Description

Technical Field

[0001] The present invention relates to the technical field of pipeline monitoring, and particularly to a pipeline early warning method, device, equipment, medium and product. Background Art

[0002] Currently, the research on the interaction between pipelines and soil under geological disasters mainly focuses on disasters such as earthquakes, landslides and fault activities, and the research on the mechanical response characteristics of buried pipelines under settlement is not deep enough.

[0003] Existing technologies usually use theoretical calculation methods based on statics, or use finite element and finite difference numerical simulation methods to determine the settlement of pipelines.

[0004] However, the theoretical calculation method based on statics is too simplified, with very low calculation reliability, and the calculation method does not consider the settlement process, so it is impossible to accurately calculate the safety of buried pipelines in any settlement state. The finite element and finite difference numerical simulation methods cannot reflect the discreteness of the soil mass, and rely on professional personnel for modeling, requiring a large amount of computing resources and time, with poor timeliness. For buried pipeline settlement disasters, in engineering, there is often a lack of stress and strain monitoring data of the pipeline body for long-term service buried pipelines, and only after obvious soil settlement is found will soil settlement monitoring be carried out in the settlement area, which results in a lack of surface displacement monitoring data during the initial development process of settlement. Therefore, it is difficult to accurately and effectively determine the stress safety of pipelines in the settlement area, and thus it is impossible to accurately determine the safety state of buried pipelines under settlement disasters.

[0031] Embodiment 1

[0032] Figure 1 The figure is a flowchart of a pipeline early warning method provided for Embodiment 1 of the present invention. This embodiment is applicable to the mechanical response of buried pipelines under the action of formation settlement. This method can be executed by a pipeline early warning device, which can be implemented in the form of hardware and / or software, and the pipeline early warning device can be configured in an electronic device. As Figure 1 shown, the method includes:

[0033] S110. Obtain the construction parameters of the target pipeline and the current soil mechanics parameters.

[0034] In this embodiment, the target pipeline can be understood as a pipeline buried underground that needs to be monitored. The construction parameters can be understood as the basic engineering parameters of the pipeline set during construction, such as the pipeline burial depth, pipe diameter, wall thickness, and steel grade, etc. The current soil mechanics parameters can be understood as parameters covering two major aspects of physical properties and mechanical properties. Through the mutual correlation and joint action of these parameters, the engineering characteristics and behavior performance of the soil mass are determined. For example, they can include density, cohesion, and friction angle, etc. These parameters can be obtained through laboratory tests or on-site tests, or can be estimated based on empirical data.

[0035] Specifically, during construction, the basic engineering parameters of the target pipeline can be recorded and saved in advance. When detecting the target pipeline, the processor can obtain the pre-stored construction parameters from the memory based on identifiers such as the pipeline number of the target pipeline to understand the state of the target pipeline during construction. Sensors can also be installed on the pipeline wall outside the target pipeline or through on-site collection by relevant personnel and other means to obtain the current soil mechanics parameters of the target pipeline to understand the current situation of the soil around the target pipeline.

[0036] S120. Determine the vertical external force loads of each cross-section of the target pipeline according to the construction parameters and the current soil mechanics parameters.

[0037] In this embodiment, the target pipeline's cross-sections can be understood as the target pipeline being divided into multiple segments. The cross-sections of the pipeline subjected to stress in each segment can be divided into, for example, the upper wall, lower wall, left wall, and right wall of the pipeline. Vertical external loads can be understood as external forces acting perpendicular to the horizontal plane. For example, these can include downward vertical external forces acting on the upper wall of the pipeline due to soil settlement, or upward vertical supporting forces acting on the lower wall of the pipeline.

[0038] Specifically, the processor can determine the pipeline condition of the target pipeline during construction based on the construction parameters. Then, based on the current pipeline condition, due to the different external forces caused by different soil volumes at different pipeline burial depths, the processor can adopt a strategy that matches the pipeline burial depth and combine the current soil mechanics parameters and construction parameters to determine the vertical external force loads on each section of the target pipeline.

[0039] S130: Construct a pipeline model based on the vertical external force load to determine the mechanical response state of the target pipeline.

