一种大口径给、排水管
摘要：
本实用新型公开了一种大口径给、排水管，所述大口径给、排水管包括钢筒、内层混凝土层、外层混凝土层、增强结构、混凝土填充结构；所述增强结构设于内层混凝土层和钢筒之间，所述增强结构具体为缠绕内层混凝土层外且外沿与钢筒焊接固定的钢带，所述外层混凝土层设于钢筒外部，所述混凝土填充结构设于内层混凝土层、钢筒和增强结构之间的空隙中。本实用新型所述的大口径给、排水管，抗腐蚀效果好，经久耐用，制作过程简单，在满足刚度和强度的同时降低重量和生产成本，具有较大的社会和经济价值。
摘要（英）：

The utility model discloses a large-caliber water supply and drainage pipe. The large-caliber water supply and drainage pipe comprises a steel cylinder, an inner concrete layer, an outer concrete layer, a strengthening structure and a concrete filling structure, wherein the strengthening structure is arranged between the inner concrete layer and the steel cylinder and is particularly a metal strip which is wound outside the inner concrete layer, and the outer edge of the metal strip is fixedly welded with the steel cylinder; the outer concrete layer is arranged outside the steel cylinder; the concrete filling structure is arranged in a gap between the inner concrete layer, the steel cylinder and the strengthening structure. The large-caliber water supply and drainage pipe is good in corrosion resistance, durable and simple in manufacturing process, and lowers the weight and the production cost while satisfying the rigidity and the strength, thereby achieving relatively high social and economic values.
