Problems solved by technology

Since the 1990s, apart from the localization of professional production equipment, there has been no breakthrough improvement in the PCCP production process: the vertical production of PCCP tube cores is still to dismantle the tube molds on the fixed bases that are placed one by one in rows and fixed positions in the molding area. The size of the forming area and the number of pipe mold bases are determined according to the design capacity of the manufacturer. Each pipe mold base in the forming area is bypassed with a steam pipeline for steam curing after the tube core is formed.
Concrete pouring is to use the gantry crane to hang the concrete feeding tank to the blanking cone above the pipe mold that needs to be poured in the forming area, and lift the material tank up and down to complete the concrete pouring. The crane driver must have rich practical experience to perform proficient operation. The continuous uniformity is limited by the skill level of the crane driver. After demoulding, the die is lifted to the die storage area by a crane. The disassembly and assembly of the mold, the installation of the steel cylinder, the concrete pouring, and the lifting of the die depend on the crane. Manually assisted hook removal, high crane utilization rate, more labor, high labor intensity, product quality is greatly affected by human interference factors, and production efficiency is relatively low

Abstract

The invention provides a vertical type flow-line forming method for PCCP cores, which can realize flow-line production of the PCCP cores to increase the production efficiency. The method comprises the following steps: 1) designing flow lines suitable for forming the PCCP cores according to a productivity requirement; 2) performing PCCP core demoulding, including cleaning top covers and outer moulds of vertical type PCCP moulds and spraying a release agent to the top covers and the outer moulds of the vertical type PCCP moulds; 3) cleaning inner moulds and bases of the vertical type PCCP moulds and spraying the release agent to the inner moulds the bases of the vertical type PCCP moulds; 4) mounting steel cylinders and assembling the vertical type PCCP moulds; 5) pouring concrete; 6) troweling concrete at the spigot ends of the PCCP cores; and 7) curing the PCCP cores with the vertical type PCCP moulds.

Description

technical field [0001] The invention relates to a tube core molding method, in particular to a pipelined PCCP tube core vertical molding method, which belongs to the technical field of PCCP production. Background technique [0002] In 1939, the French Bonner Pipeline Company successfully developed the PCCP pipeline, and in 1942, the American Rochow Company successfully introduced it. After decades of research and development, the production technology and production equipment of the Price Brothers Company and Ameron Company are the most advanced. Representatively, an integrated system for receiving, transporting, feeding and distributing materials for steel cylinder concrete tube cores has been developed and promoted. [0003] Domestic technology started relatively late. In 1989, Shandong Electric Power Pipeline Co., Ltd. introduced PCCP pipe-making technology and key equipment from American Ameron Company. In 1992, Shenzhen Sun Pipeline Co., Ltd. introduced a complete set o...
