Mixed fiber recycled concrete water permeable brick with mortise and tenon joint structure

The invention relates to a mixed fiber recycled concrete water permeable brick with a mortise and tenon joint structure. The mixed fiber recycled concrete water permeable brick is characterized by comprising a water permeable brick body, the water permeable brick body is of a cuboid structure, a tenon is arranged on the front end face of the water permeable brick body in the length direction, thetenon is of a cross block structure, and the tenon and the water permeable brick body are integrally formed; a cross-groove-shaped mortise which is in mortise joint with adjacent tenon is formed in the rear end face of the water permeable brick body from back to front; a connecting protruding block protrudes out of the side face, adjacent to the tenon, of the water permeable brick body; the connecting protruding block and the water permeable brick body are integrally formed; and a rectangular groove matched with the connecting protruding block is inwards formed in the corresponding position ofthe opposite side of the
