A bridge with high-efficiency heat dissipation and self-cleaning expansion joint device

Abstract

The invention provides a high-efficiency cooling bridge with a self-cleaning expansion joint device. The self-cleaning expansion joint device comprises a left half frame part (3), a right half frame part (4) as well as 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 used for covering expansion joints between the left half frame part (3) and the right half frame part (4) above the payment of the bridge and under the pavement of the bridge, respectively. A first mobile cleaning plate module (9) and a second mobile cleaning plate module (8) arranged along the line from front to back are arranged in chambers (30, 40) enclosed 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 efficient heat dissipation. Background technique [0002] The bridge deck girder often needs expansion joints due to thermal expansion and contraction. In the gap of the expansion joint device facing the road, in order to prevent road debris from falling into the gap, an elastic covering plate, such as a rubber product, is provided to cover without affecting the function of the expansion joint and without affecting the driving performance. Expansion joint gap. [0003] However, it is inevitable that this kind of cover plate will be partially damaged during the driving process. Such damage is often difficult to repair in time, resulting in residues still falling into the expansion joint and affecting the normal function of the expansion joint. [0004] And cleaning up the slag in these crevices will waste manpower, and ...

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
