How to use the prefabricated square culvert mold: brush a layer of oil or release agent in the prefabricated square culvert mold, then pour the mixed cement or concrete into the prefabricated square culvert mold, vibrate with a vibrating rod to remove air bubbles in the cement, It takes about 24 hours for concrete to set and demould at the initial stage. The requirements of large-scale engineering construction in modern society for molds: mold accuracy and smoothness are required to be high; the contact surface with concrete should use a smoothness of 1.6 or more, and the upper plate; the socket surface should be milled as a whole; after manufacturing, stress treatment to prevent deformation; mold The rigidity requirements of the concrete are determined by the working performance of the concrete and the auxiliary vibration force, and the design should be calculated according to the molding method before manufacturing.
