Description

[0001]
BACKGROUND OF THE INVENTION
According to the present invention, a pipe is connected to an oil storage tank buried underground, a box that accommodates a rising portion of the pipe is provided, an opening is opened in a lid attached to an upper end of the box, and the opening is provided. It relates to a manhole for a filling station.
[0002]
[Prior art]
A plurality of oil storage tanks are buried under the gas station, and fuel oils such as regular gasoline, high-octane gasoline, light oil, and kerosene are placed in each oil storage tank. Each oil storage tank is connected with pipes such as an oil supply pipe, an oil supply pipe, a metering pipe, and an air vent pipe, and these are arranged in a manhole. Then, oil is supplied to the oil storage tank by looking at a liquid level gauge attached to the measuring pipe. At this time, if you open the manhole cover and look at the oil level of another oil storage tank, the oil may overflow. In addition, in daily oil level management, if the manhole cover is mistakenly opened and the oil level is measured, the oil level management will be confused. It may become impossible to operate.
[0003]
[Problems to be solved by the invention]
Therefore, the present invention is to provide a manhole for a gas station where the manhole cover is not opened and a mistake is not caused.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a pipe connected to an oil storage tank buried underground, provided with a box for accommodating a rising portion of the pipe, and opened to a lid attached to the upper end of the box. is opened, the manhole fueling Shoyo for lidding the opening, said box, a cylindrical box body enclosing the rising portion of the pipes, is composed of the frame provided at the upper end of the box body, the frame A lid is attached to the body with bolts, a recess is formed in the lid, and a nameplate on which the tank number, oil type, and capacity are written is attached to this recess with a screw, and in the center of the lid A handle for lifting the lid is provided, a notch for inserting a bar is formed around the lid, and the lid is connected to the lid with a chain to ensure that the lid is that of a manhole lid Need it It is an.
[0005]
According to the present invention, a pipe is connected to an oil storage tank buried underground, a box that accommodates a rising portion of the pipe is provided, an opening is opened in the lid attached to the upper end of the box, and the opening Since the nameplate is attached to the lid of the manhole for the gas station where the lid is applied, the contents of the oil storage tank can be confirmed before opening the lid of the manhole. As a result, there is no mistake in opening the manhole cover and no erroneous weighing occurs.
[0006]
And since the tank number, the oil type, and the capacity are written on the nameplate, all the contents of the oil storage tank can be known.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, an oil tank 2, an oil pipe 3, a metering pipe 4, an air vent pipe 5 and the like are connected to an underground tank 1 embedded in a gas station. Located in the manhole 6. The oil supply pipe 2 is connected to a metering machine (not shown) via a horizontal oil supply pipe 7, the oil supply pipe 3 is connected to an oil supply port (not shown) via a horizontal oil supply pipe 8, and a liquid level gauge is connected to the metering pipe 4. 9 is attached, and the air vent pipe 5 communicates with the atmosphere via a horizontal air vent pipe 10.
[0008]
The box 11 of the manhole 6 includes a cylindrical box main body 12 that surrounds the rising portion of each pipe, and a frame body 13 provided at the upper end of the box main body 12. It is attached with. An opening 15 is opened at the position of the lid 14 facing the measuring tube 4 provided in the manhole 6, and the opening 15 is covered with a lid 16.
[0009]
A concave portion 17 is formed in the lid 16, and a name plate 18 is attached to the concave portion 17 with a screw 19. A handle 20 for lifting the lid 16 is provided at the center of the lid 16, and a bar insertion notch 21 is formed around the lid 16. Furthermore, the lid 16 is connected to the lid body 14 by a chain 22 to ensure that the lid 16 is that of the lid body 14 of the manhole 6. As shown in FIG. 3, the nameplate 18 is provided with a tank number description column 18a, an oil type description column 18b, and a tank capacity description column 18c.
[0010]
In order to measure the amount of oil in the oil storage tank 1 when replenishing the oil to the oil storage tank 1 and in daily oil amount management, the tank number, oil type, and tank capacity should be set with the nameplate 18 before the lid 16 of the manhole 6 is opened. As a result, it is confirmed that the oil storage tank is correct, and thereafter, a bar or the like is inserted into the notch 21 to remove the lid 16 and the liquid level gauge 9 attached to the measuring tube 4 is observed.
[0011]
In this way, since the contents of the oil storage tank 1 can be confirmed with the nameplate 18, the lid 16 of the manhole 6 can be prevented from being mistakenly opened, the oil level of the desired oil storage tank can be accurately known, and the oil overflows when refilling. Or confusion in daily oil volume management.
[0012]
When the oil type in the oil storage tank 1 is changed, the name plate 18 may be removed and a new name plate may be attached with screws.
[0013]
【The invention's effect】
As described above, according to the present invention, a pipe is connected to an oil storage tank buried underground, a box for accommodating a rising portion of the pipe is provided, and an opening is opened in a lid attached to the upper end of the box. In the manhole for a gas station that covers the opening, the nameplate is attached to the lid, so that the contents of the oil storage tank can be known before the manhole is opened. As a result, there is no mistake in opening the manhole cover and no erroneous weighing occurs.
