Description

Technical Field

[0001] This application belongs to the field of pipeline deformation monitoring technology, specifically relating to a monitoring marker device for deeply buried pipelines. Background Technology

[0002] When performing deformation monitoring on pipelines, it is necessary to set deformation markers on the pipelines to monitor their displacement in real time.

[0003] In related technologies, deformation markers used to monitor pipeline displacement come into contact with the soil. Due to soil disturbance and other phenomena, the displacement of the deformation markers is affected, which in turn affects the accuracy of the data obtained through the deformation markers. Summary of the Invention

[0004] Based on the above-mentioned technical problems, this application provides a deep-buried pipeline monitoring marker device, which aims to reduce the impact of soil disturbance on the displacement of deformation markers to at least a certain extent, so as to ensure the accuracy of the data obtained through deformation markers.

[0005] This application is achieved through the following technical solution: A deep-buried pipeline monitoring and marking device includes: a clamp, fitted onto the outer circumference of the pipeline; a support plate connected to the clamp; a protective sleeve, detachably supported on the top surface of the support plate, the protective sleeve forming a protective space inside; a measuring rod connected to the top surface of the support plate, the measuring rod being spaced within the protective space; and a deformation mark installed on the top of the measuring rod, at least a portion of the deformation mark being located outside the protective sleeve.

[0006] In some implementations, the top surface of the support plate is a horizontal plane.

[0007] In some implementations, the measuring rod is threaded to the top surface of the support plate.

[0008] In some implementations, the protective sleeve is supported on the top surface of the support plate by backfill soil.

[0009] In some implementations, the deformation marker includes a monitoring target connected to the top of the measuring rod.

[0010] In some embodiments, the deformable marker further includes at least one of a reflector and a prism, the reflector and the prism being mounted on the monitoring target.

[0011] In some embodiments, the deformable marker further includes: a connecting rod, with its bottom end connected to the monitoring target and its top end for mounting the reflector; and a mounting plate, connected to the connecting rod, for mounting the prism.

[0012] In some embodiments, the clamp includes a first clamp body and a second clamp body that engage with each other, the first clamp body and the second clamp body forming an annular structure adapted to the pipeline.

[0013] In some embodiments, the first clamp is located above the second clamp, and the support plate is fixedly connected to the middle of the first clamp.

[0014] In some embodiments, the monitoring marker device further includes a protective pad disposed between the annular structure and the pipeline.

[0015] The buried pipeline monitoring marker device provided in this application has a clamp fitted onto the outer circumference of the pipeline, a support plate connected to the clamp, a measuring rod connected to the top surface of the support plate, and a deformation marker installed at the top of the measuring rod. Therefore, the deformation marker can be connected to the pipeline via the support plate and the measuring rod, allowing the deformation marker to move synchronously with the pipeline, thus enabling deformation monitoring of the pipeline. Because the protective sleeve is detachably supported on the top surface of the support plate, it will not shift due to pipeline deformation. Since a protective space is formed inside the protective sleeve, and the measuring rod is positioned within this space, it will also shift within the protective space when the measuring rod moves with the pipeline. The protective sleeve prevents soil disturbance from affecting the displacement of the deformation marker, ensuring that the deformation marker and measuring rod deform only with the pipeline's displacement and not under soil disturbance conditions, thereby guaranteeing the accuracy of the data obtained by the deformation marker.

Detailed Implementation

[0019] The technical solutions in this application will now be clearly and thoroughly described with reference to the accompanying drawings. Specifically, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0020] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0021] Underground projects are often surrounded by a dense network of underground pipelines (including but not limited to gas and water pipelines). Some of these pipelines are old and in disrepair, leading to aging and water leakage, which loosens the surrounding soil and can even create cavities. This imbalance disrupts the soil's equilibrium, damaging the surrounding environment and compromising the safety of the underground pipelines. This is especially true for pressure pipelines; in severe cases, it can endanger production, construction, and the safety of people's lives and property, causing economic losses and social harm. Therefore, it is necessary to monitor the deformation of underground pipelines using deformation markers to obtain information on their displacement and prevent the aforementioned problems from occurring.

[0022] In related technologies, for shallowly buried pipelines, monitoring points can be placed above the pipeline, with deformation markers directly fixed to the pipeline. However, when the pipeline is buried at a depth of 1 meter or more, the disturbance of the underground soil can significantly affect the deformation markers. This shallow burial method makes it difficult to guarantee the stability of the monitoring points, resulting in distorted monitoring data.

[0023] In addition, when monitoring pipelines buried at a depth of 1 meter or more, the monitoring is mostly used to monitor the vertical displacement of the pipeline, but the horizontal displacement cannot be effectively monitored.

