Design and Construction of Locking Steel Pile Cofferdam of South Tower Pile Cap for Taizhou Bridge


Article Preview

South tower of Taizhou bridge is located in complex hydrogeological conditions,the amount of its excavation engineering is large.Combined with the successful application of locking steel pipe pile cofferdam in the south tower project of Taizhou Yangtze Highway Bridge,from comparison and demonstration, scheme design and construction, process monitoring to introduce locking steel pipe pile cofferdam in detail,using the classical method and the M method to design and calculation for supporting structure.Construction practice shows that the design and calculation of support structure is accurate,locking steel pipe pile fully played its function of sealing,it also has great rigidity, good integrity strong bending resistance and other advantages.The successfully application of this technology,promoting the technological progress of bridge foundation constructionthe in deep water or complex geological conditions,it provides a basis for the construction of similar projects in the future.
