Description

Technical Field

[0001] The utility model relates to the technical field of surface deformation monitoring, in particular to a surface deformation monitoring device for a geotechnical engineering slope. Background Technique

[0002] Surface deformation monitoring is an important part of slope monitoring. At present, equipment such as level instruments and total station instruments are mostly used to detect the surface deformation of slopes. However, this monitoring method is relatively cumbersome, and data processing is relatively complex and not intuitive enough. Especially in areas with relatively steep terrain, it increases the measurement difficulty. Moreover, the existing deformation monitoring only monitors the generated inclination slope and cannot simultaneously monitor the horizontal displacement. In this way, more and more complex equipment is required.

[0003] In the patent with the publication number CN209277218U, a geotechnical slope surface deformation monitoring device is proposed. In this patent, it includes a first monitoring pile, a second monitoring pile, a level gauge, a first monitoring box, an alarm, a solar panel, a suspension wire, a gravity ball, a vibration sensor, a movable plate, a spring, a support frame, and a second monitoring box. A level gauge of model JZC - B2 is installed on the top surface of the support piles of the first monitoring pile and the second monitoring pile. The level gauge is used to determine whether the installation is balanced when installing the first monitoring pile and the second monitoring pile, to avoid installing them obliquely, so as to prevent inaccurate monitoring. A first monitoring box is installed on the top of the level gauge of the first monitoring pile, and a second monitoring box is installed on the top of the level gauge of the second monitoring pile. A suspension wire is installed on the top inner cavity of the first monitoring box and the second monitoring box. The bottom of the suspension wire is fixedly connected to a gravity ball. Vibration sensors of model SW - 420 are installed on both sides of the gravity ball. So when the slope deforms and tilts, the gravity ball deflects. When the deflected gravity ball hits the vibration sensor, the vibration sensor senses it and then transmits the signal to the alarm on the top. The alarm makes an alarm sound, which alerts the staff so that they can take measures, making the monitoring easier and more convenient. The first monitoring pile and the second monitoring pile are connected by a connecting wire, and the connecting wire is in a taut state. Then one end of the connecting wire at the second monitoring pile is located in the inner cavity of the second monitoring box. A spring is installed on one side of the suspension wire at the top inner cavity of the second monitoring box. The bottom of the spring is installed with a movable plate. And the end of the connecting wire at the second monitoring box is connected to the movable plate. If there is no slope tilt between the first monitoring pile and the second monitoring pile but a horizontal displacement occurs between them, the connecting wire will pull the movable plate. Due to the elastic effect of the spring, the movable plate deflects and hits the vibration sensor, and then the alarm will make an alarm sound for reminder, increasing the monitoring function and range. The spring can prevent the influence of wind direction and airflow on the stability of the connecting wire. Because the spring has an elastic stretching force, a slight pulling force cannot bend the spring, improving the sensitivity. The settings of the connecting wire, the spring, and the movable plate enable it to detect horizontal movement, thus improving the detection effect. The solar panel can absorb solar energy and convert it into electrical energy through an inverter, and then supply power to the first monitoring pile and the second monitoring pile, facilitating the power consumption of the first monitoring pile and the second monitoring pile. Moreover, solar energy is environmentally friendly. However, there are still the following problems in this patent:

[0004] When monitoring the surface of a geotechnical slope, it is difficult to ensure the stable protection effect of the monitoring pile when it is affected by vibration.

[0005] In view of the above problems, it is necessary to design a geotechnical slope surface deformation monitoring device to overcome the above problems. Utility Model Content
