[Industrial applications]

 The present invention relates to a drainage trough used in the middle of a drainage pipe.

[0002]

[Prior Art]

 In recent years, with the modernization of cities and residential areas, domestic sewage from kitchens and toilets is drained through drainage basins buried in the ground into sewer pipes, from which it is transported to sewage treatment plants in an appropriate manner. The system for burrs is becoming popular. Such drainage basin is installed at the connection part of the drainage pipe buried in the ground, the bent part of the drainage pipe, the drainage pipe at the boundary of the site, and the like. In addition, since there are more and more opportunities to install pipes in narrow places where the installation space is restricted, small drainage that can connect a stand-up pipe with a cleaning port (or inspection port) diameter of 100 to 250 mm. However, it is increasingly used. For the pipes and small drainage pipes used in these conventional drainage pipes, molded products made of synthetic resin such as vinyl chloride resin are used because of their lightness and ease of construction, and the connection of these pipes is made by bonding. The airtightness is highly maintained by the plug-in connection with the agent or packing. Figure 3 shows a cutaway view of such a small drainage basin in use.

In the small drainage basin A, drainage pipes 4 and 5 are connected to an inflow port 11 and an outflow port 12 on the side of the main body 1, and a rising pipe 2 of a predetermined length is attached to an upper end opening 13 of the main body 1. Is connected, and the lower portion of the cleaning port 3 having a lid (not shown) fitted in the upper opening of the rising pipe 2 is connected. Further, the inner peripheral surface of the rising corner portion 14 of the main body 1, which is connected from the inflow port 11 and the outflow port 12 to the upper end opening portion 13, has a rounded curved structure.

In addition, in the above small drainage basin, the diameters of the drainage pipes 4 and 5 connected to the inflow port 11 and the outflow port 12 are often smaller than the diameter of the cleaning port (or inspection port) 3 and, in addition, rises. Generally, the height of the tube 2 is often set to about 300 mm, and it may be set to a height higher than that.

When the inside of the drain pipe or the drainage basin is cleaned using the cleaning port 3 of the small drainage basin, a cleaning jig 6 as shown in FIG. 3 is used. This jig 6 has a head portion 60 such as a spiral portion or a jet water jet nozzle provided at the tip of a wire material having a strong elasticity such as a steel wire and having a spring property. The head 60 is moved forwards and backwards by removing the solids and the like adhering to the inner surface of the drainage pipe by inserting it from the inside of the drainage pipe 3 and guiding it into the drainage pipes 4 and 5.

[0006]

[Problems to be solved by the device]

 However, in the conventional small-sized drainage basin, the diameter of the cleaning port 3 is as small as 100 to 250 mm, the diameters of the drainage pipes 4 and 5 are smaller than the diameter of the cleaning port 3, and the height of the rising pipe 2 is also increased. Is set to about 300 mm or more, and therefore, when inserting the head 60 of the cleaning jig 6 into the drainage pipes 4 and 5, the rising corner portion 14 has a rounded inner peripheral surface. Even if it was, it could not be inserted easily, and I had to force it.

Further, when the head 60 of the cleaning jig 6 is inserted into the drain pipes 4 and 5, the wire material hits the rising corner portion 14 strongly, and when the wire material is taken in and out for cleaning, the wire material and the rising corner portion There was a problem that the main body was scratched further by rubbing against 14 and it was destroyed in the worst case.

Therefore, in order to solve the above-mentioned problems, Japanese Patent Laid-Open No. 3-219194 discloses that a lower end inner surface of an upper end opening of a main body and a base end side surface of an inflow port and an outflow port are provided. A drainage basin is disclosed that is connected through a downwardly flared inner surface formed on the outer wall of the body. However, even if such a method is used, the insertability of the cleaning jig and the loading and unloading of the wire will be easier, but the wire will rub against the inner surface of the bottom spreading shape of the body, and the body will be further damaged. There is no change, so it has not been completely resolved.

The present invention is a drainage that solves the above problems, and by making the main body structure different from the conventional one, it does not hinder the insertability of the cleaning jig and the insertion and removal of the wire rod, and The purpose of the present invention is to provide a drainage body in which the main body is not damaged even when a jig is inserted or wires are taken in and out.

