Description

Technical Field

[0001] The present invention relates to a rehabilitation body used for rehabilitating an existing tubular structure and a method for rehabilitating the inner surface of an existing tubular structure using this rehabilitation body.

Background Art

[0002] Conventionally, for existing tubular structures (existing pipes) such as aging sewer pipes, since the work of replacing them with new pipes is large-scale, work for reinforcing or repairing the existing pipes has been carried out.

[0003] For such work, a rehabilitation method is used to improve the aging existing pipe so that it functions equally or better than a new pipe.

[0004] As an example of such a rehabilitation method, a belt-shaped sheet material made of a thermoplastic resin as a repair member is spirally installed along the inner surface of an existing pipe so that a spiral pipe is formed inside the existing pipe, and a filler (for example, mortar, concrete, etc.) is filled in the gap between this spiral pipe and the existing pipe to rehabilitate the existing pipe.

[0005] In addition, Patent Document 1 discloses a method for rehabilitating an existing pipe using such a spiral pipe.

Summary of the Invention

Problems to be Solved by the Invention

[0007] However, in the structure of a rehabilitated pipe obtained by installing a spiral pipe inside an existing pipe and filling the space between the existing pipe and the spiral pipe with a filler such as mortar, as disclosed in Patent Document 1, there was a problem in that the attachment strength of the spiral pipe included in the rehabilitated pipe to the existing pipe was insufficient.

[0010] The present invention aims to provide a rehabilitation device that allows the support fixtures (fixing frames) that support the rehabilitation panel to be installed in the precise position on the inner surface of the existing pipe as designed, even when construction is being carried out while sewage or other sewer is flowing (when construction is being carried out under a shared pipe).

[0029] The present invention is described below. Unless otherwise specified, terms used herein should be understood to have the meaning commonly used in the art. Therefore, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. In case of any conflict, this specification (including definitions) shall prevail.

[0030] In this specification, "approximately" means within ±10% of the following number.

[0031] [The first invention of this application] The present invention aims to provide a rehabilitation device that allows the support fixtures (fixing frames) that support the rehabilitation panel to be installed in the precise position on the inner surface of the existing pipe as designed, even when sewage or other sewer is flowing (during construction under a shared pipe). A rehabilitation device that rehabilitates the inner surface of an existing tubular structure, Rehabilitated individuals are, Multiple rail members that can be fixed to the inner surface, Multiple rehabilitation panels for covering the inner surface of a tubular structure, Multiple fixing frames for securing multiple rehabilitation panels and Equipped with, Each of the rail members is equipped with an engaging portion that engages with a plurality of fixed frames. The above problem is solved by providing a refurbished unit in which multiple fixed frames are configured to have engaging portions that can engage with multiple rail members when each is placed on multiple rail members in a substantially perpendicular manner.

[0032] Therefore, the rehabilitation structure of the present invention is not particularly limited as long as it comprises a plurality of rail members that can be fixed to the inner surface and a plurality of fixing frames for fixing a plurality of rehabilitation panels that cover the inner surface of a tubular structure, and the plurality of rail members and the plurality of fixing frames are configured to be able to engage at their intersections.

[0033] For example, the multiple rail members may be arranged in the axial direction of the tubular structure, or they may be arranged in a direction that makes a predetermined angle (an angle less than 90°) with respect to the axial direction of the tubular structure.

[0034] Multiple fixing frames are members for fixing multiple rehabilitation panels, and may be plate-shaped or rod-shaped members, as long as they intersect with rail members and can engage at the intersection.

[0035] Furthermore, the engagement between the engaging portions of the multiple rail members and the engaged portions of the multiple fixed frames may be configured to be achieved by relative movement between the rail members and the fixed frames in the axial direction, or by relative movement in a direction that makes a predetermined angle (an angle less than 90°) with respect to the axial direction of the tubular structure.

[0036] Furthermore, this application includes the following inventions:

[0037] [Second invention of this application] This invention, like the first invention of the present application, relates to the structure of a rehabilitated tubular structure, and aims to improve the workability of the assembly process at the construction site by attaching a large number of rehabilitation panels to a fixed frame. A rehabilitation panel unit for rehabilitating the inner surface of an existing tubular structure, Multiple rehabilitation panels for covering the inner surface of a tubular structure, Multiple fixing frames for securing multiple rehabilitation panels and They are integrated into one unit. The above problems are solved by providing a rehabilitation panel unit in which multiple fixed frames are configured to each have an engaging portion that can be fitted into the engaging portions of multiple rail members fixed to the inner surface of a tubular structure.

