  By the way, such drainage basins are arranged at important points such as junctions and bends of drainage pipes, and function so that drainage catching, merging, direction change and relaying can be performed well, and drainage pipes It has a function to be used for maintenance and inspection.

  However, the above-described conventional drainage basins have only these functions. Therefore, for example, due to an earthquake or other earthquake disaster, the outflow pipe or drain main is damaged and the drainage leaks, or foreign substances such as dust are clogged and the drainage overflows without flowing into the drain main. Even if such an abnormal situation occurred, it did not have a function capable of coping with it.

  Therefore, the present invention has been made in view of such a point, and the object of the present invention is to provide a drainage function that can appropriately cope with an abnormality such as leakage of drainage in the drainage pipe. It is to provide a drainage facility equipped with this.

  The drainage basin according to the present invention includes an inspection port provided at an upper portion, an inlet port to which an inflow pipe is connected to allow drainage to flow in, and a first outlet port to which a first outlet pipe is connected to drain the drained drainage And a second outlet having a connection structure to which a second outlet pipe is connected to allow the drained water to flow out, and a detachable attachment to the second outlet to close the second outlet. And a lid provided freely.

  In such a drain, the normal drainage flows into the main body from the inflow pipe through the inflow port, and is discharged from the first outflow port to the drainage main pipe through the first outflow pipe. On the other hand, for example, when the first outflow pipe or the drain main pipe is damaged or an abnormal situation such as clogging with foreign matter such as dust occurs, the closed state of the second outlet by the lid is released. Open. Thereby, a part of waste water which flowed into the main body is discharged to the outside through the second outlet and the second outlet pipe. As a result, the amount of drainage flowing out from the first outlet to the first outlet pipe is reduced, so that the amount of drainage leakage is reduced and the amount of drainage flowing out to the inspection port side is reduced. This makes it possible to efficiently perform restoration work such as repair of an abnormal part. Here, the “connection structure” means that the second outlet is composed of, for example, a receiving port or a slot.

  Further, the second outlet may be provided at the lower part of the main body.

  If it does in this way, at the time of opening of the 2nd outflow port, it will become possible to fall naturally into the 2nd outflow side the drainage which flowed into the main part from the inflow port. As a result, the amount of drainage to the first outlet in the event of an abnormality can be reduced, so that restoration work such as repair of the abnormal part can be performed efficiently. The “mass lower part of the main body” mentioned here means a part of the main body located below the central axis of the second outlet.

  Further, the lid body may be provided with a lid body having a substantially C-shaped or U-shaped cross section that forms a flow path connecting from the inflow port to the first outflow port.

  According to this, when the lid is closed, the waste water that has flowed into the main body from the inflow port is formed in a substantially C-shaped or U-shaped cross section along the lid main body constituting the flow path (invert). It flows to the first outlet and is discharged to the drain main through the first outlet pipe. That is, the water flow is not disturbed by the lid, and the original smooth drainage flow from the inlet to the first outlet is satisfactorily maintained.

  The inflow port and the first outflow port are arranged to face each other, and a lid is provided with a handle, and the handle is in an axial direction connecting the inflow port and the first outflow port or perpendicular thereto. It may be arranged in the direction.

  According to this, it becomes possible to recognize in advance the position and direction of the handle of the lid. Therefore, for example, even when the handle is submerged and cannot be visually recognized when an abnormality occurs, the lid can be removed relatively easily.

  Furthermore, in order to make the second outflow port openable and closable, the lid body may be provided on the main body so as to be rotatable.

  In this case, when the lid is rotated to open the second outlet, a part of the drainage flows out to the second outlet pipe through the second outlet. In this way, by providing the lid body so as to be rotatable on the main body, it is not lost when the lid body is attached or detached.

  Further, when the lid is rotated to open the second outlet, the lid is arranged in front of the first outlet and regulates the outflow of drainage from the first outlet, or The first outflow port can be closed.

  According to this, for example, when an abnormal situation such as leakage of drainage occurs on the first outflow pipe side, the lid is rotated to open the second outlet. As a result, the lid body is arranged in front of the first outlet port, and the outflow of drainage to the first outlet port is restricted, or the first outlet port is closed by the lid body. For this reason, much waste water that has flowed into the main body flows out from the second outlet to the second outlet pipe, or all drainage flows out of the second outlet to the second outlet pipe. As a result, restoration work such as repair of an abnormal part occurring on the first outflow pipe side can be performed more efficiently.

