を流し込む工法が行われているが、以下述べるような問
題点が指摘されていた。DETAILED DESCRIPTION OF THE INVENTION When a conventional concrete main pipe is connected to a branch pipe made of vinyl chloride, a waterproofing agent is attached to the surface of an untreated polyvinyl chloride pipe, inserted and fixed, and then concrete is poured into the connection portion. Although the construction method has been implemented, the following problems have been pointed out.
（１）塩化ビニール管表面は、無処理のままでは有機系
の止水剤及び流し込みモルタルとの接着は不完全かつ不
良であるために、一体化せずに打継面からの漏水が生じ
る。(1) Since the surface of the vinyl chloride pipe is not completely treated and has an incomplete and poor adhesion to the organic water-blocking agent and the poured mortar, water leaks from the joint surface without being integrated.
