Definitions

  • the invention is based on a method for shoring deep trenches by means of support frames which can be set up transversely to the trench in the longitudinal direction of the trench and which are composed of two parallel supports and a rigid stiffening frame which keeps the supports at a distance and connects and which can be displaced along the supports, and by means of large-area shoring plates, which are guided and held vertically displaceably on both sides of the trench with their vertical edges in guide channels of the supports of two support frames and are pressed or lowered into the trench in the support frame and the shoring plates, following the trench excavation.
  • a shoring plate can be inserted into the supports of two support frames set up at a distance from one another on each trench side. So that the stiffener frame does not shift relative to the supports when a support frame is set up, holes are provided in the supports and in the parts of the stiffener frame guided in the supports, which can be fixed against one another by means of a bolt.
  • the length of the supports is about twice as high as the height of the stiffener frame, the stiffener frame being arranged only in the upper region of the support frame, so that there is enough free space for the excavator bucket below the stiffener frame.
  • This device is not suitable for shoring very deep trenches because the shoring plates would also have to be very high and this would cause difficulties when dismantling the shoring device and because when erecting and inserting a support frame the upper stiffness of the stiffening frame is very high, making it very difficult is to reach over this top stiffener with the backhoe.
  • a shoring device in which the stiffener frame is composed of three or more individual frames.
  • the stiffener frame is high in relation to the height of the supports, so that when the support frame is erected, an excavator has difficulties in reaching over the stiffener frame with its spoon.
  • a shoring device in which two struts that keep the supports at a distance are connected via vertical struts to form a rigid rigid frame.
  • This stiffener frame can be moved in the supports. Because the rigid frame is guided in the supports via relatively short guide heads, moving the rigid frame under load is problematic. So that after the support frame is set up, the stiffener frame does not slide down, it is fixed at the required height using retaining bolts.
  • support frames are customary which are composed of two supports and two or more spreaders which run for digging and are articulated to the supports.
  • the stability of this support frame is achieved via pre-tensioned springs, which are arranged between the supports and the struts.
  • These support frames have the disadvantage that the supports can only be moved in the longitudinal direction by a relatively small amount compared to the other support. If one of the supports is pulled during the dismantling while the other support remains standing, the resulting inclination of the spreaders reduces the distance between the supports. As a result, the floor can slide. If the opposite support is then pulled, the slid floor must be pushed back, which makes very high lifting forces of the excavator necessary.
  • the object of the invention is to further develop it in such a way that even deep and very deep trenches can be reliably installed and the shoring device can be dismantled without the use of extremely great forces and in which lighter excavators are used despite the large trench depth can be.
  • the rigid frame between a lower stop and an upper stop is slidably guided on the supports, the lower stop at the level of the necessary excavator bucket freedom about 1 to 1.50 m from the support foot and the upper stop is arranged at a distance from the lower stop, which is the height of the rigid frame, for example 1.75 m, and a permissible prop jacking, e.g.
  • the upper stops are removed, a second stiffener frame is inserted into the supports of the support frame and the upper stops are attached to the supports at a distance above the second stiffener frame and that after lowering the support frame by a further stiffener frame height, the upper stops are removed and, if necessary, a third stiffener frame is inserted into the supports of the support frame and that the stiffener frames are connected to one another in order to dismantle the support frame.
  • the shoring method according to the invention and the device for carrying out this method are intended for shoring trenches 5 to 10 meters deep, although trenches less deep can be built in the same way.
  • the supports are provided with three or four guide channels on each side to accommodate the edges of the shoring panels. Accordingly, the excavated trench has two or three levels. Because, despite the great height of the supports, they are reliably held by only one rigid stiffening frame, the excavator boom can comfortably reach over this stiffening frame at the beginning of the trench excavation, the upper edge of which is in any case less than 2.50 m above the ground. This amount results from the following values: Depth of the lining - 1.00 m Height of the lower stop + 1.50 m Height of the stiffener frame + 1.70 m 2.30 m
  • the supports can be driven independently of each other, the upper stop takes the rigid frame with them so that the free cantilever length in the lower area of the supports is not exceeded.
  • the two shoring panels running inside are inserted into the guide channels of the supports.
  • the stiffener frame has been lowered to below the top edge of the earth due to its height (approx. 1.70 m)
  • the second stiffener frame is now inserted into the supports after fixing the upper stops and attached to the lower one. This attachment takes place with consideration of the dismantling.
  • the upper stops must be reassembled with the same stroke. Now the lowering of the inner plates and the supports can be continued. Because the stiffening frames can be pushed as required (depending on the total depth), the excavator with standard stick can be dredged cleanly and evenly over the frame between the shoring.
  • the supports and the mounting plates are designed so that at least two mounting plates and, if necessary, three or four mounting plates can be inserted on each side of the support.