  Furthermore, the drainage facility according to the present invention is connected to the above-described drainage basin, the inflow pipe connected to the inflow port, the first outflow pipe connected to the first outflow port, and the second outflow port. A second outflow pipe and a storage tank for storing drainage discharged into the second outflow pipe, or a bypass pipe connected between the second outflow pipe and a public basin It is.

  According to this, for example, when an abnormal situation such as leakage of drainage occurs on the first outflow pipe side, when the closed state of the second outlet by the cover is released, A part is discharged from the second outlet to the storage tank through the second outlet pipe, or discharged from the second outlet to the public via the second outlet pipe and the bypass pipe. As a result, since the amount of drainage flowing out from the first outlet to the first outlet pipe is reduced, the amount of drainage leakage is reduced. This makes it possible to efficiently perform restoration work such as repair of an abnormal part.

  In addition, since the drainage basin and drainage facility according to the present invention have a very simple configuration, the production can be easily and inexpensively, and a series of construction work can be performed efficiently and in a short period of time. .

  As described above, according to the present invention, when an abnormality such as leakage of drainage occurs in the drainage pipe, it is possible to appropriately treat the drainage, thereby efficiently performing the restoration work. It becomes possible.

<First Embodiment>
Hereinafter, an embodiment of a drainage basin according to the present invention will be described with reference to the drawings. 1 to 3 show a drain according to the present embodiment, FIG. 1 is a plan view, FIG. 2 is a front sectional view, and FIG. 3 is a side view.

  The main body 1 has an inspection port 2 provided in the upper center for connecting an inspection tube, an inlet 3 provided on one side for connecting an inflow pipe, and an inlet 3 for connecting a first outflow pipe. 1st outflow port 4 provided in the other side part which counters, and as shown in Drawing 2 and Drawing 3, it has a connection structure to connect the 2nd outflow pipe, and the downward 2nd outflow port provided in the lower center And 5. In addition, although the connection structure of the 2nd outflow port 5 is comprised, for example by a receptacle, a slot, etc., in this embodiment, as shown in FIG. 2, it is comprised by the receptacle. Further, as shown in the figure, the central axis P of the first outlet 4 is set to be located slightly below the central axis Q of the inlet 3. The second outlet 5 is disposed below the central axis P of the first outlet 4.

  Usually, the second outlet 5 of the main body 1 is closed by a lid 10. In this closed state, the lid body 11 is formed in a substantially C-shaped cross section as shown in FIG. 4C so as to form a flow path connecting from the inlet 3 to the first outlet 4. A substantially semi-circular handle 12 is provided at the upper center of the lid body 11. When the second outlet 5 is closed by the lid 10, the handle 12 is connected to the inlet 3 and the first inlet 11. It will be arranged in a direction orthogonal to the axial direction connecting the outlet 4. Further, a substantially cylindrical fitting convex portion 13 that can be fitted to the second outlet 5 is provided at the center of the lower surface of the lid body 11 so as to close the second outlet 5. The rubber seal ring 14 attached to the outer peripheral portion 13 seals between the two. The main body 1 and the lid body 10 are made of a synthetic resin such as vinyl chloride or polypropylene. However, the specific material is not limited to this. Further, the shape of the lid body 11 is not limited to a substantially C-shaped cross section. For example, it may be formed in the shape of a substantially U-shaped cross section, or may be formed in other shapes.

  The drainage basin according to the present embodiment is configured as described above. This drainage basin A is used by being incorporated in, for example, the following drainage equipment. Such drainage equipment B is mainly used in facilities such as schools and meeting places that are used as evacuation sites during disasters. It is not limited to this.

  As shown in FIGS. 5 and 6, the drainage facility B is buried in the ground in the site X, the drainage basin A, the inflow pipe 30 inserted and connected to the inlet 3 of the main body 1, The 1st outflow pipe 31 inserted and connected to the 1 outflow port 4, the 2nd outflow pipe 32 connected to the 2nd outflow port 5, and the storage tank to which the other end part of this 2nd outflow pipe 32 is connected 33. The second outflow pipe 32 includes an elbow 34 inserted and connected to the second outlet 5, a straight pipe 35 connected to the elbow 34, an elbow 36 connected to the straight pipe 35, and the elbow 36 And a straight pipe 37 connected between the storage tank 33 and the storage tank 33. The first outflow pipe 31 is connected to the sewage main pipe through a public basin arranged on the public road Y side. The capacity, shape, and the like of the storage tank 33 are set to an optimal size, shape, and the like in consideration of, for example, the type of installation facility and installation space. A cylindrical portion 38 projects from the upper surface of the storage tank 33 in the vertical direction. As described above, the drainage facility B can be constructed inexpensively and easily because the overall configuration is very simple.

