Description

[0002] In the construction of various pipeline projects such as immersed tube tunnels, the precise installation and stable posture of pipe segments play a key role in the quality and safety of the project. However, the existing pipe segment posture measurement technology has significant defects. Commonly used inclinometers have prominent problems in measuring the pipe segment posture. For example, their small size makes it difficult to ensure parallelism with the longitudinal and transverse axes of the pipe segment when installed, resulting in large deviations in the measurement data after the immersed tube is installed. In addition, the inclinometer has a zero drift phenomenon and must be calibrated before each use, resulting in complicated operation. If there is a problem in the calibration link, the measurement accuracy will be directly reduced, and it is difficult to obtain the pipe segment posture information in real time during the measurement process. Once a problem occurs, it often takes a lot of time and cost to rework, which is not conducive to quickly and accurately analyzing the trend of changes in the pipe segment posture, and cannot provide effective support for real-time decision-making and adjustment of the project.

[0043] The data acquisition module 10 includes a transverse distance meter 4 and a longitudinal distance meter 5. The transverse distance meter 4 is arranged above the first vertical section 21, and is used to measure and collect first distance information from the transverse distance meter 4 to the liquid surface in the first vertical section 21 in real time. The longitudinal distance meter 5 is arranged above the second vertical section 31, and is used to measure and collect second distance information from the longitudinal distance meter 5 to the liquid surface in the second vertical section 31 in real time.

[0044] The data processing module 20 is used to receive the first distance information and the second distance information, calculate the lateral inclination angle of the lateral rangefinder 4 and the longitudinal inclination angle of the longitudinal rangefinder 5 according to the first distance information and the second distance information, and establish a geometric posture model of the pipe segment 1 according to the lateral inclination angle, the longitudinal inclination angle and the geometric parameters of the pipe segment;

[0045] The display terminal 30 is used to display the geometric posture model of the pipe segment 1 in real time;

[0046] The early warning module 40 is used to store and analyze the historical data processed by the data processing module 20, and predict the posture change information of the pipe segment 1. When the posture change of the pipe segment 1 exceeds the preset safety threshold, the early warning module 40 controls the display terminal 30 to send a warning signal.

[0047] In one or more embodiments, Figure 1 , Figure 2 As shown, the first connecting pipeline 2 includes two first vertical sections 21 and one first horizontal section 22. The first horizontal section 22 is horizontally arranged on the bottom plate of the pipe section 1. Both ends of the first horizontal section 22 extend to the side walls 11 on the left and right sides of the pipe section 1. Both ends of the first horizontal section 22 are connected to the first vertical section 21. The two first vertical sections 21 are symmetrically arranged on the left and right side walls 11 of the pipe section 1.

[0048] The transverse distance meter 4 is installed on the side wall 11 of the pipe segment 1 and is located above the first vertical section 21, and is used to measure and collect the first distance information from the transverse distance meter 4 to the liquid level in the first vertical section 21 in real time; two transverse distance meters 4 are installed on one first connecting pipeline 2, and the two transverse distance meters 4 form a group, and the two transverse distance meters 4 in the same group have the same height.

[0049] In one or more embodiments, Figure 1 , Figure 3 As shown, the second connecting pipeline 3 includes two second vertical sections 31 and one second horizontal section 32. The second horizontal section 32 is longitudinally arranged on the bottom plate of the pipe segment 1. Both ends of the second horizontal section 32 extend to the end plates 12 at the front and rear ends of the pipe segment 1. Both ends of the second horizontal section 32 are connected with the second vertical section 31. The two second vertical sections 31 are symmetrically arranged on the front and rear end plates 12 of the pipe segment 1.

[0050] The longitudinal distance meter 5 is installed on the end plate 12 of the pipe segment 1 and is located above the second vertical section 31, and is used for real-time measurement and collection of second distance information from the longitudinal distance meter 5 to the liquid level in the second vertical section 31; two longitudinal distance meters 5 are installed on a second connecting pipeline 3, and the two longitudinal distance meters 5 form a group, and the two longitudinal distance meters 5 in the same group have the same height.

