Reverse supporting device for bridge gap repairing and implementation method thereof

Abstract

The invention discloses a reverse supporting device for bridge gap repairing and an implementation method of the reverse supporting device for bridge gap repairing, the reverse supporting device for bridge gap repairing comprises a supporting shell and supporting mechanisms movably installed at the two ends of the supporting shell, an operator places the supporting shell in a bridge gap, and elastic mechanisms are placed at the two ends of the bridge gap; suction cups B are sucked at two ends of the bridge gap; the supporting shell is supported for preventing sliding out of the outer end of the gap; a piston C is arranged in a suction cup opening in the upper end of the suction cup B, a movable rod is installed at the upper end of the piston C, an arc-shaped piece is installed at the upper end of the movable rod, when wind exists, the wind blows to the upper arc face and the lower arc face of the arc-shaped piece, and the flow speed of the lower arc face is lower than that of the upper arc face. According to the Bernoulli principle, a certain pressure difference is generated between the upper arc face and the lower arc face of the arc-shaped piece, so that the arc-shaped piece ascends upwards to drive the piston C to be lifted upwards, the air pressure in the suction cup B is reduced, the suction cup B is sucked more tightly, and the wind-resistant effect is good.

Description

technical field [0001] The invention relates to the technical field of bridge construction equipment, in particular to a reverse support device for bridge gap repair and an implementation method thereof. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountain streams, poor geological conditions or meet other traffic needs to erect buildings that make traffic more convenient. The role of expansion joints is to adjust the load caused by vehicles and bridge construction materials. Displacements and linkages between superstructures. Once the telescopic device of the skew bridge is destroyed, it will seriously affect the speed, comfort and safety of driving, and even cause driving safety accidents. It means that in order to meet the requirements of the ...

AI Technical Summary

Problems solved by technology

[0003] When repairing the gaps on the surface of the bridge, the gaps need to be propped open, but the existing support devices cannot automatically expand and adjust according to the size of the gaps, the stability of the supports is not strong, and the dust and other sundries remaining in the gaps cannot Clean up during the support process, affecting the repair effect
