Problems solved by technology
However, since the pipe body suspended in the water lacks a platform for installing the damper, the damper of the anchor cable can be fixed on the seabed foundation, but the installation water level is deep, and the construction is difficult, which is not conducive to daily equipment inspection and maintenance

Embodiment
[0023] Embodiment: a kind of floating tunnel body disk vibration suppressor, such as Figure 1-4 As shown, the pipe body of the floating tunnel is composed of pipe sections 1 connected end to end, and the pipe section 1 is used as a section of the floating tunnel to undertake vehicle traffic. The main structure of the present invention includes an anchor plate 2 , a vertical damper 3 , a T-shaped bar 4 , an anchor cable damper 5 , a node block 6 , a connecting column 7 , and a disc 8 .
[0024] Among them, the anchor plate 2 is an arc-shaped steel plate, which fits the bottom of the pipe section 1 and is fixedly connected by high-strength bolts. The anchor cable 9 is an anchoring device for the floating tunnel body. One end is connected to the floating tunnel body, and the other end is fixed on the underwater foundation.
[0025] The top of the vertical damper 3 is hinged in the middle of the bottom of the anchor plate 2, so that it has a small amount of rotational freedom in ...

The invention discloses a tube body disk vibration suppressor for a floating tunnel. The tube body is spliced by tube sections, the anchor cables are respectively arranged on both sides of the tube section, and the anchor plates are arc-shaped and fixedly attached to the The bottom of the pipe section; the middle of the bottom of the anchor plate is provided with a vertical damper, the bottom of the vertical damper is connected to a node block, and the bottom of the node block is connected to a disc through a connecting column; Both sides of the length direction of the pipe section are respectively provided with T-shaped bars. The ends of the crossbars are vertically connected to the anchor cables. The invention has a clear structure and reliable performance, can inhibit the vibration of the anchor cable and the pipe body of the floating tunnel in water, and is convenient for installation and maintenance. In addition, the present invention adds a disc structure, which can provide a platform for monitoring and maintenance, travel, escape and so on.
Description
technical field [0001] The invention relates to the technical field of civil engineering, in particular to a tube body disk vibration suppressor for a suspended tunnel. Background technique [0002] The floating tunnel is mainly composed of pipe body, anchor cable, foundation, revetment section, etc. It has the advantages of good economy, large spanning capacity, all-weather operation and environmental protection. As a future traffic structure, it is considered to be the most challenging and potential new traffic structure in the 21st century. But there is no floating tunnel built example in the world at present. Research on its mechanical properties in complex environments, especially the suppression of vortex-induced vibrations, has yet to be developed. [0003] The long-term continuous vibration of the structure will undoubtedly accelerate fatigue damage and bring about other safety problems of mechanical structures. The anchor cables and pipe sections, which are impor...
