Description

[Detailed description of the invention] The present invention relates to a convenient drainage basin that is easy to position during piping construction and allows the position of the socket to which the pipe is connected to be immediately known even after construction.

In recent years, flush toilets and sewage piping work has become easier to construct using synthetic resin drainage basins.

The drainage basin used for such piping work is a straight type drainage basin 1a with a straight groove 11a formed at the bottom as shown in Fig. 4, or a straight groove 11a and a curved groove that joins the straight groove 11a from the right side. Right YT type drainage basin 1b formed with 12b or straight groove 11
There are various other types, including the left YT type drainage basin 1c, which has a curved groove 12c that joins the curved groove 12c from the left side, but all drainage basins have a straight groove as shown in Figure 4. 11a, 11b,
Pipe 2 at the end of 11c and curved grooves 12b and 12c.
Sockets 13a, 13b, 13 to be inserted and connected
c, and the upper end opening 14 of the drainage basin.
a, 14b, and 14c removable lid body (not shown)
It is covered with

By the way, the drainage basins 1a, 1b,
When performing piping work using 1c, as shown in Figures 4 and 5, the water thread L is
Straight groove 1 of each drainage basin when viewed from directly above
It is necessary to position and bury each drainage basin 1a, 1b, 1c in the soil so that 1a, 11b, 11c overlap with this water thread L and each pipe 2 has an appropriate slope. becomes.

However, in the right YT type drainage basin 1b and the left YT type drainage basin 1c other than the straight type drainage basin 1a, the center line of the straight grooves 11b and 11c is offset from the center line of the drainage basin itself, so the drainage basin is It is not possible to align the center line with the water thread L, and the straight grooves 11b,
Sockets 13b, 13b, 13c at both ends of 11c,
Since the distance to 13c was far away, it was inconvenient that I had to swing down to position it.

In addition, even after construction, such water distribution equipment may be dug up and rebuilt when it is necessary for expansion, renovation, or repair. With conventional drainage basins, it is not possible to accurately determine the position of each buried socket, and therefore the position of the pipes, so remove the lid of each drainage basin one by one and check the socket position while digging There was also the inconvenience of having to wake up.

This invention was made with the aim of eliminating the above-mentioned inconvenience, and in the conventional drainage basin,
This drainage basin is characterized in that a socket position indicator is provided on the rim of the upper opening, positioned directly above the center line of the socket.

Hereinafter, the drainage basin of the present invention will be described in detail with reference to examples.

The drainage basin 1 of the embodiment shown in Figs. 1 and 2 has a straight groove 11 and a curved groove 12 that joins the straight groove 11 from the left side.
It is a left YT type drainage basin formed at the bottom of the basin.
Sockets 13, 13', 13'' for inserting and connecting pipes are integrally formed at the ends of the straight groove 11 and the curved groove 12, projecting from the side wall. , is covered with a circular removable lid 15. This lid 15 has a pair of grips 151, 151 and a lattice uneven pattern 152 for preventing slipping on its surface.
It is attached almost flush with the mouth edge 16 of.

Furthermore, the mouth edge 1 of the upper end opening 14 of this drainage basin 1
6, a socket position display section 17, 17', 17'', which is a feature of the present invention, is attached to each socket 13, 13', 17''.
13'' center lines l, l', l''. In this embodiment, the socket position display portions 17, 17', and 17'' each consist of a protruding strip 17a having a triangular cross-sectional shape as shown in FIG. 3A.
The ridges are provided in the same direction as the center lines l, l', l'' of each socket so that they overlap exactly with the center lines l, l', l'' of each socket. There is no particular restriction on the groove, for example, a V-shaped groove 17b as shown in FIG.
It may also be a simple straight line 17c drawn with paint or the like as shown in FIG. In some cases, it is also possible to provide an arrow-shaped socket position display section that indicates the flow direction at the same time, or a socket position display section that also indicates the depth to the socket, socket diameter, etc. Furthermore, if necessary, each socket 13, 13', 13'' may also be provided with a similar indicator indicating the center.

The drainage basin 1 as described above is positioned so that the straight groove 11 overlaps the water thread L when viewed from directly above, as in the case of the conventional left YT type drainage basin 1c shown in Figs. In that case, the line connecting the socket position display parts 17, 17' located directly above the sockets 13, 13' at both ends of the straight groove 11
1, so these display parts 17,
17' can be positioned by visual measurement so that it overlaps with the water thread L, and even if it is overlapped by visual measurement, the distance between the water thread L and the socket position display parts 17, 17' is short and accurate positioning can be performed. This eliminates the trouble of having to position the bottom swinger by hanging it from the water line L to the socket as in the case of conventional drainage basins. Even when excavating and re-working after construction, if there is a socket position display section 17, 17', 17'' as in the present invention, it is possible to locate the sockets 13, 13', 13 just by looking at the display section. '' and the position of the pipe, it eliminates the trouble of having to remove the lid and look inside to check the position of the socket, which is the case with conventional drainage basins.

Furthermore, if the socket position display portions 17, 17', 17'' are provided with protrusions 17a as shown in FIG. 3A, as in this embodiment, V as shown in FIG.
There is no inconvenience such as the character-shaped groove 17b being buried in soil and becoming difficult to see, or the straight line 17c drawn with paint as shown in Figure 3C, gradually disappearing, and the display remains clear. There are some remaining benefits. Furthermore, as mentioned above, when providing an arrow-shaped socket position display section that allows you to see the direction of flow,
By looking at the display and knowing the position and number of sockets and the direction of flow, the type of drainage basin can be immediately determined.In addition, a socket position display is provided that also indicates the depth of the socket, the diameter of the socket, etc. In such cases, it is even more convenient because it allows you to know the depth of the buried pipe and the thickness of the pipe when digging.

The present invention has been explained above using the case of a left YT type drainage basin as an example, but the present invention is not limited to such a left YT type drainage basin, but can be applied to various conventional types of drainage basins. In addition, if a cylindrical adjuster or the like for depth adjustment is added to the rim 16 of the upper end opening 14 to create a deep drainage, a similar display is provided on the rim 16 of the upper end opening of the adjuster. Needless to say, it is sufficient to form .
