- An armored carcass is installed in a concrete-filled well with the help of a vibratory pile driver.
Bored piles: pros and cons
If the construction site is located in an area where the use of technologies that cause the slightest vibration of the soil, bored piles, as a rule, cannot be dispensed with.
However, the technology of their manufacture, although it has been worked out, is rather laborious and requires precise observance. The level of professional training and experience of the employees performing these works must be appropriate, since this process, depending on the condition of the soil at the site, has a lot of nuances.
An excellent alternative to the manufacture of bored piles is leader drilling for piles. The price of drilling one running meter of a well is from 200 rubles, and depends on the condition of the soil.
Our equipment allows, without changing position, to immediately plunge piles into drilled wells. What is the advantage of such a method?
- Such immersion does not create a high level of vibration impact on neighboring buildings.
- Allows you to build reliable pile foundations even in urban areas in dense buildings.
- Provides accurate calculated pile driving in difficult soils (permafrost soils, areas with a high level of groundwater, soils with quicksand and lenses, etc.).
In addition, we produce leader drilling for screw piles and their installation. Contact us, our experts know and love their job!
