INNER PIPE BACK-FILLER MATERIAL
PROBLEM TO BE SOLVED: To provide an inner pipe back-filler material, which has an excellent underwater inseparation property, with which establishment in inner section in an existing pipe may be easily carried out, and which may enhance adhesion between an existing pipe and a revival pipe.SOLUTION: There is provide inner pipe back-filler material which contains at least cement composition and is injected into a gap between an existing pipe and a revival pipe arranged inside of the existing pipe and hardened to fix the revival pipe onto the existing pipe. The cement composition contains at least main material solution containing hydraulic cement and mixing solution, alumina cement, anhydrous plaster, cement mixing re-emulsification type powder resin defined by JIS A6203:2015, and hardening material solution containing mixing solution.SELECTED DRAWING: None
【課題】水中不分離性に優れ、既設管内部における施工が容易になるとともに、既設管と更生管との付着力を高めることが可能な管内張りの裏込め材を提供する。【解決手段】少なくともセメント系組成物を含み、既設管と、該既設管の内面側に配置された更生管との間に注入され、硬化することで既設管に更生管を固定する、管内張りの裏込め材であって、セメント系組成物は、少なくとも、水硬性セメント及び混練水を含む主材液と、アルミナセメント、無水石膏、ＪＩＳ Ａ６２０３：２０１５に規定されるセメント混和用再乳化形粉末樹脂及び混練水を含む硬化材液とが配合されてなる。【選択図】なし
