Hereinafter, a storage device 10 and a drainage system S according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, first, the conduit 100 constituting the drainage system S will be briefly described, and then the configuration of the storage device 10 connected to the conduit 100 will be described in detail. In addition, in the following description, unless otherwise specified, the positional relationships such as vertical, horizontal, etc. will be explained based on a state in which the storage device 10 and the drainage system S are installed so that they can be used in a normal usage mode.

≪About the overview of the drainage system S≫

The drainage system S shown in FIG. 1 discharges wastewater discharged from the drainage equipment 3 toward the downstream side of the sewage main pipe 4 and the like. Specifically, the drainage system S operates when the water supply to the drainage equipment 3 is functioning (water supply function) and when the drainage to the sewage main pipe 4 is functioning (drainage function). (time), the wastewater discharged from the drainage equipment 3 can be discharged toward the downstream side of the sewage main pipe 4 and the like. In addition, the drainage system S can be used when the water supply to the drainage equipment 3 has stopped due to a disaster such as an earthquake (water outage), or when a temporary toilet is installed in an outdoor location or other location where water supply equipment is insufficient. If the water supply function is insufficient due to the installation of a water supply system (water supply is not possible), stored water can be supplied to a pipe line 100, which will be described later, and wastewater can be discharged to the downstream side. Furthermore, when a part of the sewage main pipe 4 or the pipe 100 is damaged and it is difficult to drain the sewage to the sewage main pipe 4 (drainage is impossible), the drainage system S transfers the sewage to a sewage storage tank. 190 can be discharged. That is, when water cannot be supplied and drainage is not possible (when supply and drainage are not possible), the drainage system S supplies stored water to drain the sewage into the pipe 100 and drains the sewage discharged from the drainage equipment 3 into sewage. It can be discharged toward the storage tank 190.

Here, the sewage main pipe 4 is a pipe that leads sewage to a sewage treatment plant (not shown). Sewage flowing out from the drainage equipment 3 of the building 1 is normally discharged into the sewage main pipe 4. Further, the above-mentioned drainage equipment is equipment for discharging sewage. Drainage facilities include, for example, a toilet, bath, or kitchen sink. In addition, the drainage equipment installed in the drainage system S includes, in addition to the existing drainage equipment such as toilets and baths already installed in the building 1 (existing drainage equipment 3a), temporary drainage equipment such as temporary toilets ( There is a temporary drainage facility 3b). Further, the building 1 includes a residence, a commercial facility, a factory, a school building, a warehouse, and the like.

≪About conduit 100≫

As shown in FIG. 1, the conduit 100 has a main pipe 110 and a standpipe 120, and constitutes a passage through which water flows underground. In the present embodiment, the pipe line 100 is formed by connecting a plurality of pipe materials, joints, etc. to form a drainage flow path C that serves as a flow path for wastewater.

In the pipe line 100, the main pipe 110 constitutes a flow path extending from the upstream side to the downstream side (the side of the main sewage pipe 4). Although the main pipe 110 may be constituted by a single pipe line, in this embodiment, it is provided with a first pipe line 110a and a second pipe line 110b. Further, in the conduit 100, a plurality of standpipes 120 are provided. A storage device 10, which will be described in detail later, is connected to the conduit 100, and a switchable drainage mass 150, a backflow prevention mass 170, and the like are arranged.

The first pipe line 110a is provided from the storage device 10 to the main sewer pipe 4. Further, the second pipe line 110b is provided so as to extend from the switchable drainage mass 150 to the wastewater storage tank 190. The main pipe 110 is capable of forming two systems as a wastewater drainage flow path C by a first pipe line 110a and a second pipe line 110b. Specifically, the main pipe 110 includes a first flow path c1 that discharges wastewater to the main sewer pipe 4 via the first pipe line 110a, and a second flow path c1 that discharges wastewater to the wastewater storage tank 190 via the second pipe line 110b. It is possible to form two channels c2.

