Description

[Detailed Description of the Invention] "Field of Industrial Application" The present invention relates to the provision of a method for relocating and restoring excavated objects related to the preservation of ruins, etc.

``Conventional technology'' When ruins (dwelling ruins, burial mounds, etc.) are found due to housing development or road construction, related parties request preservation from the perspective of preserving cultural assets. There are cases where it is preserved at the excavation site and cases where it is moved and preserved at a different location. If most of the ruins were excavated for housing development or road construction, it would be difficult to preserve them at the excavation site, and those that needed to be preserved would have to be relocated for preservation. When relocating a structure, a thorough investigation and relocation plan must be made, but the conventional method has been to dismantle the structure and restore it at a different location.

``The problem that the invention seeks to solve'' However, with this method, the ruins are not in their original state when buried, and have no value as cultural assets, but merely restore the original shape of the ruins.
Furthermore, when dismantling a building, it takes a lot of time and manpower to investigate (measuring, sketching, photographing, etc.), and it also takes a lot of time and manpower to restore it at the new location. Meanwhile, construction works such as housing land development and road construction stopped during this period, resulting in huge losses. Furthermore, due to the cost of preservation, it has not been possible to preserve it as desired.

"Means for Solving Problems" and "Operation" The present invention was made in view of the above circumstances, and its gist is to spray a solidified chemical solution on the surface of the ground to be relocated and into the ground. After pouring and solidifying, a four-circumference form made of steel plate or PC board is driven in, leaving an upright part of a predetermined height, and the outside of the four-circumference form is excavated to a predetermined point below the bottom edge of the form. A working space is formed, and cushioning material is filled in the upright part of the formwork around the four sides.Meanwhile, a steel plate for the bottom plate is drilled horizontally from the lower end of the formwork from the working space, and a group of guide drill holes is drilled and then press-fitted to cover the bottom. In addition, an iron or PC plate top cover is placed on the top end of the formwork, and the top cover and bottom cover are fastened with bolts across the body to form a block body.
This block body was transported by crane and relocated.
The block was turned upside down, the bottom cover was removed, the exposed solidified soil was removed, concrete was poured, the excavated material receiving base was replaced with concrete, and the block was turned upside down again. If the top cover, formwork, cushioning material, joint clay, etc. are removed and the original shape is restored, the excavation work that requires the most attention can be moved to a suitable work site, so that the original shape can be restored. It is possible to preserve it without giving away any damage, and the excavation work can be done in a short period of time and at low cost.

"Example" This will be explained in detail below based on the drawings.

FIG. 1 shows a vertical cross section of a ruin 2, such as a habitation site, scattered with paving stones 1, .

Therefore, in order to strengthen the solidification of the surface layer, a solidifying chemical solution is sprayed as shown by the arrow in the figure.

As the solidifying chemical liquid, a hydrolytic chemical liquid such as an isocyanate compound is preferable.

FIG. 2 shows a mode in which a strainer pipe 3 is inserted and a chemical solution is injected in order to solidify and strengthen the ground below the surface layer.

Once the ruins 2 to be excavated have been solidified and stabilized as a whole, a four-circumference formwork 4 made of steel plate or PC board is driven in leaving an upright part 4a of a predetermined height as shown in Fig. 3, and the outside is placed a predetermined lower part than the lower end of the formwork 4. The trench 5 is formed by digging up the trench.

The groove 5 becomes a working space for the process described later.

FIG. 4 shows a state in which the upright portion 4a is filled with a cushion material 15 such as urethane foam,
At this time, applying Japanese paper 16 with water to the roofing stones or the soil of the remains of the residence will protect the surface and allow the filling to blend in well.

Figure 5 shows holes 6, . . . being drilled horizontally from the lower end of the formwork 4 using the groove 5 as a working space. The bottom plate is loosened, and the bottom plate is pressed in using the holes 6, . . . as a guide. Make it easier.

At this time, if it is found during drilling that this part is not sufficiently united, it is advisable to insert a strainer pipe 3 as shown in the figure to replenish the chemical solution.

FIG. 6 shows a mode in which a steel plate 7 for the bottom plate is press-fitted with a jack 9 supported by a reaction plate 8 to cover the bottom of the formwork 4 using the perforations 6, . . . as guides.

With this, Ruins 2 is housed in a box with a bottom.

FIG. 7 shows an embodiment in which an iron top lid 10 is placed on the upper end of the formwork 4, and connecting bolts 11 are passed between the top lid and the bottom lid and fastened to form a portable block body.

Figure 8 shows that after the block body is transported to a predetermined location,
This shows how it is unloaded upside down when unloading with a crane, etc.

This is to replace the solidified and stabilized soil on which the ruins 2 are placed with concrete, which will serve as a stable loading base.

Figure 9 shows a state in which the bottom cover has been removed and reinforced concrete 14 has been poured into it with mesh 13 to integrate it, and the excavated material has been replaced on a stable foundation.

Although illustrations are omitted hereafter, after turning the head upside down again to return to the normal position and removing the top cover 10, the cushion material 15 as a covering, Japanese paper 16, and joint clay material 1 are removed.
If the second grade is removed, the original shape will be restored.

Figures 10a and 10b show the embodiment of the present invention applied to the volcanic cone 17, in which figure a shows the chemical liquid being sprayed on the surface layer, and figure b shows the chemical liquid injected into the ground. In this case, since the circumference is usually low as shown in the figure, it is understood that excavating the circumferential groove for press-fitting the bottom plate is omitted.

``Effects of the Invention'' Compared to conventional methods, the method of the present invention allows for preservation without deforming the original form because it is relocated and preserved without dismantling it, and moreover, it is short-term and inexpensive. can.
