Its purpose is to prevent out-of-control vehicles from crossing the bridge, to prevent vehicles from breaking through, under, and over the bridge, and to beautify the bridge architecture. , let’s introduce how to classify the anti-collision level of stainless steel bridge guardrails.
There are many types of stainless steel bridge guardrails. In addition to being divided by location, they can also be divided by structural characteristics, anti-collision performance, etc. According to the installation location, it can be divided into bridge side guardrails, bridge separation zone guardrails and pedestrian and lane boundary guardrails; according to structural characteristics, it can be divided into beam-column (metal and concrete) guardrails, reinforced concrete wall-type expansion guardrails and combined guardrails; According to the anti-collision performance, it can be divided into rigid guardrails, semi-rigid guardrails and flexible guardrails.
Common guardrail forms include concrete guardrails, corrugated beam guardrails, and cable guardrails. To select the form of bridge guardrails, first determine the anti-collision level based on the highway grade, taking into account factors such as safety, coordination, characteristics of objects to be protected, and on-site geometric conditions, etc., and then determine the structural form based on factors such as its own structure, economy, construction and maintenance. choose. There are three types of embedding: direct column embedded type, flange connection type, and bridge guardrail and bridge deck cast into one through force-transmitting steel bars. When conditions permit, replaceable guardrails can be used.

The inherent nature of the anti-collision guardrail lies in the materials and processing. Its appearance depends on the construction. During the construction, the construction and pile driver must be combined. Constant review and strengthening of construction ensure the installation of the corrugated beam anti-collision guardrail. When hoisting the bridge guardrail hoist 0.5 meters above the ground, check the condition of the slings. After confirming whether they are tied firmly and balanced, they can be lifted to the working surface. bridge guardrail
It is also quite certain in welding and material selection, which will achieve material isolation and make the aspects more comprehensive. The height from the ground is called the receiving aspect. Here we will focus on introducing it to you. 1. Construction, the key aspect is based on the height of the bridge from the foundation and the reinforcement of the base, which should be more beneficial. Overall height: the height measurement value is between 50-80cm, and the wall depth should be between 12-20cm thick. During the period, brick and cement construction and processing were carried out.
