Problems solved by technology

However, with the passage of time and use, bridges and piers will be damaged due to aging, earthquakes and other natural reasons. In more cases, the impact of river water or river water and mud flow in the river will cause different degrees of damage to the bridge piers every year. and damage, especially in the rainy season when the river surges, the amount of water and mud flow in the river will increase rapidly, a large amount of flood or mud flow will have a greater impact on the pier, and the damage will be more serious. collapsed, causing the entire bridge to collapse with it.

Embodiment 1

[0032] Such as Figure 1-2 As shown, the present invention provides a protective device arranged at the upstream position of the bridge pier, including the bridge pier 3 fixed on the pier abutment 4, the upper side of the bridge pier 3 is fixed with the bridge body 2, and the upper side of the bridge body 2 is the bridge deck 1 , a protective device is provided at the upstream position of the river outside the pier 3, and the protective device includes two side guard plates 8 fixed on the protective body 7, and the two side guard plates 8 are structures made of steel materials or prefabricated reinforced concrete material, the two side guards 8 are two identical sheet structures, the sheet structures are rectangular structures or inwardly concave arc structures, and the side guards 8 of the two sheet structures are arranged radially and docked with each other The V-shaped structure together, the tip of the V-shaped structure is opposite to the direction of water flow, the tip ...

Embodiment 2

[0039] 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 5 and 6 As shown, in order to withstand the impact of larger flow velocity and flow of river water 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 rotat...

Abstract

The invention belongs to the technical field of roads and bridges, and in particular relates to a protective device at the upstream position of a bridge pier and a construction method. The invention provides a protection device arranged at the upstream position of the pier, which includes the pier fixed on the abutment, the pier is provided with a bridge body, and a protection device is provided at the upstream position outside the pier, and the protection device includes a pier fixed on the protection body The two side guards on the top, the two side guards extend radially outward, an angle is provided between the two side guards, and one ends of the two side guards are butted together or their extension lines intersect. The invention is arranged at the upstream position of the pier, and can block and divert the flood or mud flow from the upstream of the river. The process of the invention is simple and convenient to install, and can realize the purpose of protecting the safety of the bridge and improving the service life.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a protective device arranged upstream of a bridge pier and a construction method. Background technique [0002] A general bridge includes piers and bridge decks. The pier columns on the lower side of the piers are fixed on the foundation of the river. The bridge supports the bridge deck and the loads of pedestrians and vehicles on the bridge deck through the piers on the piers. The importance of the bridge piers cannot be ignored. , it must bear various loads on the upper part, and the load is reliably transmitted to the piers and river foundations. However, with the passage of time and use, bridges and piers will be damaged due to aging, earthquakes and other natural reasons. In more cases, the impact of river water or river water and mud flow in the river will cause different degrees of damage to the bridge piers every year. and damage, especially in th...
