Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manhole repairing method using a manhole housing supporting device and a formwork for repairing a manhole,

The present invention relates to a manhole repairing method using a manhole housing supporting apparatus and a form for repairing a manhole, and more particularly, to a manhole housing supporting apparatus having a vise flyer installed on a leg member to secure an upper end of the manhole housing, The present invention relates to a manhole repairing method using a manhole housing supporting device and a mold, which can be installed and demounted quickly when a manhole is repaired.

Generally, a lot of facilities such as a water pipe, a sewer pipe, a power cable, a communication cable, etc. are embedded in the underground of roads and indoors, and these various facilities should be repaired from time to time as needed. Therefore, manholes are installed at regular intervals for the maintenance of various facilities underground.

Typically, roads are overlayed at a period of 4 to 5 years, as roads become aged and uneven due to frequent car traffic and cracks occur in the ground.

However, since the surface of the road is higher than the surface of the existing manhole, the difference in height between the road surface and the manhole occurs when the road overlaying operation is performed. As a cause of the accident, the manhole must be repaired and the maintenance of the manhole must be made to match the surface of the overpassed road.

The manhole repair work for adjusting the height of the manhole conventionally includes a method of using a height adjustment ring, a method of holding the manhole cover support by a spring from below and adjusting the nut from above, or a method of holding a brick or a rock under the manhole cover base, And a method of adjusting the height of the manhole cover by fixing a height adjusting ring made of iron on the top of the manhole cover pedestal without excavating the road surface. However, in the conventional manhole method, The height of the manhole can be adjusted by inserting the height adjustment ring made of iron into the upper part of the manhole cover pedestal without excavating the road surface and adjusting the height of the manhole. The manhole is repaired using the constant height of the height adjustment ring Since the manhole height adjustment made as to, the impression occurs if the manhole is higher or lower than the road surface has the disadvantage that the problem of the flatness of the road slope falls occur.

In order to overcome this problem, a device for supporting a manhole cover pedestal from above has been developed (10-2009-0022508, 10-2009-0098846), but it is complicated to use in the field and there is a problem in stability with respect to the connection with a manhole cover pedestal, 10-2009-0022508 and 10-2009-0098846 have a problem that a certain size of the manhole cover pedestal should be limited to one apparatus.
