Description

The present invention relates to a vibrator arrangement for producing filling material columns.

Vibrator arrangements for the production of material or filling material columns in the ground are generally known. The columns of material consist for example of sand or gravel whose grain size can be matched to the place of use. Such vibrator arrangements comprise at least one silo or material tube with a Füllmaterialauslass at one end and a vibrator arranged on the silo tube. In Rüttleranordnungen, which are designed as deep shaker, the vibrator is disposed at a lower end of the silo tube and is located during operation in the ground in Aufsatzrüttlern the vibrator on top of the material tube, arranged.

Known Rüttleranordnungen have a filler container, which is arranged in the upper region of the silo tube and which serves to supply the silo tube filling material. Here, the filler tank must be filled at some height above the ground with a suitable construction machine, which can be a considerable effort.

In the WO 90/15904 For example, there is proposed a method for producing filling material columns, in which the filling of a silo tube with filling material takes place at ground level. For this purpose, openings are provided in the silo tube, through which the filling material is to flow into the silo tube. The openings are not closable, allowing soil to penetrate into the silo tube when the silo tube is inside the cavity.

EP 0 861 944 A1 shows a vibrator arrangement according to the preamble of claim 1.

It is an object of the present invention to provide a vibrator arrangement which does not have the above-mentioned disadvantages.

This object is achieved by vibrator arrangements according to claims 1 and 12. Embodiments and developments are the subject of dependent claims.

The vibrator assembly according to the invention, according to one embodiment, comprises: at least one elongated silo tube for receiving fill material having a longitudinal direction, a filler outlet at a longitudinal end of the silo tube, and a jacket; at least one vibrator, which is arranged on the silo tube; and at least two outer seals arranged on the jacket of the silo tube and spaced along the longitudinal direction of the silo tube.

The vibrator arrangement may comprise a plurality of silo tubes juxtaposed transversely to the longitudinal direction.

Furthermore, the vibrator arrangement can have at least one inner closure in the interior of the silo tube, which is arranged in the longitudinal direction between two outer closures. In the silo tube, a further inner closure can be arranged between two further outer closures. It can be arranged as many inner closures inside the silo tube and any number of outer closures on the jacket of the silo tube.

The vibrator of Rüttleranordnung can be designed as Tiefenrüttler or Aufsatzrüttler.

The vibrator arrangement can have a filler material container which can be moved in front of the outer closures. The filling material container can be movably arranged along at least one guide rail arranged on the silo tube. The filler container can be guided for example by means of rollers on the guide rail. For this purpose, guide rails can be arranged on the silo tube.

The vibrator assembly according to the invention comprises according to a further embodiment: at least one elongate silo tube for receiving filling material having a longitudinal direction, a Füllmaterialauslass at a longitudinal end of the Silorohrs and a jacket; at least one vibrator, which is arranged on the silo tube; at least one outer closure arranged on the jacket of the silo tube; and at least one filling material container arranged to be movable along the longitudinal axis of the silo tube in front of the outer closures, the filling material container having at least one opening facing the jacket of the silo tube.

Embodiments of the present invention offer the particular advantage that the filling of the silo tubes with filler material does not have to take place at its upper end at a considerable height from the ground. The movable filling container for providing the filling material can for example be arranged lying stationary on the ground on the ground and filled there. The silo tube can then be moved past the stationary filling container and filled with filling material via the outer closures. The space required upwards is significantly reduced compared to conventional Rüttleranordnungen. This can be advantageous or even necessary in some locations. Such locations are, for example, entry lanes at airports, places that can only be operated at low altitude for safety reasons. In addition, the vibrator assembly is mechanically relieved considerably when the filler container is placed resting on the ground, since the Rüttleranordnung itself no longer has to carry the filling container.

