Retaining Wall with Reinforced Soil

Abstract

The invention is applicable in the field of retaining structures, known as “reinforced soil. More specifically, it refers to a facing element for reinforced soil structures and excavation faces and to a structure for reinforcing slope and excavation faces made with the facing element provided for in the present invention. The facing element for reinforced soil structures and excavation faces provided for in the present invention is made of a natural origin material, composite, biological or synthetic, for example a biopolymer such as polylactic acid 100 percent genuine (PLA) or polylactic acid bonded with other elements (composite PLA), composite with a fibre material containing cellulose, such as WPC wood, or natural wood.

1 . Facing element ( 1 ) for reinforced soil structures, embankments and excavation faces made of a biodegradable material, wherein the material being a composite, biological or synthetic material having natural origin, wherein the facing element ( 1 ) is a grid ( 2 ). 
     
     
         2 . Facing element for reinforced soil structures, embankments and excavation faces according to  claim 1 , in which the biodegradable material is pure polylactic acid or polylactic acid bonded with other elements. 
     
     
         3 . Facing element for reinforced soil structures, embankments and excavation faces according to  claim 1 , in which the biodegradable material is wood. 
     
     
         4 . Facing element for reinforced soil structures, embankments and excavation faces according to  claim 1 , in which the biodegradable material is a fibre composite material containing cellulose. 
     
     
         5 . Facing element for reinforced soil structures, embankments and excavation faces according to  claim 1 , in which the facing element ( 1 ) further includes a second grid ( 3 ) which is smaller in size than the grid ( 2 ), and wherein the grid ( 2 ) and the second grid ( 3 ) being reciprocally hinged in correspondence of a side ( 21 ). 
     
     
         6 . Facing element for reinforced soil structures, embankments and excavation faces according to  claim 1 , in which the facing element ( 1 ) further includes a second grid ( 3 ) , the grid ( 2 ) and the second grid ( 3 ) being reciprocally joined by interlocking elements in correspondence of a side( 21 ). 
     
     
         7 . Facing element for reinforced soil structures, embankments and excavation faces according to  claim 5  , further comprising tightening brackets ( 5 ), said brackets ( 5 ) having a triangular shape and being fastened to the grid ( 2 ) and to the secondary grid ( 3 ) so as to keep the designed inclination of the work planned for the facing element, said brackets ( 5 ) being made of the same natural material as the facing element ( 1 ). 
     
     
         8 . Facing element for reinforced soil structures, embankments and excavation faces according to  claim 5 , further comprising spacer devices having a length suitable for keeping the designed inclination of the facing element ( 1 ). 
     
     
         9 . Structure for reinforced soil, embankments and excavation faces ( 100 ) comprising a facing element ( 101 ) as claimed in  claim 1  and a strengthening net ( 103 ) having a greater width or at least a lateral extension ( 104 ), said elements being reciprocally fastened so as to set up a single reinforcing structure for soil, embankments and excavation faces. 
     
     
         10 . Structure for reinforced soil, embankments and excavation faces ( 100 ) according to  claim 9 , in which the reinforcement element ( 103 ) is a double twisted wire mesh. 
     
     
         11 . Structure for reinforced soil, embankments and excavation faces ( 100 ) according to  claim 9 , in which the reinforcement element ( 103 ) is a geo-synthetic material.
