Definitions
- the present invention relates to a new chamber plate for trench shoring elements.
- trench shoring elements are used for the rolling excavation of manholes.
- the chamber plates are connected to each other with the help of toggle struts with spindles at the desired distance and channel boards are lowered into the ground between the walls of the chamber plates.
- guides are provided between the walls, which align and guide the channel boards provided with a hat profile and overlapping one another.
- the planks themselves are conventionally rammed into the ground to support the duct walls against earth pressure after excavation.
- EP-A-075 453 proposes a method for supporting trenches, in which the planks referred to there as support wall elements are pressed into the ground with the aid of drive beams guided in a frame.
- the support wall elements have a hole pattern into which gags are inserted, via which the beam force is transmitted.
- a disadvantage of this device is that it requires a high level of design effort to ensure the necessary stability, since the beam forces must be absorbed by the vertical frame parts in particular, and hydraulic power cylinders are required at both ends, the uniform loading of the cylinders being complex in terms of control technology.
- the object of the present invention is therefore to create a chamber plate for trench shoring elements which does not have these disadvantages, which is in particular safe to work with and requires only little construction, operation and costs.
- a chamber plate for trench shoring elements for the hydraulic pressing and pulling of channel boards with an outer wall and an inner wall arranged towards the trench, as well as guides for the channel boards with a hat profile in which, according to the invention, preferably a horizontal rail on the outer wall of the chamber plate is arranged, a hydraulic telescopic cylinder is releasably attached to the rail and the channel planks have a perforated grid in a vertical row into which a fastening means arranged on the hydraulic cylinder can be introduced.
- the operation of the device is as follows.

- the hydraulic cylinder is attached to the rail, which is preferably located on the outer wall, below the hole provided for anchoring for the tensile force, and the cylinder is moved downward hydraulically, taking the plank with it. Then the anchoring is released and either the next higher hole is grasped after the cylinder has been extended or the cylinder is brought to the next floorboard in order to press it into the ground in the same way. In this way, all boards are lowered one after the other or with several cylinders, for example opposite, at the same time, the channel is deepened in sections in order to lower the boards again to the final dimension.
- a significant simplification of work can be achieved according to the invention in that the hydraulic cylinder is arranged displaceably on the rail and is pivotably mounted on it, so that it only has to be pushed, secured and pivoted towards the proposed place on the board in order to achieve the desired lifting or lowering movement.
- the rail provided for securing the hydraulics is designed to be open at the top in a U-shape, a sword engaging in the intermediate region of the U-legs, on which there is a base plate which carries the cylinder.
- U-leg and sword have holes in which a locking bolt is inserted after the sword is aligned.

Abstract
Description
Die vorliegende Erfindung betrifft eine neue Kammerplatte für Grabenverbauelemente. Derartige Grabenverbauelemente dienen zum rollierenden Aushub von Kanalschächten. Dabei werden die Kammerplatten mit Hilfe von Knebelstreben mit Spindeln in gewünschtem Abstand gegenüberliegend miteinander verbunden und zwischen die Wandungen der Kammerplatten Kanaldielen in das Erdreich abgesenkt. Dazu sind zwischen den Wandungen Führungen vorgesehen, die die mit einem Hutprofil versehenen und einander überlappenden Kanaldielen gegeneinander ausrichten und führen. Die Dielen selbst werden herkömmlich durch Schläge in das Erdreich gerammt, um die Kanalwände nach dem Aushub gegen den Erddruck abzustützen.The present invention relates to a new chamber plate for trench shoring elements. Such trench shoring elements are used for the rolling excavation of manholes. The chamber plates are connected to each other with the help of toggle struts with spindles at the desired distance and channel boards are lowered into the ground between the walls of the chamber plates. For this purpose, guides are provided between the walls, which align and guide the channel boards provided with a hat profile and overlapping one another. The planks themselves are conventionally rammed into the ground to support the duct walls against earth pressure after excavation.
