Seismic structure and construction method of a municipal bridge

Abstract

The invention discloses a municipal bridge aseismic structure and a construction method, and relates to the technical field of municipal engineering. The municipal bridge aseismic structure comprisesa base. A bridge pier is fixedly connected with the top of the base, a damping box is fixedly connected with the top of the bridge pier through a first transverse plate, a damping base is fixedly connected with the bottom of the inner wall of the damping box, and a first groove is formed in the top of the damping base; and a damping device is fixedly connected with the inner wall of the first groove, a second groove is formed in the top of the damping device, and a second transverse plate is fixedly connected with the bottom of the inner wall of the second groove through a connecting block. According to the municipal bridge aseismic structure and the construction method, the structural layers of the bridge pier are increased, the aseismic capability of the bridge pier is enhanced, externalforce borne by a bridge is transferred to the damping device, and the aseismic capability of the bridge is enhanced; and the damage to the bridge is reduced, the service life of the bridge is prolonged, meanwhile the deformation degree of the device for buffering the external force is decreased, and the bridge stability is improved.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to an anti-seismic structure of a municipal bridge and a construction method. Background technique [0002] Municipal engineering refers to the construction of municipal facilities. In China, municipal facilities refer to various buildings that are set up within the planning and construction scope of urban areas and towns (townships) and provide residents with paid or free public products and services based on government responsibilities and obligations. , structures, equipment, etc., all kinds of public infrastructure construction supporting urban life belong to the category of municipal engineering, such as common urban roads, bridges, subways, such as various pipelines closely related to life: rainwater, sewage, water supply, medium Water, electricity (other than the red line), telecommunications, heat, gas, etc., as well as the construction of squares, urban greeni...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a municipal bridge anti-seismic structure and construction method, which solves the problem that the existing bridge pier structure is single, does not have good anti-seismic ability, and there is no necessary anti-seismic device in the bridge structure. The physical properties of the material should be easily damaged due to vibration. Bridge anti-seismic devices that are widely used in bridge anti-seismic applications are prone to large deformations when subjected to large forces, which need to occupy more volume of the bridge itself and affect the performance of the bridge itself.
