Description

Repair device around the iron lid of manhole

The present invention relates to a repair apparatus around the reinforcing of a manhole, and more particularly, by ensuring that the upper end of the rebar of the manhole to be repaired exactly matches the top of the existing road surface, not only can the quality of the repair work around the rebar be improved, but also concrete and It relates to a repair device around the iron bars of a manhole that allows the ease of pouring asphalt concrete to increase the efficiency of the repair work around the iron bars.

Various facilities such as water pipes, sewage pipes, gas pipes, power cables and communication cables are buried under the road surface.

At this time, since the underground facilities under the road surface frequently require maintenance, a manhole for the underground access of the facility manager is provided on the road surface.

On the other hand, the manhole is a rim-type iron rod that is fixedly installed at the entrance of the slab leading to the basement; and a cover seated on the iron rod to block the opening of the entrance of the slab.

Therefore, underground access can be made by opening the cover, and underground access can be restricted by closing the cover.

Here, the cheolgae is initially installed so that its upper end coincides with the upper end of the road surface.

And the top of the cover coincides with the top of the iron rod while it is seated on the iron rod.

Therefore, even when a vehicle is driven and a pedestrian walks in the upper part of the manhole, interference caused by the retractor and the cover is prevented.

However, the upper end of the manhole is gradually lowered compared to the upper end of the surrounding road surface due to pressure applied during vehicle driving, partial depression due to aging of the road surface, and additional pavement of the road surface. This causes interference with vehicle driving and pedestrian walking, which may lead to accidents.

For this reason, repair work around the iron rod is being carried out targeting the manhole where the iron rod has fallen.

During the repair work around the iron rod of the manhole, the height of the iron rod that was lowered compared to the beginning is raised so that the upper end coincides with the top of the surrounding road surface, and asphalt concrete and concrete are re-cast around the iron rod where the raised iron rod is made.

In the course of repair work around the manhole rebar, if the reel is raised manually, a large number of workers are required, and the workers are significantly fatigued. There was a problem with this degradation.

And, in the course of repair work around the manhole removal, if the formwork is separately installed to match the inner surface of the slab for concrete pouring, considerable work time is required, so there is a problem in that work efficiency is lowered.

For the above reasons, in this field, not only can the quality of the repair work around the rebar be improved by making the top of the rebar of the manhole to be repaired exactly matches the top of the existing road surface, but it also makes it easy to pour concrete and asphalt concrete around the rebar, so the efficiency of the repair work around the rebar Although attempts are being made to develop a repair device around the removal of manholes that can increase the

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

As shown in FIG. 1, the repair device (A) around the manhole according to the present invention includes a support unit (10); Rotating unit 20; and a close contact portion 30 .

The support portion 10 of the present invention is mounted on the inlet of the slab 100 of the manhole, and is fixed by attaching the iron rod 200 with magnetic force.

Since the iron rod 200 is fixed by the support part 10, the inconvenience of manually lifting and fixing the iron rod 200 is eliminated.

At this time, the support portion 10 is arranged so that the inner angle between one and the other adjacent to it is constant, each of the front end of the support member 11 that continues to the outside of the slab 100; and a movable member 12 slidably coupled to each of the support members 11 in the longitudinal direction; and an electromagnet 13 disposed on the bottom surface of each of the movable members 12 to exert a magnetic force according to the application of power.

Accordingly, as each of the moving members 12 coupled to the support member 11 slides around the support part 10 , each of the electromagnets 13 may be inserted into the iron rod 200 , and coupled to the support member 11 . As each of the movable members 12 slides out of the support 10 , each of the electromagnets 13 may be in close contact with the inner peripheral surface of the iron rod 200 .

Here, the support member 11 includes a switch 11a for controlling the operation of the electromagnet 13, so that the operation of the electromagnet 13 is controlled by the operation of the switch 11a.

And, since the moving member 12 includes a handle 12a providing a gripping portion, sliding of the movable member 12 may be facilitated by pushing or pulling while gripping the handle 12a.

In addition, the movable member 12 includes a locking member 12b for limiting sliding, thereby preventing the movable member 12 from being unintentionally separated from the supporting member 11 by locking the locking member 12b.

At this time, the locking member 12b may have any structure and method in general as long as it can limit the sliding of the moving member 12 , and an example of the locking member 12b is a bolt that penetrates through the upper surface of the moving member 12 and is fastened. can

The rotating part 20 of the present invention passes through the center of the support part 10 in a vertical direction and extends from the top of the road to the inside of the slab 100, and rotates clockwise and counterclockwise around the center of the support part 10 as an axis. do.

Therefore, the contact part 30 provided at the lower end of the rotating part 20 is positioned inside the slab 100 , and the diameter of the contact part 30 is varied by rotation of the rotating part 20 .

