The present invention relates to a packaging method for the establishment of a package including the installation of a manhole frame or for the exchange of a package that has already been constructed.

In the conventional pavement method, the pavement layer is usually placed after the mantle frame is installed by installing a fixed foundation on the bare base wall on the unpaved road surface.

However, in this case, the pavement layer protrudes upward from the unpaved road surface of the manhole frame, so that one or both of the pavement layers are damaged or damaged due to the collision between the working machine and the mantle frame. Therefore, after paving the road without paving the mantle frame area, it is post-installed by manual labor or the like.

This has a problem that the workability of the packaging is significantly reduced.

SUMMARY OF THE INVENTION An object of the present invention is to provide a paving method capable of constructably constructing work on an unpaved road surface without bypassing the mantle in the paving of a road including the mantle.

The packaging method of the present invention for achieving the above object is a manhole frame is installed on the manhole base wall at the same time the manhole frame is installed on the fixing base, and the mandrel packing is placed in the space around the manhole frame In a paving method including the installation of a groove frame, a process of installing a support cover on the bare base wall in an unpaved road surface, a process of paving a paved layer on the unpaved road surface to form a paving layer, and a region to be installed in the manhole frame And a step of cutting the pavement layer of the cylindrical shape and simultaneously cutting the pavement layer and the support surface.

Therefore, the pavement method of the present invention can be applied to the unpaved road surface with good workability without bypassing the manhole frame at the time of new pavement or replacement of the pavement already constructed.

Below. EMBODIMENT OF THE INVENTION The packaging method of this invention is demonstrated in detail based on an accompanying drawing.

1 to 4 are cross-sectional views showing the process of the packaging method according to the present invention, Figure 1 is a state after placing the packaging layer on the unpaved road surface, Figure 2 is a state to remove the cutting packaging plate and the support cover, third 4 shows the state after installing the manhole frame, and FIG. 4 shows the state after pouring the pavement layer around the manhole frame.

In FIG. 1, a pavement layer 4 is placed on an unpaved road surface 1 at the same time as a circular iron plate and a cylindrical support cover 3 protruding from the lower surface thereof are installed on a manhole base wall 2 in an unpaved road surface 1. It is constructed in this predetermined configuration.

On the surface of the support cover (3): underlay paper (路 盤 紙: underlay paper): in order to reduce the roadbed friction stress after hardening of concrete to prevent the mortar of concrete from being absorbed by the roadbed in concrete pavement It is a paper laid on the roadbed, and in general, kraft paper, polyethylene film, taboring paper, or the like is used, or other release materials are coated or adhered in advance.

In FIG. 2, the pavement layer 4 around the installation range of the manhole frame 5, i.e., the area to be installed, is formed in a cylindrical shape by a known road cutter (not shown). The cutting packaging material 6 and the indicator cover 3 are removed integrally or sequentially through the anchor bolt and the like while being cut to depth.

As disclosed in the conventional pavement method of cutting the pavement around the manhole frame 15 into a quadrangle, or Japanese Unexamined Patent Application No. 61-25844 or Japanese Unexamined Patent Application No. 61-33938, According to the shearing process in the improved packaging method for cutting the package into a circular shape, the package around the manhole frame may be cut into a cylindrical shape.

In FIG. 3, a fixed foundation 7 is built on the manhole base wall 2 to a predetermined height. That is, a thin coarse material composed of precast concrete and a thin material composed of epoxy resin concrete, which is a kind of thermosetting resin, which is relatively fine-adjustable, for example. A fixed foundation 7 composed of a combination with a fine adjustment material is provided.

The manhole frame 5 is installed on the fixing base 7.

In the fourth degree. The pre-process is completed by pouring the packaging material 8 to the surface height of the packaging layer 4 which is already packaged in the space 10 around the manhole frame 5. In FIG. 4, reference numeral 12 denotes a conventional manhole cover which is covered by the manhole frame 5.

The unpaved road surface may be an unpaved road surface at the time of new paving and a repaved road surface at the time of packaging replacement, and an unpaved road surface after removing the manhole frame.

Next, the effect of this invention is demonstrated in detail.

The greatest effect of the present invention is that it can be efficiently installed on unpaved road surface without bypassing the manhole frame at the time of new paving or repacking of already constructed paving.

In addition, the pavement method of the present invention can be systemized into a l-step by serializing the process up to the circular cutting, demolition work, recovery work, traffic opening.

This system enables a single workbench to be constructed in one process, eliminating the need for temporary restoration of the site during construction, and continuing work without leaving the site.

In addition, the construction of three paving system systems equipped with dedicated tools, machines, and materials, which can be referred to as the factories of the upper manhole maintenance work, can be completed in a short time.

Moreover, according to the packaging method of this invention, low noise of 74 dB (A) or less is achieved.

That is, in the conventional method, since the attention is cut into squares by the cutting process and the concrete brake is used in the crushing process, a loud noise or vibration is generated, but in the pavement method of the present invention, the cutting generates the loudest noise during the process. In the process, the low noise circular cutting cutter cuts the required minimum area and cuts quickly with low noise and low vibration.

In the demolition process, the truck crane pulls out the manhole together with the surrounding asphalt mass, so that noise and vibration are hardly generated.

In addition, a low noise and low vibration circular voltage generator is also used to prevent noise and vibration.

It was confirmed that the construction noise generated at the cutting of the road surface of the pavement method of the present invention was `` 74 m (A) or less on the machine side 7 m four-way energy average. ''

In addition, the packaging method of the present invention is easy to repair.

Conventionally, maintenance of manholes due to road construction has caused various problems in pavement construction, cutting pavement construction, pavement replacement construction, and pavement construction.

For example, in the paving new construction, the hole in which the manhole is inserted remains convex, so that workability of a vehicle or heavy machinery, etc. is remarkably degraded, or an adjustment part is damaged, thereby requiring repair or shifting of the shift. There was.

However, the paving method of the present invention does not require temporary interruption of construction or construction according to the manhole construction required by the conventional construction method, and enables construction by checking the manhole position with a detector after the entire paving is completed.

In addition, since the lid height adjustment or replacement work is carried out after the paving work, no step is generated, thereby ensuring the safety of traffic.

In addition, since the construction is performed in accordance with the inclination of the longitudinal and horizontal cross sections of the road pavement, the finish can realize flatness with the road surface.

And since the paving work can be carried out without worrying about the manhole, sufficient paving voltage is also possible, thereby satisfying the density of the paving.

As described above, according to the paving method of the present invention, the paving layer is pre-installed, the manhole frame is cut out, the entire manhole frame is lifted, and then the fixed foundation is constructed and the paving material is poured into the space. Even if there is a manhole frame on the pavement surface, there is no need for careful construction, which greatly improves the workability, and because no step is formed, the noise of construction is reduced and the environment for local residents, pedestrians, traffic vehicles, and construction workers in the construction zone And safety can be secured and low pollution can be achieved.

In addition, since the fixed foundation of the present invention is a fixed foundation composed of a dual structure, that is, a combination of a thick crude adjustment material and a thin non-adjustment material that is relatively fine-adjustable, Compared with the point support, the height adjustment is more precise, the stability is achieved, and the entire parts are supported by the surface support, so that there is an effect of maintaining high flatness and greatly improving durability.
