Description

Technical Field

[0001] This utility model relates to the field of sensors, and in particular to a buried settlement gauge sensor for water transport engineering. Background Technology

[0002] In the construction of waterway engineering projects, the foundation construction is particularly critical. Currently, surcharge preloading is commonly used to treat soft soil foundations. During this process, to ensure construction quality, various sensors need to be deployed around the construction environment to monitor the soil conditions. Among these, embedded settlement gauges are an indispensable tool for monitoring foundation settlement. Traditional embedded settlement gauges consist of a settlement tube and a distance sensing tube, with the two tubes connected and their other ends fixed underground and above ground, respectively. The underground settlement distance is measured by recording the relative displacement between the settlement tube and the distance sensing tube. However, waterway engineering foundations are often composed of silt or dredged fill, which not only have low bearing capacity but are also prone to settlement in the surrounding area due to the large-area surcharge, causing the distance sensing tube's reference point to shift and significantly affecting the test results. Utility Model Content

[0004] This utility model provides an embedded settlement gauge sensor for waterway engineering, including a settlement tube, a distance sensing tube, and a monitoring platform. The distance sensing tube is sleeved on the settlement tube and measures and outputs the movement distance of the settlement tube relative to the distance sensing tube. The monitoring platform is located above the distance sensing tube, and the top of the monitoring platform has a storage groove. The top of the storage groove has a cover that can be inserted into the storage groove. Below the cover are telescopic rods, a distance sensor, and a rotary motor. The rotary motor is coaxially arranged with the cover. The distance sensor is connected to the rotation shaft of the rotary motor and its sensing direction is radial. Two telescopic rods are respectively located on the left and right sides of the distance sensor to allow the cover to protrude from the top of the storage groove.

[0005] Furthermore, the inner ring of the storage slot is provided with a baffle, and a return spring is provided below the baffle. When no external force is applied, the return spring causes one side of the baffle to protrude from the top of the storage slot, and the protrusion height of the baffle is not higher than the protrusion height of the cover.

[0006] Furthermore, a rubber ring is provided around the perimeter of the cover.

[0007] Furthermore, the top of the cover is provided with a reinforcing plate, the area of ​​which is larger than the area of ​​the storage slot.

[0008] Furthermore, the settlement gauge sensor also includes a transmission component. The bottom ring of the settlement tube is provided with an anchoring ring.

Several extension plates are arranged around the movable ring.

[0009] Furthermore, the monitoring platform is provided with a connecting plate along its circumference, and the connecting plate is provided with fixing holes.

[0010] By adopting the above technical solution, the beneficial effects of this utility model are: This invention features a monitoring platform at the top of a distance sensing tube, utilizing a rotatable distance sensor to monitor and warn of the sensor's horizontal position during the monitoring process. It also supports algorithms to correct for minute sensor offsets, thereby improving overall testing accuracy. Furthermore, by installing a transmission component at the bottom of the settlement tube, it enhances the monitoring of soil settlement around the settlement tube and increases the measurement range of the settlement tube.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0019] Reference Figure 1-3 This utility model provides an embedded settlement gauge sensor for waterway engineering, including a settlement tube 1, a distance sensing tube 2, and a monitoring platform 3. The distance sensing tube 2 is sleeved on the settlement tube 1 and measures and outputs the movement distance of the settlement tube 1 relative to the distance sensing tube 2. An existing magnetic ring or an electrical displacement sensor can be installed in the inner ring of the distance sensing tube 2 to test the movement distance of the settlement tube 1.

[0020] The monitoring platform 3 is located above the distance sensing tube 2. The top of the monitoring platform 3 is provided with a storage slot 31, and the top of the storage slot 31 is provided with a cover 4. The cover 4 can be embedded in the storage slot 31. Below the cover 4 are provided a telescopic rod 41, a distance sensor 42, and a rotary motor 43. The rotary motor 43 is coaxially arranged with the cover 4. The distance sensor 42 is connected to the rotation shaft of the rotary motor 43 and its sensing direction is radial. Two telescopic rods 41 are respectively located on the left and right sides of the distance sensor 42 to allow the cover 4 to protrude from the top of the storage slot 31. At least one reference point is selected around the sensor. During each measurement, the telescopic rod 41 extends to allow the distance sensor 42 to measure the distance from the sensor to the reference point. The sensor is preferably an optical distance sensor 42, which measures the actual distance traveled to the reference point, not the displacement. It is important to note that because settlement will change the sensing angle of the distance sensor 42, a distance sensor 42 with tracking rotation function can be selected. If the settlement distance is small, the overall settlement distance can be calculated using the Pythagorean theorem to correct the error. Alternatively, the test point can be a vertical strip, and the sensing point of the distance sensor 42 above it can be observed to determine the overall settlement distance and correct the error. The rotatable sensor allows multiple reference points to be selected, preventing settlement at a single reference point from causing testing errors.

[0021] To prevent soil from entering the storage tank 31 during testing, a baffle frame 5 is provided on the inner ring of the storage tank 31. A return spring 51 is located below the baffle frame 5. Without external force, the return spring 51 causes one side of the baffle frame 5 to protrude from the top of the storage tank 31, with the protrusion height of the baffle frame 5 not exceeding the protrusion height of the cover 4. Simultaneously, a rubber ring 44 is provided around the cover 4 to enhance the sealing effect on the storage tank 31. To increase the pressure resistance of the storage tank, a reinforcing plate 6 is provided on the top of the cover 4, with an area larger than the area of ​​the storage tank 31.

[0022] To increase the monitoring range of the settlement pipe 1, the settlement gauge sensor also includes a transmission component 7. An anchoring ring 11 is provided on the bottom ring of the settlement pipe 1. The transmission component 7 includes a movable ring 71 and extension plates 72. The movable ring 71 is fitted onto the settlement pipe 1 and located above the anchoring ring 11. Several extension plates 72 are arranged around the movable ring 71. To enhance the connection effect of the monitoring platform 3, a connecting plate 8 is provided around the circumference of the monitoring platform 3. The connecting plate 8 has fixing holes 81.

[0023] Working principle: Before testing, the entire sensor is buried in the soil, and the settling pipe 1 and connecting plate 8 are fixedly connected to the soil base block and bottom base block, respectively. The telescopic rod 41 is activated to extend the distance sensor 42 out of the receiving groove 31, and the distance to at least one reference point is recorded. During testing, the movement distance of the telescopic rod 41 and the distance between the distance sensor 42 and the reference point are recorded. If necessary, the movement distance of the telescopic rod 41 is corrected using an algorithm.
