[0001] The present invention relates to the field of pile foundation detection, and in particular to a pile foundation static load detection method, system and terminal. Background Art

[0002] As the foundation of a building, the bearing capacity and stability of the pile foundation are directly related to the safety of the building. Static load testing of pile foundation is one of the important methods to determine the bearing capacity of pile foundation. By applying vertical pressure step by step on the top of the pile and observing the settlement of the top of the pile over time, the vertical compressive ultimate bearing capacity of a single pile can be determined.

[0003] Currently, at the site of static load testing of pile foundations, workers need to remain highly focused at all times, closely monitor the loading process, and take corresponding actions for a series of events that occur during the testing process.

[0004] Regarding the above-mentioned content, the on-site inspection process relies on a large amount of manual operations, and the staff need to take care of multiple tasks at the same time. This not only places great demands on manpower, but also easily reduces the inspection efficiency due to distraction, which needs to be improved. Summary of the invention

[0005] In order to improve detection efficiency, the present invention provides a pile foundation static load detection method, system and terminal.

[0006] In a first aspect, the present invention provides a pile foundation static load detection method, which adopts the following technical solution: A pile foundation static load detection method, comprising: Obtaining regional image information of a preset test area; Determine the detection position and detection pile model according to the regional image information, the preset detection pile features and the reference objects; Determine the test strength value and initial strength value according to the test pile model; Determine a reference pressure value according to an initial force value and a detection force value; Determine the pressure value according to the initial force value and the reference pressure value; Based on the detection position, a preset detection device is controlled to perform downward pressure detection on a preset detection pile with an initial force value, and the pile top settlement of the detection pile is obtained; After a preset reference intermittent time, the detection device is controlled to perform downward pressure detection on the detection pile with a pressure value, and the pressure settlement amount of the detection pile is obtained; The quotient between the pile top settlement and the pressurized settlement is calculated as the settlement difference value, and when the settlement difference value exceeds the preset benchmark difference value, an abnormality prompt of the detection pile is reported.

[0007] By adopting the above technical solution, the regional image information of the test area is first obtained, and the detection position and the detection pile model are accurately determined based on this information, the detection pile characteristics and the reference objects. Subsequently, the detection force value and the initial force value are clarified according to the detection pile model, and then the reference pressure value and the pressure force value are obtained. Next, at the detection position, the detection pile is first pressed down with the initial force value to obtain the settlement of the pile top. After the reference interval time, it is pressed down again with the pressure force value to obtain the pressurized settlement. The settlement difference value is obtained by calculating the quotient of the two settlement amounts. Once the value exceeds the reference difference value, the detection pile abnormality prompt is reported, thereby improving the detection efficiency of the pile foundation detection.

[0008] Optionally, a flatness correction method is also included: When the settlement difference value exceeds the preset reference difference value, the area flatness of the test area is obtained; When the regional flatness is lower than the preset reference flatness, the difference between the regional flatness and the reference flatness is calculated as the flatness difference value; Match the settlement correction value from the preset detection database according to the flatness difference value; Determine the corrected pile top settlement and corrected pressurized settlement based on the settlement correction value, pile top settlement and pressurized settlement; The quotient between the corrected pile top settlement and the corrected pressurized settlement is calculated as the corrected settlement difference value, and when the corrected settlement difference value exceeds the benchmark difference value, an abnormality prompt of the test pile is reported.

[0009] By adopting the above technical solution, after the abnormality is found in the initial detection, the regional flatness factor is introduced for secondary analysis. The condition of the test pile is judged more accurately by correcting the settlement, eliminating the interference of the uneven test area on the test results, and effectively improving the accuracy and reliability of the detection.

[0010] Optionally, the flatness correction method also includes: When the corrected settlement difference value exceeds the reference difference value, the current angle value of the detection pile is obtained; When the current angle value is inconsistent with the preset reference angle value, the difference between the current angle value and the reference angle value is calculated as the angle difference value; Determine the tightness of the land according to the angle difference value and the initial force value; Determine the looseness and settlement correction value based on the land looseness value and the preset benchmark looseness range; Determine the loose-tight pile top settlement and loose-tight pressurized settlement based on the loose-tight settlement correction value, pile top settlement and pressurized settlement; The quotient between the loose and tight pile top settlement and the loose and tight pressurized settlement is calculated as the loose and tight settlement difference value, and when the loose and tight settlement difference value exceeds the benchmark difference value, an abnormality prompt of the detection pile is reported.

