Definitions
- the invention relates to a device to be used in special civil engineering for the production of sunken support columns such as darning columns or Concrete vibrating columns, with a driving lance, in their working position vertical material shaft runs and around the longitudinally displaceable a pipe is laid with a small clearance, and relates to a method for Manufacture of the support columns with the help of this device, which in principle from the DE-PS 971 834 is known.
- Such support pillars are in particular vibrating pillar pillars, mortar pillar pillars and Concrete vibrating columns. These pillars are used to support the load of buildings or of temporary loads, for example on railway bodies and airfields, if under the floor area is initially a non-load-bearing building ground and only in of a certain depth a stable building ground is available.
- vibrating plug columns in a columnar created by the vibrator Bottom opening in sections of robust material such as gravel, gravel or Sand installed and compacted by the vibrator and partially into the surrounding Floor areas displaced. This creates a pillar, especially on your Foot has a certain widening.
- Older devices e.g. B. the device described in DE-PS 971 834 for the production of in-situ concrete piles, work on ramming the device with a hammer head (battering ram).
- the prior art mentioned at the outset is used a pilot tube together with a core tube, the core tube using a striking head on the pre-drive pipe is fixed. Before and during the The core tube, which is always open at the bottom, is arranged so that it is is shorter at its lower end than the pre-drive pipe. During the ramming process it must be completely filled with concrete.
- a block is formed at the lower end, which is formed from a certain amount of concrete is and serves as a "advancement tip". Not only during the ramming process, during which the core tube must be closed at the top, but also when Pulling out the core tube and the pre-drive tube determines the Pre-drive tube on the core tube.
- DE-AS 1 110 092 describes a method and an apparatus for the production Reinforced in-situ concrete foundation piles by means of a pre-drive pipe, which with Help a battering bear is driven in, and one into the ground already introduced pre-drive pipe sunken pouring pipe known, the Pre-drive pipe and the pouring pipe after the concrete has been poured in again synchronously pulled out at the top.
- the device according to the invention is characterized in that the around the ram lance along most of the ones to be driven into the ground
- the ram length of the pipe is shifted longitudinally in several positions with the help a coupling device on the driving lance can be fixed, the driving lance with a Ramm high-frequency vibrator with vertical vibrating force and one has lower propulsion tip, and the material shaft at the lower end in Area of the propulsion tip has an opening and closing mechanism.
- the support column can be made by a) that Pipe in a position in which its lower end in the area of the lower end of the Ramming lance is located on the ramming lance, b) the ramming lance with the attached drives the specified pipe into the ground, c) detaches the pipe from the ram, and d) the ram lance retracts in the tube remaining in the ground and a material batch for the support column at the lower end of the ram lance.
- step d) fix the pipe to the ram lance and a little further pulls above, f) the pipe detaches from the ram lance and the ram lance on the Deposits the top of the dispensed material in the pipe and g) the pipe at the Ramming lance defines and this together with the pipe and the still in it shakes the present portion of the material batch with vertical movement component, and that after step g) steps e) to g) are repeated until the support column reaches the required height; or by using material still flowable concrete used and carried out the writing e) and then Repeat this writing on letter e) until the supporting column reaches the required height reached.
- the method according to the invention thus includes pulling out the Driving lance together with the pipe attached to it or without the pipe and a subsequent shaking by means of the ram lance with a new tube in the vertical direction, so that you can use the ram lance and the only one vertically acting vibrators move the material in different vertical positions can shake during filling.
- the shaking for material compaction is also during pulling up Driving lance possible. It takes a time on the order of, for example 1 minute. In cases where the material is in the pipe and in the top this funnel for the column is sufficient, so this can be done after Ramming can be completed in about a one-minute work step, whereby the ram lance does not have to be brought down again for compaction.
- the method according to the invention also allows the stuffing column to be for example, to perform soft layers of height more strongly there by Expansions are made. This is done by compressing the outer tube of the column part lying under the soft layer up to the upper edge pulled up the soft layer and then shaken down new material that forms a belly at this point.
- the sunken support columns are ideal even in non-load-bearing floors and are manufactured using a multi-purpose vibrator and at Remaining of the pipe inside the floor during the shaking, even after the material for producing the column has already been introduced into the ground.
