Abstract

"CAPA DE ESTACA". Uma capa de estaca compreende uma folha flexível (2) na forma de paralelogramo com membros tesos mas não completamente rígidos (3) ao longo de um par de bordas opostas salientes do lado da folha a ficar exposto. Este lado possui anda abas ou nervuras flexíveis (4) paralelas a esses membros. Quando enrolados em volta de uma estaca (1), os membros (3) são apertados e presos uns aos outros, forçando esses membros a uma configuração helicoidal, similar àquela adotada pelas nervuras ou abas (4). A água que escoa além da estaca é desviada para a direção longitudinal da estaca, reduzindo a tendência a vibração induzida por vórtice."PILE COVER". A pile cap comprises a flexible sheet (2) in the form of a parallelogram with stiff but not completely rigid members (3) along a pair of opposite edges protruding from the side of the sheet to be exposed. This side has flexible flaps or ribs (4) parallel to these members. When wound around a pile (1), the members (3) are tightened and secured to each other, forcing these members into a helical configuration, similar to that adopted by the ribs or flaps (4). Water draining past the pile is diverted to the pile's longitudinal direction, reducing the tendency to vortex-induced vibration.
