Problems solved by technology

However, with the passage of time and use, bridges and piers will be damaged due to natural reasons such as aging and earthquakes. In many cases, the impact of rising and falling tides in sea water and the impact of mud flow will cause varying degrees of damage to bridge piers every day. Destruction and damage, the impact of a large amount of seawater and carrying objects on the pier will be more serious due to the long time and high frequency. In severe cases, the pier will be washed away first, causing the entire bridge to collapse

Embodiment 1

[0031] Such as Figure 1-3 As shown, the present invention provides a protective device for bridge piers when the seawater is at high tide and low tide, including bridge piers 3 fixed on the piers 4, the upper side of the bridge piers 3 is fixedly equipped with a bridge body 2, and the upper side of the bridge body 2 is The bridge deck 1 is provided with two protective devices on the front and rear sides of the pier 3, each protective device includes two side guards 8 fixed on the protective body 7, and the two side guards 8 are made of steel The two side guard plates 8 are two identical sheet-like structures, the sheet-like structures are rectangular structures or concave arc-shaped structures, and the sides of the two sheet-like structures The guard plate 8 is arranged in a V-shaped structure that is radially connected to each other. The tip of the V-shaped structure is opposite to the flow direction of the rising and falling tides of the seawater. The pointed tip of the V-s...

Embodiment 2

[0038] This embodiment has been improved on the basis of Embodiment 1, and other structures are the same, and the difference is that in the protective device provided by this embodiment, such as Figure 4-5 As shown, in order to be able to withstand the impact of large flow velocity and flow seawater tide and improve the stability of the two side guards 8, a bracket 14 is provided on the rear side of the two side guards 8, and the bracket 14 is connected to the protective body 7. The bracket seat 15 is fixedly connected, and the bracket 14 is preferably a regular triangle structure. Among them, in order to allow the middle guard plate 13 to be opened and closed as required, the present embodiment does not set the insert body 11 on both sides of the middle guard plate 13 of the V-shaped structure or remove the insert body 11, and the middle guard plate 13 The lower side of the plate 13 is provided with a rotating shaft 19, so that the middle guard plate 13 can rotate with the r...

Abstract

The invention belongs to the technical field of roads and bridges, and particularly relates to a protection device for a bridge pier during tide ebbing and flowing and a construction method. The protection device for the bridge pier during tide ebbing and flowing provided comprises a bridge pier fixedly arranged on a pier platform; a bridge body is arranged on the bridge pier; protection devices are arranged on the front side and the rear side of the bridge pier; each protection device comprises two side protection plates fixedly arranged on a protection body; the two side protection plates extend outwards in a radial shape; an included angle is formed between the two side protection plates; and one ends of the two side protection plates are in butt joint together or the extension lines ofthe two side protection plates intersect. According to the protection device for the bridge pier during tide ebbing and flowing and the construction method, the protection devices are arranged at thefront side and the rear side of the bridge pier, and can block and distribute rising and falling seawater during tide ebbing and flowing, so that the safety of a bridge is protected, and the servicelife of the bridge is prolonged.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a protective device and a construction method for bridge piers when seawater ebbs and flows. Background technique [0002] Such as figure 1 As shown, a general bridge includes a bridge pier and a bridge deck. The pier column on the lower side of the bridge pier is fixed on the foundation of the seabed. The importance cannot be ignored, it must bear various loads on the upper part, and the load is reliably transmitted to the foundation of the pier and the seabed. However, with the passage of time and use, bridges and piers will be damaged due to natural reasons such as aging and earthquakes. In many cases, the impact of rising and falling tides in sea water and the impact of mud flow will cause varying degrees of damage to bridge piers every day. Damage and damage, the impact of a large amount of seawater and carrying objects on the pier will be more seri...