[0040] In this embodiment, the pipeline model can be understood as the target pipeline simulated by the software. The mechanical response state can be understood as the specific behavior and reaction mode exhibited by the target pipeline when subjected to external loads, that is, the reaction state exhibited when receiving external loads (i.e., vertical external force loads).

[0041] Specifically, the processor can construct a pipeline model based on the pipeline parameters of the target pipeline, apply a vertical external force load to the pipeline model as an external load in the settlement area, and simulate the soil in the non-settlement area through other models, such as a soil spring model, and by running the pipeline model, the overall mechanical response state of the target pipeline can be obtained.

[0042] S140: Determine warning information of the target pipeline according to the mechanical response state and issue a warning.

[0043] In this embodiment, the warning information can be understood as information used to indicate which position of the target pipeline is subjected to concentrated force and poses a safety threat, and is used to locate high-risk areas of the target pipeline.

[0044] Specifically, the processor can determine the stress conditions of various parts of the target pipeline based on the mechanical response state. It can locate the location of stress concentration as a high-risk area, and generate early warning information containing the location and stress conditions to send early warning information to staff related to pipeline maintenance. For example, the information can be sent to the staff's equipment through pop-ups, messages, and emails to provide timely early warnings.

[0045] The technical solution of the embodiment of the present invention is to obtain the construction parameters of the target pipeline and the current soil mechanics parameters; determine the vertical external force loads of each section of the target pipeline according to the construction parameters and the current soil mechanics parameters; construct a pipeline model based on the vertical external force loads to determine the mechanical response state of the target pipeline; and determine the early warning information of the target pipeline and give an early warning according to the mechanical response state. By considering the soil conditions of the environment where the pipeline is located and the vertical external force loads of different pipeline sections, the mechanical response state of the target pipeline is determined, and then the high-risk parts in the target pipeline are located and early warned through the mechanical response state. It realizes the fast and effective calculation of the mechanical response of the buried pipeline under the action of formation settlement, improves the calculation and evaluation efficiency of the stress condition of the buried pipeline under the action of formation settlement, realizes the early warning of settlement danger in advance, and thus ensures the safety of the pipeline.

[0046] Embodiment 2

[0047] Figure 2 The following is a flowchart of a pipeline early warning method provided by the second embodiment of the present invention. This embodiment is a further refinement of the above embodiment. As Figure 2 shown, the method includes:

[0048] S201. Obtain the construction parameters of the target pipeline and the current soil mechanics parameters.

[0049] S202. Determine the vertical external force load strategy matching the pipeline burial depth in the construction parameters.

[0050] In this embodiment, the pipeline burial depth can be understood as the depth of the pipeline underground. The vertical external force load strategy can be understood as the strategy for determining the vertical external force load. Since the amount of soil above the pipeline is different at different pipeline burial depths, which will cause different external forces on the pipeline, different strategies can be used to accurately determine the vertical external force load.

[0051] Specifically, the vertical external force load strategies for different pipeline burial depths can be preset, and the processor can determine the set burial depth range to which the pipeline burial depth in the construction parameters belongs, and then determine the matching vertical external force load strategy.

[0052] Exemplarily, the vertical external force load strategies for different pipeline burial depths can be:

[0053] When the pipeline burial depth is 2m:

[0054]

[0055] When the pipeline burial depth is 2.5m:

[0056]

[0057] When the pipeline burial depth is 3m:

[0058]

[0059] When the buried depth of the pipeline is 3.5m:

[0060]

[0061] In the formula, X is the relative settlement between the pipe and the soil, with the unit of m, which can be calculated by the difference between the initial buried depth of the pipeline at the target section and the current buried depth of the pipeline. Y is the vertical external load, with the unit of kN / m.

[0062] For example, if the buried depth of the pipeline during construction is 2.8m and it is closest to 3m, the vertical external load strategy for a 3m buried depth of the pipeline can be adopted.

[0063] S203. Determine the load to be corrected for each section of the target pipeline based on the relative settlement between the pipe and the soil and the vertical external load strategy, where the relative settlement between the pipe and the soil is the difference between the buried depth of the pipeline during construction and the current buried depth of the pipeline.

