Summary of the Invention

[0007] [Figure 1] Side cross-sectional view of a pipe protection structure in one embodiment of the present disclosure [Figure 2] Front view showing a connector in one embodiment of the present disclosure. [Figure 3] A flowchart illustrating an overview of a pipe protection method in one embodiment of this disclosure. [Modes for carrying out the invention]

[0008] Hereinafter, one embodiment of this disclosure will be described with reference to the drawings.

[0009] (1) Overall structure As shown in Figures 1 and 2, the pipe protection structure 1 protects the pipe 2 that extends along the wall surface W. This pipe protection structure 1 comprises a protective sheet 4 that covers the outer surface of the pipe 2, a wall body 6 installed at a position opposite the wall surface W with the pipe 2 in between, a fixing member 8 that supports and fixes the wall body 6, a filling layer 10 formed between the wall surface W and the wall body 6, a maintenance space 12 formed adjacent to the pipe 2, and a reinforcing member 14 that reinforces the area above the filling layer 10.

[0010] In this embodiment, a wall W is provided as an example of a configuration that protects a sewer pipe 2 extending laterally (from front to back in Figure 1) along a slope adjacent to a residential area. Here, the pipe 2 is fixed to the upper surface of a pipe support 3 fixed to the wall W with a predetermined fastener (such as a bolt or band). However, the wall W may be a surface that forms part of a structure such as a tunnel or road, and the configuration may protect the pipe installed on this wall W. The surface of the wall W may be protected with mortar, stone cladding, concrete, or the like.

[0011] The protective sheet 4 covers the outer surface of the pipe 2 by wrapping it around the outer circumference and making it tightly adhered. In this way, the protective sheet 4 protects the pipe 2 from direct exposure to external stimuli such as ultraviolet rays and flying objects.

[0012] Furthermore, the protective sheet 4 is made of a material that is flexible, stretchable, elastic, waterproof, and water-resistant. Due to the waterproof and water-resistant properties of this protective sheet 4, the leakage of liquid components that unintentionally reach the outside of the pipe 2 due to damage or other factors is suppressed.

[0013] The wall 6 comprises a plurality of rod members 61 arranged horizontally at intervals opposite the wall surface W, and plate members 63 provided between adjacent rod members 61. The lower ends of the rod members 61 are connected to the wall surface W by wires 65. In this embodiment, single pipes are used as the rod members 61 and aluminum plates are used as the plate members 63.

[0014] Furthermore, the wall 6 has a height such that its upper end reaches above the pipe 2 and its lower end reaches below the pipe 2. As a result, the pipe 2 is hidden by the wall 6 when viewed from a position opposite the wall W.

[0015] The wall 6 is constructed by connecting multiple rods 61 and plates 63 vertically as appropriate, so as to be tall enough to conceal the pipes 2.

[0016] The fixing member 8 comprises a plate-shaped mounting portion 81 on which the wall body 6 is placed, and a support portion 83 that supports the mounting portion 81 from below. The support portion 83 is fixed to the wall surface W by an anchor 85, and the mounting portion 81 is fixed on top of it. In this embodiment, the support portion 83 is formed such that a part of it has a truss structure in a cross-sectional view intersecting the lateral direction, so that the mounting portion 81 can be stably supported along the wall surface W.

[0017] The filling layer 10 is formed by filling a resin material into the space S surrounded by the wall body 6 and the fixing member 8, and the pipe 2 is embedded in this resin material. In the present embodiment, a rigid urethane resin is used as the resin material, but it goes without saying that various resin materials can be used as the resin material.

[0018] The maintenance space 12 is a space formed so as to reach from the pipe 2 to the outside of the pipe protection structure 1. In the present embodiment, the maintenance space 12 is a space that reaches from the pipe 2 to the outside through the filling layer 10 from the upper part of the pipe protection structure 1, and is formed at a plurality of locations at intervals in the extending direction (lateral direction) of the pipe 2.

[0019] In the present embodiment, the maintenance space 12 is a space that extends upward from the pipe 2 through the filling layer 10 and reaches the outside, and is surrounded by the resin material forming the filling layer 10. However, a partition wall made of another material (for example, a resin material such as rigid vinyl chloride or concrete) may be provided between the maintenance space 12 and the filling layer 10, and the space surrounded by this partition wall may be used.

[0020] The reinforcing member 14 is a resin plate material having a predetermined thickness, and closes the space S surrounded by the wall surface W, the wall body 6, and the fixing member 8 from above by being arranged so as to connect at least the wall surface W and the upper end of the wall body 6.

