Problems solved by technology

However, with the passage of time, the bridge piers have been exposed to the air, and the weathering of the bridge piers is inevitable, which brings about a decrease in strength. Although collision accidents rarely occur, the partial damage to the bridge piers has brought great safety hazards.

Embodiment 1

[0026] A bridge pier protection device, comprising uprights 2 and steel wire rope nets 1, the number of said uprights 2 is at least 3, and the axes of all uprights 2 are parallel, and along the radial section of uprights 2, all uprights 2 are arranged in a regular polygon; 1 are respectively connected to two adjacent columns 2 in rotation, and the wire rope net 1 rotates around the axis of the columns 2.

[0027] In this embodiment, the column 2 is installed on the ground 3 around the pier 8, that is, the column 2 is located in the area surrounded by the protective device of the pier 8. When it is impacted by falling rocks, it mainly relies on the elastic deformation of the steel wire rope net 1 and the column 2 to offset the impact of the falling rocks. Impact force, while the rotating connection between the wire rope net 1 and the column 2 protects the wire rope net 1 from breaking due to the large instantaneous load, and also reduces the torque on the column 2 to prevent unn...

Embodiment 2

[0029] This embodiment is an improvement on the basis of Embodiment 1. The number of columns 2 is 6. On the radial section of the columns 2, the 6 columns 2 are respectively located on the 6 corner points of the regular hexagon. The same end of the 2 is hinged with an arc-shaped transverse bar 6, which can rotate around the axis of the column 2, and the concave surface of the transverse bar 6 is the side close to the wire rope net 1; the column 2 is also sleeved with a steel ball cage, steel There are several movable tubes 9 connected to the outside of the ball cage, and the alternate movable tubes 9 are connected to the same steel wire rope net 1, and a decompression spring 5 is also connected to the steel wire rope net 1, and the axis of the decompression spring 5 is perpendicular to the plane formed by the steel wire rope net 1. , the free ends of every two decompression springs 5 ​​are connected with a flexible connector 7, the flexible connector 7 is in the shape of an arc...

Abstract

The invention discloses a pier protection device which solves the problems that an existing pier protection device is complex in structure and inconvenient to maintain. The device comprises at least three stand columns and a steel wire rope net, the axes of all the stand columns are parallel, and all the stand columns are arranged in a regular polygon shape along the radial sections of the stand columns; the steel wire rope net is rotationally connected with the two adjacent stand columns, and the steel wire rope net rotates around the axes of the stand columns. The device has the advantages of being simple in structure, easy to construct, convenient to maintain, low in cost and the like.

Description

technical field [0001] The invention relates to the technical field of roads and bridges, in particular to a bridge pier protection device. Background technique [0002] The intermediate supporting structures of multi-span bridges are called piers. Bridge piers are divided into solid piers, column piers, and bent piers. According to the plane shape, it can be divided into rectangular piers, pointed piers, round piers, etc. The materials of building piers can be wood, stone, concrete, reinforced concrete, steel and so on. [0003] The pier is mainly composed of a top hat and a pier body. The abutment is mainly composed of a top hat and an abutment body. The function of the top hat is to transmit the large and concentrated force transmitted from the bridge span support to the pier body and platform body in a dispersed and even manner. Therefore, the top hat should be constructed with high-strength materials, generally not less than 200-grade reinforced concrete, and the t...
