Municipal bridge structure and construction method

Abstract

The invention discloses a municipal bridge structure and a construction method, and relates to the technical field of municipal bridges. The municipal bridge structure comprises a pier and a prefabricated bridge plate installed on the pier, the prefabricated bridge plate comprises a roadway and sidewalks distributed on the two sides of the roadway, and buffer strips are arranged between the roadway and the sidewalks. Buffer ditches are formed in the buffer strips and are arranged at intervals in the length direction of the bridge surface of the prefabricated bridge plate. Buffer assemblies arearranged on the buffer strips and comprise a plurality of buffer plates arranged at intervals, energy release plates are fixedly connected to the sides, close to each other, of the buffer plates, theenergy release plates between the buffer plates are bonded and fixed, and the energy release plates between every two adjacent buffer plates form a V-shaped structure. The buffer plates are parallelto guardrails, the buffer plates are connected to the buffer strips in a sliding mode, and springs are connected between the buffer plates and the guardrails close to the buffer plates. The situationthat ab out-of-control vehicle causes danger to pedestrians on the sidewalks is relieved.

Description

technical field [0001] The application relates to the technical field of municipal bridges, in particular to a municipal bridge structure and construction method. Background technique [0002] Municipal bridges refer to bridges built on rivers, roads and road overpasses, overpasses and pedestrian bridges where roads cross railways within the city. [0003] For the structure of the existing bridge, refer to the attached Figure 4 , including bridge piers 1 and prefabricated bridge sections 24 installed on the bridge piers 1, the bridge includes a roadway 21 for vehicles to and from, and sidewalks 22 arranged on both sides of the roadway, the two side edges of the prefabricated bridge section 24 are installed with Fence 7. [0004] In the above-mentioned technology, if a car on the roadway crashes into the sidewalk 22 out of control, there is a danger to pedestrians on the sidewalk 22 . Contents of the invention [0005] In order to improve the danger caused by out-of-cont...