[0024] Based on the above-mentioned technical problems, this application provides a deep-buried pipeline monitoring marker device, which can avoid contact between the soil and the marker used to monitor displacement. It aims to at least reduce the impact of soil disturbance on the displacement of the deformation marker to a certain extent, so as to ensure the accuracy of the data obtained through the deformation marker. It can also effectively monitor both the vertical displacement and horizontal position of the pipeline, thereby improving the comprehensiveness of the monitoring data.

[0025] Figure 1 A schematic diagram of the structure of a deep-buried pipeline monitoring and marking device 10 according to one or more embodiments of this application is shown. (In conjunction with...) Figure 1 The buried pipeline monitoring and marking device 10 provided in this application includes a clamp 110, a support plate 120, a protective sleeve 130, a measuring rod 140, and a deformation mark 150. The clamp 110 is sleeved on the outer circumferential surface of the pipeline 20, and the support plate 120 is connected to the clamp 110. The protective sleeve 130 is detachably supported on the top surface of the support plate 120, and a protective space is formed inside the protective sleeve 130. The measuring rod 140 is connected to the top surface of the support plate 120, and the measuring rod 140 is spaced within the protective space. The deformation mark 150 is installed on the top of the measuring rod 140, and at least a portion of the deformation mark 150 is located outside the protective sleeve 130.

[0026] The buried pipeline monitoring marker device 10 provided in this application has a clamp 110 sleeved on the outer circumference of the pipeline 20, a support plate 120 connected to the clamp 110, a measuring rod 140 connected to the top surface of the support plate 120, and a deformation marker 150 installed at the top of the measuring rod 140. Therefore, the deformation marker 150 can be connected to the pipeline 20 through the support plate 120 and the measuring rod 140, and the deformation marker 150 can move synchronously with the pipeline 20. Then, the deformation monitoring operation of the pipeline 20 can be performed through the deformation marker 150. Because the protective sleeve 130 is detachably supported on the top surface of the support plate 120, it will not shift due to the deformation of the pipeline 20 during deformation. Since a protective space is formed inside the protective sleeve 130, and the measuring rod 140 is spaced within this space, when the measuring rod 140 shifts along with the pipeline 20, it will shift within the protective space. The protective sleeve 130 prevents soil disturbance from affecting the displacement of the deformation marker 150, ensuring that the deformation marker 150 and the measuring rod 140 can only deform with the displacement of the pipeline 20, and will not shift under soil disturbance conditions, thereby guaranteeing the accuracy of the data obtained by the deformation marker 150. The specific details of the deep-buried pipeline monitoring marker device 10 will now be further described with reference to the accompanying drawings.

[0027] Figure 2 It shows Figure 1 The diagram shows the assembly of the clamp 110, support plate 120, protective sleeve 130, and measuring rod 140 with pipeline 20. (Combined with...) Figure 2In some embodiments, the clamp 110 includes a first clamp body 111 and a second clamp body 112 that engage with each other. The first clamp body 111 and the second clamp body 112 form an annular structure adapted to the pipeline 20, so that the clamp 110 can be fixedly mounted on the outer circumferential surface of the pipeline 20. Exemplarily, both the first clamp body 111 and the second clamp body 112 are semi-circular, and both ends of the first clamp body 111 and the second clamp body 112 protrude outward to form a mating plate 113. The mating plate 113 on the first clamp body 111 and the mating plate 113 on the same side of the pipeline 20 are connected by bolts, so that the clamp 110 can be fixedly mounted on the pipeline 20, so that the clamp 110 and the pipeline 20 are rigidly connected. This application uses a clamp 110 to encircle the outer periphery of the pipeline 20. When the clamp 110 is closed, it can be stably secured to the pipeline 20. As the position of the pipeline 20 changes in the soil, the clamp 110 and the components connected to it (support plate 120, protective sleeve 130, measuring rod 140, and deformation marker 150) can move accordingly to monitor changes in the pipeline 20 clamped by the clamp 110 in real time. Moreover, by clamping the clamp 110 onto the pipeline 20, the connecting rod 152 can be kept connected to the pipeline 20 for a long time, making the monitoring process more stable and ensuring monitoring stability. In addition, by adjusting the tightness of the bolts, the clamp 110 can also adapt to pipelines 20 of different diameters, making it highly adaptable and facilitating the assembly of the monitoring marker device 10 onto the pipeline 20.

[0028] In other configurations, the first clamp 111 and the second clamp 112 can be welded to the outer circumferential surface of the pipeline 20, which can also achieve a rigid connection between the clamp 110 and the pipeline 20. This application does not limit this.

