The utility model discloses a settlement observation device, which comprises an embedded part and an observation head, wherein the embedded part is embedded in a wall. An internal thread is formed at a first end of the embedded part, and an external thread is formed at a first end of the observation head matched with the first end of the embedded part. When settlement observation is carried out, the embedded part is in threaded connection with the observation head through the first end of the embedded part and the first end of the observation head. Possibility of damage to the settlement observation device caused by external factors is reduced, and identification of an observation point is more obvious. The settlement observation device has the advantages of being stable, difficult to drop and damage, reasonable in structure, long in service life and obvious in identification.
