The drilling has dual function.
The first section –anchor head-, is going to be injected with epoxy concrete or with another reoplastic concrete, studied for it and “MICROGROUT INJECTION ANCHOR” of rapid hardening, able to transfer the requirements of metal fixing to the pre-existent foundations (in walls), to a sufficient length to transfer the charges of the building over the minipoles.
The second section of the “minipalo GEO-SYSTEM®” is inserted in the field over a certain length depending on the limit charges established in the project and successively the polyurethane resin of double composition is injected with an expansion rate of 5/8 times the initial volume and the resistance of the compression of 30n/mmq or with the expansive concrete “Geo-Xp”, with resistance to compression in free expansion of 80-100% of its initial volume.
The choice of the injection product change depending on the type of field to consolidate, and in any case, both enable to transfer the fixing needs of the terrain, as well as to consolidate the terrain, thanks to the resistance, penetration and expansion of the materials used.
The “minipali GEO-SYSTEM®” may work in an autonomous way or connected, and even with steel platen of various shapes and dimensions (straight, with angles, etc) depending on the need, attached to the foundations with fasteners that vary depending on the support.
The coupling –slab- “minipalo GEO-SYSTEM®” is secured with steel bolts of high resistance, in order to create a cordoning over the foundation of the affected area for the intervention, avoiding eventually distinct landslide. It is possible to check each “minipalo GEO-SYSTEM®” before the final connection of the structure through temporary assignment of charges test.
