[0003] When wiring is provided between adjacent spaces through a through hole formed in the wall in this way, it is necessary to prevent foreign matter from entering through the through hole. As an example of such a configuration, a sealing structure (water-stopping structure) is known in which a hollow pipe member is embedded in the through hole, wiring is configured to pass inside the pipe member, and a sealing member is provided between the inner wall of the pipe member and the wiring, thereby preventing the intrusion of fluids such as seawater and rainwater.

In this document, a ring-shaped elastic body is provided to seal the gap between the inner wall of a pipe member embedded in a through hole formed in a wall portion and the wiring arranged inside the pipe member. The ring-shaped elastic body is compressed inside the pipe member along the extension direction of the pipe member, so that the end of the ring-shaped elastic body expands in the radial direction and adheres closely to the inner wall of the pipe member, thereby obtaining a good sealing effect.

[0013] Hereinafter, some embodiments of the present invention will be described with reference to the accompanying drawings. However, the configurations described as the embodiments or shown in the drawings are merely illustrative examples and are not intended to limit the scope of the present invention.

[0014] (Sealed structure) FIG. 1 is a cross-sectional view showing a sealing structure 1 according to an embodiment, and FIG. 2 is an enlarged view of an area A in FIG. 1. The sealing structure 1 is provided on a wall 2 that is a part of a plant building such as a nuclear power plant. The wall 2 is configured to partition adjacent spaces V1 and V2 in which various devices are arranged in the plant building. FIG. 1 illustrates a case in which the wall 2 extends vertically, but it may extend horizontally or be inclined at a predetermined angle. The wall 2 is flat, but may be curved. The spaces V1 and V2 may be indoor spaces located inside the building, or outdoor spaces located outside the building.

[0015] The wall 2 is made of a building material such as concrete, and has a through hole 6 through which the wiring 4 laid out across the spaces V1 and V2 passes. The through hole 6 is opened in a direction substantially perpendicular to the wall 2 having a predetermined thickness D1. A pipe member 8 for protecting the wiring 4 is embedded in the through hole 6 so that no gap is formed between the wall 2 and the surrounding area.

[0016] The pipe member 8 has a substantially cylindrical pipe shape. In FIG. 1, a case where it has a straight shape extending along one direction (hereinafter, appropriately referred to as the "extending direction") is illustrated, but the pipe member 8 may be curved. The pipe member 8 basically has a substantially constant inner diameter d1 and outer diameter d2, but as will be described later, a concave portion 10 where the inner diameter d1 and outer diameter d2 are partially reduced is formed.

[0017] In the internal space 12 inside the pipe member 8, the wiring 4 is arranged over the spaces V1 and V2. The wiring 4 is, for example, an electric wire for transmitting an electrical signal, and in FIG. 1, a plurality of wirings 4 are arranged in a twisted manner. Note that the number and size of the wirings 4 arranged in the internal space 12 may be arbitrary.

[0018] In the internal space 12, a sealing member 16 is provided in the gap between the inner wall of the pipe member 8 and the wiring 4. The sealing member 16 is provided so as to fill the gap between the inner wall of the pipe member 8 and the wiring 4, thereby forming a water stop structure for preventing the intrusion of fluids such as water between the spaces V1 and V2. This sealing member 16 is provided over a first range R1 along the extending direction of the pipe member 8.

[0019] Note that a pair of dam materials 18 are provided at both ends of the first range R1 where the sealing member 16 is provided. As will be described later, when processing the sealing structure 1, the sealing member 16 is formed by solidifying a material having fluidity. Therefore, by providing the pair of dam materials 18, the material having fluidity during processing can be regulated within the first range R1, and the sealing member 16 can be preferably formed.

[0020] The pipe member 8 has a concave portion 10 that is deformed radially inward compared to the periphery over a second range R2 that is narrower than the first range R1 along the extending direction. In the concave portion 10, as shown in FIG. 2, in the second range R2 of the pipe member 8, it has an inner diameter d1´ (<d1) and an outer diameter d2´ (<d2). This concave portion 10 is formed by the sealing structure processing method described later, so that a pressing force is applied radially inward from the inner surface of the pipe member 8 to the sealing member 16 in the second range R2, and a good sealing effect can be obtained.

[0021] (Sealing structure processing method) Next, a sealing structure processing apparatus 30 for processing the sealing structure 1 having the above configuration and a sealing structure processing method performed using the sealing structure processing apparatus 30 will be described. Fig. 3 is a flow chart showing a sealing structure processing method according to one embodiment, Fig. 4 is a schematic diagram of the sealing structure 1' before the sealing structure processing method of Fig. 3 is performed, Fig. 5 is a schematic diagram of the sealing structure 1' corresponding to step S3 of Fig. 3, Fig. 6 is a perspective view of the contact member 32 of Fig. 5, Fig. 7 is a schematic diagram of the sealing structure 1' corresponding to step S4 of Fig. 3, Fig. 8 is a perspective view of the pressing member 34 of Fig. 7, and Fig. 9 is a schematic diagram of the sealing structure processing apparatus 30 corresponding to step S6 of Fig. 3.

