Definitions
- the invention relates generally to the field of wastewater technology.
- trenches composed of a plurality of trench units are increasingly being used, particularly in larger towns and cities. These rigs form an underground water basin, which is connected on the inlet side with at least one gully.
- the inlet can also be formed by a downpipe, which initiates the rainwater collected on roofs in the trench.
- the collected on the sealed surface rainwater is the trigole optionally supplied by an upstream feed system, which may include a pre-purification of the wastewater.
- the bottom surface of the trench may be liquid-permeable, so that the rainwater supplied to it can seep into the soil below it.
- the trench assembly can be connected to the sewage system in order to be able to prevent backflow to the surface when the accumulated rainwater quantity exceeds the absorption capacity of the soil and the trench arrangement.
- EP 1 260 640 A1 of the Applicant discloses a rectangular trench unit composed of two identical trench subunits which is outstandingly suitable for forming such triggers.
- An advantage of this trench unit is that the volume of the trench unit usable for water storage is very close to the total volume of the trench unit. Since the trench units known from EP 1 260 640 A1 are transported to the construction site in the fully assembled state, this advantage also represents a disadvantage at the same time, since the load-bearing capacity the lorries used for transport (lorries of the Jumbo class with a load carrying capacity of 14 t) can only be used to a small extent despite full utilization of the loading volume. Thus, in particular for larger construction projects, a large number of loads is required in order to transport the required number of trench units to the construction site. This of course is reflected in the price of the delivered rigging units.
- a trench unit comprising at least one trench sub-unit, the at least one trench sub-unit having a base wall and a plurality of hollow columns which are integrally connected to the base wall and away from the base wall, i. from its base end to its tip end, taper, preferably conically tapered.
- the columns of a plurality of trench sub-units can be inserted into one another for transport, so that overall results in a very compact transport arrangement, which effectively utilizes the load carrying capacity of the truck with fully loaded load volume.
- the columns are designed and / or the wall thickness and the degree of taper or taper angle of the columns are dimensioned such that in the stacked state of two identically oriented and identically designed Rigolenunterritten the Base walls of the two trench sub-units have a distance from each other which is smaller than the thickness of the base wall, preferably smaller than half the thickness of the base wall, wherein it is even more preferable if the base walls of the two trench sub-units abut each other.
- the distance between the base walls is understood to be the distance between the upper surface of the base wall of the lower stanchion subunit in the stacking direction and the lower surface of the base wall of the upper stanchion subunit in the stacking direction.
- the thickness of the base wall refers to the distance between the upper surface and the lower surface of the base wall of the same trench sub-unit.
- the spaces between adjacent columns are free of these connecting elements, in particular are free of connecting walls.
- the rigging unit In order for the rigging unit to forward forces acting on it in a horizontal direction to adjacent trench units, it is necessary that adjacent trench units rest laterally against each other.
- the trench units according to the invention do this with the peripheral surfaces of their base walls. For this reason, it is advantageous to form the peripheral surface of the base wall of the trench unit as high as possible.
- a third consideration to consider is the load-carrying capacity of the trucks used for transport to the job site. In the interplay of these three aspects, it has proved to be advantageous to form the peripheral wall of the base surface higher than the rest of the base wall.
- the base wall has a peripheral surface which extends to more than 50% of the circumference of the base wall by a predetermined distance beyond the remaining surface of the base wall, wherein the predetermined distance, for example, is smaller than the thickness of the base wall, preferably smaller is less than half the thickness of the base wall.
- the base wall may have a height of 5 cm, while the remaining base wall has a height or thickness of 4 cm.
- lateral stiffening ribs which support at least one column, preferably a plurality of columns, more preferably all columns, at their base end against tilting, extend only within the height of the base wall.
- marginal and rectangular columns have a predetermined distance from the edge of the base wall.
- this predetermined distance which may be for example between about 1 cm and about 5 cm, is also in the edge region of the base wall sufficient space available to order the stiffening ribs distributed even at marginal and eck receivingn columns over the entire circumference.
- the interior of the plurality of pillars be reinforced at most in a height region adjacent to the tip end whose height corresponds to the thickness of the base wall.
- reinforcing struts having.
- At least one column comprises two cones arranged one inside the other, the directions of their tapering being opposite to one another, the largest diameter of the inner cone being at most as large as the smallest diameter of the outer cone.
- the two nested cones, where the inner cone has the largest diameter and the outer cone has the smallest diameter are connected to each other, preferably integrally connected to each other, for example, by a parallel to the base wall extending annular wall or a A plurality of webs running parallel to the base wall.
- the columns have a substantially constant wall thickness over their entire height. Such columns can be constructed in a particularly simple manner.
- the wall thickness of the columns varies from its base end towards its tip end, preferably increases from its base end to its tip end.
- the resistance of a column to forces acting on it in a vertical direction for a given column material depends on the cross-sectional area of the column at that height position where the column has the lowest cross-sectional area. For a conically tapered column, this is the tip end of the column. Therefore, the wall thickness of the column may be varied, for example decreasing from its tip end to its base end, such that the cross-sectional area at no height position of the column is smaller than the cross-sectional area at the tip end of the column.
- At least one reinforcing rib on the outer surface and / or the inner surface of at least one column, wherein the radial height of the at least one reinforcing rib can advantageously vary from the base end to the tip end of the column, preferably increasing from the base end towards the tip end can.

