The PCCP pipe core vertical molding method automatic production line comprises more than one operation lines, more than one maintenance lines, mold pushing devices, concrete loading and casting systems, mold transfer cars, transverse moving ferry vehicles, a maintenance line control system and a PLC production line control system; multiple sets of PCCP molds are arranged on the operation lines and the maintenance lines; the mold pushing devices are arranged on the operation lines and the maintenance lines; the mold transfer cars can move on the operation lines and the maintenance lines; the transverse moving ferry vehicles are matched with the operation lines and the maintenance lines; the concrete loading and casting systems are arranged on the operation lines for casting PCCP molds on the operation lines; the maintenance line control system is used for performing steam control for molds on the maintenance lines; and the PLC production line control system is used for interworking of all systems to finish prefabricating of PCCP pipe cores.

Description

technical field [0001] The invention belongs to the technical field of an automated production line, in particular to an automated production line with a PCCP tube core vertical molding method. Background technique [0002] Prestressed Concrete Cylinder Pipe (hereinafter referred to as PCCP) is a cylinder made of thin steel plate and welded with steel bearing and socket steel rings. Concrete is poured inside and outside the cylinder by the type vibration forming method or the concrete core is lined inside the cylinder by the centrifugal method, and then a precompressed stress of 70% of the tensile strength of the steel wire is applied to the outside of the concrete core to wrap the hoop high-strength steel wire (wrapped wire) The spacing is determined according to the working conditions), and then the outer layer is sprayed with a dense cement mortar protective layer to form a composite water delivery pipe. [0003] The traditional PCCP tube core vertical molding method is:...