[0022] As shown in Fig. 4, the sealing structure 1' before the sealing structure processing method is performed differs from the sealing structure after the above-mentioned sealing structure processing method is performed (see Figs. 1 and 2) in that the recess 10 is not formed and sufficient pressing force is not applied to the sealing member 16 provided inside the tubular member 8. In this initial state, the tubular member 8 has an inner diameter d1 and an outer diameter d2 throughout.

[0023] 4, in the sealing structure processing method, first, a first area R1 in which the sealing member 16 is provided inside the pipe member 8 in the sealing structure 1' is identified (step S1). The identification of the first area R1 in step S1 may be performed, for example, by referring to the work history or design information when manufacturing the sealing structure 1', or by conducting a prior investigation of the area in which the sealing member 16 is provided.

[0024] 4, a second range R2 narrower than the first range R1 specified in step S1 is set for the pipe member 8 (step S2). This second range R2 is set as a range in which the recess 10 is to be formed.

[0025] 5, the abutment member 32 is placed so as to contact the outer surface of the pipe member 8 in the second range R2 set in step S2 (step S3). In step S3, the abutment member 32 is placed along the circumferential direction of the pipe member 8 in the second range R2 (placed so as to contact the outer surface of the pipe member 8 over the entire circumference of the pipe member).

[0026] 6, the abutment member 32 includes a plurality of piece members 32a, 32b, ... arranged along the circumferential direction. These plurality of piece members 32a, 32b, ... are independent members, and are arranged at approximately equal intervals when they are arranged along the circumferential direction on the outer surface of the pipe member 8 so that there are no gaps between adjacent members. At this time, each piece member 32a, 32b, ... arranged along the circumferential direction on the outer surface of the pipe member 8 may be temporarily fixed using an auxiliary material such as masking tape (each temporarily fixed piece member 32a, 32b, ... is permanently fixed by arranging a pressing member 34 described later on the radial outside).

[0027] Incidentally, each of the piece members 32a, 32b, ... arranged along the circumferential direction on the outer surface of the pipe member 8 can be appropriately detached from the pipe member 8 by removing the auxiliary material for temporary fixation or the pressing member 34. Therefore, the abutment member 32 can be attached to the pipe member 8 by wrapping the plurality of piece members 32a, 32b, ... around it along the circumferential direction without cutting the pipe member 8 to be attached.

[0028] The contact member 32 has a first inclined surface 33c1 and a second inclined surface 33c2 that are located on the opposite side to the first surface 33a, which is a substantially flat surface capable of contacting the outer surface, and are formed so that the thickness of each of the first inclined surface 33c1 and the second inclined surface 33c2 decreases from the center portion 33b toward both ends in the extension direction. In other words, the contact member 32 has a wedge shape.

[0029] 7, the pressing member 34 is disposed so as to come into contact with the contact member 32 disposed in step S2 from the radially outer side (step S4). In this embodiment, the pressing member 34 includes a first ring portion 34a that comes into contact with the first inclined surface 33c1 of the contact member 32 from the radially outer side along the circumferential direction, and a second ring portion 34b that comes into contact with the second inclined surface 33c2 of the contact member 32 from the radially outer side along the circumferential direction.

[0030] 8, each of the first ring portion 34a and the second ring portion 34b is configured by combining half ring members 36a and 36b that are connected to each other via a dividing surface 35 along the radial direction. This allows the first ring portion 34a and the second ring portion 34b to be appropriately attached to the abutment member 32 that abuts against the outer surface of the pipe member 8 along the circumferential direction.

[0031] In step S4, the first ring portion 34a and the second ring portion 34b may be attached so that the dividing surfaces 35 of the first ring portion 34a and the second ring portion 34b are at different circumferential positions. For example, the first ring portion 34a and the second ring portion 34b are attached so that the dividing surfaces 35 of the first ring portion 34a and the second ring portion 34b are at circumferential positions shifted by 90 degrees from each other. This allows the reaction force that the first ring portion 34a and the second ring portion 34b receive from the abutting member 32 to be continuous. This allows the pressing force to be evenly applied to the pipe member 8 via the abutting member 32, and the recesses 10 can be formed in the pipe member 8 with good quality.

