<p><P>PROBLEM TO BE SOLVED: To provide an intratubular turbidity removing device which is temporarily attached to a branch pipe or in the vicinity of a construction objective water service pipe, and can discharge turbidity flowing in a drain pipe without causing water failure of the water service pipe. <P>SOLUTION: According to the structure of the intratubular turbidity removing device, a pipe unit (3a) is detachably arranged in a branch pipe (2a) which is set in the water service pipe (1), and a suction pipe (6) having a suction nozzle (7) at a front end thereof, is hung in the branch pipe (2a). Then a rear end of the suction pipe is engaged with a suction port (4a) opened to the pipe unit (3a), and the front end of the suction nozzle (7) is opened to a pipe bottom upstream side (A), followed by connecting a circulation pipe (8) to a connection port (10) of the suction pipe (6) and a discharge port (5a) of the pipe unit (3a). Thus separated water from which turbidity is removed is returned to the water service pipe (1), and therefore stable supply of service water etc. is achieved without occurrence of a contingency such as water failure. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
