Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] like Figure 3-4 In this embodiment, the structural strength of the entire main arch ring 1 is increased by adding reinforcing ribs 2 on the arch back of the main arch ring 1, thereby strengthening the entire double-curvature arch bridge.

[0037] The construction steps of this embodiment are as follows:

[0038] 1. Close the bridge deck 1.6 traffic, remove the bridge deck ancillary facilities 1.7, bridge deck ancillary facilities 1.7 such as railings, sculptures or street lamps and other equipment and facilities, the facilities that are ancient cultural relics need to be properly preserved, and then use mechanical equipment to remove the bridge deck 1.6 and The filler 1.5 below the bridge deck 1.6 is chiseled out, and the vault position of the main arch circle 1 is exposed, such as image 3 shown;

[0039]2. Use high-pressu...

Abstract

The invention relates to the technical field of bridge repairing structures, in particular to a composite cover arch reinforcing method for arches of a two-way curved arch bridge. The composite cover arch reinforcing method for the arches of the two-way curved arch bridge comprises the step that a plurality of arch concrete reinforcing ribs which are as long as a main arch ring are obtained by pouring on the arch back of the two-way curved arch bridge in the bridge direction, and the structural strength of the main arch ring is enhanced through the reinforcing ribs which are arranged at intervals and protrude out of the arch back. According to the composite cover arch reinforcing method for the arches of the two-way curved arch bridge, by constructing the reinforcing ribs on the arch back of the main arch ring, a new arch rib structure located on the arch ring is formed, and the structural strength of the whole arch ring is enhanced; and navigation and traffic below the bridge are not affected, the overall appearance structure of the bridge is not damaged, and the composite cover arch reinforcing method has extremely high promotional value.

Description

technical field [0001] The invention relates to the technical field of bridge repair structures, in particular to a double-curved arch bridge arch composite arch reinforcement method. Background technique [0002] The double-curved arch bridge is a bridge with excellent structural strength and a long history of application. Its structure is as follows: Figure 1~2 As shown, the double-curved arch bridge is supported by the main arch ring 1. The main arch ring 1 is an arched structure along the bridge direction. There are multiple original beams 1.2 arranged at intervals along the bridge direction. Vertically arranged web arch walls 1.3 are installed on the original web beams 1.2. Abdominal arch walls 1.4 are installed on the web arch walls 1.4. Abdominal arches 1.4 are arranged continuously along the bridge direction. The arch 1.4 is poured with filler 1.5, the bridge deck 1.6 is laid on the filler 1.5, and then various bridge deck ancillary facilities 1.7 are arranged on th...
