The seal member 64 provides a seal between the second outlet 54 and the fitting convex portion 63 of the lid body 42.

  As shown in FIG. 2, the septic tank 70 is a tank for storing sewage. In the present embodiment, the septic tank 70 corresponds to “reserving means”. The septic tank 70 includes a purification means for purifying the sewage that has flowed out of the drainage facility 5. The septic tank 70 is a tank in which, for example, microorganisms as a purification means are placed inside, and foreign substances contained in the sewage are removed by the microorganisms and the sewage is purified by decomposing the sewage. The septic tank 70 is buried in the ground. The septic tank 70 is constituted by a tank and has a sealed space inside. A connection port 72 is formed in the upper part of the side surface of the upstream portion of the septic tank 70. As described above, the outlet 72 is connected to the connection port 72, and the second outlet 54 of the wastewater 40 is connected via the outlet 13.

  The upstream end of the overflow pipe 77 is connected to the upper part of the side surface of the downstream portion of the septic tank 70. Sewage purified in the septic tank 70 (hereinafter, the purified sewage is also referred to as “treated water”) is discharged from the downstream end of the overflow pipe 77 to the outside. Although the downstream end of the overflow pipe line 77 is not particularly limited, for example, it is connected to a side groove (not shown). Here, when sewage flows into the septic tank 70, when the level of the treated water in which the sewage is purified rises in the septic tank 70 and reaches the connection site with the overflow pipe 77, the treated water passes through the overflow pipe 77. It is discharged to the outside through.

  A cylinder 78 projects from the upper surface of the septic tank 70 in the vertical direction. The cylinder 78 is provided on the upper surface of the septic tank 70 so that the upper end is substantially the same height as the ground. An operator can perform maintenance and inspection in the septic tank 70 through the cylinder 78. When maintenance and inspection are not performed in the septic tank 70, the upper portion of the cylinder 78 is closed by a lid 79.

  Next, the utilization method of 1 A of sewage discharge systems which concern on this embodiment is demonstrated. As shown in FIG. 1, in the present embodiment, the lid body 42 (see FIG. 4) that closes the second outlet 54 of the sewage water 40 is removed, and the second outlet 54 is open. The sewage discharged from the drainage facility 5 flows into the first outflow pipe 11 and flows into the main body 41 from the inlet 52 of the sewage basin 40. At this time, the second outlet 54 is open. Further, the first outlet 53 is closed by a sealing cap 58. Therefore, the sewage that has flown into the main body 41 does not flow out of the first outlet 53 but flows out of the main body 41 through the second outlet 54. The sewage flowing out from the second outlet 54 is discharged to the septic tank 70 through the outflow pipe 13. The sewage discharged to the septic tank 70 is purified by microorganisms or the like. Then, the treated water whose sewage has been purified in the septic tank 70 is discharged to the outside through the overflow pipe 77 when the water level reaches the connection point of the overflow pipe 77 of the septic tank 70.

  By the way, in the area where the sewage system is not provided, when the sewage system is provided, the drainage system 5 and the sewage system 25 are arranged so that the sewage discharged from the drainage system 5 is discharged to the sewage system 25. It may be necessary to repair the sewage discharge system 1A so as to connect the two. Then, next, the procedure which connects 1A of sewage discharge systems and the sewage main pipe 25 is demonstrated.

  FIGS. 9 and 10 are diagrams showing a procedure for connecting the sewage discharge system 1 </ b> A and the sewage main pipe 25. Here, the case where the sewage main pipe 25 is installed on the right side of the sewage discharge system 1A in FIG. 9 will be described. In the present embodiment, the upstream end of the second outflow conduit 12 is connected to the first outlet 53 of the sewage mass 40, and the sewage main pipe 25 is connected to the downstream end of the second outflow conduit 12. Thus, the sewage discharge system 1A and the sewage main pipe 25 are connected. In addition, as shown in FIG. 10, a public mast 26 is provided in the middle of the second outflow pipe 12.

  First, the process of removing the earth and sand of the location which arrange | positions the 2nd outflow pipeline 12 between the 1st outflow ports 53 and the sewer main pipe 25 of the sewage water 40 is performed. As shown in FIG. 9, the space S is formed by removing the earth and sand where the second outflow pipe 12 is disposed. The space S is preferably a space having a width that is slightly wider than the second outflow conduit 12 in a plan view in consideration of the time required for the work and the cost required for the work.

  Next, as shown in FIG. 10, a step of arranging the second outflow conduit 12 in the space S is performed. Then, a step of connecting the second outlet pipe 12 to the first outlet 53 and the sewage main pipe 25 is performed. Here, the sealing cap 58 (see FIG. 9) that closes the first outlet 53 is removed, and the upstream end of the second outlet pipe 12 is fitted into the first outlet 53. At this time, you may fix with the adhesive agent etc. so that the upstream end of the 2nd outflow pipeline 12 may not remove | deviate from the 1st outflow port 53. FIG. Next, the downstream end of the second outflow pipe 12 and the sewage main pipe 25 are connected. Here, a hole (not shown) communicating with the second outflow pipe 12 is formed in the sewage main pipe 25. The downstream end of the second outflow pipe 12 and the sewage main pipe 25 are connected so that the hole and the second outflow pipe 12 communicate with each other. The connection method of this 2nd outflow pipe 12 and the sewer main pipe 25 is not specifically limited, For example, you may connect using a joining material.

