Description

  The present invention can be used as a material for civil engineering or construction by mixing, dissolving, and kneading the heated aggregate and the flaky modified sulfur intermediate material and solidifying the aggregate using the modified sulfur as a binder. The present invention relates to an apparatus for placing a modified sulfur solidified body that can be easily transported as a non-hazardous material, and particularly relates to a mobile modified sulfur solidified body placing apparatus that can be used on site.

  In recent years, attention has been paid to the property of sulfur, which is solid at room temperature and melts into a fluid state when heated to a predetermined temperature or more, and melts when it exceeds about 119 ° C. Attempts have been made to mix these samples and use them as materials for civil engineering and construction. The sulfur material using sulfur is sometimes referred to as sulfur concrete or sulfur solidified material because its finish and handling are apparently similar to ordinary concrete using cement (see, for example, Patent Document 1).

Sulfur materials are known as materials that have higher strength, better water barrier properties, and higher acid resistance than concrete. However, since sulfur is ignitable and treated as a hazardous material, it is melted and beaten on site. It is difficult to install. However, in the case of large offshore structures (fish reefs, algae reefs, wave-dissipating blocks, etc.) and revetment structures, it is necessary to manufacture sulfur materials near the site of use. Therefore, in order to improve such a situation, it has been attempted to produce modified sulfur by mixing and modifying a sulfur modifier as an additive to molten sulfur (see, for example, Patent Document 2).

  However, the above-described sulfur and additives used for sulfur modification (sulfur modifiers) are dangerous and difficult to transport, and the manufacturing apparatus needs to be an explosion-proof device. In addition, storage of sulfur at the production site requires a dedicated molten sulfur tank. Therefore, in order to use the sulfur material, the cost of transportation and manufacturing becomes high.

  Further, as described in Patent Document 2, the modified sulfur and fine aggregate are mixed to produce a molten modified sulfur intermediate material, or the molten modified sulfur intermediate material and It has been proposed to produce a modified sulfur solidified body by mixing and solidifying with coarse aggregate. Although this modified sulfur intermediate material and modified sulfur solidified material are treated as non-hazardous materials, since it is necessary to handle sulfur in a molten state at the time of production, the production system is a place where the molten sulfur material is stored. And all the facilities of the flowing piping system must be constantly heated to 119 ° C. or more, which is the solidification point of the molten sulfur. However, in the production of the present modified sulfur solidified body, a production system that always warms the entire equipment where the molten sulfur material is stored and flows to a predetermined temperature or higher is not provided.
