Manhole cover to prevent loss in case of manhole backflow and manhole operation management system using the same}

The present invention relates to a manhole cover for preventing loss in case of backflow of a manhole and a manhole operation management system using the same, and more specifically, by using protrusions and grooves to cover the manhole cover and fasten in a structure that is invisible from the top, so that even if backflow occurs inside the manhole, there is no fear of loss because the manhole cover does not open upward, it is possible to prevent the occurrence of accidents such as pedestrians or workers in case of flooding, and a manhole to prevent loss in case of manhole backflow to systematically manage the history management of the manhole cover. It relates to a lid and a manhole operation management system using the same.

During the summer rainy season or floods caused by typhoons, manhole backflow due to a concentrated lake often occurs. This is because the manhole cover is installed in a structure that can be opened upward. To prevent this, the manhole cover needs to be changed to a structure that does not open upwards.

As a conventional technology related to this, Republic of Korea Patent Application Application No. 10-2013-0005414 (2013.01.17) "Break away for prevention of Manhole cover" is compatible with the existing manhole cover and can be replaced with the existing manhole cover support, and the breakaway prevention device is bitten on the inner periphery of the manhole cover support, so the manhole cover is caused by reverse flow of water and sewage. It is formed as a locking device that prevents the lid from being opened and separated, and the upper fixing member of the separation prevention device can be easily rotated by the rotation member to dismantle the separation prevention device, which is the locking device, to arbitrarily release the manhole cover. A backflow induction device is formed in the center of the manhole cover. When the upper and lower flows back, the disk of the backflow induction device is opened upward to discharge the upper and lower sewage to the outside through the through hole, thereby preventing the manhole cover from being separated by the upper and lower backflow. there is

In addition, the Republic of Korea Patent Application Application No. 10-2006-0116346 (November 21, 2006) "a manhole cover and manhole frame" is intended to prevent the manhole cover from being separated or run away even if sewage or rainwater flows backward, and at the same time, to prevent damage or deformation of the manhole frame or cover, including the sewage pipe or rainwater pipe or manhole.

In addition, Republic of Korea Patent Application Application No. 10-2005-0100151 (2005.10.24) "The Prevention Equipment Of An Electric Shock From The Manhole Cover" is installed on the lower part of the manhole cover and on the inner upper part of the support around the lid to make contact with each other, and one or three kinds of steel plates are installed around the upper inner side of the support around the manhole cover. It is a device that provides the effect of preventing electric shock accidents by grounding more than vertical grounding and lowering the potential of leakage current to the ground.

In addition, Republic of Korea Patent Application Application No. 10-2004-0067865 (August 27, 2004) "A manhole cover having prevention structure of flowing backward of stink" is a manhole cover having a plurality of flowing water holes through which it is exposed to the outside on the road and supported by a lid frame. A manhole cover having an odor backflow prevention structure having a backflow prevention plate for sealing the outflow hole of the water pipe by its own weight.

However, these conventional technologies not only lack preparation for heavy rain or flooding, but also have a problem in that the fastening structure is complicated, and the history management of the manhole cover is not properly managed, resulting in casualties such as passers-by and workers during flooding. There is a limit that cannot be prevented.
