CONTROL PILES WITH DEFORMABLE ELEMENT FOR LAYING THE FOUNDATION, RE-LAYING THE FOUNDATION AND/OR RE-LEVELLING A BUILDING AND PRESERVE THEM ACCORDING TO THE ORIGINAL DESIGN THEREOF.

摘要

The present invention refers to a control pile with deformable elements for laying a foundation, re-laying a foundation and/or re-levelling buildings and preserve them according to the original design thereof, which includes a reinforced concrete die with a ring through which freely passes a pile, and metallic anchors embedded into said die for being fastened to the working head screws; the concrete dies are anchored to the original foundation of the building. The pilot is made of concrete, steel or mixed, and improved in the shaft thereof with gorges and rough surfaces, also including a rod built in sections attached by connectors of high resistance arranged in the centre of the pile. The pile is connected by means of deformable elements to a metallic bridge of the rectangular or triangular type by means of steel screws and nuts. The weight of the building is transmitted by said deformable element of copolymerised elastomer resins to the pile and then to deep or resistant layers of t he ground. The deformable element is able to absorb in the same magnitude and speed the downward motion of the building caused by the subsidence, thus it must be periodically replaced; and for the re-levelling of those buildings that present a tilting higher or equal to the admissible values established by the standards, a method being implemented for assigning and transmitting in a variable manner loads by means of a hydraulic cylinder located between the working head and an additional ancillary element for exerting a thrust over the control piles in the zones of higher subsidence of the building, thus provoking a pair-force in the opposite zone which presents a lower subsidence or uplift area, by slowly descending the building by means of pile controls, so as to be re-levelled and achieve the desired verticality in the construction; the operation is assisted by a sub excavation method for reducing the supporting area of the land in the lifted part, where the maintenance thereof requ ires the periodic re-assigning of loads, substituting the deformable element of copolymerised elastomer resins when reaches the deformation range thereof resulting from the behaviour of the building in the interaction with the ground and the regional subsidence. The recovery of the building verticality requires a structural approval, which establishes that it complies with the safety specifications indicated in the Construction Guidelines of the Federal District and the Complementary Technical Standards. This method is used without evacuating the building; the residents may develop their daily activities, without perceiving the motion of the building, and with the required safety and reliability.