[0021] As this reinforcing member 14, a plate material other than a resin material may be used according to the use and required performance of the pipe protection structure 1. Specifically, when a heavy object passes through the upper part of the pipe protection structure 1, a plate material made of asphalt, concrete, or the like may be used.

[0022] (2) Pipe protection method Subsequently, a pipe protection method in an embodiment of the present disclosure will be described using FIG. 3.

[0023] In this pipe protection method 100, first, a covering step is performed (S1). In this covering step, a protective sheet 4 is wrapped around the outer circumference of the pipe 2 and tightly adhered to cover the outer surface of the pipe 2.

[0024] Next, the fixing process is performed (S2). In this fixing process, the support part 83 is fixed to the wall surface W by anchors 85, and then the mounting part 81 is fixed on the support part 83 that has been fixed in this way.

[0025] Next, the installation process is carried out (S3). In this installation process, the wall body 6 is installed on the fixing member 8. In the installation process in this embodiment, a rod 61 is fixed on the fixing member 8, the lower end of the rod 61 and the wall surface W are connected by a wire 65, and then a plate 63 is placed between the fixed rods 61.

[0026] Next, a filling process is carried out (S4). In this filling process, the resin material is filled without any gaps into the space S surrounded by the wall surface W, the wall body 6, and the fixing member 8. Here, the space S is filled with a resin material made of foamed resin (an example of a foamed material), and as it hardens, a filling layer 10 is formed, in which the pipe 2 is embedded. In this embodiment, rigid urethane resin is used as the material made of foamed resin, but it goes without saying that various resin materials can be used as this material.

[0027] Next, a maintenance space formation process is carried out (S5). In this maintenance space formation process, the maintenance space 12 is formed by removing resin material that matches the shape of the maintenance space 12 from the upper region of the pipe 2 in the packed bed 10.

[0028] Next, a reinforcement process is carried out (S6). In this reinforcement process, a reinforcing member 14 is positioned to connect the wall surface W and the upper end of the wall body 6. Here, a resin reinforcing member 14 having a predetermined thickness is stretched and fixed between the wall surface W and the upper end of the wall body 6, closing off the space S surrounded by the wall surface W, the wall body 6 and the fixing member 8 from above. An opening 121 for a maintenance space 12 may be provided in a part of the reinforcing member 14.

[0029] (3) Variant Although embodiments of the present disclosure have been described above, the present disclosure is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention. In particular, the various modifications described herein can be combined as needed.

[0030] For example, in the above embodiment, the reinforcement step in the pipe protection method 100 is shown as being performed after the filling step. However, the reinforcement step may be performed in advance prior to the filling step to form a space S surrounded by the wall surface W, wall body 6, fixing member 8 and reinforcing member 14.

[0031] Furthermore, in the above embodiment, an example was given of a pipe protection method in which a filling layer 10 is formed in the space S in a filling step (S4), and then a maintenance space 12 is formed by removing resin material from a predetermined area of ​​the filling layer 10 in a maintenance space formation step (S5). However, the pipe protection method may also be configured to perform the maintenance space formation step before the filling step (S4). Specifically, in the maintenance space formation step, a partition wall formed in advance to match the shape of the maintenance space 12 is placed adjacent to the pipe 2 in the space S, and then in the filling step, resin material is filled into the space S excluding the area partitioned by this partition wall to form a filling layer 10.

[0032] (4) Effects As explained above, according to this embodiment, a protective structure for the pipe 2 can be realized by covering the pipe 2 with a filling layer 10. Therefore, the pipe protection structure 1 can be realized regardless of whether it is an existing or newly installed pipe, and the pipe protection method 100 has high workability.

[0033] Furthermore, according to the above embodiment, by providing double protection for the piping 2 with the protective sheet 4 and the filling layer 10, the lifespan of the protective sheet 4 and the piping 2 can be extended.

[0034] Furthermore, according to the above embodiment, since the upper part of the filling layer 10 in which the pipe 2 is embedded is a region reinforced by the reinforcing member 14, this region can be effectively utilized for other purposes, such as a sidewalk or road.

[0035] Furthermore, according to the above embodiment, since the pipe 2 is surrounded by a resin material, unintended temperature changes inside the pipe 2 (specifically, freezing, etc.) can be suppressed by the heat retention and insulation effect corresponding to the performance of this resin material.