  • the new shoring device has the advantage that it is possible to work with lighter excavators, that deeper trenches can be built economically than before, and that work can be carried out faster and with less interference if the trenches are less deep.
  • the device shown in FIGS. 1 to 3 is used to block trenches over 6 meters deep. It has support frames which can be set up at equal intervals in the longitudinal direction of the trench and which are each composed of two parallel supports 1, 2 and a rigid frame 3 which keeps the supports 1, 2 at a distance and connects them.
  • the stiffener frame 3 is displaceable along the supports 1, 2.
  • the support frames 1, 2, 3 and the shoring panels 4, 5 are lowered into the trench following the trench excavation or pressed into the trench with the excavator bucket.
  • the support feet and the lower longitudinal edge of the shoring plates 4.5 are provided with cutting edges 13, which ensure that when the supports 1, 2 and shoring plates 4.5 are lowered, the protruding soil on the trench wall falls inwards into the trench.
  • These known cutting edges 13 cause that when driving the supports 1, 2 these are not pressed from the ground towards the center of the trench, but remain vertical and are lowered parallel to one another.
  • the rigid frame 3 is slidably guided on the supports 1, 2 between a lower stop 6 and an upper stop 7.
  • the lower stop 6 is attached at the level of the necessary excavator bucket clearance approx. 1 to 1.50 m from the lower end of the support.
  • the upper stop 7 is arranged at a distance from the lower stop 6, which corresponds to the height of the rigid frame 3 and an allowable prop jacking.
  • the stops 6 and 7 are easily displaceable and can be inserted into recesses 14 which are arranged one above the other in rows in guide rails 11 of the supports 1, 2.
  • the upper stops 6 are removed and a second stiffening frame 3 inserted into the supports 1 and 2 of the support frame.
  • the upper stops 7 are fastened to the supports 1, 2 at a distance above the second rigid frame 3.
  • the upper stops 7 are removed again and, if necessary, a third stiffener frame 3 is inserted into the supports 1, 2 of the support frame. (cf. Fig. 1 C)
  • the stiffener frames 3 are easily detachably connected to each other, so that by pulling up the upper stiffener frame, the stiffener frames 3 connected below also follow.
  • the dismantling of the stepped sheeting is carried out in the same way as the installation, ie after the pipes have been inserted, soil is poured in layers, up to max. Lower edge of the lower stiffening frame 3. Then stiffening frame 3, sheeting plates 4.5 and supports 1.2 to the newly created level. If you have dismantled to the corresponding level, the inner shoring plates 5 and after removing the upper stops 7, the upper rigid frame 3 can be removed from the shoring unit. Then the upper stops 7 are attached over the last rigid frame 3 and the support frame 1, 2, 3 is pulled out of the essentially filled trench. The support frame 1, 2, 3 can then be used again on the trench head.
  • the shoring device can also be dismantled in such a way that, after the stops 6 and 7 have been removed, only the shoring plates 4, 5 and the rigid frame 3, following the backfilling, are pulled upwards .
  • the smooth supports 1, 2 can be pulled out individually.
  • the excavator can be moved up to the supports 1, 2 so that it can pull out the support 1, 2 with the greatest force available to it.
  • the cavity and the guide channels 8, 9 of the supports 1, 2 can be filled with sand or gravel.
  • a support 1 is placed horizontally on the floor with its back. Then the lower stop 6 is inserted at the required height into a receptacle 14 in the row of holes on the support 1.
  • the stop height can be 1 m to 1.50 m from the column foot 13, so that the excavator can reach with its digging vessel under the rigid frame 3 and can cut the trench between the columns 1, 2 to further lower the columns.
  • the stiffener frame 3 is inserted horizontally from the support head side with its rail 12 into the guide rail 11 of the support 1.
  • the second support 2 is inserted horizontally into the opposite rail 12 of the rigid frame 3.
  • the distance of the lower stop 6 to the upper stop 7 should be about 0.5 m higher than the height of the rigid frame 3.
  • the stop 7 limits the pushing of a support 1 or 2, so that the free cantilever length of the supports 1,2 does not exceed their maximum value can come. In this way, the first column frame is created.
  • the other support frames are constructed accordingly.
  • part of the trench is excavated, namely in the width of the support frame 1, 2, 3 and to a length of 1 x shoring plate length plus the width of a support (for example 0.5 m).
  • the excavation takes place at a depth of approx. 1 m.
  • the first support frame 1, 2, 3 is set using a chain sling and an excavator.
  • the chain sling is attached to the support heads.
  • the rigid frame is held by the lower stops 6.
  • the two outer upper shoring plates 4 are inserted into the guide channels 8 of the supports 1 and 2 of the first support frame and aligned parallel to the trench axis.
  • a second support frame with the guide channels 8 is then threaded over the edges of the shoring panels 4 pointing towards the excavator.
