A bridge with self-cleaning expansion joint device with cam

Abstract

Disclosed is a bridge with an automatic cleaning type expansion joint device with cams. The automatic cleaning type expansion joint device comprises a left half frame component (3), a right half frame component (4), an upper elastic covering piece (62) and a lower elastic covering piece (61). The upper and lower elastic covering pieces (62 and 61) are located between the left half frame component (3) and the right half frame component (4) and used for covering an expansion joint between the left half frame component (3) and the right half frame component (4) from the positions above and below the pavement of the bridge respectively. A first mobile cleaning board assembly (9) and a second mobile cleaning board assembly (8) are arranged in cavities (30 and 40) front and back, and the cavities (30 and 40) are defined by the left half frame component (3), the right half frame component (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 with a self-cleaning expansion joint device with a cam. 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 cycl...
