An expansion joint dust collection device and its construction method

Abstract

The invention relates to an expansion joint dust collecting device and a construction method thereof. The expansion joint dust collecting device comprises a bridge body, a bridge deck and an expansionjoint cover plate and is characterized in that a dust collecting box is arranged below the expansion joint cover plate, a dust receiving plate is arranged at the top of the dust collecting box, and tiny gravels, dust and other sundries fall downwardly through the gaps of the expansion joint cover plate onto the dust receiving plate and are guided into the dust collecting box through the dust receiving plate; when the dust quantity in the dust collecting box reaches a preset value, an alarm lamp flickers to give out an alarm to remind maintenance staff to clean the dust collecting box. The expansion joint dust collecting device has the advantages that by arranging the dust collecting box below the expansion joint cover plate, the fallen tiny gravels, dust and other sundries can be completely collected in the dust collecting box, atmospheric pollution is avoided, risks caused by the fact that the tiny gravels, dust and other sundries fall off the bridge deck, and bridge safety is increased.

Description

technical field [0001] The invention relates to the fields of bridge construction and water conservancy construction, in particular to an expansion joint dust collecting device and a construction method thereof. Background technique [0002] Existing bridges are provided with expansion joint structures at bridge deck joints, and the expansion joint structures are used to ensure that the bridge has good thermal expansion and contraction performance. The existing expansion joint structures are equipped with cover plates, and the cover plates are usually steel plates that fit together. Since the steel plates that fit together are hard links, in order to avoid the hard connection failure caused by thermal expansion and contraction, the existing technology Usually, a gap is set on the cover plate of the expansion joint, and the gap on the cover plate is used to make the cover plate have a certain fit margin to meet the requirements of thermal expansion and contraction. However, t...

AI Technical Summary

Problems solved by technology

The existing expansion joint structures are equipped with cover plates, and the cover plates are usually steel plates that fit together. Since the steel plates that fit together are hard links, in order to avoid the hard connection failure caused by thermal expansion and contraction, the existing technology Usually, a gap is set on the cover plate of the expansion joint, and the gap on the cover plate is used to make the cover plate have a certain fit margin to meet the requirements of thermal expansion and contraction. However, the existence of the gap will inevitably lead to fine sand, dust and other impurities. Objects fall from the cover of the expansion joint and fall directly under the bridge

These falling fine sand, dust and other debris not only pollute the air, but also pose certain safety hazards

In the prior art, there is no technical means to effectively intercept the fine sand, dust and other debris leaked from the expansion joint cover plate, resulting in the inability to effectively collect the sand, dust and other sundries leaked from the expansion joint
