Description

Retaining wall skeleton

Technical Field

The present utility model relates generally to a system for reinforcing a side slope and, more particularly, to a retaining wall skeleton.

Background

It is known to use metal frames, as well as polymeric geogrids, to strengthen soil layers in the construction of retaining walls. U.S. patent No.6,595,726 (simply the' 726 patent) discloses a structure of a geogrid reinforced earth retaining wall comprising welded metal frames.

The' 726 patent discloses a metal shelf having a vertical face and a bottom face wherein the horizontally extending portion includes a raised structure defining an aligned opening adjacent the rear edge of the horizontally extending portion. The protrusion structure provides an effective arrangement for securing the geogrid by placing selected geogrid apertures over the protrusions and then inserting relatively long connecting elements through aligned openings of the protrusions to retain the geogrid in the horizontal extension. In addition, a separate strut member is provided to interconnect the top end of the vertical face with the rear end of the horizontally extending portion to form a triangular stretched structure to enhance the overall strength of the metal frame.

However, the solution described in the' 726 patent requires separate connecting elements and separate prop elements, which perform different functions, and the connecting elements need to extend through the entire horizontal extension, for which reason the connecting elements must be long, making the installation of the retaining wall skeleton difficult, wasteful of material and time and effort consuming.

Referring to fig. 1, the retaining wall skeleton includes a metal frame 1 and a fixing rod 2, the metal frame 1 includes a bottom surface 11 and an upright surface 12 extending upward from one side of the bottom surface 11, and the bottom surface 11 intersects with the upright surface 12 at a bottom edge 3. The vertical surface 12 may be perpendicular to the bottom surface 11, or the vertical surface 12 may be slightly inclined toward the rear end of the bottom surface 11. By arranging the pre-inclined vertical surface 12, a certain deformation space can be reserved, so that the whole retaining wall skeleton is kept basically vertical after the vertical surface 12 is deformed under stress.

The retaining wall skeleton may be filled with filler 4, which may be aggregate, soil, crushed stone, concrete, or the like.

The upper part of the upright face 12 remote from the bottom edge 3 has at least one first metal rib 13 which is substantially parallel to the bottom edge 3. In some embodiments, the rear end of the bottom surface 11 remote from the bottom edge 3 has at least one third metal rib 14 substantially parallel to the bottom edge 3. In some embodiments, the bottom surface 11 and the upright surface 12 include a plurality of ribs for reinforcement.

Referring to fig. 2, the rear end of the bottom surface 11 is formed with an n-shaped protrusion 15 for alignment with the opening of the geogrid 5. Although a one-way grille is used in the drawings, a two-way grille, a three-way grille, a six-way grille, or the like may be used as long as the openings at the ends of the grille correspond to the n-shaped protrusion structures 15.

The width W of the metal frame 1 can be adjusted as required. In some embodiments, geogrid 5 can have any width and any length, and can be formed using any well known prior art technique, including braiding, knitting, or a mesh-like structure for securing wires or ribbons to one another. In some embodiments, the width of the geogrid 5 is equal to the width of the metal frame 1. In some embodiments, a plurality of geogrids smaller than the width W of the metal frame 1 can be used to mate with the metal frame 1. In some embodiments, geogrids greater than the width W of the metal frame 1 can be used to mate with multiple metal frames 1.

In some embodiments, the n-shaped protrusion structures 15 are formed by a plurality of parallel metal strips 16 perpendicular to the bottom edge 3. Although the metal strip penetrating through is used in the drawing, the n-shaped projection structure 15 may be formed at the rear end of the bottom surface 11, and the structures of the bottom surface 11 and the other parts of the standing surface 12 are not limited.

With continued reference to fig. 1, the walls 17 of the n-shaped protrusion 15 distal from the rear end are at an acute angle to the bottom surface 11 to better secure the geogrid against stress-stripping. In some embodiments, the acute angle is 45 degrees or less.

In constructing the retaining wall, the metal frame 1 is positioned, as shown in fig. 1, with the vertical face 12 forming a part of the vertical face of the retaining wall and the bottom face 11 extending rearwardly therefrom. The front apertures of the geogrid(s) 5 are then positioned over the n-shaped protrusion 15, secured by the walls 17 of the n-shaped protrusion 15. The fixing bars 2 are then inserted into the n-shaped protruding structures 15 to fix the geogrid 5 as well as to provide tension to the standing surface 12. Aggregate 4, such as soil, is then filled behind the standing surface 12, above the bottom surface 11 and geogrid 5. If desired, an erosion shield of conventional construction may be placed over the bottom surface 11.

Referring to fig. 3, the fixing lever 2 includes a lever body 20, a first end 21 and a second end 22, the first end 21 having a first hook 23 for connection with the first metal bar 13 at the upper portion of the standing surface 12.

The plane of the first hook 23 is substantially perpendicular to the plane of the second hook 24. Referring to fig. 4, the width W1 of the second hook 24 facing the arc apex of the rod 20 and the gap formed between the rod 20 is smaller than or equal to the diameter of the metal strip 16 of the n-shaped protrusion 15, so that the metal strip 16 is not easy to fall out after passing through the gap.

In some embodiments, referring to fig. 5 and 6, the securing lever 2 further includes a cross bar 25 substantially perpendicular to the lever body 20, extending from the distal end of the second hook 24 away from the lever body 20, the cross bar 25 being substantially flush with the second end 22. The end sections 26 of the cross bars 25 are bent towards the first end 21 of the fixation bar 2 to cooperate with the n-shaped protrusion 15 to better limit the displacement of the fixation bar 2. The distance from the end of the crossbar 25 to the rod body 20 is at least three times the distance between adjacent n-shaped protruding structures 15 to better limit the displacement of the fixing rod 2. At the same time, the lateral portion of such length may better limit the displacement of the geogrid 5.

Referring to fig. 7, the second end 22 of the fixing lever 2 further includes a third hook 27 at the opposite side of the second hook 24, the third hook 27 being bent toward the first end 21 so that the fixing lever 2 can be fixed by the n-shaped protrusion structures 15 at both left and right sides.
