Funeral grave

摘要

In a conventional burial grave, in order to repeatedly use the grave, it is necessary to take out and update the remains of the burial chamber filled with the remains. In addition, it is assumed that the mortuary room is filled with scattered bones, and graves that use the mortuary room permanently are not common. In order to enable permanent use of a mortuary room, the present invention has means for promoting the weathering of remains as a result of demineralization of remains as a result of rainwater. It is characterized by having a volume of the mortuary space calculated from the set amount of calcaneus, by calculating an equilibrium point between the amount of reduced bone volume.
