PURPOSE: A foundation reinforcing construction method for scour protection and earthquake-proof of a bridge is provided to prevent the lateral flow due to the earthquake-proof of a bridge. CONSTITUTION: A foundation reinforcing construction method for scour protection and earthquake-proof of a bridge is composed of the steps of forming a first embanking layer on the sea floor when soil is scoured around a post(2) of a bridge(3), executing the grouting under the sea floor around the post, and removing the first embanking layer if the cement is hardened after injecting the cement mortar with grouting method. The grouting is repeatedly executed so that a gap is not generated around a foundation(1) under the bridge. The scour depth which is the standard of the grouting depth is computed at 0.7~1.0 times of the maximum flood water level. |