[0051] In an optional embodiment, if Figure 2-Figure 4 As shown, the data processing module 20 performs tilt calculation based on the data collected by the transverse distance meter 4 and the longitudinal distance meter 5. When analyzing and calculating the transverse inclination angle, such as when the pipe section is tilted, the measurement values ​​of the two transverse distance meters 4 corresponding to the same first connecting pipeline 2 will be different;

[0052] Assume that the first distance information of the liquid surface in the first vertical section 21 measured by the two horizontal distance measuring instruments 4 are h and 1 and h 2 , the distance between the two lateral rangefinders 4 is d, then the lateral inclination angle θ of the lateral rangefinder 4 is 1 for:

[0053] tanθ 1 =|h 1 -h 2 | / d

[0054] According to the above formula, the lateral inclination angle θ at the lateral rangefinder 4 can be calculated 1 Since the transverse distance meter 4 is installed on the side wall 11 of the pipe segment 1, the transverse inclination angle θ 1 is the lateral inclination angle of pipe segment 1 at this height;

[0055] When analyzing and calculating the longitudinal inclination angle, for example, when the pipe section is tilted, the measured values ​​of the two longitudinal distance measuring instruments 5 corresponding to the same second connecting pipeline 3 will be different;

[0056] Assume that the second distance information of the liquid surface in the second vertical section 31 measured by the two longitudinal distance measuring instruments 5 are h and 3 and h 4 , the distance between the two transverse rangefinders 4 is l, then the longitudinal inclination angle θ of the longitudinal rangefinder 5 2 for:

[0057] tanθ 2 =|h 3 -h 4 | / l

[0058] According to the above formula, the longitudinal inclination angle θ at the longitudinal rangefinder 5 can be calculated 2 Since the longitudinal distance meter 5 is installed on the end plate 12 of the pipe segment 1, the longitudinal inclination angle θ 2 is the longitudinal inclination angle of pipe segment 1 at this height;

[0059] The positions of the transverse distance meter 4 and the longitudinal distance meter 5 are calibrated on the pipe segment 1 to obtain the relative position relationship between the transverse distance meter 4 and the longitudinal distance meter 5 and the pipe segment 1, and the coordinates of the transverse distance meter 4 and the longitudinal distance meter 5 on the pipe segment 1 are input into the data processing module 20 data, so as to correspond the transverse inclination angle and the longitudinal inclination angle to the pipe segment 1;

[0060] The data processing module 20 then establishes a geometric posture model of the pipe segment 1 based on the lateral inclination angle, the longitudinal inclination angle and the geometric parameters of the pipe segment 1, wherein the data processing module 20 includes a CPU, a communication interface, a control algorithm unit, a drive circuit and a memory, etc.;

[0061] The data processing module 20 imports the lateral inclination angle, longitudinal inclination angle and geometric parameters of the pipe segment 1 into the graphics software, and uses the graphics software to generate a geometric posture model of the pipe segment 1, such as importing relevant data into OpenGL, and drawing a real-time three-dimensional model of the pipe segment 1 through OpenGL drawing point, line and surface commands.

[0062] The measurement system of this embodiment performs real-time data measurement through the transverse rangefinder 4 and the longitudinal rangefinder 5, effectively improving the accuracy of the measurement of the posture of the pipe segment 1, and processes the real-time measured data through the data processing module 20 to establish a geometric posture model of the pipe segment 1, and displays it in real time through the display terminal 30, thereby realizing real-time monitoring of the posture of the pipe segment 1, being able to promptly detect slight changes in the posture of the pipe segment 1, and providing real-time decision-making basis for engineering construction, and predicting the posture change information of the pipe segment 1 through the early warning module 40. When the posture change of the pipe segment 1 exceeds the preset safety threshold, the early warning module 40 controls the display terminal 30 to send a warning signal to notify the construction personnel to take corresponding adjustment measures to avoid engineering quality accidents caused by posture problems.

[0063] In an optional implementation, a wireless communication module is also included, and the lateral rangefinder 4 and the longitudinal rangefinder 5 transmit the collected data to the data processing module 20 in real time through the wireless communication module. In order to ensure the stability and accuracy of data transmission, a low-power, high-reliability wireless communication protocol such as ZigBee or LoRa is adopted.

[0064] In an optional embodiment, the safety threshold of the lateral inclination angle is 1°, and the safety threshold of the longitudinal inclination angle is 3.4°;

[0065] When the lateral inclination angle and the longitudinal inclination angle of the pipe segment 1 after the posture change exceeds the above safety threshold, the warning module 40 controls the display terminal 30 to issue a warning signal.

