PIPELINE LAYING SYSTEM Russian patent published in 2015 - IPC B23P19/00 

FIELD: construction.

SUBSTANCE: pipeline laying system (100) can comprise the device (102) for laying outside of the tunnel which includes a frame (104), laying devices and a mobile clamping device (106) in the sliding engagement with the device frame for laying. The drive can induce the mobile clamping device linked to the pipeline between the first position (108) and the second position (110) along the frame. In the tunnel the system can also comprise a set of supporting frames (118) located at a distance from the laying device and mutually spaced which support the pipeline on supports when the pipeline forces is pushed (or extended) by means of the laying device through holes of the set of housing segments (122) mounted in the tunnel. The controller (126) is implemented with a possibility of control of the drive and the mobile clamping device, according to converters which measure slipping of the pipeline, the axial force and the clamping pressure. Also two pipeline laying methods are offered.

EFFECT: overall pipeline laying performance increases.
