Description

Technical Field

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

[0002] Geocell is widely used as a slope reinforcement method in various engineering slopes. It has the advantages of high welding point strength, flexibility and strength, long service life, no fear of damage from outdoor ultraviolet rays, and three-dimensional reinforcement. It can also be used with geotextiles and three-dimensional vegetation nets to increase the greening effect. In the field of mountain transportation construction, geocell support is often used in high slope sections of earth embankments to ensure the stability of the shallow surface of the slope. Existing engineering experience shows that the stress characteristics of geocells are related to deformation, and their deformation characteristics can reflect the support effect and slope stability. However, the stress characteristics of geocells are difficult to predict, and there is no better monitoring method. Traditional geocell slope monitoring uses manual daily inspections. This method is not only inefficient and has high labor costs, but also difficult to observe and detect the initial deformation of the slope, which can easily cause irreparable economic losses after the rainy season.

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0020] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on Figure 1 The orientation and position of the geocell automated monitoring device shown in the figure when normally placed are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contour of each component itself.

[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0022] The present invention provides a geocell automatic monitoring device, see Figure 1 , including: a geocell assembly 100, a sensor mechanism 200 and a data acquisition mechanism 300; the sensor mechanism 200 is installed on the geocell assembly 100; the data acquisition mechanism 300 is connected to the sensor mechanism 200 to record and transmit the data collected by the sensor mechanism 200.

[0023] By installing the sensor mechanism 200 on the geocell assembly 100, the sensor assembly is used to monitor the displacement and strain data of the geocell, and after the data acquisition mechanism 300 is connected with the sensor mechanism 200, the displacement and strain monitoring data are collected and transmitted. It can effectively carry out long-term and effective remote monitoring of the geocell and the slope, and has the advantages of intelligence, automation, economy and environmental protection.

[0024] In one embodiment, the sensor mechanism 200 includes a displacement sensor assembly 210 and a transmission line; the displacement sensor assembly is installed on the geocell assembly 100 to monitor the displacement and strain data of the geocell; one end of the transmission line is connected to the displacement sensor assembly, and the other end is connected to the data acquisition mechanism 300. The number of displacement sensor assemblies depends on the size of the geocell assembly 100. The arrangement spacing of the displacement sensor assemblies is 1-2m. The arrangement spacing of the displacement sensor assemblies at the exit of the potential sliding surface is 0.2-0.5m. The displacement sensor assemblies are arranged at the outer surface nodes 110 of each layer of geocells. The displacement sensor assembly 210 is a distributed optical fiber strain sensor.

[0025] After excavation to the design elevation, the transmission line 400 is buried in advance, one end of the transmission line is connected to the data acquisition mechanism 300, and the other end is connected to the displacement sensor component 210. After completion, the planting soil is backfilled in layers of 10~20cm on the slope. The shallow stability of the slope is checked and calculated to find the most dangerous sliding surface and determine the range of the dense layout of the displacement sensor. The shear outlet position of the potential sliding surface is densely arranged with a spacing of 0.2~0.5m, and the rest of the slope is evenly arranged with a spacing of 1~2m. The displacement sensor uses a distributed optical fiber strain sensor, which is set at the outer surface node 110 of each layer of geocell. The distributed optical fiber strain sensor is laid out on the outer surface of the geocell with epoxy resin glue, and the distributed optical fiber strain sensor is straightened when pasting. Multi-point monitoring of the three-dimensional strain field inside the soil is realized, and real-time monitoring of multiple parameters of soil strain and displacement deformation is achieved.

[0026] In one embodiment, the geocell automatic monitoring device further includes a solar power supply device 500 .

[0027] A solar panel is provided at the data acquisition and measurement and control device, and the solar power supply device 500 is connected to the front-end data acquisition and measurement and control device and the displacement sensor assembly to continuously supply power to them, thereby realizing continuous automatic intelligent monitoring.

[0028] In one embodiment, the geocell automated monitoring device further includes a wireless service base station. The data acquisition mechanism 300 includes a data remote transmission chip and an information control device. The displacement monitoring information is conveniently transmitted to the wireless service base station, and the user can remotely receive and process the information.

[0029] The displacement sensors of the present invention are arranged at the nodes where the geocell is prone to peeling and damage to monitor the displacement of the geocell. The most dangerous sliding surface in the shallow layer of the slope is determined by stability calculation. Displacement sensors are encrypted at the most likely shear-in and shear-out positions of the sliding surface to achieve accurate monitoring of the slope. An automatic monitoring system is set up. The observation data is obtained through the front-end data acquisition and measurement and control device and uploaded to the wireless service base station. The back-end equipment automatically downloads and analyzes the data. When the processed data reaches a critical value, an alarm signal is sent to the mobile terminal to achieve long-term, intelligent monitoring and liberate manual labor.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