[0038] Therefore, the rehabilitation panel unit of the present invention integrates the rehabilitation panel and the fixing frame, and the other configurations are not limited as long as the fixing frame is capable of engaging with a plurality of rail members fixed to the inner surface of a tubular structure.

[0039] For example, it is preferable that a flexible, bellows-shaped joint material, which integrates multiple joint materials capable of filling multiple gaps between adjacent rehabilitation panels among a plurality of rehabilitation panels, is integrated with the rehabilitation panel.

[0040] This is because it enhances the waterproofing effect between adjacent rehabilitation panels among multiple rehabilitation panels.

[0041] Furthermore, it is preferable that the rehabilitation panel has a projection on the surface facing the surface into which the joint material is filled, and that the fixing frame has an elastic body that can be fitted onto the projection of the rehabilitation panel. This is because the installation of the rehabilitation panel to the fixing frame becomes a simple operation of just pushing the projection of the rehabilitation panel into the elastic body of the fixing frame. Here, the elastic body is made of spring steel, but it may also be made of rubber. Preferably, the joint material consists of multiple joint materials integrated together. For example, multiple joint materials may be in the form of a flexible bellows-like sheet that is integrated together, or it may be able to follow changes in the spacing between adjacent rehabilitation panels into which the joint material is inserted.

[0042] Furthermore, the joint material and the rehabilitation panel may be integrated by welding, or they may be integrated by adhesive or fastening means.

[0043] [The third invention of this application] This invention, like the first invention of the present application, relates to the structure of a rehabilitated tubular structure, and aims to provide a rehabilitated structure that can suppress the peeling of joint material filling gaps even when gaps between adjacent rehabilitated panels in the axial direction of the tubular structure, which is the longitudinal direction of the rehabilitated panels, widen, thereby reducing the deterioration of watertightness. A rehabilitation material used for rehabilitating the inner surface of existing tubular structures, Multiple rehabilitation panels for covering the inner surface of a tubular structure, Multiple joint materials to be filled into the gaps between adjacent rehabilitation panels in the axial direction of a tubular structure and Equipped with, The above problem is solved by providing a rehabilitation material that has a deformable structure to follow the widening of the gap between adjacent rehabilitation panels.

[0044] Therefore, the rehabilitation structure of the present invention is not limited to any other configurations, as long as it is formed by joining adjacent rehabilitation panels in the axial direction of a tubular structure with jointing material to create a single integrated structure.

[0045] For example, multiple joint materials may be fixed to the rehabilitation panel by resin welding, or they may be fixed with adhesive. Alternatively, such joint materials may be inserted between adjacent rehabilitation panels arranged perpendicular to the axial direction of the existing tubular structure.

[0046] [The fourth invention of this application] This invention is a method for rehabilitating the inner surface of an existing tubular structure using the rail member of the first invention and the rehabilitation panel unit of the second invention of this application, The challenges were to install the support fixtures (fixing frames) that support the rehabilitation panels in the precise positions on the inner surface of the existing pipes as designed, and to improve the workability of assembling the rehabilitation structure by attaching the rehabilitation panels to the fixing frames at the construction site. In advance, a rehabilitation panel unit is formed by fixing multiple rehabilitation panels for covering the inner surface of a tubular structure to multiple fixed frames, At the construction site, multiple rail members are fixed to the inner surface along the circumferential surface of the annular structure, By fitting multiple fixed frames onto multiple rail members, the integrated rehabilitation panel unit is fixed to multiple rails. The above problems are solved by providing a method that includes [the specified element].

[0047] Therefore, the method of the present invention is not limited to any other configurations, as long as it involves first fixing multiple rehabilitation panels to multiple fixed frames to create a rehabilitation panel unit, then fixing multiple rail members on the circumferential surface of an annular structure at the construction site, and finally fitting the multiple fixed frames included in the rehabilitation panel unit to the multiple rail members.

[0048] For example, it is preferable to further include filling and welding multiple flexible, bellows-shaped joint materials, which are integrated with multiple joint materials, into multiple gaps between adjacent rehabilitation panels of a rehabilitation panel unit, either in advance or at the construction site. This is because it increases the joint strength between adjacent rehabilitation panels.

[0049] Furthermore, at the construction site, it is preferable to fill the gaps between rehabilitation panel units that are arranged adjacent to each other in the axial direction of the tubular structure with another joint material (second joint material) and weld them together. This is because it increases the joint strength between rehabilitation panel units that are arranged adjacent to each other in the axial direction of the tubular structure.

