The construction relief, particularly of bridge abutments, is carried out through forming of the earth reinforced with geosynthetic material behind the monolithic structure of the object. Relief can be applied on the back walls, as well as the wing walls of newly built or already existing bridge abutments.
After building the block from the reinforced earth, we receive an empty space between the block and the monolithic wall of the abutment. It reduces the pressure of priming ground on the wall to “0” (zero). Horizontal force acting in a traditional abutments on the monolithic construction is taken over by geosynthetic materials forming a block of reinforced earth.
Additionally, due to reduction of the sizes of monolithic structures (walls, wings) as a result of decreased forces in the cross-sections, also there is a reduction of influence occurring on the intermediate foundations of the abutments. This results in the possibility of optimizing the intermediate foundation (eg. reducing the number of piles and / or diameters), which brings relatively large savings compared to conventional construction technologies.
