Abstract RU 2734727 C1

FIELD: construction.

SUBSTANCE: invention relates to construction and repair of pipelines, namely to devices for protection of joints of pipelines with ballast coating. Joint protection device pipeline with concrete coating includes paired semi-rings with mounting loops (2) on outer surface and process loops (1) on one of end surfaces. Semirings are made of concrete and include reinforcing frame (3). Reinforcing frame (3) is located inside concrete semi-ring body, is made of wire and includes embedded parts. Embedded parts consist of two plates (13) and bushing (14) located between them and placed in the through holes. Through holes are made in sites located in recesses on outer surface of side parts of semi-rings.

EFFECT: technical result consists in increase of service life of device for protection of joints of pipelines with concrete coating.
