Abstract

PURPOSE: To exactly discover the local rough portion or insufficiently strong portion of a continuous underground wall by forming a vertical investigating hole in the wall and investigating the insufficiently strong portion in the hole.
CONSTITUTION: A vertical investigating hole is formed in a continuous underground wall A, a water jet excavator B is inserted into the hole, and high pressure water is injected from a nozzle 7 to thereby excavate the insufficiently strong portion in the wall. Then, the state of excavated cavity C is investigated by an underwater camera or fiber scope or the like.
