DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention are shown in FIGS. 1 to 5. Hereinafter, the surface treatment of the soil block display surface of the present invention will be described in detail with reference to these drawings.
[0014]
First, as a stage before carrying out the surface treatment of the soil block display surface of the present invention, the work proceeds in the following procedure.
First, as a first work, a soil structure to be transferred and stored for display is cut out as a numbered soil block 20.
The soil block 20 is assumed to have a size of 3 m × 1.5 m in length and width and a thickness of about 40 to 50 cm, for example.
In addition, the soil block 20 has a gauze, spiral elastic fiber (filter material), and expanded metal stacked in order on the surface, and the soil block 20 is immersed in the resin liquid when the soil block 20 is immersed in the surface. The soil particles are prevented from eluting from the soil, and the soil block collapse is prevented.
[0015]
When the cutting of the soil block 20 and the restraining of the outer peripheral surface thereof are completed as described above, the soil block 20 is then impregnated with PEG (polyethylene glycol) at a saturated concentration (38 to 40%) at room temperature and normal pressure, for example. The soil block 20 is reinforced with After that, the soil block 20 transported to the restoration place is placed on the multi-stage silkworm shelf-type mount 70 shown in FIG. It is placed and stacked according to the number of the soil block 20.
[0016]
As described above, after the soil block 20 is appropriately fixed to the silkworm shelf 70a of the silkworm rack type pedestal 70, the surface finish of the display surface E of the soil block 20 of the present invention is performed.
First, the silkworm shelf frame material 70b surrounding the periphery of the piled soil block 20 exists vertically and horizontally on the display surface E of the restored body formed by stacking the soil blocks 20 (see FIG. 1). In order to expose the surface, for example, joint processing is performed on a horizontal joint through a process as shown in FIG.
[0017]
Note that FIG. 3 is an enlarged view of the joint portion, which will be described with reference to FIG.
[0018]
Among the joints, the horizontal joint 80 not only exposes the steel material surface of the silkworm shelf frame material 70b described above, but also has a larger dimension in the silkworm shelf 70a than the soil block 20, so that the silkworm shelf frame material is There is a gap between 70b and the soil block 20 (see FIGS. 2A, 3A, and 3B).
[0019]
Therefore, first, as a preparation for joint processing, a joint base material frame 81 having a width dimension substantially equal to the interval between the stacked upper and lower soil blocks 20 and having studs 81a (see FIG. 3C, for example, stainless steel). 2 (b) and FIG. 3 (b), bolts are fixed to the surface of the silkworm shelf frame member 70b, and the remaining gap is filled with a backup material 82 and closed.
[0020]
The surface of the joint base material 81 is coated with an epoxy resin to improve adhesion with the joint material 83 to be filled later, and further, sand particles are set before the epoxy resin is solidified. The frictional resistance is increased by spraying on the surface or attaching a fiber having irregularities on the surface.
[0021]
Next, regarding the soil block 20 above and below the joint to be treated, 38% PEG solution or epoxy resin is applied to the end face 84 in contact with the joint, and the adhesion between the soil block 20 and the joint material 83 to be filled later is applied. To improve.
[0022]
Lastly, a vasamol-shaped 38% PEG mixed soil, which is a resin mixed soil, is used as a joint material 83, and an upper and lower soil block end face 84 coated with a joint base material frame 81, a backup material 82, and a 38% PEG solution is applied. It strikes and fills the horizontal joint 80 surrounded by. If necessary, an anchor pin may be hit on the soil block end face 84 into which the PEG mixed soil is struck to enhance the adhesiveness with the joint material 83 and the slip-off prevention effect.
[0023]
Further, since the joint material is likely to flow out and drop downward in the vertical joint 90 as compared with the horizontal joint 80, first, for example, as shown in FIG. 4, the vertical joint 90 of the soil block 20 has a trapezoidal cross section. , And anchors 91 (for example, stainless nails: about 50 mm in length) are driven into the soil block end surface 92 on the joint inner surface at appropriate intervals (for example, 100 mm intervals), and 38% PEG is applied to the soil block surface in contact with the vertical joint 90. The adhesion between the joint material 93 and the soil block 20 is enhanced by applying an aqueous solution.
