Description

Die Erfindung betrifft eine Vorrichtung zum zentrischen Einbringen einer Verbaustütze in ein Erdbohrloch.The invention relates to a device for the central insertion of a sheeting support into an earth borehole.

Bekanntlich werden beim Trägerbohlenverbau, der auch als "Berliner Verbau" bezeichnet wird, die Träger oder Verbaustützen der Trägerbohlwände in vorher angefertigte Bohrlöcher eingesetzt. Diese Erdbohrlöcher können eine Tiefe von 10m haben.As is known, in the beam screed shoring, which is also referred to as the "Berlin shoring", the beams or shoring supports of the screed walls are inserted into previously drilled holes. These boreholes can be 10m deep.

Trägerbohlwandverbaue waren bisher im Wesentlichen dadurch gekennzeichnet, daß die Trägerbohlwände selbst an Ort und Stelle zugeschnitten werden mußten, weil es in der Regel äußerst schwierig ist, die Stützenabstände so genau anzuordnen, daß auch vorgefertigte Verbauwände verwendet werden konnten. So war man bisher im wesentlichen auf Holz als Baustoff für die Verbauwände angewiesen, was wiederum eine entsprechende Vielzahl an Stützen erforderte, die den Verbau sehr teuer machten. Es wurden zwar Versuche unternommen, z.B. Stahlbetonplatten in Stützen mit U-förmigem Querschnitt einzusetzen, doch haben sich diese Verbauarten nicht durchsetzen können, weil sie immer noch ein Verkeilen der Verbauwände an den Stützen und entsprechend große Abstandtoleranzen bzw. angemessen große Flanschen der Verbaustützen erforderten. Damit waren auch diese Verbauarten noch zu lohnintensiv und, da das Verkeilen von Hand erfolgen mußte, nicht sicher genug, denn das Personal mußte in der ungeschützen Bauqrube arbeiten.Beam screed walls were previously mainly characterized by the fact that the screed walls themselves had to be cut to size on site because it is usually extremely difficult to arrange the column spacing so precisely that prefabricated shoring walls could also be used. So far, one was essentially dependent on wood as a building material for the shoring walls, which in turn required a corresponding number of supports, which made the shoring very expensive. Attempts have been made, e.g. Reinforced concrete slabs can be used in U-shaped cross-sections, but these types of shoring could not prevail because they still required wedging of the shoring walls on the supports and correspondingly large spacing tolerances or appropriately large flanges of the shoring. This meant that these types of installation were still too cost-intensive and, since wedging had to be done by hand, was not safe enough because the personnel had to work in the unprotected construction pit.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Möglichkeit zu schaffen, an sich aus dem Kanalverbau bekannte Verbauelemente, nämlich Verbaustützen mit im Wesentlichen formschlüssigen Führungen für darin qeführte Verbauplattennicht nur im Kanalverbau, sondern auch in großen Baugruben als einseitige Abstützung, insbesondere auch als wiederverwendbare Abstützung einsetzen zu können.The present invention has for its object to provide a possibility, known from the channel shoring shoring elements, namely shoring supports with essentially form-fitting guides for shoring panels guided therein not only in the channel shoring, but also in large construction pits as a one-sided support, in particular also as a reusable support to be able to use.

Dies erfordert aber ein genaues Einsetzen der Stützen in die Erdbohrlöcher und ein genaues lotrechtes Aufstellen. Die Bohrtechnik ist inzwischen soweit ausgereift, daß man davon ausgehen kann, daß die Bohrlochabstände eine ausreichende Genauigkeit haben. Es kommt somit darauf an, auch die Verbaustützen auf genauen Abstand, d.h. zentrisch in die relativ großen Erdbohrlöcher einzusetzen.However, this requires an exact insertion of the supports into the boreholes and an exact vertical installation. The drilling technology has now matured to such an extent that it can be assumed that the borehole spacing has sufficient accuracy. It is therefore important that the shoring supports are at a precise distance, i.e. centered in the relatively large boreholes.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung zum zentrischen Einbringen einer Verbaustütze in ein Erdbohrloch gelöst, deren Merkmale im Anspruch 1 angegeben sind.This object is achieved according to the invention by a device for the central introduction of a shoring support into an earth borehole, the features of which are specified in claim 1.

