BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, a first embodiment shown in FIGS. 1 to 7 will be described. Reference numeral 1 denotes a cylindrical valve housing case 4 made by combining an inner cylinder 2 made of synthetic resin and an outer cylinder 3 made of synthetic resin. The valve housing 1 is filled with a filling material 5 such as resin concrete from an inlet (not shown) provided at an upper end or a lower end. The valve housing 1 is a water pipe or a lower water pipe embedded in the ground. At a mounting portion of an on-off valve (not shown) attached to a water pipe or a fire hydrant, a plurality of stages are stacked and buried in the ground to form a space above the on-off valve mounting portion to operate the on-off valve from the ground. A lift lid 6 made of casting is placed on the upper end of the valve housing 1 at the uppermost stage in the valve housing arrangement portion. In the embodiment shown in the drawings, the valve housing 1 and the lift lid 6 have a circular planar shape. The lifting / lowering lid 6 is fitted into a concave portion 7 formed at the upper end of the uppermost valve housing 1 and is positioned and has a female guide 8 formed on an inner surface thereof. A male screw part 10 meshing with the female screw part 8 is formed on the outer surface, and a cylindrical main body 11 screwed into the cylindrical guide part 9 from above, and a cylindrical main body 11 for closing an upper end opening 11a of the cylindrical main body part 11. A lid portion 12 is received by a step portion 11b on the inner surface of the upper end portion 11a of the portion 11, and the tubular guide portion 9, the tubular main body portion 11, and the lid portion 12 are made of a casting. The upper end surface of the tubular main body 11 and the upper end surface of the lid 12 are flush.
[0009]
After the casting lid 6 is made at the factory, the upper end of the tubular main body 11 and the lid 12 received by the step 11b are protected by a cap 13 made of synthetic resin. The upper end of the cylindrical main body 11 is formed so as to protrude outward. The cap 13 has a circular plate portion 13a forming an upper surface and a circular plate 13a which covers the upper end protruding portion 14 from above and from the side. And a side plate portion 13b provided continuously downward from the outer periphery of the plate portion 13a, and at the lower end of the side plate portion 13b, claw pieces 13c are integrally provided at appropriate circumferential intervals so as to be inclined inward. The piece 13c is configured to engage with the lower side of the upper end overhang portion 14. In the drawing, eight claw pieces 13c are provided at the lower end of the side plate 13b at appropriate intervals in the circumferential direction. Further, a V-shaped cut groove portion 13d is formed over the entire periphery near the outer periphery of the circular plate portion 13a forming the upper surface of the cap 13.
[0010]
In the above configuration, when the lift lid 6 is placed on the upper end of the uppermost valve casing 1 in the valve casing installation portion in which the valve casings 1 are stacked and buried in the ground in a plurality of stages, the cylindrical shape of the lift lid 6 The upper end overhanging portion 14 of the main body 11 is covered with the cap 13, and after the lifting lid 6 is placed on the upper end of the uppermost valve housing 1, soil is placed around the valve housing 1 and the lifting lid 6. Then, asphalt pavement work is performed on the ground surface with the cap 13 attached to the lifting lid 6. After the asphalt pavement work is completed, a plate 13a that finally forms the upper surface of the cap 13 is inserted into one of the cut grooves 13d with a cutter or the like, and the plate 13a is cut from that location along the cut groove 13d. As a result, the upper end surface of the cylindrical main body 11 of the lifting lid 6 and the upper end surface of the lid 12 are exposed to the ground. The remaining side plate portion 13b and claw piece 13c from which the plate portion 13a has been cut out are buried and killed in the soil.
[0011]
By the way, in the embodiment described above, the cap 13 is made of a synthetic resin, and when the elevating lid 6 is placed on the upper end of the valve housing 1 at the uppermost stage, the display on the upper surface of the lid 12 can be seen from above the cap 13. Preferably, the cap 13 is transparent. If the cap 13 does not need to be transparent, it may be made of metal.
[0012]
Further, in the embodiment shown in the drawings, the valve housing 1 and the elevating lid 6 have a circular planar shape, and accordingly, the cap 13 also has a circular planar shape. However, the second embodiment shown in FIGS. It is also possible to form a cap 16 having a substantially rectangular planar shape so as to correspond to the lid 15 placed on the upper end of a substantially rectangular valve housing as in the embodiment. The cap 16 according to the second embodiment has an upper surface formed so as to cover from above a lid 15 composed of a cylindrical main body 17 and a lid 18 fitted into the upper end opening 17a of the cylindrical main body 17. A plate portion 16a, a side plate portion 16b provided continuously downward from the outer periphery of the plate portion 16a, and a claw piece 16c inserted into a gap 19 at a corner portion between the tubular main body portion 17 and the lid portion 18. It has. The gap 19 is slightly larger than the corner of the lid 18 at the corner of the cylindrical main body 17 and forms an arc-shaped concave portion 19a on the inner surface. The gap 19 is fitted in the cylindrical main body 17 when the lid 18 is fitted. The planar shape is formed between the arc-shaped inner surface of the concave portion 19a and the arc-shaped outer surface of the corner portion of the lid portion 18 so as to be slightly arcuate downward and inward. The claw piece 16c inserted into the gap 19 has a horizontal cross-sectional shape formed in a straight line or an arc shape, but this claw piece 16c is formed at right angles to the plate portion 16a without being inclined. Further, a V-shaped cut groove 16d is formed over the entire periphery near the outer periphery of the circular plate portion 16a forming the upper surface of the cap 16.
[0013]
Therefore, the cap 16 in the second embodiment also covers the lid 15 when the lid 15 is placed on the upper end of the valve housing, but the claw piece 16c formed at a right angle to the plate portion 16a has Since the claw piece 16c is pressed into the inner surface of the gap 19 because it is inserted into the gap 19 that is slightly inclined inward downward, the cap 16 can be prevented from floating. Then, after the lid 15 is placed on the upper end of the valve housing, soil is put around the valve housing and the lid 15, and asphalt paving work is performed on the ground surface with the cap 16 attached to the lid 15. After the asphalt pavement work is completed, a plate or the like that finally forms the upper surface of the cap 16 is inserted into one of the cut grooves 16d with a cutter or the like, and the plate 16a is cut from the location along the cut groove 16d. As a result, the upper end surface of the cylindrical body 17 of the lid 15 and the upper end surface of the lid 18 are exposed to the ground. At this time, the claw piece 16c is pulled out of the gap 19. The remaining side plate portion 16b from which the plate portion 16a has been cut may be buried and killed in the soil. However, in some cases, the side plate portion 16b may be removed from the soil.
[0014]
【The invention's effect】
