Embodiment Construction

[0024] refer to figure 1 , figure 2 with image 3 , the present invention is an assembled bridge pier anti-scouring device with a smooth baffle, including a pier body 2, a fixed pile 6 and an anti-scour baffle 7, and several of the fixed piles 6 are fixed in front of the pier body 2 and arranged V-shaped, the structure of the anti-scour baffle 7 is V-shaped, the anti-scour baffle 7 is fixed on the fixed pile 6, and the fixed pile 6 is a steel pipe pile, located in the V-shaped The distance between the fixed pile 6 at the top and the center of the pier body 2 is 1.5-2 times the diameter of the pier body 2, and the interval between two adjacent fixed piles 6 is 1.0-1.2 meters. The included angle of the V-shape arranged by the piles 6 is 25-40°, and the tops of the fixed piles 6 are 0.8-1.2 meters above the water surface of the river. The front of the pier body 2 is drilled with several holes arranged in a V shape. font-shaped pile hole, the depth of the pile hole is twice th...

Abstract

The invention discloses an assembly-type bridge pier erosion resisting device with a smooth baffle. The device includes a bridge pier body, multiple fixing piles and the erosion resisting baffle, thefixing piles are fixed to the front portion of the bridge pier body and arrayed in a V shape, the structure of the erosion resisting baffle is in a V shape, and the erosion resisting baffle is fixed to the fixing piles and can reduce the erosion effect of water flow on a bridge pier. The device is simple in structure, low in cost, easy in maintenance in the later period and suitable for not only protection of a newly constructed bridge pier but also supplementary protection of constructed bridge piers.

Description

【Technical field】 [0001] The invention relates to the technical field of pier anti-scouring devices, in particular to the technical field of an assembled pier anti-scouring device with a smooth baffle. 【Background technique】 [0002] In recent years, bridge disasters have occurred frequently, among which water damage is one of the most important reasons. Bridge water damage not only causes huge economic losses, but also causes casualties. Therefore, it is imperative to protect bridge piers and reduce scour. [0003] At present, there are generally two aspects of scour protection for bridge piers: active protection and passive protection. Active protection is to weaken the submerged current and horseshoe-shaped vortex that cause local scour around the pier by disturbing the water flow structure around the pier, thereby effectively reducing the scouring around the pier. Generally, there are horizontal retaining rings, pier front piles, and ring airfoil baffles. Passive prote...
