Abstract

(57) [Summary] (with amendments) [Purpose] To obtain a pipe fixing structure that reliably prevents movement of newly constructed pipes due to external force or buoyancy in piping without secondary shield lining or existing pipes. [Structure] A C-shaped steel band 2 with approximately the same curvature as the pipe is applied to the outer circumference of the pipe, and a wedge 3 is placed on the outer circumferential surface of the band.
A support member 4 extending in the radial direction with respect to the pipe line is installed between the pipe support members 5, and a U-shaped cutout 6 is provided between the side surface of the support member and the inner surface of the band body. It is constructed by driving and fixing a wedge between the pipes, and the member for fixing the pipe line is integrated between the C-shaped steel band and the supporting member using a casing to prevent loosening.

Description

[Detailed explanation of the idea] [Industrial application field]

This idea is related to the pipe fixing structure, and in detail, the secondary shield lining, or the existing pipe culvert. This invention relates to a pipe fixing structure used for internal piping.

0002

[Conventional technology]

Conventionally, when performing secondary shield lining or piping inside an existing pipe, it was necessary to move the new pipe. Alternatively, to prevent floating due to buoyancy, as shown in Figure 4, the outer circumference of pipe A and pipe support B A support material C made of wood is placed in the radial direction between the Make a decision.

0003

[Problems with conventional technology]

By the way, in the case of the above support structure, pipe A will not move at all due to external force until the construction is completed. If not, there is no problem, but if there is even a slight movement due to external force or buoyancy due to mortar injection, etc. If it moves, the wedge D will loosen, and once this happens, the support material will come off and fall off. There was a drawback that it could cause problems.

0004

[Problem that the idea aims to solve]

This idea was developed in view of the above problems, and although it is an installation method that uses exactly the same method as the conventional method, Provides a pipe fixing structure that prevents the support material from moving even if insufficient external force is applied. It was done for the purpose of

[0005]

[Means to solve the problem]

That is, the conduit fixing structure of this invention has a C-shaped structure on the outer periphery of the conduit, which has approximately the same curvature as that of the conduit. A steel band with a diameter of A support member extending in the direction is installed between the conduit support members, and a side surface of the support member and the band member A U-shaped cutout is driven in and fixed between the inner surface and the wedge so as to sandwich the wedge. It is characterized by:

【Example】

Next, this invention will be explained using examples. Fig. 1 is a sectional view of an embodiment of this invention, Fig. 2 is an enlarged sectional view of the main part of the embodiment, and Fig. 3 is an actual sectional view. FIG. 3 is an enlarged side view of the main part of the example.

[0007] The pipeline fixing structure of this idea is suitable for secondary shield lining or piping work inside existing pipe conduits. A C-shaped steel bar with approximately the same curvature as the pipe 1 is installed around the outer periphery of the newly installed pipe 1. band 2 is applied to the outer peripheral surface of the band 2 through wedges 3, 3 in the radial direction with respect to the pipe line 1. A conduit in which the extending supporting members 4...4 are made of, for example, concrete segments. It is installed between the supports 5 and forms a U-shape between the side surface 4A of the support material 4 and the inner surface of the band 2. The cutout shells 6...6 are driven and fixed so as to sandwich the wedges 3, 3.

[0008]

[Effect]

In the above, the pipe line 1 is supported by a C-shaped steel band 2 that is in contact with the pipe line 1. This steel band 2 is supported by a support member 4 via a wedge 3. Additionally, steel Since a cutout 6 is driven between the band 2 and the support material 4, if the pipe line 1 Even if the wedge 3 moves due to external force, the wedge 3 remains fixed by the casing. It will not loosen naturally.

[0009]

[Effect of the idea]

As explained above, according to this invention, the wedge driven to adjust the supporting force The fixing force of the spool reliably prevents natural loosening, ensuring safe piping. This makes it possible to work.
