Problems solved by technology

[0003] At present, the deep displacement monitoring hole and the groundwater level monitoring hole are usually arranged independently, and the two monitoring contents are carried out independently, which increases the engineering cost of drilling. In addition, excessive drilling disturbance increases the risk of slope sliding. Therefore, the invention A device that realizes monitoring of groundwater level and deep displacement in the same hole has important engineering significance

Abstract

The invention discloses a monitoring device for underground water level and deep displacement in the same hole, which relates to the technical field of geological monitoring and includes an inclinometer, a piezometer and an inclinometer. The piezometer can move up and down along the inclinometer pipe through the rope; the inclinometer can move along the inclinometer pipe to measure the offset distance of the inclinometer pipe. Lower the inclinometer pipe to the bottom of the drilled inclinometer hole, connect the piezometer to the cable, and lower the piezometer to the bottom of the permeable pipe through a rope, and leave the other end of the cable at the inclinometer hole to connect with the reading instrument for reading The groundwater level is taken; the inclinometer can monitor the deep displacement data point by point along the inclinometer pipe. The invention has the advantages of simple and compact structure, can realize the monitoring of underground water level and deep displacement in the same hole, saves the engineering cost of drilling, and improves the monitoring efficiency.

Description

technical field [0001] The invention relates to the technical field of geological monitoring, in particular to a monitoring device for underground water level and deep displacement in the same hole. Background technique [0002] Deep displacement monitoring is an important part of landslide monitoring. It can not only provide early warning and prediction for the occurrence of landslides, but also find out the buried depth of potential sliding surfaces. At present, the method of drilling inclination measurement is mainly used for deep displacement monitoring, that is, a certain depth of borehole is drilled on the slope body by manual drilling, and then an inclinometer tube with a fixed guide groove is installed in the borehole. The inclinometer with guide wheels measures the offset distance of the inclinometer tube from bottom to top along the guide groove, so as to monitor the law of slope displacement with time. In addition, the groundwater level inside the landslide is al...
