AI Technical Summary
Existing inclinometer tubes used for foundation pit monitoring are prone to getting soil inside during use, making it difficult to insert the inclinometer further, and the soil residue inside is difficult to clean completely, affecting the accuracy of the measurement.
An anti-clogging device was designed, comprising a mounting flange, a threaded rod, an anti-clogging plate, a movable shaft, a fixed rod, a telescopic block, a scraper, and a spring. By turning the handle, the threaded rod is rotated, and the anti-clogging plate moves up and down inside the inclinometer tube, pushing the movable shaft and the scraper to rotate on the inner wall. The scraper cleans the soil and collects it on the anti-clogging plate.
This effectively prevents soil from entering the inclinometer tube, ensuring that the inclinometer can be inserted smoothly, and thoroughly cleans the soil residue inside, thus improving measurement accuracy.
