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

The present invention relates to a manhole repair method using a linear manhole housing supporting device and a tubular die.

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.

The guide 300 may be a member having a cross section, And one end of the leg member 400 is rotated at one side of the inner groove of the guide 300 so that one side of the leg member 400 is coupled to one side of the support member 600, By the magnetic force of the magnet 420.

(d) is a step of installing the manhole housing supporting apparatus 10 of the step (c) around the manhole 1 to be repaired, as shown in FIG. That is, step (d) is a step of installing the manhole housing supporting device 10 having the manhole housing 20 coupled thereto around the manhole 1 so that the manhole housing 20 is located in the upper hole of the pipe 60. Also, when the height around the manhole 1 is not satisfactory, the level of the ground is adjusted using the fine adjustment member 410. The manhole housing 20 is installed by using the manhole housing supporting apparatus 10 during the repair work of the manhole 1, so that it is economical to use the additional apparatus for lifting the manhole 1. [ In other words, the manhole housing 20 is installed in the manhole housing supporting device 10 and is fixed to the elevation of the raised ground automatically due to its being fixed, so that a secondary apparatus for lifting the manhole 1 is not required. In addition, since a secondary apparatus is not used when the manhole (1) is lifted, the construction can be simplified so that the construction period for repairing the manhole (1) can be shortened.

(e) is a step of filling the space between the cut surface and the outer diameter surface of the manhole housing 20 with the filler 70, as shown in FIG. (e) is a step of filling the space between the cut surface and the manhole housing 20 by filling the filler 70 in the step (a). As the filler material 70, any material can be used as long as it satisfies the required strength and the role, but a road pavement material is preferably used.

(f) is a step of removing the manhole housing supporting device 10 and installing the manhole cover 30, as shown in Figs. 6 and 7. That is, in the step (f), the manhole housing supporting device 10 and the mold 40 are removed after the manhole housing 20 is removed from the manhole housing supporting device 10, and the manhole cover 20 30). The first expansion member 45 or the second expansion member 47 of the mold 40 is made of a material that does not stick to the filler material 70 and can be easily removed after the completion of the construction.
