A filter screen assembly 6 for blocking the drainage pipe 2 is fixedly installed on the reinforcement frame 5. A secondary filter material layer 7 surrounding the main filter material layer 4 is also provided on the block plate 3. By setting the drainage pipe 2 in the retaining wall 1, it is ensured that the drainage operation can be stable during use. At the same time, by fixing the block plate 3 on one side of the retaining wall 1, it is easy to install the main filter layer 4 through the block plate 3, so that the main filter layer 4 can be stably set at the head of the drainage pipe 2 for auxiliary filtering. At the same time, by designing the main filter layer 4 into a structure that matches the filter shell 41 and the gravel part 42, it is easy to use by first installing the filter shell 41 at the head of the drainage pipe 2. After the filter shell 41 is fixedly installed, gravel can be piled up to form the gravel part 42. At the same time, by fixing the filter shell 41 on the filter shell 41, the filter shell 41 can be fixedly installed on the filter shell 41. The reinforcement frame 5 further increases the strength of the filter housing 41, and at the same time ensures that the filter assembly 6 can be installed through the reinforcement frame 5. After the reinforcement frame 5 is fixedly installed in the filter housing 41, the filter assembly 6 can be fixedly installed on the head of the drain pipe 2. In this way, the drain pipe 2 can be shielded by the filter assembly 6, which can effectively prevent gravel from flowing into the drain pipe 2. After the construction of the main filter layer 4 is completed, a secondary filter layer 7 can be set on its outside. The secondary filter layer 7 can be piled with coarse sand, and then the main filter layer 4 can be surrounded by the secondary filter layer 7 to achieve double filtration of the drainage. The retaining wall 1 includes a base 11 and a vertical wall panel 12.

The filter plate 63 is fixedly mounted in the middle of the mesh frame 61. The structural arrangement of the filter assembly 6 ensures that the mesh frame 61 can be stably mounted on the oblique blocking frame 52 via the connecting rod 62 when in use. At the same time, by fixing the filter plate 63 in the mesh frame 61, the drain pipe 2 can be shielded by the filter plate 63.

[0035] The implementation principle of a drainage pipe filter material backfill device in an embodiment of the present application is as follows: during actual construction, the reinforcement frame 5 is first installed in the filter material shell 41, and then the two are fixed to each other by bolts. Then the filter material shell 41 can be installed on the block plate 3, and the outer discharge pipe 414 on the filter material shell 41 is inserted into the drainage pipe 2 of the retaining wall 1 in sequence. After the filter material shell 41 is installed, the gravel part 42 can be piled in the filter material shell 41, and finally the secondary filter material layer 7 can be piled up and surrounded on the outer surface of the main filter material layer 4. In this way, the filling operation can be carried out. During the filling and compaction process, the main filter material layer 4 can be stably supported by the block plate 3, which can effectively avoid downward movement.
