Referring to fig. 1-3, the slope protection system for thicker base layer and sprayed concrete of the present utility model includes an overhead array 1 formed by supporting, covering and supporting a protection net of a framework, geotextile or steel wire ropes, wherein the overhead array 1 is provided with a suspension type anchor rod 2 array formed by a plurality of anchor rods 2, and the anchor rods 2 are anchored into an original slope 3.
The middle suspension position of the overhead array 1 formed by the protective net, geotextile and steel wire ropes of the supporting, covering and supporting framework has a suspension effect.
The suspension type anchor rod 2 array is arranged in a quincuncial mode.
The gap between the anchor rod 2 and the original slope surface 3 (the original slope surface in the embodiment comprises a soil layer and a rock stratum), and the anchor rod is anchored into the rock stratum and is filled with grout.
The bottom of the anchor rod 2 is anchored into the original slope surface 3, the top is provided with a clamping system consisting of an upper fastening base plate 4 and a lower fastening base plate 5, the overhead array 1 is clamped in the clamping system, and the anchor rod 2 is screwed with an adjusting bolt 6 to fasten the upper fastening base plate 4 and the lower fastening base plate 5.
Construction installation sequence and method
(1) Clearing the slope: regulating the boundary of the terrain, removing the floating earth and pumice, backfilling pits when needed, and cutting down trees without special reserved value to the root;
(2) Paying off the anchor rod 2 hole sites by taking the slope feet as datum lines, wherein the anchor rod 2 hole sites are preferably arranged at natural pits, but the distance is not more than 10% of the design value; hole sites are arranged at partial extreme protruding positions;
(3) Drilling the anchor rod 2 holes according to the design depth from top to bottom, clearing the holes, constructing the hole diameter according to the design requirement, and enabling the anchor rod 2 to be vertical to the slope surface as much as possible on the premise of ensuring that the included angle between the anchor rod 2 and the horizontal plane is not smaller than 15 degrees; when the slope entering angle of the adjacent anchor rods 2 is overlarge, the angle is adjusted in a homeotropic manner, so that the included angle of the backing plates of the adjacent anchor rods 2 is smaller than 30 degrees as far as possible; when the local hole site can not be formed due to loose or broken stratum, a concrete foundation can be adopted to replace a rock-soil section which can not be formed;
(4) Installing the anchor rod 2 and grouting, cleaning the head of the anchor rod 2 and ensuring that the exposed length is enough; the slurry should adopt cement mortar or cement paste with the strength grade not lower than M20, so as to ensure full slurry, and the slurry is injected for maintenance for not less than three days before the next working procedure is carried out;
(5) According to the thickness requirements of the spray seeding and the concrete spraying 7 and the condition of the slope surface, the position of the bolt 6 at the exposed free end of the anchor rod 2 is adjusted so as to form a certain interval with the slope surface. Then placing a lower fastening backing plate 5 as a supporting plate of a protective net, a geogrid, steel bars and steel wire ropes; the anchor rods 2 are arranged in a plum blossom shape;