[0032] Next, the interval d3 along the extension direction of the first ring portion 34a and the second ring portion 34b arranged in step S4 is reduced (step S5), and as shown in FIG. 9, a pressing force is applied to the abutting member 32 to form a recess 10 in the second range R2 of the pipe member 8 (step S6). As described above, the first ring portion 34a and the second ring portion 34b are in contact with the first inclined surface 33c1 and the second inclined surface 33c2 of the abutting member 32, respectively. Therefore, when the interval d3 between the first ring portion 34a and the second ring portion 34b is reduced, the abutting member 32 is pressed down toward the inside in the radial direction. As a result, the outer surface of the pipe member 8 in contact with the abutting member 32 is plastically deformed by the pressing force acting thereon, and the recess 10 is formed. When the recess 10 is formed in this manner, a pressing force toward the inside in the radial direction is applied to the sealing member 16 inside the pipe member 8 from the inner wall of the pipe member 8.

[0033] In this embodiment, the first ring portion 34a and the second ring portion 34b are connected by a bolt member 37 extending along the extension direction of the pipe member 8. A thread groove is provided on the surface of the bolt member 37, and the thread groove fits into a screw hole provided in the first ring portion 34a and the second ring portion 34b. Therefore, the interval d3 can be adjusted by rotating the bolt member 37. One end of the bolt member 37 is regulated by a nut 38.

[0034] Incidentally, the driving force for rotating the bolt member 37 when adjusting the interval d3 may be applied manually, or as shown in FIG. 10, a hydraulic jack 40 may be used. FIG. 10 is a modified example of FIG. 9. In this modified example, a hydraulic jack 40 is mounted as a power source for driving the bolt member 37. The hydraulic jack 40 is capable of outputting a driving force to the bolt member 37 by supplying hydraulic oil as a working medium to a working space 46 defined by a cylinder 42 and a piston 44, thereby changing the volume of the working space 46. By mounting the hydraulic jack 40 as a power source in this manner, the pressing force for forming the recess 10 can be easily obtained by operating the bolt member 37 with a large driving force. Instead of the hydraulic jack 40, other configurations such as a center hole jack may be used.

[0035] After the recess 10 is thus formed in the pipe member 8, the abutting member 32 and the pressing member 34 may be removed (step S7). The removed abutting member 32 and pressing member 34 can be repeatedly used when forming a recess 10 in another sealing structure 1'. Incidentally, step S7 is optional.

[0036] 11 is a schematic diagram of a sealing structure processing apparatus 30 according to another embodiment. In this embodiment, the pressing member 34 disposed radially outward of the abutting member 32 in step S4 is configured to include an outer peripheral member 34d and a plurality of bolt members 34e. The outer peripheral member 34d is a ring-shaped member disposed radially outward of the abutting member 32 and extending along the circumferential direction of the pipe member 8. In this embodiment, the outer peripheral member 34d is configured by semi-ring-shaped members 34d1 and 34d2 that can be combined with each other. The semi-ring-shaped members 34d1 and 34d2 are configured by connecting flange portions 34d3 provided on each of them using bolts 34d4 and nuts 34d5.

[0037] The bolt members 34e are inserted into a plurality of screw holes formed at predetermined intervals along the circumferential direction of the outer peripheral member 34d in the radial direction. The bolt members 34e have threads and fit into these screw holes. One end of each bolt member 34e protrudes radially inward from the outer peripheral member 34d and abuts against the abutment member 32 from the radially outer side. The amount of protrusion of the bolt members 34e radially inward can be adjusted by rotating the bolt members 34e. In the above-mentioned step S6, the amount of protrusion of the bolt members 34e radially inward is increased substantially uniformly, so that a pressing force is applied to the outer surface of the pipe member 8 via the abutment member 32, and the recesses 10 can be formed.

[0038] As described above, according to each of the above embodiments, by processing the tube member 8 to form the recess 10 using the sealing structure processing device 30, a pressing force is applied to the sealing member 16 inside the tube member 8 in the second range R2 where the recess 10 is formed, and a good sealing effect is obtained.

[0039] In addition, within the scope of the present disclosure, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described embodiments may be combined as appropriate.

The sealing member is provided so as to seal between the inner wall of the pipe member and the wiring, and the pipe member is deformed into a concave shape compared to the surrounding area over a predetermined range. As a result, a compressive force directed radially inward from the pipe member is applied to the sealing member inside the concave portion, thereby obtaining a good sealing effect.

[0043] The above-mentioned configuration may be obtained by forming a recess when a new sealing member is provided in the pipe member, or may be obtained by forming a recess in an existing pipe member in which an enclosing member is already enclosed. In the former case, a new sealing structure with a good sealing effect is obtained. In the latter case, by forming a recess in the pipe member for the enclosing member already provided in the pipe member, a compressive force is applied to the enclosing member inside, thereby making it possible to improve the sealing effect later compared to during construction.