Diese Vorrichtung wird am unteren Ende einer -Verbaustütze angeklemmt und zusammen mit dieser in das Erdbohrloch herabgelassen. Sobald die Stütze auf der Sohle des Bohrloches aufsitzt, werden die Zentrierkolben der Vorrichtung ausgefahren, die sich am Umfang des Erdbohrloches abstützen und das untere Ende der Verbaustütze zentrieren. Mittels geeigneter Ausrichteinrichtunqen, z. B. Lasergeräten, wird die Verbaustütze lotrecht fixiert und dann z.B. in eine auf der Bohrlochsolhle eingebrachte Mörtelmasse, Fundamentbeton oder dgl. eingesetzt. Ein späteres Ziehen der Stützen kann durch geeignete Maßnahmen sichergestellt sein, z.B. Abtrennen des Stützenfußesoder dgl., was hier nicht Gegenstand der Erfindung ist.This device is clamped to the lower end of a shoring support and lowered together with it into the earth borehole. As soon as the support sits on the bottom of the borehole, the centering pistons of the device are extended, which are supported on the circumference of the borehole and center the lower end of the shoring. By means of suitable alignment devices, e.g. B. laser devices, the shoring support is fixed vertically and then e.g. in a mortar, foundation concrete or the like placed on the borehole. A later pulling of the supports can be ensured by suitable measures, e.g. Severing the column base or the like, which is not the subject of the invention here.

Die erfindungsgemäße Vorrichtung bietet den Vorteil, daß es nun möglich ist, Stützen im Trägerbohlenverbau zu verwenden, in die vorgefertigte Verbauplatten formschlüssig einsetzbar sind, d.h. bei denen die Verbauplatten sowohl senkrecht zu ihrer Fläche als auch in Richtung ihrer Längserstreckung fixiert sind. Damit erübrigt sich das lohn-, arbeits- und gefahrenintensive Verkeilen der Verbauplatten in der ungeschützten Baugrube. Ferner ist es möglich, mit größeren Stützenabständen, und damit mit weniger Verbaustützen und Erdlochbohrungen zu arbeiten, womit eine weitere Wirtschaftlichkeit einerseits und ein schnellerer Verbau sichergestellt ist.Ferner kann das Verbaumaterial bei geringem Personalaufwand auch mehrfach benutzt werden, wogegen es bisher häufiq der Fall war, daß das Verbaumaterial im Erdreich verblieb.The device according to the invention has the advantage that it is now possible to use supports in the screed shoring in which prefabricated shoring panels can be inserted in a form-fitting manner, ie in which the shoring panels are fixed both perpendicular to their surface and in the direction of their longitudinal extent. This eliminates the wage, labor and risk of wedging the shoring panels in the unprotected excavation pit. It is also possible to work with larger column spacings, and thus with fewer shoring columns and bores in the ground, which on the one hand ensures further economy and faster installation. Furthermore, the shoring material can also be used several times with low personnel expenditure, whereas it has been common up to now the case was that the lining material remained in the ground.

Der Innendurchmesser des Traggehäuses 1 ist jedoch größer als der Querschnitt einer in ein Erdbohrloch einzubringenden Verbaustütze 2. In dem Traggehäuse 1 ist ein ringförmiger Einsatzboden 3 an geordnet, dessen Innendurchmesser ebenfalls größer ist, als der Querschnitt einer Verbaustütze 2.The device according to the invention consists of an annular support housing 1, the outer diameter of which is slightly smaller than the diameter of an earth borehole at the construction site. However, the inner diameter of the support housing 1 is larger than the cross section of a shoring support 2 to be inserted into an earth borehole. In the support housing 1 there is an annular insert base 3, the inside diameter of which is also larger than the cross section of a shoring support 2.

Auf dem Einsatzboden 3 sitzen eine Anzahl, vorzugsweise eine ungerade Anzahl radial gerichteter druckmittelbetätigter Hubzylinder 4 mit radial nach außen bewegbaren Zentrierkolben 5 deren äußere Enden als Teile der Mantelfläche des Traggehäuses 1 ausgebildet sind und in geeigneten öffnungen 6 in der Wand des Traggehäuses 1 angeordnet sind.A number, preferably an odd number, of radially directed pressure-actuated lifting cylinders 4 with centering pistons 5 which can be moved radially outward sit on the insert base 3, the outer ends of which are designed as parts of the lateral surface of the support housing 1 and are arranged in suitable openings 6 in the wall of the support housing 1.

Auf dem Einsatzboden 3 ist ein in Langlöchern 7 verstellbarer Festanschlag 8 vorgesehen, der an einer Seite der einzubringenden VerbaustUtze 2 anzugreifen vermag.Dem Festanschlag diametral gegenüber ist ein druckmittelbetätigter Spannkolben 9 angeordnet, der in einem an dem Einsatzboden 3 befestigten Zylinder 10 geführt ist und an der anderen Seite der Verbaustutze anzugreifen vermag.

zelnen Druckmittelzylindern 4,10 angeordnet.arranged individual pressure medium cylinders 4.10.

