Problems solved by technology

[0003] The landslide displacement measuring instrument currently used has a small measurement range, so when the landslide is still in the stable sliding stage, the measuring instrument has exceeded the measurement range, and subsequent monitoring cannot be used, especially for the third stage of the landslide displacement. monitor
Therefore, it is difficult to predict the occurrence of landslides, and this measuring instrument can only measure the displacement of one point. In practical applications, there are more than one slip zone in many geological conditions. In this case, it cannot be used at all.
[0004] Moreover, the maintenance and data collection of existing measuring instruments are also troublesome. For example, the battery needs to be charged regularly, and the data collection needs to be collected on site, so it is impossible to collect data in real time.

Abstract

The invention discloses a multi-channel large deformation landslide displacement automatic monitoring device and method. The device comprises a steel wire rope which is used for being connected with an anchor bolt, and the steel wire rope is connected with a displacement monitoring device. According to the structure of the displacement monitoring device, the steel wire rope penetrates through a displacement measuring unit and then is connected with a steel wire rope tensioning gear, and the displacement measuring unit is connected with a mechanical type measuring sensor and / or an electronic type measuring sensor; in the steel wire rope tensioning gear, the steel wire rope is wound on a roller, a roller shaft is supported on a bearing pedestal, the roller shaft is further connected with an inner ring of a spiral plate spring, and an outer ring of the spiral plate spring is matched with a fixed gear ring which is fixedly mounted. By means of the multi-channel large deformation landslide displacement automatic monitoring device and method, due to the arrangement of the steel wire rope tensioning gear, monitoring precision is improved, wide-range monitoring is achieved, and whole process monitoring of landslide data at three stages can be completely achieved.

Description

technical field [0001] The invention relates to the field of landslide displacement monitoring, in particular to a multi-channel large-deformation landslide automatic displacement monitoring device and method. Background technique [0002] Slopes can be seen everywhere in mountainous areas. Due to the different geological conditions in the area, some slopes have slip zones between the upper surface and the lower substrate. These slip zones are usually within the range of tens of meters in depth. With the continuous change of geological conditions, the upper and lower substrates of the slip zone will move relative to each other, that is, slip occurs. The speed of slippage has a great relationship with the geological conditions of the area. Usually, the slippage will be divided into three stages: the first stage is in the slip initiation stage, and a slip zone will be formed in this stage; the second stage, The relative position of the slip zone changes very slowly, and the s...
