The invention provides a buried enhanced and modified polypropylene ripple cable sleeve. The buried enhanced and modified polypropylene ripple cable sleeve comprises a single-wall ripple pipe wall extending along the length direction of the sleeve, a buckling pipe fitting, and a sealing ring. The outer wall of the single-wall ripple pipe wall is provided with a plurality of annular bulges, the cross section of each annular bulge is shaped like an isosceles trapezoid, and the annular bulges adopt arc transition. The inner wall of the sealing ring sleeves one end of the outer wall of the single-wall ripple pipe wall. The inner wall of the buckling pipe fitting sleeves the outer wall of the sealing ring. The buckling pipe fitting comprises a first pipe fitting and a second pipe fitting. Arc side edges of the first and second pipe fittings are provided with stoppers. One end of the first pipe fitting is hinged to one end of the second pipe fitting, and the other end of the first pipe fitting is in buckled connection with the other end of the second pipe fitting. The buried enhanced and modified polypropylene ripple cable sleeve is a single-wall ripple pipe of a specific waveform, adopts the special anti-off buckling pipe fitting for connection, and is advantaged by being high in annular rigidity and low-temperature punching intensity, small in inner wall friction coefficient, light in weight, excellent in performances of environmental protection, high-temperature resistance, aging resistance, wear resistance, water resistance and sealing, capable of being coiled and piled, and convenient in construction.
