Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a square used for residential lots, etc.

[Conventional technology and its problems]

As is well known, the Enforcement Regulations of the Sewerage Law stipulates that pipes should be installed at starting points of pipe passages, confluence points of pipe passages, bending points, and places where slope, pipe diameter, or pipe type changes. Therefore, in a typical home, the place where the drainage branch pipe from the kitchen, bathroom, washing machine, toilet, etc. joins the drainage pipe inside the residential property,
Furthermore, a basin is required at the junction of the residential drainage pipe and the public drainage main pipe. The basin is constructed such that the residential drainage pipe and the connection pipe to the public drainage main pipe are located on substantially the same horizontal plane, except for the flow gradient.

However, if there is a considerable head difference between the public drainage main pipe and the drainage pipe within the residential area, for example in a residential area where the land is developed in a tiered manner, the basin placed there may be located on a substantially horizontal plane, and the inlet pipe may If the pipe is configured to be branched into an outflow pipe and an outflow pipe, it will be necessary to further join the connecting pipe downward using a bend or the like, which is inconvenient.

Therefore, in such a case, a conventional pipe sieve uses, for example, a sieve as shown in FIG. 8. In other words, when A is a residential land and B is a public land, and there is a considerably large head difference between the public drainage main pipe (not shown) and the residential land drainage pipe C, the side wall of the large diameter pipe 1 of 300 mmφ A basin 1 is used which constitutes a socket 2 for a drainage pipe in a residential property, and has a narrowed bottom 3 and a downward socket 4 communicating with a public drainage main at the lowest part. In addition, 5, 5 is the adjuster cylinder of the same length as the inspection and cleaning socket 6 of the box 1, 7 is the lid,
8 indicates the foot of the box.

However, such a large-diameter box 1 is not suitable for narrow residential areas, and since the necessary functions of the box are inspection and cleaning, it has a large diameter and is also equipped with legs 8. Costs are also rising due to over-quality.

On the other hand, instead of such a large-diameter box 1, it may be possible to use an LT joint with a minimum diameter of 150 mmφ, which is the minimum diameter necessary for inspection and cleaning, but if such an LT joint is used, the problems with the large-diameter pipe 1 can be solved. Although this can be solved, the standard diameter of the drainage pipe C in the residential area is 75mmφ~
Considering the current situation where 100mmφ ones are used,
When joining such an LT joint and a residential drainage pipe, it is necessary to use a so-called increaser to adjust the gap between the two.

[Means for solving problems]

Therefore, the present invention was devised in an attempt to solve the problems of the conventional technology at once.The gist of the invention is that the cylindrical basin body has a diameter of approximately 150 mm upward.
At least one socket for an inspection and cleaning pipe with a diameter of ~200mmφ placed horizontally, and a socket for a residential drainage pipe with a standard diameter for residential drainage pipes, and a socket for a drop pipe leading downward to the public drainage main. In addition to making the diameter of the drop pipe socket smaller than the diameter of the inspection and cleaning pipe socket in each of the pipes used for residential land, etc., which have openings, A pipe wall for use in housing lots, etc., characterized in that a part of the pipe wall of the main body is made vertical, thereby forming a step-like abutting part on the pipe wall extending the outlet for the drainage pipe in the residential property.

〔Example〕

The structure and operation of the present invention will be explained in detail with reference to first, second and third embodiments shown in the accompanying drawings.

FIG. 1 is a longitudinal sectional view of the first embodiment of the present invention, FIG. 2 is a sectional view taken from X to X in FIG. 1, FIG. 3 is a longitudinal sectional view of the second embodiment of the invention, and FIG. The figure is Y~ in Figure 3.
Y sectional view, FIG. 5 is a vertical sectional view of the third embodiment of the present invention, FIG. 6 is a sectional view from X to X of FIG. 5, and FIG. 7 is a sectional view of another usage example of the present invention. FIG. 8 shows a sectional view of a conventional example.

Therefore, these examples are, for example, synthetic resin basins for residential land developed in a tiered manner, and there is a considerably large head difference between the residential land drainage pipe and the public drainage main pipe. It is convenient for the basin used at the confluence point.

Now, in a typical basin, the socket that joins the inflow and outflow pipes is opened in a substantially horizontal plane, whereas the basin of this embodiment also has a socket opened at the bottom of the basin, It was designed to allow sewage to flow out from here, and could be called a drop basin.

