Background
The reinforced earth is an integral composite structure formed by three parts of filling earth, strip-shaped lacing wires with certain weight arranged in the filling earth and an upright wall panel. The internal force of the wall surface soil pressure, the tension of the tie bars, the friction between the filler and the tie bars and the like are mutually acted in the structure, the forces are balanced, the internal stability of the composite structure is ensured, and the reinforced structure can resist the lateral pressure generated by filling soil behind the tail part of the bar, namely the external stability of the reinforced retaining wall is ensured, so that the whole composite structure is stable. The common forms of the reinforced earth retaining structure include a strip type and a wrapping type. The strip structure is generally that high-strength and high-modulus reinforced strips are arranged in the filled soil at a certain interval, one end of each strip is connected with a panel on the side of the structure, and the other end of each strip is embedded in the filled soil; the wrapped structure is formed by fully paving a flat silk woven geotextile in soil, filling and compacting soil on each layer of laid fabric, rolling back the fabric at the outer end part to a certain length, then laying another layer of fabric on the fabric, wherein the thickness of the filled soil on each layer is 0.3-0.5 m, filling and compacting the soil, and increasing the height layer by layer. However, under the condition of heavy rainfall, a layer of capillary bubble barrier is often formed on the surface of the inner fabric layer of the reinforced soil, so that rainwater cannot seep, the pore water pressure of the slope is increased, and the slope is unstable or collapsed. In order to solve the problem, the invention provides a breathable sap coating composite material for preventing slope infiltration and a manufacturing method thereof, which can remarkably reduce or eliminate the accumulation of infiltration rainwater in the reinforced soil side slope embankment and avoid soil body damage by flowing along the runoff of the slope.
