Description

[Detailed description of the device]

This invention relates to a pipe line fixing structure,
Specifically, it relates to a secondary pipe lining, or a pipe fixing structure used when piping in an existing pipe.

[0002]

2. Description of the Related Art Conventionally, when a secondary shield lining or pipe in an existing conduit is used, as shown in FIG. 4, the outer periphery of the conduit A and the conduit are supported to prevent floating of the new conduit due to movement or buoyancy. A support material C made of wood is arranged in the radial direction between the body B and a wedge D, and the pipe A is fixed.

[0003]

By the way, in the case of the above support structure,
There is no problem if the pipeline A does not move by external force at all until the completion of construction. However, if the pipeline D may move slightly due to external force or buoyancy due to mortar injection, etc. There is a drawback that the support material may fall off.

[0004]

In view of the above problems, the present invention is a pipe line fixing structure in which the supporting member does not move at all even when an external force insufficient is applied, though it is a mounting method using exactly the same means as the conventional one. The purpose is to provide.

[0005]

That is, in the pipe line fixing structure of the present invention, a C-shaped steel band having substantially the same curvature as the pipe is applied to the outer periphery of the pipe line, and the outer peripheral surface of the band is formed. A support member that extends in the radial direction with respect to the conduit via a wedge is provided between the conduit support members, and a U-shaped snail between the support member side surface and the band inner surface forms the wedge. It is characterized in that it is driven and fixed so as to sandwich it.

[0006]

EXAMPLES The present invention will be described below with reference to examples. FIG.
2 is a sectional view of an embodiment of the present invention, FIG. 2 is an enlarged sectional view of an essential part of the embodiment, and FIG. 3 is an enlarged side view of an essential part of the embodiment.

The pipeline fixing structure of the present invention is made of a steel having a C-shape having substantially the same curvature as that of the tube 1 on the outer periphery of the pipeline 1 newly installed in the shield secondary lining or the piping work in the existing conduit. 4. The band 2 is applied to the outer peripheral surface of the band 2, and the support members 4 ... 4 that extend in the radial direction with respect to the pipe line 1 via the wedges 3 are formed of, for example, a concrete section or the like. 6 is provided between the side surface 4A of the support member 4 and the inner surface of the band 2, and is formed by driving and fixing so that the wedges 3, 3 are sandwiched between the wedges 3, 3.

[0008]

In the above, the pipe 1 is supported by the C-shaped steel band 2 which is in contact with the pipe 1.
Are supported by the support member 4 via the wedge 3. Further, since the snare 6 is driven between the steel band 2 and the supporting member 4, even if the conduit 1 may be moved by an external force, the wedge 3 is fixed by the snail and naturally. It will never loosen.

[0009]

As described above, according to the present invention, it is possible to reliably prevent the wedge driven in for adjusting the supporting force from being loosened naturally by the fixing force of the snares, and the piping work can be safely performed. It becomes.

(57) [Scope of utility model registration request] 1. A C having substantially the same curvature as the pipe on the outer circumference of the pipe.
A steel band forming a mold is applied to the outer peripheral surface of the band, and a support member extending in the radial direction with respect to the conduit via a wedge is provided between the conduit support members, and the side surface of the support member and the band. A conduit fixing structure, characterized in that a U-shaped snail between the inner surface of the body and the inner surface is driven and fixed so as to sandwich the wedge. [0001]
