It should be understood that the specific embodiments described herein are some embodiments of the present utility model, rather than all embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present utility model.

[0026] Embodiment 1: Please refer to Figures 1-4 , the present utility model provides three technical solutions:

[0027] A subgrade compaction device for municipal road construction includes:

[0028] Inside the housing 1 of the subgrade compaction device, there is a compaction hammer 4. On one side of the housing 1 of the subgrade compaction device, there is a guiding and restraining block 2. Four guiding and restraining grooves 3 are opened on the guiding and restraining block 2. A guiding assembly is arranged inside the guiding and restraining grooves 3. The guiding assembly includes a movable limiting block 5, a fixed connecting block 6, and a guiding connecting rod 7. A guiding connecting rod 7 is arranged inside each guiding and restraining groove 3. A movable limiting block 5 is arranged on one side of each guiding connecting rod 7. A fixed connecting block 6 is arranged on one side of each movable limiting block 5;
