A box body 12 made of cast iron is attached to the upper portion of the frame body 11. As shown in FIG. 2, the box body 12 has a cylindrical body 13 fitted to the frame body 11 and a flange 14 that regulates the fitting depth at the lower end thereof. The box body 12 has a tubular portion 15 protruding upward, and a threaded portion 16 is formed on the inner circumference of the tubular portion 15. Next, an inner cylinder 18 having a threaded portion 17 that is screwed onto the threaded portion 16 and formed on the outer periphery is provided. Two protrusions 19 are formed on the upper portion of the inner cylinder 18 at symmetrical positions.
Both sides of these protrusions 19 are formed as edge portions 20. Further, a lid fitting portion 22 having a tapered portion 21 that widens upward is formed on the protrusions 19.

Next, the lid 2 fitted to the lid fitting portion 22.
3 are provided. The upper surface of the lid 23 is the inner cylinder 1
8 is the same as the upper surface. And the lid 2
On the upper surface of 3, a main display portion 24, which is displayed as a "gate valve", is formed by casting. Further, on the inner surface 25 of the lid 23, a nameplate mounting surface 27 for mounting a nameplate 26.
And the rib 28 are formed orthogonally. A small screw 29 for attaching the nameplate 26 is screwed onto the nameplate attachment surface 27. Further, on the inner surface 25 of the lid 23,
A display body 30 is formed to display the type of valve, diameter, piping system, control status, and other necessary items. The display body 30 includes the name plate 26, but includes a display portion 31 such as a sluice valve integrally formed by casting, and a selection body 32 for specifying the display portion 31. Specifically, the display unit 31 displays the types of valves such as “gate valve” and “soft”, and “75”, “100”, “150”, and “200”.
Calibers such as "250", "300" and "400", and "strike"
It consists of a piping system such as "mud", "delivery", "distribution", "supply", etc. The control status and other necessary items are described on the name plate 26. Further, one screw hole 33 is formed close to each display portion 31, and the type of valve, the bore diameter, the piping system, etc., each of which has a plurality of requirements, are provided in the screw hole 33. It is specified by a machine screw 34 as the selection body 32 to be screwed. For example, in the one shown in FIG. 6, the valve type is a “gate valve” and the bore is “75 mm”.
It is specified that the piping system is “water supply”. The material of the machine screw 34 is made of stainless steel so that it does not rust and maintains the display function for a long time.

A handle 35 formed by bending a wire having a predetermined diameter into a U-shape is attached to the lid 23.
That is, the through holes 36 are formed at both ends of the name plate mounting surface 27, and the handle embedding groove 37 is formed on the upper surface of the name plate mounting surface 27 so that the handle 35 is vertically movable. A nut 38 is attached to the end of the handle 35 to prevent it from coming off. These nuts 38 are
It is provided so as to come into contact with the lower surface of the projection 19 when the position is changed in the circumferential direction. A recess 39 for pulling up the grip 35 is formed in the center of the grip embedding groove 37.

In such a construction, the slab 10 and the frame body 11 are arranged and the box body 12 is mounted on the slab 10 during the laying work. Although the size varies depending on the installation location from the slab 10 to the surface of the earth, the frame 11 having a height corresponding to the size is selected and installed. In some cases,
A plurality of frame bodies 11 may be placed in a stack. Then, the inner cylinder 18 is screwed to the box body 12. At this time, the rotation angle of the inner cylinder 18 is adjusted so that the upper surface of the inner cylinder 18 coincides with the ground surface. That is, the inner cylinder 18 and the box body 1
Since it is connected to 2 by the screw parts 16 and 17, the inner cylinder 1
By turning 8, the height of the inner cylinder 18 moves up and down. The inner cylinder 18 can be rotated by using the grip 35 after attaching the lid 23, as described later. Then, when attaching the lid 23, the nut 3 of the handle 35 is attached.
8 is aligned with the position where the protrusion 19 is not present, and the nut 38 is passed from the top to the bottom. When the handle 35 is released, the handle 35 does not fall into the handle embedding groove 37 and the handle 35 does not protrude from the upper surface of the lid 23.

In the thus installed state,
When it becomes necessary to operate the sluice valve or the like for some reason, as shown in FIG.
9 is used to pull up the handle 35, and the lid 23 is removed while holding the handle 35. At this time, the nut 38 of the handle 35 must be aligned with the protrusion 19, but the handle 3
The nut 38 can be aligned with the protrusion 19 by rotating 5 in the position direction to bring the handle 35 into contact with the edge of the protrusion 19 and then returning it slightly. Then, when the removed lid 23 is turned over, the state of the display body 30 is obvious, and in the one shown in FIG. 6, the type of valve is a sluice valve, the caliber is 75 mm, and the pipeline system is water supply system. Can be easily recognized. Although not particularly shown, other information can be read by the display on the nameplate 26. Therefore, it is possible to know the condition of the pipeline at the site without the need for materials such as construction drawings, and it is possible to immediately perform the necessary work. Therefore, in the event of a disaster in which various facilities are destroyed over a wide area, the functions of the management department are also paralyzed, so conventionally, necessary information could not be obtained at the site, and the recovery would be significantly delayed. Although there is a possibility that the necessary information is displayed on the inner surface 25 of the lid 23 as described above, it is possible to respond very quickly. Of course, even in normal times, it is very useful for organizing and grasping the complicated pipes, and even when the person in charge changes, it greatly contributes to the performance of the work of the new employee.

Further, with the passage of time from the time of installation, the ground at the installation site may change, and the lid 23 may be buried in the surface of the earth or may protrude from the surface of the earth. In this state, as shown in FIG. 5, when the handle 35 is rotated while being held, the handle 35 comes into contact with the edge portion of the projection 19 and the inner cylinder 18 rotates. This makes it easy to adjust the vertical position of the inner cylinder 18 so that the upper surface of the lid 23 and the ground surface coincide with each other. Moreover, since this adjustment can be performed even with a very small size, it is possible to perfectly match with the ground surface.