Vibrator arrangements with a vibrator and a silo tube are used to consolidate or consolidate soil (soil improvement). By means of the vibrator, they generate vibrations that compress the soil and in this way penetrate into the soil. This creates an approximately cylindrical and elongated cavity in the ground. To produce a filling column, filling material can be introduced into the cavity via the silo tube, which can be, for example, gravel or sand. Then the vibrator arrangement moved back down to compress the filling material, so that the filling material is pressed both in the direction of the cavity bottom and in the direction of the cavity walls. Subsequently, the Rüttleranordnung is moved up and again spent filler in the cavity and compacted using the Rüttleranordnung 1. This is repeated until the cavity is filled completely or at least up to a desired height (according to the respective requirements) with filling material and finally a filling material column has developed in the soil. As a rule, a large number of such filling material columns are produced over a defined area in order to achieve soil improvement on this surface. By such methods, for example, an increased load-bearing capacity of the soil, a reduction in the tendency to soil liquefaction and a reduction in soil settlement after development is achieved.

In FIG. 1 An embodiment of a vibrator arrangement 1 for carrying out such a method is shown. The vibrator arrangement 1 has a longitudinally extending tube 111 in the longitudinal direction 111, which can be filled with gravel or sand or another suitable filling material. At a lower end of the vibrator assembly 1, the silo tube 110 has a filler outlet 120. The vibrator arrangement 1 also has a vibrator 130. In the in FIG. 1 In the embodiment shown, the vibrator 130 is designed as a deep vibrator and arranged in the longitudinal direction next to the Füllmaterialauslass 120 at the bottom, the soil or the bottom end facing the Rüttleranordnung 1. During operation, the vibrator 130 generates vibrations that cause the vibrator assembly to penetrate the soil. Deep vibrator, like the one in FIG. 1 Deep vibrators shown 130, are basically known, so that it can be dispensed with further comments on this. It should be noted that the use of a deep vibrator is merely an example. Of course, any other vibrators, such as Aufsatzrüttler (not shown) may be used, which are then to be arranged at the top, the bottom or the soil away from the end of the Silorohrs 110 and the Rüttleranordnung 1.

The silo tube 110 may have any cross-section in a sectional plane perpendicular to the longitudinal direction 111, such as an elliptical, in particular circular, a rectangular, or any polygonal cross-section. As a shell, the outer shell or the shell or envelope surface of the silo tube is referred to below. The length of the silo tube 110 is for example in the range between 5m and 20m, the cross-sectional area of the silo tube 110 is for example in the range between 0.03m ² and 0.25m ² , wherein in a circular or elliptical silo tube the diameter or the length of the main axis between 0.2m and 0.5m.

The vibrator arrangement 1 has at least one outer closure 150a, 150b on the jacket of the silo tube 110. In the in FIG. 1 shown embodiment, two outer closures 150a, 150b in the longitudinal direction 111 spaced from each other. It is also possible to provide more than two outer closures or only one outer closure. The at least one outer closure 150a, 150b is designed such that it can open and close a corresponding opening on the silo tube 110. In particular, the outer closure 150a, 150b may be designed such that it seals the interior of the silo tube 110 airtight from the external environment.

The vibrator arrangement 1 can furthermore have at least one inner closure 160, which is arranged in the interior of the silo tube 110. This inner closure 160 is configured so that it can divide the silo tube 110 in the interior so that filling material in the silo tube selectively passes or can not pass through the inner closure 160. The inner closure 160 may also be configured to airtightly separate the two portions of the silo tube between which it is disposed. In particular, the inner closure 160 is designed so that it is arranged completely inside the silo tube, so that parts of the inner closure 160 do not protrude beyond the jacket 110, neither in the open nor in the closed state of the closure 160, and so that the inner closure 160 prevents the penetration of the silo tube 110 does not obstruct the floor.

According to one exemplary embodiment, the vibrator arrangement has only one outer closure, for example the outer closure 150a according to FIG FIG. 1 and an inner closure 160. The inner closure 160 is in this case arranged in the longitudinal direction below the outer closure 150a and forms a lock with the outer closure 150a. This outer closure is arranged spaced in the illustrated example to an upper end of the silo tube. This is just an example. As another example, the one outer closure is disposed adjacent to the upper end in the shell 110. According to another example, the one outer closure is arranged on the front side at the upper end of the silo tube. Of course, even with several outer closures, it is possible to arrange one of the closures on the jacket of the silo tube 110 directly at the upper end or even to arrange it on the front side at the upper end.

