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

Abstract

A bridge with a self-cleaning expansion joint device with a contact sensor. The self-cleaning expansion joint device includes a left half frame member (3), a right half frame member (4) and a device located on the left half frame member (3). ) and the right half frame member (4) respectively for covering the expansion joint between the left half frame member (3) and the right half frame member (4) on and under the road surface of the bridge. (62) and the lower elastic cover (61), which are surrounded by the left half frame (3), the right half frame (4), the upper elastic cover (62) and the lower elastic cover (61) The cavity is provided with a first movable cleaning plate assembly (9) and a second movable cleaning plate assembly (8) arranged in the front-to-back direction.

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...

Problems solved by technology

[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
