[0088] see Figure 6 , the present embodiment provides a bridge pier anti-collision system 200, which is installed on a bridge pier 300. The bridge pier anti-collision system 200 includes a plurality of vibration-damping devices 100 and connection protection devices 210. The basic structure and principle of the vibration-damping device 100 and the resulting The technical effect is the same as that of the first embodiment. For a brief description, for parts not mentioned in this embodiment, reference may be made to the corresponding content in the first embodiment. Each vibration damping device 100 is connected to a connection protection device 210 , and the connection protection device 210 is wound around the pier 300 . A plurality of damping devices 100 are uniformly arranged on the outer peripheral surface of the bridge pier 300 .
[0089] In this embodiment, a plurality of vibration damping devices 100 are divided into multiple groups and arranged on the connection protect...

The invention provides a manufacturing method of a vibration damper and installing method of a pier anti-collision system, and relates to the technical field of a bridge safety facility. The manufacturing method of the vibration damper includes a supporting framework processing step and a shaping step; the supporting framework processing step includes steps of fixedly connecting a first bending part to a second bending part, fixedly connecting the second bending part with a third bending part, so as to form a bending frame; multiple bending frames are arranged in parallel, and one end of every bending frame is fixedly connected with the first supporting frame, and every bending frame is fixedly connected with the second supporting frame, so as to form the supporting framework. The shaping step includes the step of holding the supporting framework in an elastic holding block so as to form a damping device. Compared with the prior art, the manufacturing method of the vibration damper can manufacture the vibration damper having good vibration damping effect and capable of effectively absorbing energy generated from collision.
Description
technical field [0001] The invention relates to the technical field of bridge safety facilities, in particular to a manufacturing method of a vibration damping device and an installation method of a bridge pier anti-collision system. Background technique [0002] With the development of economy and technology, bridges have become an important part of urban roads, mountain roads, water-crossing roads, and railways. Especially for intricate urban overpasses or water-crossing bridges, the pier of the bridge often occurs to be hit and cause the bridge to be damaged and the accident of casualties. Therefore, anti-collision devices for bridge piers have been extensively studied. [0003] Existing pier anti-collision devices are varied, and most of them adopt forms such as reinforced guardrails or fences. The inventors have found through research that setting up blocks in the form of reinforced concrete pouring not only affects the appearance of the bridge and is inconvenient for...
