When the wall panel 100 drives the first pipe 611 to rotate, the first pipe 611 applies pressure to the first matching hole 410, and since the mortar 614 is poured into the first matching hole 410, the pressure applied to the first matching hole 410 by the first pipe 611 is attenuated, so that the wall panel 100 applies a large force to the first pipe 611, and the first pipe 611 can rotate in the first matching hole 410.

When the shingle 100 applies pressure to the second pipe 621, because the second matching hole 411 is filled with the mortar 614, and the second pipe 621 is provided with the expansion rod 623, the expansion rod 623 is solidified in the mortar 614, so that the stress area at the bottom of the second pipe 621 can be increased, and when the shingle 100 drives the second pipe 621, a large force needs to be overcome. When shingle 100 has the trend that drives second body 621 and rotates, lateral pressure is applyed to second body 621 to second mating holes 411, because second body 621 solidifies together with mortar 614, so lateral pressure that second body 621 applyed to second mating holes 411 is attenuated, and then makes shingle 100 exert great power to second body 621, and second body 621 can rotate in second mating holes 411, and the condition that the reinforced earth retaining wall of final reduction emptys easily takes place.
