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.

The paper mainly introduces the application quality and economical effect of wood-steel composite formwork in the bridge pier construction.

Cofferdam method is often applied for bridge pier construction in the formations with big sand-pebble particles,peripheral anti-seepage method and the construction technology are very important for anti-seepage effect.
