Method for manufacturing dry reinforced soil retaining wall blocks in the form of whole blocks for generation of adsorption-type atypical color patterns

The present invention relates to a method for manufacturing a dry reinforced soil retaining wall block in the form of a whole block, and in detail, spraying pigment powder with water on the inner bottom surface of a lower wall type mold in which a natural stone pattern is engraved on the inner bottom surface, and then applying wet concrete mortar to a constant After inputting in thickness, dry concrete mortar is introduced to vibrate, put a thick plate on the top of the lower wall type mold and rotate it 90°, open the side wall located at the top of the lower wall type mold, put a pallet on it and rotate it 180° so that it is upside down After that, the remaining lower wall mold is opened and demoulded to discharge and dry the dry reinforced earth retaining wall block in the form of a tubular block, and the powder is adsorbed to a certain thickness by the wet concrete mortar on the front side to create an irregular color pattern. It relates to a method for manufacturing dry reinforced soil retaining wall blocks in the form of whole blocks for pattern creation.

In general, retaining walls are built to prevent collapse of incisions cut down like cliffs when constructing roads or buildings on slopes, etc. Raise it and build a retaining wall.

These reinforced soil retaining wall blocks are constructed with reinforced soil retaining wall blocks molded to a certain size, grid reinforcement grid, tie bag, etc.) or belt-shaped reinforcement, and the advantages of the reinforced soil retaining wall blocks are structural safety of construction and easy quality control of The grid reinforcement or belt-type reinforcement is used to distribute the load evenly through mutual binding with the filled soil, is strong against differential settlement, and has good economic feasibility.

On the other hand, the reinforced earth retaining wall block is divided into a dry reinforced earth retaining wall block manufactured using low-moisture dry concrete mortar mortar and a wet reinforced earth retaining wall block manufactured using a high-moisture wet concrete mortar. Since it is manufactured, there is a problem in that it does not harmonize with the surrounding colors in the state of construction and harms the landscape.

In order to solve this problem, in the case of dry reinforced soil retaining wall blocks, coloring is impossible because side wall formwork is used, and in the case of wet reinforced soil retaining wall blocks, Korean Patent Publication No. 10-2011-0126274, colored reinforced soil retaining wall blocks using natural aggregates and As disclosed in the manufacturing method, a block for a retaining wall is prepared by adding a pigment to concrete mortar.

However, this method of adding pigment can obtain the desired color, contributing to the improvement of the aesthetics of the retaining wall, but it is difficult to express the desired color because it is mixed with concrete mortar, and the color is slightly irregular depending on the block. It is becoming.

In order to solve this problem, Republic of Korea Patent Publication No. 10-1019089 discloses a method of applying an artificial stone layer of a reinforced soil retaining wall block coated on the entire surface and a reinforced soil block for retaining wall No. 10-1628490.

The front-coated reinforced soil retaining wall block is coated with a mixture on the front surface of the manufactured block using a spray to form a color polymer coating layer to a thickness of 1 to 5 mm, so that the bonding force with concrete is excellent and chemical resistance and durability are reinforced. It is characterized in that it prevents whitening of the front part of the reinforced soil retaining wall block, does not cause discoloration or discoloration by ultraviolet rays, and maintains the same appearance and texture as high-quality natural stone with beautiful color and appearance for a long time.

In the method of applying the artificial stone layer of the reinforced soil block for the retaining wall, a plurality of reinforced soil retaining wall blocks are stacked on a moving plate so that the front part is exposed on both sides to move the moving plate, or a column bar for spraying the coating liquid on the front part of both sides of the reinforced soil retaining wall block It is movable so that the coating liquid can be applied to the front part of the reinforced soil retaining wall block, so that the worker can apply the coating liquid to the front part of the reinforced soil retaining wall block one by one. The advantage of improving the applied quality, the advantage of improving the applied quality by controlling the moving speed and distance by the motor to adjust the applied amount applied to the front of the reinforced soil retaining wall block and at the same time make the applied amount the same as the whole It is characterized in that productivity can be improved by enabling a large amount of reinforcement soil to be applied to the front of the retaining wall block at once.

However, this conventional application method increases production time and cost because the reinforced soil retaining wall block is manufactured in a wet method, cured, and then coated on the entire surface as a post-process. There is a problem in that more expensive products are applied than necessary in implementing the required function (a structure that supports a low earth pressure of 3 m or less).
