Research on Structural Characteristics and Construction Technologies of Piles Wharf Assembled with Prefabricated Units
In view of the advantage in the structure and the technical advancement of the assemble piled wharf,a comparative study was carried out from the aspects of basic structure,digital design,key construction technology and project cost,which verified the main structural characteristics,technical and economic advantages of the assembled wharf in comparison with the traditional piled wharf.The research results show that the proportion of the prefabricated concrete units such as the prefabricated crossbeams and slab beams reaches nearly 80%in comparison with 30%of the traditional structure.The forward design based on digital technologies applies to the module structure of the assemble piled wharf,which supports the automated drawing and high-speed calculation function,greatly raises the efficiency of the wharf structure design.The crossbeams of the assembled piled wharf are constructed by using the prefabricated cavity method and the steel section as pile core.The sheet beams require single-sided positioning and guided installation based on the crossbeams,which effectively improves the structure integrity and construction efficiency.Compared with the traditional piled wharf,the unit price of the assembled RC structure decreases by approx.33%,and the total engineering cost can be reduced by about 20%,which leads to significant economic results.