[0050] The second joint material may be welded to the rehabilitation panel by resin welding, or it may be joined with an adhesive. Furthermore, it may have a deformable structure (a slit formed in a direction parallel to the gap) to follow the widening of the gap between adjacent rehabilitation panels.

[0051] Furthermore, this application includes the following methods:

[0052] The present invention is a method for rehabilitating the inner surface of an existing tubular structure, By arranging multiple rehabilitation panels to cover the inner surface, Each adjacent rehabilitation panel is filled with multiple jointing materials. Includes, Multiple joint materials have a deformable structure to accommodate the widening of gaps between adjacent rehabilitation panels.

[0053] Here, the joint material and the rehabilitation panels on either side are joined by resin welding.

[0054] Furthermore, the method of the present invention is A method for rehabilitating the inner surface of an existing tubular structure, To fix multiple rail members to the inner surface of a tubular structure along the circumferential surface of an annular structure, By fitting multiple fixing frames onto multiple rail members, the system is fixed to multiple rails. To fix multiple rehabilitation panels for covering the inner surface of a tubular structure to multiple fixed frames, It includes.

[0055] The following describes, with reference to the drawings, a rehabilitated organism and a rehabilitation method that implement all of the first to fourth inventions of this application.

[0056] (Embodiment 1) Figure 1 is a diagram illustrating the rehabilitated pipe 100 of the present invention. Figure 1(a) shows the portion 10a to be rehabilitated of the existing pipe 10, and Figure 1(b) shows the rehabilitated pipe 1000 with the rehabilitated pipe 100 installed on the portion 10a to be rehabilitated of the existing pipe 10. Figure 2 is an enlarged view of portion R in Figure 1, showing the positional relationship between the rail member 110 and the fixed frame 120 shown in Figure 1.

[0057] This rehabilitation device 100 is used to rehabilitate the inner surface of an existing tubular structure, for example, the inner surface of the part to be rehabilitated 10a of the existing pipe 10 shown in Figure 1(a). Here, as shown in Figure 1(b), the rehabilitation device 100 comprises a plurality of rail members 110 that can be fixed to the inner surface of the part to be rehabilitated 10a, a plurality of rehabilitation panels 130a for covering the inner surface of the part to be rehabilitated 10a, and a plurality of fixing frames 120 for fixing the plurality of rehabilitation panels 130a, and the plurality of fixing frames 120 are configured to engage with the plurality of rail members 110. The structure of each part of the rehabilitation device 100 will be described in detail below.

[0058] (Rail member 110 and fixing frame 120) As shown in Figure 2, the rail members 110 extend along the direction of the axis Ax of the part to be rehabilitated 10a (hereinafter referred to as the axial direction), are approximately perpendicular to the axial direction, and are arranged at predetermined intervals in a direction Bx parallel to the bottom surface of the part to be rehabilitated 10a (hereinafter referred to as the direction perpendicular to the axis). The rail members 110 are fixed to the inner surface of the part to be rehabilitated 10a (i.e., the existing tubular structure 10) by anchor members (not shown), such as anchor bolts.

[0059] Furthermore, the fixed frame 120 extends along the direction Bx perpendicular to the axis and is arranged on the rail member 110 at predetermined intervals along the axial direction.

[0060] At the intersection of the rail member 110 and the fixed frame 120, the two engage with each other, thereby fixing the fixed frame 120 to the rail member 110.

[0061] Figure 3 shows the specific structure of the rail member 110 and the fixed frame 120 shown in Figure 2.

[0062] Each of the multiple rail members 110 is provided with an engaging portion 110a that engages with a multiple fixed frame 120, and each of the multiple fixed frames 120 is configured to have an engaged portion 120a that can engage with the multiple rail members 110 when placed on the multiple rail members 110 in a substantially perpendicular manner.

[0063] Figure 4 shows the engagement state between the rail member 110 and the fixed frame 120 shown in Figure 2, that is, the state in which the engaging portion 110a of the rail member 110 and the engaged portion 120a of the fixed frame 120 are engaged. Figure 4(a) is a side view (viewed from the X direction in Figure 3), and Figure 4(b) is a top view (viewed from the Y direction in Figure 3). Figure 5 shows the direction of movement of the fixed frame 120 for engaging the fixed frame 120 with the rail member 110 shown in Figure 2, indicated by arrows. Figure 5(a) is a side view (viewed from the X direction in Figure 3), and Figure 5(b) is a top view (viewed from the Y direction in Figure 3).