Nachteilig ist dabei, daß auf die umgebenden Gebäude die durch das Einrammen entstehenden Bodenschwingungen übertragen werden und der Umgang mit dem hierzu verwendeten Werkzeug ein erhebliches Gefährdungspotential darstellt.The disadvantage here is that the ground vibrations resulting from the ramming are transmitted to the surrounding buildings and the handling of the tools used for this purpose represents a considerable risk potential.
Aus diesem Grunde schlägt die EP-A-075 453 ein Verfahren zum Abstützen von Gräben vor, bei dem die dort als Stützwandelemente bezeichneten Dielen mit Hilfe von in einem Rahmen geführten Treibbalken in den Boden gedrückt werden. Dazu besitzen die Stützwandelemente ein Lochraster, in das Knebel eingeführt werden, über die die Balkenkraft übertragen wird.For this reason, EP-A-075 453 proposes a method for supporting trenches, in which the planks referred to there as support wall elements are pressed into the ground with the aid of drive beams guided in a frame. For this purpose, the support wall elements have a hole pattern into which gags are inserted, via which the beam force is transmitted.
Nachteilig bei dieser Vorrichtung ist, daß sie einen zur Gewährleistung der notwendigen Stabilität hohen konstruktiven Aufwand erfordert, da die Balkenkräfte von insbesondere den senkrechten Rahmenteilen aufgefangen werden müssen, und beidendig hydraulische Kraftzylinder erforderlich sind, wobei das gleichmäßige Beaufschlagen der Zylinder regelungstechnisch aufwendig ist.A disadvantage of this device is that it requires a high level of design effort to ensure the necessary stability, since the beam forces must be absorbed by the vertical frame parts in particular, and hydraulic power cylinders are required at both ends, the uniform loading of the cylinders being complex in terms of control technology.
Die vorliegende Erfindung hat sich daher die Aufgabe gestellt, eine Kammerplatte für Grabenverbauelemente zu schaffen, die diese Nachteile nicht aufweist, die insbesondere arbeitssicher ist und nur geringen Konstruktions-, Bedienungs- und Kostenaufwand erfordert.The object of the present invention is therefore to create a chamber plate for trench shoring elements which does not have these disadvantages, which is in particular safe to work with and requires only little construction, operation and costs.
Die Lösung dieser Aufgabe gelingt bei einer Kammerplatte für Grabenverbauelemente für das hydraulische Einpressen und Ziehen von Kanaldielen mit einer Außenwandung und einer zum Graben hin angeordneten Innenwandung sowie Führungen für die ein Hutprofil aufweisenden Kanaldielen, bei welcher erfindungsgemäß vorzugsweise an der Außenwandung der Kammerplatte eine waagerecht verlaufende Schiene angeordnet ist, auf der Schiene ein hydraulischer Teleskopzylinder lösbar befestigt ist und die Kanaldielen ein Lochraster in senkrechter Reihung besitzen, in die ein am Hydraulikzylinder angeordnetes Befestigungsmittel einbringbar ist.This problem is solved with a chamber plate for trench shoring elements for the hydraulic pressing and pulling of channel boards with an outer wall and an inner wall arranged towards the trench, as well as guides for the channel boards with a hat profile, in which, according to the invention, preferably a horizontal rail on the outer wall of the chamber plate is arranged, a hydraulic telescopic cylinder is releasably attached to the rail and the channel planks have a perforated grid in a vertical row into which a fastening means arranged on the hydraulic cylinder can be introduced.