[0010]

[Means for Solving the Problems]

 The drainage basin of the present invention comprises a main body having an inflow port, an outflow port, and an upper end opening, a rising pipe connected to the upper opening, and a cleaning port connected to the upper part of the rising pipe. The drainage basin is characterized in that at least the inner peripheral surface of the rising corner of the main body, which is connected from the inflow port and the outflow port to the rising pipe, is formed of a wear resistant member.

[0011]

[Action]

 With the drainage basin of the present invention, when cleaning the inside of the drainage pipe or drainage basin using the cleaning port, the wire rod made of steel wire of the cleaning jig will hit the rising corner strongly when inserted and the wire rod Even if the rising corner portion and the wire material rub strongly against each other by taking in and out, since the inner peripheral surface of the rising corner portion is formed of a wear resistant member, the main body will not be damaged further.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a drainage basin according to an embodiment of the present invention in use. In this drainage basin B, a drainage pipe 4 led out from a kitchen or a toilet is connected to an inlet 11 on the side of the main body 1, and a drainage pipe 5 connected to a public sewer main, for example, is connected to an outlet 12. The drain pipes 4 and 5 are usually vinyl chloride resin pipes having a small diameter of 75 to 150 mm.

The main body 1 is made by injection molding of vinyl chloride resin, a rising pipe 2 of a predetermined length is connected to the upper end opening 13, and a lid (not shown) is attached to the upper opening of the rising pipe 2. The lower part of the fitted cleaning port 3 is connected.

Then, wear resistant members 15 and 16 are formed integrally with the main body 1 by insert molding on the inner peripheral surface of the rising corner portion of the main body 1, which is connected from the inflow port 11 and the outflow port 12 to the rising pipe 2. Has been done. That is, the cut end face shape along the line aa is semicircular or semielliptical. However, it may be formed in a ring shape over the entire circumference of the inner surface of the rising corner portion, and as in this embodiment, at least the inlet 11 and the outlet 12 are connected to the rising pipe 2 The rising corner of the main body 1 The abrasion resistant member 15 may be formed on the inner peripheral surface of the part. At the time of insert molding, in order to improve the adhesion between the resin of the main body 1 and the abrasion resistant member 15, the abrasion resistant member 15 is provided with a concave groove 20.

Further, in this case, the material of the abrasion resistant member 15 is metal, but polyacetal, ultra high molecular weight polyethylene, FRP, or ceramics may be used. In this embodiment, the wear resistant member 15 is integrally formed with the main body 1 by insert molding, but after the main body 1 is molded, the wear resistant member 15 is inserted from the upper end opening 13. Then, it may be formed on the inner peripheral surface of the rising corner portion with an adhesive or the like.

Further, the inner peripheral surface of the abrasion resistant member 15 is a flat surface, and the cleaning jig 6 is inserted through the cleaning port 3 as shown in the figure to drain the drain pipes 4, 5 and the main body for draining. When cleaning the inside of 1, the wire of the jig 6 can be smoothly inserted along the surface of the wear-resistant member 15, and the surface contacting the wire is the wear-resistant member 15. Since it is covered, even if the wire rod is put in and taken out and cleaned and the wire rod and the rising corner portion rub strongly against each other, there is no fear that the corner portion will be damaged or destroyed.

Further, the inner peripheral surface of the abrasion resistant member 15 may have a curved structure with roundness as in the conventional case. FIG. 2 shows a sectional view of a drainage basin in use according to another embodiment of the present invention. In this drainage basin C, the wear resistant members 17 and 18 are connected in a substantially circular ring shape from the inflow port 11 and the outflow port 12 to the rising pipe 2. The inner surface of the rising corner of the main body 1 and the inflow port 11, It is similar to the embodiment of FIG. 1 except that it is also formed continuously on the inner peripheral surface of the outlet 12. In this case, not only the inner peripheral surfaces of the rising corners but also the inner peripheral surfaces of the inflow port 11 and the outflow port 12 are protected by the wear resistant member, so that the durability is further improved.

The embodiments of the present invention have been described in detail above with reference to the drawings. However, the specific configuration is not limited to these embodiments, and there are design changes and the like without departing from the scope of the present invention.
