The invention relates to a shoring device for supporting stepped walls of a trench, consisting of

• vertical supports to be arranged in pairs at equal intervals along the trench,
• the supports of a pair of supports at a distance from spreading devices,
• Large-area outer and upper shoring panels, the edges of which are guided in a form-fit, vertically displaceable manner in the guide channels of the supports
• Large-area inner and lower sheeting panels, the edges of which are guided so that they can be moved vertically in the guide channels of the supports.

Devices of this type are known from DE-A-42 30 860.

With the help of these shoring devices can be very deep Trenches of 7 - 12 m depth reliably installed , it being possible without difficulty during the backfill of the trench, the shoring plates, the supports and the trench spreaders for reuse pull out.

With such shoring devices, there are problems if Lines running across the trench require the use of large areas Make shoring plates impossible. In the area of such lines running across the trench are so-called Floorboard elements used, for example from the DE-A-30 07 956 are known. These floorboard elements exist from two chamber plates, which are spread over Be kept clear. Be inside the chamber plates side by side, as gapless as possible, vertical planks slidably guided. The one acting on the channel planks Earth pressure is provided by the inner plate and there Straps of the plank chamber plate caught.

In the case of very deep trenches, long channel planks must be used be used. With these long channel planks on the one hand the difficulty of getting this into the plank board and following the excavation downwards to press. Furthermore, the load on the channel planks is also Earth pressure from the inner panels of the plank chamber panels is very big to record.

The invention has for its object a shoring device to create that it avoids with cross lines, to have to use two types of shoring systems and in which it is possible, even in the area of cross lines Trench walls to be reliably installed.

This object is achieved in that starting from the shoring device described at the beginning, in the area of a cross line instead of an outer and upper shoring plate in the guide channels of two adjacent supports one upper plank chamber plate is inserted, in which side by side vertical duct boards used and vertically movable are led.

With the help of the shoring device according to the invention it is possible, even in the area of a cross line that of length a shoring field corresponding to a shoring panel by means of duct boards reliable to install with the exception of the relative narrow area below the cross line.

So that this area is also at least largely obstructed can be in further development of the invention suggested that instead of an inner and lower shoring panel a lower one in the guide channels of the supports Floor board can be used in which side by side Channel boards can be used and guided vertically are. The lower plank chamber plate can because of Cross line not from above into the guide channels of two adjacent supports on one side of the trench are introduced, but the plank chamber plate must be in the longitudinal direction of the trench below the cross line in the guides of the supports be used. This can be done in that the lower plank chamber plate at an angle of, for example, 30 ° inclined between the two supports at a distance inserted and then brought into a horizontal position, so that the lower plank chamber plate behind the guide flanges of the supports grab. But it is also possible that the web engaging in a guide channel of the lower plank chamber plate horizontally displaceable with the lower plank chamber plate is connected so that after insertion of a Web the plank chamber plate in the guide channel one Support the opposite bridge by moving it horizontally in the guide channel of the opposite pillar is inserted. Finally, it is also possible a web reaching behind a support flange of a support the guide plate is easily detachable with the lower plank chamber plate connect to. This easily detachable bridge can together with an associated stop part to the Support flange of a support are clamped and then after Insert the lower plank chamber plate into the guide channel the other support the plank chamber plate against that Fold the stop part so that attached to the stop part Bolts in corresponding holes in the lower plank chamber plate to grab. Via plug pins, wedges or The folded plank chamber plate can then be screwed with be connected to the stop part.

Further features of the invention emerge from the patent claims 3 to 9.
