Description

Technical Field

[0001] This invention relates to a proportional simulation system and method for underground pipeline deformation in pipe jacking, belonging to the field of pipe jacking pipeline deformation monitoring. Background Technology

[0002] During the construction of a foundation pit, project managers typically use monitoring methods to assess the safety of the pit itself and its surrounding environment. Pipelines are one element of the environmental monitoring; monitoring personnel indirectly monitor them by setting up monitoring points on the road surface above the pipelines. However, the deformation at these monitoring points is affected by various factors, such as vehicle traffic, pedestrian weight, and road subsidence caused by the foundation pit construction. Therefore, the monitored values ​​remain indirect and cannot directly represent the actual deformation of the pipelines, potentially leading to safety incidents related to pipeline deformation. Conversely, directly measuring the deformation of pipelines, as they are part of underground infrastructure, presents significant challenges. Summary of the Invention

[0003] To address the problem that direct deformation of pipelines is difficult to monitor in existing technologies, and indirect monitoring data cannot directly represent the actual deformation of pipelines, this application provides a proportional simulation system and method for underground pipeline deformation within a pipe jacking system.

The driving wheel can drive the conveyor belt to rotate and affix the labels on top to the pipeline.

[0017] Furthermore, the pipeline elevation adjustment device uses an electric threaded rod for elevation adjustment.

[0021] The method for proportionally simulating the deformation of underground pipelines within the jacking pipe includes the following steps:

[0022] Step 1: Prepare the mobile reconnaissance device, simulation device, and control terminal, and connect the control terminal to the mobile reconnaissance device and simulation device.

[0023] Step 2: Place the mobile trolley inside the jacking pipe and directly below the pipeline. The control terminal controls the mobile trolley to move along the length of the pipeline. Mark the monitoring points on the pipeline using the monitoring point marking device. Measure the vertical distance between each monitoring point and the mobile trolley using the rangefinder. Collect positioning chip data through the base station to determine the three-dimensional coordinates of the mobile trolley.

[0024] Step 3: The control terminal controls the first moving device to move along the first track according to the location of the monitoring point, so that the top of the pipeline elevation adjustment device is located at the simulated monitoring point; the control terminal calculates the elevation of each monitoring point according to the received three-dimensional coordinate data of the moving trolley and the vertical distance between the monitoring point and the moving trolley, and adjusts the elevation of the simulated monitoring point of the simulated pipeline by controlling the pipeline elevation adjustment device.

Several spaced supports are provided on the conveyor belt for placing labels. The labels have an adhesive layer on top and a reflective layer on the bottom; the driving wheel can drive the conveyor belt to rotate and affix the labels on top to the pipeline.

[0032] Step two involves marking monitoring points on the pipeline using a monitoring point marking device, specifically including:

[0033] When the control terminal determines that the moving trolley has moved directly below the monitoring point, the moving trolley stops moving;

[0034] The control terminal controls the extension and retraction of the telescopic structure to match the position of the driven wheel with the position of the pipeline.

[0035] Control the drive wheel to rotate, which in turn drives the conveyor belt to rotate, so that the topmost label comes into contact with the pipeline and is affixed to it.

[0036] This invention, by employing the above technical solutions, has the following advantages and positive effects compared to existing technologies: The system can determine the real-time three-dimensional coordinates of the mobile trolley through a base station and positioning chip, and determine the three-dimensional coordinates of the monitoring points of the pipeline inside the jacking pipe by combining a rangefinder. Then, the control terminal controls the first moving device on the first track to slide to the simulated monitoring point position, and the elevation of the simulated monitoring point of the simulated pipeline is adjusted by the elevation adjustment device, thereby visually displaying the deformation of the pipeline through the simulation.

[0048] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a proportional simulation system and method for underground pipeline deformation within a pipe jacking system, based on the present invention. The advantages and features of the present invention will become clearer from the following description. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0049] Example 1

[0050] like Figures 1 to 6 As shown, excavation of the foundation pit causes changes in soil pressure, resulting in deformation of the jacking pipe. The pipelines installed inside the jacking pipe deform due to the pipe deformation and changes in pipeline tension. This embodiment provides a proportional simulation system for the deformation of underground pipelines inside a jacking pipe. It collects pipeline data using technical means and simulates the deformation of the pipelines inside the jacking pipe using a simulated pipeline in a simulation device, thereby visually displaying the deformation.

