Layout equipment and layout method for multiple integrated sensors in deep part of landslide

Abstract

The invention provides layout equipment and a layout method for multiple integrated sensors in a deep part of a landslide, a penetration type monitoring body comprises a sleeve and a sensor penetration shear, the sensor penetration shear is arranged in a scissor shape, and a first blade and a second blade rotate oppositely or oppositely in the vertical direction, so that the sensor penetration shear has an initial position and a monitoring position; when the sensor penetration shear is located at the initial position, the ends of the pressed parts of the first blade and the second blade are arranged at intervals in the vertical direction, when the sensor penetration shear is located at the monitoring position, the pressed parts move oppositely, and the shearing part penetrates out of the mounting hole to shear the sliding body. And a monitoring body arrangement system drives the sensor penetration shears to move from the initial position to the monitoring position. The technical scheme provided by the invention has the beneficial effects that the scissor-shaped sensor penetration shear is mounted on the sleeve, and the shearing part is sheared into a soil body, so that the stress is balanced, and the requirement on the sleeve is low; and the arrangement device adopts a local static force application design, is balanced in static force, is not easy to turn over, has low requirements on a pull rope, and does not generate winding.

Description

technical field [0001] The invention relates to the technical field of geological disaster monitoring and prevention, in particular to a multi-integrated sensor layout equipment and a layout method in the deep part of a landslide. Background technique [0002] Landslides are one of the most widely distributed and frequently occurring geological disasters in nature, posing a huge threat to human living environment, natural resources, and water conservancy projects. According to reports, since the Three Gorges Reservoir was impounded for the first time in 2003, a large number of ancient landslides have re-slid under the periodic water level fluctuations and rainfall of the reservoir, which has great potential hazards. The deformation and failure of landslides is a dynamic spatio-temporal evolution process. The basic characteristics of landslides are highly correlated and matched with the evolution stage and evolution model, and the evolution process is often accompanied by mul...

Problems solved by technology

For example, the existing monitoring methods all install monitoring instruments in holes, which is suitable for deep inclinometers and groundwater level measurements, but it is difficult to accurately measure parameters such as pore water pressure and water content under in-situ conditions. When the deformation of the landslide increases, the instruments in the hole are often damaged and become invalid. It is difficult to realize the multi-information parameter monitoring technology of "multiple measurements in one hole" under in-situ conditions.

At the same time, when the soil on the side wall of the borehole is dense, and part of the sliding mass is composed of gravel soil or materials with a denser texture, the layout of multi-parameter sensors in the borehole is often challenging.
