The gap between the newly formed spiral pipe and the existing pipe is then filled with grout to create an integrated composite structure.<br \/>The method was presented as a safe and practical solution for sewer pipe renewal, offering the advantages of reduced road excavation and fewer tasks requiring workers to enter the pipeline.<\/p>\n<\/blockquote>\n<div

pipe rehabilitation method that forms a new pipe inside an existing sewer pipeline by spirally winding rigid PVC strips.<\/div>\n<\/details>\n<details class=\"faq-item\">\n<summary>How is the new pipe integrated with the existing pipe?<\/summary>\n<div class=\"faq-answer\">After the spiral pipe is formed inside the existing pipeline, grout is injected into the gap between the new pipe and the existing pipe, creating an integrated composite structure.<\/div>\n<\/details>\n<details class=\"faq-item\">\n<summary>What are the main advantages of the method?<\/summary>\n<div class=\"faq-answer\">The method can reduce the need for road excavation, help minimize traffic disruption, and improve safety by reducing the amount of work that requires workers to enter the pipeline.<\/div>\n<\/details>\n<\/div>\n<details class=\"video-transcript\">\n<summary>View video transcript<\/summary>\n<div class=\"transcript-content\">We are SW Liner Construction Association.<br \/>The method we are introducing is called the SW Liner Method.<br \/>The SW Liner Method forms a new pipe inside an existing sewer pipeline by winding strip-shaped rigid PVC boards in a spiral form.<br \/>There is a gap between the spiral pipe and the existing pipe, and this gap is filled with grout to create an integrated structure with the existing pipe.<br \/>The advantages are that road excavation is not required, and because there is less work that requires entering the pipeline, it is a highly safe construction method.<\/div>\n<\/details>\n<h2>Contact the company<\/h2>\n<div