- the thickness dimension and the length dimension extend in the extension plane of the base wall, while the width dimension is orthogonal to this plane.
- the base wall has a substantially square base area.
- the base surface of the base wall can also have a different shape, for example a rectangular shape, in particular a rectangular shape with a surface composed of two square partial surfaces. But it is also a triangular shape, a trapezoidal shape or a honeycomb shape conceivable, just to name a few more examples.
- the edge length of the base wall in the longitudinal direction or / and in the width direction is less than 90 cm, preferably 80 cm ⁇ 1 cm.

- the trench unit composed of two such trench sub-units has the same height as the conventional trench unit.
- two rig members are needed, i. four trench sub-units to represent the same height.
- the height of three trench units according to the invention corresponds to the height of two conventional trench units.
- the plurality of columns can be arranged distributed in any arrangement over the base surface of the base wall, as long as It is ensured that the requirements imposed on the trench unit, in particular with regard to the vertical loading capacity, are met.
- the columns may be arranged in a grid having a plurality of rows of columns and a plurality of column columns, each column being associated with a column row and column column, and wherein the spacing of at least one pair of adjacent column rows and / or column columns is greater than the spacing between other adjacent columns or column columns.
- the gap between pairs of adjacent rows of columns and / or column columns can be used as an inspection passage, can be introduced by the inspection device in the trench, such as a mobile camera for visual inspection of the status of the trench or a high-pressure cleaning lance for cleaning the trench, which consists of one or more Nozzles expels cleaning water under pressure into the trench.

- the Rigolenunterüen be mounted only on the site to trench units, and it must be assumed that this work is carried out by trained auxiliary staff, it is advantageous if any possibilities for assembly errors are ruled out in advance artificially. In the present case, it is therefore particularly advantageous if the assembly person does not need to pay attention to the orientation of the trench units during assembly.
- the trench sub-unit has an inspection passage in both main directions. For example, the distance of the second column from the third column of each column row or column column of the 4x4 grid can be made larger than the distance of the first column from the second column of each row of columns or / and the distance of the third column from the fourth column each row of columns or columns.

But also completely different surface shapes are conceivable, for example, a star-shaped base surface shape.
- At least one column may also have a cross-shaped cross-section, the outline of the cross-shaped cross-section being designed to have the following features: First, it runs partly on the outline of a square whose side edges are parallel to the side edges of the base wall and partly within the outline of this square but not outside the outline of this square.

