CONSTRUCTION METHOD FOR PIPELINE |
摘要 |
<p><P>PROBLEM TO BE SOLVED: To reduce construction cost by sharing construction work of pipelines for power cable and pipelines for gas transportation by making a part of pipelines for power cable which are provided in parallel capable of being used as pipelines for gas transportation with an inner face lining method using shape-memory polyetylene pipes. <P>SOLUTION: An inner face of at least one pipeline 1g of two or more parallel provided power cable pipelines 1, ... is lined with a polyolefine pipe 3. At least one pipeline 1g is set as the pipeline for gas transportation. In this case, lining is made possible as a bent and reduced polyolefine pipe having shape-memory of circle section area is inserted into at least the pipeline 1g and the inserted pipe is enlarged and restored to be its original shape. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
