CUTOFF DEVICE FOR INTERCEPTING SEWER AND CUTOFF METHOD USING THAT

CHO SUNG HYUN

The present invention relates to a water cutoff device for an intercepting sewer and a water cutoff method using the same, capable of cutting off sewage in a state in which an operator does not come into an intercepting sewer, preventing the water cutoff device from moving by the speed of the sewage, and preventing loss of sewage to a gap between the intercepting sewer and the water cutoff device after a water cutoff operation is completed. The water cutoff device for an intercepting sewer comprises: a support inserted through a manhole part formed to connect the intercepting sewer and the ground; a panel main body installed in the support and inserted into the intercepting sewer to cut off a flow of sewage; a plurality of extending panels installed in the panel main body such that the plurality of extending panels protrude or retract; a driving unit making the extending panel protrude from the panel body such that a space between the intercepting sewer and the panel main body is finished; and a fixating unit fixating the support or the panel main body to the manhole part to prevent the support or the panel main body from being moved by the speed of the sewage in a state in which the panel main body is inserted into the intercepting sewer.

본 발명은, 차집 관거와 지면을 연결하여 통하도록 형성되는 맨홀부를 통해 삽입되는 지지대; 상기 지지대에 설치되고 차집 관건 내부로 삽입되어 하수의 흐름을 차단하는 패널본체; 상기 패널본체에 출몰 가능하게 설치되는 복수 개의 연장패널; 차집 관거와 상기 패널본체 사이의 간격이 마감되도록 상기 연장패널을 상기 패널본체로부터 돌출시키는 구동부; 및 상기 패널본체를 차집 관거 내부로 삽입한 상태에서 하수의 유속에 의해 상기 지지대 또는 상기 패널본체가 유동되는 것을 방지하도록 상기 지지대 또는 상기 패널본체를 맨홀부에 고정시키는 고정부를 포함하는 것을 특징으로 한다.
