The stability against overturning of portal water injection sheet piles is the main factor for determining the embedded depth,the construction cost and the overall stability and safety of the portal structure.

This paper gives an exposition on the features,technology,requirement and measures of hydraulic sheeting pile construction combining a case of engineering,through which the feasibility of the construction technique combining hydraulic sheeting with cement grouting applied for wharf engineering on soft foundation is proved.

Based on the characteristics of the large scale group architecture project,several foundation pit support schemes were compared,selected and optimized,and finally the gantry type reinforced cement soil pile support structure was selected.

Through the practice of several works of channel regulation,Dongying Port and the comparison with the traditional technique,the application of hydraulic sliding panel to channel debris dam are mainly introduced.