[0064] In this embodiment, the relative settlement between the pipe and the soil can be understood as the change in the current buried depth of the pipeline relative to the buried depth of the pipeline during construction. The load to be corrected can be understood as an inaccurate vertical external load that needs to be corrected. Among them, the relative settlement between the pipe and the soil is the difference between the buried depth of the pipeline during construction and the current buried depth of the pipeline.

[0065] Specifically, the processor can input the relative settlement between the pipe and the soil into the vertical external load strategy to determine the load to be corrected for each section of the target pipeline.

[0066] S204. Correct the load to be corrected based on the current soil mechanics parameters to obtain the vertical external load.

[0067] Specifically, since different discreteness of the soil mass will bring different vertical external forces to the pipeline section. For example, the external force brought by loose soil mass is less than that of dense soil mass. The processor can determine the soil-related parameters based on the current soil mechanics parameters and correct the load to be corrected based on the soil-related parameters to obtain a vertical external load that is more in line with the actual situation.

[0068] Furthermore, based on the above embodiments, the step of correcting the load to be corrected based on the current soil mechanics parameters to obtain the vertical external load can be refined as:

[0069] Obtain the microscopic parameters of soil particles corresponding to the current soil mechanics parameters through the biaxial compression simulation experiment of the soil mass; correct the load to be corrected according to the pipeline diameter and the microscopic parameters of soil particles in the construction parameters to obtain the vertical external load.

[0070] In this embodiment, the biaxial compression simulation experiment of soil can be understood as a method for studying the mechanical behavior of soil under biaxial compression conditions through numerical simulation technology. The microscopic parameters of soil particles can be understood as a series of parameters that describe the characteristics and behaviors of soil particles at the microscopic level. For example, they can include soil particle density, particle friction coefficient, rolling resistance coefficient, effective modulus, and stiffness ratio.

[0071] Specifically, the processor can establish a biaxial compression simulation experiment of soil based on the current soil mechanics parameters to obtain the corresponding microscopic parameters of soil particles.

[0072] Among them, the microscopic parameters of soil particles include soil particle density, particle friction coefficient, and rolling resistance coefficient. Correspondingly, according to the pipe diameter in the construction parameters and the microscopic parameters of soil particles, the step of correcting the load to be corrected can be refined as follows:

[0073] a1. Determine the first correction factor according to the pipe diameter.

[0074] In this embodiment, the first correction factor is used to correct the deviation caused by the pipe diameter.

[0075] Specifically, the first correction factor can be calculated by the following formula:

[0076]

[0077] In the formula, D is the pipe diameter, with the unit of m; F(D) is the first correction factor.

[0078] b1. Determine the second correction factor according to the soil particle density.

[0079] In this embodiment, the soil particle density is used to reflect the density characteristics of the soil. The second correction factor is used for the deviation caused by the soil particle density.

[0080] Specifically, the second correction factor can be calculated by the following formula:

[0081]

[0082] In the formula, is the soil particle density, with the unit of kg / m 3 ; F( ) is the second correction factor.

[0083] c1. Determine the third correction factor according to the particle friction coefficient.

[0084] In this embodiment, the particle friction coefficient is used to reflect a physical quantity that measures the friction force between the particle and the pipe contact surface. The third correction factor is used for the deviation caused by the particle friction coefficient.

[0085] Specifically, the third correction factor can be calculated through the following formula:

[0086]

[0087] In the formula, fr is the particle friction coefficient; F(fr) is the third correction factor.

[0088] d1. Determine the fourth correction factor according to the rolling resistance coefficient.

[0089] In this embodiment, the rolling resistance coefficient is used to reflect the density characteristics of the soil mass. The fourth correction factor is used for the deviation caused by the rolling resistance coefficient.

[0090] Specifically, the fourth correction factor can be calculated through the following formula:

[0091]

[0092] In the formula, rrfr is the particle rolling resistance coefficient; F(rrfr) is the fourth correction factor.

[0093] e1. Correct the load to be corrected based on the first correction factor, the second correction factor, the third correction factor, and the fourth correction factor to obtain the vertical external force load.

[0094]

[0095] In the formula, Y end is the corrected vertical external force load of the pipeline, with the unit of kN / m.

