A self-cleaning bridge for expansion joints

Abstract

The invention relates to a bridge capable of automatically cleaning stretchable joints. The bridge comprises a cleaning device installed in a cavity of the stretchable joint; the cleaning device comprises a left half frame (3), a right half frame (4), an upper elastic covering piece (62) and a lower elastic covering piece (61), wherein the upper elastic covering piece (62) and the lower elastic covering piece (61) are located between the left half frame (3) and the right half frame (4), and are used for covering the stretchable joints between the left half frame (3) and the right half frame (4) on and below the road surface of the bridge respectively; and a first movement cleaning plate assembly (1) and a second movement cleaning plate assembly (8) which are arranged front and back are arranged in cavities (30 and 40) defined by the left half frame (3), the right half frame (4), the upper elastic covering piece (62) and the lower elastic covering piece (61).

Description

technical field [0001] The invention relates to a bridge with expansion joints, in particular to a bridge capable of self-cleaning the expansion joints. Background technique [0002] Due to thermal expansion and contraction of bridge deck girders, expansion joint devices are often required. In the gap facing the road surface of the expansion joint device, in order to prevent the road debris from falling into the gap, an elastic covering plate, such as rubber products, is provided to cover it without affecting the function of the expansion joint and the driving performance. Expansion joint gap. [0003] However, such covering boards will inevitably be partially damaged during the driving process, and such damages are often difficult to be repaired in time, resulting in residues still falling into the expansion joints, thereby affecting the normal function of the expansion joints. [0004] And cleaning up the slag in these gaps will also waste manpower, and the cycle is long...
