| titleOfInvention | Manufacturing method of concrete pipe |
| abstract | (57) [Summary] [Purpose] To provide a method for manufacturing a concrete pipe with excellent load bearing capacity while reducing raw material costs. (EN) Provided is a method for manufacturing a concrete pipe that can efficiently discharge internal water during manufacturing to shorten the reaction hardening time. Provide a concrete pipe manufacturing method that can prolong the service life. [Structure] Water content is about 15 to 20% after being cut into short fiber threads of about 8 mm and long fiber threads of about 20 mm or more while spraying water on a fiber material having alkali resistance and acid resistance. It is dehydrated to form a fiber yarn aggregate. For water About 1 to 3 relative to the weight of cement milk to be adjusted Cement, sand, and aggregate, if necessary, are added to the cement while stirring and mixing the short-fiber yarn and the long-fiber yarn in a substantially uniform state by adding a wt% fiber yarn aggregate and stirring. Get milk. Cement milk is put into a mold having a space portion that substantially matches a desired pipe shape, and a hardening reaction is performed while draining excess water contained therein. |
