The invention relates to the field of construction, and in particular to equipment for construction of piles in the soil to increase its load carrying capacity in the place of construction of various buildings and structures, as well as means of improving bearing capacity and strengthen the soil, for example, in prazole closest to the technical essence is a device for the manufacture of printed piles, containing casing pipe buried in the ground with the help of a vibration exciter mounted on its upper end with a support, and overlying the cavity of the casing losing a Shoe on its lower end (SU 1761868 A1, E 02 D 5/38, 15.09.1992).

Also known construction ramming piles, made in the form placed in the array of ground extended, preferably vertically oriented, concrete or reinforced concrete body, the bottom of which rests through the Shoe on compacted in his vibraphone soil layer and, preferably, has a widening (SU 1761868 A1, E 02 D 5/38, 15.09.1992).

Known construction, using the method of vibraphone casing with subsequent supply in her concrete mixture and removing the casing, does not exclude the possibility of a reduction in the strength characteristics under construction ramming piles due to leaking joints in the process of immersion lose a Shoe and casing, which may lead to the leakage of groundwater into the cavity of the casing and to the inevitability of concrete piles through its displacement, which will adversely affect the quality of the piles. In addition, the process of creating a core of compacted soil moved during vibraphone area of the working surface of the Shoe and does not take into account possible changes of category, the moisture content and density of soil, which can lead to a decrease in the size of the nucleus or in the end - to puncture a kernel Shoe.

The objective of the present invention is to improve the quality built ramming piles, increase its carrying capacity by optimizing the process of formation of the soil cores under a lost Shoe, as well as reducing the complexity of the process of concreting piles.

This is achieved by the fact that:

device for the manufacture of printed pile contains steel casing pipe with mounted in the upper part of the device for mounting and vibro Shoe at the bottom, according to the invention a device for mounting vibro made in the form of a reinforcing ring, covering the upper part of the pipe, and attached to it by welding, connected with casing pipe, and below the reinforcing ring, a reinforcing plate having a plan axisymmetric shape, preferably diamond or circle, whose plane is perpendicular to the longitudinal axis of the casing and the ribs in the form of, for example, trapezoidal plates, connecting the reinforcing ring and the reinforcing plate and symmetrically relative to the longitudinal axis of the pipe, and the Shoe is made which would and to the top plate loose Shoe attached guide ring inner diameter which exceeds the outer diameter of the casing, at least to the extent of thickness placed between them during installation of the casing strip of elastic material, preferably rubber, or outer diameter which is less than the internal diameter of the casing by the same amount. In addition, the gasket may be made with a minimum linear length or width of her facing the pipe surface, not less, respectively, the sum of internal or external diameter of the guide ring of the Shoe, and twice the height of its walls. The gasket is placed between the casing pipe and the walls of the guide ring with the formation of the protruding beyond the contour of the ring its edges;

drilled pile is made using the above-described device and its concrete or reinforced concrete body is supported on a guide ring lose a Shoe through a lining of elastic material, preferably rubber or at least through a part of it. When the gasket may cover at least part of the perimeter of the lower part of the body pile height not lower the height of the walls napravlyayus quality built ramming piles and its bearing capacity due to the optimization process of the formation of a soil core under a lost Shoe, as well as reducing the complexity of the process of concreting piles.

The invention illustrated by the drawings, where Fig.1 presents a General view of an apparatus for manufacturing printed piles of Fig.2 is a view along a-a in Fig.1.

Device for the manufacture of printed pile contains steel casing pipe 1 with mounted in the upper part of the device for mounting the vibratory pile driver (not shown). Device for mounting vibro made in the form of a reinforcing ring 2, covering the upper part of the pipe 1 and is attached thereto, for example, by welding, and is connected to the casing tube 1 and below the reinforcing ring reinforcing plate 3. Plate 3 has in terms of an axisymmetric shape, preferably diamond or circle, and the plane perpendicular to the longitudinal axis of the casing 1. Device for mounting vibro made with ribs 4 in the form of plates, for example trapezoidal connecting the reinforcing ring 2 and the reinforcing plate 3. The ribs 4 are symmetrically located relative to the longitudinal axis of the pipe 1. The lower part of the casing is equipped with a lost Shoe, made in the form of a plate 5 greater area than the area of the outer circumference of the casing 1, and it increases the outer diameter of the casing 1, at least on the value of thickness is placed between them during installation of the casing pipe 1 gasket 7 of elastic material. The gasket 7 is made, preferably, of rubber, for example, microporous. The outer diameter is 6 less than the internal diameter of the casing 1 by the amount of the thickness placed between them during installation of the casing pipe 1 gasket 7. In addition, the spacer 7 may be performed with the minimum line size - the length or width of her facing the pipe surface, not less, respectively, the sum of internal or external diameter of the guide ring 6 of the Shoe, and twice the height of its walls. The strip 7 may be made of any shape and placed between the casing pipe and the walls of the guide ring with the formation of the protruding beyond the contour of the ring its edges. Printed pile (not shown) is performed using the above-described device and its concrete or reinforced concrete, at least part of its length, the body is supported through a lining 7 of elastic material, preferably rubber, for example, microporous, or at least through part of it, to lose a Shoe. When the gasket 7 may cover the lower part of the body of the pile, at least on part of its lane is aetsa as follows.

The vibro together with the basic machine with a guide for him the mast is installed on the place of education ramming piles. Steel pipe 1 is moved from a horizontal to an upright position above the established ground losing a Shoe at a distance of approximately 0.5 m On napravlyayus ring 6 lose a Shoe placed the gasket 7 and the lower pipe 1 with the formation of a dense waterproof connection. To the upper part of the tube 1 at the location of the ribs 4 attach the vibration exciter. During the operation of the vibration exciter is created aimed disturbing power, through which and by using a counterweight mounted on the guide base of the machine carriage carry out the immersion of the casing pushing lose a Shoe. The diameter of the lost Shoe exceeds the diameter of the casing, which removed the side friction of the pipe 1 on the ground. Under the Shoe in the immersion process formed the core of compacted soil under optimum conditions of the dip pipe 1 is moved together with the Shoe in the depth of unconsolidated array. Because of the different properties of soil, the depth of the array, including humidity, the efficiency of compaction conventional Shoe is reduced, the Odile shocking pulses, transmitted by the vibration exciter on the pipe 1, is transmitted to the Shoe with a certain time delay, which allows to increase the pulse duration and changing the rheological properties of the soil to ensure its effective seal. In addition, the gasket 7 prevents the cavity filling pipe 1 ground water, resulting in concreting piles carry out concrete mixture of controlled composition. Before concreting process or during it in the cavity of the pipe 1 is installed, if necessary, the valve piles. In the process of concreting the casing removed for reuse. The pile is thus in the form of a concrete body, installed on losing the Shoe through the elastic strip, while the Shoe is located on compacted soil core, the diameter of which in cross-section is about three diameters of the plate 5 of the Shoe.

The proposed technical solutions allow to increase the pace of work in flooded or saturated soils while complying with the required quality of the piles.
