Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering, and in particular relates to a slope displacement detection device taking into account the lateral pressure of the slope. Background Art

[0002] The highway slope displacement monitoring device is one of the key tools for detecting slope stability. It can provide early warning signals before the slope becomes potentially dangerous, thereby helping management and construction teams take necessary measures to prevent landslides or other geological disasters.

[0003] A common slope displacement monitoring device is a GNSS monitoring device, which determines the position change of the slope monitoring point by receiving signals from satellites. In actual application scenarios, GNSS monitoring devices are fixedly installed at several key locations on the slope to regularly transmit the displacement of the monitoring points. GNSS monitoring devices have the following disadvantages:

[0004] (1) The installation cost of GNSS monitoring devices is relatively high. GNSS monitoring devices are usually composed of a variety of high-cost devices and technologies such as receivers, multi-mode antennas, RTK signal receivers, and solvers to achieve high-precision slope displacement monitoring. Because the GNSS monitoring device is fixed above the slope, if there are many slopes on the operating road section, the cost of using a GNSS monitoring device to monitor each slope will be very high.

[0005] (2) The maintenance cost of GNSS monitoring devices is high. Since GNSS monitoring devices rely on global satellite navigation data, they need to be calibrated regularly. In addition, since GNSS monitoring devices are fixed in outdoor environments for a long time, they also require specialized technicians to perform regular device maintenance.

[0006] (3) The installation of GNSS monitoring devices is difficult. For highway slopes in operation, drilling construction is required on the highway slopes so that the supporting rods of the GNSS monitoring device can be buried deep inside the slopes. In order to ensure the structural integrity and stability of the slopes, professional technicians are required to guide the construction team to carry out the construction and installation of the device during the drilling construction.

[0007] The freedom of choosing the installation point of GNSS monitoring devices is low. The choice of installation point of GNSS monitoring devices is often limited to the location where sufficient satellite signals can be received, resulting in not all ideal monitoring points on the slope being able to be installed with GNSS monitoring devices, and the installed GNSS monitoring devices may not be able to fully monitor the slope displacement. Utility Model Content

[0008] In view of the technical problems existing in the above-mentioned prior art, the utility model provides a slope displacement detection device which takes into account the lateral pressure of the slope, with the purpose of monitoring the overall displacement of the slope by using pressure monitoring without the need for high-cost devices; by adopting a pressure sensing module for monitoring and a splicable structure, when the device needs maintenance or is damaged, it is only necessary to directly purchase the corresponding sensor or mold to replace the wiring, which greatly reduces the professional maintenance requirements.

[0009] In order to achieve the above purpose, the scheme of the utility model is as follows:

[0010] A slope displacement detection device taking into account the lateral pressure of the slope comprises a splicable main structure, wherein the splicable main structure is composed of a plurality of detachably connected support members, each support member is composed of a columnar block and a triangular block installed at the bottom of the columnar block to form a spike structure, a protrusion is provided at one end of the columnar block, and a groove adapted to the protrusion is provided at the other end, and pressure sensing modules are respectively installed at both ends of the top of each support member.

[0011] Furthermore, it also includes a control chip, an NBIOT module and a power supply. The pressure sensing module and the NBIOT module are respectively connected to the control chip, and the power supply provides a working voltage for the control chip.

[0012] Furthermore, the number of the support members is determined according to the splicing length required for the splicing main structure, and the splicing length required for the splicing main structure is set according to the length of the bottom of different slopes.

[0013] Furthermore, the triangular block is an equilateral triangle, and the width of the triangular block is greater than or equal to the width of the protrusion and less than the width of the support member.

[0014] Advantages of the utility model

[0015] (1) The slope displacement detection device of the utility model taking into account the lateral pressure of the slope has a low cost. By using pressure monitoring to monitor the overall displacement of the slope, there is no need to use a high-cost device. In addition, the slope displacement detection device is a semi-permanent monitoring structure, which can be installed and disassembled according to the needs of slope displacement monitoring, without having to spend a high cost to install it on all slopes.

[0016] (2) The slope displacement detection device has a low maintenance cost. It uses a pressure sensing module for monitoring and a splicable structure. Therefore, when the device needs maintenance or is damaged, it only needs to purchase the corresponding sensor or mold and replace the wiring, which greatly reduces the professional maintenance requirements.

[0017] (3) The slope displacement detection device is easy to install. It does not require any construction on the slope and does not need to consider the original structure and stability of the slope. An ordinary worker only needs to place the device at the bottom of the slope and then use the spike structure of the device to press it into the ground to complete the installation.

[0018] (4) The slope displacement detection device is easy to carry and use. It consists of a plurality of detachable support parts to form a spliced ​​main body. When the device needs to be installed for slope displacement monitoring, the number of required support parts can be calculated according to the length of the slope bottom and carried to the slope site by a construction vehicle. After installation, it will automatically start working and transmit alarm information to the user in real time. BRIEF DESCRIPTION OF THE DRAWINGS