[0024]
Further, the backmost portion of the vertical joint is filled with a backup material 94 (for example, a sponge-like foamed rubber elastic molded product and an elastic sealing material) so that the joint material 93 does not flow out to the back of the soil block 20.
After that, the vertical joint 90 is struck and filled with the basamol-like PEG mixed soil as the joint material 93.
[0025]
After the filling of the joint material of the horizontal joint 80 and the vertical joint 90 is completed, cracks are prevented through a sufficient curing period (about two months), and strength development is enhanced. In that case, it is preferable to carry out by natural drying without performing forced drying.
[0026]
In addition, although the 38% PEG mixed soil was shown as a joint material used by said joint treatment, the soil same as a soil structure shall be extract | collected and used beforehand as a soil to mix.
[0027]
As described above, when joint processing is performed and a defect portion D such as soil peeling occurs on the display surface E side of the soil block 20 (see FIG. 5A), as shown in FIG. Apply surface treatment by applying 38% PEG solution P or epoxy resin to the inner surface of the defect part D according to the above, or after that, as shown in (c), the repair material R and the surface of the defect part D to be filled later After the anchor pin N (for example, a stainless steel nail) is driven in order to prevent interfacial delamination, the basamole-like PEG mixed soil is struck and filled as the repair material R until the surface height is almost the same as the periphery of the defect D. Do.
[0028]
Although not shown, when cracks such as hair cracks are generated on the soil block display surface E, a resin is injected at an appropriate low pressure so as not to break the bond of the soil particles, and after filling the cracks with the resin, Apply PEG mixed soil on the surface and finish.
[0029]
When the substantial repair is completed, in order to finally express the so-called earthiness, the soil block display surface E is provided with irregularities at appropriate angles and depths without making it a completely smooth surface, so that natural Close to the atmosphere of soil.
If necessary, in addition to the above, the repair portion of the soil block display surface E is colored with an inorganic pigment as a colorant that is not deteriorated by ultraviolet rays in a color scheme that matches the soil color around the repair portion.
[0030]
After finishing the joint processing and various repair work on the soil block display surface E, the clear resin is applied with a minimum amount of application so that the original color of the soil is not damaged. Prevent and complete reinforcement of the final soil block display surface E.
[0031]
In addition, the soil block cut out from the soil structure is not limited to a cube having a size of 3 to 1.5 m in length and width of about 40 to 50 cm and having a shape of about 40 to 50 cm as in this embodiment. It can be freely changed according to the size and shape of the gantry for restoration.
[0032]
In addition, in performing joint treatment and repair of a defective part, not only the PEG (polyethylene glycol) liquid shown in the present embodiment, but also any one having the same effect can be adopted, and the concentration thereof can also be If sufficient strength after reinforcement can be ensured, various concentrations can be set.
[0033]
The shape and material of the base joint frame material used in the present embodiment are not limited to those illustrated, and have a protruding portion that can appropriately prevent peeling and dropping of the filled joint material and a similar part and function, Any material can be adopted as long as the material has moderate rigidity as a whole.
[0034]
【The invention's effect】
As explained in detail above, according to the surface finishing method of the soil block display surface of the present invention, a resin such as polyethylene glycol with little temporal change is used, and the same soil as the soil block is mixed with the resin and the resin mixing is performed. Since soil will be prepared and used for various surface treatments, the temperature and humidity will increase with the passage of time after such treatment, even if conventional surface treatment methods such as coating the surface with artificial soil and coloring it are performed. In addition, problems such as drying or deterioration of the treatment layer proceeding due to the external environment such as indoor illumination light (or ultraviolet light from sunlight), and differences in color tone and surface condition between the treated area and the untreated area It is possible to solve the problem that it is likely to give a strange feeling to those who are viewing the ruins and remains.
[0035]
In addition, since there is little deterioration and deterioration of the display surface due to changes over time, it is possible to easily maintain sufficient surface strength, and there is a need for complicated work such as repair work every time the surface deteriorates In addition, it is possible to conduct efficient preservation exhibitions without waste in terms of cost and labor, and continue to reproduce the realism inherent in real earth structures (architectures, remains, etc.) over a long period of time. It becomes possible.