At this time, the rotating part 20, but passing through the center of the support part 10 in the vertical direction, the gear teeth (21a) along the periphery of the lower end of the rotating shaft 21 formed; and a handle 22 coupled to the upper end of the rotation shaft 21 to provide a gripping part, whereby the gear teeth 21a of the rotation shaft 21 are formed in the coupling member 31 of the close contact part 30 to be described below. The rotation of the coupling member 31 is made by the rotation of the rotation shaft 21 according to the meshing with the gear teeth 31a, and the rotation of the rotation shaft 21 is smooth as the handle 22 is gripped and turned.

Here, the rotation shaft 21 can be inclined in various directions on the support part 10 by forming a ball-shaped coupling portion with the support part 10, so that the handle 22 is manipulated by tilting the rotation shaft 21 in a situation where the road surface is inclined, etc. This can be easy.

The contact part 30 of the present invention is coupled to the lower end of the rotating unit 20, and as the diameter increases by the rotation of the rotating unit 20, it is in close contact with the inner surface of the slab 100 under the iron rod 200.

Therefore, by pouring the asphalt concrete 400 and the concrete 300 to the outside of the adhesion portion 30 in close contact with the inner surface of the slab 100, the asphalt concrete 400 and concrete 300 pouring operation can be easy.

At this time, the contact part 30, the rotating part 20, along the periphery of the inner surface coupled to the lower end of the gear tooth (31a) is formed a coupling member 31; Doedoe hinge-coupled to the outer surface of the coupling member 31, the coupling member 31, the coupling member 31 disposed radially around the outer surface of the connecting member 32; and a contact member 33 coupled to the front end of each of the connecting members 32, and having a plate shape of a certain curvature, whereby the connecting member 32 is a hinge shaft by the rotation of the coupling member 31 (not shown) The diameter of the contact member 33 increases or decreases as it is folded or unfolded by rotating around it.

Here, the contact member 33 is disposed so that one longitudinal end overlaps the other longitudinal end adjacent thereto, so that when it has a maximum diameter, any one longitudinal end and the other longitudinal end adjacent thereto are The separation between the contact members 33 can be prevented according to successive or overlapping.

And the contact member 33, the upper end of which is located at an upper portion compared to the lower end of the iron rod 200 fixed to the support unit 10, and the lower end of the contact member 33 is located lower than the upper end of the slab 100. It may be in close contact between the lower end of the cheolgae 200 and the upper end of the slab 100 .

On the other hand, the adhesion part 30 can be easily inserted into the slab 100 inlet when the diameter of the contact member 33 is reduced and is less than the inner diameter of the slab 100 inlet, and the slab 100 is inserted inside the inlet. As the diameter of the contact member 33 expands in the state, it can be in close contact with the inner surface of the slab 100 .

And in the close contact part 30, the coupling member 31 is rotatably disposed in the support part 10, more specifically, a separate fixing member 34 connected from the support member 11, thereby preventing separation of the coupling member 31. .

At this time, an opening 34a for penetration of the connecting member 32 is formed on the outer surface of the fixing member 34 , and the opening 34a is formed in the form of a long hole extending in the horizontal direction, thereby connecting in the opening 34a. Rotation of the member 32 is effected.

When described in detail with respect to the repair around the cheolgae 200 using the repair apparatus (A) around the cheolgae of the manhole according to the present invention.

First, the asphalt concrete 400 and the concrete 300 around the iron rod 200 of the manhole to be repaired are removed.

At this time, the concrete 300 is removed to the lower part of the iron rod 200 , so that the previously installed iron rod 200 can be separated.

Next, the iron rod 200 is fixed to the entrance of the slab 100 from which the asphalt concrete 400 and the concrete 300 are removed, as shown in FIG. 2 .

In the present invention, the support member 11 of the support portion 10 has a bar leading to the outside of the slab 100. As the front end of the support member 11 is caught on the road surface around the slab 100, the support portion ( 10) is mounted at the entrance of the slab 100 of the manhole.

And in the present invention, the moving member 12 of the support 10 includes an electromagnet 13, and since the iron rod 200 is attached by the magnetic force exerted by the electromagnet 13, thereby fixing the iron rod 200 this is done

However, depending on the distance between the electromagnets 13 facing each other, it may be difficult to insert the electromagnet 13 into the iron rod 200 and contact the iron rod 200 with the electromagnet 13 .

However, since the moving member 12 of the present invention slides in the longitudinal direction on each of the supporting members 11 as shown in FIG. 3 , the position of the electromagnet 13 is adjusted by the sliding of the moving member 12 . Accordingly, the insertion of the electromagnet 13 into the iron rod 200 and the contact between the iron rod 200 and the electromagnet 13 may be easy.