In other words, the main pipe 110 can form the first flow path c1 as a normal drainage flow path C for discharging wastewater into the main sewage pipe 4 through the first flow path c1. In addition, the main pipe 110 is used when discharge is impossible, such as when the main sewage pipe 4 or the first pipe line 110a downstream of the branch part with the second pipe line 110b is damaged, and there is a risk that the wastewater will flow back upstream. As the drainage flow path C, a second flow path c2 that discharges wastewater to the wastewater storage tank 190 can be formed.

The standpipe 120 constitutes the conduit 100 similarly to the main pipe 110. The standpipe 120 is installed upright so as to communicate with the piping that constitutes the main pipe 110. For example, the standpipe 120 is connected to the main pipe 110 via a drainage mass 147 provided in the conduit 100, and is erected toward the ground. The standpipe 120 may be connected to the conduit 100 via a joint instead of being provided in the drainage mass. Moreover, the drainage mass in which the standpipe 120 is provided can be selected from various types, such as a sewage mass, a rainwater mass, etc.

The standpipe 120 is a pipe buried underground. The standpipe 120 has a lower end connected to the first conduit 110a, and is erected toward the ground. The standpipe 120 has an opening 122 at its upper end. The opening 122 functions as an inspection port for inspecting the inside of the conduit 100 from the ground side. The opening 122 is closed by the lid 130 during normal times other than disasters. In a situation where the temporary drainage equipment 3b is installed such as in the event of a disaster, the temporary drainage equipment 3b can be attached to the upper end of the standpipe 120 by removing the lid 130 as shown in FIG.

Although FIG. 1 shows an example in which the temporary drainage equipment 3b is installed in the standpipe 120 installed downstream of the existing drainage equipment 3a, the temporary drainage equipment 3b is installed in the standpipe 120 installed downstream of the existing drainage equipment 3a. It may be provided in the standpipe 120. For example, if a standpipe 120 is provided upstream of the existing drainage facility 3a and downstream of the storage device 10, the temporary drainage facility 3b may be provided in the standpipe 120.

The lid 130 is fitted into the opening 122 of the standpipe 120 to close the upper end of the standpipe 120. The shape and material of the lid 130 can be selected as appropriate as long as it can close the opening 122. In this embodiment, the lid body 130 is a so-called parent-child lid. Specifically, as shown in FIGS. 2 and 3, the lid body 130 includes a lid frame 132, a main lid 134, and a child lid 136.

The parent lid 134 has a parent lid main body 138 and a cylindrical portion 142. The parent lid main body 138 is a portion that fits into the lid frame 132. A fitting hole 140 is formed in the parent lid main body 138 and extends vertically. An annular main lid sealing member 138a is attached to the main lid main body 138, which contacts the lid frame 132 when the main lid 134 is fitted into the lid frame 132. The structure is designed to improve sealing performance when fitted.

The cylindrical portion 142 is a cylindrical portion extending downward from the main lid main body 138. The cylindrical portion 142 is provided in the parent lid main body 138 so as to surround the fitting hole 140 when viewed from the bottom. In this embodiment, the cylindrical portion 142 extends downward from the edge of the fitting hole 140 in the parent lid main body 138. Note that the cylindrical portion 142 may have one or more slits formed therein. Further, in this embodiment, the parent lid main body 138 and the cylindrical portion 142 are integrally molded, but they may be separate bodies.

The child lid 136 is a lid member that fits into a fitting hole 140 formed in the main lid main body 138 of the main lid 134 . The child cover 136 has a shape corresponding to the fitting hole 140. In this embodiment, since the fitting hole 140 has a circular opening, the child lid 136 has a disk shape. The child lid 136 is attached with an annular child lid sealing member (not shown) that comes into contact with the main lid main body 138 when the child lid 136 is fitted into the main lid 134. The structure is such that the sealing performance is improved when the main cover 134 is fitted.

≪About the storage device 10≫

As shown in FIG. 1, the storage device 10 is connected to a pipe line 100 that constitutes a drainage channel through which wastewater flows. While the pipeline 100 described above is buried underground, the storage device 10 is installed above ground. As shown in FIGS. 2 and 3, the storage device 10 includes a storage section 20, a projecting section 30, a discharge section 40, a plug section 50, and an operation section 60.

