Summary of the Invention

Problems to be Solved by the Invention

[0004] It is difficult to identify the location where water leakage occurs, such as on the ceiling of the station concourse or the underground passage of the station. Therefore, there is a need to install water leakage treatment devices such as curing sheets for a long time. In addition, water leakage is not necessarily eliminated by repair. Even if the water leakage stops once, it is sometimes found that the water leakage occurs again after a while, resulting in an intermittent water leakage phenomenon.

[0005] Therefore, when an operator checks the water leakage location, even if it is confirmed that the water leakage outflow has been eliminated, there is a possibility that the water leakage has stopped temporarily. Therefore, the curing sheet is not removed immediately, and the water leakage treatment device is installed for a while and the situation is continuously observed. As a result, the installation of the curing sheet and the like for a long time is required, and it becomes even more difficult to determine when to end the installation.

[0006] Therefore, after installing devices such as a curing sheet, it is required to be able to easily confirm the elimination of water leakage and the like.

Means for Solving the Problem

[0007] A liquid receiving sheet (e.g., a curing sheet) that can be freely installed on a ceiling, wall surface, etc., and a tubular member (such as a flexible hose or pipe) whose end is connected to the discharge port of the liquid receiving sheet can be configured as an instrument that constitutes a set of liquid leakage treatment instruments. The liquid leakage detection instrument is configured to be removably connected to the tubular member and can be incorporated into a set of liquid leakage treatment instruments as needed.

[0008] The installation method of the liquid receiving sheet and the tubular member can be determined according to the location of the water leakage, etc. For example, it can be attached and fixed to the ceiling, wall surface, etc. with tape or the like. The liquid leakage detection instrument can be arranged at a visible position according to their installation.

[0009] The liquid leakage detection instrument of the present invention includes an inflow portion into which liquid flows, a bag body capable of storing the liquid flowing in from the inflow portion, and an outflow portion for discharging the stored liquid (hereinafter referred to as the stored liquid). For example, the inflow portion can be connected to a sheet-side tubular member, and the bag body is configured to be able to store the inflowing liquid instead of allowing it to flow out as it is.

[0010] And the bag body is configured to make the stored liquid visible. The configuration of the bag body for making the stored liquid visible is various. For example, the bag body can be made transparent or translucent so that water leakage, etc. can be visually recognized. Also, the bag body can be configured with various materials. For example, it can be configured with a material (such as vinyl chloride) that can change its shape according to the amount and accumulation condition of the stored liquid. The shape of the bag body is arbitrary. For example, it can be configured as a horizontally long rectangular shape or a rectangular parallelepiped based on a square shape. The bag body can be configured such that the whole or a part is exposed. On the other hand, within the range where the stored liquid can be visually recognized, it may be housed in a case or covered with a member that can make the stored water visible.

[0011] The bag body can store liquids such as leaked water flowing in, and can be configured to be discharged from the outflow part according to the passage of time, the amount of leaked liquid, etc. For example, when the stored liquid exceeds a predetermined amount, the bag body can be configured such that the stored liquid is discharged from the outflow part. With the sheet-side tubular member and the inflow part connected, a storage space region can be formed in the internal space of the bag body so that when the stored liquid is below a predetermined amount, it does not flow downward from the outflow part.

[0012] The bag body can be configured to be provided with an inflow part and an outflow part at the upper part and the bottom part of the bag body, respectively. The bag body only needs to have a sealing property so that the stored liquid does not leak out from other than the outflow part. The end part of a tubular member such as a flexible hose or pipe (hereinafter referred to as the discharge-side tubular member) that can be connected to the outflow part, or the outflow part, can be configured to be located at a predetermined height above the bottom of the bag body. For example, the position (height) of the end part of the discharge-side tubular member inserted into the internal space of the bag body can be determined according to the liquid volume of the stored liquid. For example, the outflow part can be provided at a position deviated from the position opposite to the inflow part.

[0013] It is possible to provide a fastener (chuck) for opening and closing the bag body so that the stored liquid can be discharged. For example, the fastener can be provided between the inflow part and the outflow part of the bag body. When the bag body is a rectangular parallelepiped, the fastener can be provided along the horizontal direction. The configuration of the fastener is various. For example, it can be configured as a close-contact type wire fastener in which a convex strip part is fitted into a concave part.

[0014] The bag body can be provided with a scale indicating the degree of storage of the stored liquid. The notation of the scale is various. For example, a plurality of lines can be arranged in the vertical direction (depth direction) along the liquid surface.

[0015] A set of leak liquid treatment instruments according to one aspect of the present invention includes the above leak liquid storage detection instrument, a liquid receiving sheet that can be installed according to the leak location, a sheet-side tubular member that connects the inflow part of the leak liquid detection instrument and the discharge port of the liquid receiving sheet, and a discharge-side tubular member that connects to the outflow part of the leak liquid detection instrument.

