Description

Technical Field

[0001] The utility model belongs to the technical field of settlement detection, and in particular relates to a relative settlement detection device. Background Art

[0002] The foundation of a bridge is under load, so each layer of soil within a certain depth will undergo varying degrees of compression and deformation, causing the foundation to settle and, in turn, causing small vertical, horizontal, and angular displacements of the bridge piers. The vertical displacement of the pier is also called pier settlement.

[0003] Pier settlement varies depending on the degree and characteristics of foundation settlement. Some are normal, while others indicate abnormalities or damage. Bridge foundations under different conditions exhibit significant variations in settlement values, speed, and development trends. Good foundations can experience final settlement values ​​of only a few millimeters or less, while poor foundations can reach tens of centimeters or even more than a meter.

[0004] The amount of settlement is directly proportional to the external load and inversely proportional to the time factor. That is, the heavier the unit load, the greater the settlement; the longer the time interval, the settlement gradually decreases and eventually disappears.

[0005] The problem with the existing technology is that it usually uses dedicated level equipment for settlement detection, which has certain requirements on the equipment placement site and employee professionalism, high investment cost, complex operation and inconvenient detection.
