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, a lining for forming a tubular body by spirally winding a long strip-shaped member having joints formed on both side edges and continuously supplied in a pipe D, and engaging mutually adjacent joints. A construction device,
A mounting frame 1 having an extension portion radially arranged in the radial direction in the axial center portion of the pipe P, and one of the extension portions of the mounting frame 1, which is vertically formed on the outer surface of the belt-shaped member. Outer roller 1 having a collar portion that fits in the concave groove
5 and a joining mechanism portion 2 in which a joining roller portion composed of an inner surface roller 15 contacting the inner surface of the belt-shaped member is arranged at the tip portion of the extension portion, and the tip portion of the other extension portion of the mounting frame 1 And a guide mechanism portion 3 in which a guide roller 45 that contacts the inner surface of the belt-shaped member is arranged.

(2) Action At the closed portion of the belt-shaped member, the two outer surfaces of the joining roller portion and the inner surface rollers 15 and 16 are engaged with each other by the sandwiching action of the joints. The outer surface roller 15 engages with the groove of the strip-shaped member to advance in the pipe axis direction at a predetermined pitch together with the newly supplied strip-shaped member, and the joining roller portion is always located in 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 length of the extension of the mounting frame is constant, and the diameter of the tubular body to be produced is uniquely determined by the length of this extension. Then, the circularity of the tubular body manufactured by the joining roller portions 15 and 16 and the guide roller 45 attached to the radially extended portions is ensured.