[0051] like Figure 1 As shown, the proportional simulation system for underground pipeline deformation in pipe jacking provided in this embodiment includes a mobile reconnaissance device 10, a simulation device 20, and a control terminal 30.

[0052] Combination Figure 1 and Figure 2As shown, the mobile reconnaissance device 10 includes a mobile trolley 11, a monitoring point marking device 12, a rangefinder 13, a positioning chip, and a base station matched with the positioning chip, all mounted on the mobile trolley 11. The mobile trolley 11 can move along the length of the pipeline 2 within the jacking pipe 1. The monitoring point marking device 12 can mark the positions of monitoring points on the pipeline 2, and the rangefinder 13 can measure the distance between the mobile trolley 11 and each monitoring point. The positioning chip is mounted on the mobile trolley, and the base station is deployed around the jacking pipe as needed. By collecting data from the positioning chip, the base station can determine the three-dimensional coordinates of the mobile trolley 11.

[0053] Combination Figures 1 to 4 As shown, the simulation device 20 includes a simulated jacking pipe 21, a simulated pipeline 22, a first track 231, a first moving device 232, and a pipeline elevation adjustment device 233. The first track 231 is set along the length of the simulated jacking pipe. Based on the position of the pipeline 2 in the jacking pipe 1, the position of the simulated pipeline 22 in the simulated jacking pipe 21 is determined. Then, the first track 231 is positioned directly below the simulated pipeline 22. Several first moving devices 232 are mounted on the first track 231. Each first moving device 232 can move a pipeline elevation adjustment device 233 to a simulated monitoring point on the simulated pipeline 22. The simulated monitoring point is a position on the simulated pipeline 22 corresponding to the position of the pipeline monitoring point; this correspondence needs to consider proportional scaling. One end of the pipeline elevation adjustment device 233 is connected to the first moving device 232, and the other end is fitted onto the simulated pipeline 22 to adjust the elevation of the simulated pipeline 22. The pipeline elevation adjustment device 233 can be in the form of a hydraulic rod, or a manual or electric threaded rod. The top of the pipeline elevation adjustment device 233 is fitted onto the simulated pipeline 22 through a collar and can slide along the length of the pipeline.

[0054] The control terminal 30 is used to collect measurement data from the rangefinder 13, control the movement of the mobile trolley 11, and control the monitoring point marking device 12 to mark monitoring points on the pipeline. It can determine the three-dimensional coordinates of the monitoring points by combining the vertical distance between the mobile trolley 11 and the monitoring points. The control terminal 30 can also control the slider in the simulation device 20 to move along the first track 231 and control the pipeline elevation adjustment device 233 to adjust the elevation of the simulated pipeline 22. The control terminal 30 can be a server, tablet computer, mobile phone, or dedicated device that performs the above functions.

[0055] The underground pipeline deformation simulation system provided in this embodiment can determine the real-time three-dimensional coordinates of the mobile trolley 11 through the base station and positioning chip, and determine the three-dimensional coordinates of the monitoring point of the pipeline 2 inside the pipe jacking 1 in combination with the rangefinder 13. Then, the first moving device 232 on the first track 231 is controlled by the control terminal 30 to slide to the simulated monitoring point position, and the elevation of the simulated monitoring point of the simulated pipeline 22 is adjusted by the pipeline elevation adjustment device, so as to intuitively display the deformation of the pipeline through the simulated pipeline 22.

[0056] It should be noted that the mobile trolley 11 includes a battery, a drive mechanism, and rollers. The battery provides power to the drive mechanism, which may include a motor and a transmission mechanism. The drive mechanism drives the rollers to rotate, enabling the mobile trolley 11 to move along the length of the pipeline within the jacking pipe. The mobile trolley 11 can be implemented using existing technology.

[0057] In one specific embodiment, the mobile trolley 11 is equipped with a lighting facility 14. The lighting environment inside the jacking pipe is relatively ordinary, and the lighting facility 14 can provide a light source for the jacking pipe.

[0058] In one specific embodiment, the mobile trolley 11 is equipped with an internal probe 15. When the lighting facility 14 is illuminated, the internal probe 15 transmits data to the control terminal 30 in real time.

