枝管ライニング工法
Document Type and Number:
Japanese Patent JP4904039
Kind Code:
B2
Abstract:
A lateral pipe lining material (1) comprises a tubular resin absorbing material (2) impregnated with a setting resin, which has a flange (3) at one end thereof and whose outer surface is coated with a highly airtight film (4). A sealing tube (5) is detachably attached to the outer circumferential surface of the tubular resin absorbing material (2). The lateral pipe lining material is introduced inside a main pipe (30) and its flange (3) is brought into tight contact with the lateral pipe opening. The lateral pipe lining material (1) including the sealing tube (5) is then everted and inserted by fluid pressure inside a lateral pipe (31) toward the ground level. After the setting resin is cured, the sealing tube (5) is removed from the lateral pipe lining material. This enables the lining of a lateral pipe to always be performed reliably, regardless of the aboveground circumstances.
