Patent ID: 7517174

Claim:
A molded pile comprising: (a) an elongated body having an upper end and a lower end, and comprising, (i) a first exterior elongated plate, (ii) a second exterior elongated plate, said first exterior elongated plate and second exterior elongated plate being spaced apart and being substantially opposed from each other, and (iii) a plurality of internal ribs interposed between said first exterior elongated plate and said second exterior elongated plate, said plurality of internal ribs defining at least one elongated passage, and said plurality of internal ribs together defining a plurality of apertures, wherein said first exterior elongated plate, said second exterior elongated exterior plate and said plurality of internal ribs are each independently fabricated from a plastic material and are substantially continuous with each other, and said elongated body is a substantially unitary elongated body; and (b) an elongated tube residing within said elongated passage, said elongated tube having an upper opening and a lower opening each being in fluid communication with an elongated hollow interior of said elongated tube, said elongated tube providing fluid communication between said upper end and said lower end of said elongated body, and being adapted to provide for passage of a fluid at elevated pressure through said elongated hollow interior thereof, wherein passage of said fluid at elevated pressure through said elongated hollow interior of said elongated tube fluidizes a penetrable material into which a lower portion of said elongated body of said molded pile is driven, thereby forming a fluidized penetrable material, and said apertures of said lower portion defined by said plurality of internal ribs being dimensioned to receive fluidized penetrable material therein, thereby anchoring said lower portion of said elongated body within said penetrable material.
