Description

The invention relates to a slope stone for the construction of slope stabilizers, consisting of a front wall, a rear wall and two side walls that abut in edges.

Such elements are known, the two Swiss patents 612 233 and 612 238 disclosing two elements which are similar to one another and which, in addition to the square or rectangular side walls, have a connecting wall which supports two opposite side walls and which serves to thinner the side walls under the same load conditions without risking breaking the element.

Such an intermediate wall has the advantage of saving material and weight, but it complicates both the production of the elements and their filling by means of soil, since it requires the filling of two channels and also the size of the plants used to consolidate the soil in half limits what is possible with an element with an empty interior.

The invention has for its object to provide a slope stone which avoids the disadvantages of the prior art and is easy and inexpensive to manufacture.

According to the invention, this object is achieved by

that in the case of an embankment stone of the type mentioned at the beginning, the inner corner areas are reinforced. This can make the partition walls unnecessary.

The invention is explained in more detail with the aid of the drawing, in which FIG. 1 shows a slope stone according to the invention in section, FIG. 2 shows a front view and FIG. 3 shows the same slope stone in plan view.

Figures 4 and 5 show a slope protection by means of the embankment stones according to the invention in section and in front view, Figure 6 in plan view.

In FIG. 1, an embankment block 1 is shown in section, reference number 2 denoting the front wall and 3 the rear wall. The front wall 2 is higher on the top of the embankment stone than the wall 3, so that this forms a step 4, which, as shown in more detail in FIG. 3 in plan view, extends over a part of the front and rear walls 2 and 3 connecting Side walls 11 extends, with extensions 5 being formed. This step 4 serves to achieve a secure step-like structure when stacking several embankment stones by abutting the lower part of the front wall 2 of the upper embankment stone on the flank 6 of the step 4 of the lower embankment stone, as shown in FIG.

At the lower end, the front wall 2 is reinforced towards the inside and forms a wedge-shaped support 7.

The shape of the support is advantageously chosen so that its width 8 is relatively large, but its thickness 9 is small. It advantageously has the shape of a wedge in cross section.

The advantages of this shape result from the fact that the width 8 of the support determines the angle of repose of the soil between two slope stones arranged obliquely one above the other, a wide support, as shown in FIG. 4, allowing a smaller angle of repose than a narrow support.

In order to achieve a reasonable relationship between the angle of repose and the angle of repose, the width of the support 7 should be greater than the length of the flaps 5 in the direction from the front wall 2 to the rear wall 3.

The thickness 9 of the support should be small due to material and cost reasons, which is not a problem because of the relatively low pressure of the soil, which is arranged above the support, since the cutting height corresponds at most to the height of the front wall 2.

The wedge shape of the cross section of the pad 7 is the cheapest for manufacturing reasons.

FIG. 2 shows an embankment stone from FIG. 1 from the front, it being evident that the step 4 of the front wall 2 extends over its entire width. The contours of the side walls 11 lying behind are drawn in dashed lines.

FIG. 3 shows a top view of the embankment stone, the reinforcement 37 according to the invention of the inner corners 30 between the walls 2, 3 and 11 being recognizable. The reinforcement 37 of the inner corners 30 by means of concrete has the purpose of increasing the breaking strength of the embankment stone, which is lower at the corners than on the walls, and can be done by means of concrete alone, but advantageously also by means of a corresponding reinforcement, which is located around the inner corners extends around.

The step 4 of the front wall 2 is drawn over the two inner corners 30 between the front wall 2 and the side walls 11 and thereby forms the two tabs 5.

The support 7 also extends from the top across the entire width of the front wall and thus creates a sub-space closed at the bottom for receiving soil for weighting.

FIG. 4 shows the nesting of several embankment stones, the embankment stones 40 and 42 lying in the same plane parallel to the drawing plane, and the embankment stones 41 and 43 being displaced perpendicular to the drawing plane by slightly less than the depth of an embankment stone. The straight line 44 designates the slope angle, and the straight lines 45 and 46 correspond to the angle of repose of the soil between two slope stones lying in the same plane.

In the case of the embankment stone 43, the width of the support 7 is varied by a narrower support T drawn in dashed lines, it being immediately apparent that the wider support 7 is a

smaller angle of repose 46 corresponds to the narrow support 7 ', which gives the angle of repose 45.

It can also be seen from FIG. 4 how the embankment stones are blocked horizontally with respect to one another by means of the steps 4. The vertical safety is due to the weight of the elements and the weight of the soil filling them.

FIG. 5 shows the stacking of the embankment stones from the front, the lateral displacement of every second embankment stone becoming clear. Shrubs 53 and other plants with long and firm roots are planted in the beds 50 between two embankment stones 51, 52 lying directly one above the other in order to ensure that the soil is solidified.

The arrangement of the individual embankment stones takes place in such a way that the side walls 11, 11 'come to rest on each other, e.g. Support the lower corners of the front side wall of the slope stone 58 against the flanks s (reference number 6 in FIG. 1) from the two steps 4, 4 'of the two slope stones 61, 62 lying diagonally below.

FIG. 6 shows the stacking of the embankment stones in a top view, the step-like displacement to the rear of the upper embankment stones 70 being recognizable. The support of an upper slope stone 70 against the flanks 6, 6 'of the two steps 4, 4' of two slope stones 75, 76 located directly below the slope stone 70 is also visible.
