<p>Provided is a support frame capable of preventing the leakage of a filler when a rehabilitation pipe is constructed by using segments having a variable width. The support frame for a rehabilitation pipe supports the rehabilitation pipe until the filler is hardened after the filler is injected between a pre-installed pipe and the rehabilitation pipe when the rehabilitation pipe is constructed, wherein the rehabilitation pipe is formed by connecting segments to each other in a circumferential direction and in a longitudinal direction of the rehabilitation pipe, and the segment is formed by coupling an inner plate forming the inner peripheral surface inside the pre-installed pipe, side plates provided to be erected on the edge of the circumference of the inner plate, and end plates into one body by using plastics. A part or the whole of the segment consists of two half bodies divided in the longitudinal direction of the rehabilitation pipe, and is configured to vary the width of the segment in the longitudinal direction of the rehabilitation pipe when the two half bodies are relatively moved in the longitudinal direction of the rehabilitation pipe. The support frame includes shape retaining members disposed in the circumferential direction of the rehabilitation pipe over a part or the whole of the inner surface of the rehabilitation pipe, and contacting the inner plate of the variable width segment; and support members configured to directly or indirectly support the shape retaining members.</p> |