  In the present embodiment, the step of connecting the first outlet 53 and the sewage main pipe 25 without performing the step of cutting the outflow conduit 10, that is, the first outflow conduit 11 or the outflow conduit 13. It can be carried out. For example, when the step of cutting the outflow pipe 10 is performed, as shown in FIG. 1, the space A is formed by removing the earth and sand at the location where the outflow pipe 10 is cut. However, when the step of cutting the outflow conduit 10 is not performed as in the present embodiment, a space S smaller than the space A may be formed. In this embodiment, since the process of cutting the outflow pipe 10 is not performed, it is not necessary to secure a work space for cutting. Therefore, the work cost can be reduced and the work time can be shortened.

  Next, a step of filling the space S by covering the second outflow pipe 12 with earth and sand is performed. In this way, the operation of arranging the second outflow conduit 12 is completed.

  Next, an operator performs the process of arrange | positioning the cover body 42 so that the inflow port 52 and the 1st outflow port 53 may be connected so that sewage may not flow from the inflow port 52 to the 2nd outflow port 54. FIG. Specifically, the operator closes the second outlet 54 by attaching the lid 42 to the second outlet 54. The lid body 42 can be attached to the second outlet 54 as follows, for example. First, as shown in FIG. 2, the operator removes the lid 57 placed on the inspection cylinder 56. Next, the operator inserts the hand into the inspection tube 56 with the handle 62 of the lid 42 held in the hand. Then, the lid 42 is attached to the second outlet 54 by fitting the fitting convex portion 63 of the lid 42 to the second outlet 54. If the lid 42 cannot be attached to the second outlet 54 with the handle 62 held by hand, for example, a rod-like body having a hook at the tip is used. The lid 42 may be attached to the second outlet 54 by being hooked on the second outlet 54.

  When the sewage discharge system 1A and the sewage main pipe 25 are connected, the sewage discharged from the drainage facility 5 and flowing into the main body 41 from the inlet 52 is not discharged from the second outlet 54 to the septic tank 70, It passes above the lid 42 closing the two outlets 54 and flows out of the main body 41 from the first outlet 53. The sewage flowing out from the first outlet 53 is discharged to the sewage main pipe 25 through the second outlet pipe 12.

  As described above, in this embodiment, when the sewerage facility is not maintained, the sewage discharged from the drainage facility 5 is removed by removing the lid 42 of the sewage basin 40 from the second outlet 54. It is discharged to the septic tank 70 through the outlet 54. On the other hand, when sewage facilities such as the sewage main pipe 25 are prepared, the upstream end of the second outflow pipe 12 is connected to the first outlet 53 of the sewage 40 and the downstream end of the second outflow pipe 12 is connected. Connect to sewer main 25. Furthermore, the flow path of sewage is switched by attaching the lid 42 to the second outlet 54. As a result, as shown in FIG. 10, the sewage discharged from the drainage facility 5 is discharged from the first outlet 53 of the sewage basin 40 to the sewage main pipe 25. Therefore, the operation | work which connects the drainage equipment 5 and the sewer main pipe | tube 25 can be performed, without performing the process of cut | disconnecting a pipe line like the past. Therefore, the work cost can be reduced and the work time can be shortened.

  The sewage discharged from the drainage facility 5 may contain foreign matter such as toilet paper, and the foreign matter may accumulate in the main body 41. Therefore, there is a possibility that the flow path switching function of the sewage 40 will be impaired by foreign substances. However, in the present embodiment, as shown in FIG. 4, the sewage basin 40 is provided with an inspection port 51, so that maintenance inside the main body 41 is easier. Therefore, when a foreign object is clogged in the main body 41, the foreign object can be easily removed from the inspection port 51. Therefore, the flow path switching function can be sufficiently secured, and it is easy to avoid a situation in which the lid body 42 cannot be attached to and detached from the second outlet 54.

  Moreover, in this embodiment, the 2nd outflow port 54 is provided in the position lower than the inflow port 52 and the 1st outflow port 53, and is opened below. The lid body 42 is detachably provided at the second outlet 54. Thus, when the lid 42 is attached to the second outlet 54, the inlet 52 and the first outlet 53 communicate with each other, and the communication between the inlet 52 and the second outlet 54 is blocked. Therefore, the sewage flowing into the main body 41 from the inlet 52 does not flow out from the second outlet 54. On the other hand, when the lid 42 is removed from the second outlet 54, the inlet 52, the first outlet 53, and the second outlet 54 communicate with each other. However, the second outlet 54 is provided at a position lower than the inlet 52 and the first outlet 53. Therefore, the sewage flowing into the main body 41 from the inflow port 52 does not flow out from the first outflow port 53 but flows out from the second outflow port 54. Therefore, the flow path of the sewage can be easily switched by attaching the lid 42 to the second outlet 54 or removing it from the second outlet 54.
