Embedded body of the embedding method and cavity hole of the cavity hole

摘要

PURPOSE:To obtain a filling method of cavity hole capable of easy and certain filling and a buried material at low cost by inserting a filler obtained by mixing an expanding material cubically expansible by water absorption with an aggregate into a cavity hole, and filling the cavity hole by the cubic expansion by water absorption. CONSTITUTION:Sand and earth in site are used as an aggregate, and a filler 2 obtained by mixing the aggregate with an expanding material cubically expansible by water absorption is packed in a bag 3. A buried body 1 is formed into a diameter slightly smaller than the inner diameter of a cavity hole H, and a wire 4 is connected to its top part. The wire 4 is hung on a forked wire hanger 5a provided on the top part of a bar 5, and the bar 5 is inserted into the cavity hole H, whereby the buried body 1 is inserted into the cavity hole H. Thereafter, water is injected, the expanding material of the buried body 1 is cubically expanded by water absorption to fill the cavity hole H with the filler 2, whereby the filling work of the cavity hole H is finished.
