Description
Technical Field
The utility model relates to a calamity early warning technical field especially relates to a side slope multivariate parameter measurement device.
Background
Landslide is one of the natural disasters which frequently occur, is widely distributed and has huge harm, and serious casualties, economic losses and environmental damages are caused every year.
At present, slope deformation monitoring is mainly divided into two categories, namely surface monitoring and underground deep monitoring. The land surface monitoring technology mainly adopts the technologies of GPS, remote sensing, three-dimensional laser scanning and the like, has the greatest advantage of large-area and large-area measurement, and can obtain information such as sliding direction, sliding scale and the like by comparing data in a certain time. However, the earth surface monitoring method is easily affected by climate, terrain, vegetation and human factors, the monitoring time interval is large, and real-time monitoring cannot be achieved. In addition, the sliding surface plays a key role in the development and evolution process of the landslide, the ground surface monitoring cannot acquire the information of the formation and the damage of the sliding surface in the side slope, and the weak geological activity which is continuously carried out in the deep part cannot be monitored. Landslide is essentially the result of the constant damage and destruction of the internal structure of the slope, so that information is sent from the inside to the outside, and only the interior of the slope can sense the original information. When the change that takes place inside the side slope is big enough, the earth's surface just can appear macroscopic deformation, and the deflection can only be caught by earth's surface monitoring facilities when reaching certain degree. In addition, the movement of the surface soil of the ground caused by rainfall erosion can be mistakenly judged as landslide by the ground surface monitoring equipment, and the interior of an upslope body can be stable actually. In summary, surface monitoring is easily interfered by various factors, the initial state of landslide disaster cannot be ascertained, and further early warning delay is caused, and false judgment and false alarm of landslide can be made due to the scouring movement of the superficial surface of the ground.
The underground deep monitoring technology mainly comprises the step of directly attaching a monitoring device to a side slope body, so that the direct information of the change of the side slope body can be acquired more efficiently and quickly. This method requires the rough position of the slide surface to be determined in advance in order to arrange the monitoring points at more representative positions. In the present deep monitoring technology, the application of a drilling inclinometer is the most common, but the main defect of the drilling inclinometer is that an inclinometer pipe is sheared when the sliding displacement reaches the centimeter level, so that the device fails and cannot be monitored continuously. Moreover, the installation direction of the sensor of the borehole inclinometer needs to be determined according to the sliding direction, so that the horizontal displacement of each depth can be accurately measured and the depth of the sliding surface can be positioned. If the slip direction is not well determined, the data monitored by the inclinometer may deviate significantly from the actual amount of slip. The acoustic emission monitoring technology has the characteristics of directness, reliability, low price, high precision and real-time online, and can early warn landslide in advance. However, at present, the acoustic emission wave guide tube is basically a metal tube, shear failure can occur when the deformation is small, large deformation cannot be monitored, and the deep large deformation measurement technology is a blank.

In an embodiment of the present invention, in order to avoid that the sliding surface 3 damages the sleeve 4 during the monitoring process, for example, the sleeve 4 is cut off, the sleeve 4 of this embodiment is arranged in the slider 2, wherein the sleeve 4 does not pass through the sliding surface 3. I.e. there is a certain distance between the bottom end of the sleeve 4 and the slide face 3.

In this embodiment, the diameter of the anchor cable is 20 mm. Of course, in practical applications, anchor cables with other diameters may be used according to practical requirements, and the implementation is not limited to this.
The anchor cable 7 of the present embodiment may be an anchor cable made of a flexible material.
The flexible material may include, but is not limited to, a steel material, and for example, the flexible material may be an alloy material or the like.
The position of the sliding surface 3 in the embodiment can be determined in various ways, for example, an inclination angle sensor can be uniformly distributed in 4 meters at the lower end of the anchor cable, and the position of the sliding surface 3 can be judged according to the inclination response of the section, or the position of the sliding surface where the shearing action occurs can be determined through deep analysis of acoustic emission parameters in the incubation period of the landslide.
It will be appreciated that the anchor cable 7 in this embodiment not only has a degree of stiffness to provide a reaction force, but also a degree of flexibility to allow a degree of lateral bending and shearing.
It should be noted that, in this embodiment, by means of the anchor cable 7 and the sleeve 4, along with the movement deformation of the sliding mass, the anchor cable 7 and the sliding head 8 slowly slide in the sleeve 4, and the sleeve 4 is gradually expanded without being suddenly broken, so that the deformation monitoring range and the slope stabilizing capability of the device are increased.
Specifically, in the process of monitoring the landslide by using the flexible monitoring device, when the sliding head 8 slides relatively in the sleeve 4, the sleeve 4 is gradually expanded, the whole sleeve 4 is gradually damaged from top to bottom, the performance of the material is exerted to the utmost extent, and the energy of the movement of the landslide body is converted and consumed in the processes of friction and expansion of the sleeve 4.

And the remote server analyzes and pre-warns the landslide according to the inclination angle data and the acoustic emission parameters, and gives an alarm when the deformation degree of the sliding body 2 exceeds a pre-warning threshold value.
