The sections of the first groove and the second groove are both arc-shaped; the quantity of first recess and second recess is 6, 6 first recess equidistant distribution, 6 second recess equidistant distribution. Each support unit has 6 support rings and 6 connecting ribs; the 6 support rings are distributed at equal intervals. The distribution of the regular hexagon shape is set, so that the radial pressure resistance of the cable protection pipe is better. The support ring includes the first cambered plate 3.1 with first recess butt and the second cambered plate 3.2 with the second recess butt, be connected with two planar connecting plates 3.3 between first cambered plate 3.1 and the second cambered plate 3.2.
