Technical Field

[0001] The invention belongs to the technical field of slope engineering, and in particular relates to a slope monitoring device. Background Art

[0002] As the construction scale of various types of railways, highways, urban rail transit, urban roads, etc. in my country continues to expand, many construction projects need to be carried out in complex terrain. Slope engineering is an important part of infrastructure construction. The reliability of its implementation is directly related to the stability of the land and is of great significance to protecting people’s lives and property safety.

[0003] In order to ensure the reliability of slope engineering, it is generally necessary to monitor the slope in real time. The toughness of geological slopes is generally divided into four stages, namely the stability stage, the resistance stage (destruction stage), the recovery stage, and the adaptation stage. Slope monitoring can keenly determine the stage of slope toughness and take corresponding measures according to the deformation of the slope. Slope monitoring can timely grasp the changes in the slope, including surface displacement, water seepage changes, etc., and discover potential slope landslides, collapses, collapses and other disaster risks in advance, so as to take corresponding emergency measures in time to ensure the safety of people and property.

[0033] Example:

[0034] See also Figure 1-2 The slope monitoring device in the preferred embodiment of the present invention includes a rainfall and liquid level monitoring component 3, a stress monitoring component 4 and a deformation monitoring component 5, so as to respectively monitor the rainwater and underground water level, internal stress and deformation displacement of the slope 1 in real time, and set a monitoring host and a server to upload the monitoring data to the monitoring host and the server in real time, and perform risk assessment through relevant system software.

[0035] Specifically, if Figure 1 As shown in the figure, the present invention arranges multiple layers of fixed platforms 2 on the surface of the slope 1 at intervals along the inclination direction of the slope 1, each layer of fixed platforms 2 is arranged horizontally and extends continuously along the longitudinal direction of the slope 1, and the uppermost layer of fixed platforms 2 is arranged on the top of the slope 1.

[0036] Furthermore, the rainfall and liquid level monitoring component 3 in the preferred embodiment is connected to the monitoring host and server, and includes a rain gauge 301 and a liquid level meter 302, wherein the rain gauge 301 is arranged on the fixed platform 2 at the top of the slope 1 to monitor the rainwater to obtain the rainfall signal, and upload the rainfall signal to the monitoring host and server. The liquid level meter 302 is arranged on the slope 1, one end of which extends out of the surface of the slope 1, and the other end extends to the depth of the underground water level of the slope 1, so as to monitor the underground liquid level of the slope 1, obtain the underground water level signal, and upload the water level signal to the monitoring host and server.

[0037] Furthermore, the stress monitoring component 4 in the preferred embodiment is connected to the monitoring host and the server, and includes a sensor 403. The sensor 403 is configured in multiple types, and the multiple sensors 403 are all configured inside the slope 1 to sense the stress inside the slope 1 in real time, obtain the internal stress signal of the slope 1, and upload the internal stress signal to the monitoring host and the server.

[0038] Preferably, if Figure 2As shown in , the stress monitoring assembly 4 also includes a rod body 401 , and multiple sensors 403 are simultaneously fixed on the rod body 401 through a mounting base 402 , so that by driving the rod body 401 into the slope 1 , multiple sensors 403 are simultaneously set in the slope 1 .

[0039] It is understandable that the multiple sensors 403 can be arranged circumferentially along the rod body 401 at the same height, or can be arranged sequentially along the extension direction of the rod body 401 , which is specifically determined according to the setting requirements of the sensors 403 .

[0040] Preferably, the stress monitoring assembly 4 also includes a sleeve 404, which is sleeved on the outer circumference of the rod body 401 and the sensor 403, and one end of the rod body 401 extends out of the sleeve 404 to protect the sensor 403 when the sensor 403 is driven into the slope 1 along with the rod body 401, and after the installation is in place, the sleeve 404 is taken out to expose the sensor 403 to monitor the slope 1.

[0041] In actual use, the sensor 403 is first mounted on the rod body 401 through the mounting base 402 , and then the sleeve 404 is sleeved on the rod body 401 , and then the rod body 401 is driven into the slope 1 .

[0042] Furthermore, the deformation monitoring component 5 in the preferred embodiment includes a reference point and a control point; wherein the reference point is set on the fixed platform 2, including a reference point observation pier 501, a visual target 502 and a first static level 503, wherein the reference point observation pier 501 is set on the fixed platform 2, the visual target 502 and the first static level 503 are set on the reference point observation pier 501, and a monitoring visual instrument 506 is set at the front end of the slope 1 corresponding to the visual target 502, so as to identify and compare the visual target 502 by the monitoring visual instrument 506 to measure the absolute displacement of the corresponding reference point.

[0044] Correspondingly, the control point is also set on the fixed platform 2, including the control point observation pier 504 and the second static level 505 set on the control point observation pier 504, so as to measure the relative displacement between the control point and the reference point through the first static level 503 and the second static level 505. In the preferred embodiment, the control points are distributed in multiple positions of the slope 1, and are further preferably distributed in combination with the reference points to form an array structure with multiple rows and columns.

[0045] It is understandable that the absolute displacement of the control point can be obtained by adding the absolute displacement of the reference point and the relative displacement of the control point relative to the reference point. In the preferred embodiment, the control point is compared with the horizontal reference point and the vertical reference point respectively, so as to obtain the horizontal absolute displacement and the vertical absolute displacement of the control point respectively, so as to further increase the indicators for monitoring the deformation of the slope, effectively solve the problem of the limited monitoring range of the monitoring system, facilitate the use of more indicators to monitor the deformation of the slope, and the monitoring data is real and effective, and easy to use.

Figure 1 In the preferred embodiment shown, four horizontal reference points and four vertical reference points are provided respectively.

[0047] Preferably, a plurality of stress monitoring components 4 are respectively arranged below the reference point observation pier 501 and / or the control point observation pier 504 .
