In the construction of pile cap of the part of the foundation,the construction scheme of double-wall steel boxed cofferdam plus anchorage without positioning by guiding barges was adopted.

Taking the construction of the elevated pile caps in deep water for main piers of Minjiang River Bridge on the newly-built Fuzhou-Xiamen Railway as an example,this paper presents the optimal design of the steel boxed cofferdam structures on the basis of mechanical analysis of the cofferdams subjected to different load cases.

The design and construction of boxed cofferdam of the Zhujiang bridge;

The double-wall steel boxed cofferdam for pylon pier No.

This paper briefs the fabrication and floating processes of the boxed cofferdams used for construction of pier bases of Paksey Bridge in Bangladesh, and describes the construction method for installation, bottom sealing and dismantling of the cofferdams without diving work.

The construction simulation analysis for suspended steel box cofferdam;

Construction technique and method of suspended steel box cofferdam are introduced in conjunction with the construction of Anqing Highway Bridge over Yangtze River.

This paper deals with the construction techniques for launching of the bottom tier of the huge steel boxed cofferdam for Pier No.

At present, steel boxed cofferdam has applied in the construction of high pile cap in deep water widely.

The main pier of the Beijiang River Bridge in the south section of the west part of Guangzhou Orbital Highway was designed as integral elevated pile cap,using steel suspending cofferdam construction technology.