- this portion of the outline of the cross-shaped cross section is preferably shorter than the connecting line. Due to this configuration of the column cross-section, the openings of the columns on the surface of the base wall facing away from the columns need not be closed by means of separate cover elements, in order to enable a substantially safe walk-in of trench units already laid by the installation personnel.
- the "indentations" of the outline of the cross-shaped cross-section in the area of the corners of the notional square used for the above outline outline shorten the free lengths of the column cross-sectional area such that they no longer represent tripping hazards for the installation personnel's feet
- the imaginary square has a side length of at most 12 cm, preferably at most 11 cm, more preferably at most 10 cm, and "indentations" in the area of the corners of the notional square corresponding to the above features increase the circumferential length and thus the material consumption not compared to a column whose cross-section corresponds to the notional square, but rather result in a shorter and thus less material-consuming circumferential length.

- the surface facing away from the columns surface of the base wall is formed so that two in the height direction to each other inversely oriented and identically formed trench sub-units are immovably connected to each other in the horizontal direction.
- This can be realized, for example, in that the surface of the base wall facing away from the pillars is formed with at least one projection and at least one recess such that two vertically constructed inversely aligned and identically formed railing subassemblies can be arranged in an interlocking manner in a horizontal direction.
- the surface facing away from the columns surface of the base wall is formed so that two in the height direction to each other inversely oriented and identically formed trench sub-units by means of at least one connecting element in the horizontal direction positively connected to one another.
- the positive connection in the horizontal direction in both cases does not exclude that the connection is also positive in the vertical direction, that is, the trench sub-units can be latched together, for example.
- the trench unit comprises two trench sub-units which are arranged with the tip ends of their columns facing each other, and are preferably connected to one another at mutually associated tip ends of columns belonging to different trench sub-units.
- the base wall of one trench sub-unit forms the bottom wall of the trench unit, while the base wall of the other trench sub-unit forms the top wall of the trench unit.
- an intermediate element preferably plate-shaped, be arranged between the two trench sub-units, which interconnects the tip ends of the columns of both trench sub-units.
- This intermediate element is preferably arranged halfway between the two base walls of the trench sub-units, with the result that the free support length of the column pairs of mutually associated columns is halved.
- the intermediate member interconnects not only the tip ends of the columns of a pair of columns, each of which belongs to a different trench subunit, but also the tip ends of one and the same trench subassembly, any forces introduced laterally into one of the columns, such as lateral earth forces, Not to be taken up by this column alone, but they can be forwarded via the intermediate element also to the other pillars of the trench unit or to the opposite side of the trench. This results in a more stable overall

- the intermediate plate 14 serves to connect the two trench sub-units 12 of the trench unit 10 (see FIG. 1).

- the common bottom surface 14c of the two recesses 30 are substantially in the form of tubular projections 32 in the recesses 30, which in the illustrated embodiment have two locking elements 34 which is intended to cooperate with a preferably circumferential undercut of the tip end 20b of the columns 20.
- FIG. 4 is not compatible with the stabilizing crosspiece with the latching according to FIGS. 7 and 8. If, however, the protrusions 32 were omitted and only the locking elements 34 provided, it being possible to increase, for example double, their number, then one could also combine the embodiment variant of FIG. 4 with the stabilizing web cross with an intermediate plate 14, which has recesses 30 according to FIGS. 7 and 8.

In this way results in a relation to shifts in the horizontal direction stable composite.
- the side closure element 40 is laterally supported exclusively on the base walls 16 of the two trench sub-units 12 and the intermediate plate 14, but not on the edge and corner columns 18. In this way it can be prevented that horizontal forces coming from the soil surrounding the trench be introduced via the side finisher 40 in the trench unit 10, are introduced via the columns 18 in the trench unit 10. This can be further improved by a lateral projection x of the base walls 16 (see FIG. 11) over the base end 18a of the columns 18, as will be explained in more detail below for the embodiment variants of FIGS. 11 to 13.

