描述信息

管壁内配置有单层或多层钢筋骨架的混凝土圆管。

混凝土与钢筋混凝土排水管产品因其良好的抗外压性能、耐久性能,以及生产成本低、制作方便、价格便宜、使用寿命长等不可替代的优势,至今在国内外市政公路建设、农田水利建设、电力和铁路工程建设及城市综合管廊建设中仍得到广泛应用,为国家基本建设发挥着巨大的作用。我国钢筋混凝土排水管行业伴随着国家基本建设的发展,经历了从小到大,从少到多,从落后到先进的不断发展过程。

混凝土和钢筋混凝土管具有抗外压强度高、耐久性好、使用寿命长、易于制造、生产成本低、价格便宜等独特优点,在我国城镇建设、工矿企业建设、农田水利建设中大量用于铺设排水管道,取得了较好的经济效益和社会效益。
