A bridge with self-cleaning expansion joint device with dust-proof aprons

Abstract

The invention discloses a bridge of an automatic cleaning type telescopic joint device with a dustproof belt ring. The automatic cleaning type telescopic joint device comprises a left half frame part (3), a right half frame part (4), an upper elastic covering part (62) and a lower elastic covering part (61). The upper elastic covering part (62) and the lower elastic covering part (61) are located between the left half frame part (3) and the right half frame part (4) and used for covering telescopic joints, located on and below a road surface of the bridge, between the left half frame part (3) and the right half frame part (4) respectively. A first moving cleaning plate assembly (9) and a second moving cleaning plate assembly (8) which are arranged front and back are arranged in cavities (30 and 40) defined by the upper elastic covering part (62) and the lower elastic covering part (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 dust-proof apron. 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,...

[0003] However, this kind of covering board will inevitably be partially damaged during the driving process, and such damage is 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 longer
