ることができないことも問題点の一つである。(2) Conventional Technology As one aspect of such a lining construction technology, for example, Japanese Patent Publication No. 312136/1990 is known. That is, in this conventional technique, a lining pipe formed by spirally winding a continuously supplied strip-shaped member is started from a pipe-making machine installed in a human hole of the pipe and rotated in an existing pipe. It is sent with movement, that is, thrust force. However, according to this conventional technique, as the length of the lining pipe becomes longer, the weight of the lining pipe increases and the frictional resistance between the outer surface of the lining pipe and the pipe wall of the pipe increases, which requires a large thrust force. It will be. In addition, the weight per unit length increases as the diameter increases, and a larger thrust force is required. For this reason, the power equipment becomes large in size to obtain the necessary thrust force, and the equipment cost increases. Therefore, this conventional technique has a problem in lengthening and increasing the diameter. Furthermore, in this conventional technique, it is also a problem that the bending of the pipe cannot be dealt with.

It is an object of the present invention to provide a lining construction technique capable of appropriately responding to an increase in the length and diameter of a pipe, and further a bending of a pipe. Therefore, the present invention was made based on the finding that it is possible to cope with the lengthening and the diameter increase by leaving the lining pipe formed by the spiral winding.
