Abstract
For the purpose of sludge purification of Kyobashi River Bank, the tidal flat environmental remediational examination has conducted by using granulated coal ash(GCA). For spraying work of the GCA by heavy equipment in tidal flats which sludge deposited, temporary work floor from land area has required.
Therefore, we developed a temporary structure construction techniques using GCA.This construction technique has the unnecessary withdrawal after construction. And, as well as contribute to sediment improvement, it is possible to make the promenade, etc. By using the construction technique, we built the temporary structure for spraying the GCA.And we constructed infilation channel and permeable layer by GCA on thickness of 0.5m. After that, it was assumed that the environment of the tidal flats changes. In addition, we evaluated the construction techinique by monitoring investigation.