[0096] S205. Establish a pipeline model corresponding to the target pipeline through the setting software.

[0097] In this embodiment, the setting software can be understood as the software used to construct the model, such as finite element software.

[0098] Specifically, the processor can use the construction parameters of the target pipeline as the basis and establish a virtual pipeline model corresponding to the target pipeline through the setting software.

[0099] S206. Apply the vertical external force load to the pipeline position in the settlement area of the pipeline model and apply pipeline constraint conditions to the pipeline model.

[0100] In this embodiment, the pipeline position in the settlement area can be understood as the pipeline position with soil settlement problems. The pipeline constraint conditions can be understood as those used to constrain the direction of pipeline movement caused by pipeline forces, such as the movement of the pipeline when subjected to vertical pressure.

[0101] Specifically, the pipeline constraint conditions can be set in advance according to the actual situation, and the settlement area can be simulated by vertical external force loads. The processor can apply the vertical external force loads to the pipeline positions in the settlement area of the pipeline model and apply the pipeline constraint conditions to the pipeline model to simulate the situation of the soil settlement part.

[0102] S207. Simulate the non-settlement area soil part in the pipeline model through the soil spring model.

[0103] In this embodiment, the soil spring model can be understood as a model that simplifies the soil into a combination of a spring and a damper with elastic and damping characteristics. The non-settlement area soil part can be understood as the position where the soil does not settle.

[0104] Specifically, since there will be a situation of pipe-soil separation in actual cases, in order to ensure correspondence with the real situation, the processor can simulate the non-settlement area soil part in the pipeline model through the soil spring model.

[0105] S208. Determine the mechanical response state of the target pipeline by running the pipeline model.

[0106] Specifically, after configuring the environment where the pipeline is located, the pipeline model can be run to obtain the overall mechanical response state of the target pipeline.

[0107] S209. Determine the stress condition of the target pipeline according to the mechanical response state.

[0108] In this embodiment, the stress condition can be understood as the magnitude of the stress received by each cross-section of the target pipeline.

[0109] Specifically, the processor can determine the stress condition received by the target pipeline under different cross-sections according to the mechanical response state.

[0110] S210. Based on the stress condition, determine the high-risk areas in the target pipeline that are threatened by settlement.

[0111] In this embodiment, the high-risk area can be understood as the pipeline area where serious settlement will pose a risk of pipeline damage. For example, the 50m position in area a is a high-risk area.

[0112] Specifically, the processor can determine the high-risk areas in the target pipeline that are threatened by settlement through a preset stress threshold or other means according to the stress condition.

[0113] S211. Based on the high-risk areas, generate a warning message for the target pipeline and give a warning.

[0114] Specifically, the processor can jointly generate a warning message for the target pipeline based on the high-risk areas and the stress condition and give a warning.

[0115] The technical solution of the embodiment of the present invention determines a matching vertical external force load strategy through the pipe burial depth during the construction of the target pipeline, so as to make the determination of the vertical external force load more accurate and in line with the actual situation. The load to be corrected is determined through the relative settlement amount between the pipe and the soil and the vertical external force load strategy. Based on the current soil mechanics parameters and the biaxial compression simulation experiment of the soil mass, the microscopic parameters of soil particles are determined, and then the load to be corrected is corrected through the microscopic parameters of soil particles to obtain the vertical external force load. The discreteness of the soil mass and the load change of the vertical external force of different pipeline sections are considered to determine the vertical external force load that most conforms to the actual soil mass situation. By applying the vertical external force load to the settlement area in the constructed pipeline model, the actual soil settlement situation is accurately simulated, and the soil mass part in the non-settlement area of the pipeline model is simulated by the soil spring model, accurately restoring the environmental situation of the target pipeline. By running the model to obtain the mechanical response state, the calculation and evaluation efficiency of the stress condition of the buried pipeline under the action of formation settlement are greatly improved, which is of great significance for the safety determination of the buried pipeline. Based on the mechanical response state, the high-risk area of the target pipeline is determined, realizing the accurate positioning of the settlement threat and giving an early warning, so that relevant personnel can maintain the pipeline, thereby ensuring the safety of the pipeline.
