Piepline stabilizer for pipeline acrossed by river

The utility model relates to a pipeline stabilizer for a pipeline crossed by rivers, which is composed of annular balancing weight blocks (3) which are arranged on a pipeline (2) at intervals. An adhesive plaster (4) is arranged between the outer wall of the pipeline (2) and the inner wall of each annular balancing weight block (3); the upper part of each annular balancing weight block (3) is provided with a lifting hook (7). Each annular balancing weight block (3) can be composed of two symmetrical semi clamping rings (31), wherein both ends of each semi clamping ring (31) is provided with a groove (9), and a connecting hole is arranged in the groove (9); the two semi clamping rings (31) are fixedly connected by screw bolts (5) and nuts (8). The utility model has the advantage that the proportion can be ensured to reach 1.3 when the filled degree of crossing the plastic pipeline (2) is 90 percents, and also has the advantages of high stability, simple structure, convenient construction and installation, low cost and long service life. The utility model is a pipeline stabilizer for the large-caliber pipeline (2) crossed by long-distance rivers.
