Abstract

Abstract A method of forming an underground pipeline comprising depositing an inner component section of the pipeline on a pipe-laying apparatus and at least partially supporting the inner component section on the apparatus. The inner component section is forced from the apparatus onto an independent support, and the apparatus is advanced to receive another inner component section. After the inner component sections have been transferred to the independent supports, a formable outer component is provided at least part way around and beneath such inner component sections to form the pipeline.

Claim 8
Independent Claim 217 words
A method of forming a pipeline of the type which is at least partially underground and which includes, at least during construction of the pipeline, a plurality of inner component sections at least partially enclosed by a formable outer component, said method comprising: providing an apparatus for at least assisting in installing the inner component sections with the apparatus being on a surface which is to support the pipeline; repeatedly and sequentially depositing inner component sections on at least a portion of the apparatus; at least partially supporting on the apparatus each of the inner component sections which is deposited on the apparatus; providing inner component section supporting means on said surface; forcing each of the inner component sections supported on the apparatus from the apparatus to the supporting means to thereby transfer at least some of the support of the inner component sections to the inner component section supporting means and to place the inner component sections in end-to-end relationship; placing the formable outer component at least beneath the inner component sections supported by the inner component section supporting means to thereby provide additional support for the inner component sections; and initiating said step of placing for a plurality of said outer component sections subsequent to said step of forcing said plurality of inner component sections.
Claim 9
Independent Claim 217 words
A method of forming a pipeline of the type which is at least partially underground and which includes, at least during construction of the pipeline, a plurality of inner component sections at least partially enclosed by a formable outer component, said method comprising: providing an apparatus for at least assisting in installing the inner component sections with the apparatus being on a surface which is to support the pipeline; repeatedly and sequentially depositing inner component sections on at least a portion of the apparatus; at least partially supporting on the apparatus each of the inner component sections which is deposited on the apparatus; providing inner component section supporting means on said surface; forcing each of the inner component sections supported on the apparatus from the apparatus to the supporting means to thereby transfer at least some of the support of the inner component sections to the inner component section supporting means and to place the inner component sections in end-to-end relationship; placing the formable outer component at least beneath the inner component sections supported by the inner component section supporting means to thereby provide additional support for the inner component sections; and initiating said step of placing for a plurality of said outer component sections subsequent to said step of forcing said plurality of inner component sections.