[0011] By adopting the above technical solution, on the basis of considering the impact of flatness on the test results, the angle of the test pile is further analyzed to determine the effect of the tightness of the land on the settlement, and the settlement is corrected again and the condition of the test pile is evaluated. The multi-dimensional and refined testing process can more comprehensively and accurately detect abnormal factors of the test pile, effectively improve the accuracy of pile foundation static load testing, ensure the quality of pile foundation engineering, and ensure the stability of the foundation of the construction project.

[0012] Optionally, land tightness adjustment methods are also included: Determine the required land area based on the test pile model and test strength value; When the land tightness value exceeds the preset tighter reference value, the loosening area is determined according to the current angle value and the required land area; Determine the land looseness adjustment value based on the land looseness value, the tighter reference value and the detection strength value; Determine the insertion depth and insertion position according to the land loosening value and loosening area; Determine the post-insertion compaction parameters based on the insertion depth, insertion position and soil loosening value; Controlling a preset land adjustment device to loosen the land at the insertion position according to the insertion depth, and after the loosening, compacting the land according to the post-insertion compaction parameters; When the land tightness value is lower than the preset looser reference value, the land tightening area and land compaction parameters are determined according to the required land area, the land tightness value and the looser reference value; The preset land adjustment device is controlled to perform land compaction and tightening in the land tightening area according to the land compaction parameters.

[0013] By adopting the above technical solution, the land can be loosened or tightened in a targeted manner according to the relevant parameters of the test piles and the actual tightness of the land, ensuring that the land conditions meet the detection requirements of the test piles, optimizing the detection environment, and further improving the accuracy and reliability of pile foundation static load detection.

[0014] Optionally, crack correction methods are also included: When the settlement difference value exceeds a preset reference difference value, a preset clamping device is controlled to clamp the detection pile to a preset detection area, and detection image information of the detection pile is obtained; Determining whether the detected image information contains a preset crack feature; When the detection image information contains crack features, the initial position of the crack is determined according to the detection image information, the crack features, the detection pile model and the preset reference object; According to the initial position of the crack, a preset crack detection device is controlled to perform crack detection on the detection pile and obtain crack parameters; Determine the crack settlement difference value based on crack parameters, pile top settlement and pressurized settlement; When the crack settlement difference value exceeds the benchmark difference value, an abnormal detection pile prompt is reported.

[0015] By adopting the above technical solutions, the troubleshooting process for abnormal conditions of the test piles has been further refined. Based on the abnormal settlement difference, the possible crack problems of the test piles are deeply explored. By analyzing the crack location and parameters, combined with the settlement data, the abnormal conditions of the test piles can be judged more comprehensively and accurately, providing a richer and more reliable basis for the quality inspection of pile foundation projects, helping to timely discover and solve potential pile foundation quality risks and ensure the safety and stability of the project.

[0016] Optionally, crack verification methods are also included: When the crack settlement difference value exceeds the reference difference value, obtaining internal image information of the preset piling area; Determine whether the internal image information contains preset foreign body features; When the internal image information contains features of foreign matter, the location and size of the foreign matter are determined based on the internal image information, the features of the foreign matter, the preset area size, and the reference object; Determine whether the position of the foreign body is consistent with the initial position of the crack; When the position of the foreign body is inconsistent with the initial position of the crack, an abnormality prompt of the detection pile is reported; When the position of the foreign body is consistent with the initial position of the crack, the benchmark crack parameters are determined according to the size of the foreign body, the initial force value, the pressure value and the test pile model; When the benchmark crack parameters are inconsistent with the crack parameters, an abnormality prompt of the detection pile is reported.

[0017] By adopting the above technical solution, when the difference in crack settlement exceeds the benchmark, it means that the test pile may be abnormal. At this time, the internal image of the piling area is obtained. If there are foreign body features in the image, the location and size of the foreign body are determined in combination with relevant information. The location of the foreign body is compared with the initial position of the crack. If they are inconsistent, an abnormality is reported. If they are consistent, the benchmark crack parameters are determined based on the size of the foreign body, the force value and the test pile model, and compared with the actual crack parameters. If they are inconsistent, an abnormality is also reported. In this way, the crack abnormality of the test pile is verified from the perspective of foreign bodies, and multi-dimensional analysis and judgment are performed to accurately locate the cause of the abnormality, avoid misjudgment, and improve the accuracy and reliability of detection.

