Embodiment 1

[0043] see Figure 1-4 , the present invention provides a technical solution: a T-shaped bridge damping structure, including pier 2, a first combined pier base 5, a second combined pier base 10 and a shock absorber 15, the top of the pier 2 is provided with a bridge Surface 1, the first composite pier seat 5 and the second composite pier seat 10 are fixedly connected by connecting steel bars, and the interior of the first composite pier seat 5 and the second composite pier seat 10 is provided with an installation cavity 8, the first The side walls of the combined pier base 5 and the second combined pier base 10 are provided with inner grooves 6, and the inner wall of the bottom surface of the installation cavity 8 is fixedly installed with a chrome-plated bottom layer 9. The first combined pier base 5 and the second combined pier The top of the seat 10 is fixedly equipped with a pier side support 11, the pier side support 11 is located in the pier side groove 13, and the outsi...

Embodiment 2

[0057] Different from Embodiment 1, this paper also discloses a T-shaped bridge damping method, comprising the following steps:

[0058] S1. First observe the installation area, and then detect and calculate the internal stress of the installation area;

[0059] S2. Lay a layer of chrome-plated bottom layer 9 on the inner bottom surface of the first composite pier seat 5 and the second composite pier seat 10, and then lay a layer of loose sand and gravel particles on the chrome-plated bottom layer 9 as the shock-absorbing particle matrix 7;

[0060] S3, first drive the first combined pier seat 5 into the installation area through the positioning anchor rod 3, and drive into the depth of 2520mm, fix the position of the first combined pier seat 5, and install the pier 2 on the first combined pier seat 5 Install in the inner cavity 8, and make the pier jamb 16 snap into the inner groove 6;

[0061] S4. Horizontally push in the second combined pier base 10 from one side, so that ...

Abstract

The invention discloses a T-shaped bridge damping structure, and belongs to the technical field of bridge damping. The T-shaped bridge damping structure comprises a bridge pier, a first combined bridge pier seat, a second combined bridge pier seat and a damping frame, and the top of the bridge pier is provided with a bridge surface. According to the method, a method of combining structural damping and material damping is introduced into the method, in the using process of a common bridge, if common shock of the bridge body occurs generally, a soft sealing rubber layer, a shock particle matrix and a chromium-plated bottom layer can eliminate an internal stress generated by shock of the bridge body to the maximum extent, and the bridge body cannot be located or vibrated. When a bridge body vibrates violently due to some earthquakes or other conditions, the bridge piers can be displaced relative to the first combined bridge pier seat and the second combined bridge pier seat, at the moment, the bridge pier side columns can extrude the first damping springs and the damping frames of the inner side grooves to carry out damping, the effective damping effect on the bridge is achieved, and a good stabilizing effect can be achieved when the bridge displaces.

Description

technical field [0001] The invention belongs to the technical field of bridge shock absorption, in particular to a method for shock absorption of a T-shaped bridge. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge generally consists of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles. Today's bridges are generally erected directly through piers, but there is no installation at the bottom. With any shock-absorbing structure, after the bridge is put into use, due to the load-bearing transformation on the...