Therefore, as shown in FIGS. 1 and 2, the basin of the first embodiment has a cylindrical basin main body 10, with an inspection and cleaning pipe socket 11 facing upwards and a housing area drainage pipe socket horizontally. A drop pipe socket 13 for draining the mouth 12 downward into a public drainage main pipe in a drop shape is molded integrally by injection molding.

Here, the inspection and cleaning pipe socket 11 has a diameter of
It is sized to fit a 150mm diameter peep tube, so that inspection and cleaning will not be a problem.
In addition, the residential drainage pipe socket 12 that connects the residential drainage pipe (see Figure 8), where the drainage branch pipes (not shown) from the kitchen, washroom, washing machine, toilet, etc. join, is used to As standard for pipes, diameter 75mm~
The size is large enough to join a 100mmφ pipe. Further, the drop pipe socket 13 has a diameter of 75 mm to 100 mmφ, which is the same diameter, since there is only one in-house drainage pipe flowing into the basin in this embodiment.

Therefore, these sockets 11, 12 and 13
are arranged in the box body 10 as follows. That is, as shown in FIG.
Since the pipe wall 14 on the opposite side of the in-house drainage pipe socket 12 is made vertical, the inspection and cleaning pipe socket 1
1 center line a and the center line b of the drop pipe socket 13
It becomes eccentric when viewed from the first illustration. On the other hand, as shown in FIG.
5 and 15 have a popper shape having a symmetrical inclination to the center lines a and b, so the center lines a and b are coaxial when viewed from the second diagram.

As a result, as shown in FIG. 1, in the pipe wall of the basin body 10 extending the in-house drainage pipe socket 12, and also directly below the inspection and cleaning pipe socket 11, there is a stepped abutment area. 16 can be formed.

Note that the length l of the inspection and cleaning pipe socket 11 is shorter than the length of a normal regulated socket.

Since the box of this embodiment has the above-described configuration, if such a box is used in place of the conventional large-diameter box 1 shown in FIG. It is convenient for residential land. Furthermore, when inspecting and cleaning, even if the lid 7 is opened and an inspection mirror or flexible cleaning rod 18 is inserted, it will come into contact with the abutment part 16, making inspection easy. The rod 18 is conveniently curved so that it can be smoothly inserted into the residential drainage pipe.

Next, the second embodiment of the present invention will be described only in terms of its differences from the first embodiment. There are two pipe sockets, a first and second in-house drainage pipe sockets 12a and 12b, which are provided with their orientations changed at right angles.

The diameter of the first in-residential drainage pipe socket 12a is 100 mmφ, the diameter of the second in-residential drainage pipe socket 12b is 75 mmφ, and the diameter of the inspection and cleaning pipe socket 11 is
150mmφ, diameter of drop pipe socket 13 is 100mmφ
It is said that

Moreover, since the second residential property drain pipe socket 12b is provided on the left side when viewed from the first residential property drain pipe socket 12a of the pipe of the second embodiment, it can be referred to as a left side drop pipe. A right side drop box opposite to this can be considered, and a both side drop box can also be considered in the same way. Furthermore, by using a blind lid, these deformed boxes can be molded with the same mold.

Next, a third embodiment of the present invention will be described, which is similar to the first embodiment, with both hopper-shaped pipe walls 15 and 1 having symmetrical inclinations to the center lines a and b.
5, it is constructed with vertical tube walls 15a, 15a and steeply inclined tube walls 15b, 15b.

Next, as described above, the present invention is used as a so-called drop pit, but as shown in FIG. 7, it can also be used as a U-trap merging pit. That is, the figure shows a U-trap merging basin using the second embodiment, in which a U-trap 17 is joined to a drop pipe socket 13.

[Effect of idea]

According to this invention, a peep tube for inspection and cleaning can be
mm to 200 mmφ, which is convenient for narrow residential areas, etc., and the diameter of the drop pipe socket is smaller than the diameter of the inspection and cleaning pipe socket.
Since the pipe wall of the basin body at a position away from the outlet for residential drainage pipes is vertical, a stepped contact area is formed, and the flexible cleaning rod comes into contact with this contact area to conveniently clean the residential area. Can be inserted into the internal drain pipe.

Moreover, since we can produce pipes at a cost comparable to that of LT joints, we can provide inexpensive pipe weaving work.
