Construction scheme of pier body and bent cap of Fengzuijiang grand bridge;

Construction technology of Jintang large Bridge non-navigable span cast-in-place pier body template

The anti-impact ability of pier body is far inferior to bearing desk.

Because of dry shrinkage,expand when hot and shrink when cold,elastic deformation and plastic deformation will happen in concrete structure,particularly serious deformation often happen during or after the construction of viaduct steel concrete pier shaft,which may threaten to the structure safety.

Based on the summarization of the fissures occurred in the wet joints of pier shaft of the Bridge and Hangzhou Bay Sea-cressing Bridge,this paper discusses the causes of the fissures,and presents countermeasures.

According to the characteristics of pier construction of Hangzhou Bay Cross - sea Bridge such as the permeation of chlorine ions and the precision requirement on the protection layer, this paper introduces a new efficient anti-erosion material, the epoxide-coated reinforcement bar, including its making, installation, storage, transport, hanging, processing and repairing, etc.

Preliminary research on the cause of the cracks in thin-walled flexible piers of continuous rigid frame bridges;
