ものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is capable of automatically and accurately measuring the thickness of a compressed body or the like obtained by compressing and reducing the volume of radioactive miscellaneous solid waste by a high pressure press. The present invention relates to a thickness measuring device for a compressed body.

このために圧縮体を最大の充填効率でドラム缶内に再充
填するには個々の圧縮体の厚み測定が必要となる。(Prior art) Non-combustible and flame-retardant miscellaneous solid wastes such as metals, plastics, rubber, and heat insulating materials generated from nuclear power plants, etc. are stored in drums and compressed and reduced by a high pressure press. In addition, several drums are packed into drums for final disposal such as burial. However, such a compressed body is not always formed to have a uniform thickness depending on the type of waste packed in the drum can and how it is packed.The center part bulges due to the springback effect, one side is thick and the other side is thin, and the center side is thin. There are various variations in shape such as depressions.
For this reason, it is necessary to measure the thickness of each compressed body in order to recharge the compressed body in the drum with the maximum filling efficiency.

た。Conventionally, the above-described compressed body is placed on a flat table, and an operator measures the thickness using a scale. However, it is not easy to accurately measure the thickness of the central portion and the peripheral portion of a large amount of the compressed body, and there is a problem that there is a risk of exposure. Therefore, it was considered to measure the thickness by the press stroke at the time of high-pressure pressing, but it was impossible to measure the thickness accurately by this method because springback of about 0 to 50 mm occurs depending on the type of waste. .