An der Unterseite des Einsatzbodens 3 sind ferner radial ausgerichtete Hubzylinder 12 mit Zentrierkolben 13 angeordnet, die durch Uffnungen 14 in der Wand des Traggehäuses nach außen bewegbar sind und im Wesentlichen wie die Zentrierkolben 5 ausgebildet sind. Diese Zentrierkolben 13 dienen der Grobzentrierung, die Zentrierkolben 5 an der Oberseite des Einsatzbodens 3 der Fein- oder Nachzentrierung.On the underside of the insert base 3 there are furthermore radially aligned lifting cylinders 12 with centering pistons 13, which can be moved outwards through openings 14 in the wall of the support housing and are essentially designed like the centering pistons 5. These centering pistons 13 are used for rough centering, the centering pistons 5 on the top of the insert base 3 for fine or subsequent centering.

Das Traggehäuse 1 weist an seiner Oberseite Tragösen 15 auf, in die Halteseile 16 eingreifen. Nach oben gehen ferner die notwendigen elektrischen Energieleitungen 17 und die für den Vor- und Rücklauf der Druckmittelzylinder bestimmten Druckmittelleitungen 18,19.The support housing 1 has on its upper side support eyes 15, into which the holding cables 16 engage. The necessary electrical power lines 17 and the pressure medium lines 18, 19 intended for the forward and return flow of the pressure medium cylinders also go up.

Die Fig. 4 bis 6 erläutern die Funktion der erfindungsgemäßen Vorrichtung.4 to 6 explain the function of the device according to the invention.

Neben dem lotrechten Erdbohrloch 20, in das eine Fundamentmasse 21 eingebracht ist, wird die erfindungsgemäße Vorrichtung 22 zunächst auf etwa 50cm hohen Holzklötzen oder dgl. aufgesetzt. Die Zentrierkolben 5 und 13 sind eingefahren, so daß die Mantelfläche des Traggehäuses 1 glatt ist. Die Halteseile 16 werden seitlich ausgelegt.In addition to the vertical earth borehole 20, into which a foundation mass 21 has been introduced, the device 22 according to the invention is first placed on approximately 50 cm high wooden blocks or the like. The centering pistons 5 and 13 are retracted so that the outer surface of the support housing 1 is smooth. The tethers 16 are laid out laterally.

Anschließend wird mittels eines Hebezeuges 23 eine Verbaustütze 2 von oben lotrecht in den lichten Raum zwischen dem Festanschlag 8 und dem Spannkolben 9 eingefädelt und auf den Boden gestellt. Nun wird der Zylinder 10 betätigt, so daß die Verbaustütze 2 fest eingespannt wird.Then, using a lifting device 23, a shoring support 2 is threaded vertically from above into the clear space between the fixed stop 8 and the tensioning piston 9 and placed on the floor. Now the cylinder 10 is actuated so that the shoring support 2 is firmly clamped.

Anschließend wird die Verbaustütze 2 mit der daran angeklemmten Vorrichtung 22 in das Erdbohrloch 20 eingebracht (Eig.5) und bis vor die Fundamentfüllung 21 abgesenkt. Die Halteseile 16 werden dabei von Hand nachgeführt.Subsequently, the shoring support 2 with the device 22 clamped thereon is introduced into the earth borehole 20 (Eig.5) and lowered to the foundation filling 21. The tethers 16 are tracked by hand.

Vor Erreichen der Fundamentfüllung 21 werden zunächst die Zentrierkolben 13 für die Grobzentrierung nach außen gegen die Wand des Erdbohrloches 20 gefahren. Anschließend erfolgt eine Feinzentrierung mittels der Zentrierkolben 5 unter Zuhilfenahme einer Wasserwaage oder eines Lasergerätes. Hat die VerbaustUtze 2 ihre vorbestimmte Stellung erreicht, wird die KLemmverbindung zwischen der Klemmeinrichtung 8,9 und der VerbaustUtze 2 gelöst. Die Verbaustütze 2 kann dann in die. FundamentfUllung 21 abgelassen werden und nimmt eine genau zentrierte Stellung im Erdbohrloch 20 ein. Die Verbaustütze 2 wird dann vom Hebezeug 23 gelöst.Before the foundation filling 21 is reached, the centering pistons 13 are first moved outwards against the wall of the borehole 20 for rough centering. Subsequently, fine centering is carried out by means of the centering piston 5 with the aid of a spirit level or a laser device. If the sheeting support 2 has reached its predetermined position, the clamping connection between the clamping device 8, 9 and the sheeting support 2 is released. The support column 2 can then in the. Foundation filling 21 are drained and takes a precisely centered position in the earth borehole 20. The shoring support 2 is then released from the hoist 23.

Anschließend werden die Zentrierkolben 5 und 13 eingefahren und die Vorrichtung 22 mittels der Halteseile 16 aus dem Erdbohrloch herausgezogen. Die Vorrichtung steht nun zum Einbringen der nächsten VerbaustUtze zur Verfügung.Then the centering pistons 5 and 13 are retracted and the device 22 is pulled out of the earth borehole by means of the holding cables 16. The device is now available for installing the next shoring.