[0029] Combination Figure 2 In some embodiments, the monitoring marker device 10 further includes a protective pad 160, which is disposed between the annular structure and the pipeline 20. The protective pad 160 can be made of rubber, which has a certain degree of elasticity. When the clamp 110 is clamped onto the pipeline 20, the protective pad 160 acts as a filler between the clamp 110 and the pipeline 20, making the connection between the clamp 110 and the pipeline 20 tighter. The protective pad 160 also prevents the clamp 110 from scratching the surface of the pipeline 20. Simultaneously, the elastic protective pad 160 has a high surface friction, which can prevent the clamp 110 from sliding along the axial direction of the pipeline 20, thus providing protection and reinforcement.

[0030] Combination Figure 2In some embodiments, the first hoop 111 is located above the second hoop 112, and the support plate 120 is fixedly connected to the middle of the first hoop 111 to achieve the assembly of the support plate on the clamp 110. Exemplarily, the top of the support plate 120 is provided with a groove, and the middle of the first hoop 111 is embedded in this groove. The portion of the first hoop 111 embedded in the groove is fixedly connected to the support plate 120 by welding or other means. The bottom of the remaining portion of the support plate 120 rests on the outer circumferential surface of the pipeline 20 so that the support plate 120 can move synchronously with the pipeline 20. During the installation of the support plate 120, tools such as a spirit level can be used to ensure that the top of the support plate 120 is horizontal, providing conditions for the subsequent installation of the measuring rod 140 and the protective sleeve 130.

[0031] Figure 3 A schematic diagram showing the assembly of the measuring rod 140, protective sleeve 130, and support plate 120 is provided. Figure 3 In some embodiments, a screw hole is provided at the center of the top surface of the support plate 120, and the bottom end of the measuring rod 140 is threaded into the screw hole of the support plate 120, so that the measuring rod 140 is threadedly connected to the top surface of the support plate 120. In order to ensure the reliability of the connection between the measuring rod 140 and the support plate 120, a nut can be fitted on the bottom end of the measuring rod 140, and the nut is used to lock the bottom end of the measuring rod 140 to the top surface of the support plate 120.

[0032] Combination Figure 3 In some embodiments, the bottom of the protective sleeve 130 rests on the top surface of the support portion, and the protective sleeve 130 is loosely fitted onto the outer peripheral surface of the measuring rod 140. The protective sleeve 130 is not connected to the support portion. When the soil around the protective sleeve 130 is disturbed, the soil will exert a force on the protective sleeve 130. However, since the protective sleeve 130 is not connected to the support portion, the applied force will not be transmitted to the support plate 120, and correspondingly, it will not be transmitted to the measuring rod 140 connected to the support plate 120 or to the measuring rod 140. Deformation mark 150; In addition, even if the protective sleeve 130 is displaced due to soil disturbance, since the protective sleeve 130 is fitted with a gap on the outer circumference of the measuring rod 140, the displaced protective sleeve 130 will not come into contact with the measuring rod 140. Therefore, by setting the protective sleeve 130, the influence of soil disturbance on the displacement of the deformation mark 150 can be avoided, so that the deformation mark 150 and the measuring rod 140 can only deform with the displacement of the pipeline 20, and will not be displaced under the condition of soil disturbance, thereby ensuring the accuracy of the data obtained by the deformation mark 150.

[0033] When installing the protective sleeve 130, it is necessary to set the protective sleeve 130 and the measuring rod 140 coaxially and temporarily fix the protective sleeve 130 so that the protective sleeve 130 and the measuring rod 140 maintain displacement. During backfilling, the protective sleeve 130 is fixed by the backfill soil. After the backfilling is completed, the temporary fixation can be removed. That is, the protective sleeve is supported on the top surface of the support plate 120 by the backfill soil.

[0034] In some embodiments, the tip of the measuring rod 140 is located within the protective sleeve 130, so that the measuring rod 140 can be completely protected by the protective sleeve 130. In another embodiment, the tip of the protective sleeve 130 is flush with the soil surface, or the tip of the protective sleeve 130 protrudes from the soil surface. In this case, the tip of the measuring rod 140 may protrude from the tip of the protective sleeve 130. Of course, the tip of the measuring rod 140 may also remain within the protective sleeve 130. This application does not impose any limitations on this.

[0035] Figure 4 A schematic diagram of the assembly of the deformable mark 150 and the measuring rod 140 is shown. (Combined with...) Figure 4 In some embodiments, the deformable marker 150 includes a monitoring target 151, which is connected to the top end of the measuring rod 140. The monitoring target 151 serves as a physical marker fixed to the node to be measured on the pipeline 20, and its core function is to provide a stable spatial reference point for the monitoring system. When the pipeline 20 undergoes vertical displacement, the monitoring target 151 moves synchronously with the pipeline 20, and its spatial coordinate change directly reflects the amount of vertical displacement of the node in the pipeline 20. Exemplarily, the top end of the measuring rod 140 is threaded, and the monitoring target 151 is threadedly connected to the top end of the measuring rod 140.

