Abstract

A municipal bridge with guardrails capable of ascending and descending comprises a bridge base (1) and a plurality of guardrail units (2) installed on the bridge base (1). Each guardrail unit (2) comprises two fixing sleeve stand columns (4), an upper cross beam (21) and a lower cross beam (22), wherein the two fixing sleeve stand columns (4) are fixed to the bridge base (1) in a bilaterally symmetrical mode, the upper cross beam (21) and the lower cross beam (22) stretch across and extend beyond the two fixing sleeve stand columns (4), the upper cross beam (21) and the lower cross beam (22) are provided with circuit devices and are fixedly connected through vertical railings (23), screw holes in thread fit with vertical studs (43) are formed in the two fixing sleeve stand columns (4), and the upper ends of the vertical studs (43) stretch into the upper cross beam (21) and are axially and fixedly connected with the upper cross beam (21) through upper thrust bearings (431) and lower thrust bearings (432).

Description

technical field [0001] The invention relates to the field of bridges, in particular to a municipal bridge with liftable guardrails. 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 bottom of...
