The installation of the Maccaferri Terramesh system, reinforced soil structure with gabion face has started at bridge 206-00 on the motorway D1, Hricovske Podhradie – Lietavska Lucka.
Project is build by Yellow FIDIC book, which allows to contractor to optimize the technical solution of structures
In this case contractor with assistance of Maccaferri team, has shortened the length of bridge about one section, where replace one section of bridge with reinforced soil structure with gabion face – Terramesh system. Because the wall was founded on soils with very low bearing capacity (poor wet clays), practicaly in swamp, there was necessary to not only improve the deformation modulus with two layers of MacGrid EG40S geogrids with stone, but because of height of structure and loadings applied, but due the heoght of embankment also assure the global stability with basal reinforcement with high performing geogrids Paragrid 200/05.
A use of Terramesh system face units from double twisted steel wire mesh, type 8×10, 2,7/3,7mm with PVC coating; helped to respect the land dedicated for construction of highway. On the top of wall from Terramesh system, would be founded concrete bridge abutment on piles. Due to height of structure reaching up to 10m, the fascia Terramesh units are extended by ParaGrid polymer geogrid with lengths up to 12m. The contractor decided for Maccaferri, because we offered complex solution combining mix of economic and stability performance.
