Connecting and sealing method for lining type prestressed concrete cylinder pipe joint
The invention provides a connecting and sealing method for a lining type prestressed concrete cylinder pipe joint. The connecting and sealing method sequentially comprises the following steps: S1, surveying and setting out; s2, a groove is excavated; s3, a prestressed concrete cylinder pipe (PCCP) is installed; s4, testing a pipeline system; and S5, flushing and disinfecting the pipeline. The pressure bearing capacity is high, and the soil covering depth is large; the sealing performance is good; the adaptability to the foundation is good; the corrosion resistance is good; the water passing performance is good; thrust can be resisted by connecting part of the pipeline; the installation is fast and convenient, and no loss exists in transportation; pipe fittings are arranged completely, and holes can be formed in pipe bodies under pressure; cost is low, service life is long, and social comprehensive benefits are good.
本发明提供了一种内衬式预应力钢筒混凝土管接头连接密封方法，依次包括以下步骤：S1、测量放线；S2、沟槽开挖；S3、预应力钢筒混凝土管PCCP安装；S4、管道系统试验；S5、管道冲洗与消毒。本发明承压能力高，覆土深度大；密封性能好；对地基的适应性好；耐腐蚀性好；通水性能好；可通过连接部分管道以抵抗推力；安装快捷、方便，运输不存在损耗；管件配备齐全，可带压管身开孔；造价低、寿命长、社会综合效益好。
