Standard Specification for Corrugated Polyethylene Pipe, 300- to 1500-mm (12- to 60-in.) Diameter
300-1500mm(12-60in.)波纹聚乙烯管标准规范直径
本规范涵盖了表面和地下排水应用中使用的波纹聚乙烯(PE)管、联轴器和配件的要求和试验方法。包括300至1500 mm的标称尺寸。规定了材料、工艺、尺寸、管道刚度、环境应力抗裂性、连接系统、脆性和标记形式。波纹聚乙烯管用于地表和地下排水应用,土壤为其柔性壁提供支撑。其主要用途是通过开放重力流收集或输送排水,如涵洞、雨水沟等。注——当聚乙烯管用于末端可能暴露的位置时,应考虑保护暴露部分,因为聚乙烯的可燃性和长期暴露在紫外线辐射下的恶化影响。
本规范不包括垫层、回填或覆土荷载的要求。本产品的成功性能取决于正确的垫层和回填类型,以及安装时的注意事项。AASHTO的LRFDBridge design Specification第12节和LFRD Bridge Construction Specification第30节分别给出了聚乙烯波纹管的结构设计和正确的安装程序。根据用户或工程师的要求,制造商应提供全面工程评估所需的剖面墙截面详图。
This specification covers the requirements and methods of tests for corrugated polyethylene (PE) pipe, couplings, and fittings for use in surface and subsurface drainage applications.Nominal sizes of 300 to 1500 mm are included.Materials, workmanship, dimensions, pipe stiffness, environmental stress crack resistance, joining systems, brittleness, and form of markings are specified.Corrugated polyethylene pipe is intended for surface and subsurface drainage applications where soil provides support to its flexible walls. Its major use is to collect or convey drainage water by open gravity flow, as culverts, storm drains, etc.Note--When polyethylene pipe is to be used in locations where the ends may be exposed, consideration should be given to protection of the exposed portions due to combustibility of the polyethylene and the deteriorating effects of prolonged exposure to ultraviolet radiation.This specification does not include requirements for bedding, backfill, or earth cover load. Successful performance of this product depends upon proper type of bedding and backfill, and care in installation. The structural design of corrugated polyethylene pipe and the proper installation procedures are given in AASHTO's LRFDBridge Design Specifications, Section 12, andLFRD Bridge Construction Specifications, Section 30, respectively. Upon request of the user or engineer, the manufacturer shall provide profile wall section detail required for a full engineering evaluation.