The storage section 20 has a storage space inside which can store water. The storage section 20 can be configured by selecting appropriate size, shape, material, etc. The storage section 20 is preferably made of a resin material such as vinyl chloride resin, polypropylene resin, fiber-reinforced plastic, or the like. Furthermore, when the storage section 20 is made of vinyl chloride resin, hard vinyl chloride resin can be suitably used.

The storage section 20 has a bottomed cylindrical shape with an open upper end and a bottom 22 at the lower end. A discharge port 42 of a discharge section 40, which will be described in detail later, is opened at the bottom 22 of the storage section 20. The storage section 20 may have the discharge port 42 located at any position on the bottom section 22, but in this embodiment, the outlet port 42 is opened at approximately the center of the bottom section 22 (approximately at the axial center position of the storage section 20). It is set up in The bottom portion 22 is formed to have a downward slope toward the discharge port 42. Therefore, the bottom portion 22 of the storage portion 20 is formed into a mortar shape (tapered shape).

The projecting portion 30 is a portion extending outward from the outer circumferential surface of the storage portion 20 . The projecting portion 30 extends so as to come into contact with the installation surface (in this embodiment, the ground) on which the storage portion 20 is installed, when the storage portion 20 is installed. Thereby, in the storage device 10, the storage section 20 can be stably installed on the installation surface by the overhang section 30. The projecting parts 30 may be, for example, leg-shaped parts provided at predetermined intervals in the circumferential direction of the storage part 20; It is said to be of a type. Thereby, the projecting portion 30 is able to stably support the storage portion 20 over the entire circumference.

The discharge section 40 is for discharging the water stored in the storage section 20. The discharge part 40 is a part connected to an opening 122 provided at the upper end of the standpipe 120. The discharge section 40 is provided at the bottom 22 of the storage section 20. The discharge section 40 has a discharge tube 44 having a discharge port 42 opened inside the storage section 20 . As described above, the discharge port 42 is formed to open at the bottom 22 of the storage section 20.

The discharge tube 44 is a cylindrical portion formed to protrude further downward from the discharge port 42 of the storage section 20 . The discharge pipe 44 (discharge part 40) may be formed as a separate member from the storage part 20 described above and attached to the storage part 20, but in this embodiment, it is formed integrally with the storage part 20. There is. The discharge pipe 44 is formed to protrude further downward than the bottom 22 of the storage section 20 and the lower end of the projecting section 30. Therefore, when the storage section 20 is installed on the installation surface (ground), the discharge tube 44 is formed so as to reach below the installation surface.

The discharge part 40 is formed of a cylindrical body having a size that can be inserted into the opening 122 of the standpipe 120 described above. In this embodiment, the size (outer diameter) of the discharge part 40 is adjusted according to the size of the fitting hole 140 that is opened by removing the child cover 136 of the cover body 130 provided in the opening 122 of the standpipe 120. is set. Therefore, in the storage device 10, the child cover 136 of the cover body 130 provided at the opening 122 of the standpipe 120 is removed, and the cylindrical body forming the discharge part 40 is inserted into the fitting hole 140 for communication. It can be connected to the opening 122 .

The plug part 50 is for opening and closing the discharge part 40. The plug part 50 is arranged inside the storage part 20. The plug part 50 can open and close the discharge part 40 by moving in a predetermined direction (the axial direction of the storage part 20, the vertical direction). The plug portion 50 includes a first plug component 52 and a second plug component 54.

The first stopper component 52 is a portion that can enter the inside of the discharge pipe 44 from the discharge port 42 . The first stopper component 52 can open and close the discharge section 40 by entering and leaving the discharge tube 44 . Further, the second plug component 54 is located on the front side of the first plug component 52 in the direction of entry from the discharge port 42 into the inside of the discharge tube 44 . The second stopper component 54 is a portion that cannot enter the discharge pipe 44 from the discharge port 42 . The second stopper component 54 is for suppressing the stopper 50 from entering the discharge pipe 44 excessively. The second stopper component 54 can be formed, for example, by providing a bulge that is more bulged than the first stopper component 52.

