Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an above-ground opening (hereinafter referred to as a cleaning device) such as a sewage masu, a rainwater masu, and a manhole (hereinafter referred to as sewage masu) provided in the ground.

[0002]

[Prior Art]

 The above-mentioned sewage masu is installed at the connection part of the drainage pipe buried underground, the bent part of the drainage pipe, or the drainage pipe part at the boundary of the site. FIG.

The sewage masu 1 includes a sewage masu body 3 connected to the drainage pipe 2, a rising pipe 4 connected from the sewage masu body 3 to the surface of the earth, and a detachable device attached to the upper end opening of the rising pipe 4. It is composed of a transparent lid 5.

However, the upper surface of the lid 5 needs to be flush with the ground surface. Therefore, the riser pipe 4 is made of vinyl chloride and cut to the required length at the installation site and attached to the main body 3 for sewage. Then, by attaching a cleaning port device 7 composed of a vinyl chloride lid receiving frame 6 and a vinyl chloride lid 5 detachable to the opening of the lid receiving frame 6 to the upper end portion of the rising pipe 4, The upper surface of the lid of the sewage masu installed is made to match the ground surface.

The above-mentioned cleaning port device 7 has an advantage that it is easy to adjust the height of the lid and install a sewage mist at the site, and it is made of vinyl chloride so that it is suitable in terms of price. ing.

[0006]

[Problems to be solved by the device]

 However, in the above-mentioned conventional cleaning port device 7, the portion exposed on the ground surface is made of vinyl chloride, and therefore wear becomes conspicuous in a parking lot or a road with a high traffic volume. In particular, when the upper surface of the lid 5 is projected from the ground surface, there is a problem that the lid receiving frame 6 and the edge of the lid 5 are scratched and scratched by the tire when the vehicle passes and eventually develop into damage.

This invention was made in order to solve the above-mentioned problems of the prior art, and the height of the lid of sewage drain etc. can be easily matched with the ground surface, and it is worn by a vehicle or the like. -Can prevent damage and has excellent durability. Moreover, it is an object of the present invention to provide a cleaning port device that suppresses a slight increase in cost.

[0008]

[Means for Solving the Problems]

 For this reason, the cleaning port device according to the present invention is equipped with a highly wear-resistant lid receiving frame connected to the upper part of the rising pipe connected to the main body of the sewage mast, and detachably attached to the lid receiving frame. It is an object of the present invention to achieve the above object by a structure characterized by comprising a lid and a ring having high wear resistance attached to the upper edge portion of the outer peripheral surface of the lid.

[0009]

[Action]

 With the above configuration, by cutting the rising pipe to a required length and connecting the lid receiving frame, the upper edge of the lid receiving frame and the upper surface of the lid can be easily matched with the ground surface.

The lid receiving frame and the ring attached to the upper edge portion of the outer peripheral surface of the lid have high abrasion resistance, and thus will not be worn for many years, and will not be scratched or scratched by the tires of the vehicle. Excellent durability.

[0011]

【Example】

 Hereinafter, a cleaning port device according to the present invention will be described with reference to examples. FIG. 1 is a sectional view of an embodiment of the present invention, in which the same or corresponding parts as those of the conventional cleaning port device are designated by the same reference numerals.

The cleaning port device 7 of this embodiment is provided with a highly wear-resistant lid receiving frame 6 which is connected to the main body of the waste water muffler or the like, or is connected to the upper end portion of the rising pipe 4 directly connected to the drainage pipe, and the lid receiving device. It is composed of a lid 5 which is detachably attached to the frame 6, and a ring 8 having high wear resistance which is attached to the upper edge portion of the outer peripheral surface of the lid 5.

The lid receiving frame 6 and the wear resistant ring 8 are made of resin concrete, glass fiber reinforced plastic (GFRP) or the like, which can obtain high wear resistance. When the lid 5 is attached to the lid receiving frame 6, the upper edge of the lid receiving frame 6 and the upper edge of the ring 8 are aligned with each other, or the dimension is determined so that the upper edge of the ring 8 is slightly higher. Therefore, the upper edge portion of the ring 8 and the upper surface of the lid 5 have substantially the same height.

The cleaning port device 7 of this embodiment is connected to the main body of the wastewater tank so that when the lid receiving frame 6 is connected to the rising pipe 4, the upper edge of the lid receiving frame 6 matches the ground surface. The pipe 4 or the rising pipe directly connected to the drainage pipe is dimensioned and cut, the lid receiving frame 6 is bonded and connected, and the lid 5 with the ring 8 is covered to close the opening of the lid receiving frame 6. It's something.

With the above configuration, the lid receiving frame 6 is connected to the rising pipe 4 cut to a length required at a work site or the like, so that the lid receiving frame 6 and the lid 5 are easily aligned with the ground surface. be able to.

Further, since the lid receiving frame 6 and the ring 8 attached to the upper edge portion of the outer peripheral surface of the lid 5 have high wear resistance, they will not be worn for many years, and the ring 8 will be It is not scratched or damaged and has excellent durability. Since the lid 5 can be made of vinyl chloride or the like as in the conventional case without impairing the above-mentioned effects, a slight increase in cost can be suppressed.

[0017]

As described above, according to the present invention, by connecting the lid receiving frame to the rising pipe that is cut to a required length at the work site, the upper edge of the lid receiving frame and the lid The upper surface can be easily matched with the ground surface.

Further, the lid receiving frame and the ring attached to the upper edge portion of the outer peripheral surface of the lid have high abrasion resistance, and therefore do not wear for many years, and are scratched and damaged by the tires of the vehicle. No, it has excellent durability. Note that the lid can be formed of vinyl chloride or the like as in the conventional case without impairing the above-mentioned effects, so that a slight increase in cost can be suppressed.
