[0030] Working principle: The anti-seepage reinforced embankment structure is suitable for embankment reinforcement projects with seepage risks. Before construction, the cross section is excavated to the design elevation, and then the steel sheet pile 4 is driven using a press until the multiple steel sheet piles 4 are driven into the ground and form a continuous steel sheet wall. At this time, the multiple steel sheet piles 4 serve as the vertical anti-seepage body of the embankment foundation. Then, holes are drilled at the top of the steel sheet pile 4 and steel bars are arranged, the steel bars extending on both sides are used to pour concrete to form a ground beam 5, and then clay 9 is filled between the ground beam 5 and the retaining wall 3 for backfilling. Then, the reinforced concrete toe 6 of the horizontal section is poured on the upper surface of the ground beam 5, the reinforced concrete facing 7 is poured on the slope section of the embankment body 1 and the outer side of the original retaining wall 3, the copper sheet 10 is arranged between the reinforced concrete facing 7 and the reinforced concrete toe 6, and finally the reinforced concrete flood wall 8 is poured on the top, and stone-like texture embossing is arranged on the outer surfaces of the reinforced concrete facing 7 and the reinforced concrete flood wall 8, thereby completing the reinforcement construction of the embankment.

The steel sheet pile 4 serves as a vertical anti-seepage body to reduce the underground water pressure in the embankment foundation, and the reinforced concrete facing 7 serves as an anti-seepage layer to reduce the seepage pressure in the embankment body. The reinforced concrete toe 6 and the ground beam 5 integrally combine the steel sheet pile 4 and the reinforced concrete facing 7, thereby improving the overall stability of the embankment cross section.
