What is the design structure of the cast-in-situ double-sided protective wall steel mold, so that we can understand how to install correctly. Most of the cast-in-situ double-sided protective wall steel molds adopt thickened iron plate welding support, and the selection of iron plate is also very important. Generally, the high-quality Q235 plate with both strength and rigidity is selected, which has good shaping characteristics, It is also very wear-resistant. During processing, it is necessary to directly punch the cut steel plate into the design shape on the drawing, and then weld the corresponding support rib plate at the position to be reinforced to protect and resist deformation. During actual installation, check whether the pavement foundation has been roughened, which will help to improve the larger contact surface, The wall cast in this way is more solid. The bottom pavement is perforated and installed with expansion bolts to fix the wallboard molds on both sides, which can be positioned and effectively supported by screws to meet the normal construction use.
