Description

SUMMARY OF THE INVENTION The present invention relates to a plant for the production of on-site concreted piles allowing the use of a single pressure reservoir for different types of pipe length.

Several devices are known for the production of. site of concrete piles. It is known to have a single tube device below the upper edge of which a pressure reservoir is provided, a vibration ram being attached to the pipe above the pressure reservoir.

Furthermore, there is known a device consisting of a bundle of two tubes, one of which is known as a " • The scoop pipe is used to squeeze and carry soil to the surface. the filling pipe serves to push the soil and fill the hole after the pushed and cut soil with a concrete mixture, the bottom is provided with a push tip, it is connected to the pressure reservoir on the upper part of the collecting pipe. Above the pressure reservoir, a vibrating ram is prepared for the collecting pipe. The disadvantage of said devices is that the oven resp. The bundles of tubes form a non-disassembled unit of considerable dimensions with the pressure reservoir, resulting in transport problems. In the production of piles of different lengths, the pipes need to be shortened, or welded to lengths to the required size, or the whole other equipment with the necessary lengths of pipes used.

Also known are devices in which the pressure reservoir forms a separate part and is connected to the pipe or pipe. a bundle of two pipes attached by means of a flange. The disadvantage of these devices is that they use a flange of complex shape, which is different, using one pipe and a bundle of two pipes. When connecting the bundle of two pipes to the pressure reservoir, it is necessary to install a baffle in the central pipe of the pressure reservoir, which directs the flow of concrete mixture into the filling tube and fill the space between the baffle and flange with polystyrene.

The drawbacks of the prior art apparatuses eliminate the apparatus for the production of in situ concrete piles according to the invention essentially by attaching a pipe 7 or bundles of two pipes 4 to a pressure reservoir 1 (FIGS. 1 and 2) which is attached to the vibratory pile 2. and 5 by flanges 3 of simple circular shape. The use of a circular flange for the sleeve of the two pipes 4 and 5 is made possible by the so-called " the scooping tube 4 used for cutting out and bringing the soil to the surface is closed in the upper part by an inclined partition 6 and the second so-called. the feed pipe 5 serving for the squeezing of the soil and the filling of the hole after the squeezed and fertilized soil with the concrete mixture is topped into the collecting pipe 4 above the partition 6, below the flange 3.

The advantages of the device according to the invention lie in a simple delivery, which can be disassembled into lighter units. The circular flange is uniform for the pressure reservoir, one pipe and the hump of two pipes, which also simplifies the shape of the pressure reservoir compared to

Claims (2)

SUBJECT Apparatus for the production of on-site piles, characterized in that it consists of a pressure reservoir (1) to which a vibratory ram (2) is frontally attached and one tube (7j or a bundle of tubes (4) and (55) which are an annular flange (3j) attached to the pressure reservoir (1j), with at least two tubes (4) and (5), a so-called pick-up tube (4) serving on a different design. a set of individual tubes and a plurality of tubes of different lengths can be used in the pressure reservoir. BACKGROUND OF THE INVENTION, the cutting-out and drawing of soil to the surface is closed by an inclined partition (6) in the upper part below the flange (3) and the second so-called. a feed pipe (5) serving to thrust the soil and to fill the hole after the shredded and cut soil with a concrete mixture is mouthed into the collecting pipe (4j) above the partition (6J).
