Description

  The present invention relates to a method of harmonizing the scenery of a filling joint in which the appearance of a filling joint in which mortar is filled in a gap between a bedrock, a boulder, a boulder group, a pumice stone, a pebble group, or a combination thereof, and in particular, the joint joint. The present invention relates to a method for harmonizing the scenery of a filling joint that is difficult to distinguish in appearance.

  Conventionally, in order to prevent disasters caused by rock collapse or falling rocks, rocks, boulders, boulders, floats, floats, or combinations thereof (hereinafter sometimes referred to as “rocks”) on steep slopes, There has been proposed a construction method in which a filling mortar is filled in a gap between a boulder, a boulder group, a pumice stone, a pebble group, or a combination thereof, and a rock mass or the like is fixed by the adhesive force of the filling mortar (for example, Patent Document 1, Patent) Reference 2 and Patent Document 3). In order to fill the filling mortar while preventing leakage, the gap is partially filled with a sealing mortar to form a filling joint. In addition, when the filling mortar has a high viscosity or when the filling mortar is a hard mortar, the filling gap is formed by filling the gap with the filling mortar without closing the gap with the sealing mortar. There is also.

  By filling the filling mortar into the gap of the rock mass or the like where there is a risk of rock collapse or falling rocks, the possibility of the above disaster being reduced. As the filling mortar and the sealing mortar, cement mortar or polymer cement mortar is mostly used. The surface color of the filling joint after mortar curing is approximately white to gray. For this reason, there existed a problem that the filling joint after hardening rose from surrounding scenery. In particular, in a national park, a quasi-national park, a world heritage registration site, or a candidate site thereof, the value as a tourism resource is significantly impaired if the landscape is damaged. For this reason, the technique of harmonizing the surface of a filling joint, ie, the mortar surface, and the scenery around a construction site is required.

  As a method of harmonizing the appearance of mortar and concrete with the surrounding landscape, several natural stones are planted on the concrete surface, and then debris of the same quality and color as the natural stone in the concrete surface in the gap between each natural stone and / or There are a method of laying and bonding sand (see, for example, Patent Document 4), a method of mixing colored fired aggregate and an adhesive, and spraying the construction surface (for example, see Patent Document 5).

However, there are many gaps such as bedrock filled with mortar for filling in cliffs, and it is very laborious to plant a plurality of stones in filling joints. Further, when the colored fired aggregate is mixed with an adhesive and sprayed on the construction surface, there is a problem that a colored fired aggregate must be prepared in accordance with the scenery of the construction site.

(5) On the surface of the covering material coated on the filling joints, crushed grains obtained by crushing surrounding earth and sand, stones or bedrock, earth and sand, stones or bedrock of substantially the same quality as these, or surrounding earth and sand or pebbles The method of harmonizing the scenery of the filling joint according to the above (3) or (4), wherein:

  According to the present invention, it is possible to easily harmonize the appearance of the filling joint in which the mortar is filled in the gap between the rock mass, the boulder, the boulder group, the pumice stone, the pebble group, or a combination thereof, and the scenery of the filling joint. A harmony method is obtained. In addition, according to the present invention, the appearance of the filling joint is easily harmonized with the surrounding scenery, so that it is difficult to distinguish the appearance from the appearance. Because rocks, boulders, boulders, pumice, pebble groups, or combinations of these in the vicinity of roads, private houses or tourist attractions, etc. can be fixed more reliably, securing lifelines, securing human lives, maintaining tourism resources Useful for conservation.

  The method for harmonizing the scenery of the filling joint of the present invention is a crushed grain obtained by crushing surrounding earth and sand, stones or bedrock into a filling joint filled with mortar in the gap between bedrock, boulders, boulders, floats, floats or combinations thereof. It is characterized by adhering earth and sand, stone or bedrock crushed grains, or surrounding earth and sand or pebbles substantially the same as any of these. Here, the gap between the bedrock, the boulder, the boulder group, the pumice, the pebble group, or a combination thereof includes a gap such as a crack inherent in the bedrock, the boulder or the pebble. Further, in the present invention, the filling joint means a mortar surface filled which can be observed in appearance in the opening of the gap.

  In the present invention, the method for filling the gap with mortar is not particularly limited. For example, a method of applying with a scissors or spatula, a method of injecting, a method of spraying, a method of pushing in dumpling mortar, a mortar composition (powder) contained in a paper container or a non-woven container is immersed in water together with the container A method of thrusting with a stick after that may be mentioned, and two or more of these may be used in combination. Since the mortar can be filled with less unfilled parts, the opening of the gap is closed with a sealing mortar, and then the filling mortar is placed in the gap behind the sealing mortar. A method of performing the filling step is preferred.

  In the present invention, the mortar filled in the gap is not particularly limited, and examples thereof include cement mortar, polymer cement mortar, polymer mortar, and asphalt mortar. A polymer cement mortar is preferable as the mortar to be filled in the gap because it has a large adhesive force to the bedrock and is easy to construct.

