Description

Smart Stability IOT System Interconnected with Continuous Sink, Point Water Pressure and Surface GPS for Securing Vulnerable Ground Stability The present invention relates to a smart stability IoT system for interlinking continuous settlement, point water pressure, and surface GPS to secure stability of vulnerable ground. Generally, during embankment work on soft ground, ground behavior is measured to determine the safety of the embankment structure, thereby enabling safe and economical construction execution. Surface settlement gauges, pore water pressure gauges, and layer settlement gauges are used to measure ground behavior. A surface settlement gauge measures the elevation of a settlement plate by leveling a reference point and a settlement rod connected to the surface settlement plate, thereby allowing for the measurement of the total settlement amount and settlement rate of soft ground. Pore water pressure gauges are installed at the same location as layer settlement gauges in areas of deep or high soft earth embankments, and can measure pore water pressure by depth or layer due to embankment load. Layered settlement gauges are installed at the same point as pore water pressure gauges in areas of deep or high soft soil depths, and can measure the amount of consolidation settlement at different depths of the soft ground. Meanwhile, conventionally, when measuring ground behavior, the aforementioned layer settlement gauges, pore water pressure gauges, and surface settlement gauges were installed individually at different locations. However, in this case, there was a problem in that it was difficult to measure under identical conditions due to the influence of drainage materials (paper drains, sand drains, etc.) and the soil environment. In addition, even if layer settlement gauges, pore water pressure gauges, and surface settlement gauges are installed in nearby sections, there was a problem in that measurements under the same conditions were practically difficult because the layer settlement or water pressure displacements were not the same. Therefore, conventionally, it was difficult to obtain accurate data when measuring ground behavior, and as a result, there was a problem with very low reliability of the measurement results.
