The invention relates to a method of manufacture a reinforced anchor post made of in-situ concrete, which is brought in by means of a jacking pipe is closed by a pile shoe remaining in the ground and has ribs on its outer wall, which create helical cavities in the ground, which when pulling the propulsion pipe be pressed with hardening building materials.

A method for producing reinforced anchor piles from in-situ concrete is already known which ribs are arranged on the outer wall of the propulsion pipe, so that when the propulsion pipe is driven in Helical cavities arise in the ground. When pulling the jacking pipe this will Propulsion tube rotated so that the ribs slide in the helical cavities and their Maintain dimensions and shape so that they can be filled in by the building material.

The invention is based on the object of producing an anchor post with helical Bulges on its surface especially necessary when introducing the propulsion tube Reduce effort. Furthermore, the on the outer wall of the jacking pipe arranged ribs contribute to maintaining the driving direction.

The solution to this problem is seen according to the invention that the on the outer wall of the propulsion pipe arranged ribs the helical cavities only when pulling the propulsion pipe produce.

By means of the invention, the propulsion pipe is introduced, which is connected to the longitudinal axis of the propulsion pipe parallel ribs, with little effort.

When the driving pipe is pulled, the building material follows the ribs, which only now follow the helical ones Cut cavities in the ground immediately so that the cavities are in their given shape are not yet changed. Furthermore, the creation of the cavities when pulling the jacking pipe allows that the entire pulling device can be supported against the ground, whereby the device can be kept in their dimensions easier than it is when producing the cavities would be required when introducing the propulsion pipe.

Using the exemplary embodiment shown in the drawing the invention is explained in more detail below. It shows

Fig. 2 shows the device according to Fig. 1 in plan

ao sees

F i g. 3 the propulsion pipe tip in view and in section,

4 shows the guide plates for the propulsion pipe. The pile shoe 2 and the propulsion pipe 1 with the

he ribs 4 are known per se as a unit Driven into the ground by pressing, ramming or shaking. The propulsion pipe 1 can thereby can also be composed of several parts. In the example shown, the in this case designed as a tie rod reinforcement 3 with driven and for this purpose, here connected to the pile shoe 2 by a screw connection. The latter encloses when driving the front end of the propulsion pipe 1, the ribs 4 of which engage in slots 5. The mortar outlets 13 are also locked with.

After driving in, the driving pipe 1 is pulled by hydraulic presses 8, which clamp the abutment 9 and a cross member 10 are arranged and their force on the rotating Propulsion pipe 1 transferred by between the cross member 10 .und one attached to the propulsion pipe 1 Clamping device 11 a known axial deep groove ball bearing 12 is installed. The abutment 9 can be brought to its solid base in various inclinations.

When pulled out, the ribs 4 inevitably cut helical cavities into the Soil, which is achieved in that round bars 6 are welded helically onto the driving pipe 1 and outside of the ground

Claims (1)

Correspondingly cut out and immovable guide plates 7 run. The latter get symmetrical Perforations and can thus according to FIG. 4 are then screwed to the abutment 9, when the round bars 6 appear. If obstacles are encountered while turning out or for pile areas where there is no particularly close interlocking with the ground is necessary or even unfavorable, they can be solved again. Pulling out the propulsion pipe 1 then takes place without a rotary movement and thus without generating a helical one Cavity. Those that arise when pulling out in the ground Cavities are immediately created by the remaining annular grouting channel 14 in the interior of the propulsion pipe pressed with a suitable hardening building material. The uniform covering of the reinforcement 3 with the grout is maintained by spacers 15. Claim: Method for the production of a reinforced anchor post made of in-situ concrete, which by means of a Propulsion pipe is introduced, which is closed by a pile shoe remaining in the ground and has ribs on its outer wall that create helical cavities in the ground let that are pressed with hardening building materials when pulling the jacking pipe, characterized in that the arranged on the outer wall of the propulsion pipe (1) Ribs (4) create the helical cavities only when pulling the propulsion pipe (1).
