TECHNICAL FIELD
[0001] The present application relates to the technical field of soil settlement measurement, and in particular to a soil layered settlement monitoring system. BACKGROUND
[0002] In the field of geological engineering, it is very important to accurately measure the settlement of underground soil. The traditional settlement meter adopts the principle of pull rod, and the settlement plate on the ground is fixedly connected with the pull rod of the settlement meter. When the underground soil settles, the settlement will be transmitted to the ground, so that the settlement plate drives the pull rod of the settlement meter to settle synchronously, and then the settlement amount of the underground soil is obtained by measuring the change value of the pull rod. In actual geological environment, the soil usually presents a layered structure. Due to the difference in physical properties of different soil layers, the settlement amount of each layer of soil is different under the action of external load or natural factors, so that the gap is generated between the soil layers. The existing settlement meter can only detect the settlement of the whole underground soil, and cannot detect the settlement of each layer of soil, so that the staff cannot timely find the geological disasters induced by the gap between the soil layers, and there is a safety hazard. SUMMARY
[0003] Therefore, the present application provides a soil layered settlement monitoring system for detecting the layered settlement amount of soil, which comprises an inclinometer, a settlement meter main body and a settlement magnetic ring.
[0004] The inclinometer is suitable for being installed in a settlement hole for settlement detection, and the settlement meter main body is arranged in the inclinometer.
[0005] The settlement meter main body comprises two or more detection units arranged in series, and the two or more detection units extend along the length direction of the inclinometer.
[0006] The settlement magnetic ring is sleeved on the outside of the inclinometer, and the settlement magnetic ring is two or more. The two or more settlement magnetic rings are respectively located at different soil layer positions in the settlement hole and are respectively arranged in one-to-one correspondence with the detection units, so that the detection area of each detection unit corresponds to the displacement range of one settlement magnetic ring.
[0007] The settlement magnetic ring is fixedly sleeved on the outer wall of the inclinometer through a soluble connecting piece. The soluble connecting piece is suitable for being dissolved in water so that the settlement magnetic ring can move along the length direction of the inclinometer with the settlement of the soil layer.
[0008] In a possible implementation manner, the two or more settlement magnetic rings are arranged at intervals along the length direction of the inclinometer.
[0009] In a possible implementation manner, a preset distance is arranged between each adjacent two settlement magnetic rings, and the preset distance is in the range of 1m-3m.
[0010] In a possible implementation, the soluble connecting piece is a water-decomposable adhesive tape.
[0011] In a possible implementation, the two or more detection units each comprise a magnetostrictive sensor and a pipe body; each adjacent two pipe bodies are fixedly connected through a quick plug, and the magnetostrictive sensor is arranged in the pipe body.
[0012] In a possible implementation, the sedimentation meter further comprises a collecting device; the collecting device is electrically connected to the sedimentation meter body and is adapted to receive data collected by the sedimentation meter body.
[0013] In a possible implementation, the sedimentation meter further comprises a mounting kit; the mounting kit is connected to the first detection unit of the sedimentation meter body; and a cable of the collecting device passes through the mounting kit and is connected to the sedimentation meter body.
[0014] Advantages of the present application
[0015] The sedimentation magnetic ring generates a constant bias magnetic field around it, the magnetostrictive sensing element and the detection coil in the detection unit are in the bias magnetic field, the current pulse passes through the magnetostrictive sensing element to generate a transient magnetic field, which triggers the magnetic domain rearrangement in the superposition area with the bias magnetic field of the sedimentation magnetic ring, and then generates a strain wave propagating along the axis of the magnetostrictive sensing element. Since the length of the magnetostrictive sensing element is fixed and the strain wave speed is known, the displacement of the sedimentation magnetic ring can be calculated by measuring the time difference of the strain wave emitted by the current pulse to the detection coil.
[0016] The present application arranges a plurality of sedimentation magnetic rings along the axis of the inclinometer pipe, and the sedimentation magnetic rings in different soil layers are one-to-one corresponding to the detection units. The sedimentation magnetic rings and the corresponding detection units work cooperatively. Each sedimentation magnetic ring is temporarily fixed to the outer wall of the inclinometer pipe by means of the soluble connecting piece during installation, and each sedimentation magnetic ring corresponds to a different soil layer. The corresponding sedimentation magnetic ring and detection unit use the magnetostrictive principle, so that the detection system can detect the settlement of each soil layer. When the soluble connecting piece dissolves in water, the sedimentation magnetic ring can displace along the length direction of the inclinometer pipe with the soil layer where it is located, thereby ensuring that the sedimentation magnetic ring and the soil layer where it is located displace synchronously. The soil layering settlement monitoring system of the present application enables the staff to master the settlement dynamics of different layers of soil, and quickly judge whether a gap is generated between the soil layers due to settlement differences based on the detection data, so that corresponding measures can be taken in advance, and geological disasters induced by uneven settlement of soil layers can be effectively prevented and controlled.

[0026] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.
[0027] This application proposes a soil stratified settlement monitoring system for detecting the amount of stratified settlement of soil, such as... Figure 1 , Figure 2 As shown, it includes: a settlement gauge body, an inclinometer tube 400, and a settlement magnetic ring 200; the inclinometer tube 400 is suitable for installation in a pre-drilled settlement hole for settlement detection; the settlement gauge body is disposed inside the inclinometer tube 400, and the settlement gauge body includes two or more detection units 100 arranged in series, the two or more detection units 100 extending along the length of the inclinometer tube 400; the settlement magnetic ring 200 is sleeved on the outside of the inclinometer tube 400, and there are two or more settlement magnetic rings 200, two of which are arranged in series. The settlement magnetic rings 200 are located at different soil layers in the settlement hole and are respectively set up in correspondence with the detection units 100, so that the detection area of each detection unit 100 covers the displacement range of one settlement magnetic ring 200. The settlement magnetic ring 200 is fixedly sleeved on the outer wall of the inclinometer tube 400 by a soluble connector. The soluble connector is suitable for dissolving in water so that the settlement magnetic ring 200 can move along the length of the inclinometer tube 400 as the soil layer settles.
