Abstract

A safety-improved bridge with a lifting railing comprises a bridge foundation (1), each guardrail unit (2) comprises two fixed sleeve pillars (4) bilaterally symmetrically (4) fixed to the bridge foundation (1), an upper crossbeam (21) and a lower crossbeam (22) both extending across the two fixed sleeve pillars (4), both the upper crossbeam (21) and the lower crossbeam (22) are provided with circuit means and are fixedly connected by vertical rails (23). Each of the two fixed sleeve pillars (4) is provided with screw holes in threaded matching with vertical screws (43), and the upper ends of the vertical screws (43) are inserted into the upper crossbeam (21) and are axially fixedly connected to the upper crossbeam (21) through an upper thrust bearing (431) and a lower thrust bearing (432).

Description

technical field [0001] The invention relates to the field of bridges, in particular to a bridge with liftable guardrails and improved safety. Background technique [0002] There are often guardrails on both sides of the road surface of the bridge to ensure traffic safety on the bridge road surface. On some bridge facilities, in order to provide lighting, aesthetics and safety indicator lights, the guardrails of bridges are often provided with electrical components such as circuits. Electrical components such as these circuits should often prevent water from entering and affecting normal use. At the same time, other devices that are easily affected by ponding or other road surface interference factors may also be installed at the bottom beam of the bridge guardrail, such as some sensing devices or beautiful decorative materials. Therefore, in some specific situations, it becomes necessary to adjust the height of the guardrail to avoid damage to the guardrail (especially the...