[0016] One installation method of a liquid leakage treatment device set according to an aspect of the present invention is to install a liquid receiving sheet according to the liquid leakage location, connect one end of a sheet-side tubular member to the discharge port of the liquid receiving sheet, and connect the liquid leakage detection device to the other end of the sheet-side tubular member.

Effect of the Invention

[0017] According to the present invention, after installing devices such as a curing sheet, it is possible to easily confirm the elimination of water leakage and the like.

Embodiment for Carrying Out the Invention

[0019] Hereinafter, with reference to the drawings, a set of water leakage treatment devices according to this embodiment will be described.

[0020] A set of water leakage treatment devices is a set of devices that temporarily guide water leakage to a drainage ditch, a bucket, etc. when rain leakage occurs on the ceiling C, wall surface M, etc. inside a station building or an underground passage, and includes a water leakage detection device 10, a curing sheet 100, and pipes 120, 130. The curing sheet 100 is composed of a flexible sheet made of, for example, synthetic resin and can be attached to the ceiling C. A connection pipe 110 for discharging water leakage is provided at the central portion of the curing sheet 100.

[0021] The pipe 120 can be connected to the connection pipe 110 provided on the curing sheet 100, and the water leakage received by the curing sheet 100 flows out to the pipe 120 through the discharge port 110N of the curing sheet 100. The pipes 120, 130 are composed of flexible pipes made of, for example, vinyl chloride here and can be attached to and fixed to the ceiling C or the wall surface M with tape or the like.

[0022] The water leakage detection device 10 is disposed between the pipes 120 and 130, temporarily stores the water leakage flowing into the pipe 120, and discharges the stored water leakage to the pipe 130. The pipe 240 is also made of a flexible material like the pipe 120, can be attached to and fixed on the wall surface M.

[0023] When the operator finds the water leakage location, the operator transports and installs the set of water leakage treatment devices to the water leakage site. Specifically, the curing sheet 100 is attached to the ceiling C or the wall surface M with tape or the like so as to cover the water leakage location. Also, one end 120A of the pipe 120 is connected to the connection pipe 110 of the curing sheet 100, and the other end 120B of the pipe 120 is connected to the water leakage detection device 10. Further, one end 130A of the pipe 130 is connected to the water leakage detection device 10, and the other end 130B is disposed in a bucket or a drainage ditch or the like.

[0024] FIG. 2 is a plan view of the water leakage detection device 10 as viewed from the front side. FIG. 3 is a side view of the water leakage detection device 10.

[0025] The water leakage detection device 10 includes a bag body 40 capable of storing water leakage. The bag body 40 is made of a flexible material and has a three-dimensional shape with a depth (length) and a width. On the other hand, in a state where no water leakage flows in, it has a shriveled shape. Here, the bag body 40 uses vinyl chloride as the material. The bag body 40 has a shape in which a rectangular parallelepiped shape is recessed from both side surfaces in a state where no water leakage is contained, and deforms when a force is applied by hand.

[0026] The shape of the bag body 40 changes according to the amount of water leakage stored in the internal space S. As the storage amount increases, it changes from a shriveled shape to a rectangular parallelepiped shape. Note that FIGS. 2 and 3 show the shape when the internal space S of the bag body 40 is filled with liquid.

[0027] The bag body 40 is provided with an inflow part 20 at the upper part 40U and an outflow part 30 at the bottom part 40B. When the end part 120B of the pipe 120 is inserted into the inflow port 20A of the inflow part 20, the pipe 120, the water leakage detection device 10, and the internal space S of the bag body 40 are spatially connected.

[0028] The outflow part 30 of the water leakage detection device 10 is provided on the inflow part 20 side (upper side) rather than the bottom part 40B of the internal space S of the bag body 40, and is formed so as to straddle the concave part 40K formed near the bottom corner of the bottom part 40B of the bag body 40 and the internal space S. While the inflow part 20 is provided along the center line (see reference sign C) of the bag body 40, the formation position of the outflow part 30 is deviated from the position along the center line C, that is, the position facing the inflow part 20. Here, the inflow part 20 and the outflow part 30 are made of the same material as the bag body 40.

[0029] The end part 130A of the pipe 130 is screwed with the male screw formed on the inner surface 30N of the tubular outflow part 30 and is fixed in a shape protruding upward from the outflow part 30 (see FIG. 1). In the bag body 40, the end part 130A of the pipe 130 is fixed at a position of a predetermined height h from the bottom part 40B of the bag body 40.

[0030] On the surface side of the bag body 40, a fastener 42 is provided along the lateral direction (longitudinal direction) of the bag body 40. The fastener 42 can be opened and closed so as to be able to discharge the stored water leakage, and seals the internal space S so that the stored water does not leak out in the closed state. Here, the fastener 42 is constituted by an adhesive surface fastener that fits a convex strip and a concave strip and is integrally formed with the bag body 40.

[0031] The exposed bag body 40 is colorless and transparent here, and the stored water can be visually recognized. Further, on the surface side of the bag body 40, a scale 50 indicating the degree of the stored amount of the stored water is provided. Here, scales arranged at a predetermined interval in the depth direction (vertical direction) are marked, printed, etc. between the fastener 42 of the bag body 40 and the bottom part 40B of the bag body 40.