[0019] By adopting the above technical solution, the verification process for abnormal cracks in the detection piles is further refined. Through in-depth analysis of crack parameters and multi-dimensional troubleshooting of abnormalities, the condition of the detection piles can be accurately judged, effectively improving the accuracy of pile foundation static load testing.

[0020] Optionally, also include the algorithm formula for calculating the insertion depth: D=k1*V+k2*√A, where D is the insertion depth, V is the land loosening value, A is the loosening area, and k1 and k2 are influence coefficients.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] The embodiment of the present application discloses a pile foundation static load detection method.

[0027] Reference Figure 1 , a pile foundation static load detection method comprises the following steps: Step 100: Obtain regional image information of a preset test area.

[0028] The test area refers to the area used for static load testing of the test pile. The regional image information refers to the image of the test pile contained in the test area. The regional image information is obtained by taking a photo with a camera. The test area is set in advance by a person skilled in the art and will not be described in detail here. The test pile refers to the pile body used for various tests on the pile foundation.

[0029] Step 101: Determine the detection pile model according to the regional image information and preset detection pile features.

[0030] The detection pile feature refers to the outer contour of the detection pile. The detection pile feature is set in advance by a person skilled in the art and will not be elaborated here. The detection pile model refers to the number used to identify and distinguish detection piles of different types, specifications and performances, which includes the material, shape and size of the detection pile. The detection pile model corresponding to the detection pile feature in the regional image information can be identified through the preset model database, and the model database contains the correspondence between the regional image information, the detection pile feature and the detection pile model. The model database is an artificially set database and will not be elaborated here.

[0031] Step 102: Determine the detection position according to the regional image information, the detection pile features and the preset reference objects.

[0032] The reference object refers to an object used to assist in measuring the position of the detection pile and other features that require auxiliary measurement. The size and position of the reference object are set in advance by a person skilled in the art and will not be described in detail here. The detection position refers to the position of the detection pile in the test area. First, the position of the detection pile feature in the image can be known through the regional image information. Then, by comparing the position and size of the detection pile feature and the reference object in the image, as well as the actual position and size of the reference object, the detection position can be obtained.

[0033] Step 103: Determine the detection force value and the initial force value according to the detection pile model.

[0034] The detection force value refers to the maximum force value that needs to be reached when testing the pile corresponding to the detection pile model. The initial force value refers to the starting value for applying force when testing the detection pile. The detection force value and initial force value corresponding to the detection pile model can be matched through the preset detection database, which contains the corresponding relationship between the detection pile model, the detection force value and the initial force value. The detection database is a manually set database and will not be elaborated here.

[0035] Step 104: Determine a reference pressure value according to the initial force value and the detected force value.

[0036] The reference pressure value refers to the value that needs to be increased when continuing to test the test pile after testing it with the initial force value. The reference pressure value corresponding to the initial force value and the test force value can be matched through the test database, which contains the corresponding relationship between the initial force value, the test force value and the reference pressure value.

[0037] Step 105: Determine the pressure value according to the initial pressure value and the reference pressure value.

[0038] The pressure value refers to the force value after the test pile is tested with the initial force value and then the test continues. The pressure value can be obtained by calculating the sum of the initial force value and the reference pressure value.

[0039] Step 106: Based on the detection position, a preset detection device is controlled to perform downward pressure detection on a preset detection pile with an initial force value, and the pile top settlement of the detection pile is obtained.

[0040] The detection device refers to a device used to perform static load detection on the detection pile. The pile top settlement refers to the displacement of the detection pile when the detection device presses down on the detection pile with the initial force value. The pile top settlement is measured and obtained by the displacement sensor preset on the detection pile.

[0041] The control detection device performs downward pressure detection on the detection pile at the detection position with the initial force value, and obtains the pile top settlement of the detection pile for subsequent steps.

[0042] Step 107: Based on a preset reference intermittent time, the detection device is controlled to perform downward pressure detection on the detection pile with a pressure value, and the pressurized settlement amount of the detection pile is obtained.

[0043] The reference intermittent time refers to the length of time after the detection pile is tested with the initial force value and before the next test. The reference intermittent time is set in advance by those skilled in the art and will not be described in detail here. The pressurized settlement refers to the displacement of the detection pile when the detection device presses down on the detection pile with the pressurized force value and the detection pile continues to sink in the vertical direction. The pressurized settlement is measured and obtained by the displacement sensor on the detection pile.

