According to the present invention, a separated pipe structure comprises: a first outer pipe; a second outer pipe spaced from the first outer pipe at a predetermined interval along a longitudinal direction of the first outer pipe; at least one first inner pipe formed in a cavity of the first outer pipe; a second inner pipe formed in a cavity of the second outer pipe, connected to a lower part of the first inner pipe to flow fluid inside the first and the second inner pipe; and a blocking member blocking a gap between the first and the second outer pipe. In addition, the installation method of the separated pipe structure using the same includes: a step of fixating the first inner pipe inside the first outer pipe; a step of fixating the second inner pipe inside the second outer pipe; a step of installing the first outer pipe wherein the first inner pipe is fixated in a first area of an installation target object; a step of installing the second outer pipe wherein the second inner pipe is fixated at a predetermined interval from the first outer pipe in a second area in a lower side of the first area; a step of connecting the first and the second inner pipe; and a step of installing the blocking member between the first and the second outer pipe. |
