PURPOSE: A direction adjustment tube assembly for drainage maintenance is provided to be adjusted in posture according to the onsite gradient change of a longitudinal drain tube in order to promptly correspond to the gradient. CONSTITUTION: A direction adjustment tube assembly for drainage maintenance comprises a connection bent tube (20A) and a direction adjustment tube (30). The connection bent tube is formed with a circular protrusion (202) with an inlet (202a) towards a collecting channel. The direction adjustment tube includes a pair of partitioned tube bodies which is formed with a bolting wing plate on each partitioned surface. The circular protrusion (302) of the direction adjustment tube partially covers the circular protrusion of the connection bent tube. The direction adjustment tube is able to rotate for 360 degrees and to adjust the inclination. |