For filling the silo tube 110 with filling material, a filling material container 200 can be provided, which can be moved longitudinally along the silo tube 110. FIG. 2 FIG. 2 shows a horizontal cross section, that is to say a cross section in a sectional plane perpendicular to the longitudinal direction of the silo tube 110, through the filling material container 200 and through the silo tube 110.

At the silo tube 110, two guide rails 251, 252 can be arranged on the respective opposite shell sides. At these guide rails 251, 252, the filler container 200 can be arranged to be movable along the longitudinal direction 111 in front of the at least one outer closure 150a, 150b. Instead of two guide rails 251, 252, alternatively, only one guide rail or more than two guide rails can be provided (in FIG. 2 not shown). The filling material container 200 has at least one opening 260 which faces the jacket, in particular the at least one outer closure of the silo tube. This opening 260 may correspond to the outer closures 150a, 150b, but it may also be smaller or larger than the outer closures. Rollers 210, 220, 230, 240, 250 may be provided for guiding the filling container 200 movably arranged on the vibrator arrangement 1. It can, as in FIG. 2 shown, two roles each 210, 220 and 230, 240 frictionally engage a guide rail 252 or 251, so that only one degree of freedom along the longitudinal direction 111 of the vibrator arrangement 1 remains for the movability of the filling container 200. It is also possible, moreover, to arrange more than one filling container 200, for example two filling material containers, spaced from each other along the longitudinal direction on the vibrating arrangement. The filler container can be detected at any position of the silo tube, such as in front of one of the outer seals, to replenish material over the respective outer closure each time that outer closure is opened.

It should be noted that the provision of a movable on the silo tube 110 filling container, as in FIG. 2 is illustrated, but not limited, to a silo tube, such as the silo tube 110 of FIG FIG. 1 , with at least two longitudinally spaced outer closures, such as outer closures 150a, 150b according to FIG FIG. 1 to be provided. Such a movable filling container can be provided on any silo tube of a vibrator arrangement, such as on a silo tube, which has only one feed opening on the jacket of the silo tube or on an upper front end. Depending on whether the feed opening is located at a position that penetrates into the ground during operation of the vibrator, the feed opening is by an outer closure - comparable to one of the closures 150a, 150b according to FIG. 1 - lockable or not. In the interior of the silo tube, a lock for filling material may be provided, wherein the one feed opening above the lock is arranged on the silo tube.

According to a further exemplary embodiment (not shown), filling of the silo tube via one of the outer closures takes place via a feed line or a feed tube, which is designed to convey filling material. An end of this delivery hose facing the silo tube 110, which is also referred to below as an outlet end, is fastened, for example, to a carriage which can be moved along the silo tube. Thereby, the outlet end can be reciprocated between different external connections, if there are several external closures, and the outlet end can be attached to the silo tube be held above the ground when the silo tube moves into the ground. At an end opposite the outlet end of the feed tube, a material conveyor, such as a pump, may be arranged to supply material to the feed tube.

In the FIGS. 1 and 2 essential components of embodiments of a vibrator arrangement 1 according to the invention are shown. It will be described below in the FIGS. 1 and 2 embodiments shown possible functional principles of the vibrator shown illustrated.

At the in FIG. 1 illustrated embodiments, two outer closures 150a, 150b are arranged on the jacket of the silo tube 110, namely a first outer closure 150a and a spaced in the direction of the lower end to the first outer closure 150a second outer closure 150b. A distance between these two outer closures 150a, 150b is for example between 1 m and 5m. Inside the silo tube 110, an inner closure 160 is provided between the two outer closures 150a, 150b. In addition, a further inner closure (not shown) may be provided, which is arranged in the direction of the lower end of the silo tube 110 below the second outer closure 150b. An inner closure 160 divides the silo tube into two chambers, a plurality of inner closures divide the Silorohrs into a plurality of chambers. The outer closures 150a, 150b may produce air-tight or pressure-tight seals. In the silo tube 110, an overpressure atmosphere can therefore be built up during operation relative to the environment, in particular the environment in the generated cavity. This may be necessary, especially in larger cavity depths, in order to avoid the penetration of water or liquefied soil into the silo tube, since this, for example, could impair the flowability of the filling material. In each case, these outer closures 150a, 150b are realized so "airtight" that when the closure 150a, 150b or 160 is closed, the overpressure existing in the silo tube 110 can not escape via the respective closure.

