Description

Technical Field

[0001] The present application relates to the field of geological environment monitoring, and in particular to a layered marker structure and an automated monitoring system thereof. Background Art

[0002] In recent years, the phenomenon of ground subsidence has always occurred. The geological factors that lead to ground subsidence are mainly the increase of surface load or the decrease of groundwater content in the underground soft base. Therefore, it is necessary to adopt ground subsidence monitoring and early warning methods. At present, the layered marking technology is more commonly used to monitor the settlement of underground soft base, obtain relevant settlement data, and issue early warnings in a timely and targeted manner, and take corresponding control measures, providing important technical support for urban planning and construction.

[0003] Layered markers are marking points buried in different soil layers of the covering layer. The layered marker technology is to bury the markers on the top and bottom plates of different soil layers in the ground subsidence area and directly pass them through the ground. By combining with other layered markers and bedrock markers, the compression and expansion of different soil layers can be measured, thereby calculating the deformation of different soil layers and the total ground settlement.

[0004] At present, most of the monitoring technologies for layered markers are manual measurements, with low measurement frequency, low efficiency, and high manpower and material costs. In addition, in extreme weather conditions, field operations are very dangerous or even impossible. Static leveling is often used in existing technologies, but the installation location of the static level is easily affected by the environment, resulting in measurement deviations; currently, many technologies use layered pre-buried magnetic rings to achieve automated measurement, but the measured values ​​are all relative settlements, and the absolute settlement cannot be known.

[0042] Combination Figure 1-5 As shown, a layered mark structure 300 of the present application includes: a first Beidou satellite receiver 1, a first protective cover 2, a spherical scale 3, a first measuring mark rod 4 and a fixing frame 5; the first measuring mark rod 4 is buried in a soft base layer 100 and directly passes through the ground 200, the first protective cover 2 is arranged above the first measuring mark rod 4, and is fixedly connected to the ground 200, the first Beidou satellite receiver 1 is located on the outside of the first protective cover 2, the first Beidou satellite receiver 1 is fixedly connected to the first protective cover 2, the fixing frame 5 is arranged above the ground 200 at intervals, and the fixing frame 5 is fixedly connected to the first protective cover 2; the spherical scale 3 includes a spherical scale measuring rod 31 and a reading sensor 32, the spherical scale measuring rod 31 is located on one side of the first measuring mark rod 4 and extends into the ground 200, the top of the spherical scale measuring rod 31 is fixedly connected to the fixing frame 5, the reading sensor 32 is located on the reading side of the spherical scale measuring rod 31, the reading sensor 32 is slidably connected to the spherical scale measuring rod 31, the reading sensor 32 is located on the top of the first measuring mark rod 4, the reading sensor 32 is fixedly connected to the first measuring mark rod 4, and the reading sensor 32 is communicatively connected to the first Beidou satellite receiver 1.

[0047] like Figure 4-5 As shown, in some embodiments, the clamping device 6 also includes a locking mechanism 63, which is fixedly connected to the outer side of the benchmark clamp 62. The locking mechanism 63 is provided with a locking adjustment piece 631. The locking adjustment piece 631 is adjusted to limit the top of the first measuring benchmark 4 to the benchmark clamp 62.

[0048] Exemplarily, the locking mechanism 63 is evenly distributed on the cylindrical surface of the benchmark clamp 62 and fixed by countersunk screws. The locking adjustment member 631 is an adjustment screw. The locking mechanism 63 also includes a shell 632, a cavity 633, a pad 634, an upper locking block 635 and a lower locking block 636. The upper locking block 635 and the lower locking block 636 are installed in the space defined by the shell 632 and the cavity 633, wherein the upper locking block 635 and the lower locking block 636 are respectively connected to the cavity 633 by hexagon socket head screws. The upper locking block 635 can move up and down within a certain range of the cavity 633, and the lower locking block 636 moves outward or inward within a certain range of the cavity 633 to press the benchmark clamp 62.

After confirming that the horizontal adjustment plate 54 is in a horizontal state, the horizontal adjustment member 55 is fixedly connected to the horizontal adjustment plate 54 and the mounting plate 52 with a nut, thereby ensuring the verticality of the spherical grid measuring rod 31, which is conducive to ensuring that the measurement data is more accurate.

[0052] In some embodiments, the fixing frame 5 further includes a level bubble 56, and the level bubble 56 is fixedly connected to the top of the level adjustment plate 54. Exemplarily, two levels 56 perpendicular to each other are installed on the level adjustment plate 54, which can more intuitively display the horizontal state of the level adjustment plate 54, which is conducive to ensuring the verticality of the ball grid measuring rod 31.

Each bedrock marker structure 400 can correspond to multiple layered marker structures 300 for measurement, and multiple first measuring poles 4 are respectively placed on the top and bottom plates of different soft base layers 100 underground and directly pass through the ground 200, that is, each reference station can correspond to multiple measuring stations. The second measuring mark 73 settles along with the bedrock layer and transmits the settlement information to the reference station. The measuring station receives the settlement information at the layered mark structure 300 and obtains the settlement of the underground soft base layer 100 of the layered mark structure 300 relative to the surface of the layered mark structure 300. The Beidou satellite collects information from the reference station and the measurement values ​​to calculate the settlement of the surface of the layered mark structure 300 relative to the bedrock mark structure 400. The absolute settlement of the underground soft base layer 100 is then obtained after comprehensive calculation based on the known information. The Beidou satellite navigation system can transmit the monitored and calculated relevant settlement information to the user segment, thereby realizing the automatic monitoring of settlement data and making the measurement data more accurate.
