Study on Slurry Leakage Treatment Technology for Water Stop Ring of the Outlet of Pipe Jacking in High Water Pressure Formation
In the long-distance pipe jacking construction process,the problem of slurry leakage and water leakage may occur in the starting outlet due to the over-high groundwater pressure,the deformation of steel ring under pressure,and failure of the sealing rubber under the long-term tensile stress,resulting in a sudden increase in the jacking force.As the jacking distance continues to increase,there will be a serious consequence of immobil-ity.In order to solve the technical problem of slurry leakage of the water stop ring of the of the outlet of pipe jacking in high water pressure formation,the paper analyzes the causes of slurry leakage based on the example of the Diversion Project from Inner Mongolia to Liaoning,and introduces a treatment method and key technolo-gy for slurry leakage of water stop ring at the starting of pipe jacking under the condition of high water pres-sure formation,which provides reference for similar projects.