In this embodiment, the plug part 50 is connected to the first plug component 52 by providing a connecting member 68 for connecting an operating section 60, which will be described in detail later, to the bottomed cylindrical plug component 56. In addition, a second stopper component 54 is provided.

Specifically, the plug portion 50 can enter the discharge tube 44 with the closed bottom side portion of the plug component 56 leading. The plug component 56 is formed so that its outer diameter substantially matches the inner diameter of the discharge pipe 44 . The first plug component 52 is constituted by a portion of the plug component 56 on the front side in the direction of entry into the discharge pipe 44 (bottom side portion). A plug sealing member 58 is provided around the entire circumference of a portion of the plug portion 50 that corresponds to the first plug forming portion 52 . As a result, the plug part 50 has a high sealing performance when the first plug component 52 of the plug part 50 enters the discharge pipe 44, and ensures that water is discharged through the discharge part 40. It can be suppressed.

The second plug component 54 is provided on the front side (in the illustrated example, on the upper side) of the first plug component 52 in the direction in which the plug portion 50 enters. The second plug component 54 has a portion that bulges out to the outside of the plug component 56 by providing a connecting member 68 for connecting the operating section 60 to the plug component 56 . Specifically, a bolt 68a provided as a connecting member 68 is provided in the second plug component 54 so as to penetrate through the plug component 56 in the radial direction. Therefore, on one radial side of the plug component 56, the head of the bolt 68a is provided so as to bulge out toward the outside of the plug component 56. Further, on the other radial side of the plug component 56, a nut 68b is attached to the shaft portion of the bolt 68a. Thereby, the nut 68b is provided so as to bulge out on the other radial side of the plug component 56. Since the second plug component 54 has a bulge formed by the head of the bolt 68a and the nut 68b, it is impossible to enter the discharge tube 44 from the discharge port 42. Therefore, although the portion of the plug portion 50 corresponding to the first plug component 52 can enter the discharge pipe 44 via the discharge port 42, the portion corresponding to the second plug component 54 gets caught and the discharge pipe 44 Do not enter excessively.

The operating section 60 is provided to move the plug section 50 by operating from the outside of the storage section 20 and to enable a switching operation for switching the open/closed state of the discharge section 40 . In this embodiment, since the plug part 50 can open and close the discharge part 40 by moving in the vertical direction, the operation part 60 can perform an operation to displace the plug part 50 in the vertical direction. The operating section 60 is connected to the plug section 50 and taken out to the outside of the storage section 20 . The operating section 60 can open and close the discharge section 40 by moving the plug section 50 in a predetermined direction by operating from the outside of the storage section 20 . Specifically, the operating section 60 includes an operating rod 62, a grip section 64, and a connecting section 66.

The operating rod 62 is a rod-shaped or cylindrical member. The operating rod 62 has a length that projects upward from the upper end of the storage section 20 when the plug section 50 is placed inside the storage section 20 .

The grip portion 64 is provided on the upper end side of the operating rod 62. The grip part 64 is provided so that the user can easily grip it when operating the plug part 50 using the operation part 60. The shape, size, etc. of the grip portion 64 can be set as appropriate so that it can be easily gripped by the user. In this embodiment, the grip portion 64 is constituted by a rod-shaped or cylindrical member extending in a direction intersecting the axial direction of the operating rod 62 (in the illustrated example, a substantially perpendicular direction).

The connecting portion 66 is a portion connected to the plug portion 50. The connecting portion 66 is provided on the lower end side of the operating rod 62. The connecting portion 66 is constituted by a cylindrical member extending in a direction intersecting with the axial direction of the operating rod 62 (in the illustrated example, a substantially orthogonal direction). Further, the connecting portion 66 has a length that can be accommodated inside the plug component member 56 forming the plug portion 50.

Since the storage device 10 is configured as described in (6) above, when the discharge section 40 is closed, the first plug component 52 forming the plug section 50 enters the discharge pipe 44. On the other hand, the second plug component 54 located on the front side in the entry direction with respect to the first plug component 52 does not enter the discharge pipe 44 . Therefore, the storage device 10 of the present invention can prevent the plug part 50 from entering the discharge pipe 44 excessively when the discharge part 40 is closed. As a result, in the storage device 10 of the present invention, it is difficult for the plug section 50 to penetrate the discharge section 40 and fall off, or for the plug section 50 to be difficult to separate from the discharge section 40 when the discharge section 40 is next opened. You can prevent this from happening.