[0066] In an optional embodiment, in the present application, the length of the first vertical section 21 and the second vertical section 31 is 0.5 to 0.6 times the height of the pipe section 1. For example, when the height of the pipe section 1 is 7 meters, the length of the first vertical section 21 and the second vertical section 31 can be 4 meters.

[0067] The liquid level of the first vertical section 21 is 0.7 to 0.8 times the length of the first vertical section 21. For example, when the length of the first vertical section 21 is 4 meters, the liquid level in the tube can be 3 meters.

[0068] The liquid level height of the second vertical section 31 is 0.7 to 0.8 times the length of the second vertical section 31 . For example, when the length of the second vertical section 31 is 4 meters, the liquid level height in the tube can be selected to be 3 meters.

[0069] In one or several embodiments, the second connecting pipes 3 are arranged at intervals along the transverse direction of the pipe segment 1 .

[0070] In an optional embodiment, the heights of the transverse distance meters 4 arranged on adjacent first connecting pipes 2 are all different. The transverse inclination of different parts of the pipe segment 1 is comprehensively analyzed and calculated by using the measurement data of multiple groups of transverse distance meters 4 at different heights.

[0071] In an optional implementation, the first connecting pipe 2 is a transparent water pipe.

[0072] In one or several embodiments, the second connecting pipes 3 are arranged at intervals along the transverse direction of the pipe segment 1 .

[0073] In an optional embodiment, the heights of the longitudinal distance meters 5 arranged on adjacent second connecting pipes 3 are all different. The longitudinal inclination of different parts of the pipe segment 1 is comprehensively analyzed and calculated by using the measurement data of multiple groups of longitudinal distance meters 5 at different heights.

[0074] In an optional implementation, the second connecting pipe 3 is a transparent water pipe.

[0075] In an optional implementation, system errors such as the accuracy error of the rangefinder and the non-parallel installation of water pipes in the measurement system are analyzed, and compensation is performed by regularly calibrating the rangefinder, using high-precision calibration equipment, and introducing correction factors to further improve the measurement accuracy.

[0076] In an optional implementation, taking into account the possibility that multiple monitoring systems may be running simultaneously in actual projects, the design of this measurement system focuses on compatibility with other common monitoring systems (such as stress monitoring systems, displacement monitoring systems, etc.), and adopts standardized data interfaces and communication protocols to ensure that this measurement system can interact and share data with other monitoring systems.

[0077] In an optional implementation, by fusing data with other monitoring systems, a more comprehensive and in-depth monitoring of the status of the pipe segment 1 can be achieved. For example, by combining the posture data of the pipe segment 1 with the stress data, the deformation trend of the pipe segment 1 under stress can be more accurately analyzed, providing a more reliable basis for the safety assessment of the project.

[0078] In an optional implementation, this measurement system is not only suitable for common pipeline projects such as urban underground integrated pipeline corridors, cross-river and cross-sea tunnels, but can also be extended to different types of pipeline projects such as oil and gas pipelines, mine tunnel pipelines, etc., to provide accurate posture monitoring data for the construction and operation and maintenance of various pipelines.

[0079] In an optional implementation, the measurement system is optimized for adaptability in some special environments, such as pipeline projects in deep sea, high altitude, strong corrosion, etc. For example, waterproof, corrosion-resistant, and high-pressure resistant sensors and equipment are used to ensure that the measurement system can operate stably and reliably in harsh environments and realize real-time monitoring of pipe joint posture.

[0080] In one or more embodiments, at least two measuring towers are arranged on the top of the pipe segment 1, and a GNSS (Global Navigation Satellite System) is installed on each measuring tower to measure the position information and orientation information of the pipe segment 1 in real time through the GNSS;

[0081] The position information and orientation information are then transmitted to the data processing module 20 in real time via the wireless communication module. The data processing module 20 optimizes the geometric posture model of the pipe segment 1 according to the position information and orientation information of the pipe segment 1, and obtains the spatial position of the pipe segment 1, so that the operator can observe the position and posture of the pipe segment 1 in real time through the display terminal 30, and monitor the displacement and inclination of the pipe segment 1.
