Abstract

A settlement measuring module for a vertical layer-by-layer continuous settlement gauge is disclosed, which can improve the constructability of the vertical layer-by-layer continuous settlement gauge by improving the structure of the sensor part mounted on the settlement measuring module to reduce the overall size of the settlement measuring module, thereby making the settlement measuring module small enough to be inserted into a 3-inch bore hole. A settlement measurement module for a vertical layered continuous settlement gauge is interconnected through a plurality of connecting pipes and measures the amount of settlement of the ground by detecting the movement of a rod when the ground settles. It includes a settlement sensor that is coupled to and supported by the plurality of connecting pipes and configured to detect the movement of the rod when the ground settles by contacting the outer surface of the rod, and a sensor anchor that is connected to the settlement sensor, supports the settlement sensor, and is fixed to the ground by being attached in a radial direction. The settlement sensor includes a housing part coupled to and supported by the plurality of connecting pipes, a bracket part coupled to and supported by the housing part, a gear part rotatably coupled to the bracket part and converting the linear motion of the rod that moves along the axial direction when the ground settles into rotational motion, and a sensor part coupled to the gear part and converting the rotational motion of the gear part into an electrical signal to detect the amount of settlement of the ground. The sensor part is an integrated sensor capable of single-phase output with guaranteed linearity for the 0° to 330° range and double-phase output with guaranteed linearity for the entire 0° to 360° range.

Description

Vertical Settlement Measurement Module for Multi-layer Continuous Settlement Gauge The present invention relates to a settlement measurement module for a vertical layered continuous settlement gauge. 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. Among these, the layer settlement gauge is installed at the same point as the pore water pressure gauge in areas of deep or high soft soil depths, and can measure the amount of consolidation settlement at different depths of the soft ground. Such a layered settlement gauge consists of a settlement measuring rod inserted into the ground and fixed to the ground, and a settlement measuring sensor module mounted on the settlement measuring rod that detects the amount of ground settlement by sensing the movement of the rod when ground settlement occurs. The settlement measurement sensor module comprises a first gear that rotates when in contact with the settlement measurement rod during axial movement of the settlement measurement rod, a second gear that rotates in mesh with the first gear, and a plurality of sliding resistance type potentiometer sensors coupled to the first gear and the second gear and detecting the rotation of the first gear and the second gear. Meanwhile, equipment used for measuring ground behavior is generally manufactured to a size that can be inserted into a 3-inch bore hole, whereas conventional layered settlement gauges are manufactured to a size that can be inserted into a 4-inch bore hole due to the volume of multiple sliding resistance type potentiometer sensors equipped in the settlement measurement sensor module. As a result, in order to use conventional layer settlement gauges together with other measuring equipment, additional equipment capable of 4-inch drilling had to be used, which not only reduced constructability but also increased construction costs.
