Embodiment Construction

[0015] As shown in Figure 1, the device of the method for bridge pier underwater construction of the present invention is made of steel box 2, steel box bottom plate 3 and steel box inner support 7, suspension steel box beam 8, steel box cavity during construction Filled with concrete 4. The steel box 2 is slightly larger than the pier body 1. The steel box 2 is put on the pier body 1. There is a steel box bottom-sealing concrete 5 between the steel box bottom plate 3 and the pier body 1. There is a steel sleeve on the pier body 1. The box supports 7, and the upper part is provided with a suspension steel box beam 8.

[0016] The implementation method of bridge pier underwater construction of the present invention is described in detail as follows:

[0017] Process the steel casing 2 in sections and blocks in the factory or on the shore, build a floating platform on the water surface at the pier construction site, first process the bottom plate 3 of the steel casing on the pl...

Abstract

The invention discloses a method that upward construction can be made for a bridge pier which is submerged by water, which is characterized in that: a steel boxed cofferdam is applied in bridge girder base construction before sleeved into a pier body for certain length; the steel boxed cofferdam is positioned and suspended on the underwater bridge pier using a suspending beam, thereby forming a closed non-water space used for providing underwater construction operation for the pier body. The invention has the advantages of thin cofferdam, no need template, light weight, easy splice, easy demounting, small surrounding water area, convenient hoisting, assemble and demounting and small difficulty for construction compared to prior art. The invention can effectively lower filling, greatly lowering construction, saving cost and conveniently demounting and cleaning.

Description

technical field [0001] The invention relates to a bridge erection engineering method, in particular to a bridge pier underwater construction method and an auxiliary device. Background technique [0002] With the rapid development of my country's national economy, the construction of roads and railways has also developed rapidly. Therefore, bridge erection has become a key project in transportation construction, especially in the construction of small and medium river bridges. Our country has a long history of bridge construction. A number of famous bridges such as "Zhaozhou Bridge" are shining in the splendid culture of the Chinese nation for 5,000 years. At present, our country has been able to skillfully build long, long-span, deep-water foundation bridges. However, this The inventor believes that in the current construction of bridge piers in my country, especially in the construction of deep-water rapids, there are certain problems, because most of the construction of bri...