(7) The drainage system S described above is a storage device that includes a storage section 20 that can store water, a discharge section 40 that discharges water stored in the storage section 20, and a plug section 50 that can open and close the discharge section 40. 10, a main pipe 110 through which sewage flows underground, and a pipe line 100 equipped with a standpipe 120 that is erected to communicate with the main pipe 110 and has an opening 122 that opens upward.

The discharge part 40 can be installed by communicating with the fitting hole 140. Thereby, the drainage system S can be stably installed. Moreover, since the drainage system S is installed by connecting the discharge part 40 of the storage device 10 to the parent-child lid type lid 130, leakage of odor can be suppressed.

≪Modification example≫

Note that the storage device 10 and the drainage system S described above are merely illustrative of one embodiment of the present invention, and the configurations can be changed as appropriate without departing from the spirit of the present invention. For example, the storage device 10 and the drainage system S are not limited to those that include all of the configurations related to (1) to (8) above, but may omit any of these configurations or replace them with other configurations. It is also possible to use

For example, the storage device of the present invention is not limited to the storage device 10 described above, and may be, for example, a storage device 210 shown in FIG. 5. The storage device 210 is configured such that a discharge section 240 is provided on the side surface of the storage section 220 at a position on the bottom section 222 side. The storage device 210 is provided with a plug part 250 that can open and close the discharge part 240.

The storage device 210, like the storage device 10, has the feature (1) described above. That is, the storage device 210 is connected to an existing pipeline 100 that is buried underground and includes a main pipe 110 through which wastewater flows, and a standpipe 120 that is installed upright to communicate with the main pipe 110. It has a storage section 220 that can store water, a discharge section 240 that discharges the water stored in the storage section 220, and a plug section 250 that can open and close the discharge section 240. , can be connected to an opening 122 provided at the upper end of the standpipe 120. In the case of such a configuration, as shown in FIG. By this operation, the water stored in the storage section 220 on the ground can be vigorously discharged toward the pipe line 100 buried underground.

Note that it is preferable that the storage device 210 has the same configuration as the storage device 10 described above. For example, as illustrated with the same reference numerals as the storage device 10 described above in FIG. A structure in which the stopper part 250 is provided with a downward slope toward the discharge part 240, and a structure in which a bulge part is provided to suppress excessive entry of the stopper part 250 into the discharge part 240 like the second stopper component part 54, etc. That's good.

Moreover, although the storage device 10 of the said embodiment is provided with the overhang part 30 like (2) mentioned above, this invention is not limited to this. The storage device 10 may not include the projecting portion 30. Thereby, the configuration of the storage device 10 can be simplified. Furthermore, the storage device 10 may be provided with other configurations for improving the stability of the storage section 20 instead of or in addition to the overhang section 30.

The storage device 10 of the above embodiment has a configuration in which the plug portion 50 disposed inside the storage portion 20 can be operated by the operation portion 60 taken out outside the storage portion 20, as described in (3) above. Instead, other configurations may be adopted. For example, the storage device 10 includes an opening/closing section including a valve or the like that can control the discharge of water on the outside of the storage section 20, and controls the discharge of water from the storage section 20 to the pipe line 100 by operating the opening/closing section. It is also possible to have a configuration that can perform the following.

The storage device 10 of the above embodiment is provided with the discharge section 40 at the bottom 22 of the storage section 20 as described in (4) above, but unlike the storage device 210 according to FIG. It is also possible to have a configuration in which the discharge section 40 is provided at the portion. Note that even when the water storage device 10 is capable of discharging water from a source other than the bottom portion 22, the water head pressure is used to forcefully discharge the water toward the pipe line 100. It is better to have a configuration that allows water to be drained from a nearby location.

Although the storage device 10 of the above embodiment is formed such that the bottom part 22 of the storage part 20 slopes downward toward the discharge part 40 as described in (5) above, the present invention is limited to this. Instead, the bottom portion 22 may be provided substantially horizontally.

