Abstract
锛?/p>
Prestressed concrete cylinder pipe
锛?/p>
PCCP
锛?/p>
has good sealing performance
锛?/p>
corrosion resistance is strong
锛?/p>
and the advantages of long service life and has been applied in many
pipeline engineering
锛?/p>
but their pipeline length
锛?/p>
weight
锛?/p>
installation requirement is high
锛?/p>
the
construction is difficult. Hoisting
锛?/p>
docking
锛?/p>
external from the PCCP pipe grouting
锛?/p>
cathodic
protection
锛?/p>
and water pressure test PCCP pipe are introduced in the construction process of the
application of the power plant project
锛?/p>
provide important technical reference for similar projects.
