Abstract
Abstract The invention relates to a pile or foundation member particularly adapted for use in offshore or similar applications, wherein a hostile environment or a severe corrosion problem is a pertinent factor. The pile comprises an elongated member formed essentially of a series of reinforced concrete pile sections. A metallic cap carried at each pile section end is adapted to engage and be fixed to a corresponding cap on the next succeeding pile end whereby to define a rigid interface connection between the two. The metal joint thus formed between the concrete sections is then isolated from its surroundings by means of an encapsulating or enclosing barrier formed on the pile whereby to be protected from the environment.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
168 words
A longitudinally extendable foundation pile for use in the presence of an environment hostile to metallic structures, and adapted to be embedded into a substratum which comprises; a nonmetallic pile element formed of a plurality of longitudinally positioned elongated pile sections having oPpositely disposed end faces and being connected one to the other at said end faces, an interface connector disposed intermediate adjacent end faces of said respective pile sections and including, a pair of detachably interlocked connector members, at least one locking key mutually engaging said pair of connector members to maintain them in rigid interlocked relationship, and means forming an enveloping barrier about said foundation pile whereby to enclose said interface connector from exposure to the surrounding hostile environment, and alignment guide means carried at the end of one of said pile sections and adapted to slidably engage a surface of an adjacent pile segment, whereby to guide the respective sections together when the latter are brought into alignment whereby to engage said interface connector members.
Claim 2
Dependent Claim
168 words
A longitudinally extendable foundation pile for use in the presence of an environment hostile to metallic structures, and adapted to be embedded into a substratum which comprises; a nonmetallic pile element formed of a plurality of longitudinally positioned elongated pile sections having oPpositely disposed end faces and being connected one to the other at said end faces, an interface connector disposed intermediate adjacent end faces of said respective pile sections and including, a pair of detachably interlocked connector members, at least one locking key mutually engaging said pair of connector members to maintain them in rigid interlocked relationship, and means forming an enveloping barrier about said foundation pile whereby to enclose said interface connector from exposure to the surrounding hostile environment, and alignment guide means carried at the end of one of said pile sections and adapted to slidably engage a surface of an adjacent pile segment, whereby to guide the respective sections together when the latter are brought into alignment whereby to engage said interface connector members.
Claim 3
Dependent Claim
42 words
In an apparatus as defined in claim 1, including; a confining belt operably carried on a pile section and being slidably adjustable to circumferentially enclose said interface connector subsequent to the latter becoming interlocked and prior to introducing said fluid tight barrier.
Claim 4
Dependent Claim
28 words
In an apparatus as defined in claim 2, wherein a portion of said fluid tight barrier is disposed internally of said pile, and adjacent to said interface connector.
