The invention discloses an anti-swirl composite material wall feed-through sleeve flange piece which comprises a flange body mounted on a wall body. A plurality of waterproof rings are arranged on the flange body and are used for mounting a wall feed-through sleeve. The flange body is provided with a plurality of mounting holes used for mounting the waterproof rings. Buffer holes are formed in the four side walls of the flange body correspondingly and are internally provided with buffer springs. One end of each buffer spring is connected with a mounting block capable of stretching into the corresponding buffer hole. Mounting grooves matched with the mounting blocks are formed in the positions, corresponding to the mounting blocks, in the wall body. The diameter of a hole, allowing the wall feed-through sleeve to be inserted into, in the wall body is greater than that of the wall feed-through sleeve. The anti-swirl composite material wall feed-through sleeve flange piece provided by the invention is resistant to fragmentation.
