摘要：
PROBLEM TO BE SOLVED: To previously prevent a fracture of a connection part of buried pipes and a leakage of a liquid from the connection part without digging out the buried pipes.
SOLUTION: This detector comprises first and second curved cylinders 5 and 6 disposed on one and the other end sides of a flexible pipe joint 4 for connecting pipes to each other, a measuring instrument 9 having a pair of detection parts 20a and 20b, a connection pipe 21 for connecting the first and second cylinders 5 and 6 to one detection part 20a, a connection pipe 22 for connecting the first and second cylinders 5 and 6 to the other detection part 20b, a connection pipe for connecting the first and second cylinders 5 and 6 to each other, and a flowing medium 23 housed in a conduit and comprising liquids of two kinds, different in specific gravity, and insoluble in each other.