  The crushed grains obtained by crushing the surrounding earth and sand, stone or bedrock used in the present invention, the earth and sand of substantially the same quality as any of these, the crushed grains of stone or bedrock, or the surrounding earth and sand or pebbles are the bedrock or the like forming the gap and the like Use the crushed grains obtained by crushing the earth, sand, stone or bedrock, the same quality of the earth, stone or bedrock, or the earth or pebbles in the surrounding area without crushing (hereinafter referred to as "sand etc." ”Sometimes.) These crushed grains, or earth and sand or pebbles used as they are, preferably have a grain diameter of 10 mm or less. The above crushed grains having a particle diameter of more than 10 mm, earth or sand, or pebbles are not preferable because they are difficult to adhere to the filling joints. More preferable earth and sand are earth and sand having a particle diameter of 5 mm or less because they are easily bonded to the filling joint. In order to obtain earth and sand having a particle size of 5 mm or less, it is only necessary to perform sieving with a sieve having a nominal nominal size of 5 mm or less and use only the earth and sand passed through the sieve. Further, crushed grains such as earth and sand crushed to 5 mm or less by pulverization may be used. Moreover, you may use earth and sand etc. combining multiple said earth and sand etc. as needed. Preferable earth and sand etc. are the bedrock etc. which form the said gap | interval, and the earth and sand of the circumference | surroundings, stone, or the crushing particle | grains of a bedrock, or the surrounding earth and sand or pebbles.

  The earth and sand used in the present invention is preferably the same color as the rock near the filling joint because it is difficult to distinguish between the filling joint and the rock near the filling joint. As the earth and sand used in the present invention, those having substantially the same color and substantially the same quality as the bedrock and the like in the vicinity of the filling joint are more preferable because the appearance of the filling joint is in harmony with the surrounding scenery because it is more difficult to distinguish in appearance. Since the surrounding earth and sand is used as the material, there are advantages such that it is easy to obtain substantially the same color and substantially the same quality as the rock near the filling joint, the material cost is low, and the acquisition is easy. Further, it is preferable to cover the filling joint with the earth or sand because the boundary between the filling joint and the rock in the vicinity of the filling joint is difficult to distinguish in appearance. As used herein, “covering the filling joint with the earth and sand” may include a portion that is not covered to some extent as long as the filling joint can be substantially covered with the earth and sand.

  The method for adhering the earth and sand to the filling joint is not particularly limited. For example, a method of applying an adhesive to a filling joint and sprinkling or / and rubbing earth and sand before the adhesive hardens, a method of spraying adhesive and earth and sand simultaneously on the filling joint, transparent after curing, preferably colorless and transparent Or the method of apply | coating or spraying the mixture of the binder and earth and sand which become lightly colored and transparent to a filling joint, the method of sprinkling or rubbing earth etc. before the mortar of a filling joint hardens | cures. A method of applying an adhesive to a filling joint and sprinkling or / and rubbing earth and sand before the adhesive is cured, a mixture of a binder and earth and sand which are transparent, preferably colorless and transparent or lightly colored after curing, A method of applying to a filling joint, a method of sprinkling or rubbing earth or the like before the mortar of the filling joint is hardened, and the like can be performed without using a machine for bonding work.

  The adhesive that can be used is not particularly limited as long as it is water-resistant and can adhere to filling joints and earth and sand. Examples of such an adhesive include polymer adhesive mortar, polymer mortar, inorganic adhesive, organic adhesive such as unsaturated polyester resin adhesive and epoxy resin adhesive. In the case of using an adhesive, an organic adhesive is preferable because of its high adhesive force, and an adhesive that is transparent, preferably colorless, transparent or lightly colored after curing is not filled with the adhesive because the adhesive is inconspicuous. This is more preferable because the appearance of is more harmonious with the surrounding landscape.

  In addition, the method for harmony of the scenery of the filling joint of the present invention covers the filling joint in which the mortar is filled in the gap between the rock mass, the boulder, the boulder group, the pumice stone, the pebble stone group, or a combination thereof, and the covering material of the same color as the vicinity of the filling joint is coated. It is characterized by doing. In addition, the clearance gap and filling joint of a bedrock, a boulder, a boulder group, a pumice stone, a floating stone group, or these combination are the same meaning as said clearance gap and a filling joint.