  An inspection cylinder 39 is connected to the inspection port 2 of the drainage basin A, and the upper part thereof is closed by an inner lid 40. Further, in order to protect the inspection cylinder 39 and the inner lid 40, a protective lid 42 is arranged so as to cover the upper part thereof, and a load from the ground is supported by the protective lid 42. The protective lid 42 is supported by a substantially disk-shaped pedestal 41 embedded in the ground, whereby the load acting on the protective lid 42 is evenly distributed on the ground.

  In the drainage system B having the above-described configuration, the drainage from the facility or the like is usually drained from the inflow pipe 30 through the inlet 3 of the A, and then flows into the main body 1 and above the lid main body 11. Is further discharged from the first outlet 4 to the main drain through the first outlet pipe 31 and the public basin. In this case, since the lid body 11 is formed in a substantially C-shaped cross section so as to form a flow path connecting from the inlet 3 to the first outlet 4, the water flow is disturbed by the lid 10. The original flow of drainage from the inlet 3 to the first outlet 4 is maintained well. This is the same even when the cross-sectional shape of the lid body 11 is substantially U-shaped.

  On the other hand, if the first outflow pipe 31 or the like is damaged due to, for example, an earthquake or other earthquake disaster, the drainage will leak from the damaged portion. Further, when foreign matters such as dust are clogged in the first outflow pipe 31 and the like, the water level in the drainage water A will rise due to the drainage passage being blocked. When such an abnormal situation is found, first, the protective lid 42 and the inner lid 40 of the base 41 are removed. Next, the handle 12 of the lid body 10 is pulled up, and the lid body 10 is detached from the second outlet 5 of the main body 1 as shown in FIG. When the hand 12 does not reach the handle 12, for example, a rod-like body having a hook at the tip may be used, and the hook may be hooked on the handle 12 and pulled up.

  In this case, the handle 12 of the lid 10 is arranged in the center of the main body 1 and in a direction perpendicular to the axial direction connecting the inlet 3 and the first outlet 4. If the operator recognizes it, or if the operator can recognize it by clearly indicating it on the protective lid 42 or the inner lid 40, the drainage that has flowed into the inspection port 2 or the inspection cylinder 39 will have Even when the hand 12 is submerged and cannot be seen from above, the lid 10 can be removed relatively easily, which is very effective. The handle 12 may be provided so as to be arranged in the axial direction connecting the inflow port 3 and the first outflow port 4. In this case, the same function and effect can be obtained. However, when the handle 12 is provided on the lid body 10, it is not always necessary to arrange it in this way.

  When the second outlet 5 is opened as described above, the waste water is discharged from the second outlet 5 to the storage tank 33 through the second outlet pipe 32. In this case, since the second outlet 5 is provided downward at the lower part of the main body 1, waste water that has flowed into the main body 1 from the inlet 3 can be naturally dropped to the second outlet 5 side. Become. Thereby, since the amount of drainage to the 1st outflow port 4 side can be reduced, the amount of drainage leaks also decreases and the amount of drainage which flows out to the above-mentioned inspection port 2 side is reduced. As a result, it is possible to efficiently perform restoration work such as repair of an abnormal part on the first outflow pipe 31 side without stopping drainage from the facility or the like.

  In addition, as shown in FIG. 8, when the obstruction Z exists in the circumference | surroundings of the drainage drain A, the inflow pipe 30, etc., it is possible to cope by changing the piping form of the 2nd outflow pipe 32 suitably. That is, as shown in FIG. 9, the elbow 34 is connected to the second outlet 5 so that the tip faces the public road Y side, and the straight pipe 35, the elbow 36, and the straight pipe 37 are connected to the elbow 34 (FIG. 8). reference). In this case, since the second outlet 5 to which the elbow 34 is connected is provided downward at the lower portion of the main body 1, the first outlet pipe 31 and the second outlet pipe 32 are vertically spaced apart from each other by a predetermined distance. It can be arranged. That is, the second outflow pipe 32 can be piped without being affected by the first outflow pipe 31, and the degree of freedom of the pipe can be sufficiently secured.

  In addition, after the series of restoration work is completed, the second outlet 5 is closed again with the lid 10. As a result, drainage of the drainage from the second outlet 5 is prevented, while drainage that has flowed into the main body 1 from the inlet 3 flows out to the first outlet 31 through the first outlet 4 as before. Will be.