- the ram lance can be moved longitudinally in relation to the pipe and can be before and / or after and / or during the longitudinal displacement the closing and opening mechanism on the material chute is open to let material into the pipe; then can be on the new Longitudinal shift position a new definition of the pipe to the ram lance be carried out by means of the coupling device and then a new shaking process by means of the vertical vibrator.
- the support columns manufactured in this way are optimal due to the vertical vibrating force compressed, or is required for a required degree of compression only a moderate vibration force.
- For ramming and compacting is sufficient a single jogger.
- the compaction is not done with the tip of the lance but with the lower end of the material enclosed in the tube, so that abrasion at the tip of the lance is considerably reduced.
- the outer surface of the resulting concrete support column is clean and sufficiently smooth to remove the negative skin friction of the surrounding Avoid layer of soil.
- the device according to the invention can be used very universally.
- the detachable coupling between the ram lance and the pipe can be produced in various ways.
- a form-fitting coupling comes into question, For example, by moving inwards at the top of the tube Projections that are in complementary recesses such as grooves or troughs on the Intervene on the outside of the ram lance.
- a frictional attack on the cylindrical lance outer surface preferred.
- this can be done by a manually operated screw spindle, however, because also the nearby vibrator is generally a hydraulically operated vibrator is preferred, an attack of investment jaws, by the top of the tube Seated hydraulic presses, for example, in the form of Hydraulic cylinder-piston units are operated.
- a building, a roadway or the like be built on non-load-bearing floor 1 by horizontal dot-dash hatching is indicated.
- set up a field of support or support columns for example darning columns from gravel, split, gravel, sand or lime or from concrete vibrating columns, which in the Ground to be poured.
- a finished support column 3 is shown, one the second one is under construction.
- a crawler track 4 with a tower 5 has been started up and installed.
- the loading device consists of one Concrete pump coming flexible line and one in the ram lance 12th extending conduit 18 for concrete and cement suspension.
- the vibrator 11 engages on the ram lance 12 via a tab 19.
- the ram lance 12 is cut within one in the drawings shown circular cylindrical tube 21, which at its upper end has a coupling device 22 for reversible fixing on the ram lance 12.
- the lance 12 slides on the inner tube surface with a sufficiently narrow gap that penetration of foreign material into the gap, in particular from the material that later to form the support column is largely avoided.
- a wiper ring (not shown) on the lance or inside the pipe be similar to an oil scraper ring in common piston-cylinder units.
- the pipe is chamfered on its lower edge and this chamfer together with the Driving tip 13 of the ram lance 12 in the position according to Fig.n 1 and 2 a common conical surface.
- Coupling device consisting of two opposing hydraulically loaded pistons 23, the coupling by pressing on the outer surface of the ram lance 12th cause.
- the presentation assumes a frictional contact, but can for example, by means of grooves on both sides, also a positive contact be provided.
- the ram lance is - as far as in the prior art -
- the pipe 21 is rammed in, that sits firmly on the ram lance 12 with the aid of the coupling device 22 and this surrounds in the area of its lower end.
- the driving depth can depend on go from the nature of the load-bearing floor 2 to its top (Fig. 1), or the ram lance 12 is a little further into the load-bearing soil 2 rammed (Fig. 2) so that the resulting support column 3 is anchored in this.
- the coupling device 22 is released and the Ram lance 12 withdrawn upwards, the tube 21 reached in the Position in the floor remains.
- the opening and Closing mechanism 14 and over the material shaft 15 in the ram 12 material 24, which is to form the support column 3 is drained down where it is the pipe 21 fills in whole or in part and settles down on or in the load-bearing floor 2 discontinues.
- Fig. 3 shows the filling of the entire pipe length at once, here can but can also be done in smaller steps.
- the material 24 shown as a coarse-grained trickle, but here all come for supporting columns suitable materials.
- the level that acts as the actual hammer level is not the propulsion tip 13, but a plane 26, which is the lower end plane of the tube 21.
- the abrasion of the driving tip 13 or the lamellae 14 is therefore limited.
- Fig. 5 illustrates another implementation in which after the first Introducing and compacting material does not add more material, but instead a precast concrete column 29 is introduced.
- the ram lance 12 from the Tube 21 pulled out and then inserted into this column 29, which on the from the first material 24 existing column base 27 is provided.
- This column base 27, which carries the precast concrete column 29, can itself be made of concrete or can be made from one of the other supporting materials such as gravel etc. consist.
