Example 1

the lattice beam 200 may be a grouted block stone lattice, a cast-in-place reinforced concrete lattice or a pre-stressed concrete lattice, and is provided in the form of a square, diamond, herringbone or arc structure;

the lattice beam 200 can distribute the remaining slip force or soil pressure and rock pressure of the slope body to the anchoring members 300 at the lattice beam joints and then transmit the slip force or soil pressure and rock pressure to the stable foundation layer 102 through the anchoring members 300, so that the deformed slope 100 is in a stable state under the anchoring force provided by the anchoring members 300;

however, the anchor 300 is only arranged at the joint of the adjacent sash of the lattice beam 200, so that the acting force that the anchor needs to bear is large, and the protection effect on the deformed slope 100 is not durable enough, so the application arranges the lattice beam 200 at the deformed position of the slope sliding layer 101 in a staggered and overlapped manner, that is, the adjacent sash of the lattice beam 200 is arranged at the deformed position of the slope sliding layer 101 in a staggered and overlapped manner, as shown in fig. 2, but fig. 2 only represents one structural unit of the lattice beam 200, and does not represent the whole structure of the lattice beam 200;

the anchoring parts 300 sequentially penetrate through the lattice beam 200 and the side slope sliding layer 101 and extend into the stable foundation layer 102 for anchoring connection, and the anchoring parts 300 positioned at the staggered overlapping part of the lattice beam 200 are arranged around the horn shape, namely the anchoring parts 300 are respectively arranged at the joint point of the adjacent lattices of the lattice beam 200, on the lattices of the lattice beam 200 and at the staggered overlapping part of the adjacent lattices of the lattice beam 200;

the anchoring member 300 is an anchor rod or an anchor cable;

adjacent lattices of the lattice beams 200 are arranged in a staggered and overlapped mode at the deformed position of the slope sliding layer 101, and a plurality of anchoring pieces 300 are arranged in a staggered, overlapped and surrounded mode, so that residual acting forces such as sliding force, soil pressure and the like at the deformed slope 100 can be uniformly dispersed to the anchoring pieces 300, the acting forces are transmitted to a plurality of action points of the stable foundation layer 102, the residual deformation acting forces at the deformed position are dispersed, the bearing force of each anchoring piece 300 action point on the stable foundation layer 102 is reduced, the deformation range is effectively prevented from being further expanded, and the deformed slope is well protected;

further, in order to prevent the soil body in the middle of the lattice beam 200 from slipping off, a reinforcing mesh, an iron wire mesh or a geogrid is arranged in the middle of the lattice beam 200;

in order to strengthen the stability of the whole supporting structure, reinforcing steel bars are also arranged in the lattice girders 200.

the anchoring structure further includes a retaining wall 400 and a drainage ditch 500, and the retaining wall 400 is set at the lower side of the deformed slope 100, as shown in fig. 3;

the retaining wall 400 is formed by pouring reinforced concrete, and the retaining wall 400 can bear the pressure of the slope soil body and further prevent the deformed slope soil body from sliding downwards;
