a bridge device

Abstract

Bridge equipment comprises bridge piers vertically arranged at the bottom in a spaced manner; large-tonnage adjustable supporting mechanisms are arranged on the two sides of the tops of the bridge piers; anti-seismic pot type rubber bearings are arranged at the top ends of the bridge piers; pull rods are also vertically arranged on the bridge piers; steel cables are arranged on the two sides of the pull rods; steel cable pull rod vibration absorbing protection blocks are pulled on the steel cables; the two ends of cross beams are horizontally arranged on the bridge piers; water drainage partsare arranged at the bottoms of the cross beams; and air guiding protective fences are arranged on the two sides of the cross beams.

Description

technical field [0001] The invention relates to the field of bridges, in particular to bridge equipment. Background technique [0002] At present, with the increasing number of means of transportation, highways and railways have begun to develop from the ground to the air, forming an increasing number of road bridge projects. [0003] After analysis, it is found that the existing bridge piers have the following deficiencies: first: the ability to adjust the deformation of the bridge body is weak; second: the structural life is limited; third: the space structure of the bridge piers is not fully utilized. [0004] After analysis, it is found that the existing large-tonnage adjustable support mechanism has the following deficiencies: First, the internal components are easy to wear due to heavy loads, and once worn, it is not easy to replace; Dust and impurities make it difficult for the screw to rotate; third: the cost is too high and it is not easy to operate.

Problems solved by technology

[0004] After analysis, it is found that the existing large-tonnage adjustable support mechanism has the following deficiencies: First, the internal components are easy to wear due to heavy loads, and once worn, it is not easy to replace; Dust and impurities, the screw is difficult to rotate; third: the cost is too high, and it is not easy to operate

[0005] After analysis, it is found that the existing anti-seismic basin rubber bearings have the following deficiencies: First, the connection between the top supporting structure of the traditional rubber bearing and the rubber bearing is mostly direct connection of steel bars, and the supporting structure is under pressure during long-term use Directly transmitting the pressure to the steel bar will easily lead to deformation of the steel bar, thereby reducing the seismic performance of the rubber bearing; second: when the rubber bearing is installed, it is easy to slip and be damaged; third: the rubber bearing and the bottom of the bridge Most of the supporting columns are flat contact installation, and the installation is unstable

[0006] After analysis, it is found that the existing steel cable tie rod vibration-damping protection block has the following deficiencies: first: the structural design is complicated, and it is not easy to install; second: the shock-absorbing effect is poor, and the shock-absorbing response speed is slow; and maintenance

[0007] After analysis, it is found that the existing drainage components have the following deficiencies: First, the top water inlet mechanism does not have large-scale garbage filtration treatment, which may easily lead to blockage of the drainage device; Drop; third: the bridge water is directly discharged into the river by the drainage device, which is easy to pollute the river

[0008] After analysis, it is found that the existing wind guide guardrail has the following deficiencies: first: the wind guide area is small, and the coverage is not comprehensive enough; second: when the wind is too strong, it is easy to dump; In addition to the impact caused by train running, there are no additional functions, and the functions are relatively limited
