It is a part. In the present embodiment, the first vertically inclined surface 45 extends upward from the left end of the first end portion 51a (see FIG. 9) of the insertion portion 41. The first vertically inclined surface 45 is inclined in a direction away from the insertion portion 41 (here, to the left) as it goes upward from the insertion portion 41. The second vertically inclined surface 46 extends upward from the right end of the first end portion 51a of the insertion portion 41. The second vertically inclined surface 46 is inclined in a direction away from the insertion portion 41 (here, to the right) as it goes upward from the insertion portion 41. Here, the first vertically inclined surface 45 and the second vertically inclined surface 46 face each other in the left-right direction, and the length between the first vertically inclined surface 45 and the second vertically inclined surface 46 in the left-right direction is It becomes longer toward the top. In the present embodiment, a contact portion 43 is provided at the upper end of the first vertically inclined surface 45 and the upper end of the second vertically inclined surface 46.

The drainage 10 according to the present embodiment has been described above. Next, the procedure for using the drainage basin 10 will be described. For example, when it is desired to communicate the inflow tubular portion 12 and the first outflow tubular portion 13 as shown in FIG. 1, the operator first closes the rod-shaped operating member 8 as shown in FIG. It is inserted into the operation unit 44 of. Then, the operator operates the operation member 8, inserts the insertion portion 41 of the closing member 20 into the second outflow tubular portion 14, and inserts the closing member 20 into the second invert 16 as shown in FIG. Fit. At this time, the contact portion 43 of the closing member 20 comes into contact with the inner peripheral surface 32 of the main body 11. The closing plate portion 42, together with the first invert 15, functions as an invert through which drainage flows. The upper surface of the lower end portion 61 of the closing plate portion 42 and the upper surface of a part of the first invert 15 are substantially flush with each other. Further, at this time, as shown in FIG. 5, the inclined surface 63 of the closing member 20 is substantially flush with the first main body inclined surface 33 and the second main body inclined surface 34 of the main body 11.

In the present embodiment, as shown in FIG. 1, in a state where the closing member 20 is fitted to the second invert 16, the drainage that has flowed in from the inflow pipe 5 is passed through the inflow tubular portion 12 to the first body 11 It flows into 1 invert 15. Then, the drainage that has flowed into the first invert 15 flows toward the first outflow tubular portion 13 along the invert formed by the closing plate portion 42 and the first invert 15. Then, the drainage that has flowed into the first outflow tubular portion 13 flows out into the first outflow pipe 6. At this time, since the second outflow tubular portion 14 is closed by the closing member 20, the drainage in the first invert 15 does not flow into the second outflow tubular portion 14.

On the other hand, as shown in FIG. 2, for example, when the inflow tubular portion 12 and the second outflow tubular portion 14 are desired to be communicated with each other, the operator inserts the operation member 8 (see FIG. 9) inserted into the operation unit 44. By operating, as shown in FIG. 6, the insertion portion 41 of the closing member 20 is inserted into the first outflow tubular portion 13, and the closing member 20 is inserted into the portion of the first invert 15 on the first outflow tubular portion 13 side. To fit into. At this time, the contact portion 43 of the closing member 20 comes into contact with the inner peripheral surface 32 of the main body 11. The closing plate portion 42, together with the second invert 16, functions as an invert through which drainage flows. The upper surface of the lower end portion 61 of the closing plate portion 42 and the upper surface of a part of the second invert 16 are substantially flush with each other. Further, at this time, as shown in FIG. 7, the inclined surface 63 of the closing member 20 is substantially flush with the second main body inclined surface 34 and the third main body inclined surface 35 of the main body 11. In addition, in FIG. 7, it seems that a slight step is formed between the inclined surface 63 and the inclined surface 34 of the second main body and the inclined surface 35 of the third main body. "Flat" shall include some steps.

In the present embodiment, as shown in FIG. 2, the drainage that has flowed in from the inflow pipe 5 flows in in a state where the closing member 20 is fitted to the portion of the first invert 15 on the side of the first outflow tubular portion 13. Through the tubular portion 12, it gradually flows into the first invert 15 of the main body 11. Then, the drainage that has flowed into the first invert 15 flows to the invert formed by the closing plate portion 42 and the second invert 16, and then flows out to the second outflow tubular portion 14. Then, the drainage that has flowed out to the second outflow tubular portion 14 flows out to the second outflow pipe line 7. At this time, since the first outflow tubular portion 13 is closed by the closing member 20, the drainage in the first invert 15 does not flow into the first outflow tubular portion 13.

