When encountering the tie bolts of the retaining wall formwork, control the magnetic suction controller to disconnect the connecting plates at the near tie bolt, the middle position, and the far tie bolt in sequence according to the direction of movement, so that the tie bolt passes between the magnetic suction plate and the movable plate of the connecting plate. S40. When the concrete poured inside the retaining wall formwork reaches the layer thickness, the stone transport vehicle is brought close to the chute, and the stones are manually placed into the chute and then into the concrete. S50. Move the stone transport vehicle, sliding platform and support platform in the opposite direction to the direction of concrete pouring to ensure that the stone is evenly inserted into the concrete in the retaining wall formwork. S60. When encountering the tie bolts of the retaining wall formwork, control the magnetic suction controller to disconnect the connecting plates at the near tie bolt, the middle position, and the far tie bolt in sequence according to the direction of movement, so that the tie bolt passes between the magnetic suction plate and the movable plate of the connecting plate.

8. A method for pouring a rubble concrete retaining wall, using the rubble concrete retaining wall pouring and rubble throwing device as described in claim 3, characterized in that, Specifically, the following steps are included: S100, formwork erection, pouring and curing of retaining wall foundation; S200, backfilling earthwork, supporting retaining wall formwork based on retaining wall foundation; S300, construct sliding platform and support platform, install chute and pouring pipe; S400, using a rubble concrete retaining wall concrete pouring and rubble throwing device to pour rubble concrete retaining walls in layers. After the S500 rubble concrete retaining wall is poured, it should be cured until the concrete strength reaches 75% and then the retaining wall formwork should be removed.

9. A method for pouring a rubble concrete retaining wall according to claim 8, characterized in that, The operation steps of step S400 are as follows: S1. Adjust the height of the pouring pipe so that the position of the connecting section movable piece is aligned with the tie bolt inside the retaining wall formwork; S2. After the concrete truck arrives with the materials, it aligns the hopper with the chute to pour the concrete. The concrete enters the pouring pipe through the chute and then reaches the retaining wall formwork. S3. When a certain thickness is poured at a certain position inside the retaining wall formwork, the concrete truck, sliding platform and supporting platform move simultaneously along the length of the retaining wall formwork. During the movement, the sliding platform and supporting platform keep in sync, and the hopper of the concrete truck is always aligned with the chute. S4. When encountering the tie bolts of the retaining wall formwork, control the magnetic suction controller to disconnect the connecting plates at the near tie bolt, the middle position, and the far tie bolt in sequence according to the direction of movement, so that the tie bolt passes between the magnetic suction plate and the movable plate of the connecting plate. S5. When the concrete poured inside the retaining wall formwork reaches the layer thickness, the stone transport vehicle is brought close to the chute, and the stones are manually placed into the chute and then into the concrete. S6. Move the rubble transport vehicle, sliding platform, and supporting platform in the opposite direction to the direction of concrete pouring to ensure that the rubble is evenly inserted into the concrete within the retaining wall formwork. S7. When encountering the tie bolts of the retaining wall formwork, control the magnetic suction controller to disconnect the connecting plates at the near tie bolt, the middle position, and the far tie bolt in sequence according to the direction of movement, so that the tie bolt passes between the magnetic suction plate and the movable plate of the connecting plate. S8. After the first layer of concrete and rubble masonry is completed, if it is not necessary to raise the height of the pouring pipe, repeat steps S2-S7 to construct the next layer of concrete and rubble masonry. If it is necessary to raise the height of the pouring pipe, raise the height of the pouring pipe first, and then repeat steps S2-S7 to construct the next layer of concrete and rubble masonry. After raising the height of the pouring pipe, the pouring pipe located in the retaining wall formwork must still ensure that the position of the movable piece of the connecting section is aligned with the tie bolt inside the retaining wall formwork.
