Example Embodiment

[0068] Example 1

[0069] like figure 1 A combined self-balancing bridge of an arch bridge and a suspension bridge is shown, comprising a main girder structure 3, a bridge deck paved on the main girder structure 3, two arch rings 1 arranged above the main girder structure 3 and a Two main cables 7 below the main beam structure 3, one end of the main beam structure 3 is provided with a first bearing 4 for supporting it, and the other end of the main beam structure 3 is provided with a first support for supporting it. Two supports 9, one end of the arch ring 1 is fixed on one end of the main beam structure 3, the other end of the arch ring 1 is fixed on the other end of the main beam structure 3, and one end of the main cable 7 is fixed on the main beam One end of the structure 3, the other end of the main cable 7 is fixed on the other end of the main beam structure 3, the main beam structure 3 is connected to the arch ring 1 through the sling 2, and the main cable 7 is connect...

Example Embodiment

[0104] Example 2

[0105] like Figure 11 As shown, the difference between this embodiment and Embodiment 1 is that: the main beam structure 3 includes two longitudinal beams 3-1 and a plurality of cross beams 3-2 arranged between the two longitudinal beams 3-1, One end of the beam 3-2 is connected to a longitudinal beam 3-1, the other end of the beam 3-2 is connected to another longitudinal beam 3-1, and one end of the longitudinal beam 3-1 is connected to the first The support 4 is connected, the other end of the longitudinal beam 3-1 is connected to the second support 9, a bridge deck is paved on the multiple beams 3-2, and the bridge deck is laid on the bridge deck, The lower end of the sling 2 is connected to the longitudinal beam 3-1, and the upper end of the strut 6 is connected to the longitudinal beam 3-1.

[0106] In this embodiment, the stress situation of the combined self-balancing bridge of the arch bridge and the suspension bridge is that the dead load and the...

Abstract

The invention discloses a self-balancing bridge with combined arch bridge and suspension bridge. The self-balancing bridge comprises a main girder structure, a bridge floor, two arch rings and two main ropes, wherein the main girder structure is connected with the arch rings through slings, the main ropes are connected with the main girder structure through jackstays, the upper ends of the jackstays are articulated with the main girder structure, and the lower ends of the jackstays are articulated with the main ropes. The combined self-balancing bridge combines stress characteristics of an arch and the ropes, and horizontal forces of the arch, the ropes and the girder are in a self-balancing state without needing external horizontal limitation and without generating a pushing force or a pull force to the outside. The invention further discloses a construction method. The construction method comprises bridge abutment or bridge pier construction, support construction, main girder structure construction, arch ring construction, sling construction, bridge floor construction, sling tensioning, main roper construction, jackstay construction, sling force releasing and the like. The construction method effectively improves the bridge formation efficiency, reduces the construction difficulty and saves time limit for a project.

Description

technical field [0001] The invention belongs to the technical field of bridges, and in particular relates to a combined self-balancing bridge of an arch bridge and a suspension bridge and a construction method thereof. Background technique [0002] Beam bridges, arch bridges, and cable bridges are different bridge structures, and their stress characteristics are different. The girder bridge is mainly subjected to the bending of the girder, the arch bridge is mainly subjected to the compression of the arch rib, and the cable bridge is mainly subjected to the tension of the cable. The spanning capacity of arch bridges and cable bridges is greater than that of girder bridges, thanks to their ability to give full play to the performance of materials. However, arch bridges mainly under compression will generate horizontal thrust at the arch foot, and the construction of long-span arch bridges requires better geological conditions so that the foundation can resist the horizontal ...
