Underground water level and deep-seated displacement same-hole monitoring device

Abstract

The invention discloses an underground water level and deep-seated displacement same-hole monitoring device, and relates to the technical field of geological monitoring.The device comprises an inclinometer pipe, an osmometer and an inclinometer, the osmometer is connected with a surficial reading device through a cable, and the osmometer can move up and down in the inclinometer pipe through ropes; the inclinometer can move along the inclinometer pipe to measure the offset distance of the inclinometer pipe.The inclinometer pipe is downwards put at the bottom of a drilled inclinometer hole, the osmometer is connected with the cable and then downwards put at the bottom of an osmosis pipe through the ropes, the other end of the cable is reserved at a hole opening of the inclinometer hole and connected with the reading device, and the underground water level can be read; the inclinometer can monitor deep-seated displacement data along the inclinometer pipe point by point.The underground water level and deep-seated displacement same-hole monitoring device has the advantages of being simple and compact in structure and capable of achieving same-hole monitoring of the underground water level and deep-seated displacement, the engineering cost for drilling holes is reduced, and the monitoring efficiency is improved.

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...

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
