High-strength steel strip reinforced polyethylene spiral corrugated pipe

The high-strength steel strip reinforced polyethylene spiral corrugated pipe comprises a pipe body formed by winding an inner wall strip, a reinforced steel strip is spirally wound on the outer surface of the pipe body, the reinforced steel strip comprises an n-shaped steel strip main body and a pipe body, and the surface of the n-shaped steel strip main body is wound by an outer wall strip to form an outer wall layer. An upper outer wall layer lap joint extension part is arranged on one side of each outer wall layer, a lower outer wall layer lap joint extension part is arranged on the other side of each outer wall layer, and the adjacent outer wall layers are in lap joint through the upper outer wall layer lap joint extension parts and the lower outer wall layer lap joint extension parts to form a high-strength outer wall lap joint body. 本实用新型高强度钢带增强聚乙烯螺旋波纹管，包括由内壁带材缠绕成的管材本体，管材本体外表螺旋缠绕有增强钢带，增强钢带包括n型钢带主体，管材本体、n型钢带主体表面由外壁带材缠绕成外壁层，外壁层一侧设置有上外壁层搭接延长部，另一侧设置有下外壁层搭接延长部，相邻的外壁层间，通过上外壁层搭接延长部和下外壁层搭接延长部搭接形成高强度外壁搭接体。
