Description

Detailed Description of the Invention

A. Object of the invention (1) Industrial field of application The present invention relates to a lining construction apparatus for constructing a lining layer on an inner surface of the sewer pipe, in an existing sewer pipe such as a sewer pipe, a water pipe and a gas pipe, and More specifically, the present invention relates to a lining construction device in which a tubular body formed by spirally winding a strip-shaped member made of a long plate-like member, a so-called lining pipe, is inserted into a pipe.

(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.

(3) Problem to be Solved by the Invention Therefore, in order to solve the problem in the prior art, the present invention takes a new idea and makes a lining without making a special change to the structure of the belt-shaped member of the prior art. 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.

B. Configuration of the Invention (1) Means for Solving Problems The lining construction device in the pipe of the present invention has the following configuration in order to achieve the above object. That is, in the pipe, a long strip-shaped member having joints formed on both side edges and continuously supplied is spirally wound, and a tubular body formed by engaging mutually adjacent joints is left. A pipe manufacturing apparatus for additionally forming a tubular body with a belt-shaped member newly supplied in front of the already formed tubular body, which has rigidity and retains rigidity while forming an annular shape having a required width, A mounting frame arranged inside the tubular body, arranged on the outer periphery of the mounting frame and at a predetermined pitch in the circumferential direction,
A plurality of guide rollers abutting on the inner surface of the tubular body, mounted via the mounting frame, arranged at a site where the already formed tubular body and a newly supplied strip-shaped member are closed, and sandwiching the strip-shaped member. It is characterized by comprising a joining mechanism portion composed of an outer surface roller and an inner surface roller to be worn.

(2) Action The joints that are in contact with each other are engaged by the sandwiching action of the outer surface roller and the inner surface roller of the joining mechanism portion at the closed portion of the belt-shaped member. The outer roller engages with the groove formed on the outer surface of the belt-shaped member, and thus advances in the pipe axis direction at a predetermined pitch together with the newly supplied belt-shaped member, and the joining mechanism portion is always located at the closed portion. As a result, the present construction apparatus revolves around the whole, and the belt-shaped members are continuously closed to produce a pipe. The mounting frame is formed in an annular shape and is rigidly formed, and a guide roller disposed on the outer surface stably produces a tubular body having a constant diameter. Further, the mounting frame carries the divided body into the pipe and is assembled in the pipe.
