The rail 14 is a structure for mounting and rotating the rotary shaft 60 of the lid 20 and has a bar shape with a rail groove in which upper and lower portions are penetrated.

The lid 20 is composed of a ceiling lid 30 and a side wall lid 40 according to the structure of the ceiling side check window 12 and the side wall side check window 13. Although a concrete body can be used, Iron is preferred.

The ceiling side lid 30 is a plate type for opening and closing the ceiling side check window 12. The side wall side lid 40 is formed extending from one side end of the ceiling side lid 30 toward the bottom at right angles, And opens and closes the inspection window 13. The ceiling-side check window (12) has a handle.

In addition, a support base 50 may be constructed in which both side portions in the longitudinal direction are connected to the ceiling cover portion 30 and the side wall cover portion 40, respectively.

The support base 50 is connected to the ceiling lid 30 and the side wall lid 40 on both sides in the longitudinal direction when the ceiling lid 30 and the side wall lid 40 are integrated, Side lid 30 and the side wall-side lid 40 are separated from each other, only one side is connected to the ceiling-side lid 30 and the other side is not connected to the side-wall-side lid 40.

The lid 20 is formed with a rotary shaft 60 at the lower end of the side wall side lid 40.

The rotary shaft 60 is slidably inserted into the rail groove of the rail 14 from the upper portion to the lower portion thereof and rotates in the rail groove to guide opening and closing of the lid 20.

Such a right angle type lid 20 is supported by the angle side of the ceiling side lid portion 30 and is supported by the side wall side lid portion 40, so that there is no dispersion due to the load because of the dispersion effect.

The ceiling side lid 30 and the side wall side lid 40 close the ceiling side check window 12 and the side wall side check window 13 and allow the operator to open the cavity body 10 through the inspection windows 12, (31, 41) having work holes (32, 42) and work hole covers (33, 43) so that the inside can be confirmed.

The lid frames 31 and 41 are each a structure having work holes 32 and 42 as a space for the operator to visually confirm the inside of the cavity 100 from outside the cavity 100, .

The work hole covers 33 and 43 are plate-shaped for opening and closing the work holes 32 and 42, and one side thereof can be hinged to the cover frames 31 and 41, for example. Of course, the work hole covers 33 and 43 are not limited to the hinges but may be slideable.

4, a working plate receiving groove is formed on the upper surface (closed state reference) of the working hole cover 33 of the ceiling cover 30, and the working plate receiving groove is provided with a display panel (34).

One side of the display panel 34 is rotatably engaged and a shock absorber is mounted on both left and right sides for stable opening and closing.

According to this structure, the display panel 34 can be rotated from the work hole cover 33 to display a safety phrase to a driver traveling in a tunnel both when the inspection window is closed and when the inspection window is opened.

That is, the ceiling-side cover portion 30 is composed of the work hole cover 33 and the display panel 34 in duplicate.

The operation of the tunnel junction having a cover for easy maintenance according to the present invention is as follows.

The rotary shaft 60 of the lid 20 composed of the ceiling side lid 30 and the side wall side lid 40 is inserted into the rail groove of the rail 14 of the hollow body 10 and then lowered, Is installed in the main body (10). 2 is a state in which the inspection window 11 of the hollow section 100 is closed through the lid 20. Fig.

The ceiling cover 30 is supported through the angles and is supported by the side wall cover 40 and the support base 50 to close the inspection window 11 without being warped even when the load of the operator is transferred.

The worker can confirm the inside of the hollow body 10 by opening only the work hole covers 33 and 43 without opening the lid 20. That is, the worker can confirm the inside of the hollow body 10 without forcibly opening the lid 20 Since the inside of the body 10 is inspected, the inspection work is very easy.

If it is necessary to repair the cables wired in the cavity 100 as a result of such inspection work, the inspection windows 12 and 13 are opened by opening the lid 20 as shown in Fig. 3 in the state of Fig. When the handle 20 of the lid 20 is held and rotated in the reference clockwise direction, the lid 20 is rotated in response to the guidance of the rotary shaft 60 so that both the ceiling-side check window 12 and the side-wall-side check window 13 are opened .

Therefore, a wider inspection space is secured than before, and the operator can quickly and accurately perform repair work, thereby safely managing various wirings and the like.

When the display panel 34 is applied, the display panel 34 is turned in a state in which the cover 20 is opened, so that the operator can be easily identified even from a long distance, thereby safely protecting the operator.

When the checking operation is completed, the lid 20 is rotated in the counterclockwise direction to close the inspection windows 12 and 13.

On the other hand, the present invention is characterized in that the ceiling cover 30 and the side wall cover 40 are both opened and closed, and only one of the ceiling cover 30 and the side wall cover 40 is opened and closed It is also possible to open both the ceiling-side inspection window 12 and the side-wall-side inspection windows 13 to perform maintenance work using a wide space. However, if work can be performed even in a narrow work space, 12 and 13), it is possible to more easily open and close the lid 20.
