description Disclosed is a waterproof pressure test device for a driving unit seal for a shield TBM, which is able to test the waterproofing performance and the durability of the driving unit seal affected by a soil pressure and a water pressure on the shield TBM in a work environment where an actual tunnel is being constructed. The waterproof pressure test device comprises: an outer housing forming a pressure chamber where a soil pressure and a water pressure work inside; an inner housing rotatably installed in the outer housing; a seal assembly installed in the inner housing; a ring structure installed in the outer housing and forming a back pressure chamber coming in close contact with the seal assembly and being capable of communicating with the pressure chamber; and a driving unit providing rotation power to the inner housing. 본 발명은 실제 터널을 시공하는 작업환경에서 쉴드TBM 장비가 받게 되는 토압과 수압에 의해 구동부 씰에 미치는 방수성능과 내구성능을 실제와 동일하게 모사된 환경에서 시험할 수 있는 쉴드TBM 장비용 구동부 씰의 방수압 시험장치를 개시한다. 전술한 방수압 시험장치는 내부에 토압과 수압이 작용하는 압력실을 형성하는 외부하우징, 외부하우징의 내부에 대해 회전 가능하게 설치되는 내부하우징, 내부하우징에 설치되는 씰조립체, 외부하우징에 설치되어 씰조립체와 긴밀하게 접촉하고 압력실과 교통 가능한 배압실을 형성하는 링구조물, 및 내부하우징에 대해 회전력을 제공하는 구동부를 포함한다.
