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 (remains of dwellings, burial mounds, etc.) are uncovered due to housing development or road construction, related parties request preservation from the perspective of preserving cultural assets, but conventional preservation of ruins, etc. There are cases where it is preserved at the excavation site and cases where it is moved and preserved at a different location. In most cases, when excavated as part of housing development or road construction, it is difficult to preserve the remains at the excavation site, and the ruins that need to be preserved must be relocated for preservation. When relocating, a thorough investigation and relocation plan must be made, but the conventional method has been to dismantle the structure and restore it at another 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. In addition, when dismantling the building, it takes a lot of time and manpower to investigate (examining the cell, sketches, photographs, etc.), and it also takes a lot of time and manpower to restore it using relocated lights. On the other hand, during this period, construction work such as residential land development and road construction will be stopped.・Sara 60・Save') I have not been able to save as much as I would like due to the expense 9 problem.

[Means for solving the problems], "Operation" The present invention was made in view of the above circumstances, and its gist is that the solidified chemical solution is applied to the surface of the ground to be relocated and to the ground. Spray and inject! Aiming to reduce the noise, then steel plate or PC
A four-circumference formwork of the board is driven leaving a standing part of a predetermined height, and the outside of the four-circle formwork is dug up to a predetermined point below the bottom edge of the formwork to form a work space, and a cushioning material is placed inside the four-circumference formwork's standing part. On the other hand, 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 are drilled and then press-fitted to cover the bottom, and a steel or PC board top cover is placed on the upper end of the formwork. Then, the top and bottom covers are fastened with bolts across the body to form a block body, this brick body is transported and relocated using a crane, turned upside down, the bottom cover is removed, and excavated by pouring concrete. This is suitable for excavation work that requires the most care, as the block body is turned upside down again and the top cover, formwork, cushioning material, joint clay, etc. are removed to restore the original shape. By making it possible to move the excavation work to a suitable work site, it is possible to preserve the original form without causing any deformation, and the excavation work can be carried out in a short period of time and at low cost.

, "Example" .

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

Figure 1 shows the fukiishi 1 to be excavated. The present invention is intended to cut out a longitudinal section of ruins 2, such as scattered habitation ruins, etc., into a rectangular shape at a predetermined depth and relocate them. Therefore, in order to strengthen the solidification of the surface layer, a solidification 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.

The ruins 2 to be excavated have reached a stage where commercialization has been stabilized as a whole, and as shown in Figure 3, a four-circumferential formwork 4 of steel plate or PC board is cast leaving an upright part 4a of a predetermined height, and the outside of the formwork 4 is placed. A groove 5 is formed by digging down to a predetermined level below the lower end.

The groove 5 will be a working space in the process described later. Figure 4 shows a state in which the upright portion 4a is filled with a cushioning material 15 such as foamed urethane. If you apply the soil d'' Japanese paper 16 with water, the surface will be protected and the filling will blend well.

FIG. 5 shows a group of holes 6. drilled horizontally from the lower end of the formwork 4 using the groove 5 as a working space. 6. Loosen the bottom plate before drilling the holes in the corresponding hole group 6. . . . is used as a guide to facilitate press-fitting of the bottom plate, which will be described later.

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

FIG. 6 shows the perforation group 6. . . . is used as a guide to press-fit the bottom plate steel plate 7 with a jack 9 supported by a reaction plate 8 to cover the bottom of the formwork 4.

With this, the two ruins 2 are housed in a box with a bottom.

Figure 7 shows an embodiment in which an iron □ top lid 10 is placed on the upper end of the formwork 4, and a connecting bolt 11 is inserted between the bottom cover and the bottom lid and fastened to form a portable block body. show,
""Figure 8 □ shows the state in which the block body is transported one step to a predetermined location and then turned upside down and lowered when unloading with a crane or the like.゛This is due to the work to replace the compacted soil with concrete, which will be described later.

Fig. 9 shows a mode in which the bottom cover has been removed, reinforcing concrete 14 is placed with mesh 13, etc. to integrate it, and the excavated object has been replaced on a stable foundation.

Although illustrations are omitted from now on, ``After turning it upside down again to return to the normal posture and removing the top cover 10, the cushioning material 15, Japanese paper 16, joint clay material 12, etc. as a covering are removed.
It will be restored to its original form.

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 injection into the ground. In this case, since the current-carrying area is almost always 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" According to the method of the present invention, compared to conventional means,
Because it is relocated and preserved without being dismantled, it can be preserved without causing any deformation to its original form, and it can also be saved in a short period of time and at low cost.

Claims (1)

[Claims] Consolidation is achieved by spraying and injecting a consolidating chemical into the surface of the ground to be relocated and into the ground. Next, a four-circumference form made of steel plate or PC board is driven in, leaving an upright part of a predetermined height, and the four-circumference form is A working space is formed by excavating the outside to a predetermined level below the lower end of the formwork, and cushioning material is filled in the upright parts of the formwork around the four sides.Meanwhile, the steel plate for the bottom plate is guided horizontally from the lower end of the formwork through the working space. A block body is constructed by drilling a group of drill holes and press-fitting them to cover the bottom cover, and placing an iron or PC plate top cover on the top end of the formwork, and fastening the top cover and bottom cover with bolts across the form. , This block body is transported and relocated using a crane, is lowered upside down, the bottom cover is removed, the excavated object and the concrete are integrated by concrete pouring, and the block body is turned upside down again and the top cover is removed. A method for relocating and restoring excavated objects such as ruins, which is characterized by removing formwork, cushioning material, joint clay, etc., and restoring the original shape.
