Bridge pier water guide anti-scour device and bridge and pier using water guide and anti-scour device

Abstract

The present invention provides a kind one bridge pier water-guiding scour preventing apparatus and bridge and bridge pier with the scour preventing apparatus. The bridge pier water-guiding scour preventing apparatus is set in front or periphery of bridge pier and has at least one water guiding part to guide water upward so as to avoid hollowing-out of base earth and stone in the river bed.

Description

technical field [0001] The invention belongs to a water guiding and anti-scouring device for bridge piers, and the technical field of bridges and bridge piers using the water guiding and anti-scouring devices, especially a water guiding and anti-scouring device installed on bridges and bridge piers to guide water flow and prevent river bed soil and rocks from being scoured . Background technique [0002] Press, commonly used traditional columnar piers A (such as Figure 12 As shown), the water flow B on the upstream surface is blocked by the bridge pier A, and the water flow B will show a congested phenomenon B1 on the water surface in front of the pier, and under the water surface, it will jet B2 downward along the wall of the pier A and form a vortex at the bottom C of the river bed B3, the scour pit C1 will be formed after the long-term scouring of the eddy current B3, and then the river bed C will be gradually hollowed out to expose the bottom of the pier A1. Once the fl...

Problems solved by technology

[0002] Press, commonly used traditional columnar piers A (such as Figure 12 As shown), the water flow B on the upstream surface is blocked by the bridge pier A, and the water flow B will show a congested phenomenon B1 on the water surface in front of the pier, and under the water surface, it will jet B2 downward along the wall of the pier A and form a vortex at the bottom C of the river bed B3, the long-term scouring of the eddy current B3 will form the scour pit C1, and then gradually hollow out the riverbed C to expose the bottom A1 of the pier. Once the flood washes away a large amount of water, the pier may sink, crack, or even break the bridge.

[0003] From the above explanations, we can see that no matter the structure or the effect of use of traditional bridge piers, due to the imperfect design, there are many deficiencies, which invisibly affect the safety of people's lives and property, and it is necessary to improve them as soon as possible.
