Technical innovations adopted in industrial and civil structures and municipal works

长江水利委员会长江勘测规划设计研究院充分应用技术优势，在承担工民建与市政工程设计中大量采用了创新技术。为总结交流经验，扼要介绍了拦淤堤封闭式换填地基、软土地基中埋管及过河管桥建造、强夯与挤密砂桩消除粉细砂液化、粉煤灰堤防渗加固、连锁灌注桩及钢绞线土锚支护、全直立钢管桩码头、空箱式防洪堤、纵横竖三向预应力钢筋混凝土结构、桩顶悬挑纠倾托换、横移换梁法改造旧桥梁、深层地下洞库、高层建筑及新型悬挑结构、三维植被网快速绿化等新技术。

Taking advantage of technical superiority,Changjiang Investigation,Planning and Design Institute of Changjiang Water Resources Commission adopted a series of technical innovations in the design of industrial and civil structures and municipal works.In order to summarize and exchange experiences,the author briefly introduces some new technologies in this paper,such as excavating and refilling the foundation of silt retaining dike by means of confining curtain,pipe embedment in soft foundation and construction of pipe bridge across river,avoiding liquefaction of fine silty sand by heavy tamping and pressed sand piles,seepage prevention and consolidation of flyash dike,construction pit wall supported by serial piles and steel strand soil anchor,wharf with entirely vertical steel pipe piles,hollow box type flood dike,concrete structure prestressed in three dimensions,reconstructing old bridge with girder replaced by transverse movement,reservoir in deep cavern,high rise building and new type cantilever structure,to make green rapidly by 3 dimension vegetation net.