[0028] It should be noted here that the inclinometer casing 400 is suitable for providing a mounting base for the settlement meter main body and the magnetic ring. The pre-prepared settlement hole requires to be punched to the bedrock position. The inclinometer casing 400 is installed in the settlement hole and the bottom end of the inclinometer casing 400 abuts on the bedrock in the settlement hole, thereby avoiding displacement of the inclinometer casing 400 following the settlement of the soil body. The plurality of detection units 100 arranged in series extend along the length direction of the inclinometer casing 400. The plurality of detection units 100 respectively detect the displacement of the settlement magnetic ring 200 at different soil layer positions. The settlement of the soil layer where the settlement magnetic ring 200 is located is further obtained. The settlement magnetic rings 200 are arranged at intervals along the outer side wall of the inclinometer casing 400. Each settlement magnetic ring 200 corresponds to a soil layer at a different depth. When each soil layer settles, the corresponding settlement magnetic ring 200 moves with the soil layer. The corresponding detection unit 100 of the settlement meter main body determines the settlement amount of the corresponding soil layer by inducting the displacement amount of the settlement magnetic ring 200. In the installation process of the soil layering settlement monitoring system, the soluble connecting piece serves as a temporary fixing device to accurately position the settlement magnetic ring 200 on the outer side wall of the inclinometer casing 400. In this way, the position of the settlement magnetic ring 200 in the initial installation stage is accurate. After the soil layering settlement monitoring system is installed and put into use, the soluble connecting piece gradually dissolves under the action of the moisture in the soil layer, thereby releasing the constraint on the settlement magnetic ring 200. The settlement magnetic ring 200 can move along the length direction of the inclinometer casing 400 with the settlement of the soil layer. The displacement range of each settlement magnetic ring 200 is within the detection area coverage range of the corresponding detection unit 100. When the soil settles, the settlement magnetic ring 200 moves with the soil. The detection unit 100 can detect the displacement of the settlement magnetic ring 200 in real time, thereby obtaining the settlement data of the soil layer.
[0029] The soil layering settlement monitoring system is installed in the settlement hole, the inclinometer 400 is installed in the settlement hole previously drilled for settlement detection, the settlement magnetic rings 200 on the outer side wall of the inclinometer 400 are located at different soil layer positions correspondingly, the water in the soil layer reacts with the soluble connecting piece to cause the decomposition of the soluble connecting piece, so that the settlement magnetic ring 200 moves along the length direction of the inclinometer 400 with the settlement of the soil layer where the settlement magnetic ring 200 is located, the settlement magnetic ring 200 generates a constant bias magnetic field around the settlement magnetic ring 200, the magnetostrictive sensitive element and the detection coil in the detection unit 100 are in the bias magnetic field, the transient magnetic field generated by the current pulse passing through the magnetostrictive sensitive element triggers the magnetic domain rearrangement in the superposition area with the bias magnetic field of the settlement magnetic ring 200, and then generates a strain wave propagating along the axial direction of the magnetostrictive sensitive element. Since the length of the magnetostrictive sensitive element is fixed and the strain wave speed is known, the displacement amount of the settlement magnetic ring 200 can be calculated by measuring the time difference of the strain wave emitted by the current pulse to the detection coil and returned; when a certain soil layer settles relative to the inclinometer 400, the settlement magnetic ring 200 at the position of the soil layer moves with the settlement of the soil layer. Since the position of the inclinometer 400 and the settlement gauge body in the inclinometer 400 is fixed and unchanged, when the settlement magnetic ring 200 moves with the settlement of the soil layer where the settlement magnetic ring 200 is located, the detection unit 100 installed at the corresponding position in the inclinometer 400 detects the change data of the position of the settlement magnetic ring 200, and the detection unit 100 transmits the detected data to an external device through a bus for storage or use.
[0030] The present application sets a plurality of settlement magnetic rings 200 along the axial direction of the inclinometer 400, and the settlement magnetic rings 200 in different soil layers are set one by one corresponding to the detection unit 100. The settlement magnetic ring 200 and the corresponding detection unit 100 work cooperatively. Each settlement magnetic ring 200 is temporarily fixed to the outer side wall of the inclinometer 400 by means of the soluble connecting piece when installed, and each settlement magnetic ring 200 corresponds to different soil layers. The corresponding settlement magnetic ring 200 and the detection unit 100 use the magnetostrictive principle, so that the detection system can detect the settlement of each soil layer. When the soluble connecting piece dissolves in water, the settlement magnetic ring 200 can move along the length direction of the inclinometer 400 with the settlement of the soil layer where the settlement magnetic ring 200 is located, so as to ensure that the settlement magnetic ring 200 moves synchronously with the soil layer where the settlement magnetic ring 200 is located. The soil layering settlement monitoring system of the present application enables the staff to master the settlement dynamics of different layers of soil, and quickly judge whether a gap is generated between the soil layers due to the settlement difference based on the detection data, so that corresponding measures can be taken in advance to effectively prevent and control geological disasters induced by uneven settlement of the soil layers.
[0031] In a possible implementation, two or more sedimentation magnetic rings 200 are arranged at intervals along the length of the inclinometer tube 400.