The storage device 10 of the above embodiment employs the plug section 50 including the first plug component 52 and the second plug component 54, as described in (6) above, but the present invention is not limited to this. However, the present invention is not limited to this, and it is also possible to not include a portion that cannot enter the discharge pipe 44, such as the second stopper component 54, for example. That is, in the storage device 10, a large pressure acts on the plug portion 50 in the direction of entry into the discharge tube 44, but in the storage device 210 according to the modified example shown in FIG. 5, for example, a large pressure acts on the plug portion 50. Therefore, it is assumed that there is a low possibility that the plug part 250 will excessively enter the discharge part 240 due to the influence of the pressure acting on the plug part 250. Therefore, in such a case, a configuration may be adopted in which the second stopper component 54 is omitted.

In the drainage system S of the above embodiment, water is stored in the storage section 20 by installing the storage device 10 on the ground and connecting the discharge section 40 to the opening 122 of the standpipe 120, as described in (7) above. Although the water can be discharged to the main pipe 110 via the standpipe 120, the present invention is not limited thereto. For example, the drainage system S may include the storage device 210 according to the modification described above instead of the storage device 10.

As described in (8) above, the drainage system S of the above embodiment utilizes a so-called parent-child lid type lid body 130 that includes a parent lid 134 and a child lid 136, and removes the child lid 136 to remove the storage device 10. However, the present invention is not limited to this. The drainage system S may be installed by connecting the discharge pipe 44 to the part from which the main cover 134 is removed. Furthermore, the lid 130 attached to the opening 122 is not limited to a parent-child lid type. When using a lid other than a parent-child lid type as the lid 130, the drainage system S can be constructed by connecting the discharge tube 44 to an opening formed by removing the lid 130.

Further, as shown in FIG. 6, the drainage system S can be configured such that the storage device 10 is attached to a lid body 130 disposed below the ground, such as by providing a protective lid 180. It is. In the case of the configuration shown in FIG. 6, the storage device 10 is provided above the protective lid 180 in the open state, and the child lid 136 of the lid body 130 is removed, and the fitting hole 140 and the discharge tube 44 are connected to each other. It is possible to connect them with a separately provided connecting tube 46. Furthermore, instead of providing the connecting tube 46, the connecting tube 44 can be formed long from the beginning so that it can reach the fitting hole 140 of the lid body 130 provided on the lower side of the protective lid 180. The discharge pipe 44 may be directly connected to the fitting hole 140 without using the pipe 46.

Further, the drainage system S of the above embodiment can be provided with a water conveying device 300 as shown in FIG. 7 . Specifically, the water conveyance device 300 shown in FIG. 7 introduces water discharged from the discharge portions 40 and 240 of the storage devices 10 and 210 into the main pipe 110. The water guide device 300 is a cylindrical member that can be placed inside the standpipe 120. The water conveyance device 300 includes an inflow section 310, a conduit section 320, and an outflow section 330.

The inflow portion 310 is open at one end side of the water guiding device 300. The inflow section 310 is a section that receives water discharged from the discharge sections 40 and 240 of the storage devices 10 and 210. The inflow section 310 is disposed inside the standpipe 120 on the downstream side of the discharge sections 40 and 240. A seal portion 312 is provided on the outer peripheral surface of the water conveying device 300. The seal portion 312 is formed of, for example, an O-ring. Further, the outer diameter of the inflow portion 310 substantially matches the inner diameter of the standpipe 120. Therefore, the inflow portion 310 is in close contact with the standpipe 120 via the seal portion 312.

The pipe section 320 is a part of the water guide device 300 located downstream (on the main pipe 110 side) with respect to the inflow section 310. In the conduit section 320, a portion following the inflow section 310 is a reduced diameter section 322. The diameter-reducing portion 322 is formed to have a tapered shape or the like, as shown in the illustrated example, so that the diameter thereof decreases toward the downstream side. The conduit section 320 may be constituted by a reduced diameter section 322 over its entire length, but in the illustrated example, a cylindrical section 324 whose opening diameter does not change and remains constant in a portion following the reduced diameter section 322 is provided. The inner diameter of the cylindrical portion 324 is smaller than the inner diameter of the inlet portion 310 and the standpipe 120. Therefore, the pipe section 320 can amplify the force of the water flowing in from the inflow section 310.