That is, as the moving member 12 slides toward the center of the support 10, the electromagnets 13 facing each other are closed, so that the electromagnet 13 can be smoothly inserted into the iron rod 200, and each moving member ( As the 12) slides toward the outside of the support part 10 , the gap between the electromagnets 13 facing each other is widened, so that each electromagnet 13 can be in close contact with the inner circumferential surface of the iron rod 200 .

Here, the moving member 12 may include a handle 12a, and by holding the handle 12a, sliding of the moving member 12 may be smooth.

In addition, the movable member 12 may include a locking member 12b, and by locking the locking member 12b, unintentional sliding of the movable member 12 may be prevented.

On the other hand, when the iron 200 is fixed by the support 10, the bottom surface of the movable member 12 is in contact with the top of the road surface around the manhole, and the top of the iron 200 is in contact with the bottom of the movable member 12. As it is attached and fixed in a state of being fixed, the top of the iron rod 200 naturally coincides with the top of the existing road surface exactly.

Therefore, the quality of the repair work around the iron rod 200 can be improved by fixing the upper end of the iron rod 200 in a state in which it exactly matches the top of the existing road surface.

Next, the contact portion 30 is in close contact with the inner surface of the slab 100 .

The contact member 33 of the contact member 30 of the present invention increases or decreases in diameter as the connecting member 32 is folded or unfolded by the rotation of the coupling member 31 as shown in FIGS. 5 and 6 . As a result, the diameter is expanded by the expansion of the connecting member 32 by the rotation of the coupling member 31 in a state inserted inside the inlet of the slab 100, so that it is in close contact with the inner surface of the slab 100.

And the contact member 33, the upper end is located at an upper portion compared to the lower end of the iron rod 200 fixed to the support portion 10, the lower end of the bar is located lower than the upper end of the slab 100, the contact member 33 ) may be in close contact between the lower end of the iron rod 200 and the upper end of the slab 100 .

When the diameter of the contact member 33 is expanded in the close contact process of the contact part 30 as described above, if the contact members 33 are spaced apart, the concrete 300 in the kneaded state through the spaced portion in the subsequent concrete 300 pouring process. It may be difficult to pour the concrete 300 because it may leak.

However, in the present invention, the contact member 33 is disposed so that one longitudinal end overlaps the other longitudinal end adjacent thereto, and at the maximum diameter, any one longitudinal end and the other adjacent thereto Since the distance between the contact members 33 can be prevented as one end of the longitudinal direction is continuously connected or overlapped, the concrete 300 can be poured smoothly.

In addition, the rotation of the coupling member 31 involved in the diameter expansion and contraction of the contact member 33 in the close contact process of the close contact 30 may be cumbersome.

However, in the present invention, since the rotating part 20 is provided, the rotation of the coupling member 31 can be made simply by the rotating part 20 .

That is, the rotating part 20 of the present invention, but passing through the center of the support part 10 in the vertical direction, along the periphery of the lower end, the gear teeth (21a) are formed along the rotation shaft 21; and a handle 22 coupled to the upper end of the rotation shaft 21 to provide a gripping part; Since the coupling member 31 is simply rotated by the rotation of the rotating shaft 21 as it meshes with the gear teeth 31a formed on the coupling member 31 of the close contact part 30, the coupling member 31 of the close contact part 30 rotates. It can reduce the hassle of following.

Next, the concrete 300 is poured.

In the present invention, the contact member 33 serves as a formwork by being in close contact between the lower end of the iron rod 200 and the upper end of the slab 100, and as shown in FIG. 7, the contact member 33 outside the concrete 300 By putting the concrete 300 around the iron rod 200 can be made simply.

Next, the asphalt concrete 400 is poured over the new concrete 300 pouring site.

In the present invention, the iron rod 200 is located on the upper portion of the contact member 33, and the asphalt concrete 400 is put outside the contact member 33, more specifically, the iron rod 200 located on the upper portion of the contact member 33. By doing so, the asphalt concrete 400 around the iron rod 200 can be poured simply.

At this time, of course, the upper end of the asphalt concrete 400 to be newly poured coincides with the upper end of the existing road surface.

On the other hand, after the concrete 300 and asphalt concrete 400 is poured, the repair device (A) around the manhole according to the present invention is removed from the slab 100 entrance.

At this time, the contact member 33 of the contact part 30 can be simply discharged to the outside of the slab 100 inlet by reducing the diameter by the rotation of the rotating part 20 .

And the electromagnet 13 of the support part 10 can be simply discharged to the outside of the iron rod 200 by releasing the attachment to the iron rod 200 as each of the moving members 12 slides toward the center of the support part 10 .

Here, the electromagnet 13, whose attachment to the iron rod 200 is released, is of course blocked from exerting its magnetic force as the switch 11a is previously switched to the off state.

Since the present invention as described above is not limited to the above-described embodiments, it can be changed within the scope that does not depart from the gist of the present invention as claimed in the claims, and such changes are the present invention defined by the following claims. fall within the protection scope of the invention.
