Drainage basin and drainage structure

The present invention relates to a catch basin and a drainage structure can be switched the flow path of the effluent.

Normally, the drainage from the drainage facility installed inside the building is discharged to the sewer main through the drainage basin buried outside the building.

Here, when a liquefaction phenomenon of the ground occurs due to a disaster such as an earthquake, the manhole may float and the sewage main connected to the manhole may be damaged.

Further, even if the sewage main is not damaged, the treatment function of the sewage treatment plant may be deteriorated due to a failure of related equipment or the like.

In this way, if the wastewater cannot be sufficiently discharged from the drainage facility for some reason including a disaster and the discharge to the sewage main is regulated, there arises a problem of how to treat this wastewater.

Therefore, for example, as shown in Patent Document 1, a system has been proposed in which a plurality of outlets are provided in a drainage basin and the outlets through which the drainage is discharged can be changed by switching the flow direction of the drainage in the drainage basin. ..

That is, in the system of Patent Document 1, the rotating body inside the drainage basin is rotated to connect the downstream side of the drainage flow path provided in the rotating body to the first outlet or the second outlet. The outflow direction of wastewater can be changed.

It is a top view which shows the state which changed the flow direction of drainage in the drainage basin of the same as above.

Hereinafter, the configuration of the first embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4.

In FIG. 1, reference numeral 1 denotes a drainage basin, and the drainage basin 1 is provided in a piping path for discharging drainage from a drainage facility such as a building to a sewage main.

The drainage basin 1 includes a substantially cylindrical basin main body 3 fixed to the installation surface 2 and a rotating body 4 rotatably provided inside the basin main body 3.

The basin body 3 has a cleaning port 5 used for maintenance and the like to rotate the rotating body 4, an inflow port 6 for drainage from the drainage facility, and a plurality of flows for drainage to the outside. It has outlets 7 and 8.

The cleaning port 5 is composed of a portion of the basin body 3 that is opened upward so that maintenance and other operations can be performed from above the drainage basin 1.

The inflow port 6 is opened outward at the side portion of the box body 3, and is connected to a drainage facility such as a building via a piping member (not shown).

The outflow port 7 is opened at the side of the basin body 3 in a direction perpendicular to the inflow port 6 in a plan view, and is connected to, for example, a sewage main (not shown) and used in normal times. ..

The outflow port 8 is provided at the lower part of the main body 3 and is opened downward. For example, the outlet 8 is connected to a drainage storage facility (not shown), and the discharge of drainage to the sewage main is regulated due to a disaster or the like. It is sometimes used.

Further, the outflow port 8 is composed of an outflow member 9 arranged below the inflow port 6 in the box main body 3.

The outflow member 9 includes a tapered portion 11 that is fixed in the box body 3 below the inflow port 6 and gradually decreases in diameter downward, and a cylindrical portion that is integrally connected to the lower side of the tapered portion 11 and extends downward. Has 12 and.

Further, the lower end of the cylindrical portion 12 projects downward from the through hole 13 provided in the installation surface 2, and a drainage storage facility (not shown) is connected via a piping member (not shown). That is, the drainage basin 1 and the drainage storage facility connected to the outflow port 8 (outflow member 9) of the drainage basin 1 constitute a drainage structure for discharging drainage from the drainage facility such as a building.

In such a drainage structure, the drainage is normally discharged from the drainage basin 1 through the outflow port 7 to the sewage main, and in an emergency, the drainage is discharged from the drainage basin 1 through the outflow port 8 to the drainage storage facility. It is discharged.

The wastewater storage facility is expected to be used for the purpose of temporarily storing wastewater in a situation where the discharge of wastewater to the sewage main is restricted due to a disaster, etc., but the restoration will take a long time. Considering the case, it is preferable to have a wastewater treatment device so that not only the wastewater can be stored but also the stored wastewater can be treated.

Examples of such a wastewater treatment device include a stool tank for treating anaerobic microorganisms and a septic tank for treating aerobic microorganisms.

When the wastewater treatment equipment performs aerobic microbial treatment, electric power, which is the power for aeration, is required. Therefore, considering the situation where wastewater is discharged to the wastewater storage facility, sunlight is prepared for a power outage. It is more preferable to prepare a standby power source for power generation or the like.

The rotating body 4 has a rotating portion 14 rotatably attached to the basin main body 3 in the basin main body 3, and a drainage flow that is rotatable together with the rotating portion 14 and has the same number of drainage flows as the outlets 7 and 8. It has paths 15 and 16 and an operation unit 17 for rotating the rotating unit 14.

The rotating portion 14 is a substantially circular plate member whose outer diameter is slightly smaller than the inner diameter of the box body 3. That is, the rotating portion 14 is arranged so as to partition the cleaning port 5 side and the outflow port 8 side in the box body 3, and the outer peripheral edge portion thereof is slidably contacted with the inner peripheral surface of the box body 3. There is.