Accordingly, the at least one inner closure 160 can produce an airtight or pressure-tight closure. This prevents that an overpressure in a chamber with closed inner closure 160 can escape into an adjacent and separated by the inner closure of the other chamber another chamber.

If a filling material column is now to be produced in the soil, a cavity in the soil is formed by shaking, for example, when the inner closure 160 is initially closed. The filler container 200 may for example be arranged stationary resting on the ground and be filled continuously with filling material. In addition, it is also possible to arrange the filling material container 200 movable on the silo tube 110. When the vibrator assembly 1 makes shaking motions, it penetrates into the ground and moves downwardly relative to the filling material container 200 along the longitudinal direction 111 into the ground. When one of the outer closures 150, such as, for example, the second outer closure 150b first reaches the opening 260 of the filler container 200, the corresponding outer closure 150b can be opened. The filling material container 200 and its opening 260 are designed so that filling material can be introduced into the silo tube 110 through the opening 260 via the opened outer closure 150b.

As the vibrator assembly progresses further into the soil, the second outer closure 150a also reaches the opening 260 of the filler tank. When the inner closure 160 is closed, the upper silo tube region 170a can be filled with filling material. When this filling operation is completed, the outer closure 150a (airtight) is closed. Thereupon, an overpressure may be created in the lower region 170b to prevent the penetration of groundwater or moisture into the silo tube. In this case, a lock-type effect is achieved with the inner closure 160, in such a way that overpressure only in the region 170b but not over the entire Silorohr 170a, 170b must be generated away, which, for example, requires less powerful compressors.

Once the vibrator assembly 1 has created a cavity of a desired depth, it is moved upwardly out of the cavity, thereby introducing the filler material in the region 170b into the cavity, since the filler outlet 120 is no longer blocked by soil. Due to the overpressure atmosphere prevailing in the region 170b and the filler outlet 120, little or no water or liquefied soil can penetrate into the filler outlet and the region 170b of the silo tube. If a desired amount of filler material spent in the cavity, the vibrator assembly is again guided into the cavity to solidify the already located in the cavity filler, which is pressed on the one hand in the direction of the cavity bottom and in the direction of the cavity walls. Subsequently, the vibrator assembly is again moved upward, thereby repeatedly filling material is placed over the Füllmaterialauslass 120 in the cavity. The newly introduced filling material is then compacted or solidified again. In this connection, it should be noted that the silo tube is pointing downwards, i. may be open in the direction of the Füllmaterialauslasses, so that each time when the Rüttleranordnung moves upward "automatically" filler from the silo tube 110 flows into a formed below the silo tube cavity.

If no water or liquefied soil can penetrate more into the silo tube, for example if the filling height of the filling material column is already above the groundwater level, an overpressure atmosphere within the silo tube 110 is no longer necessary. The inner closure 160 can be opened because its lock effect is no longer needed. After opening the inner closure 160, the filling material located in the region 170a can penetrate into the region 170b and further into the cavity, wherein this filling material is first introduced into the cavity in a certain amount and then compacted.

This is followed by another filling material entry into the cavity. This is repeated until a defined height of the filling material column is reached, it being possible to feed filling material to the silo tube whenever the outer closures 150a, 150b open the opening 260 of the filling material container 200 happen. By using the lock formed by the inner shutter 160, the filling material input can be regulated because the capacity of a silo tube portion 170a, 170b is known in advance. The absorption capacity is, for example, 1 m ³ in the region 170 a. From a certain level, only the lower outer closure 150b can be used.

If the filling material column reaches a height at which the outer closure 150b can no longer reach the opening 260 of the stationary filling material container 200 at the bottom, the filling material container can be fastened to the silo tube 110 such that the opening 260 and the outer closure 150b are always opposite one another , The filling material container 200 is then moved upwards together with the silo tube 110 until the filling material column has reached the desired filling height. For this purpose, the filling material container 200 must be filled in a suitable manner above the soil level (for example with a suitable construction machine or a suitable conveying device).

