Service HotlineIt can be seen that the above processing method can only be used to process a relatively simple retaining ring (that is, only a ring body, which cannot be cut or punched), and the outer surface of the processed retaining ring still cannot be guaranteed to be completely flat.
With the continuous improvement of road facilities, guardrails are set up in the middle of the roads in most cities at the separation of the upper and lower lanes. At the same time, guardrails are also set up between the motor vehicle lane and the non-motor vehicle lane. The bottom of the guardrail column is set with a base, and the base is usually made of If the steel nail is fixed, the deformation hole should be drilled on the asphalt road first, and then the steel nail should be knocked into the deformation hole. Because the outer wall of the steel nail is cylindrical, the friction force on the ground is small, and the guardrail is affected by the deformation. When the external impact force occurs, the steel nails are easily detached from the asphalt road, making the road guardrail lose its fixation. In some places, Portlandexpansion screws are used to fix the railings, but during the tightening process of the Portlandexpansion screws, the expansion pieces are opened by the force of the ejector rod, and the opening angle is small. Limited, the railing will still fall down when subjected to a large impact. Therefore, it is necessary to design a Portlandspecial screw for fixing the railing on the asphalt road.
