Further, described protruding structure is the arc convex that is arranged on described steel band middle part.
Further, the both sides of described steel band are equipped with adhering resin layer, and are adhesively fixed between described steel band and described body internal layer and body skin.
Further, between described adhering resin layer and described steel band, be provided with oxygen barrier layer.
Further, described attachment hole is rounded or oval or kidney-shaped is circular.
Further, described attachment hole is oval, and the long axis direction of this attachment hole is positioned on the length direction of described steel band.
Further, described attachment hole is kidney-shaped circle, and the length direction of this attachment hole is positioned on the length direction of described steel band.
Further, described body internal layer and body skin all adopt polyethylene to make.
Further, the outer melting of described body internal layer and body connects as one.
The beneficial effects of the utility model are:
Potted of the present utility model strengthens composite steel band and is wound around bellows, by the compartment of terrain, both sides at steel band, attachment hole is set, not only can not destroy the physical and mechanical properties of steel band, and body internal layer and body skin can connect as one by this attachment hole, and then strengthen the join strength between body internal layer and body skin, even if be subject under the effect of long-term peristaltic forces and steel band internal stress, between pipeline lining and pipeline outer-layer also can be bonding firmly, the ring stiffness that can not destroy pipeline, can effectively improve working life.
