Holing construction method on PCCP pipeline site
The invention discloses a holing construction method on a PCCP pipeline site. While holing, the method implements no loss of prestress of a standard pipeline through the anchoring of prestressed wires, implements the reinforcement of the holed pipeline structure through a steel casing with branch pi...

| description | The invention discloses a holing construction method on a PCCP pipeline site. While holing, the method implements no loss of prestress of a standard pipeline through the anchoring of prestressed wires, implements the reinforcement of the holed pipeline structure through a steel casing with branch pipes and implements the seal of the opening through expansive grout and epoxy mortar. The invention has the advantages of conveniently and effectively holing a mounted PCCP standard pipeline on site so as to directly hole the mounted PCCP standard pipeline without influencing the original structure of the pipeline and damaging the functions of the pipeline, which can effectively shorten the construction period and reduce the construction cost. |
