<p>Disposition introduced in a circular vertical drain or in a regular polygonal vertical drain, particularly of a drain in the shape of a pipe with particular geometric characteristics, to be used preferential in embankments constructed on soft lands, with the objective to promote the acceleration of the process of consolidation of the mentioned soft land layers. The model consists in a circular vertical drain (1) confectioned in plastic material, which is lodged inside the mandrill (2), in dimensional relation with the external diameter (3) and internal diameter; the drain (1) properly said establishes with the mandrill (2) a predetermined dimensional relation; the vertical drain (1), preferentially a diameter of 3 cm, can be of circular or regular polygonal section; and the plate of steel (foil) (9), of circular configuration, preferentially in steel sheet cut in stamping, it has a changeable thickness in the standards of use, being that the central area (10) of this foil (9) has the diameter (11) compatible with the vertical drain (1) and it is disposed in the bottom of the mandrill (2), of concentrically way and according to area of diameter (11) compatible with the vertical drain.</p> |