While the vertical forces are transmitted from the columns 18, 20, horizontal forces are transmitted from the base walls 16 and the intermediate plates 14. In this way, an overload of the columns 18, 20 can be avoided by the simultaneous action of horizontal and vertical forces. This has an advantageous effect on the stability of the trench.

- the side closure elements 40 serve in particular as support bodies for a geotextile, from which such riggings are usually enveloped in order to prevent the penetration of soil into the interior of the trench in the operating state in which the trench is arranged in the ground.
- the lattice structure of the side termination elements 40 what has been previously said for the lattice structure of the bottom walls 16 applies in an identical manner.
- latching elements 42 may be provided which serve the attachment of the side closure elements 40 on the base wall 16 of the trench sub-units 12 and, if desired, also on the intermediate plate 14.

- FIGS. 17 to 21 show a third embodiment of a trench unit according to the invention, which essentially corresponds to the embodiment according to FIG. Therefore, in the figures 17 to 21 analogous parts are provided with the same reference numerals as in Figure 1, but increased by the number 500.
- the trench unit 510 according to figures 17 to 21 will be described below only in so far as they are different from the trench unit 10 differs according to Figure 1, whose description is hereby expressly referred to otherwise.
- a first difference between the trench unit 510 and the trench sub-units 512 of which it is composed and the trench unit 10 and its trench sub-units 12 is that their columns 518 are arranged in a pure 4x4 grid. However, the columns 518 of both the second and third column rows 522 and the second and third column columns 523 are spaced apart from each other by a greater distance than the first column row from the second column row, the third column row from the fourth column row, the first column column from the second column column and the third column column from the fourth column column (see also Figure 11). In this way, not only an inspection passage 524 is formed between the two middle column rows 522, but also an inspection passage 524 'between the two middle column columns 523.
- the grid structure 516a of the base wall 516 of the trench sub-units 512 is replaced by a Support surface 516b for an inspection device 554 (see Figures 19 and 20) covered, for example, a driving surface for wheel-guided inspection device, such as a camera dolly.
- a second difference is that the base wall 516 of the trench sub-units 512 has an exaggerated peripheral edge 516e.
- the height h 'of the peripheral edge 516e (see Fig. 20) on the major part of the circumference of the base wall 516 is greater than the height h of the remainder of the base wall, i. as the distance between the top 516c and the bottom 516d thereof.
- the peripheral edge 516e Only in the area of the accesses 556 to the support surfaces 516b of the inspection channels 524, 524 'does the peripheral edge 516e have the same height as the remaining base wall 516 (see in particular FIG. 20).
- the reason for the elevation of the peripheral edge is the following:
- the packing density achieved by stacking the trench sub-units 512 is so high that the load-bearing capacity of the trucks commonly used for transport to the construction site is reached before the available loading volume of the trucks has been fully utilized.
- the remaining loading volume utilizes the present embodiment to make the peripheral edge 516e of the base wall 516 higher. With this increase of the peripheral edge 516e, only a slightly increased material consumption is associated.
- the security of the forwarding of horizontal forces from trench unit to trench unit in the installed state of the trench units can be increased, and on the other hand the lower access areas 556 can be used as grips for gripping and separating the trench sub-units 512 from the transport stack (see FIG. 16) ,
- the grid webs 516a which adjoin the peripheral edge 516, obliquely drop from the peripheral edge 516e to the remaining base wall 516, as shown particularly in FIG. It should be noted in relation to FIG. 17 that the fact that the Columns 518 at the two front edges of the base wall 516 from the peripheral edge 516 have no distance, as shown in FIG 18, only due to a perspective distortion.
- a third difference is that the pillars 518 have neither a square nor a circular cross section, but a cross-shaped cross-section.
- the outline 560 (shown in solid lines in FIG. 21) of the cross-shaped cross-section has the following properties:
- a portion 560a of the cross-section cross-section 560 extends between a first outline point 562b of the square 562 and a second outline point 562c of the square 562 within the outline of the square 562.
