The retaining wall 5 may be a cantilever retaining wall, an assembled retaining wall, a buttress retaining wall, or a pile plate retaining wall or a rib plate retaining wall; the retaining wall 5 is connected into an integral structure through a concrete cast-in-situ structure, or is pre-poured in a concrete factory and then assembled into the integral structure after being carried to the site.
As shown in fig. 2, at least two anchor plates 2 are movably arranged on the anchor unit, and the anchor plates 2 are connected with the retaining wall 5 through anchor rope bodies 1; the anchoring unit is used to connect the retaining wall 5 with the fill 4 and adjust the interval between the anchor plate 2 and the adjacent anchor plate 2 or retaining wall 5 so as to maintain the retaining wall 5 stable.
2-10 Anchoring units can be arranged on the same section, and the anchoring units are arranged at different heights of the filling 4 at intervals side by side; the number of the anchoring units is correspondingly adjusted according to the height of the filling soil 4 and the height of the retaining wall 5; the retaining wall body is connected with the filler by using the anchoring unit, so that the retaining wall body is kept stable; the tension of the anchor rope body 1 is converted into the compressive stress acting on the anchor plates 2 at the two ends of the anchoring section by the U-shaped anchor bodies and the anchor plates 2 arranged at the two ends of the anchoring section of the anchoring unit, so that the bearing capacity of the prestressed anchor plate 2 is greatly improved. Because the two ends of the anchoring section are subjected to compressive stress on the anchoring plate 2, the bearing capacity of the whole anchoring section and the high compressive strength of the anchoring plate 2 are fully exerted.
Specifically, referring further to fig. 2, the anchor unit comprises at least three anchor plates 2 and at least three anchor cable bodies 1;

It should be noted that two anchor plates 2 are only on the same anchor cable body 1 at the same time, and the anchor plates 2 arranged on two adjacent anchor units are arranged in a staggered manner; because the anchor plates 2 connected to different anchor cable bodies 1 are not identical, the distance between two adjacent anchor plates 2 can be adjusted, the stress concentration at the anchor cable body 1 and the anchor plates 2 caused by only one-time tensioning of the traditional anchor structure is effectively avoided, and the height and the mass of filled soil are increased; the transverse tension generated by newly-added tensioned anchoring units at different heights effectively balances the various pressure generated by newly-added filling soil, avoids the condition that the stress of the anchor cable body 1 is increased beyond a design value caused by the existing method, and effectively ensures engineering safety.
By adopting the method, the problem of stress concentration caused by the existing tensioning method is effectively solved, the stress is respectively shared by all layers, and the stress uniformity of the retaining wall 1 is effectively ensured; by arranging the anchor plates 2 in different numbers in the filling area 4 layer by layer longitudinally and respectively carrying out stress result calculation on each layer, the gap between each layer and the backfill soil at the lower layer is obtained, and finally, the horizontal load caused by filling is evenly shared by each anchor plate 2, and the situation that the stress of the lower anchor unit is increased along with the increase of the filling height is avoided.
In this embodiment, as shown in fig. 2, the other end of the anchor cable body 1 sequentially passes through the through holes 22 formed in the two anchor plates 2, the other end of the anchor cable body 1 is wound on the anchor plate 2 on the side far from the retaining wall 5, and the other end of the anchor cable body 1 is connected to the anchor plate 2 on the side near to the retaining wall 5 through the anchor head 3; the other end of the anchor rope body 1 is connected with one side of the anchor plate 2, which is close to the retaining wall 5, through an anchor head 3.
Wherein, 2-6 anchor plates 2 can be arranged in each anchor unit, and the number of the anchor plates 2 is dependent on the total locking value, the length and the tensioning load of a single anchor cable body 1 of each anchor unit; the anchor plates 2 are all required to be provided with reserved through holes 22, and the through holes 22 are used for penetrating the anchor rope body 1 so that the anchor plates 2 can slide left and right on the anchor rope body 1, the distance between two adjacent anchor plates 2 is adjusted by pulling one end of the anchor rope body 1, and the tensile force of the anchor rope body 1 is converted into compressive stress acting on the anchor plates 2 at two ends of the anchor section, so that the bearing capacity of the prestressed anchor plates 2 is greatly improved.
Referring to fig. 5, when one end of the anchor cable body 1 is tensioned, a "clamping" force is generated on the soil body of the filling 4 between two anchor plates connected with the anchor cable body 1 and between the retaining wall 5 and the anchor plate 2, thereby greatly improving the stress state of the soil body of the filling 4. Meanwhile, due to the arrangement of the anchor plates 2, the stress level of soil body in the front part of the anchor plates 2 is far lower than that of the traditional anchor structure.
It should be noted that 2-6 anchor plates 2 can be arranged in each anchor unit, and the number of the anchor plates 2 depends on the total locking value, the length and the tensioning load of the single anchor cable body 1 of the single anchor unit;
In this embodiment, 3 anchor plates 2 may be disposed in each anchor unit, and 2 anchor plates 2 are movably connected to each anchor cable body 1, where two anchor plates 2 are only on the same anchor cable body 1 at the same time; through pulling one end of the anchor rope body 1 in turn for the interval between anchor plate 2 and adjacent anchor plate 2 or retaining wall 5 on the anchor unit is adjusted, turns into the compressive stress that acts on two adjacent anchor plates 2 or anchor plate 2 and retaining wall 5 with anchor rope body 1 pulling force, thereby improves the bearing capacity of prestressing force anchor plate 2 by a wide margin.
