Next, the operation of the trap-equipped box device of the embodiment will be described.

Drainage containing earth and sand from an outside sink installed outside the building or the like flows into the inside of the container 11 provided in the cell body 1 from the inlet 6 of the cell body 1.
Then, the drainage containing the earth and sand,
It is stored up to the position of the overflow portions 13, 13 of the container 11 installed in the container. At this time, a substance having a high specific gravity, such as earth and sand, contained in the drainage precipitates and accumulates inside the container 11.

When the water level of the wastewater stored in the container 11 increases, only the supernatant of the wastewater containing soil and the like, that is, only the wastewater overflows from the overflow portions 13, 13 of the container 11 and It flows out to the overflow ports 14 and 14 of 1. Further, it flows to the inlet 10 of the elbow body 8, passes through the inside of the elbow body 8, and flows out to the outlet 7.

When drainage containing earth and sand flows into the inside of the basin 1 from the inlet 6 with a strong force, the wastewater containing earth and sand hits the concealing wall 12 of the container 11.
It rebounds to the inflow port 6 side, and the water force decreases. For this reason, substances having a high specific gravity, such as earth and sand, contained in the drainage surely precipitate and accumulate in the container 11.

Further, when a large amount of a substance having a high specific gravity such as earth and sand is deposited inside the container 11, the handle 16 of the container 11
The container 11 is taken out of the box body 1 to remove the substance deposited inside the container 11.

For this reason, the outflow of earth and sand to the outlet 7 of the basin body 1 can be reduced,
Clogging of the outlet 7 of the basin body 1 and the drain pipe connected to the outlet 7 can be reliably prevented.

When the container 11 is installed in the box body 1, the overflow portions 13, 13 of the container 11 are arranged at a position lower than the lowest position of the inlet 6 of the box body 1. It is configured. For this reason, drainage including earth and sand flowing from the inlet 6 of the basin body 1 efficiently flows into the container 11. Therefore, soil and the like contained in the wastewater can be efficiently removed in the container 11.

The width of the inlet 6 is not less than the inner diameter La.
A substantially planar shielding wall 12 having Le and a height dimension is placed in a container 11.
Therefore, even if the drainage containing soil and the like flows into the basin body 1 with a strong water force, the drainage containing the soil hits the shielding wall portion 12 of the container 11 and is located on the inlet 6 side. The water bounces off and the water pressure declines. Therefore, the wastewater that has flowed in with a strong water force can be sufficiently repelled by the shielding wall portion 12, so that sediment and the like contained in the wastewater can be surely settled and deposited inside the container 11.

Further, the distance Ld at the inlet 10 of the elbow body 8 is the inner diameter of the outlet 9 of the elbow body 8.
Since the outlet 9 is formed in a flat shape with a diameter smaller than Lc, the container 11 with respect to the inside of the

Can be removed from the outlet 7 of the main body 1. Therefore, the inside of the elbow body 8, the outlet 7 of the box body 1, the drain pipe connected to the outlet 7, and the like can be easily cleaned.

Since the water level of the wastewater stored in the main body 1 is always at the same height as the lowest position of the outlet 7, the wastewater stored in the inlet 10 of the elbow body 8 The odor of the sewage main can be sealed with water. Therefore, since the elbow body 8 functions as a trap, it is possible to prevent the odor from leaking into the inside of the main body 1.

Further, an extra operation is required such that a hole is formed in a portion corresponding to the inflow port 6 and the outflow port 7 with a hole saw or the like, and the elbow body 8 is fitted into this hole via a packing seal. In comparison with the conventional trap-equipped box device, in the above embodiment, the inflow port 6 and the outflow port 7 are formed integrally with the box body 1, so that only the elbow body 8 is fitted into the outflow port 7. Good. For this reason, the mounting operation when the apparatus main body is installed becomes easy.

Further, in comparison with the conventional trap-equipped box device in which drain pipes and the like are easily pulled out, in the above-described embodiment, the cell body 1
A drain pipe is firmly fitted and fixed to each of the inflow port 6 and the outflow port 7 which are protrudingly provided. Therefore, the main body 1
Of the drain pipe to the inflow port 6 and the outflow port 7 can be reliably prevented.

Further, in the elbow body 8, the outlet 9 of the elbow 8 is fitted into the outlet 7 of the cell body 1, and the inlet 10 of the elbow 8 is connected to the cell 1 and the container 11. Shield wall 12

In the above-described embodiment, the elbow body 8 in which the inflow portion 10 is formed in a flat shape and the inner portion 10b is formed in a substantially flat shape has been described. For example, as shown in FIG. 3, the inlet portion 10 of the elbow body 8 has a substantially cylindrical shape, that is, the distance Ld at the inlet portion 10 of the elbow body 8 is equal to the distance Ld at the outlet portion 9 of the elbow body 8. While being substantially the same as the inner diameter Lc,
The inner portion 10b of the inlet 10 may be formed in a substantially arc shape. By configuring the elbow body 8 in this manner, the container 11 is formed such that the center of the side portion 11a of the container 11 is formed in a concave arc shape corresponding to the shape of the inner portion 10b of the elbow body 8, and the shielding wall portion is formed. 12 is also formed in a substantially arc shape.