Alternatively, the cavity may first be produced without filling material being supplied to the silo tube 110. When the cavity reaches the desired depth, the vibrator assembly is moved upwardly. In this case, the outer and inner closures 150a, 150b, 160 can be actuated so that the filling material can be brought into the cavity as described above.

In the FIG. 3 shown jogger assembly 1 has two elongated in a longitudinal direction 111 Silorohre 110a, 110b, which are arranged transversely to the longitudinal direction 111 side by side. It should be mentioned at this point that in principle any number of silo tubes can be arranged in a vibrator arrangement. The two silo tubes 110a, 110b can be filled with filling material. At a lower end of the vibrator arrangement, each silo tube 110a, 110b has a Füllmaterialauslass 120a, 120b, wherein in two Silorohren 110a, 110b, a common Füllmaterialauslass 120 can be provided. At the in FIG. 3 shown embodiment, a vibrator 130 is disposed between the two Füllmaterialauslässen 120a, 120b. This vibrator is a deep vibrator, which is at the bottom of the vibrator, so the bottom side, attached. Of the Vibrator 130 also generates vibrations in this embodiment which allow the vibrator arrangement 1 to penetrate into the soil or the soil.

In the FIG. 3 shown jogger assembly 1 may be designed so that at least one or each of the outer closures 150a, 150b, 150c two Silo tubes 110a, 110b is common, so that a closure simultaneously opens or closes corresponding openings on the sheaths of the two Silorohre 110a, 110b. Such an outer closure can therefore extend transversely to the longitudinal direction 111 over both silo tubes 110a, 110b.

The vibrator arrangement 1 according to FIG. 3 also has at least one or more inner seals 160, which are arranged in the interior of the silo tube 110a, 110b. These inner closures 160 may be such that they completely or partially close the corresponding silo tube 110a, 110b inside, so that filling material located in the silo tube 110a, 110b can not penetrate the inner closure 160. The inner closures 160 can also be designed here to produce an airtight seal inside the respective silo tube 110a, 110b. According to the in FIG. 3 shown embodiment, at least one such inner closure 160 between two outer closures 150a, 150b is arranged. In FIG. 2 In addition, it is shown that a further inner closure 160 can be arranged between two further outer closures 150b, 150c. Two inner closures 160 spaced apart in the longitudinal direction 111 may form an air and / or filling material lock, if they are activated accordingly.

In FIG. 4 is a side view of a sectional view of an embodiment with a silo tube 110, an outer closure 150 and 200 shown with Füllmaterialbehälter. The filler container 200 may be formed so that the filler easily flows to the opening 260. The opening 260 may be designed to be closable. The filler tank 200 may be further provided with another opening (not shown) for supplying the filler material. It is also possible to provide a suitable conveying device for feeding the filling material instead of the filling material container 200.

In FIG. 5A 2 shows, for example, how two of the inner closures 160a, 160b can be arranged in two silo tubes 110a, 110b arranged side by side transversely to the longitudinal direction 111. These inner closures 160a, 160b each have a movable closure plate 161 which can be moved via a drive unit 163 into a receptacle 163 so that the filling material in the corresponding silo tube 110a, 110b can pass through the inner closure 160a, 160b. The inner closures 160a, 160b can be designed such that the silo tubes are each hermetically sealed there, so that overpressure atmospheres can be produced in the silo tube regions 170a, 170b. The closure plates 161 are arranged in the illustrated example obliquely with respect to the longitudinal direction of the silo tubes 110a, 110b and obliquely movable relative to this longitudinal direction. An angle between the plates 161 and the longitudinal direction is for example between 45 ° and 60 °.