[0064] The engaging portion 110a of the rail member 110 is formed by a notch along the longitudinal direction of the rail member 110, which is formed on the upper part of the side wall portion of the rail member 110, which has a U-shaped cross-section. Here, the side wall portion of the rail member 110 is a wall portion perpendicular to the inner surface (for example, the bottom surface) of the portion to be refurbished 10a.

[0065] Furthermore, the fixing frame 120 is a plate-shaped member arranged parallel to the inner surface (for example, the bottom surface) of the part to be rehabilitated 10a, and the engaged portion 120a of the fixing frame 120 is formed by a cut along the longitudinal direction of the rail member 110 formed in this plate-shaped member.

[0066] In this way, the notch formed in the wall portion of the rail member 110 perpendicular to the inner surface of the portion to be rehabilitated 10a and the notch formed in the plate-shaped member of the fixed frame 120 parallel to the inner surface of the portion to be rehabilitated 10a interlock, resulting in a strong engagement between the engaging portion 110a of the rail member 110 and the engaged portion 120a of the fixed frame 120 (see Figures 4(a) and (b)).

[0067] As described above, a fixed frame 120 fixed to the rail member 110 has an integrated rehabilitation panel 130 attached to it, which is made by joining multiple rehabilitation panels 130a together with joint material 130b, and a filler material 100b such as cement is filled between the integrated rehabilitation panel 130 and the inner surface of the part to be rehabilitated 10a.

[0068] In a rehabilitated body 100 with this configuration, when attaching multiple rehabilitation panels 130a to the inner surface of the part to be rehabilitated 10a, a rehabilitation panel unit 100a, which consists of an integrated rehabilitation panel 130 manufactured in advance at the factory and further attached to a fixed frame 120, is used as the unit of attachment. The fixed frame 120 incorporated into the rehabilitation panel unit 100a is then placed on a rail member 110 fixed to the inner surface of the part to be rehabilitated 10a and moved as shown in Figure 5 to engage the two, thereby enabling the attachment of multiple rehabilitation panels 130a to the inner surface of the part to be rehabilitated 10a with good workability.

[0069] Alternatively, the attachment of multiple rehabilitation panels 130a to the part to be rehabilitated 10a may be performed by placing the fixing frame 120 on the rail member 110 fixed to the inner surface of the part to be rehabilitated 10a and moving it to engage the two, and then attaching the integrated rehabilitation panel 130 to the fixing frame.

[0070] The structure of the integrated rehabilitation panel 130 and the rehabilitation panel unit 100a will be described below.

[0071] (Integrated rehabilitation panel 130) Figure 6 is a diagram illustrating the integrated rehabilitation panel 130 shown in Figure 1, where Figure 6(a) is a perspective view and Figure 6(b) is a side view (viewed from the Z direction of Figure 6(a)). Figure 7 is a diagram illustrating the process of manufacturing the integrated rehabilitation panel 130 shown in Figure 6, where Figure 7(a) shows the process of fitting a bellows-shaped joint material 130b between adjacent rehabilitation panels 130a, and Figure 7(b) shows the state after the bellows-shaped joint material 130b has been fitted between adjacent rehabilitation panels 130a.

[0072] The integrated rehabilitation panel 130 (Figures 6 and 7(b)) is constructed by joining multiple rehabilitation panels 130a together using a bellows-shaped joint material 130b, as shown in Figure 7(a), in order to avoid the work of fixing each elongated rehabilitation panel 130a to the fixing frame 120 one by one at the work site (inside the existing pipe 10). Here, the rehabilitation panel 130 and the joint material 130b may be joined by hot air welding.

[0073] (Rehabilitation panel unit 100a) Figure 8 is a diagram illustrating the structure of the rehabilitation panel unit 100a shown in Figure 1, where Figure 8(a) is a perspective view and Figure 8(b) is a side view (viewed from the Z direction of Figure 8(a)). Figure 9 shows how the integrated rehabilitation panel 130 shown in Figure 6 is attached to the fixed frame 120, where Figure 9(a) is a perspective view and Figure 9(b) is a side view (viewed from the Z direction of Figure 9(a)). Figure 10 is an enlarged view of Figure 9(b) showing how the integrated rehabilitation panel 130 is fixed to the fixed frame 120, where Figure 10(a) shows the process of pressing the integrated rehabilitation panel 130 against the fixed frame 120, and Figure 10(b) shows the state in which the integrated rehabilitation panel 130 is fixed to the fixed frame 120.

