Problems solved by technology

[0007] However, in the comparison document, only a set of buffer springs are used for shock absorption. The long-term vibration and extrusion of the bridge to the base will cause the springs to lose their elasticity, and then lose the effect of shock absorption. The shock absorption effect is not good.

Embodiment Construction

[0065] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0066] The utility model relates to a bridge, which is a high-pier bridge used for high-speed rail operation.

[0067] Such as figure 1 As shown, it includes a high pier 1, a support 2, a body 3 and a foundation for supporting the body 3.

[0068] The main body 3 is fixedly installed on the foundation, and rails for high-speed rail operation are installed on the main body 3. There is a bridge arch at the bottom of the main body 3, which can quickly divert strong wind through the bridge arch, increase the stability of the main body, and improve the overall body 3. of stability.

[0069] The support 2 is fixed between the main body 3 and the high pier 1 through embedded parts.

[0070] refer to figure 2 and image 3 , the support 2 includes an upper support plate 21, a lower box seat 22 and 2 groups of shock absorbers 4 arranged side by side, a cavity is ...

Abstract

The invention discloses a bridge. The bridge comprises a high pier, a support and a body; the high pier is connected with the bottom of the body through the support; the support comprises an upper support plate and a lower box seat; a rail for a high speed train to run is arranged on the body; a vibration eliminating device for absorbing and eliminating the vibration of the body is arranged in thesupport; the vibration eliminating device comprises two spherical rotating blocks which are symmetric to each other at the top and the bottom; the upper spherical rotating block is fixedly connectedwith the support support plate; the lower spherical rotating block is fixedly connected with the lower box seat; the upper spherical rotating block and the lower spherical rotating block are propped against each other; and a vibration absorbing structure for absorbing the vibration of the body is arranged in the high pier. The bridge has the advantages of high stability, perfect body supporting effect, vibration absorption and practicability.

Description

technical field [0001] The invention relates to the field of transportation roads, in particular to a bridge. Background technique [0002] With the rapid development of high-speed railways in the world, the problem of dynamic vibration between trains and bridges has been highly valued. [0003] The high-speed train will have a dynamic impact on the bridge, which will affect the working condition and service life of the bridge. [0004] At the same time, the vibration of the bridge will affect the stability and safety of the train when it is running. With the continuous development of the railway system, the complexity of my country's terrain makes the construction of many deep-water high-pier bridges inevitable, which also brings many engineering problems to the bridge construction. [0005] The Chinese patent with the application number CN201520277398.3 and the authorized announcement date of April 27, 2015 discloses an anti-collision and shock-absorbing bridge base, inc...