As described above, in the present embodiment, when it is desired to communicate the inflow tubular portion 12 and the first outflow tubular portion 13 as shown in FIG. 1, the insertion portion 41 is formed into the second outflow tubular portion as shown in FIG. The closing member 20 is fitted into the second invert 16 while being inserted into the portion 14. As a result, since the contact area between the insertion portion 41 and the inner peripheral surface of the second outflow tubular portion 14 is large, drainage is less likely to leak from between the insertion portion 41 and the inner peripheral surface of the second outflow tubular portion 14. can do. On the other hand, when it is desired to communicate the inflow tubular portion 12 and the second outflow tubular portion 14 as shown in FIG. 2, the insertion portion 41 is inserted into the first outflow tubular portion 13 as shown in FIG. In this state, the closing member 20 is fitted into the portion of the first invert 15 on the side of the first outflow tubular portion 13. As a result, since the contact area between the insertion portion 41 and the inner peripheral surface of the first outflow tubular portion 13 is large, drainage is less likely to leak from between the insertion portion 41 and the inner peripheral surface of the first outflow tubular portion 13. can do.

In the present embodiment, as shown in FIG. 9, the closing plate portion 42 is curved so as to be separated from the insertion portion 41 and recessed downward as it goes downward. As shown in FIG. 6, when the closing member 20 is fitted to the first invert 15 with the insertion portion 41 inserted in the first outflow tubular portion 13, the closing plate portion 42 together with the second invert 16 It plays a part of the invert where drainage flows. Here, since the closing plate portion 42 is curved, the invert formed by the closing plate portion 42 and the second invert 16 has a substantially half-pipe shape. Therefore, the drainage flows smoothly in the invert formed by the closing plate portion 42 and the second invert 16. On the other hand, as shown in FIG. 3, when the closing member 20 is fitted to the second invert 16 with the insertion portion 41 inserted in the second outflow tubular portion 14, the closing plate portion 42 becomes the first invert 15. At the same time, it plays a part of the invert where drainage flows. Therefore, since the invert formed by the closing plate portion 42 and the first invert 15 has a substantially half-pipe shape, drainage smoothly flows in the invert formed by the closing plate portion 42 and the first invert 15.

In the present embodiment, as shown in FIG. 9, the lower end portion 61 of the closing plate portion 42 has a tapered cross section. As a result, as shown in FIG. 6, when the closing member 20 is fitted to the first invert 15 with the insertion portion 41 inserted in the first outflow tubular portion 13, the lower end portion of the closing plate portion 42 The upper surface of the 61 and the upper surface of the second invert 16 are substantially flush with each other. Therefore, since the invert formed by the closing plate portion 42 and the second invert 16 has a smooth curved surface, drainage flows smoothly. On the other hand, as shown in FIG. 3, when the closing member 20 is fitted to the second invert 16 with the insertion portion 41 inserted in the second outflow tubular portion 14, the lower end portion 61 of the closing plate portion 42 The upper surface and the upper surface of the first invert 15 are substantially flush with each other. Therefore, since the invert formed by the closing plate portion 42 and the first invert 15 has a smooth curved surface, drainage flows smoothly.

In the present embodiment, as shown in FIG. 8, in a plan view, the closing plate portion 42 is formed in a tapered shape toward the center of the closing plate portion 42. Further, in the present embodiment, at least a part of the closing plate portion 42 (here, the central portion in the left-right direction of the closing plate portion 42) is curved in a plan view. As a result, the closing plate portion 42 has a tapered shape and is fitted to either the first invert 15 or the second invert 16 from the curved portion, so that the closing plate portion 42 and the first invert are formed. By gradually increasing the contact area with either the 15 or the second invert 16, the closing member 20 can be easily fitted to either the first invert 15 or the second invert 16.

In the present embodiment, as shown in FIGS. 3 and 6, in the contact portion 43 of the closing member, the insertion portion 41 is inserted into either the first outflow tubular portion 13 or the second outflow tubular portion 14. At that time, it comes into contact with the inner peripheral surface 32 of the main body 11. Therefore, when the contact portion 43 comes into contact with the inner peripheral surface 32 of the main body 11, the insertion portion 41 is appropriately inserted into either the first outflow tubular portion 13 or the second outflow tubular portion 14. It was when it was done. Therefore, by confirming that the contact portion 43 is in contact with the inner peripheral surface 32 of the main body 11, the insertion portion 41 is placed on either the first outflow tubular portion 13 or the second outflow tubular portion 14. You can confirm that it was inserted properly.

Further, in the present embodiment, as shown in FIG. 9, the contact portion 43 extends from the upper portion of the first end portion 51a of the insertion portion 41 toward the second end portion 51b. Therefore, it is easier for the operator to confirm from above the main body 11 whether or not the contact portion 43 is in contact with the inner peripheral surface 32 of the main body 11.

Further, in the present embodiment, as shown in FIG. 1, a part of the contact portion 43 is curved along the inner peripheral surface 32 of the main body 11 in a plan view. As a result, the contact area between the contact portion 43 and the inner peripheral surface 32 of the main body 11 can be increased. Therefore, by arranging the closing member 20 so that the curved portion of the contact portion 43 is in contact with the inner peripheral surface 32 of the main body 11 more and more, the first outflow tubular portion 13 and the second outflow tubular portion 13 are formed. The insertion portion 41 can be appropriately inserted into any one of the portions 14.

