Abstract

A method for securing vertical embankments has retaining boards (8) pressed onto the embankment by earth anchors (4). For tall embankments two or more boards are set at different levels. The system is enhanced by securing wire baskets to the boards to hold decorative infill.

Description

The The invention relates to a method for securing terrain jumps.

In many cases this support walls are built, making sure that the retaining walls at the back can absorb the upcoming earth pressure.

Gravity walls, which satisfy these static requirements must be relatively wide. They are therefore expensive to manufacture and need lots of space.

Instead it is also possible to absorb the earth pressure by Erdnorkeln. This will be on the front surface of the terrain jump arranged load distribution plates held by ground anchors. Of the Earth pressure is due to vaulting effect supported on the load distribution plates. The aesthetic appearance a secured by load distribution plates terrain jump however, in many cases not given the requirements, so that retaining walls given preference becomes.

retaining walls can be executed as an angle support walls, being at the foot of the retaining wall a rigidly connected angle leg extends to the rear, which is determined by the weight of the ground mass resting thereon. For this are significant earthmoving work required.

Gravity walls can also be built from gabions. For static reasons but at higher Terrain jumps the required width of such gabion heavyweight walls relatively large, so that the cost and space requirements increase significantly with increasing altitude of the terrain jump.

task It is therefore an object of the invention to provide methods for securing terrain jumps create that even at higher altitudes Terrain jump with low space requirement executed can and can at the same time an aesthetic offer appealing view.

• b) dass vor den Lastverteilungsplatten eine Steinwand aus mit Steinen gefüllten Drahtkörben errichtet wird und
• c) dass die Lastverteilungsplatten und/oder die aus den Lastverteilungsplatten herausragenden Enden von Erdankern der Erdvernagelung jeweils mit der Rückwand des davor befindlichen Drahtkorbs verbunden werden.

According to a further variant of the method according to the invention,

• a) arranged on the front surface of the terrain jump at a distance to each other load distribution plates and set by Erdnorkelung,
• b) that before the load distribution plates a stone wall made of stone filled wire baskets is built and
• c) that the load distribution plates and / or protruding from the load distribution plates ends of Erdankern Erdnorkelung are each connected to the rear wall of the front wire basket.

in this connection can advantageously still be provided that a between the backs of the wire baskets and the front surface of the terrain jump resulting cavity is filled with stone material or the like.

The pressure and possibly traffic loads are recorded via the Erdnorkelung and the load distribution plates, which forms a vaulting effect in the earth wall of the terrain jump. The wire baskets in the filled state have a relatively narrow cross-section, which is connected to the Erdnorkelung and therefore despite their narrow design can be arranged over greater heights. The filled wire baskets on the one hand form a veneer of the terrain jump, whereby the elements of Erdnorkelung are no longer visible. On the other hand, the narrow wire baskets are water permeable, so that emerge from the front surface of the terrain jump the water is derived without pressure build-up. Finally, allow the joints of the stone filling the wire ball baskets a greening of the thus secured terrain jump.

According to one preferred embodiment of Invention is provided that after the introduction and compression of ground anchors for Earth netting a geotextile mat on the front face of the terrain jump created and followed by attached load distribution plates is attached.

Further advantageous embodiments of the inventive concept are the subject further dependent claims.

embodiments the inventive method get closer explained and shown in the drawing. Show:

1 - 5 in each case in a vertical section through a terrain jump to be secured successive stages in an embodiment of the method according to the invention and

6 and 7 each in a section corresponding to the 5 modified versions of the method.

The terrain jump shown in each case in vertical section has an example vertical front surface 1 on, at the upper edge of the terrain top 2 followed. At the foot of the terrain jump is a frost-proof foundation 3 executed, for example, a strip foundation.

