钢带增强聚乙烯螺旋缠绕波纹管是一种新型塑料埋地排水管。该产品使用连续钢带压成近似A型的螺旋钢肋缠绕在内、外两层热熔接的聚乙烯层之间,把钢材的高刚度、高强度和聚乙烯的柔韧、耐腐性能结合在一起,可以使管材做到SN8,SN12.5,SN16三个环刚度等级。弥补了较大直径塑料埋地排水管只能达到SN8的限制,该产品的特点是强度高、重量轻。本文通过改进理论计算方法和施工管理,实现了超深埋设20m深,满足了工程需要,并进一步证明了该产品的突出性能和优点。
Steel reinforced polyethylene spiral wound corrugated pipe is a new type of plastic buried drainage pipe. The product uses a continuous steel strip pressed into approximately A-type spiral wound around the inner and outer two layers of heat-welded polyethylene layer, the steel high stiffness, high strength and polyethylene flexibility, corrosion resistance combined Together, can make the pipe SN8, SN12.5, SN16 three ring stiffness level. Make up the larger diameter plastic buried drain can only reach the SN8 limit, the product is characterized by high strength, light weight. In this paper, we improve the theoretical calculation method and construction management to realize the ultra-deep buried depth of 20m, which meets the engineering needs and further proves the outstanding performance and advantages of this product.
