Research On Key Technologies For L1 Unite Contruction Of Chang River Continuous Girder Bridge

With the rapid rise of the infrastructure industry,the bridge plays an irreplaceable role in real life.Among them,the remarkable characteristic of continuous bridge is that the force transfer is definite,so it is used more and more widely in engineering.In the twenty-first Century of rapid economic development,how to effectively improve transport efficiency and shorten the construction cycle of the bridge is the main problem.The current construction units at home and abroad in the construction of continuous beam bridge,the main selection of cantilever pouring construction methods.In the construction process,the need to ensure that the basic structure of the basic indicators to meet the requirements to ensure that the construction quality of the bridge meet the requirements of all parties,For the L1 Unite(35m+2×55m+35m)of Chang River Continuous Girder Bridge,The design and calculation of full Space Support,temporary consolidation design of 0# block,Hanging basket,and construction quality control are all to be considered seriously.The research work of the paper are as thefollowing:(1)Combining domestic and foreign literatures and related engineering cases,summarize the continuous beam bridge and analyze the current development situation.In addition,the construction technology of the bridge is also described,summed up and analyzed its advantages.(2)According to the characteristics of the support,the design and the calculation of the bowl-button full support for the 0 # block of the continuous girder bridge are carried out.(3)In order to ensure the correct selection of anchor materials,the ability to hold the capsizing and the bearing capacity of the temporary piers,the temporary consolidation of 0# block is analyzed and calculated.(4)According to the characteristics of cantilever,design and inspection of diamond hanging basket is carried out.(5)To study the key technology of continuous beam construction,provide the basis for the construction plan,and put forward the rational continuous beam construction-quality-control plan.