In the FIG. 5A shown drive unit 163 can be controlled manually or automatically. The drive unit 163 may be designed, in particular, as a pneumatic drive, an electric drive, or any other suitable drive. In FIG. 5B is a cross section 113 through the two juxtaposed silo tubes 110a, 110b of the embodiment shown. The silo tubes 110a, 110b have flat surfaces on the mutually facing surfaces, so that the silo tubes 110a, 110b can be arranged side by side as far as possible without joints and gaps. At the sides facing away from the other silo tube sides, the silo tubes 110a, 110b may be rounded. Two silo tubes 110a, 110b can also be formed starting from a correspondingly shaped silo tube into which a dividing wall is inserted.

At the in FIG. 5A In the embodiment shown, the inner closures are arranged so that the drive - in the example a hydraulic cylinder - of an inner closure 160a, 160b in a silo ear 110a, 110b projects into the respective other silo tube 110b, 110a. This allows a particularly space-saving realization of the inner closures.

Is only a silo tube present, as in the embodiment according to FIG. 1 Thus, the inner closure 160 can be realized like an inner closure of one of the silo tubes, with the difference that the inner closure 160 of a single tube does not protrude beyond the single silo tube 110.

In FIG. 6 For example, in a side view, an outer closure 150 is shown by way of example, which is arranged on the jacket of a silo tube 110 and which can be used in the previously described vibrator arrangements. In the exemplary embodiment shown, the closure 150 has a closure plate 151 and a drive unit 152. The closure 150 may be designed to make the interior of the silo tube 110 airtight from the environment. In addition, any other closures are conceivable, which are suitable to complete the interior of the silo tube 110 airtight from the environment. The outer closure can be opened and closed as required by means of a control unit (not shown), which drives the drive unit 152. An opening of the outer closure takes place in a previously explained manner, for example, in each case when filling material is to be supplied. The drive unit 151 is, for example, an electric drive unit and / or a hydraulic drive unit.

In the embodiment according to FIG. 6 Closure plate 151 is slidably mounted such that the closure plate 151 can be moved by the drive unit 152 parallel to the jacket of the silo tube to release or close an opening 153 in the jacket of the silo tube.

In a further embodiment, the in FIG. 7 is shown, the closure plate 151 is rotatably or hingedly mounted relative to the jacket of the silo tube. The closure plate 151 is - as in the example according to Figure 6- larger than the opening 153 to completely close the opening 153 can. The drive unit 152 is configured to fold the closure plate 151 inwardly away from the opening 153 to expose the material supply opening, or to force the closure plate 151 against the jacket of the silo tube 110 to close the opening 153.

In a further embodiment, the drive unit 152 is according to FIG. 7 adapted to press the closure plate 151 only against the jacket of the silo tube 110, and to release the opening 153, when a force is exerted externally on the closure plate 151, which presses the closure plate 151 inward. Control of the closure plate via the drive unit 152 may be dispensed with in this case. An opening occurs whenever a force is exerted externally on the closure plate 151, which opens the closure plate 151, wherein the drive unit 152 again presses the closure plate 151 against the mantle to close the opening 153 and the closure 150, if the external force is eliminated. For this purpose, the drive unit comprises, for example, a spring mechanism, which is realized in such a way that the closure plate 151 is opened against a spring force, or a hydraulic mechanism with a bladder accumulator, which is realized in such a way that the closure plate 151 is opened against a hydraulic force.

The external force to open can be done, for example, by the feed tank 200. For example, the supply container may have a nose which presses against the closure plate to open it when the container is in front of the opening 153.

An inner closure 160, related to FIG. 1 has been explained and which is disposed completely within the silo tube 110, and inner closures 160a, 160b, in connection with FIG. 5A are fully assembled within a tube assembly having two or more silo tubes, are not limited to be used in connection with outer seals. Thus, the arrangements described above can be modified, for example, so that it is dispensed with the outer closures and that instead of a material supply from above, ie via an upper end face of the silo tube. In order to meet height restrictions, material supply can take place, for example, via a supply line, so that it is possible to dispense with a voluminous material container above the silo tube 110. Inside a silo tube, two or more inner closures may be provided, with two adjacent ones forming a lock.

Finally, it should be understood that elements and components previously discussed in connection with a particular embodiment may be combined with elements and components of other embodiments, even if not explicitly mentioned in the foregoing text, and without departing from the spirit of the invention.
