Embodiment Construction

[0039] The present invention will be further described below in conjunction with the examples. The description of the following examples is provided only to aid the understanding of the present invention. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0040] refer to figure 1 As shown, the construction method for the installation of the CFST arch bridge includes the following construction steps:

[0041] 1) Construction preparation: Prepare arch ribs 1 that meet the design curvature requirements, and connect each section of arch ribs 1 and inter-rib tie rods 2 into a whole according to the design requirements, and determine the spatial position of the CFST arch bridge by surveying and mapping;

[0042] 2) Pou...

Abstract

The invention relates to a construction method of a concrete-filled steel tube arch bridge mounting system. The construction method comprises the following construction steps: 1) preparing construction; 2) performing arch pier pouring construction; 3) connecting and positioning arch feet; 4) assembling and connecting arch ribs; 5) connecting and fixing arch rib feet; 6) mounting and positioning the wind brace; and 7) mounting and positioning the support upright. The method has the beneficial effects that the space position of the arch rib can be limited through the arch foot sleeves preset inthe arch piers, and the space positioning difficulty of the arch rib is reduced. Meanwhile, the in-pier bearing plates are preset in the arch piers, so that the influence of the arch ribs on the archpiers can be effectively reduced, and the local concentrated stress is reduced. The installed arch ribs are used as supporting stress bodies for connecting construction of the arch ribs to be installed, and the engineering quantity of field supporting system arrangement can be reduced. Meanwhile, the adjustable supporting columns and the adjustable supporting plates are arranged on the first platform plate, temporary supporting can be provided for the arch rib to be installed, and the difficulty of on-site hoisting and positioning is lowered.

Description

technical field [0001] The invention relates to a construction method for an installation system of a steel pipe concrete arch bridge, belongs to the field of bridge engineering, and is suitable for the installation engineering of a steel pipe concrete arch bridge. Background technique [0002] The concrete-filled steel tube arch bridge has a large span, a light structure, and a beautiful appearance. It is a type of bridge suitable for various terrains and social environments. However, compared with ordinary concrete girder bridges, the technology of CFST arch bridges is more complicated. There are often problems such as difficulty in supporting the construction platform, difficult control of component installation accuracy, and poor stability of arch feet, which seriously affect the construction quality and efficiency. [0003] In the prior art, there is a construction method for the hoisting system of the underwater support of a concrete-filled steel tube arch bridge, whic...
