DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for overlaying a pavement including a manhole frame.

[0002]

BACKGROUND OF THE INVENTION Ri of many in the pavement surface cracks and damage,
The pavement thickness becomes insufficient due to vehicle traffic, and
Frame is protruding from the pavement surface and there is a step around it
As a result, the vibration and noise caused by the traffic
As it expands, safe and smooth traffic for vehicles and pedestrians is hindered.
It may be harmed and cause serious traffic accidents.
Therefore, in such a case, the manhole frame is
New table of required thickness on pavement surface as well as raised
A layer, or overlay, is applied, which
It will be repaired and the step around the manhole frame will be eliminated
It is planned. However, the conventional overlay method
Now, when constructing the overlay,
On top of manhole frame, height adjusted for directional gradient
The overlay surface so that it is flush with
Accurate alignment is difficult due to construction technology,
Manhole frame that easily makes a difference and protrudes from the pavement surface
Is an obstacle to smooth surface construction by surface pavement machines.
If, collision from further high sailing Lumpur frame pavement surface after adjusting
Out of the way, and there will be a step around it.
At the time of release, a new
It is necessary to reduce the level difference by applying
And so on.

[0003]

The problem to be solved by the present invention is as follows.
Overlay construction on pavement surface hindered by manhole frame
It can be done very easily with good workability without
In both cases, the upper surface of the manhole frame and the
An object of the present invention is to provide an overlay method capable of easily aligning a burley surface .

[0004]

According to the overlay method of the present invention, in a method of overlaying a pavement including a manhole frame, (a) the manhole frame lid surface is covered with a release material and the pavement surface includes the release material surface. (B) the pavement around the manhole frame is cut into a cylindrical shape from the overlay and the cut pavement plate and the manhole frame are removed; (c) the manhole frame is placed on the manhole base wall. When the installation foundation is constructed, the manhole frame overlays the upper surface of the installation foundation.
(A) a step of setting the surface to the height of the surface;
It consists of a process of casting to the height .

[0005]

In the step (a), the overlay is applied to the pavement surface without bypassing the manhole frame, and the manhole frame is covered with the overlay together with the pavement surface. The release material is used later to cover the manhole frame lid surface or pavement.
It is used for facilitating the peeling of the overlay from the surface , and may be, for example, various agents such as a peeling agent or various sheets such as roadbed paper.

Next, in the steps (b) to (d), a conventional pavement method for cutting the pavement around the manhole frame into a square, or a method disclosed in JP-B-61-25844 and JP-B-61-1984.
As disclosed in JP-A-33938, according to an improved pavement method for cutting pavement around a manhole frame into a circular shape, cylindrical cutting of pavement around a manhole frame, removal of a cut pavement plate and a manhole frame, removal of a manhole base, and the like. Construction of the foundation for installing the manhole frame on the wall, installation of the manhole frame on the installation foundation, and placement of the pavement material into the cavity around the manhole frame are sequentially performed. In step (c),
The ruler frame fits the height of the surface of the overlay
It will be installed at the same time, this is the height adjusted
An overlay is applied according to the height of the top of the manhole frame.
The procedure is the reverse of the conventional technique. Used for this
As the manhole frame, a previously removed manhole frame can be used, but preferably another manhole frame which has been pre-processed so that it can be used immediately is used.

[0007] When cutting pavement around the manhole frame, there is no particular limitation on the cutting means. In the case of cylindrical cutting, for example, a road surface circular cutting machine having a cylindrical bit as disclosed in Japanese Patent Publication No. 61-52283 can be suitably used. The position of the manhole frame cover inside may be confirmed using a known detecting means such as a detector . The cutting pavement around the manhole frame may be removed by crushing using a breaker. However, from the viewpoint of improving workability and preventing noise and vibration, the manhole frame is disclosed as disclosed in JP-B-61-33938. It is preferable to remove it while adhering to the surface. In order to remove the cut pavement plate and the manhole frame integrally, as disclosed in, for example, Japanese Utility Model Laid-Open No. 59-156942 and Japanese Utility Model Laid-Open No. 59-193679,
A manhole frame pulling machine or manhole frame peeling machine or the like in which a wedge or an arm which expands and contracts radially from the inside of the manhole frame is inserted between the manhole frame and the manhole base wall can be used as required.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional view of a pavement for explaining an overlay method according to an embodiment of the present invention over time, (a) after overlaying, (b) after cutting pavement plate and manhole frame are removed. (C) shows each state after the manhole frame is installed, and (d) shows each state after the pavement material is placed around the manhole frame.

[0009] As shown in FIG. 1 (a), as a pretreatment,
On the surface of the cover 2 of the manhole frame 1, it is almost the same diameter or
Is slightly larger circular release material 3 consisting of the subgrade paper is stuck from Re, then tuck the release material 3 surface pavement 4 surface also overlay 5 of required thickness, including without bypassing the manhole frame 1 coat ( (Not shown). Subsequently, as shown in FIG. 1B, the pavement 4 around the manhole frame 1 is cut into a cylindrical shape from the overlay 5 to a depth of the upper surface of the manhole base wall 6 by a known road surface cutting machine (not shown). Then, the overlay 5 on the lid 2 of the manhole frame 1 is peeled off the lid 2 by the peeling action of the release material 3.
And the lid 2 is removed from the manhole frame 1
Pavement plate 7 and manhole frame 1 cut from the opening of
Are removed all at once by a known manhole frame peeling machine 8. Further , as shown in FIG. 1 (c), an installation base 9 of the manhole frame 1 made of a combination of a thick coarse adjustment material and a thin fine adjustment material is constructed on the manhole base wall 6 at a required height, and the installation base is also installed. manhole frame 1 is that on the 9
The upper surface is set according to the height of the overlay 5 surface ,
Finally, as shown in FIG. 1 (d), a pavement material 10 is poured into the cavity around the manhole frame 1 to the height of the surface of the overlay 5, and the entire process is completed.

[0010]

Since the overlay method according to the present invention is configured as described above, the overlay method is applied to the pavement surface.
Workability is extremely easy without the work being hindered by the manhole frame
And the construction of the overlay
To easily align the top of the manhole frame with the overlay surface
Can be made .
