Prestressed gravel anchoring pile and landslide control construction method thereof
The invention discloses a prestressed gravel anchoring pile and a landslide control construction method thereof. The prestressed gravel anchoring pile is of a columnar structure and comprises an anchor head disc, a gravel water collecting and discharging section, a bottom disc, a gravel cushion layer, a porous shock tube and a plurality of prestressed anchor rods, the porous shock tube is penetratingly arranged between the anchor head disc and the gravel water collecting and discharging section, the top of the porous shock tube extends out of an upper plane of the anchor head disc, the prestressed anchor rods penetrate the gravel water collecting and discharging section, two ends of the prestressed anchor rods are fixed on the anchor head disc and the bottom disc respectively, and a water draining pipe is arranged on the bottom disc and communicates the gravel water collecting and discharging section with the gravel cushion layer. The landslide control construction method mainly includes the steps of excavating a hole for the gravel anchoring pile, laying the bottom gravel cushion layer, constructing the reinforced concrete bottom disc, embedding the anchor rods in the bottom disc, filling and building the gravel water collecting and discharging section, stretching the anchor head disc. By the structure and the method, water level of underground water in a landslide body is lowered effectively, water content inside the landslide body is reduced, and anti-shearing performance of a sliding face is improved, so that stability of a landslide is improved.
