[0004] Regarding the above-mentioned related technologies, when in use, the values ​​of the two measurements before and after are obtained through the correspondence between the sliding bar and the scale on the measuring rod, and then the foundation settlement result is obtained by subtracting it. However, the foundation may settle unevenly while settling, which may cause the measuring rod to tilt. At this time, the scale on the measuring rod pointed to by the sliding bar is no longer accurate, which affects the accuracy of the foundation settlement measurement. Summary of the invention

[0043] The implementation principle of a construction foundation settlement measurement device according to an embodiment of the present application is as follows: a receiving ball 1 and a comparison rod 4 are respectively set at a measuring point and a reference point. After waiting for a period of time, if the measuring point settles evenly, the absolute elevation of the receiving ball 1 will drop.

At this time, a visible laser is emitted by a laser transmitter 5 and irradiated onto the observation rod 3. By observing and recording the readings on the observation rod 3, the average value of the readings is taken after repeated multiple times to obtain the foundation settlement value of the measuring point. If the measuring point settles unevenly, the receiving ball cavity will deflect. However, even if the spherical liquid cavity in the receiving ball 1 deflects, the liquid level height therein remains unchanged. The degree is still horizontal, so that the observation rod 3 always remains in a vertical state.
