预应力钢筒混凝土管成品检验方法

摘要

文章阐述了PCCP管成品检验抽样数量，检验项目及检验内容，详细介绍了PCCP管外观质量、尺寸偏差、管体裂缝、内压抗裂性能或外压抗裂性能、管芯混凝土抗压强度、保护层水泥砂浆抗压强度、保护层水泥砂浆吸水率、管子接头允许相对转角的检验过程方法、检验所用工具、合格判别，通过检验保证了产品质量。%This paper describes the PCCP pipe product inspection sampling number,inspection items and inspection con-tents, specifically introduces the PCCP pipe appearance quality,size deviation,tube body crack,internal pressure and crack resis-tance performance or external pressure,core concrete compressive strength,protective layer of cement mortar compressive strength,protective layer cement mortar water absorption,pipe joints allow the relative angle of the inspection process method, testing the tool,qualified judgment, the product quality is guaranteed through testing.
