Example Embodiment

[0047] The present invention will be further described below with reference to the accompanying drawings and exemplary embodiments, in which the same reference numerals in the accompanying drawings all refer to the same components. In addition, if a detailed description of the known technology is unnecessary to show the features of the present invention, it will be omitted.

[0048] Such as figure 1 with figure 2 As shown, the segmented construction method for the special-shaped single-pillar tower of the cable-stayed bridge provided by the present invention is suitable for multi-tower single-pillar towers with different cross-sectional outline shapes. The single-pillar tower includes at least those with different cross-sectional outline shapes from bottom to top. The first tower section 10, the second tower section 20 and the third tower section 30, wherein the second tower section 20 connects the first tower section 10 and the third tower section 30 to realize the shape of the ...

Abstract

The invention discloses a sectional construction method for a special-shaped single column tower of a cable-stayed bridge. A first tower section, a second tower section and a third tower section whichare different in shapes of outer profiles of cross sections are included from bottom to top, and a plurality of climbing formwork bodies are adopted to finish the pouring process of the first tower section; the number of the climbing formwork bodies is correspondingly decreased/increased at the position where the shape of the outer profile of the cross section of the second tower section changesrelative to the shape of the outer profile of the cross section of the first tower section so as to carry out the pouring process of the second tower section; and the number of the climbing formwork bodies is correspondingly decreased/increased at the position where the shape of the outer profile of the cross section of the third tower section changes relative to the shape of the outer profile ofthe cross section of the second tower section so as to finish the pouring process of the third tower section. According to the sectional construction method for the special-shaped single column towerof the cable-stayed bridge, good transition of the single column tower of the variable cross-section cable-stayed bridge at the joint of different outer profile cross-section sections can be flexiblyachieved.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a segmental construction method for a special-shaped single-column tower of a cable-stayed bridge. Background technique [0002] Due to its unique linear beauty, special-shaped structures have been more and more widely used in buildings, bridges and other structural buildings. Special-shaped structures are not only composed of straight-line structures, but often have a large number of curved structures. The entire special-shaped structure building consists of sub-structures with various cross-sectional shapes. There must be a good transition and connection between various cross-sections. Most of these special-shaped structures It is a concrete structure, and its design and construction are often difficult. [0003] However, my country's infrastructure construction is developing in depth, and the terrain conditions are becoming more and more complex. Therefore, there are more a...
