Embodiment

[0031] The specific construction method for single-sided or double-sided corridor bridge 2 is an integrated concrete structure:

[0032] Step 1. Production of steel structure:

[0033] 1. Material management

[0034] 1.1 Steel inspection

[0035] Building structural steel must have sufficient strength, good plasticity, toughness, fatigue resistance and excellent welding performance. Must meet the following requirements:

[0036] (1) The steel grades are mainly welded H-beams. In addition to meeting the requirements of the corresponding technical standards, necessary process performance tests are still required.

[0037] (2) Certificate The steel should be accompanied by a quality certificate that meets the requirements of the design documents. If there is any doubt about the quality of the steel, it should be randomly inspected, and the results should meet the requirements of the national standards and design documents.

[0038] (3) Surface quality The depth of corrosion, ...

Abstract

The invention discloses a combined gallery bridge which comprises a middle traffic bridge, wherein gallery bridges are arranged at one side or two sides of the middle traffic bridge; the gallery bridges are parallel to the middle traffic bridge in the horizontal direction and are parallel to or in different plane crossing with the middle traffic bridge in the vertical direction; and bearing structures of bridge piers, bridge decks and gallery roofs of the gallery bridge are of integrated structures. The invention also discloses a construction method of the combined gallery bridge, which solves the problems that when the existing split constructed highway bridge is changed to the gallery bridge, the structure of the bridge deck is too thick, the earthquake resistant effect is poor and dynamic loads and static loads of river ways are difficult to be separated thoroughly.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and relates to a combined corridor bridge and a construction method thereof. Background technique [0002] Covered bridges, also known as Hongqiao, centipede bridges, etc., are bridges with a roof, which can protect the bridge, and at the same time provide shade and shelter, and provide people with rest, communication, and gathering functions. The basic combination unit of the corridor bridge is six rods, four in the vertical direction and two in the horizontal direction, and the plane is in the shape of a "well". Using the friction force generated by the compression, the components are pressed more and more tightly. This kind of structure does not require rivets, but only needs to use rods of the same specification, do not press, intersect, and overlap. From the mechanical analysis, the upper longitudinal beam is pressed on the cross beam, and the cross beam is pressed on the oppos...