Gegenüber einer herkömmlichen, nicht hydraulisch arbeitenden Kammerplatte ist lediglich eine zusätzliche waagerechte Schiene vorzusehen, an der der hydraulische, auf Druck und Zug belastbare Teleskopzylinder unterhalb der Lochreihen der Kanaldielen angebracht werden kann. Dies erfordert nur geringen Konstruktions- und Fertigungsaufwand, da die Außenwandung der Kammerplatte ohne weiteres in der Lage ist, die zum Einpressen oder Herausziehen der Dielen notwendigen Kräfte aufzunehmen. Unter dem Ausdruck Schiene soll daher auch jedes gleich wirkende Befestigungsmittel für den Hydraulikzylinder, wie etwa eine Reihe von separaten Befestigungsmitteln, verstanden werden.Compared to a conventional, non-hydraulic chamber plate, only an additional horizontal rail has to be provided, on which the hydraulic telescopic cylinder, which can withstand pressure and tension, can be attached below the rows of holes in the channel planks. This requires only little construction and manufacturing effort, since the outer wall of the chamber plate is readily able to press or pull out the planks To absorb forces. The term rail should therefore also be understood to mean any fastening means for the hydraulic cylinder which have the same effect, such as a number of separate fastening means.
Die Arbeitsweise der Vorrichtung ist folgende.The operation of the device is as follows.
Zunächst wird die Kammerplatte an den Ort des beabsichtigten Kanalaushubs gebracht und über mit Spindeln versehene Knebelstreben mit einer weiteren Kammerplatte, wie bekannt, zu einem Kammerverbauelement verbunden. Danach werden die Kanaldielen in die Führungen der Kammerplatten senkrecht stehend eingeführt, wobei die Bestückung vorzugsweise vollständig und beidseitig erfolgt.First, the chamber plate is brought to the location of the intended channel excavation and connected to a further chamber plate, as is known, to form a chamber shoring element via toggle struts provided with spindles. The duct boards are then inserted vertically into the guides of the chamber plates, the assembly preferably being complete and on both sides.
Die Kanaldielen lehnen an den Kammerplattenwandungen an, wodurch die Kammerplattenlast auf den Boden wesentlich erhöht wird.The channel planks lean against the chamber plate walls, which increases the chamber plate load on the floor significantly.
Der Hydraulikzylinder wird an der vorzugsweise an der Außenwandung befindlichen Schiene unterhalb des zur Verankerung für die Zugkraft vorgesehenen Loches befestigt und der Zylinder hydraulisch unter Mitnahme der Diele nach unten bewegt. Sodann wird die Verankerung gelöst und entweder nach vorherigem Ausfahren des Zylinders das nächst höhere Loch erfaßt oder der Zylinder zur nächsten Dielen gebracht, um diese in gleicher Weise in das Erdreich zu drücken. Derart werden alle Dielen nacheinander oder auch mit mehreren Zylindern, z.B. gegenüberliegend, zeitgleich abgesenkt, der Kanal entsprechend abschnittsweise vertieft, um die Dielen erneut bis auf das Endmaß abzusenken.The hydraulic cylinder is attached to the rail, which is preferably located on the outer wall, below the hole provided for anchoring for the tensile force, and the cylinder is moved downward hydraulically, taking the plank with it. Then the anchoring is released and either the next higher hole is grasped after the cylinder has been extended or the cylinder is brought to the next floorboard in order to press it into the ground in the same way. In this way, all boards are lowered one after the other or with several cylinders, for example opposite, at the same time, the channel is deepened in sections in order to lower the boards again to the final dimension.
Beim Herausziehen der Dielen wird umgekehrt verfahren, wozu der Zylinder um sein Hubmaß ausgefahren und die Diele in angehobener Stellung gegen Herunterrutschen gesichert wird. Um den Hydraulikzylinder bzw. dessen kopfseitiges Befestigungsmittel in den Dielenlöchern zu sichern, wird vorgeschlagen, hierzu einen oben und unten geschlitzten, senkrecht zur Zylinderachse angeordneten Bolzen zu verwenden.When pulling out the planks, the procedure is reversed, for which the cylinder is extended by its stroke dimension and the plank is secured in the raised position against slipping down. In order to secure the hydraulic cylinder or its head-side fastening means in the plank holes, it is proposed to use a bolt that is slotted at the top and bottom and arranged perpendicular to the cylinder axis.