[0059] In one specific embodiment, a clearing rod 16 is provided on the mobile trolley 11, and the clearing rod 16 is located at one end of the mobile trolley 11 in the forward direction. This is mainly because the mobile trolley 11 may encounter foreign objects when it moves forward inside the jacking pipe. When encountering foreign objects, the clearing rod 16 can maintain a reasonable distance between the foreign objects and the trolley, protecting the various devices of the trolley. The clearing rod 16 can remove existing foreign objects by rotating the front rod.

[0060] In one specific embodiment, the mobile trolley 11 is equipped with a sound monitor, which can monitor in real time whether the pipeline inside the jacking pipe emits abnormal sounds. It also sends monitoring data to the control terminal 30 via a signal receiving / transmitting sensor, enabling real-time detection of pipeline ruptures within the jacking pipe, such as water pipe ruptures or gas pipe ruptures. Upon detecting abnormal sounds, it immediately notifies relevant personnel for emergency repairs. Furthermore, the simulated jacking pipe 21 includes a sound simulator 243, a second track 241, and a second moving device 242. The second track 241 is parallel to the first track 231. The second moving device 242 is mounted on the second track 241 and can move along its length. The sound simulator 243 is mounted on the second moving device 242 and is transported to a designated position on the second track 241 via the second moving device 242. The control terminal 30 can control the sound simulator 243 to emit preset sounds, such as flowing water sounds or gas leak sounds, which can be preset according to the specific scenario requirements.

[0061] In one specific embodiment, a gas monitor is installed on the mobile trolley 11 to collect data on whether there is a gas leak inside the jacking pipe. The monitor transmits monitoring data to the control terminal 30 via a signal receiving / transmitting sensor, and immediately notifies relevant personnel for emergency repairs upon detection of a gas leak. Furthermore, a gas simulator 253, a third track 251, and a third moving device 252 are installed in the simulated jacking pipe 21. The third track 251 is parallel to the first track 231. The third moving device 252 is mounted on the third track 251 and can move along its length. The gas simulator 253 is mounted on the third moving device 252 and is transported to a designated position on the third track 251 via the third moving device 252. The control terminal 30 can control the gas simulator 253 to emit a preset gas, and the gas type can be distinguished by color.

[0062] In one specific embodiment, combined with Figure 1 , Figure 2 , Figure 5 , Figure 6As shown, the monitoring point marking device 12 includes a telescopic structure 121, a support structure 122, and a tracked transport mechanism 123 mounted on the support structure 122. The support structure 122 can be in the form of a support frame, a support sleeve, etc. The tracked transport mechanism 123 includes a driven wheel 125 mounted on top of the support structure 122, a driving wheel 124 mounted below the support structure, and a conveyor belt 126 wound around the driven wheel 125 and the driving wheel 124. Several spaced supports 127 are provided on the conveyor belt 126 for placing labels 128. The labels 128 are mounted on the supports 127, and the top of the labels 128 is provided with an adhesive layer and the bottom is provided with a reflective layer. When the mobile trolley 11 moves to the preset position, the telescopic structure 121 drives the support structure 122 to approach the pipeline 2, and the drive wheel 124 of the tracked transport mechanism 123 rotates at a certain angle, causing the conveyor belt 126 to rotate, so that the topmost label 128 is attached to the pipeline 2.

[0063] In one specific embodiment, the elevation adjustment device uses an electric threaded rod for elevation adjustment. The control terminal 30 sends deformation data ΔD to the elevation adjustment device, and the thread pitch is ΔH. Then the rotation angle of the electric threaded rod is 360°×ΔD / ΔH, with clockwise direction for rising and counterclockwise direction for falling.

[0064] In one specific embodiment, height-adjustable bases 26 are provided at both ends of the simulated jacking pipe 21. Based on the three-dimensional coordinates of the moving trolley 11, the three-dimensional coordinates of the jacking pipe 1 can be calculated, and the height of the simulated jacking pipe 21 can be further calculated. By adjusting the height of the height-adjustable bases 26, the height of the simulated jacking pipe 21 can be adjusted to simulate the elevation change of the jacking pipe.

[0065] It should be noted that the first moving device 232, the second moving device 242, and the third moving device 252 can have the same structure. They can be small vehicles that slide or roll along a track, including drive components and batteries, etc. They can be implemented using existing technology, and their specific structures are not limited.
