Feasibility Analysis of Jacking PCCP Technical Program for Pipeline Passing Through Buildings

The PCCP(prestressed concrete cylinder pipe)-Jacking is a kind of new pipe developed by PCCP technology,and it is a ideal pipe that can be used directly as pressure pipe instead of the scheme of traditional big diameter reinforced concrete pipe with inside pressure pipe for pipeline passing through buildings.Based on the feasibility analysis of PCCP-Jacking in the Yumenkou Yellow River Diversion Project practicing,it can be drawn in this paper that PCCP-Jacking has obvious advantages including low cost,short time limit,reasonable technology and so on.It also has very good safety performance through increasing joint processing measures of PCCP-Jacking.So,it is one new technology that is worth to be studied and promoted.
