The retaining wall can form various forms in the telescopic, rotary and moving modes of the triangular superposition module; before an earthquake, the retaining wall resists deformation of the supporting retaining body 6 by virtue of the integral weight of the retaining wall and the support of the stable protective baffle. When an earthquake occurs, the destructive force of the retaining soil body 6 under the action of the earthquake is increased sharply, and the thrust of the retaining soil body 6 to the middle lower part of the retaining wall is the greatest at first; when the retaining wall receives the thrust from the rapid increase of the supporting retaining body 6 in a short time, the laminated layered retaining wall moves to the rear side in sequence from the bottom to the upper part according to the stress effect to be opened to present different forms; the two triangular superposition modules of the retaining wall start the telescopic system due to the thrust of the supporting retaining bodies 6, and then rotate and move towards two sides, so that the work done by the destructive power of the supporting retaining bodies 6 under the action of an earthquake is favorably converted into the kinetic energy increased by the movement of the retaining wall; the movement of the laminated module units of the retaining wall realizes the layer-by-layer unloading of the supporting retaining body 6, resists the suddenly increased soil pressure, obviously reduces the danger of the secondary damage of the supporting retaining body 6, and finally the retaining wall is fixed by the bottom stable fixing system, thereby effectively avoiding the sudden collapse and deformation of the wall body. In addition, as the retaining wall provides an upper branch baffle and a lower branch baffle for the branch retaining body 6, and the upper part is of a superposed module telescopic structure, the upper layer, the lower layer and the front row and the rear row of each layer of the telescopic structure are mutually staggered, the structure is tight, and the overall weight of the wall body is increased; the lower part is embedded firm positioning system, and positioning system divide into three parts, and every firm protection baffle all receives the resistance from the rear side soil body in the removal, has strengthened wall body and has kept off effect and overall stability. The upper telescopic structures all cross the tire, the contact area between the upper telescopic structures and the supporting and retaining bodies 6 can be increased on one side of the clinging slope, the supporting and retaining bodies 6 are effectively prevented from generating huge impact on the retaining wall when being damaged, and the supporting and retaining bodies are sequentially arranged from the bottom edge of the triangular module unit to the top point, so that the effect of restraining soil body layer by layer is achieved. The whole retaining wall body panel is composed of junked tires, huge impact force generated by the retaining wall body 6 is buffered by utilizing the advantage of large damping of the junked tires, energy generated by movement of the retaining soil body 6 under the action of an earthquake is resisted, the energy is gradually dissipated, the retaining wall body 6 finally reaches a stable state, and the integral earthquake resistance of the retaining wall is enhanced. After the earthquake is finished, the left overlapping module system top module 112, the right overlapping module system top module 122, the left overlapping module system top module 112 and the right overlapping module system top module 122 can be retracted to an initial state by external force after the disaster of the supporting and retaining body 6 is repaired.
