Abstract

The invention discloses a non-support turnover form construction technology for highway bridge thin-wall piers. The non-support turnover form construction technology has obvious superiority and scientificity in thin-wall pier construction. Compared with support construction, the technology is advantaged by labor saving, material saving, and fast speed. The technology improves construction safety factors while creating good economic benefits.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a formwork construction technology for thin-walled piers of highway bridges without supports. Background technique [0002] In recent years, the expressways in western my country have developed rapidly, and the highway construction has begun to extend to mountainous areas. However, in these areas, the mountains are steep, the height difference is large, and the site is narrow, which makes a large number of high pier structures used in bridge construction. The commonly used support construction requires a large number of scaffolds, which not only consumes a lot of manpower and material resources, but also has complicated procedures, slow progress, and low safety factor. Contents of the invention [0003] The object of the present invention is to provide a kind of construction technology of the thin-walled pier of highway bridge without support, which has solved the proble...
