[Problem] To provide a means for a strip material (A) that can be spirally wound to construct a rehabilitated pipe, the means providing excellent conformability when an existing pipe has a corner portion or when an external force is applied to the new pipe body due to an earthquake or the like. [Solution] The strip material (A) comprises at least: an elongated belt portion 10; a fitting recess portion 20 provided at one end in the shorter direction on one surface side of the belt portion 10; a fitting projection portion 30 provided at the other end in the shorter direction on the one surface side of the belt portion 10; and a folded portion 50 provided midway along the shorter direction on the one surface side of the belt portion 10. A widening slit 60 is provided on the one surface side of the belt portion 10 between a connection part between the belt portion 10 and one end of the folded potion 50 and a connection part between the band portion 10 and the other end of the folded portion 50.

The invention relates to a method for laying a pipeline wound from profiled plastic strips using a winding machine, which circulates in a winding basket on a guide track, in an open channel trench, in particular in the form of a wastewater line. The aim of the invention is to provide a simple and inexpensive laying process. This is achieved by arranging a laying vehicle (10) on an opened trench section (4) of the laying trench (1), wherein profiled plastic strips (18) are removed from a storage drum (17), which is provided on the laying vehicle (10) or in the vicinity of the vehicle and which comprises a supply of profiled plastic strips, and fed to the pipe-producing device (6). The pipe-producing device (6) is held on a holding arm (12) in an oscillating manner and is lowered to almost the bottom (4.1) of the trench in the region of the opened trench section (4) of the laying trench (1). In the pipe-producing device (6), the profiled plastic strips (18) are joined to the last winding (5.1) of the already finished wound pipe (5), thereby latching the adjacent edge regions of the fed profiled plastic strip (18) and the profiled plastic strip (18) of the last finished winding (5.1), by means of a circulating winding basket (30) in a known manner. The pipe-producing device (6) in the winding basket (30) is supplied with energy by the drive of the laying vehicle (10), said energy being supplied via a supply line (14). The laying vehicle (10) follows the progress of the manufacture of the wound pipe (5), said pipe-producing device (6) following the elongation of the wound pipe (5) by means of the oscillating suspension on the holding arm (12). After the wound pipe (5) has been laid, the opened trench section (4.1) is refilled with soil (2.2).

Abrégé

The invention relates to a method and a device for repairing portions of channels (3), including non-round channels, by means of a wound tube (4) wound from a profile strip by a winding machine (20), the abutting edges of which strip are formed into tight joints, locked inside the wound tube (4) which can be introduced into the portion of the channel to be repaired. In order to avoid the disadvantages of the prior art, the plastic profile strip (4.1) is drawn from a storage spool (5) and fed to a winding machine (20) arranged in front of one of the openings of the channel to be repaired (3), said winding machine having a guide rail (25) adapted to the cross-portion of the channel, and adjacent edge regions fed onto this rotating winding former (30) locked in an overlapping manner to form a wound pipe (4) and said pipe is pushed or pulled into the channel portion (3).
