Description

Technical Field

[0001] The utility model relates to the field of pier settlement measurement, and specifically relates to a pier settlement measurement device. Background Technique

[0002] At present, under the action of building loads, the vertical deformation or settlement of foundation soil caused by compression. Uniform settlement generally has less harm to buildings, but when it is too large, it will also reduce the elevation of the building and affect its use; non-uniform settlement is more harmful to buildings, which will cause additional stress in the building and lead to cracks, and even local component fractures, endangering the safety of the building. As the bearing structure of the bridge, the bridge pier must have sufficient strength and stability. However, with the increase of traffic flow, load and vehicle speed, it has a great impact on the settlement value of the bridge pier. Once the settlement value exceeds the pre-controlled range, it will cause cracks in the bridge and even lead to bridge collapse. Therefore, it is necessary to measure the settlement of the pier. The existing measurement method usually draws a line horizontal to the ground on the bridge pier, and then measures the distance between the ground and the drawn line with a steel tape after a period of time, so as to know the settlement degree of the bridge. The measurement data is prone to deviation, affecting the data accuracy, and there are potential safety hazards, which brings certain adverse effects to the use process. For this reason, we propose a pier settlement measurement device. Content of the Utility Model
