PROBLEM TO BE SOLVED: To reduce a burden of a construction cost, to reduce the environmental burden of a disposal field and to extend the life thereof by filling a cavity by filling a bag, which is carried into the cavity by humans, with a mortar obtained by treating incinerated ash of combustible waste with a special-cement-based harmless stabilizing and solidifying agent, and then by curing and hardening the same so that the cost of landfill of the disposal field can be converted to a recycling cost. SOLUTION: When the synthetic resin bag carried into the cavity is filled with the mortar obtained by treating the incinerated ash with the harmless stabilizing and solidifying agent at a detoxifying plant, a through-hole is drilled in a roof to introduce a hose to make a filled and solidified structure using a pump, so that the cavity may be filled.
