本発明は、穀物、とうもろこし等を貯蔵する鉄筋コンク
リート製サイロの内面を修繕する方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for repairing the inner surface of a reinforced concrete silo for storing grain, corn, etc.
（従来技術）
一般に鉄筋コンクリ−１・製のサイロは、時間の経過に
伴い老廃化してクラックが発生したり、表層部が粉状化

、穀物等の貯蔵鮮度が保てなくなる。(Prior art) In general, silos made of reinforced concrete deteriorate over time and cracks occur, the surface layer becomes powdery, the concrete itself becomes neutral, and its watertightness and airtightness deteriorate. be lost. If the watertightness and airtightness of the silo are lost, the freshness of grains, etc., cannot be maintained.

に、従来方法で欠陥部分を補修した後に行った塗装は、
塗料とセメントとの接着力が弱いため、剥離しやすいと
いう問題があった。Furthermore, in silos, grains are fumigated to kill pests and disease bacteria that are harmful to grains, but the chemicals used in fumigation are expensive and harmful to humans, so the silos do not lose their airtightness. If these chemicals leak outside, it not only increases grain storage costs but also degrades the natural environment and causes occupational safety and health problems. Conventionally, defective parts of the silo are repaired using the silo differential pressure tightening method or visual hammering inspection, and then the inner surface is painted. However, in the former method, the inside of a sealed silo is pressurized with pressurized air, the silo is filled with fine powder, and the airflow leaking from cracks in the silo is used to transport the fine powder into the interior of the silo. Since this method allows the fine powder to arrive at the outside, there is a large amount of fine powder. In addition, the latter method involves visually detecting defects such as cracks and dents, and using hammering to investigate and repair parts that are at risk of peeling, resulting in longer construction times and higher costs. In addition to being bulky, there were problems such as a lack of reliability as defective parts could be overlooked. Furthermore, painting performed after repairing defective areas using conventional methods,
There was a problem in that the adhesive strength between the paint and cement was weak, making it easy to peel off.

することを′［ｊ「徴とする。(Structure of the Invention) The method for repairing the inner surface of a silo according to the present invention involves removing dust such as grains and corn adhering to the inner surface of the silo with a brush, brush, etc., and then projecting an abrasive material onto the inner surface of the silo to clean the inner surface of the silo. Defects are removed and exposed, caulking material is injected into the A cracks after the defects are removed, resin mortar is filled into the depressions formed by the removal of the defects, and then the inner surface of the silo is filled with resin mortar. The application of an air-impermeable refinish coating material shall be a sign.

化を図る。First, after scaffolding was placed inside the silo, dust such as grains and corn that had landed on the inside of the silo was removed by manual brushing.
Remove with a brush, etc. Next, using an impeller set projection device or a nozzle type projection device, abrasive materials such as steel particles, sand particles, resin particles, etc. are projected onto the inner surface of the silo to polish the inner surface of the silo.
This removes weak defective parts such as powdered parts, neutralized parts, and parts penetrated by grain oil and fat on the inner surface of the silo, and also roughens the inner surface of the silo and crushes the surface layer of cracks. Create a groove shape to make cracks more visible.

る。(Effects of the Invention) As is clear from the above explanation, according to the present invention, defective parts are removed especially by the projection of the abrasive material, leaving a strong part that is not fragile on the inner surface of the silo, and the surface is roughened. As a result, the adhesion of the coating film to the inner surface of the silo during subsequent painting is increased to 11. Moreover, the surface layer of the crack is fractured into a V-shaped groove, making it difficult to detect and repair the crack. Injection of caulking material becomes very easy, and in addition, weak parts are removed, and the presence of defective parts becomes clear, making it impossible to overlook them.
