Background Art
[0002] In the pump station and sluice project, the working condition of the gate chamber foundation containing a strong permeable soil layer is common. At present, the most commonly used method for treating the foundation of a strong permeable soil layer is mainly the replacement soil cushion method.

The replacement soil cushion method is applicable to the working condition where the poor soil layer is thin. When there is a large thickness of poor soil layer locally, this method consumes a lot and is not suitable for use. Content of the Utility Model
