A bridge with self-cleaning expansion joint device with steel brush

Abstract

The invention provides a bridge of an automatic cleaning type expansion joint device provided with steel brushes. The automatic cleaning type expansion joint device comprises a left half frame piece (3), a right half frame piece (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 piece (3) and the right half frame piece (4), and the upper elastic covering piece (62) and the lower elastic covering piece (61) are used for covering an expansion joint between the left half frame piece (3) and the right half frame piece (4) on the road surface of the bridge and below the road surface of the bridge; a first movable cleaning plate component (9) and a second movable cleaning plate component (8) which are arranged in the forward-backward direction are arranged in cavities (30,40) formed by the left half frame piece (3), the right half frame piece (4), the upper elastic covering piece (62) and the lower elastic covering piece (61) respectively.

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 steel brush. 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 ...