As in 1 shown are in the front surface 1 possibly staggered according to statistics in several rows Ground anchors (pegs or piles) 4 introduced slightly sloping inward, which are installed in a known manner by compression. A geotextile mat 5 is after the introduction and pressing of the ground anchor 4 on the front surface 1 created the terrain jump. The upper edge 5a the geotextile mat 5 gets on the terrain top 2 turned over and there, for example, with nails 6 attached. The bottom edge 5b the geotextile mat 5 lies on the top of the foundation 3 ,

In the illustrated embodiment, the top of the foundation 3 sloping down, being at the bottom of the geotextile mat 5 a drainage pipe 7 is inserted for drainage.

Then, each on the front surface 1 overhanging end 4a every ground anchor 4 a statically dimensioned load distribution plate 8th through an anchor plate and screw connection 9 appropriate. The spaced apart load distribution plates 8th Under the formation of a vaulting effect in the ground, they absorb the impending earth pressure and carry it over the ground anchors 4 from. At the same time, the load distribution plates 8th the geotextile mat 5 fastened without displacement.

Then - starting with the bottom row of load distribution plates 8th - in front of the front surface 1 and the load distribution plates 8th wire baskets 10 arranged ( 2 ), with the back 10a every wire basket 10 to the contour of the respective load distribution plate located there 8th is adjusted. The wire baskets 10 can be mounted in the size you want, with the back wall 10a in each case only inwardly deformed, where there is a load distribution plate 8th located. The back wall 10a every wire basket 10 is used at the Erdnorkelung and / or the load distribution plates 8th attached.

Then the wire baskets, which are still open at the top 10 the bottom row from above with stones 11 filled ( 3 ) and closed. If, as in the illustrated embodiment, multiple rows of wire baskets 10 are provided, then these wire baskets 10 arranged one above the other starting with the bottom row. This will be the wire baskets 10 each row filled before the wire baskets 10 the next higher row are attached and filled.

In 4 is shown after fixing and filling the wire baskets 10 the bottom row the wire baskets 10 the upper row attached and also from above with stones 11 filled and closed. The final state then reached is in 5 shown.

The bottom row of filled baskets 10 is on the foundation 3 founded frost-free. The drainage takes place in the lower area of the lowest row of filled wire baskets 10 and is trained according to local conditions. Here, a longitudinal or transverse drainage and connection to an existing drainage system or infiltration may be provided. Because of the constructive connection of the filled wire baskets with Erdnorkagelung the wire baskets can be made relatively narrow even at high terrain jumps. The material and space requirements are correspondingly low.

Notwithstanding that in the 1 - 5 illustrated embodiment, the attachment of the wire baskets can also be done by prior to attaching the load distribution plates 8th and possibly after placing the geotextile mat 5 first the back walls 10a the wire baskets 10 on the front surface 1 protruding ends of the ground anchors 4 be attached. Then the load distribution plates 8th fitted and in the manner already described by means of the screw 9 attached. Then the wire baskets 10 with stones 11 filled and closed.

6 shows in a section corresponding to the 5 a terrain jump with a featured stone wall. For the same parts here are the same reference numerals as in 5 used.

As with the previously described method are on the front surface 1 of the terrain jump in the distance to each other load distribution plates 8th arranged and by ground anchors 4 determined by means of Erdnorkelung. In front of these load distribution plates 8th becomes a stone wall with stones 11 filled wire baskets 10 built. The load distribution plates 8th or preferably from the load distribution plates 8th outstanding ends 4a the ground anchor 4 the Erdnorkelung are each with the back wall 10a the wire basket in front of it 10 connected. These can each be at the ends 4a provided at the nail head of Erdnorkung bolted metal eyelets, where the wire baskets 10 Tension-resistant from bottom to top are attached corrosion-free.

The grid of the ground anchors 4 Erdnorkung depends on the dimensions of the available wire baskets 10 ; You can between the wire baskets 10 and the front surface 1 of the terrain jump cavities 12 arise.

As in the example according to 7 shown are those with stones 11 filled wire baskets 10 arranged so that they form a "scarf" before Erdnorkelung, so that the cavities 12 with stone material 13 od. Like. Can be filled.
