<P>PROBLEM TO BE SOLVED: To reduce the burden on a worker in charge of measurement work by making easy and highly accurate the work for measuring a separation distance mutually between conduits buried underground. <P>SOLUTION: A separation distance measuring apparatus 100 includes a first measuring member 110 in which an indication 110a for dimension measurement is provided, and a plurality of second measuring members 120 which extend in another direction orthogonal with an extension direction of the first measuring member 110 and at least one of which is concatenated to the first measuring member 110 movable relatively to the first measuring member 110. By moving the at least one of the second measuring members 120 with respect to the first measuring member 110, mutual intervals of the plurality of second measuring members 120 can be changed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
