The invention belongs to the technical field of overpressure chambers, and particularly discloses a portable self-made overpressure chamber. The portable self-made overpressure chamber comprises a platform body, an overpressure chamber body, door frame angle steel and a door leaf. According to the portable self-made overpressure chamber, putty is arranged between the platform body and the door frame angle steel, the outer side of the putty is brushed with two layers of paint, the sealing performance between the platform body and the door frame angle steel is improved, sealing rubber pads are arranged at a pressure measuring opening and an air inlet, a sealing strip is arranged between the door frame angle steel and the door leaf, the sealing performance of the overpressure chamber is improved, according to a large number of on-site practices, the pressure of the sealed overpressure chamber body can be maintained to be 50 Pa within 10 min, the subsequent test requirement can be completely met, and compared wit
