Technical Field
[0001] The utility model relates to the technical field of subgrade monitoring, and particularly relates to a track line subgrade settlement detection recorder. Background Technique
[0002] Subgrade settlement is also known as subgrade subsidence or ground subsidence. It is a local downward movement in which the elevation of the earth's surface decreases due to the consolidation and compression of loose underground strata under the influence of human engineering and economic activities. Timely observation of foundation settlement helps to reduce the possibility of disasters caused by foundation settlement. At present, during the construction of track line roads, it is necessary to use a subgrade settlement monitoring and recording device to measure whether the construction road surface has settlement problems.
[0003] Existing track line subgrade settlement detection recorders generally only measure by burying a single measuring rod into the soil. If extreme weather such as storms is encountered during outdoor measurement, it may cause the detection device to tilt or even fall, affecting the measurement work. Based on this, we propose an improvement to a track line subgrade settlement detection recorder. Content of the Utility Model
