Device and method for monitoring settlement of highway bridgehead roadbed in loess area
According to the loess area expressway bridgehead roadbed settlement monitoring device and method, a differential pressure type profile settlement detection method comprises the steps that a steel pipe is buried to a bedrock construction datum point through drilling, and the vertical displacement of a test point relative to the datum point is calculated through the hydraulic pressure difference between the test point and the datum point. A solar cell, a radio transmission module, a lightning protection device and the like are installed in combination with user requirements, and an intelligent roadbed differential settlement monitoring system is formed. Long-term roadbed settlement monitoring is achieved, an intelligent roadbed differential settlement monitoring system is formed, roadbed settlement after construction is simply and accurately predicted according to settlement monitoring data, the driving comfort and safety are improved, and bumping at the bridgehead in the loess area is eliminated.
本发明提供了黄土地区高速公路桥头路基沉降监测装置及方法，压差式剖面沉降检测方法通过钻孔埋设钢管到基岩建设基准点，通过测试点位与基准点位的液压差，计算出测试点相对于基准点的竖向位移。结合用户需求安装太阳能电池、无线电传输模块以及防雷设备等，形成智能化的路基差异沉降监测系统。实现长期路基沉降监测，形成智能化的路基差异沉降监测系统，根据沉降监测数据简单准确的预测路基工后沉降，提升行车的舒适性和安全性，消除黄土地区桥头跳车。
