A bridge with self-cleaning expansion joint device with contact sensor

Abstract

The invention discloses a bridge with an automatic cleaning expansion joint device with contact sensors. The automatic-cleaning expansion 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), wherein the upper elastic covering part (62) and the lower elastic covering part (61) are positioned between the left half frame part (3) and the right half frame part (4) and are used for covering expansion joints between the left half frame part (3) and the right half frame part (4), on and under the road surface of the bridge respectively; a first movable cleaning board assembly (9) and a second movable cleaning board assembly (8) which are arrayed in a front-rear direction are arranged in empty cavities (30, 40) encircled by the left half frame part (3), the right half frame part (4), 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 an automatic cleaning type expansion joint device with a contact sensor. Background technique [0002] The deck beams of bridges often require expansion joints due to thermal expansion and contraction. In the gap of the expansion joint device facing the road, in order to prevent the road debris from falling into the gap, an elastic covering plate, such as a rubber product, is provided to cover the expansion joint function and driving performance without affecting the performance. Expansion joint gap. [0003] However, this kind of cover plate will inevitably be partially damaged during the driving process. Such damage is often difficult to be repaired in time, and the residue will still fall into the expansion joint, thereby affecting the normal function of the expansion joint. [0004] And cleaning the slag in these gaps will also waste manpower, and the cycle is...

[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