[0036] In some embodiments, the deformable marker 150 further includes at least one of a reflector (not shown) and a prism (not shown), which is mounted on the monitoring target 151. The reflector and prism, in conjunction with measuring equipment such as a total station, utilize the principle of light reflection to obtain the three-dimensional coordinate changes of the nodes of pipeline 20, and then calculate the displacement of pipeline 20 (including vertical and horizontal displacement). Specifically, when the total station emits a laser beam to the reflector or prism, the reflector or prism reflects the light back to the total station along its original path. The total station calculates the distance to the reflector by measuring the round-trip time or phase difference of the laser, and determines the three-dimensional coordinates of the reflector by combining the horizontal and vertical angles. When pipeline 20 undergoes displacement, the coordinates of the reflector or prism change. The system calculates the displacement by comparing the initial coordinates with the real-time coordinates, thus confirming the displacement of pipeline 20.

[0037] Combination Figure 4In some embodiments, the modified marker 150 further includes a connecting rod 152 and a mounting plate 153. The bottom end of the connecting rod 152 is connected to the monitoring target 151, and the top end of the connecting rod 152 is used to mount a reflector. The mounting plate 153 is connected to the connecting rod 152 and is used to mount a prism. Exemplarily, the bottom end of the connecting rod 152 can be threaded onto the monitoring target 151, and the mounting plate 153 can be sleeved onto the middle of the connecting rod 152. The connecting rod 152, the mounting plate 153, and the monitoring target 151 can form an integral structure and be assembled together to the top end of the measuring rod 140.

[0038] It should be noted that although the modified symbol 150 shown in this application includes a connecting rod 152 for mounting the reflector and a mounting plate 153 for mounting the prism, in actual use, only the reflector can be mounted on the connecting rod 152; or only the prism can be mounted on the mounting plate 153, that is, only one of the prism and the reflector can be used. Of course, in other embodiments, the reflector can also be mounted on the connecting rod 152 and the prism can be mounted on the mounting plate 153 at the same time, that is, both the prism and the reflector can be used together. The specific configuration can be adjusted according to the needs, and this application will not elaborate on this.

[0039] In addition, in this application, the bottom of the connecting rod 152 can be located inside the protective sleeve 130 tube, while the connecting rod 152 for mounting the reflector and the mounting plate 153 for mounting the prism are both located outside the protective sleeve 130 tube, in order to avoid the related strategy of interference displacement of the protective sleeve 130.

[0040] The assembly process of the deep buried pipeline monitoring and marking device 10 provided in this application is as follows: 1. Excavate pipeline 20 until the top and bottom surfaces of pipeline 20 are exposed to provide working conditions for the installation of clamp 110; 2. Install clamp 110, align the first clamp body 111 and the second clamp body 112 of clamp 110, and connect the first clamp body 111 and the second clamp body 112 with bolts. At this time, tools such as a spirit level can be used to make the top surface of the support plate 120 horizontal, so as to provide conditions for the next step of installing the measuring rod 140 and the protective sleeve 130. 3. Install the measuring rod 140 and the protective sleeve 130. The bottom end of the measuring rod 140 is threaded onto the top surface of the support plate 120. After the measuring rod 140 is installed, install the protective sleeve 130. When installing the protective sleeve 130, the measuring rod 140 should be placed in the center position inside the protective sleeve 130, and the protective sleeve 130 should be temporarily fixed. Then, backfill the pipeline 20. After the backfilling is completed, remove the temporary fixation. 4. Install the monitoring target 151. The mounting plate 153 and connecting rod 152 on the monitoring target 151 are integral with the monitoring target 151. Install the monitoring target 151 on the top of the measuring rod 140, and the mounting plate 153 and connecting rod 152 can be assembled in place.

[0041] In summary, the deep-buried pipeline monitoring marker device 10 provided in this application, through the setting of the protective sleeve 130, can avoid the influence of soil disturbance on the displacement of the deformation marker 150, so that the deformation marker 150 and the measuring rod 140 can only deform with the displacement of the pipeline 20, and will not move under the condition of soil disturbance, thereby ensuring the accuracy of the data obtained by the deformation marker 150. In addition, it can also acquire the horizontal displacement data and vertical displacement data of the pipeline 20 in real time, so as to effectively monitor both the vertical displacement and horizontal position of the pipeline 20, improve the comprehensiveness of the monitoring data, and has good practicality.