Further, a part of the outer peripheral portion of the rotating portion 14 is provided with an opening 18 that is opened in an arc shape from the outer peripheral edge portion and communicates with the outlet 8.

The drainage flow path 15 is composed of a pipe member 21 which is fixed to the rotating portion 14 and extends in an arc shape in a plan view.

The pipe member 21 is fixed to the rotating portion 14 by a fixing portion 22 provided at the lower portion, and can rotate with respect to the box body 3 together with the rotating portion 14.

Here, in a state where one end of the pipe member 21 is arranged corresponding to the inflow port 6, the other end is arranged corresponding to the outflow port 7.

That is, when the drainage flow path 15 is connected so that one end of the pipe member 21 faces the inflow port 6, the other end of the pipe member 21 is connected so as to face the outflow port 7, and the drainage channel 15 is connected. It is in a state of communicating from the inflow port 6 to the outflow port 7 via the flow path 15.

Then, the drainage that has flowed into the drainage basin 1 from the inflow port 6 is guided to the outflow port 7 by the drainage flow path 15 (pipe member 21).

The drainage flow path 16 is composed of a plate member 23 having an arcuate shape in a plan view, which is integrally provided so as to surround the peripheral edge of the opening 18 of the rotating portion 14.

In the plan view shown in FIG. 3, both ends of the arc of the plate member 23 are slidably in contact with the inner peripheral portion of the box body 3.

Further, the plate member 23 is erected substantially vertically from the peripheral edge of the opening 18 in the rotating portion 14 in the cross-sectional view shown in FIG. 4, and the upper end portion thereof is located above the bottom portion of the inflow port 6. .. Therefore, in a state where the plate member 23 is arranged so as to face the inflow port 6, a part in front of the inflow port 6 (a part on the lower side in the flow direction of drainage) is covered by the plate member 23.

The plate member 23 is rotatable with respect to the box body 3 together with the rotating portion 14, and the tip end portion (upper end portion) of the plate member 23 constitutes one end portion of the drainage flow path 16 to rotate the plate member 23. The base end portion (lower end portion) connected to the opening 18 of the moving portion 14 constitutes the other end portion of the drainage flow path 16.

Further, in the drainage flow path 16 composed of the plate member 23, since the lower end portion of the plate member 23 always communicates with the outlet 8, the rotating portion 14 is rotated to allow the upper portion of the plate member 23 to flow. By arranging so as to face the inlet 6, that is, by making one end of the drainage flow path 16 face the inflow port 6, the inflow port 6 to the outflow port 8 pass through the drainage flow path 16. It will be in a state of communication.

In this way, the drainage flow path 15 and the drainage flow path 16 can rotate together with the rotating body 4 and can guide the flow of drainage separately independently of each other. Therefore, by rotating the rotating body 4, the state of communicating from the inflow port 6 to the outflow port 7 via the drainage flow path 15 and the state of communicating from the inflow port 6 to the outflow port 8 via the drainage flow path 16. It is possible to switch to and. That is, by rotating the rotating body 4, the drainage channel (drainage channel 15 or drainage channel 16) and the outlet (outlet 7 or outlet 8) through which the drainage flows can be selected.

Next, the operation and effect of the first embodiment will be described.

<Normal time>
First, in the normal state where the drainage from the drainage facility is discharged to the sewage main through the drainage basin 1, one end of the drainage flow path 15 faces the inflow port 6 and drains as shown in FIGS. 1 and 2. The inflow port 6 to the outflow port 7 are communicated with each other through the flow path 15.

In the state of communicating from the inflow port 6 to the outflow port 7 via the drainage flow path 15, the drainage flowing into the drainage basin 1 from the inflow port 6 is guided toward the outflow port 7 along the drainage flow path 15. It flows like this and is discharged to the sewage main through the outlet 7.

<Emergency>
Next, in an emergency such as when the discharge of drainage to the sewage main is restricted due to a disaster or the like, the operation unit 17 is rotated from the cleaning port 5 to rotate the operation unit 3 with respect to the basin body 3. The moving body 4 is rotated.

That is, as shown in FIGS. 3 and 4, the inflow port 6 and the outflow port 7 do not communicate with each other through the drainage flow path 15, and one end of the drainage flow path 16 faces the inflow port 6. The state is such that the inflow port 6 and the outflow port 8 communicate with each other via the drainage channel 16.

In the state of communicating from the inflow port 6 to the outflow port 8 through the drainage flow path 16, the drainage flowing into the drainage basin 1 from the inflow port 6 falls toward the outflow port 8 through the drainage flow path 16 by its own weight. At the same time, the drainage that is vigorously scattered in the horizontal direction from the inflow port 6 also collides with the plate member 23 and flows so as to fall toward the outflow port 8.

