Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a manhole pull-

The present invention relates to a manhole pull-up structure and method using a tube pressure bag.

Generally, a lot of facilities such as a water pipe, a sewer pipe, a power cable pipe, and a communication cable pipe are buried in the lower part of the pavement, and such various facilities should be maintained at any time as needed.

Therefore, manholes are installed at regular intervals for the maintenance of various facilities under the road.

Here, FIG. 1 is a sectional view showing a manhole constructed by a general manhole construction method, and FIG. 2 is a sectional view showing an overlay construction on a manhole of FIG.

As shown in these drawings, a conventional manhole has a manhole slab 10 in which a circular hollow 12 is formed so as to communicate with an underground channel, is buried in the ground, and a cylindrical manhole pedestal 20 And a manhole cover 22 made of a metal material is installed on the upper end of the manhole cover 20.

On the outer side of the manhole pedestal 20, a base material and a surface layer material are sequentially packaged to form a road surface layer 24 of the road.

At this time, since the road is repeatedly loaded due to the running of the vehicle after the construction, the ground subsides and the road surface is cracked or broken.

Thus, the overlay layer 16 is formed on the road surface layer 24 so that the top of the manhole pedestal 20 is covered with the overlay layer 16 The manhole portion is recessed from the road surface so that the height of the manhole is adjusted so as to coincide with the overlay layer 16 on the road surface layer 24 before the road surface layer 24 is overlaid. Perform construction work.

Further, when a vehicle or a person passes through the road after the manhole constructed on the road, the brick 14 constituting the manhole breaks due to continuous vibration and load, or is depressed to the inside facing each other, In this case, the manhole repair work is performed to adjust the height of the manhole.

In particular, in the case of a manhole installed on a sloping road, the manhole settlement phenomenon appears more severe, so manhole repair work is more frequently performed on sloped roads.

A description will now be given of a process of performing such manhole repair and lifting work. The main surface of the depressed manhole cover is excavated and removed by using a machine such as a cutter or an excavator.

Then, the height of the upper end of the manhole pedestal is adjusted to be equal to the height of the road surface layer by using a height adjusting device of the height of the upper end of the manhole pedestal.

Then, the filler is filled around the manhole pedestal while the height of the manhole pedestal is adjusted to the height of the road surface layer, and then the filler is filled on the filler material to complete the manhole repair work.

However, in the conventional manhole repair method, since the durability of the filler and the finishing material is relatively low, there is a disadvantage that the manhole repair work must be frequently performed.

In addition, there is a problem in that the curing time of the filler and the finishing material is long, so that traffic control is required for a long period of time. In addition, there is a problem that the vibration equipment for charging and compaction is required and the manhole repair work is troublesome.

Meanwhile, in the conventional manhole lifting work for adjusting the height of the manhole, there are a method of using the height adjusting ring and a method of holding the manhole pedestal 20 by a spring from below and tightening the nut from above, or brick or stone, And a method of adjusting the height of the manhole pedestal 20 by fixing the height adjusting ring made of iron to the top of the manhole pedestal 20 without excavating the road surface.

However, in the repair work of the conventional manhole, a plurality of workers have to work on lifting the manhole cover 22 and the pedestal 10, all of which are heavy, over the road surface layer 24.

The brick 14 accumulated on the manhole slab 10 is completely removed to expose the upper surface of the hollow portion 12 of the manhole slab 10 to the outside and clean the manhole slab 10 And then a standardized height adjustment ring is installed.

Even in this case, since the height of the height adjustment ring is made to be constant, the height of the raised manhole is higher or lower than that of the road surface. Therefore, even if the manhole is repaired, the flatness of the road is lowered. The tightened height adjustment ring and tightening bolt and nut are easily broken by the impact load and vibration of the passing vehicle and the height adjusting ring is moved, which causes cracking or breakage of the road surface layer 24. [

In order to adjust the manhole pedestal 20 by tightening the nut from above, it is necessary to raise the manhole pedestal 20, which is a heavy object, below the spring height in order to place the spring under the manhole pedestal. There is a limited problem that the spring can be used only if the spring thickness is greater than the spring thickness.

In addition, the method of adjusting the height of the manhole by inserting and fixing the height adjusting ring made of iron to the top of the manhole pedestal 20 without the need to excavate the road surface is also installed by using the standardized height adjusting ring, Since the height of the manhole is adjusted by a certain thickness of the ring, the raised manhole is higher or lower than the road surface, and the flatness with the sloped surface of the road is lowered.

On the other hand, when the mortar or other filler material is filled in the empty space, a thin plywood, a plastic plate material or an automobile tire is filled with air when there is an empty space between the bottom surface of the manhole cover and the manhole- It is used as formwork.

However, when a thin plate or automobile tire is used as a form when filling the filler, the uneven portion on the surface of the manhole slab 10 or the manhole cover pedestal 20 is not completely clogged, so that the filler material leaks into the gap The filling material is not densely filled, so that the strength is lowered and the fixing force of the manhole cover 20 is lowered.
