Description of the Related Art Conventionally, as a method of fixing an anchor bolt, a base material is perforated, a capsule is loaded into the hole, and the anchor bolt joined to a hammer drill or the like is inserted into the hole while rotating and striking the anchor bolt. Then, a method is known in which the container is crushed, a thermosetting resin such as an unsaturated polyester resin contained in the container is cured, and an anchor bolt is fixed (Japanese Patent Publication No. 38-12863).

降後海底において未硬化となり海洋汚染の虞があった。When this method is applied to a base material in the sea or in water or in the vicinity thereof, marine pollution due to floating of reactive monomers such as styrene monomer on the sea surface has been a problem. Also,
The surplus resin deviated from the reactive monomer deteriorated in curing and became uncured on the seabed after sedimentation, which could cause marine pollution.

A thing arises. The above-mentioned JP-A-4-27528
The described bolt fixing capsule was not a complete countermeasure because it caused floating. Further, when the specific gravity of the curable resin and the reactive monomer is 1.02 or more and less than 1.05, the suspension due to the surface tension cannot be used violently. Further, the epoxy acrylate resin is superior to the unsaturated polyester resin in terms of alkali resistance, fixing strength, etc., but since the hydrophilicity is large, the fixing strength tends to decrease and the reactive monomer tends to float more. There is.

【発明の効果】以上、詳細に述べたように、本発明を実
施することにより、海中施工において硬化性樹脂組成物
が実質的に浮遊することなく、しかも沈降した余剰樹脂
は硬化しやすく、海洋又は河川等の汚染を防止でき、し
かも、安定した固着強度を発現する画期的なボルト固着
用カプセルを提供することが出来る。As described above in detail, by carrying out the present invention, the curable resin composition does not substantially float during subsea construction, and the surplus resin that has settled easily hardens. Alternatively, it is possible to provide an epoch-making capsule for fixing bolts, which can prevent pollution of rivers and the like and can exhibit stable fixing strength.
