FIELD: construction.
SUBSTANCE: sealing of a movement joint of steel reinforced concrete (reinforced concrete) pipeline sections is arranged in a cavity at the inner side of the pipeline and comprises a metal bearing element and a flexible sealing element attached to a metal lining of sections that adjoin the joint. The bearing element is arranged in the form of separate rods located at the distance from each other with compensators in their middle part, installed in an expanded part of the joint and directed towards the outer side of the pipeline. Ends of rods are connected to each other by means of circular elements fixed to the metal lining of pipeline sections adjacent to the joint. At the same time the flexible sealing element is arranged according to the shape of the bearing element rods.
EFFECT: high tightness of a sealing and increased reliability of its operation.
