The proposed method and device relate to the field of construction and can be used in the construction chosen to replace concrete-frame structures in the soil, in particular in the construction of retaining walls.

The known method and device for erecting ramming piles, including the vibration exciter with buried in the ground hollow composite body of the two longitudinal sections. The vibration exciter creates vibrations along the longitudinal axis of the housing and the components of its longitudinal partitions have the opportunity to move relative to each other (ABT. mon. The USSR №1236062, BI No. 21 from 07.06.86,, CL E 02 D 7/26).

The known method and device construction ramming piles, including the vibration exciter, which in the soil is immersed casing pipe or duct, the lower end of which is blocked by a detachable Shoe. After immersion of the pipe or duct to the required depth and fill the cavity with concrete, pipe or duct begin to extract and separate from them Shoe at a fixed distance, not exceeding the height of the layer of concrete mixture, perceiving the vertical vibration of the Shoe. Then make further extraction pipes or trunking. Through the space formed between the Shoe and the pipe (duct) concrete mixture flows from the pipe or duct and fills the cavity in the ground. Thus, in the ground form od the night cylindrical or prismatic supports (ed. mon. Of the Russian Federation No. 1761868, BI No. 34 from 15.09.92,, CL E 02 D 5/38).

The disadvantage of these methods and devices is their limited technological capabilities, i.e. the impossibility of creating in the soil solid chosen to replace the long-walling.

The closest technical solution of the present invention is a technique in which the soil using vibro sequentially dipped into the castle, and then vibrating remove inventory items with simultaneous filling of the cavity in the ground hardening material (Mechanization of construction, No. 9, 2000 Ore, Emily, Iwholename. Domestic high-performance vibratory pile driver to perform special operations in the ground. C. 2-5).

Closest to the invention is a device for the erection chosen to replace soil-bearing structures, including the vibration exciter and at least two hollow body, within each of which, with the possibility of longitudinal displacement posted by draught, connected in the bottom part with the Shoe and having stops. On the outer sides of the walls of each body is hard-coded guides and grooves, allowing the buildings to communicate with each other in both longitudinal and transverse planes. By consecutive vibraphone, fill with concrete mix and vibroisolating hollow to the of Busov, connected with guides and grooves in the ground form a continuous concrete wall of uniform rectilinear cross-section, embedded in the ground at a constant value (RF patent No. 2173373, BI No. 25 from 10.09.2001,, CL E 02 D 5/34).

The disadvantage of these methods and devices is their limited technological capabilities, i.e. creation in ground concrete wall whose cross section along the entire length has a small area, which reduces the ability of the wall to absorb torque from the forces of resistance of the soil when working wall as a retaining wall, as well as a negative influence in the operations of the dynamic impacts on nearby buildings and structures.

Task to be solved by the present invention is directed, is the expansion of technological capabilities and increase the efficiency of the method and of the device by increasing the resistance moment of the cross section of the wall and increase its ability to absorb torque from the forces of resistance of the soil, and the reduction of dynamic effects on the Foundation soil immersion elements.

The method of construction in the soil chosen to replace-walling includes sequential vibration immersion in the soil inventory items, mating among themselves, and their subsequent vibration retrieve the increase with simultaneous filling of the cavity in the ground with concrete. Use inventory items, made in the form of profiled elements longitudinal fence and profiled elements uprights having in the lower part of the sash closed when submerged in the ground and opened by means of flexible connections when removing elements from the soil and the supply of concrete mixture. Profiled elements longitudinal fences have a length less than the length of the profiled elements of the vertical posts, which when immersed press to a greater depth than the profiled elements of longitudinal barriers. First vibroport profiled longitudinal element of the fence, and then tightly match with him by sending shaped conductor element upright and carry out its vibrophone. After that load the concrete mix in the profiled longitudinal element of the fence and his vibroisolation with open shutters. The extracted element vibroport in the following position with adjunction to the previous in the soil profiled element vertical racks. Then load the concrete mix in the profiled element upright, his vibroisolation with open doors and vibroport the extracted item to the next position with the simultaneous docking with the previous profiled e is a COP longitudinal fence using the guide conductor. Next, repeat the immersion of items in inventory.

The method of construction in the soil chosen to replace-walling consists in the following. On the hook polyspastny crane system 1 or copra hung the vibro-2, which is rigidly fastened to the movable carriage 3, located on the vertical guide rail 4. With the help of hydraulic capture profiled longitudinal element fences 5 fasten with vibro-2. Under the action of vibration and pressing the efforts of the profiles is consistent element longitudinal fence plunge into the ground to the design elevation through the guide conductor 6. After this profiled element vertical posts 7 match with the ground profiled longitudinal element fences 5 using the guide conductor 6 and repeat the immersion similar to the first, but at greater depth. Then a flexible connection 8 in the profiled element longitudinal fence 5 free, grabbed her by the upper hinge 9 and thereby provide an opportunity to open the door 10, a profiled longitudinal element of the fence from the top load of the concrete mix and begin with vibration to extract it from the soil. Under the action of gravity of the concrete mix is the opening of the valves 10 and 11, the concrete mixture flows from the element and fills formed by immersing the cavity in the ground. After extraction, the profiled longitudinal element fences 5 on its surface is immersed in the following position with simultaneous adjunction to the previous in the soil profiled element upright support 7 by means of the sending conductor 6. Then a flexible connection 12 profiled element vertical racks free and hook over the top of the loop 13 and produce a vibration removing the profiled element vertical posts with simultaneous pouring of the cavity in the ground. After extraction, the profiled element vertically in the front 7 on its surface is immersed in the following position with simultaneous docking with the previous in the soil profiled longitudinal element fences 5 using the guide conductor 6. Then the concrete structure reinforced by vibraphone vibrator low power in freshly placed concrete reinforcement cages or grids 14. Thus, in the ground form a continuous chosen to replace-enclosing concrete wall that can act as retaining walls, elements of which have different depth and increased in the zones of the cross-sectional area.
