Cuttings / rods in metal pipes and metal helical hollow piles / rods on steel pipes or square or circular threaded bar.With injection of cement laitance and with elastic rubber bag or special propeller

摘要

The innovation proposed describes cuttings / rods, metal coil, into sections of hollow steel tubes or bars, square.Consisting of a section guide and eventually a section handler, in steel tubes or bars, square or circular and threaded, both with one or more propellers square,With or without rounded corners or propellers in circular steel plates, with all of the hollow metallic tubes, joined by seams with fitting the bag threaded or amendments.Having holes between the blades, to exit from the layer of cement to be injected, under pressure, through the hollow tubes, thus forming a bulb, for better fixity of the cuttings / rods.To be used in the great majority of soil types in anchoring rods or piles for foundations of Guyed towers or self, for electrical power transmission lines.Telecommunications, foundations of structures and equipments of substation electric energy, foundations of buildings, roofs, bridges, viaducts, lamp posts, fences,Foundations of equipment structure in general, anchors and supports for oil and gas pipelines, supports for pipelines, atirantamentos curtain and slopes among others.
