Description

The drilled pile is intended for use in a transporter, housing estate, and pristine tunnels. In Enoeti tea - and pile-building industry.

Pile foundations, which provide the possibility of erecting buildings and structures on soils with insufficient bearing capacity, have become widespread in the practice foundation of world foundation engineering. According to the method of installation into the ground and to the "structural features, many teshuv piles are distinguished. These, for example, include the worst piles: reinforced concrete., Wooden and steel. Driven piles are immersed into the ground without excavation using hammers, vibration dampers, vibration-pressing and pressing devices (1} “Swishle foundations. Building norms and rules. 2.02.03-85. USSR State Committee for Construction, Moscow, 1986., str. the advantage of driven piles is their large bearing capacity, for example, when a pile is immersed in gravel soil to a depth of 10 meters, the calculated resistance under the lower end of the driven piles is 1050 TcW (1, table 1).a large stratum of soft soils lies in the place of foundation installation, and the immersion of long piles is inconvenient or impossible, instead of a solid pile, it is higher than a pile. L p. 22).

Also known are reinforced concrete drilling piles arranged in the soil by filling a drilled well with concrete mixture and installing reinforced concrete elements (1J, p. 2). The advantage of drilling piles is that they can be made of almost any length, and right in the construction of the facility. One of the drawbacks of drilling piles is their relatively low bearing capacity compared to a driven pile. For example, when installing piles in gravelly soil at a depth of 10 meters, the calculated resistance under the lower end of the drill pile is only 135 (1, table 7), while for a driven pile this figure is 1050, all other things being equal.

The proposed utility model - a bored pile - is aimed at increasing the bearing capacity of a drill pile.

The goal is achieved by forming a zone of overlap between the lower end of the drill pile and the upper end of the driven pile. With the lower end of the drill pile along the outer contour covers the upper end of the driven pile. The result is a solid, bored pile that combines technical

characteristics of both drilling and driving piles. Due to the fact that the vertical force acting on the drill pile is transmitted to the driven pile, the bearing capacity of which is higher than the bearing capacity of the drill pile, the bearing capacity of the entire bored pile is increased.

The bored pile device is shown in the figure, where 1 is a driven pile, 2 drilling pile, and the overlap zone. 2

A boring pile, including a driven pile and a drilling pile, characterized in that the lower end of the drilling pile covers the upper edge of the driven pile along the elevated contour, forming a zone of overlap.