The drainage that has passed through the drainage channel 16 in this way is supplied to the drainage storage facility through the outlet 8 and stored.

Then, according to the drainage basin 1, since the rotating body 4 has drainage channels 15 and 16 independent of each other, it is possible to switch the drainage channels 15 and 16 for flowing the drainage only by rotating the rotating body 4. In addition, it is easy to design the arrangement and configuration of the outlets 7 and 8 and the drainage channels 15 and 16 according to the situation of the installation location of the drainage basin 1. Therefore, the drainage basin 1 can easily switch the flow direction of the drainage and can improve the degree of freedom in design.

Further, since the drainage basin 1 is provided with the outflow port 8 at the lower part of the basin main body 3, the drainage can be discharged from the outflow port 8 by utilizing the falling motion of the drainage, and the configuration can be further simplified. ..

Further, by arranging the outlet 8 to be used in an emergency at the lower part of the basin body 3, the drainage storage facility can be installed below the drainage basin 1, so that it is easy to install even when the construction is carried out in a narrow place, for example.

In the first embodiment, the drainage storage facility is connected to the outlet 8, but the configuration is not limited to this, and the outlet 8 is used according to the intended purpose of use. Various facilities may be connected.

Further, the basin body 3 has a configuration in which the outlet 8 used in an emergency is provided at the lower part of the basin body 3, but the configuration is not limited to this, and the position of the outlet 8 can be appropriately selected. is there. For example, if the outlet 8 for emergency use is provided on the side of the basin body 3, the drainage storage facility can be installed on the side of the basin 1 and the amount of excavation during construction can be reduced. When there is sufficient space in the place, the construction work can be facilitated as compared with the case where the drainage storage facility is installed below the drainage basin 1.

The drainage flow path 15 has a configuration in which one end is directly connected to the inflow port 6 and the other end is directly connected to the outflow port 7, but the configuration is not limited to this, and one end is connected to the inflow port 6. It is sufficient that the drainage path is formed by communicating from the inflow port 6 to the outflow port 7 via the drainage channel 15.

The drainage flow path 16 has a configuration in which one end faces the inflow port 6 and the other end always communicates with the outflow port 8, but the configuration is not limited to this, and one end flows. If it is configured to communicate from the inflow port 6 to the outflow port 8 via the drainage flow path 16 when facing the inlet 6, it is directly connected to the inflow port 6 and the outflow port 8 as in the drainage flow path 15, for example. It may be configured.

Further, although the Masu main body 3 is provided with two outlets (outlets 7 and 8), the number of outlets can be changed as appropriate, for example, the configuration is as in the second embodiment described later. You may.

Further, the basin body 3 is provided with the same number of drainage channels (drainage channels 15, 16) as the outlets (outlets 7, 8), but the configuration is not limited to such a configuration, and a plurality of drainage channels are provided. As long as the drainage channels of the above are independent of each other and can correspond to each outlet, the number may be different from that of the outlet.

Further, the configurations of the drainage channels 15 and 16 can be changed as appropriate, and if the drainage channels are independent of each other, for example, the configuration as in the third embodiment described later may be used.

Next, the second embodiment will be described with reference to FIGS. 5 to 7. The same configurations and operations as those of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In this second embodiment, in addition to the outlets 7 and 8, an outlet 31 is provided on the side of the box body 3 as compared with the first embodiment.

Then, as shown in FIG. 5, the drainage flow is as shown in FIG. 6 by rotating the rotating body 4 from the normal state in which the inflow port 6 and the outflow port 7 communicate with each other via the drainage flow path 15. It is in a state of communicating from the inflow port 6 to the outflow port 8 via the road 16.

Further, by rotating the rotating body 4, as shown in FIG. 7, a state in which the drainage flow path 15 is communicated from the inflow port 6 to the outflow port 31 via the inverted drainage flow path 32, that is, the drainage flow path One end of 32 faces the inflow port 6, and the other end is connected to the outflow port 31.

In this way, the degree of freedom in design can be further improved by configuring the drainage outlet 31 to be discharged separately from the outlets 7 and 8.

Next, a third embodiment will be described with reference to FIGS. 8 and 9. The same configurations and operations as those of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In the third embodiment, in contrast to the first embodiment, the outlet 35 is provided on the side of the basin body 3 instead of the outlet 8, and the pipe member 36 is provided instead of the drainage channel 16. It is a configuration provided with a drainage channel 37 composed of.

Then, as shown in FIG. 8, by rotating the rotating body 4 from the state of communicating from the inflow port 6 to the outflow port 7 via the drainage flow path 15, the drainage flow path 37 is formed as shown in FIG. It is in a state of communicating from the inflow port 6 to the outflow port 35 via the inflow port 6.