[0044] (2) In another embodiment, in the above embodiment (1), the sealing member is provided over a first range along an extension direction of the pipe member, The recess is formed over a second area narrower than the first area.

[0046] (3) In another embodiment, in the above embodiment (1) or (2), The recess is provided at a position spaced apart from the wall.

[0047] According to the above aspect (3), the recess is provided at a position away from the wall portion. This recess can be formed by processing a pipe member having a uniform diameter, for example, by using a sealing structure processing device described later, and the device can be prevented from interfering with the wall portion during the processing.

[0048] (4) A method for processing a sealing structure according to one embodiment includes the steps of: A pipe member that penetrates the wall portion; Wiring passing through the inside of the pipe member; a sealing member that seals a gap between an inner wall of the pipe member and the wiring; A sealing structure processing method for processing a sealing structure comprising: a step of disposing a contact member on a radially outer side of a predetermined range of the tubular member so as to contact an outer surface of the tubular member; a step of disposing a pressing member radially outward of the contact member; applying a pressing force to the contact member via the pressing member; Equipped with.

In this method, a contact member is arranged so as to contact the outer surface of a tube member having a substantially uniform diameter over a predetermined range. Then, a pressing force is applied to the contact member by a pressing member arranged radially outward. As a result, a recess is formed over a predetermined range of the tube member, and a pressing force is applied to the sealing member inside the recess, thereby obtaining a good sealing effect.

[0050] (5) In another embodiment, in the above embodiment (4), The method further includes the step of removing the contact member and the pressing member.

[0051] According to the above aspect (5), the contact member and the pressing member used for forming the recess may be appropriately removed after the recess is formed, so that the contact member and the pressing member can be reused repeatedly.

[0052] (6) A sealing structure processing apparatus according to one embodiment includes: A pipe member that penetrates the wall portion; Wiring passing through the inside of the pipe member; a sealing member that seals a gap between an inner wall of the pipe member and the wiring; A sealing structure processing apparatus for processing a sealing structure comprising: an abutting member capable of abutting against a predetermined area of ​​an outer surface of the pipe member; a pressing member capable of applying a pressing force from a radially outer side to the abutting member abutting against the pipe member; Equipped with.

[0053] According to the above aspect (6), the sealing structure according to each of the above aspects can be suitably processed using the device. In a predetermined range of a pipe member having a substantially uniform diameter to be processed, a contact member is arranged so as to contact the outer surface of the pipe member. Then, a pressing force is applied to the contact member by a pressing member arranged radially outward. As a result, a recess is formed in the predetermined range of the pipe member, and a pressing force is applied to the sealing member inside the recess, thereby obtaining a good sealing effect.

[0054] (7) In another embodiment, in the above embodiment (6), The abutment member includes a plurality of piece members arranged along a circumferential direction of the pipe member when the abutment member is abutted against the outer surface.

[0055] According to the above aspect (7), the abutment member that is brought into contact with the outer surface of the pipe member includes a plurality of piece members. With this, for example, the abutment member can be attached to the pipe member by arranging the piece members in the circumferential direction with respect to the outer surface of the pipe member without cutting the pipe member at the location where the abutment member is to be disposed.

[0056] (8) In another embodiment, in the above embodiment (6) or (7), The abutment member has a first inclined surface and a second inclined surface that are located on the opposite side to a first surface that can abut against the outer surface and are formed so that their thicknesses decrease from a center portion toward both ends in the extension direction, The pressing member is a first ring portion that abuts against the first inclined surface from a radially outer side along a circumferential direction; a second ring portion that abuts against the second inclined surface from a radially outer side along a circumferential direction; Including, The pressing force is applied to the contact member by reducing the distance between the first ring portion and the second ring portion in the extending direction.

[0059] According to the above aspect (9), the first ring portion and the second ring portion that contact the contact member from the radially outer side are configured by combining anti-ring members that are connected to each other via a dividing surface. This makes it possible to suitably attach each ring portion to the contact member that contacts the outer surface of the pipe member.

[0060] (10) In another embodiment, in the above embodiment (9), The dividing surfaces of the first ring portion and the second ring portion are positioned at different angles from each other on a cross section intersecting the extending direction.

[0061] According to the above aspect (10), by making the positions of the dividing surfaces of the ring parts different, it is possible to make the reaction force that each ring part receives from the contact member continuous. This makes it possible to suitably apply a pressing force to the pipe member via the contact member and form a recess in the pipe member.

[0062] (11) In another embodiment, in the above embodiment (8) or (9), The interval can be adjusted by using a driving force from a hydraulic jack installed on a bolt member connecting the first ring portion and the second ring portion.

[0063] According to the above aspect (11), by transmitting the driving force from the hydraulic jack to the first ring portion and the second ring portion via the bolt member, a large pressing force can be applied from the abutment member to the outer surface.
