The drainage channel steel mold is a kind of prefabricated production mold, which is a kind of steel mold. The concrete is fixed into a certain shape through the mold for use in drainage engineering. This mold is made of high-quality steel plate, through multi-channel manufacturing processes such as shear welding, and shall be uniformly polished after the mold is made, The surface of the drainage channel steel mold becomes smooth and delicate. The mold made of steel plate is very solid and is not easy to deform in use. The drainage channel steel mold is assembled by multiple templates, and each template is fixed by bolts, so it is very convenient for both assembly and disassembly. The part in contact with the mud can be coated with release agent before assembly, or the mold can be spliced before coating, but the former is not painted evenly, and then the mixed concrete can be poured into the mold, In order to fully release the bubbles in the concrete, it is a necessary step to vibrate the mud with a vibrating platform or vibrating rod. Generally, the drainage channel steel mold is produced in the prefabrication factory, because the factory environment is stable, there are too many uncontrollable factors for field production, and there is no need to worry about such problems in the factory, and the quality of prefabricated parts can be guaranteed.
