The fittings of PCCP waterline pipe,which play an important role in the wa ter delivery engineering,re-quires the project supervisor to adopt effective measures for controlling the quality and schedule of their m anufacturing.

Comparison of open channel water conveyance and PCCP pipe water conveyance;

For the PCCP pipelines of five thickness of pipeline core,this paper analyzes on the rationality of enlarging the working surface diameter of the bell and spigot faucets from aspects of the technical advantages,the aggregate alkali activity,and the comprehensive economy,etc.

This paper introduces the construction method used in the PCCP pipeline in the linkage section of YRDP of Wanjiazhai,Shanxi Province,advances some concrete measures for guaranteeing the quality and safety in the construction.

This paper describes the structure advantages,disadvantages,practical scope of the PCCP pipelines.

At present, in the water conservation and hydroelectricity general estimate budget stipulation, PCCP pipe and pressure steel pipe are taken into engineering investment as construction engineering fee and erection engineering fee separately.

The backfill grouting of lining concrete after tunnel passing through PCCP pipe is different from that of common tunnel backfill grouting.

The Research of the Key Technology of the PCCP Pipe Construction Used in Supply Water Piping Line;

Construction Technique of Using PCCP as the Mold of Tunnel Lining in South-to-North Water Transfer Project

Prestressed concrete cylinder pipe(PCCP) is a new technology for water supply project.
