Description

[Detailed explanation of the invention] This invention relates to drainage basins, more specifically, drainage basins that are buried underground and change the direction of drain pipe connections. The purpose of the present invention is to provide a drainage basin in which the direction of the drainage pipe connection can be set in various directions.

Hereinafter, embodiments of the present invention will be described based on the drawings. The drainage basin according to the present invention has one of the eight side surfaces of the bottomed cylindrical main body 1 with an octagonal cross section that is buried underground as a reference plane, and the drainage basin is constructed along the circumferential direction of the side surface. Entrance/exit ports 2 for communicating the inside and outside of the main body are provided through a total of four faces, which are faces having face angles of 45 degrees, 90 degrees, and 180 degrees with respect to the reference face, respectively, and the reference face. As shown in FIGS. 1 and 2, the main body 1 is made of synthetic resin and has a bottomed cylindrical shape with an open top and a closed bottom. A flange portion 3 is provided on the upper edge of the main body 1 over the entire circumference. The outer peripheral edge of the flange portion 3 has a substantially square planar shape, and a projecting edge 4 projects upward from the outer peripheral edge of the flange portion 3 .
Step portion 5 formed between flange portion 3 and projecting edge 4
A cover plate 21 is placed on the top. On the side of the main body 1, one of the eight side surfaces is used as a reference surface, and there are a total of four surfaces with surface angles of 45 degrees, 90 degrees, and 180 degrees with the reference surface, respectively. Entrance/exit ports 2 communicating between the inside and outside of the main body are provided respectively. The entrance/exit 2 is formed only on either the left or right side of the straight line connecting the surface facing the reference surface and the reference surface. By connecting the drain pipes 13 to any two of the four entrances and exits 2, the two drain pipes 13 can be connected at any angle that is a multiple of 45 degrees. A cap 27 is fitted to the inlet/outlet 2 to which the drain pipe 13 is not connected. The diameter a of the entrance/exit 2 is the width b of one of the sides
is set smaller than. Incidentally, the entrance/exit 2 is provided with a connector section 6 for connecting a drain pipe 13. The connector part 6 may be made into a cylindrical shape and directly connect the drain pipe 13, but depending on the purpose, a third
The shape may be as shown in FIGS. 5 to 5. In the one shown in FIG. 3, the connector part 6 is cylindrical and protrudes outward from the main body 1 from the periphery of the entrance/exit port 2.
A male threaded portion 7 is formed on the outer peripheral surface of the connector portion 6 . A female thread 9 provided on the inner peripheral surface of a socket 8 is screwed into the male thread 7 to connect the socket 8 to the main body 1. The socket 8 has a shape in which three types of cylindrical bodies 10, 11, and 12 with different diameters are connected in stages, and can be connected to any cylindrical body 10, 11, 12 and the drain pipe 13 depending on the diameter of the drain pipe 13. It is becoming possible to connect with In the case of the connector part 6 shown in FIG. 4, three grooves 14 and 1 are formed concentrically.
5 and 16 are formed on the outer surface of the main body 1, and the drain pipe 13
By punching along arbitrary grooves 14, 15, and 16 according to the diameter of the drain pipe 13, an inlet/outlet 2 matching the drain pipe 13 is formed. The connector part 6 shown in FIG. 5 is used when a drainage basin is used as a smell trap, and one end is opened downward and an elbow 17 protruding below the water surface 18 is connected to the socket 8. It's summery. That is, the socket 8 connects two types of cylinders 19 and 20 with different diameters, inserts the cylinder 19 with the smaller diameter into the entrance/exit 2, makes the end protrude into the main body 1, and inserts the elbow 1 here.
7. Of course, the drain pipe 13 is connected to the cylindrical body 20 having the larger diameter. By the way, the opening on the top surface of the main body 1 is connected to the cover plate 2.
1, but the drain pipe 13
The depth at which the main body 1 is buried also changes depending on the depth at which the main body 1 is buried.

Therefore, in order to expose the cover plate 21 to the ground surface, a spacer 22 as shown in FIG. 6 is used. The spacer 22 has a U-shaped portion 23 at its lower end, and this U-shaped portion 23 straddles the flange portion 3 and the projecting edge 4 on the upper edge of the main body 1 to lock the spacer 22 to the main body 1. At the upper end of the spacer 22, a flange portion 24 and a projecting edge 25 similar to the upper edge of the main body 1 are formed over the entire circumference, and the lid plate 21 is placed on a step portion 26 formed between the two. . Note that the height of the spacer 22 is appropriately selected depending on the buried depth of the main body 1. In addition to the body 1 having an octagonal cross section,
A circular shape as shown in FIG. 7 or another polygonal shape can be similarly used, and the flange portion 3 is not limited to a square shape. Furthermore, the positions of the entrances and exits 2 are not limited to four, but may be provided at five or more locations.

As described above, the present invention uses one of the eight side surfaces of a bottomed cylindrical body with an octagonal cross section as a reference surface, and the surface angle between the side surface and the reference surface is determined along the direction of the side surface. Since the entrances and exits communicating with the inside and outside of the main body were installed on a total of four sides (45 degrees, 90 degrees, and 180 degrees, respectively, and the reference plane), the flow direction of the drain pipe can be adjusted to any multiple of 45 degrees. It has the advantage that it can be set at an angle.
