Description

  The present invention relates to a wall structure of a test piece test chamber, and more particularly to a test piece wall structure of a test piece that reproduces a state in which an embankment material containing inorganic waste is buried.

  Conventionally, as a method for treating harmful inorganic wastes such as harmful substances and radioactive substances, a method for producing a banking material by adding cement and additives to these inorganic wastes and kneading them and then filling the banking material is known. It has been.

  As one of the methods for evaluating such a processing method, a CSG (Cement Sand and Gravel) material in which water and additives are added to inorganic waste and cement is kneaded, and the kneaded CSG material is filled into a mold. There is a method of molding and performing various tests such as a dissolution test using the molded product as a test piece.

  Here, the inventor of the present application simply reproduces the state by earnest research in view of the fact that it is difficult to reproduce the state in which the inorganic waste is actually landfilled in the final disposal site with the conventional test piece. A test piece manufacturing system and a test piece manufacturing method have been established (for example, Patent Documents 1 and 2).

Japanese Patent No. 5135490 Japanese Patent No. 5111673

  By the way, as a test performed using such a CSG material, a specific gravity measurement, an elution test of substances according to environmental standards related to soil contamination, an elution test of radioactive substances, etc. are mainly performed.

  However, since most of the final disposal sites are used for landfilling outdoors, in light of such circumstances, tests conducted using CSG materials include environmental tests such as low-temperature storage tests and high-temperature storage tests. It is desirable to include.

  The present invention has been made in view of the above points, and is suitable for carrying out environmental tests such as a low-temperature storage test or a high-temperature storage test, and can be easily configured.

The leakage of harmful substances contained in the test piece can be prevented.

  Therefore, in the test piece test room equipped with the wall structure of the present invention, as a test piece, in addition to a normal test piece that does not contain harmful substances, a filling material that contains harmful substances such as inorganic waste is buried. It is also possible to use a test piece to reproduce.

  Moreover, in the wall part structure of the test piece test chamber of this invention, it is preferable to provide the steel plate layer between the heat insulation layer and the outer concrete layer.

  If such a steel plate layer is provided, the heat insulation and strength of the wall structure can be further improved.

  In the wall structure of the test piece test chamber of the present invention, the inner concrete layer is preferably embedded with a water pipe through which hot water or cold water for adjusting the temperature of the internal space passes.

  In this way, by using hot water or cold water passing through the water pipes arranged in the wall structure, it is possible to easily realize a low temperature environment or a high temperature environment in the internal space and maintain it in a stable state. become able to.
