[0001] The present invention relates to an electric communication manhole,

.

[TECHNICAL FIELD OF THE INVENTION AND RELATED ART OF THE SAME]

The present invention relates to a telecommunication manhole capable of adjusting the vertical position of the lid.

The manhole for telecommunication is mainly buried in the road, and in some cases, it is buried in the roads of India and bicycles. In the present invention, the vertical position of the lid in the manhole buried in the road for exclusive use of automobiles except for the highway is 20mm It is about manholes that can be raised.

Asphalt roads have problems such as grooves piercing or cracking in several places on the asphalt surface as time passes, and gravel is exposed to the entire top surface of the asphalt. Therefore, new asphalt is overlaid on the existing asphalt surface at regular intervals Is being carried out.

However, if a new asphalt surface overlaid on the existing asphalt surface is formed as described above, a gap G of at least 20 mm or more perpendicular to the height of the asphalt surface and the manhole cover should be formed as shown in FIG. 9, When the asphalt overlay is used, the above-mentioned gap (G) increases from a minimum of 20 mm to a maximum of 50 to 60 mm.

Therefore, if the wheel passes over the manhole when the vehicle travels due to the occurrence of the gap (G) described above, a large impact is transmitted to the vehicle, which increases the likelihood of occurrence of a fault in the vehicle. There is a possibility that large and small accidents are likely to occur. The impact generated when the vehicle travels over the manhole is very bad for the driver and the passenger's spine and the cervical vertebrae, resulting in injury to the spine and the cervical vertebrae.

Therefore, it is natural that the above problem and the risk become more serious because the gap (G) between the upper surface of the asphalt and the manhole cover becomes larger as the number of times of covering the asphalt is more than twice as above. There is a case that the manhole cover which is continuously impacted is broken.

On the other hand, Patent Registration No. 10-1377009 relates to a manhole cover which can be adjusted in height and inclination, and is intended to solve the problem that the position of the lid of the manhole is lowered by covering the asphalt as in the present invention, And a wedge which is inserted between the lid support and the outer surface of the insertion member and is tightened by a force in the horizontal direction while the load in the vertical direction is divided vertically and horizontally However, the structure and operation of the present invention are different from those of the present invention, and the durability, safety, and stability of the components are greatly deteriorated in comparison with the present invention.

The following Publication No. 1998-0009836 is an initial type manhole made of a body and a lid as a telecommunication manhole, and is completely different from the constitution of the present invention.

Next, the utility model registration No. 20-0127017 is a telecommunication manhole, in which a reinforcing frame is inserted into the upper edge of the body, which is quite different from the construction of the present invention.

In the following, Publication No. 2001-0016306 relates to a method of constructing a prefabricated manhole, which is quite different from the present invention in all the components to be assembled, the construction method, and the operation.

Next, the utility model registration No. 20-0436633 relates to a prefabricated manhole apparatus, and its operation and effect are completely different from those of the present invention.
