PIPE REGENERATION METHOD
PROBLEM TO BE SOLVED: To regenerate an existing pipe while preventing deformation of a regeneration pipe by injecting a filler without assembling a timbering member in the regeneration pipe.SOLUTION: Segments 1 obtained by integrally forming a side plate and an end plate vertically disposed on a peripheral edge of an inner face plate constituting an inner peripheral face, with plastic, are connected in a circumferential direction to assemble pipe units. The pipe units are connected in a pipe longitudinal direction while disposing regeneration pipe position adjustment spacers 50, 60-62 between an existing pipe 21 and the regeneration pipe 40. The regeneration pipe is laid in the existing pipe, and then a filler 30 is injected between the regeneration pipe and the existing pipe. The plurality of spacers are disposed over the whole circumference between the regeneration pipe and the existing pipe with a thickness according to a clearance between the regeneration pipe and the existing pipe.SELECTED DRAWING: Figure 5
【課題】更生管内に支保工を組み立てることなく、充填材の注入ができ、更生管の変形を防止して既設管の更生を行う。【解決手段】内周面を構成する内面板の周縁に立設された側板並びに端板とをプラスチックによって一体に形成してなるセグメント１を、周方向に連結して管ユニットを組み立てる。更生管の位置調整用スペーサー５０、６０〜６２を既設管２１と更生管４０の間に配置しながら管ユニットを管長方向に連結する。更生管を既設管内に敷設した後、更生管と既設管の間に充填材３０を注入する。スペーサーは、更生管と既設管の間に全周に渡って更生管と既設管の間の隙間に応じた厚さで複数配置される。【選択図】図５
