FIELD: machine building. ^ SUBSTANCE: invention refers to auxiliary devices used at repair and reconstruction of pipelines. Support device (1) is designed for support of a working pipe (L) when filling material is laid between internal peripheral surface of an existing pipe (K) and external peripheral surface of a new working pipe (L) inserted into the existing pipe (K). Support device (1) consists of frame (2), of support element (3) mounted on frame (2) and of transfer facility (4). Support element (3) also consists of support sections (32, 34, 35) transferred between a supporting position for holding the working pipe (L) and an initial position separated from the working pipe (L). When support sections (32, 34, 35) are in the initial position, the transfer facility (4) can move contacting internal peripheral surface of the working pipe (L). ^ EFFECT: carrying out repair without assembly and disassembly of support device at its transfer into next section. ^ 8 cl, 16 dwg |
