Definitions

  • a method of constructing a reinforced earth structure comprising one or more gabions and a reinforced earth structure comprising one or more gabions.
  • the invention relates to a method of constructing a reinforced earth structure and a reinforced earth structure.
  • Reinforced earth structures are also called stabilized earth structures.
  • Reinforced earth structures are earth structures in which the earth has been reinforced using reinforcing elements, e.g. steel or geosynthetic materials.
  • Geosynthetic materials may include geotextiles, geogrids, geonets and geomembranes.
  • Reinforced earth structures are used for such applications as reinforcing unstable slopes and/or are used as bridge ramps, dykes, reinforced slopes, abutments, quays or as parts thereof.
  • Such reinforced earth structures are sometimes provided with gabions.
  • the walls of the reinforced earth structure can be finished with such gabions for various reasons, e.g. for architectonic reasons or for aesthetical or safety considerations.
  • Gabions consist of a gabion of sturdy wire mesh material, for example steel wire mesh, and are filled with rocks or other fill materials.
  • These gabions may get damaged, for example relatively soon after constructing the reinforced earth structure, by movements resulting from the earth subsiding, or at a later time, for example because a vehicle collides with a gabion.
  • An objective of the invention is to reduce the cost and time involved in installing gabions and/or replacing a damaged gabion, and/or the risk of a gabion being damaged and/or to obtain a better look.
  • the method according to the invention is characterized in that an anchoring system is incorporated into the reinforced earth structure, with the anchoring system containing fasteners placed in vertical parallel bands, after which a gabion of a longitudinal shape is installed, with the sides of the gabion being attached to the fasteners of the anchoring system and the gabion then being filled with fill material.
  • unfilled gabions are box-shaped and are placed in front of a reinforced earth structure, after constructing such reinforced earth structure, after which they are secured to the reinforced earth structure, usually by means of steel wires and then filled with rocks. This is highly tmie-consuming. In addition, it is hard or almost impossible to easily replace a gabion once this is in place, and specifically if it is has been placed under another gabion.
  • the invention uses a longitudinally shaped gabion.
  • the ends of the gabion are attached to the fasteners after which the gabion is filled with rocks or another fill material. This saves time. It also facilitates easier maintenance since damaged gabions are easier to replace.
  • the fasteners shall, preferably, also be suitable for enabling the gabion to be attached such that it can be detached again later.
  • the gabion has a curved shape.
  • the curved shape increases the strength of the gabion, lowers the risk and degree of bulging after filling, and enables larger gabions to be used.
  • the fill material may consist of rubble ⁇ quarry stone, lava stone, flint or other material such as, for example, blocks of peat.
  • the shape of the gabion is such that the sides of the gabion display an angle of between 90 and 60 degrees, but preferably of between 88 and 70 degrees with a plane touching the front of the gabion. If the angle is too small, it will be difficult to fill the parts of the gabion near the fasteners.
  • the angle is preferably between 88 and 70 degrees to make the empty gabions easy to pile on top of each other.
  • Adjusting aids are preferably attached to the anchoring means in order to adjust the position of a gabion coupled to an anchoring means.
  • the adjusting aids offer more freedom to determine the positions of the gabions.
  • the positions of the individual gabions can be adjusted and the gabions can be applied accurately.
  • a reinforced earth structure according to the invention contains a number of earth- retaining layers with a flexible casing material and a fill material, and with the outside of the casing material having a border, and anchoring means containing coupling means that have been positioned in vertical parallel bands to couple the anchoring means to a gabion such that they can be detached, as well as a gabion of a longitudinal, curved shape attached to the coupling means.
  • Adjusting means have preferably been attached to the anchoring means.
  • Figure 1 shows a step in the method according to the invention
  • Figure 2 shows a front view of piled layers of earth with anchoring means and fasteners
  • Figure 3 shows a top view of a reinforced earth structure with a gabion
  • Figure 4 shows a perspective view of a reinforced earth structure with a gabion
  • Figures 5 and 6 show a gabion for a reinforced earth structure according to the invention
  • Figure 7 shows a side view of piled gabions
  • Figure 8 shows a top view of a gabion attached to an earth structure
  • Figure 9 shows a top view of an anchor in the earth structure to which a fastener has been secured and to which a gabion has been attached.
  • Figure 1 shows a reinforced earth structure 1 according to the invention, placed near a slope 2, that, in this example, is to be reinforced.
  • a first earth-retaining layer containing a flexible casing material 3 and fill material 4 is applied. This process is repeated several times, thus piling a number of layers of earth on top of each other.
  • Anchoring means 5 are applied while or after piling the layers of earth. They can be applied between or in the layers of earth.
  • Fasteners 6 are attached to the anchoring means 5, in this example in the form of rails.
  • Figure 2 shows a front view.
