Deep soil body settlement monitoring system
The invention relates to a deep soil body settlement monitoring system. The deep soil body settlement monitoring system is characterized in that a vertical drill hole is formed in a place needing settlement monitoring, a drop hammer is placed at the bottom of the vertical drill hole, the drop hammer is connected through a first end of a thin line sleeved with a sleeve, and meanwhile, the thin lineis exposed out of the sleeve by a preset length. The sleeve is fixedly arranged relative to the vertical drill hole, so that the drop hammer drives the thin line to descend together when the deep soil body sinks, and the sleeve cannot move along with the drop hammer. When the deep soil body settles to a certain extent, the second end of the thin line and an alarm switch can generate action causedby power, and the alarm switch is switched from an off state to an on state to realize electrification, so that an alarm signal is output. The scheme can be realized only through simple devices, professional equipment such as a static level gauge and a magnetic ring is not needed, professional participation is not needed in the whole monitoring process, and the whole system is convenient to install and operate and low in cost so that the system can be popularized and applied in underground engineering construction, and the use reliability is high.
本申请涉及一种深层土体沉降监测系统，在需要进行沉降监测的地方开设有竖向钻孔，并在竖向钻孔的底部放置有吊锤，通过套接有套管的细线的第一端连接吊锤，同时细线漏出套管预设长度。套管相对竖向钻孔固定设置，保证当深层土体下沉时吊锤会带动细线一起下降，而套管不会随之移动。在深层土体沉降到一定程度时，细线的第二端与报警开关之间将会有力的作用，报警开关由断开状态转变为闭合状态实现上电，从而输出报警信号。上述方案只需要简单的器件即可以实现，不需要静力水准仪、磁环等专业设备，整个监测过程不需要专业人员参与，并且整个系统的安装操作较为方便、成本低，从而能够在地下工程施工中普及运用，具有使用可靠性强的优点。
