Definitions
- the invention relates to a support for trench lining devices that are composed from along at intervals and perpendicular to both sides of a trench supports to be arranged, keeping the supports of a pair of supports at a distance Spreading frame and guided vertically displaceably in the side guides of the supports Sheeting panels, the support being a hollow box section running from top to bottom has and at its lower end with a wedge-shaped support foot is provided, which is a cutting edge located in the plane of the outer wall of the support and one that runs obliquely upwards from the cutting edge to the inside of the support, the box hollow profile bottom closing element has.
- the trench becomes especially filled with the excavation and brought back the parts of the shoring device.
- This dismantling takes place in such a way that earth up in several stages filled to a height of approx. 50 cm, then the shoring panels by about raised the same amount and then the filled soil using vibrating planks or similar compaction devices against the grown soil becomes.
- This filling of soil, pulling up the shoring panels and compacting the earth repeats itself from level to level.
- the supports are also included to pull up so that there was no space in the space the supports had occupied Forms cavity. Careful compaction of the filled soil is necessary so that settlement damage is avoided and the load-bearing capacity of the filling is increased.
- the invention has for its object a support for trench shoring devices to create of the type mentioned, with the help of which the proper Filling and compacting the trench and dismantling the trench shoring device is relieved.
- closure plate easily is releasably held on the support foot and that at least in the area of the upper end the support has a filling opening opening into the hollow box section.
- the closing plate can be on Column feet are removed.
- the support can be filled with soil, so that when the support is pulled up filled material comes out of the column foot. This emerging material can be compacted together with the other stages of backfilling.
- the shoring panels can be used first and the spreader frames are removed so that the supports are completely relieved become. Before pulling the supports, they are covered with a tightly falling preferably filled with dry material.
- the material to be filled in the supports according to grain shape, grain composition, degree of non-uniformity, surface quality, the water content and the admixtures are such that its compactibility is low and the free-falling material high Percentage of Proctor density reached.
- the fully relieved support can be pulled out without difficulty. This occurs the tightly falling or self-compacting material on the column base so that there are no voids and there is no risk of subsidence.
- the column cavity extends to the lower end of the columns out, so that when the support is raised, the filled material from the Outrigger comes out.
- the trench shoring device shown in FIG. 1 is composed Support 1,1 'at intervals along the trench on both sides of the trench are to be arranged, from expansion frame 2, which supports 1, 1 'of a pair of supports Keep distance and from shoring plates 3 and 4, which in the side guides 5 of Supports 1,1 'are guided vertically.
- the shoring plates 3 and 4 drawn in phantom lines are offset from one another in the supports 1,1 'guided so that they can slide past each other.
- the supports 1, 1 ' have a top to bottom continuous box hollow profile 10.
- the lining plates 4 are from the edge profiles of the upper outer Sheeting panels 3 encompassed.
- the supports 1, 1 ' are wedge-shaped at their lower ends Support foot 8 provided, one in the plane of the outer wall 16 of the support 1st located cutting edge 9 and one of the cutting edge 9 obliquely upwards to the inside the support 1 extending, the box hollow section 10 below closing plate 11 has.
- This closure plate 11 is used so that when driving in Do not support 1,1 'in the ground made up of stones, earth and clay Graft in the box hollow section 10. In the known supports, this closure plate always welded on. In the support 1 according to the invention, this is Locking plate 11 is easily detachably or removably attached to the column foot 8.
- the closure plate is in the support 1 according to the invention 11 via guide rails 14 on the outer sides of the side walls of the hollow box section 10 are attached, and holding rails 15, which the guide rails spill over to the interior of the trench and held guided.
- a bolt 13 is used, the locking plate 11 in the closed position holds. Only after the trench sheeting has been completed is the closure plate 11 pulled away by opening the latch 13 to the interior of the trench. It serves for example a hook 24, which in an eyelet attached to the closure plate 11 12 engages.
- the bolt 13 can be held in the closed position by a spring and be opened against the action of this spring.
- FIG. 6 shows, are on the outer wall 16 of the support 1 at intervals one above the other Recesses 17 arranged for hooking a traction device with which the Support 1 is pulled up during dismantling.
- a Filling funnel 18 can be used, which has a spout 19 which can be inserted into the recesses 17 having.
- brackets 20 which are pivotable are hinged to the hopper 18, the funnel 18 can be attached to the support 1 are by pivoting the brackets 20 so that they the guide flanges 24 reach behind the support 1.
- the striking plate 7 welded onto the upper end of the support 1.
- the filling funnel 18 can also support 1 at recesses 17 arranged lower the support 1 can be used.
- the Striking plate 7 'of the support 1' can be removed or opened.
- the hopper 18 ' can be placed on the open upper end of the support 1' become. So that the hopper is held reliably, it has a spout, which essentially corresponds to the inner cross section of the hollow box section 10 of the support 1 ' corresponds.
- an attachment edge 23 is also provided, with which the filling funnel 18 'is placed on the upper end of the support.
- the cross section of the hollow box section 10 becomes the lower one End of the support larger. In this way, bridging of the filled Material avoided and ensured that the filled material from the The column foot comes out when the column is raised. Because the outer wall 30 of the The support and the side walls of the hollow box section 10 are vertical Inner wall 31 inclined in the lower region so that the cross section is larger downwards becomes. The lower region with the inclined inner wall 31 extends over 2 to 3.5 m, because the spreading frame 2 is guided above this area in the support and the space of the expansion frame guide 6 for the outward inclination of the inner wall 31 is available.
