Structure and method for processing black cotton soil embankment with impervious geotextiles
The invention provides a structure and a method for processing a black cotton soil embankment with impervious geotextiles. The embankment structure comprises a geogrid gravelly soil base course, impervious geotextile edging and interlayer seepage-proofing layers, a black cotton soil fill stratum and a non-expansive clay top seal layer. The method comprises the following steps: (1) clearing a foundation; (2) setting out; (3) paving three layers of geogrid gravelly soil with the total thickness being 50cm; (4) spreading the impervious geotextiles on two sides of the road foundation, lapping the impervious geotextiles with filled soil by 250cm, turning up the impervious geotextiles on the slope of the road foundation, lapping the impervious geotextiles on the two sides in the middle of an embankment by 100cm after turning up, and bonding by using emulsified asphalt, wherein the lapping width of the adjacent impervious geotextiles is100cm and the impervious geotextiles are bonded by virtue of the emulsified asphalt; (5) spreading the soil and carrying out rolling construction; and (6) filling and rolling the top seal layer. The structure and the method disclosed by the invention are conducive to the stabilization of the embankment and are capable of preventing the embankment from deformation.
