Measuring device for measuring upward arching and sinking of roadbed in horizontal hole
The invention provides a measuring device for measuring upward arching and sinking of a roadbed in a horizontal hole, which comprises a steel sleeve inserted into the horizontal hole of a soil body at the lower layer of the roadbed, the bottom of the steel sleeve is provided with a plurality of measuring ports arranged at intervals along the length direction of the steel sleeve, and a plurality of probe devices arranged corresponding to the plurality of measuring ports are arranged in the steel sleeve. And the probe device can detect the upward arching amount or the sinking amount of the roadbed at the measuring port through the measuring port. The steel sleeve is inserted into the horizontal hole drilled in the subgrade lower-layer soil body, the probe device is also installed in the horizontal hole along with the steel sleeve, the measuring opening is reserved in the bottom of the steel sleeve, and the probe device can conveniently conduct upward arching or sinking measurement on the external rock body through the measuring opening. The measuring device is buried in the horizontal hole of the lower-layer soil body of the roadbed, the influence on excavation and filling work above the measuring position is small, and real-time monitoring on upward arching and sedimentation of the roadbed below by the filling and excavation work above can be achieved.
本发明提出了一种水平孔内测量路基上拱下沉的测量装置，包括插入路基下层土体水平孔中的钢套管，钢套管的底部具有沿其长度方向间隔设置的多个测量口，钢套管中安装有与多个测量口对应设置的多个探头装置，探头装置能够通过测量口检测测量口处路基的上拱量或下沉量。本发明将钢套管安插在路基下层土体中钻出来的水平孔里，探头装置也随钢套管一起安装在水平孔里，钢套管底部留有测量口，便于探头装置通过测量口对外部岩体进行上拱或下沉测量。本发明的测量装置埋设在路基下层土体的水平孔里，对测量位置上方的挖方、填方工作影响较小，可实现对上方填方、挖方工作对下方路基上拱、沉降的实时监控。