  • the first shoring panel is now in place and excavation of the trench can begin. Since the upper edge of the rigid frame 3 is lower than 2.50 m above the ground, a relatively small excavator can reach over the rigid frame and dig a deep trench.
  • the upper ends of the guide rails 11 are widened like a funnel and the side rails 12 of the step frame 3 are on the lower and upper corners 29 beveled.
  • you can 12 guide plates 27 and 28 can be arranged at the upper end of the guide rail, which facilitate the insertion of the rails 11 of the rigid frame 3 into the guide rails 12 of the supports 1, 2.
  • These baffles 27, 28 are arranged on the supports 1, 2 such that the insertion of the shoring plates 4, 5 into the inner guide channels 9 is not hindered. In Fig. 3, these baffles 27,28 are omitted.
  • FIG. 3 shows a view of the upper part of a support 1 with two guide channels 8, 9 on each side and on the wall facing the trench, a guide rail 11 which receives a lateral rail 12 of the rigid frame 3.
  • the support 1 shown is designed so that the edges of both the outer shoring panels and the inner shoring panels can be positively received in the longitudinal direction of the trench by the guide channels 8 and 9.
  • a sleeve 23 is arranged, in which the hook of a chain sling can be hooked.
  • the rigid frame 3 is also provided with a sleeve 24 for hanging a hook.
  • the stiffening frame 3 consists of horizontally and vertically extending hollow box sections 33 and 34. In the corners of the merging hollow sections 33 and 34, corner stiffeners 35 are arranged so that the stiff frame receives a very high rigidity and the lateral rails 12 of the stiffening frame even with relatively thin wall thicknesses Remain completely parallel even under the highest loads.
  • narrow sliding ribs running lengthwise are arranged on the parts of the guide rail 11 clasping the rail 12, which come into play with play on the back of the rail 12.
  • On both sides of the guide rail 11 are on the guide rail 11 or on the Rail 12 of the rigid frame 3 fixed sliding strips 32 are arranged, which are wide compared to the narrow sliding ribs 31 because they have to transfer the large loads from the supports to the rigid frame.
  • the sliding strips are made of a material with very good sliding properties. The distance between these sliding strips should be as large as possible and larger than the support lines of the edges of the shoring panels 4 and 5 in the supports 1 and 2. This measure has the advantage that when the supports 1 and 2 are loaded on one side, no torque is applied to the supports 1 and 2 acts.
  • two guide channels are not provided on both sides of a support 1 ', but only one guide channel 8' each, which is formed by a support flange 50 and a guide flange 51. Both the outer shoring panels 4 'and the inner shoring panels 5' are guided in this guide channel 8 '. Both shoring plates 4 'and 5' are supported by support webs 52 and 53 on the support flange 50 of the support 1 '. The shoring plates 4 'and 5' are designed differently. The outer shoring plates 4 'are somewhat wider and have a relatively long support web 52 which surrounds the inner shoring plate 5'.
  • the edge of the outer shoring plates 4 ' is positively guided in the longitudinal direction of the trench in the guide channel 8' of the support 1 '.
  • the inner shoring plates 5 ' are supported on the support flange 50 via the support web 53.
  • the support flange 50 is reinforced by the guide rail 11.
  • a side flange 56 is angled from the support flange 50 in such a way that support rollers are arranged one above the other between this side flange 56 and the side walls 58 of the support 1 ' 57 can be arranged, on which the supporting webs 52 and 53 of the shoring panels 4 'and 5' run.
  • the four corners of the shoring plates 4 'and 5' are open towards the narrow sides of the shoring plates 4 'and 5' pocket-like housing 58 arranged in which rollers 54 and 55 are mounted.
  • the rollers 54 roll on the side walls 59 of the supports 1, while the corner rollers 55 of the inner sheeting panels 5 'run on the outer sides of the side flanges 56.
  • These corner rollers 54 and 55 prevent the shoring panels between the supports of this shoring wall from tilting during the relative movement of a support of a loaded shoring wall.
  • the stops 6 and 7 which can be inserted below and above the rigid frame 3 into the recesses 14 of the guide rail 11 have an insert 15 which is adapted to the rectangular cross section of the recess 14.
  • the stops 6 and 7 are provided with a lock 16 which can be pivoted through 90 ° and which can be pivoted into the open position and the closed position via a shaft 17 passing through the insert piece 15 and a lever 18.
  • the lever 18 is designed so that it presses the bolt 16 into the locked position when a rigid frame abuts the stop 6 or 7. Since relatively large forces can act on the stops 6 and 7, it has a hook-like extension 19 with a second insert 20 which can be inserted in a second recess 14 in the row of holes.
  • a nose 21 engages behind the guide rail 11.
  • the stop 6 or 7 or the extension 19 is provided with a bow-shaped handle 22 with which the stop can be easily inserted into the recess 14 in the guide rail 11. 8 and 9 show the stop 6 in the locked position.
