The invention relates to the technical field of pipeline settlement monitoring, and discloses a subway foundation pit construction pipeline settlement monitoring device which comprises a base, the base is provided with a guide rail hoisting assembly and a guide rail overturning assembly, the guide rail hoisting assembly is provided with a guide rail formed by multiple sections of butt joint combination, and the guide rail is parallel to the side wall of a subway foundation pit and extends downwards; a vertically-moving lift truck is arranged at the tail end of the subway foundation pit, and a ground penetrating radar is arranged on the side, facing the subway foundation pit, of the lift truck. Compared with the prior art, the device has the advantages that the device does not make contact with a pipeline, it is guaranteed that the pipeline is not damaged, the ground penetrating radar can scan multiple pipelines with different depths in the vertical moving process, the guide rail can be in butt joint and lengthened, the pipeline with the large burial depth can be monitored, the laser target and the laser range finder are adopted for achieving accurate sensing of the elevation, and the detection accuracy is improved. And the vertical position of the laser target is maintained by the liquid level in the static level gauge, so that a stable measurement reference surface can be provided, and the settlement monitoring accuracy is ensured.
本发明涉及管线沉降监测技术领域,本发明公开了一种地铁基坑施工管线沉降监测装置,它包括底座,底座设有导轨吊装组件和导轨翻转组件,导轨吊装组件设有多节对接组合形成的导轨,导轨与地铁基坑侧壁平行并向下沿伸,其末端设有垂直位移的升降车,升降车朝向地铁基坑的一侧设有探地雷达。本发明与现有技术相比的优点在于:不与管道发生接触,保证管道不遭受破坏,探地雷达垂直移动的过程中能够扫描多个不同深度的管线,导轨可对接延长,能够对埋深较大的管线进行监测,采用激光靶和激光测距仪实现高程的精准感知,激光靶垂直位置由静力水准仪内的液面维持,能够提供一个稳定的测量基准面,保证了沉降监测的准确度。
