Bridge pier anti-collision and anti-scouring device

Abstract

The invention discloses a bridge pier anti-collision and anti-scouring device. The bridge pier anti-collision and anti-scouring device comprises a bridge pier body (1), multiple fixing piles (2), a cage frame (3) and an elastic plate (4), wherein the multiple fixing piles (2) surround the outer side of the bridge pier body (1); the fixing piles (2) are provided with flow blocking pieces (21); the steel cage frame (3) is fixed to the fixing piles (2) which are arranged at a water facing side of the bridge pier body (1); the cage frame (3) is filled with a first anti-collision body formed by irregular riprap; the elastic plate (4) is fixed to the fixing piles (2) arranged at a water backing side of the bridge pier body (1), so that a second anti-collision body is formed; water inlet holes are formed in the elastic plate(4). According to the bridge pier anti-collision and anti-scouring device disclosed by the invention, a scouring action on a bridge pier by water flow can be avoided, a collision action on the bridge pier by a collision body in water can also be avoided, the structure is simple, the cost is low, and the bridge pier anti-collision and anti-scouring device not only is suitable for the protection of newly-constructed bridge pier, but also is suitable for complementary protection of a constructed bridge pier.

Description

technical field [0001] The invention relates to the field of water building safety protection manufacturing, in particular to a bridge pier anti-collision and anti-scouring device. Background technique [0002] The scouring effect of the water flow on the pier is mainly divided into three levels: 1. The submerged current scours the bottom, which mainly refers to a part of the submerged current formed after the water flow in front of the pier hits the pier, and scours the bottom of the pier; 2. The forward water vortex ( Horseshoe-shaped vortex), mainly refers to part of the forward water flowing around the sides of the pier body after encountering the vortex of the bridge pier. After the flow passed, the boundary layer separated, forming a strong vortex at the end of the pier, washing away the end of the pier like a tornado. Traditional anti-scour measures for bridge piers can be divided into two categories according to the protection mechanism: solid anti-scour and deceler...

AI Technical Summary

Problems solved by technology

Traditional anti-scour measures for bridge piers can be divided into two categories according to the protection mechanism: solid anti-scour and deceleration and anti-scour, but both have relatively large limitations. More importantly, the above two types of protective measures focus on protecting the impact of water flow The scour of the pier, but the impact of boulders or ships on the pier cannot be avoided