Eine wesentliche Arbeitserleichterung läßt sich erfindungsgemäß dadurch erreichen, daß der Hydraulikzylinder verschieblich auf der Schiene angeordnet und schwenkbar auf dieser gelagert ist, so daß dieser lediglich zur vorgeschlagenen Stelle an der Diele geschoben, gesichert und zur Diele hin geschwenkt werden muß, um die gewünschte Hub- oder Senkbewegung durchzuführen.A significant simplification of work can be achieved according to the invention in that the hydraulic cylinder is arranged displaceably on the rail and is pivotably mounted on it, so that it only has to be pushed, secured and pivoted towards the proposed place on the board in order to achieve the desired lifting or lowering movement.
Beim Anheben der Kanaldielen sind diese gegen Herabrutschen an der Kammerplatte zu sichern.When lifting the duct boards, they must be secured against slipping down on the chamber plate.
Da sich aber beim Bedienen des Zylinders dieser vor der Lochreihe befindet, ist der Zugang in diesem Bereich erschwert. Es müßte daher ein darüber- oder darunterliegendes Loch zur Sicherung herangezogen werden. Um diesen Sicherungsvorgang zu erleichtern, wird vorgeschlagen, die Dielen mit mindestens zwei parallelen Reihen von Löchern zu versehen und diese mit Hilfe von Durchsteckbolzen auf dem oberen Rand der Kammerplatte zu sichern.However, since the cylinder is in front of the row of holes when it is operated, access in this area is difficult. A hole above or below it would therefore have to be used for securing. In order to facilitate this securing process, it is proposed to provide the planks with at least two parallel rows of holes and to secure them with the aid of push-through bolts on the upper edge of the chamber plate.
In besonders bevorzugter Ausführungsform ist die zum Sichern der Hydraulik vorgesehene Schiene nach oben offen U-förmig ausgebildet, wobei in den Zwischenbereich der U-Schenkel ein Schwert eingreift, auf dem sich eine Bodenplatte befindet, die den Zylinder trägt.In a particularly preferred embodiment, the rail provided for securing the hydraulics is designed to be open at the top in a U-shape, a sword engaging in the intermediate region of the U-legs, on which there is a base plate which carries the cylinder.
U-Schenkel und Schwert weisen dabei Bohrungen auf, in die nach fluchtender Ausrichtung des Schwertes ein Sicherungsbolzen eingeführt wird. Die Schiene besitzt dabei in gleicher Weise wie die Dielen ein hier jedoch waagerechtes, nach den Dielenmaßen und den Führungen ausgerichtetes Lochraster.U-leg and sword have holes in which a locking bolt is inserted after the sword is aligned. In the same way as the planks, the rail has a perforated grid that is horizontal here, aligned with the plank dimensions and the guides.
Anstelle der Sicherung zur Aufnahme der Zugkräfte durch Lochung und Bolzen kann die U-Schiene auch profiliert sein und ein entsprechend gegensinniges Profil des Schwertes etwa schwalbenschwanzartig übergreifen.Instead of securing the tensile forces through perforation and bolts, the U-rail can also be profiled and overlap a correspondingly opposing profile of the sword, for example in the form of a dovetail.
Nach dem Aushub des durch das Verbauelement festgelegten Kanalabschnittes und Verlegung oder Reparatur von Rohren oder dergleichen kann dieser unter Bodenverfestigung und Herausziehen der Dielen aufgefüllt werden, um mit demselben Verbauelement den nächsten Abschnitt zu bearbeiten. Dazu muß das Verbauelement um seine Länge vorwärtsbewegt werden. Um dies zu erleichtern wird vorgeschlagen, die Kammerplatte mit Rollen zu versehen und diese auf daruntergelegten Blechen zu verfahren.After excavation of the channel section defined by the shoring element and laying or repairing of pipes or the like, this can be filled up while consolidating the soil and pulling out the planks in order to work on the next section with the same shoring element. To do this, the shoring element must be moved forward by its length. In order to facilitate this, it is proposed to provide the chamber plate with rollers and to move these on the metal sheets underneath.