In the present embodiment, as shown in FIG. 9, the contact portion 43 has an inclined surface 63 that is inclined upward from the first end portion 51a to the second end portion 51b of the insertion portion 41. As a result, when the drainage flowing inside the main body 11 rides on the inclined surface 63 of the contact portion 43, the drainage is directed to either the first invert 15 or the second invert 16 along the inclined surface 63. It flows. Therefore, it is possible to prevent drainage from collecting in the contact portion 43.

In the present embodiment, for example, since the drainage basin 10 is buried in the ground, when it is difficult for the operator to directly operate the closing member 20 in the main body 11, as shown in FIG. 9, the closing member 20 is difficult to operate. It is preferable to attach the rod-shaped operating member 8 to the operating portion 44 of the 20. In this case, the insertion portion 41 of the closing member 20 can be inserted into either the first outflow tubular portion 13 or the second outflow tubular portion 14 by using the operation member 8 attached to the operation portion 44. ..

In the present embodiment, a seal member 53 is provided on the outer peripheral surface of the insertion portion 41. Therefore, as shown in FIG. 6, when the insertion portion 41 is inserted into the first outflow tubular portion 13, the insertion portion 41 and the inner peripheral surface of the first outflow tubular portion 13 are brought into close contact with each other by the seal member 53. be able to. Therefore, it is possible to further suppress the leakage of drainage from between the insertion portion 41 and the inner peripheral surface of the first outflow tubular portion 13. Similarly, as shown in FIG. 3, when the insertion portion 41 is inserted into the second outflow tubular portion 14, the insertion portion 41 and the inner peripheral surface of the second outflow tubular portion 14 are brought into close contact with each other by the seal member 53. Can be made to. Therefore, it is possible to further suppress the leakage of drainage from between the insertion portion 41 and the inner peripheral surface of the second outflow tubular portion 14.

In the present embodiment, as shown in FIG. 2, the axial length L2 of the first outflow tubular portion 13 is longer than the axial length L1 of the inflow tubular portion 12. The axial length L3 of the second outflow tubular portion 14 is longer than the axial length L1 of the inflow tubular portion 12. This makes it possible to secure a portion of the first outflow tubular portion 13 into which the insertion portion 41 is inserted. In the second outflow tubular portion 14, a portion into which the insertion portion 41 is inserted can be secured.

In the present embodiment, as shown in FIG. 6, the first outflow tubular portion 13 includes a first upstream tubular member 13a and a first downstream tubular member 13b fitted into the first upstream tubular member 13a. It is composed of and. For example, an existing main body 11, an inflow tubular portion 12, a first upstream tubular member 13a of the first outflow tubular portion 13, and a second outflow tubular portion 14 are integrally formed. In drainage, the axial length of the first upstream tubular member 13a is substantially the same as the axial length L1 of the inflow tubular portion 12. Therefore, it is difficult to insert the first outflow pipe 6 and the insertion portion 41 of the closing member 20 into the first upstream tubular member 13a at the same time. However, in the present embodiment, in the existing drainage basin, the first downstream tubular member 13b is connected to the first upstream tubular member 13a to reduce the axial length L2 of the first outflow tubular portion 13. By making the length of the inflow tubular portion 12 longer than the axial length L1, the first outflow pipe line 6 and the insertion portion 41 of the closing member 20 can be inserted into the first outflow tubular portion 13 at the same time. .. Therefore, it is possible to realize the drainage basin 10 according to the present embodiment by diverting the existing drainage basin.

In the above embodiment, the first outflow tubular portion 13 is composed of a first upstream tubular member 13a and a first downstream tubular member 13b fitted into the first upstream tubular member 13a. However, the first outflow tubular portion 13 may be formed by one member. That is, the first upstream-side tubular member 13a and the first downstream-side tubular member 13b may be integrally formed.

In the above embodiment, the second outflow tubular portion 14 is formed by one member. However, the second outflow tubular portion 14 may be composed of a plurality of members. For example, the second outflow tubular portion 14 may be composed of a second upstream tubular member and a second downstream tubular member connected to the second upstream tubular member. In this case, one end of the second upstream tubular member is connected to the side of the main body 11, and the other end of the second upstream tubular member is fitted with one end of the second downstream tubular member. There is. The other end of the second downstream side tubular member is connected to the second outflow pipe line 7 (see FIG. 1). In the present embodiment, an inserted portion into which the insertion portion 41 of the closing member 20 is inserted and a second outflow are provided on the inner peripheral surface of either the second upstream tubular member or the second downstream tubular member. A connected portion to which the pipeline 7 is connected may be formed.

The closing member 20 may be a member capable of closing the inflow tubular portion 12. In other words, the second end portion 51b of the insertion portion 41 of the closing member 20 may be inserted into the inflow tubular portion 12.

In the above embodiment, the drainage drainage 10 is buried in the ground, but is not particularly limited. For example, some or all of the drainage 10 may be located on the ground.
