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.

Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0037] See Figure 1 to Figure 9 , the embodiment of the present invention provides a landslide deep multi-integrated sensor deployment equipment, including a penetrating monitoring body 1 and a monitoring body deployment system 2 .

[0038] The penetrating monitoring body 1 includes a casing and a sensor penetrating shear 104, the casing extending vertically for lowering into a borehole. A mounting hole 1011 extending vertically is formed through the side wall of the sleeve, and vertical grooves extending vertically are formed on the opposite side walls of the mounting hole 1011 . The bushing is provided with a plurality of mounting holes 1011 spaced up and down, and each of the mounting holes 1011 is installed with the sensor penetrating shears 104, w...

Abstract

The invention provides a multi-integrated sensor layout equipment and a layout method in the deep part of a landslide. The penetrating monitoring body includes a casing and a sensor penetrating scissors. The sensor penetrating scissors are arranged in the shape of scissors, and the first blade and the second blade face each other vertically. Rotate or rotate backwards so that the sensor penetrating scissors have an initial position and a monitoring position; when the sensor penetrating scissors are in the initial position, the ends of the pressure-receiving parts of the first blade and the second blade are arranged at intervals up and down, and the sensor penetrating scissors When the scissors are at the monitoring position, the pressure parts move toward each other, and the shearing parts pass through the installation holes to shear the sliding body; the monitoring body layout system drives the sensor penetration shears to move from the initial position to the monitoring position. The beneficial effect of the technical solution proposed by the present invention is: a scissors-shaped sensor is installed on the casing to penetrate into the shear, and the shearing part is cut into the soil, and the force is balanced, and the requirements for the casing are small; the layout device is designed for local static force application, Static balance, not easy to turn over, low requirements for pull rope, and no entanglement.

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...
