Bored piles are actively replacing the usual foundation supports. The range of application of these piles is very high, they can be used in the construction of multi-storey buildings in an industrial way, as well as in the construction of private houses.

Bored piles are a modern type of foundation support, made in the form of monolithic cylindrical structures with a reinforcing frame of rigidity.

Construction of high-rise buildings

In the construction of multi-storey buildings, a special technique is used for the manufacture of a bored foundation, with the help of which a hole is drilled for a pile in the ground. After that, a welded frame made of reinforcing bar with a diameter of 12 mm is inserted into it. Next, the pile is poured with cement mortar and wait until it dries. This technology is safe for surrounding houses in the case of compaction building, as it is not associated with work that leads to active vibration of the soil and the destruction of loose layers.

Construction of private houses

Bored piles are also widely used in the construction of private houses. Based on the use of this method of laying the foundation, the popular TISE technology is being built, which uses a pile-strip foundation.

In private construction, hand drills or motor-drills are used for drilling wells. Unlike industrial construction, all work is done by hand. You need to pay attention to the properties of the soil, if you are drilling a hole for a pile in easily crumbling soil, then you need to install concrete formwork. A reinforcing cage is installed in the drilled hole and only after that concrete is poured.

Features of bored piles

In private construction, bored piles are laid at the depth of soil freezing and a waterproofing coating is made of roofing material or cellophane, and in industrial construction, hydraulic engineering devices for groundwater drainage are used.

An important role in working with bored piles is played by the diameter of the used reinforcing bar, which bears the main load. The diameter of the piles ranges from 150 to 600 mm, and the diameter of the reinforcement used is from 6 to 16 mm. All these indicators affect the bearing capacity of the piles, which are installed under the load-bearing walls and at the corners.

In private construction, the use of bored piles significantly increases the cost savings when laying the foundation, since it does not need to be dug and poured to the full depth of soil freezing. With the correct calculation of bored piles, the foundation does not lose its bearing capacity at all; moreover, it is possible to increase the bearing load by using thicker reinforcement bars and reducing the distance between the piles.
