[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of one embodiment of a drainage basin device with a trap according to the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 31 denotes a drainage basin main body made of hard vinyl chloride resin or the like. The drainage basin main body 31 has, for example, a substantially cylindrical shape having a diameter of 200 mm or less, and a cleaning port 32 having an enlarged diameter as a receiving port. An opening is formed at the top, and the bottom is closed to form a soil reservoir 33. And in this cleaning opening 32,
The cleaning port tube 34 is fitted and connected and rises up to the ground surface G, and a removable lid 35 or a reduced diameter portion of a lid receiver is fitted and closed in the opening at the upper end. .

An inflow port 36 having a diameter of, for example, 50 mm to 75 mm is protruded outward from an upper portion of one side of the drainage basin body 31. A drain pipe 37 from a foot washing place installed outside the building is fitted and connected to the formed receptacle.

Then, from a position on the other side of the drainage basin main body 31 slightly lower than the inlet 36, for example, a diameter of 50 mm
An outlet 38 of 100 mm is provided so as to be curved downward by about 90 degrees. The end of the outlet 38 is enlarged to form a receiving port 38a, and an annular groove 39 is formed near the end of the inner periphery of the receiving port 38a.

Reference numeral 41 denotes a substantially U-shaped trap tube. An annular concave portion 42a in which an elastic ring 42 such as an O-ring is fitted, and an annular concave portion 42a Are formed in parallel with the annular projection 43. Then, one end of the trap tube 41 is fitted into the receiving port 38a of the outlet 38, the elastic ring 42 is brought into close contact with the inner peripheral surface of the receiving port 38a, and the annular groove 39 engages with the annular projection 43. It is connected in a liquid-tight and rotatable manner. And this trap tube 41
A lower opening 44a of a substantially T-shaped branch joint (cheese) 44 is fitted and connected to the other end of the branch joint 44. A cleaning port pipe 46 is fitted and connected to an upper opening 44b of the branch joint 44. A drainage pipe 47 on the downstream side connected to a sewer main pipe (not shown) is fitted and connected to the side opening 44c. Also, the cleaning pipe 46
Is raised up to the ground surface G, and the upper end portion is closed with a lid 48 detachably fitted.

The respective connection parts by fitting are firmly bonded and fixed by an adhesive.

Thus, in the drainage basin device with a trap according to the present embodiment, the drainage containing the earth and sand from the foot washing place is discharged to the drainage pipe.
When flowing into the drainage basin main body 31 from the inflow port 36 through 37, such soil and sediment settles and accumulates in the reservoir 33 at the bottom of the drainage basin main body 31, and only the supernatant liquid passes through the trap pipe 41 and the like. It flows out to the drainage pipe 47 on the downstream side. So, the trap tube
The outflow of the earth and sand to the drain pipe 41 and the downstream drain pipe 47 is small, and the clogging of the trap pipe 41 and the downstream drain pipe 47 can be prevented.

Further, since each member is made of a hard vinyl chloride resin, and each connecting portion can be easily and surely connected by fitting and bonding, an inflow port 36 or an outflow port 38 is pierced with a hole saw or the like, and seal packing is performed. This eliminates the need for complicated work such as fixing the drain pipe 37, thereby improving workability and improving work efficiency, and preventing water leakage or intrusion.

Since the drainage basin body 31 and the trap tube 41 are rotatably connected, the trap tube 41 can be freely rotated in accordance with the piping at the installation site, and the workability can be improved.

In this embodiment, the cleaning port 32 of the drainage basin main body 31 and the soil reservoir 33 have substantially the same diameter, and the drainage basin main body 31 has a substantially cylindrical shape. However, as shown in FIGS. In addition, one side portion of the soil reservoir portion 33 is concavely formed in a curved surface shape, and an outlet 52 that opens downward is formed on the upper surface of the recess 51, and the inner end A of the outlet 52 is a cleaning port. It can also be located inside the peripheral part B of 32. By forming the outlet 52 in this manner, the inside of the trap tube 41 can be easily cleaned by a cleaning tool inserted from the cleaning port 32 of the drainage basin main body 31. Therefore, there is no need to provide the cleaning port 46 above the other end of the trap tube 41, and this trap tube 41 can be connected to the drainage pipe 47 on the downstream side via the elbow pipe 55, so that piping work can be facilitated. . Further, when the outlet 52 is formed in this manner, the core of the mold of the drainage basin body 31 can be pulled out from above and below, thereby simplifying the shape of the die and reducing the production cost of the drainage basin device with trap. Can be reduced.

Further, instead of forming the concave portion 51 on one side of the reservoir portion 33 as described above, the reservoir portion 33 is formed into a cylindrical shape having a diameter smaller than that of the cleaning port 32, and is biased toward the lower portion of the cleaning port 32. The same effect can be obtained by forming them in the center.

In each embodiment, the drainage basin main body 31 is used.
The inflow port 36 and the outflow port 38 are eccentric only in the vertical direction and are formed opposite to each other. However, as shown in FIG. 4, the inflow port 36 and the outflow port 38 are also offset in the horizontal direction. By forming the drainage flow path, the flow path of the drainage is bent and extended,
It is possible to prevent the earth and sand flowing in from the tank from flowing out directly from the outlet 38, and to separate the earth and sand more reliably and deposit the earth and sand in the reservoir 33.

In each embodiment, the drainage basin body 31 is used.
The trap tube 41 is rotatably connected to the outflow port 38, but the end of the outflow port 38 is simply a receiving port.
41 may be bonded and fitted.