  The covering material used in the present invention is substantially the same color as the vicinity of the filling joint, and can be used without particular limitation as long as it has water resistance. Examples of such a covering material include paint, polymer cement mortar, and polymer mortar. The covering material used in the present invention becomes transparent after hardening with crushed grains obtained by crushing surrounding earth and sand, stone or bedrock, earth and sand, stone or bedrock of substantially the same quality as these, or surrounding earth and sand or pebbles A mixture with a binder is preferable because it is difficult to distinguish between the filling joints and the bedrock near the filling joints in appearance. The surrounding earth and sand, stones or bedrock crushed grains used here, the earth and sand of almost the same quality, stone or bedrock crushed grains, or surrounding earth and sand or pebbles are the same as above (and above) Similarly, “Sediment” etc.) Preferable earth and sand etc. are the bedrock etc. which form the said gap | interval, and the earth and sand of the circumference | surroundings, stone, or the crushing particle | grains of a bedrock, or the surrounding earth and sand or pebbles. Moreover, as a binder which becomes transparent after curing, an organic binder such as an unsaturated polyester resin or an epoxy resin is preferable. The method for mixing the earth and sand and the binder that becomes transparent after curing is not particularly limited, and may be mixed by a mixer, but may be stirred in a container with a stick, a spatula, a kneading spoon, or the like.

  It is preferable to bond earth or the like to the surface of the covering material because it is more difficult to distinguish the boundary between the filling joint and the bedrock or the like in the vicinity of the filling joint. More preferable earth and sand are bedrock and the like surrounding the gap and the surrounding earth and sand, crushed grains of stone or bedrock, or surrounding earth and sand or pebbles. The method for adhering earth and sand to the surface of the covering material can be performed in a manner similar to the method for adhering earth and sand to the filling joint. The covering material can be used in place of the adhesive, and the earth and sand can be adhered to the surface of the covering material by sprinkling or rubbing the earth and sand before the covering material is cured.

[Example 1]
After cleaning the crack (gap) of the rock mass that is about 10 cm wide and about 3 m high in the vertical direction with a high-pressure water, it is at a position where the depth from the rock mass opening is about 10 cm. A commercially available metal lath wrapped in is installed. Next, the crack opening was closed from below while pressing the sealing mortar against the metal lath with a finger. After inserting the injection nozzle into the sealing mortar in the crack, the filling mortar was filled into the crack (gap) on the back side of the metal lath at a height of about 1 m. As a result, there was no leakage from the sealing mortar in the crack, and the filling mortar could be filled in the gap. Both the sealing mortar and the filling mortar used are Portland cement, a cement composition containing aggregates and fibers (trade name “Rock Master Powder”, manufactured by Taiheiyo Materials Co., Ltd.), a resin emulsion of styrene butadiene rubber (product) The name “Rockmaster admixture” (manufactured by Taiheiyo Materials Co., Ltd.) and polymer cement mortar mixed with water were used. These mortars differ only in the proportion of materials used. Table 1 shows the blending ratio of these mortars.

  An unsaturated polyester resin adhesive that becomes colorless and transparent after curing is applied to about half of the lower surface of the mortar for sealing the opening (that is, the filling joint), and is called before the adhesive is cured. Only the earth and sand around the crack of the bedrock that passed through a sieve having a size of 5 mm was sprinkled and rubbed with a brush, so that the earth and sand were adhered to the filling joint so that the earth and sand were covered with the earth and sand.

  After construction, when observed from a position about 20m away from the crack of the rock mass, only the part of the filling joint (lower side) where construction by the filling harmony method of the present invention was performed can be distinguished from the surrounding rock mass. It was in harmony with the surrounding landscape. In addition, the filling joint part (upper side) that has not been constructed by the method for harmony of the filling joint according to the present invention is visually discriminated from the position of the filling joint part and the rock mass from a position approximately 20 m away from the crack of the rock mass. done.

[Example 2]
An epoxy resin adhesive that becomes light yellow and transparent after curing is used as a binder on the lower half of the filling joint (width of about 10 cm, height of about 3 m) produced in the same manner as in Example 1, and this binder has a mass of 100 mass. 100 parts by mass of earth and sand around the crack of the bedrock that passed through a sieve having a nominal size of 5 mm was added to the part, and the mixture mixed with the spatula in the container was applied with the spatula. The color of the mixture used was almost the same color as the bedrock. Before the applied mixture is cured, the earth and sand around the crack of the bedrock passed through a sieve with a nominal size of 5 mm is sprinkled and then rubbed with a brush to fill the earth and sand so that the filling joint is covered with the earth and sand. Glued to joints.

  After construction, when observed from a position about 20m away from the crack of the rock mass, only the part of the filling joint (lower side) where construction by the filling harmony method of the present invention was performed can be distinguished from the surrounding rock mass. It was in harmony with the surrounding landscape. In addition, the filling joint part (upper side) that has not been constructed by the method for harmony of the filling joint according to the present invention is visually discriminated from the position of the filling joint part and the rock mass from a position approximately 20 m away from the crack of the rock mass. done.

The landscape joint harmony method of the filling joint of this invention can be used suitably for the construction for preventing a falling rock and a rock fall. In particular, the rocks, boulders, boulders, boulders, boulders, or a combination of these in the vicinity of roads, private houses, tourist attractions, etc. can be more securely fixed and harmonized with the surrounding landscape. It is useful for securing, securing lives, and maintaining and conserving tourism resources.