  • the anchoring means have been applied between the layers of earth and rails have been attached to them.
  • Figures 3 and 4 show top and perspective views of a further step of the method according to the invention.
  • a gabion 7, which has not been filled yet, is attached to the fasteners 6.
  • the ends of the gabion are attached to the fasteners after which the gabion is filled with rocks or another fill material. This saves time and it also facilitates easier maintenance since damaged gabions are easier to replace.
  • the gabion preferably has a longitudinal curved shape. In the context of the invention, this means that the gabion is not flarbut curved >n the sio" effacing away from the layers of earth.
  • the fill material may consist of rubble, quarry stone, lava stone, flint or other material such as, for example, blocks of peat.
  • the gabion may display a rectangular cross-section, but will preferably display a curved shape.
  • the curved shape in preferential embodiments increases the strength of the structure and enables the use of larger gabions.
  • Figures 5 and 6 show some details of a gabion in a preferential embodiment.
  • the width W is somewhere between 1 and 4 metres, the depth D in the centre of the gabion is somewhere between 25 and 60 cm.
  • the shape of the gabion is such that the sides 7a (figure 6) of the gabion display an angle of between 90 and 60 degrees, but preferably of between 88 and 70 degrees with a plane touching the front of the gabion. If the angle is too small, it will be difficult to fill the parts of the gabion near the fasteners.
  • the angle is preferably between 85 and 70 degrees. This makes the empty gabions easy to pile on top of each other as shown in figure 7.
  • the gabions have some flexibility and their sides will move slightly apart when piling them on top each other.
  • the box-shaped gabions have to be constructed either off-site in a box shape and then be moved to their final location.
  • the produced gabions then occupy a lot of space in or on the means of transport. This makes transporting the gabions very inefficient.
  • the alternative is constructing box-shaped gabions from steel mesh panels on site. However, this is very time-consuming and it requires the on-site presence of machines that can cut the gabions from the panels and/or fold them.
  • the advantage of the invention is that the gabions can be piled in an immediately usable form.
  • the gabions can be transported to the reinforced earth structure efficiently and can be installed efficiently and immediately.
  • Figure 8 shows a more detailed view of a gabion 7 with sides 7a.
  • the width W in this example is somewhere between 100 centimetres and 400 centimetres, but preferably between 200 and 300 centimetres.
  • the depth Dl is somewhere between 25 cm and 60 cm, but preferably between 30 and 50 cm.
  • the depth D2 on the sides 7a is somewhere between 5 cm and 20 cm, but preferably between 7 and 13 cm.
  • the sides 7a have been attached to fastening means 6.
  • FIG. 9 shows a cross-section of such a structure.
  • An anchor 10 has been attached in the earth structure.
  • a fastener 5 an anchor rail in this example, has been attached to anchor 10 using a nut 11.
  • a T-head bolt 8 clamps the raised and bent edges of anchor rail 6.
  • T-head bolts 8 may be placed in several locations in the anchor rail 6. The positions of the T-head bolts along the length of the anchor rail can be selected freely.
  • the T-head bolts and the plates contain adjusting aids to adjust the position of a gabion 7 coupled to an anchoring means 10.
  • the nut is preferably tightened using a torque wrench. This enables the force required to move the T-head bolt in the rail to be adjusted. This means that if vertical subsidence of the earth structure occurs and a certain force is exceeded, which force can be adjusted by adjusting the torque wrench, i.e. if a certain subsidence is exceeded, the T-head bolt will move inside the rail, in a vertical direction, i.e. up or down. This enables any subsidence in a vertical direction, for example due to the reinforced earth structure settling or slumping, to be compensated for.
  • the method and earth structure according to the invention offer high security and great flexibility for the design and look of the earth structure. This offers parties such as architects a lot of freedom to achieve their designs. Different types of gabions may be incorporated into a wall of an earth structure.
  • a reinforced earth structure is constructed from several earm-retaining layers. Anchoring elements are applied. Longitudinal gabions are fitted to these anchoring elements by means of fasteners that are positioned in vertical bands. The gabions preferably have a curved shape. After the empty gabions have been put into place, they are filled with fill material. This enables soil subsidence to be compensated for.
  • the fasteners including the rails, may have been sunk into the reinforced earth structure, as shown in the schematic drawing in figure 9, or they may protrude from the pile of layers of earth, as shown in the schematic drawings in figures 3 and 4. If the rails protrude, the gabions may be placed between the rails such that there is a certain clamping effect.

Abstract

La présente invention concerne une structure en terre armée composée de plusieurs couches retenant la terre. Des éléments d'ancrage sont appliqués. Des gabions métalliques longitudinaux (7) sont prévus au niveau de ces éléments d'ancrage (10) au moyen d'éléments de fixation (6) qui sont positionnés dans des bandes verticales. Les gabions métalliques présentent, de préférence, une forme incurvée. Une fois les gabions métalliques vides mis en place, ils sont remplis d'un matériau de remplissage. Cela permet de compenser l'affaissement du sol.
