[Effect] The lid can be easily set according to the slope and height of the ground surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning port for a sewage basin in which a lid can be set on the upper end portion of a cleaning port tube according to the inclination and height of the ground surface.

[0002]

2. Description of the Related Art When a lid is set on the upper end of a cleaning port pipe that has risen upward from a sewage basin, not only does it look bad if the lid does not match the slope of the ground surface or the height,
There is a risk of tripping over the lid and falling or being hurt and injured. Therefore, various methods have heretofore been proposed in which the lid is set according to the inclination of the ground surface and the height. For example, Japanese Utility Model Application Laid-Open No. 5-87087 proposes a cleaning port that adjusts the inclination gradient and height of a lid holding cylinder by adjusting the amount of an adjuster bolt so that the lid is flush with the ground surface.

[0003]

However, in this conventional cleaning port, the adjuster bolt is embedded in the pipe wall of the lid holding cylinder so as to penetrate in the axial direction, so that the lid holding cylinder is inevitable. In addition to being inconvenient to handle, the tube wall was thick and heavy, and cost increase was inevitable.

The present invention has solved the above problems and provides a cleaning port for a sewage basin which can be provided at a low cost and has excellent workability, and the lid can be easily set according to the inclination and height of the ground surface. It is provided.

[0005]

According to the cleaning port of the present invention, a lid holding cylinder is loosely fitted to an upper end portion of a cleaning port pipe which is erected upward from a sewage basin via a rubber ring, and A lid receiving part is detachably attached to a lid receiving part formed by expanding the upper end part of the lid holding tubular body, and an adjuster bolt is hung from an appropriate position on the outer peripheral part of the lid receiving part of the lid holding tubular body. At the same time, the adjuster bolt is screwed with a support member locked to the upper end of the cleaning port tube.

[0006]

[Operation] During piping installation at the site, if the lid holding cylinder loosely fitted to the cleaning port pipe is lifted by hand and the adjustment amount of the adjuster bolt hanging from the proper position on the outer periphery of the lid receiving part is adjusted, The lid attached to the part is flush with the ground surface.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing an embodiment of the present invention, and FIG. 2 is a cross-sectional view of an essential part of a state in which a lid holding cylinder is supported at a predetermined position. Reference numeral 1 in the drawing is a sewage stub and 2 is a cleaning port. A tube, 3 is a lid holding cylinder, 4 is a rubber ring, 5 is a lid, 6 is an adjuster bolt, and 7 is a support member.

The sewage basin 1 is integrally formed by injection molding a synthetic resin such as vinyl chloride resin, and a drainage groove 13 is provided at the bottom of a tub body 10 having a bottomed cylindrical shape with an upper opening. Has been. A connection port 11 for the inflow pipe and a connection port 12 for the outflow pipe are provided on the side wall of the basin body 10 in communication with the drainage groove 13.

The sewage basin 1 is buried in the ground, and the sewage basin 1 is installed at the bottom of the excavation groove formed by excavating the ground, and then the sewer pipe P is connected to each of the connection ports 11 and 12. Connect the upstream and downstream ends. On the other hand, the cleaning port tube 2 is inserted into the upper connection port of the main body of the sluice and the cleaning port tube 2
The lid holding cylinder 3 is loosely fitted to the upper end of the lid via a rubber ring 4 so as to be vertically movable.

The lid holding cylinder 3 is formed by enlarging one end of a short tube having a diameter slightly smaller than the inner diameter of the cleaning port tube 2 to form a lid receiving portion 31, and the lid receiving portion 31 has a lid. The body 5 is detachably attached. In addition, 2 is provided on the outer peripheral surface of the other end of the lid holding cylinder 3.
Book ridges 32 are provided, each ridge 32,
The rubber ring 4 that is in close contact with the inner peripheral surface of the cleaning port tube 2 between 32
Is installed.

An adjuster bolt 6 is penetrating through the outer peripheral portion of the lid receiving portion 31, and a lower portion of the adjuster bolt 6 is screwed with a supporting member 7 locked to the upper end portion of the cleaning port tube 2. ing. The adjuster bolt 6 is preferably hung from a plurality of places that divide the circumference into two equal parts or three equal parts. By adjusting the tightening amount of the adjuster bolt 6, the inclination gradient and height of the lid holding cylinder 3 can be adjusted. It can be adjusted. Reference numeral 61 is a ring member that supports the adjuster bolt 6 from below the lid receiving portion 31.

The support member 7 can be formed in any suitable shape, but as shown in FIG. 2, a support portion 71 locked to the upper end portion of the cleaning port tube 2 and a screw portion 72 with which the adjuster bolt 6 is screwed. If the structure is such that the support member 7 is connected via the stepped portion 73, the support height of the lid holding cylinder 3 can be adjusted in a wide range only by turning the support member 7 upside down as shown by the broken line in the figure. There is.

Next, the procedure for adjusting the inclination angle and the height of the lid holding cylinder 3 and the construction work will be described. First, manually lift the lid holding cylinder 3 loosely fitted to the upper end of the cleaning port tube 2,
While maintaining the lid receiving portion 31 flush with the ground surface, the tightening and tightening of the adjuster bolt 6 is adjusted to bring the support member 7 into contact with the upper end surface of the cleaning port tube 2. At this time, the head of the adjuster bolt 6 may be turned by a screwdriver or the like to adjust.

In this way, the lid receiving portion 31 of the lid holding cylinder 3
After adjusting the tilt angle and height of the lid holding cylinder 3 with the adjuster bolts 6 and the support members 7 that are hung from 2 to 3 places, the lid 5 is attached to the lid receiving portion 31. Therefore, as shown in FIG. 1, backfill with earth and sand is carried out, and the ground surface is paved with concrete, asphalt, or the like. Then, the lid holding cylinder 3 is fixed with concrete, asphalt or the like, and the construction work is completed.

[0015]

As described above in detail, since the present invention can make the lid holding cylinder light in weight, it can be provided at a low cost and can be easily handled during the construction work. Further, the lid holding cylinder body loosely fitted in the cleaning port tube is lifted by hand, and the tightening / adjustment of the adjuster bolt hanging from the outer peripheral portion of the lid receiving portion of the lid holding cylinder body is simply adjusted. Since the tilt angle and height can be adjusted, on-site construction work can be performed extremely easily.
