In the above-mentioned embodiment, the universal joint 48 is joined to the outflow pipe 20 of the rehabilitation pit 10 so as to correspond to the existing downstream pipe 34 that is inclined and installed. In the case where the pipe 34 is arranged horizontally, for example, a straight tubular joint 70 as shown in FIG. 7 may be joined instead of the universal joint 48. A rubber ring 72 is fixed to the outer peripheral surface of one end of the joint 70, and a receiving port 74 joined to the outflow pipe 20 is formed at the other end.

Further, the rehabilitation basin 10 can be applied to the case where the site is opened and cut as shown in FIG. 8, for example. In this case, the ends of the existing upstream pipe 32 and the existing downstream pipe 34 can be projected inside the open / closed portion 78, so that the universal joint 48 and the short pipe 44 can be replaced with rubber ring openings. Adhesive socket (or rubber ring socket) 80 and 82
May be formed. If the receiving port 80 and the existing downstream pipe 34 are joined and the receiving port 82 and the existing upstream pipe 32 are joined, since the diameter of the pipe line is not reduced, it is possible to prevent a decrease in water permeability. When the site is excavated, a pebbles 84 is laid on the bottom of the excavated portion 78, and a sand layer 86 is formed on the pebbles 84.
After stabilizing the rehabilitation basin 10 with the sand layer 86, earth and sand (not shown) is backfilled in the excavated portion 78.

Further, in each of the above-mentioned embodiments, the short pipe 44 is exchanged at the opening 40 to be connected to the existing upstream pipe 32. However, as shown in FIG. 9, for example, the short pipe 44 is connected to the existing upstream pipe 32. It may be exchanged in the pipe 32 and joined to the opening 40 of the rehabilitation basin 10. When the short pipes 44 are exchanged by using the existing upstream pipes 32 in this manner, it is not necessary to store the short pipes 44 in the rehabilitation basin 10 in advance, so that the case where there are two or more inflow pipes 32 is also applied. it can. However, in this case, it is necessary to form a plurality of openings 40 corresponding to the existing upstream pipes 32 on the peripheral side surface of the container body 14.
