The invention discloses a detachable geocell. The detachable geocell comprises a connecting base and a basal cell. The basal cell comprises a fixing base. Clamping grooves are evenly distributed in the peripheral sides of the fixing base. A mounting groove is formed in the surface of the other end of the fixing base. The peripheral side of the mounting groove is connected with the clamping grooves in a cut-through mode. Connecting plates are mounted in the clamping grooves. Clamping heads are arranged at one ends of the connecting plates, mounted in the clamping grooves and placed between a pressure pad and a bottom cap. Three mounting columns are arranged on each connecting plate in the direction from the clamping head to the other end of the connecting plate at equal intervals. A columnar groove is formed in the surface of one end of each mounting column, and two connecting grooves are symmetrically formed in the peripheral side of each mounting column. Four connecting grooves are evenly distributed in the peripheral side of the connecting base. The connecting base is fixedly connected with the basal cell through the connecting grooves. Through the array type composite structure, the geocell is divided into a plurality of blocks with the same compartment area, so that pressure of fillers in grids to the inner walls of the geocell is uniform, the mounting service life of the geocell is greatly prolonged, and the mounting process of a whole project is ensured.