The outflow portion 330 is a portion opened so that water can flow out from the conduit portion 320. The outflow portion 330 is arranged such that its tube axis is inclined toward the main pipe 110 side than the tube axis of the inflow portion 310. The outflow portion 330 is arranged such that the tube axis direction faces the downstream side of the main pipe 110. The inner diameter and opening diameter of the outflow section 330 can be the same as or larger than the inner diameter of the conduit section 320, but are preferably smaller than the inner diameter of the conduit section 320. By making the inner diameter and opening diameter of the outflow section 330 smaller than the inner diameter of the conduit section 320, the force of water discharged from the outflow section 330 can be further increased.

Note that the drainage system S equipped with the water guiding device 300 described above is merely an example of the present invention, and for example, the water guiding device 350 shown in FIG. 8 may be provided instead of the water guiding device 300. It is possible. As shown in FIG. 8 with the same reference numerals as in FIG. 7, the water conveyance device 350 has the same structure as the inflow section 310 and the outflow section 330, but the conduit section 320 is composed of only the reduced diameter section 322. The difference is that the cylindrical portion 324 is not provided. Such a configuration can be suitably used when a conventionally known drainage mass or switching type drainage mass 150 is used as the standpipe 120 for connecting the storage devices 10, 210.

The drainage system S constructed using the water conveyance device 300 and the water conveyance device 350 described above has the following characteristic configuration (9), so it has the following unique effects that cannot be achieved with the conventional technology. can play.

It is characterized in that it has an outflow section 330 that allows the flow to flow out, and that the tube axis of the outflow section 330 is arranged so as to be inclined toward the main pipe 110 side rather than the tube axis of the inflow section 310.

The drainage system S illustrated in FIGS. 7 and 8 includes water conveying devices 300 and 350 as described above inside the standpipe 120, thereby discharging water discharged from the discharge portions 40 and 240 of the storage devices 10 and 210. It can be received at the inflow section and discharged toward the main pipe 110 via the conduit section 320 and the outflow section 330. In addition, this drainage system S is arranged such that the pipe axis of the outflow section 330 is inclined toward the main pipe 110 side than the pipe axis of the inflow section 310, so that water enters the water conveyance devices 300, 350 from the storage devices 10, 210. The water can be smoothly introduced into the main pipe 110 while directing the water flow in the direction along the main pipe 110. Therefore, this drainage system S can forcefully flow the water discharged from the storage devices 10, 210 into the main pipe 110 via the water guide devices 300, 350, and can further improve the cleaning ability of the main pipe 110. .

It is preferable to provide the storage device 10, 210 in the standpipe 120 (on the opposite side from the sewage main pipe 4). Further, when a plurality of temporary drainage facilities 3b are provided, the drainage system S is configured such that water can be discharged from the storage devices 10 and 210 located upstream of the temporary drainage facilities 3b that discharge wastewater etc. toward the main pipe 110. It is preferable that the storage device 10, 210 corresponding to the temporary drainage facility 3b is provided on the upstream side (on the opposite side from the sewage main pipe 4). Furthermore, in the examples shown in FIGS. 1 and 5, a plurality of temporary drainage facilities 3b are provided for one storage device 10, 210, but the present invention is not limited to this, and the temporary drainage facilities 3b and The storage devices 10 and 210 are provided in a pair, and the temporary drainage is connected to the opening 122 of the standpipe 120 connected to the upstream side of the main pipe 110 to which the temporary drainage equipment 3b is connected. It is preferable to have a configuration in which the storage devices 10 and 210 that form a pair with the equipment 3b are connected. That is, the same number of storage devices 10 and 210 as the temporary drainage facilities 3b were provided, and the storage devices 10 and 210 were connected to the openings 122 of standpipes 120 located at positions adjacent to the upstream side of each of the temporary drainage facilities 3b.
