This utility model discloses an embedded lightweight soil retaining panel structure, installed on a base with mounting grooves. The lightweight soil retaining panel structure includes precast panels and mounting beams arranged in an H-shape at intervals. The top of each precast panel has a groove, and the bottom of the precast panel has a retaining edge that matches the groove. The mounting beams are spaced apart on the base, and the retaining edges of the precast panels at the bottom mate with the mounting grooves. Both ends of the precast panels are engaged with the mounting beams, and the upper precast panels are interconnected through the retaining edges and grooves. This embedded lightweight soil retaining panel structure, with its H-shaped mounting grooves on the base and mounting beams on both sides, fixes the mounting beams to the base, thus limiting the
lateral movement of the precast panels. Simultaneously, the retaining edges and grooves on the precast panels allow for rapid splicing of the precast panels.
