Design and Model Test of Shaft Lining Compressible Connector in Deep Hydrophobic Alluvium

Because of the hydrophobic consolidation settlement, there is a large axial additional force between the deep alluvium and the shaft lining, which is the major cause for damage of the shaft. The article proposes a new type compressible connector in hydrophobic shaft lining. The model test indicates that under the axial additional force, the connector has good axial compressed deformation features, lateral compressive resistance capacity, and reliable water proof and leak proof ability.