[0074] As shown in Figure 10(a), the integrated rehabilitation panel 130, which includes multiple rehabilitation panels 130a, is aligned with the fixed frame 120 and pressed down, thereby fixing the multiple rehabilitation panels 130a together as an integrated rehabilitation panel 130 to the fixed frame 120 (Figures 9(a), (b), and 10(b)). As a result, a rehabilitation panel unit 100a is formed as a factory-assembled component that is fixed to the rail member 110 on site.

[0075] Next, we will explain the on-site work of attaching multiple rehabilitation panels 130a to the inner surface of the part to be rehabilitated 10a.

[0076] Figure 11 shows the process of attaching the rehabilitation panel unit 100a shown in Figure 8 to the rail member 110, where Figure 11(a) is a perspective view and Figure 11(b) is a side view (viewed from the Z direction of Figure 11(a)). Figure 12 is a diagram to explain the structure of the rehabilitation panel unit 100a fixed to the rail member 110 (Figure 1(b)), where Figure 12(a) is a perspective view and Figure 12(b) is a side view (viewed from the Z direction of Figure 12(a)).

[0077] As shown in Figure 9, the rehabilitation panel unit 100a (Figure 8) consists of multiple integrated rehabilitation panels 130 attached to multiple fixed frames 120, with the elastic bodies 121 of the fixed frames 120 gripping the linear projections 131 on the back surface of the integrated rehabilitation panels 130.

[0078] At the site, the rail member 11 is fixed to the inner surface of the section to be rehabilitated 10a during the pipe cleaning and pretreatment process. Then, during the installation of the aforementioned rehabilitation panel unit 100a under common use (while sewage is flowing), as shown in Figure 11, it is slid on the rail member 110 fixed to the inner surface of the section to be rehabilitated 10a, engaging the engaging portion 120a of the fixing frame 120 with the engaging portion 110a of the rail member 110. As a result, as shown in Figure 12, multiple rehabilitation panels 130a are fixed to the inner surface of the section to be rehabilitated 10a via the fixing frame 120 and the rail member 110 (see Figures 12 and 1).

[0079] By using a rehabilitation panel unit 100a that includes a fixing frame 120 along with multiple rehabilitation panels 130a, multiple rehabilitation panels 130a can be fixed to the rail member 110 all at once, making it possible to efficiently attach multiple rehabilitation panels 130a to the inner surface of the part to be rehabilitated 10a.

[0080] Subsequently, filler material 100b is filled between multiple rehabilitation panels 130a and the inner surface of the part to be rehabilitated 10a, and the rehabilitated material 100 is installed on the part to be rehabilitated 10a of the existing pipe 10 to complete the rehabilitation work on the existing pipe 10.

[0081] Thus, in this embodiment 1, it is possible to obtain a rehabilitated pipe in which the support fixtures (fixing frames) that support the rehabilitation panel can be installed in the precise position on the inner surface of the existing pipe as designed, even when sewage or other sewer is flowing (during construction under a shared pipe).

[0082] Furthermore, the joint material 130b is not limited to the bellows-shaped type described above, but may be of other shapes as well.

[0083] Figure 13 is a diagram illustrating other shapes of joint material 130b, where Figure 13(a) shows joint material 131 having a slit 131a, and Figure 13(b) shows the state of joint material 131 following the increase in the gap between adjacent rehabilitation panel units 100a.

[0084] As shown in Figure 13(a), the joint material 131 is inserted into the gap between adjacent rehabilitation panel units 100a and joined to the rehabilitation panel units 100a by welding resin 132, with a slit 131a provided in the center of the joint material 131.

[0085] In a joint material 131 with this configuration, even if the gap between adjacent rehabilitation panel units 100a increases due to the effects of an earthquake or the like, the joint material 131 will deform so that the slit 131a expands, thereby suppressing the peeling of the joint material 131 from the rehabilitation panel units 100a and ensuring watertightness between the units. The joint material 131 and the rehabilitation panel units (specifically rehabilitation panels) on both sides may be joined by resin welding. Furthermore, the gap into which the joint material 131 is embedded may be between adjacent rehabilitation panel units or between rehabilitation panels aligned in the axial direction of the tubular structure, or between adjacent rehabilitation panel units or between rehabilitation panels aligned perpendicular to the axial direction of the tubular structure.
