The latter is in the form of a diesel hammer. In the casing pipe at the top of the fixed reference-boot space. On the last fixed ferrule diesel hammer, and its piston through the United traverses a rigid rod connected with the piston rod. The stamp is placed in the cavity of the guide tube with the possibility of reciprocation. Moreover, the lower edge of the casing is located above the lower edge of the siege of the pipe. 8 Il. The invention relates to the construction, in particular, to the pile Foundation.Known installation for the device broadening piles, including the casing and impact device comprising a weighted body with the lower drum part, through which the cable is connected with the hoisting mechanism, and the device broadening Spa is 1] a Disadvantage of the known installation is low productivity, due to the need of lifting and fixing weighted body before filling each of the next portion of the mixture, and the need for multiple cycles of lifting and dropping to trebovaniya each portion of the mixture that takes a long time because of the limited speed of lifting of the lifting mechanism.Closest to the invention to the technical essence is the setting for the device broadening piles containing the casing and coaxially placed in the cavity with the possibility of reciprocating movement of the stamp with the drive  a Disadvantage of the known installation is low productivity.The technical result of the invention to improve the performance of installation for the device broadening piles, is achieved by the fact that the latter, including the casing and coaxially placed in the cavity with the possibility of reciprocating movement of the stamp with the drive is equipped with a guide tube coaxially installed with the ability to regulate the vertical position in the cavity of the casing and education space between them for feeding granular mixture and the bottom edge of the guide tube above the lower edge of the mounted actuator stamp made in the form of diesel hammer with a piston through the United traverses rigid rods connected with a stamp placed in the cavity of the guide tube and ferrule diesel hammer rigidly mounted on the loading platform.In Fig. 1 shows a General view of the installation with partial cutout, Fig.2-5 sections a-a, b-B, B -, G-G in Fig.1; Fig.6 immersion installation before the broadening of Fig. 7, 8 scheme dispensing granular mixture and education broadening.Installation for the device broadening piles includes the casing 1, provided with a rigidly fixed by means of the ribs 2 of the musculo-boot area 3, and the ribs 2 are the projections 4 on the inside of the casing 1 and projecting upward of the support part 5, rigidly connected on top of the support table 6, to which the bolts 7 are attached ferrule 8 of the cylinder 9 diesel hammer 10.In the cavity of the casing 1 coaxially mounted guide pipe 11, provided with a locking ring element 12, is fixed in the upper part of the guide pipe 11 on the bolts and resting in a project position on the tabs 4 of the ribs 2, which allows you to adjust the vertical position of the guide tube 11 and service guide pipe has a pipe space 15 to move it loose concrete mixture 16 of the loading Bay 3 to the bottom-hole zone 17.Percussion device has an actuator in the form of a diesel hammer 10 that is installed in the holder 8 on the supporting table 6 coaxially with the casing 1 and the guide pipes 11, and stamp with the rod 18 with the lower drum part 19 and placed in the guide tube 11 with the possibility of reciprocating vertical movement. Moreover, the stem 18 of the stamp is rigidly connected by means of a traverse 20 and rigid rods 21 with the piston 22 diesel hammer 10. To download loose concrete mixture into the cavity between the casing 1 and the guide pipes 11 in the boot area 3 includes loading window 23. To prevent the dry mixture into the cavity of the guide tube 11 in its upper part there is anther 24 of wood or metal.The device operates as follows. The installation Assembly is mounted on a standard swaebe and before immersion in water-saturated soil on the project depth attenuation of the casing 1 from the bottom to the wooden strip 25 in order to avoid the ingress of soil into the cavity between the casing 1 and the guide pipes 11. In the lowest position of the drum part 19 of the stamp does not get to a wooden strip 25. The impact of diesel hammer 10 when idle mixture casing pipe 1 is transmitted to the pipe, resulting in the surface of the earth. Then through the feeding window 23 into the cavity between the casing 1 and the guide pipes 11 is loaded bulk of the concrete mixture 16 to the extent necessary for the formation of the broadening of a given diameter. The shaft 18 together with the piston 22 diesel hammer 10 raised to its extreme upper position, resulting in dry concrete mix is poured from the cavity between the pipe under the lower edge 13 of the guide pipe 11 to the extent determined by the height of its location relative to the bottom edge 14 of the casing 1. Thus is the dosage of the dry mixture in each cycle of trebovaniya. Then, the rod 18 being thrown lifting mechanism swaebe, thereby producing blow formed in the lower part of the casing 1 serving granular mixture 16 and utrambovyvaya this portion of the adjacent soil. Portions of granular mixes and the height of the lifting rod 18 are correlated so that the kinetic energy of the falling rod 18 and connected to a piston 22 diesel-hammer 10 has sufficed not only to utrambovyvaya dry concrete mix, but enough to ignite the compressed fuel mixture in the cylinder of a diesel hammer 10. In the combustion chamber of the diesel hammer 10 is an explosion of the compressed combustible mixture in which the piston 22 are given stranstvo another portion of the granular mixture 16 under the lower edge 13 of the guide pipe 11. The rod 18, having reached its extreme upper position, again falls down and the cycle repeats. The process of trebovaniya dry concrete mix continues within the estimated time, which is determined on the basis of the total mixture volume one portion and frequency of strikes diesel hammer, whereupon the installation for the device broadening is extracted by means of a lifting winches swaebe, and formed in the well immersed precast pile shaft, for example by vibropogrujatel, or concreted. INSTALLATION FOR the DEVICE BROADENING PILES containing the casing and coaxially placed in the cavity with the possibility of reciprocating movement of the stamp with the actuator, characterized in that it is equipped with a guide tube coaxially installed with the ability to regulate the vertical position in the cavity of the casing and education space between them for feeding granular mixture to the bottom edge of the guide tube above the lower edge of the casing in the upper part of which with rigidly fixed thereto reference-load ground mounted actuator stamp, made in the form of diesel hammer, with the piston through the United traverses rigid rods connected with schnoy site.
