Ground anchor
Franki Geotechnics B
an axial element is placed in a seal and borehole in the ground by injection. By friction the load is transmitted towards the ground. The ties are pressurized, the nails are passive.
Characteristics:
strands of prestressed or bars of steel or lost borehole tubes: section and characteristic of steel are determined by the fourniceurs (EP Diwidag, Ischebeck, Fressinet)
provisional and final ties (different protector from corrosion)
gravitating injection, IGU (injection total to unitair) and IRS (injection repetitive and selective)
possibility of exécutioncomplètement dismountable
give the responsability max to be taken again is determined by the characteristic of ground and the type of injection (gravitating, IGU, IRS)
Scope of application:
reserve of pressure earth and water, macadam binding
resumption of the tractive efforts on the constructions requested by the water uplift
