High Pile Wharf Steel Sleeve Grouting Repair Technology Research And Application In Practical Engineering

Some of the new terminal is put into use,the lack of maintenance during operation,and use some terminal even more than the design requirements of life,the pile wharf damaged,some parts damaged,in the safe use,can not be effectively guaranteed bearing.At the dock during the operation,in the process of loading and unloading cargo container cargo terminal,its components in various complex loads,because beyond the normal range,the bearing capacity of long-term fatigue,accidental collision caused by pile wharf whole or local damage,thus affecting the durability and bearing capacity of wharf building structure.When the pile foundation is immersed in seawater for a long time,it will cause cracking and corrosion of reinforced concrete members.Based on the example of the construction of the Zhejiang container wharf pile foundation restoration project,through the collection of relevant data and information,on-site practice,school teacher guidance,to analyze the key technology of steel sleeve grouting of pile wharf repair engineering in repair.First of all,according to the engineering data,the wharf structure adopts the high pile beam slab structure,and the location of the cracks in the whole pier and the depth and size of the cracks are clearly defined.Secondly,according to the characteristics of the repair project and the design requirements,the grouting repair plan for the steel sleeve is selected.On this basis,the preparation of specific construction plans and specific repair construction organization.Finally,the measures for ensuring the safe production during the construction of the high piled wharf repair project are worked out.In the guarantee period,does not affect the normal use of the pier.The research results of this paper have important practical value and wide popularization significance to the construction of grouting repair project of similar high piled wharf.