[0032] By arranging such a water leakage detection device 10 between the pipes 120 and 130, it is possible to confirm whether water leakage has occurred before after installing the set of water leakage treatment devices.

[0033] In the case of water leakage in the underground structure of the station, it is difficult to identify the water leakage source and to confirm the repair effect. Therefore, there are cases where a set of water leakage treatment devices is installed as it is for a long period (for example, several months to several years). Also, water leakage does not always flow out continuously, and it may occur intermittently and irregularly. On the other hand, it is practically impossible for the operator to constantly monitor the water leakage situation.

[0034] As described above, the water leakage detection device 10 can store water leakage in the internal space S until the amount of stored water exceeds a certain amount, that is, until it reaches the end 130A of the pipe 130 inserted into the outflow part 30 and reaching into the internal space S of the bag body 40. That is, by installing the water leakage detection device 10 with the inflow part 20 on the upper side and the outflow part 30 on the lower side, a storage space is formed between the end 130A of the pipe 130 and the bottom 40B of the bag body 40. In FIG. 1, the stored water is indicated by the symbol W.

[0035] Since the outflow part 30 is displaced from the position facing the inflow part 20, it is possible to prevent the inflowing water leakage from flowing out from the outflow part 30 as it is. Also, since the outflow part 30 is connected and fixed to the pipe 130 by screwing, the outflow part 30 and the pipe 130 are in close contact, and the position of the end 130A of the pipe 130 can be adjusted, that is, the height h from the bottom 40B of the bag body 40 can be adjusted.

[0036] As described above, since the stored water detection device 10 is transparent so that water leakage can be visually recognized, the stored water leakage can be visually recognized. Even if water leakage occurs intermittently and irregularly, the operator can confirm that the water leakage has not been eliminated yet by checking the stored water leakage.

[0037] In addition, the operator can check the amount of accumulated water leakage by means of the scale 50. By quantitatively measuring the amount of accumulated water leakage based on the scale 50 each time the inspection operation is performed, it is possible to know whether the water leakage has stopped (no accumulated water is confirmed, no change in the amount of water leakage, etc.) or the water leakage has not been eliminated (accumulated water is confirmed, increase in the amount of water leakage).

[0038] For example, in a situation where an existing set of water leakage treatment devices whose installation time cannot be confirmed is installed, by installing the water leakage detection device 10 together with the pipes 120 and 130, it is possible to check whether the water leakage has been eliminated, and it becomes possible to remove the curing sheet that has been installed for a long time.

[0039] On the other hand, when the accumulated water leakage exceeds a certain amount, the accumulated water flows out from the outflow part 30, and the internal space S of the water leakage detection device 10 will not be filled with water leakage, thus suppressing the leakage of the accumulated water. Therefore, the water leakage detection device 10 can control the flow of water leakage like a weir.

[0040] Furthermore, by opening and closing the fastener 42, the accumulated water leakage can be discharged without removing the water leakage detection device 10. Thereby, the water leakage mixed with rust juice and the like can be discharged.

[0041] The bag body 40 has the airtightness that the stored water leakage does not leak out, and the bag body 40 is made of a flexible material, and it is possible to determine the installation height and posture (tilt) according to the installation location of the set of water leakage treatment devices. In particular, since the pipes 120 and 130 are flexible members, the operator can arrange the water leakage detection device 10 at a desired position according to the water leakage location. Therefore, the posture of the bag body 40 does not necessarily maintain the horizontal method in the horizontal direction and may be tilted. However, due to the structure of the bag body 40 that has flexibility and enables the storage of a certain amount of accumulated water, the water leakage detection function can be exerted regardless of the arrangement location and position (posture).

[0042] The shape characteristics, materials, etc. of the bag body 40 are not limited to the above-mentioned shape characteristics and materials. Regarding the connection configuration between the outflow part 30 and the pipe 130, it may also be configured such that the outflow part 30 is on the upper side and the end 130A of the pipe 130 is on the lower side for connection. Furthermore, the bag body 40 can also be configured separately from the inflow part 20 and the outflow part.

[0043] The bag body 40 can also be semi-transparent. It may be made of a permeable material that allows the stored water to be confirmed. For example, it may be made of a permeable material with a color that makes rust juice, etc. less visible. Furthermore, only a part of it may be made transparent. As long as the stored water can be visually recognized.

[0044] In the above-mentioned bag body 40, when the stored water exceeds a certain amount, it is configured to flow out naturally according to gravity, but it may also be configured to be partitioned so that the stored water does not flow out and to flow out from the bag body 40 when a pressure above a certain level is applied.

[0045] The above-mentioned leakage detection device 10 is also applicable to the ceilings, walls, etc. of buildings other than inside the station building and underground passages. For example, it is also applicable to hospitals, buildings, factories, agricultural facilities such as greenhouses, and transportation containers. Furthermore, it can also be used in situations where liquids other than leakage leak out.
