Abstract

The invention discloses a manufacturing method of a concrete drainage pipe. The manufacturing method comprises the following steps: (a) preparing drainage pipe raw materials in proportion; (b) addingsodium nitrate and zinc stearate into water, and performing uniform stirring to obtain a mixed emulsion; (c) forcibly stirring cement, polypropylene fibers and lignin fibers for 1 minute to obtain a cement dry mixture, and then spraying and adding the mixed emulsion into the premix while stirring to obtain cement mixed slurry; (d) performing drying mixing of stone, fine stone, sand mud, iron tailings or copper tailings and then conveying the mixture into the cement mixed slurry to be continuously stirred and mixed, and obtaining concrete slurry; (e) mounting a pipe die, and manufacturing the drainage pipe by adopting a vertical vibration device. Through reasonable proportion design and improvement of a manufacturing process and manufacturing equipment, the concrete drainage pipe with the characteristics of high early compressive strength, reinforcement mesh corrosion resistance, good seepage and crack resistance, high compressive strength and the like is prepared, and the constructionquality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building pipes, in particular to a method for manufacturing a concrete drainage pipe. Background technique [0002] Concrete drainage pipe is an indispensable building material in urban construction projects, mainly responsible for drainage tasks such as rainwater, sewage, farmland irrigation and drainage.
