- Many dilerent typesv of concrete piles formed in situ are known.
- Some methods include the formation of a toot of special form on the pile.
- One known method comprises placing concrete in 'a boring tube or inside a lining inside such a boring tubeV and then using an inner ram or inner tube With'an internal monkey or with an interal ram of valve, the tube is sunk to the required depth for the formation of the foot.
- a further known method comprises forming the foot or bulb with an internal ram. If a bulb is formed a point is not necessary but an inner tube with 'a valve is used. The tube is driven by 4a monkey.
- the boring tube with the help of gripping jaws or a gripping device could be sealed in relation to the cement or concrete lling at various positions as required. In this manner it is possible irst to drive the tube downwards and then to move the tube upwards slightly and to form a bulb-like foot.
- the gripping jaws or'gripping device inthe form of a head are connected with a base plate having a ram and a sealing face movable in such a manner that by moving the face, of the suspension device (14 in the accompanying drawings) towards the face of the ram a clamping action is obtained in the tube.
- One object of the present invention is to ensure that this loosening of the concrete plug occurs in each case and, possibly, obstacles beneath the core of concrete'are pressed out of the way.

Many dilerent typesv of concrete piles formed in situ are known. There are also many known ways of producing such piles. Some methods include the formation of a toot of special form on the pile. One known method comprises placing concrete in 'a boring tube or inside a lining inside such a boring tubeV and then using an inner ram or inner tube With'an internal monkey or with an interal ram of valve, the tube is sunk to the required depth for the formation of the foot. A further known method comprises forming the foot or bulb with an internal ram. If a bulb is formed a point is not necessary but an inner tube with 'a valve is used. The tube is driven by 4a monkey.
In' order to remove some of the diiculties with processes and devices known up to now t-he inventor already suggested in an earlier invention that the boring tube with the help of gripping jaws or a gripping device could be sealed in relation to the cement or concrete lling at various positions as required. In this manner it is possible irst to drive the tube downwards and then to move the tube upwards slightly and to form a bulb-like foot. In an apparatus for carrying out this method the gripping jaws or'gripping device inthe form of a head are connected with a base plate having a ram and a sealing face movable in such a manner that by moving the face, of the suspension device (14 in the accompanying drawings) towards the face of the ram a clamping action is obtained in the tube.
In this older devicc'it was noted that the plug of concrete was detached from the tube owing to its weight and owing -to the percussive elfect to which the tube was exposed.
-One object of the present invention is to ensure that this loosening of the concrete plug occurs in each case and, possibly, obstacles beneath the core of concrete'are pressed out of the way.
An illustrative embodiment of the invention is now described with reference to the attached drawings.
FIGURES l to 8 are vertical sections illustrating the formation of a pile.
FIGURE 9 is a 'longitudinal section of the device denoted by general reference 6 in the previous drawings.
FIGURE l0 is a section on the line X-X of FIG- URE 9.
In FIGURE l, 1 denotes the boring tube lying above the ground surface 5. 4 denotes concrete in the tube 1, and 3 denotes a iilling funnel for putting in the concrete. The figure is a vertical section.
FIGURE 2 shows the tube in the same position, i section, with the concrete 4 in it. 8 denotes the lower part of ya monkey (the rest of the monkey is not shown), while 9 denotesthe associated ramming cap. 1i) and 11 denote flexible hydraulic leads passing through the cap 9 to the downwardly acting cylindrical jack or pressure device 2 which contains within it a piston 14 (shown in FIG. 9). The jack 2 is placed below a locking or grip- 3,1492 Patented May 25, 1965 ICC ping device 6 suspended by a rope 7. This gripping device is described in more detail below with reference to FIG- URES 9 and l0.
FIGURE 3 shows the jack Z. It also `shows in section the tube 1 which has already been rammed into the ground with the concrete filling 4 in it. The tube 1 is sunk to the necessary depth by means of the monkey 8.
FIGURE 4 is a section of the device shown in FIG- URE 3 with the cap 9 and the monkey 8 removed. The ram 13 has been hydraulically driven and owing to the actuation of the gripping device 6 the tube has been raised somewhat. Consequently the concrete below the tube 1 has spread out.
FIGURE 5 is a `section and elevation of the same parts as shown in FIGURE 4 together with the parts 8 and 9. It is to be seen that the. tube 1 with the gripping device 6 in the active position has been driven further into the ground after which the gripping device 6 is released and the piston 14 (FIG. 9) is driven back in the jack 2 hydraulically.
As shown in FIGURE 5, the whole tube 1 with the stationary device consisting of the elements 2, 6, and 13 is d-riven down in the direction of the arrow with the help of the monkey 8 so that the tube is driven further into the earth. The foot 12 is then expanded as shown and the structure takes on the vform as shown in FIGURE 6. As shown in this ligure the reinforcement 24 is in place while the funnel 3 is in position for charging in concrete. Before the reinforcement 24 is put in place it is, of course, necessary to remove the cap 9, to release the element-s 2, 6, and 13 hydraulically and remove it by means of the rope 7.
FIGURE 7 shows the structure as shown in FIGURE 6 after removal of the funnel 3. The hydraulic device consisting of 2, 6, and 13 has been .placed in position for consolidating the concrete and for moving the tube 1 in steps upwards with the gripping device 6 in the active position. The final result is shown in FIGURE 8.
By additional blows onthe concrete column or pile above the foot 12 it is possible to use the foot 13 to form further bulges in the concrete column of any desired vertical dimension at any required height.
FIGURE 9 shows a section of part of the device denoted by the general reference 6 in the previous ligures. Reference numeral 2 again denotes the downwardly acting jack and 13 denotes the ram of the piston 14 in this jack. 15 denotes an oil supply pipe and 16 an oil return pipe. The direc-tion of flow in these pipes can be reversed to allow the jack to act in both directions. The pipe. 15 is connected with the oil pipe 10 Iand the pipe 16 with the oil pipe 11. The pipes 11 and 10 open into the jack at the positions 26 and 25 respectively. The suspension cable or rope 7 is secured to an eye 27 in the part 21.
FIGURE l0 is a section on the line X-X of FIG- URE 9 and shows that the part 17 is tapered (see FIG.- URE 9) so that during lowering of the cylinder 21 and simultaneous raising of `the piston 2li by passing pressure oil through pipe 16 into cylinder 21, the wedge 17 connected at its upper end to the piston 2 will be raised while the parts 18 connected by the links 22 at 23 to the cylinder 21 will be simultaneously lowered to press outwards the parts 18 so that the whole device is held fast inthe tube 1.
This eiiect is heightened since simultaneously the piston 14 presses the ram 13 against the part 2 an-d' Y' s f against the` wedge 17, pressing the latter upwards so that the parts 18 and the rubber parts 19 are pressed against the wall ofthe tube. The rubber parts 19 attached in any well known manner to parts 13` serve to prevent the entry of dirt particles to theA gap and also during release ofthe gripping device to press the parts i8 away from the tube l.
The pressing away eifectwith the help of the part i3 is accomplished in such a manner, as shown in FIGUREv 9 that the part 13 is supported in relation to the concrete layer 4.
