| description | The invention provides a rainfall seepage-proofing structure for a cut/fill square section from a road side ditch to a slope toe area. The seepage-proofing structure comprises a vertical seepage-proofing ash soil layer, a geomembrane, a soil filling layer and a vegetation layer which are sequentially arranged above in-situ soil of a slope toe area. A plurality of adjacently distributed C-shaped precast concrete blocks are longitudinally arranged on the side, close to a side ditch, of the slope toe area, the top faces of the C-shaped precast concrete blocks are higher than the top face of the vegetation layer, and the C-shaped precast concrete blocks are filled with precast pervious concrete. The rainfall seepage-proofing structure is used for preventing roadbed soil softening, further induced settlement, differential settlement and cracks of a road surface, inclination and cracking of a road shoulder retaining wall of a cut/fill square section and other diseases caused by rainfall.
