Abstract

PURPOSE: To enable early detection of accident by covering pipe line in axial direction by impermeable liquid covering and collecting leaked liquid in the covered lower part and detecting liquid leak by liquid detection means.
CONSTITUTION: A pipe line 1 is covered partially or continuously in the axial direction by impermeable liquid covering 2, and the liquid leaked from the pipe line 1 is collected at a specific place in the lower part of the covering 2. A liquid detecting means 4 is operated through the liquid collected, and a supervisory device at a base S watches the detection means 4. In this case, an introduction passage 5 for introducing leaked liquid is arranged on the inner surface of the covering 2, so even little liquid leak amount can be collected certainly. With this constitution, even little liquid leak can be detected, so accident can be detected early.