[0044] Based on the reference intermittent time, the detection device is controlled to perform downward pressure detection on the detection pile with the pressure value, and after the detection, the pressurized settlement of the detection pile is obtained for subsequent steps.

[0045] Step 108: Calculate the quotient between the pile top settlement and the pressurized settlement as the settlement difference value, and report an abnormality prompt of the detection pile when the settlement difference value exceeds a preset reference difference value.

[0046] The settlement difference value refers to the difference multiple between the settlement amounts of two tests. The settlement difference value can be obtained by calculating the quotient between the settlement amount at the top of the pile and the pressurized settlement amount. The reference difference value refers to the maximum value allowed for the settlement difference value. The abnormality prompt of the test pile refers to the prompt when the test pile currently being tested is unqualified. The reference difference value and the abnormality prompt of the test pile are both set in advance by those skilled in the art and will not be elaborated here.

[0047] The calculated settlement difference value is compared with the benchmark difference value. When the settlement difference value exceeds the benchmark difference value, it means that the current test pile is unqualified and the test pile abnormality prompt needs to be reported.

[0048] When the settlement difference value does not exceed the reference difference value, it means that the test can continue, and the pressure value obtained in step 105 is defined as a new initial force value, and then the new initial force value is added to the reference pressure value to obtain a new pressure value, and subsequent steps 106 to 108 are repeated until the new pressure value is consistent with the test force value, and the test is completed.

[0049] Reference Figure 2 , the flatness correction method includes the following steps: Step 200: When the settlement difference value exceeds a preset reference difference value, obtain the area flatness of the test area.

[0050] Regional flatness refers to the flatness of the ground in the test area in the horizontal direction. Regional flatness is obtained through a preset laser scanner. When the settlement difference value exceeds the benchmark difference value, in order to avoid data deviation due to terrain problems, the regional flatness of the test area needs to be obtained for subsequent steps.

[0051] Step 201: When the regional flatness is lower than a preset reference flatness, a difference between the regional flatness and the reference flatness is calculated as a flatness difference value.

[0052] The reference flatness refers to the value that the flatness of the test area should reach. The reference flatness is set in advance by a person skilled in the art and will not be described in detail here. The flatness difference value refers to the deviation value between the regional flatness and the reference flatness. The flatness difference value can be obtained by calculating the difference between the regional flatness and the reference flatness.

[0053] When the flatness of the area is lower than the reference flatness, it means that the ground in the test area is too uneven and the flatness difference value needs to be calculated for subsequent steps.

[0054] Step 202: Matching a settlement correction value from a preset detection database according to the flatness difference value.

[0055] The settlement correction value refers to the value used to correct the pile top settlement and pressurized settlement due to the influence of terrain factors. The settlement correction value corresponding to the flatness difference value can be matched through the detection database, which contains the corresponding relationship between the flatness difference value and the settlement correction value.

[0056] Step 203: Determine the corrected pile top settlement and the corrected pressurized settlement according to the settlement correction value, the pile top settlement and the pressurized settlement.

[0057] The corrected pile top settlement refers to the pile top settlement after correction due to the influence of terrain factors. The corrected pressurized settlement refers to the pressurized settlement after correction due to the influence of terrain factors. The preset correction database can be used to match the settlement correction value, pile top settlement and the corrected pile top settlement and the corrected pressurized settlement corresponding to the pressurized settlement, which includes the correspondence between the settlement correction value, pile top settlement, pressurized settlement, corrected pile top settlement and corrected pressurized settlement. The correction database is an artificially set database and will not be elaborated here.

[0058] Step 204: Calculate the quotient between the corrected pile top settlement and the corrected pressurized settlement as the corrected settlement difference value, and report an abnormality prompt of the detection pile when the corrected settlement difference value exceeds the reference difference value.

[0059] The corrected settlement difference value refers to the difference multiple between the corrected pile top settlement and the corrected pressurized settlement. The corrected settlement difference value can be obtained by calculating the quotient between the corrected pile top settlement and the corrected pressurized settlement. When the corrected settlement difference value exceeds the benchmark difference value, it means that the current test pile is unqualified and the abnormality of the test pile needs to be reported.

[0060] Reference Figure 3 The flatness correction method also includes the following steps: Step 300: When the corrected settlement difference value exceeds the reference difference value, the current angle value of the detection pile is obtained.

[0061] The current angle value refers to the angle value of the detection pile relative to the horizontal direction. The current angle value is measured by a level meter. When the corrected settlement difference value exceeds the reference difference value, the current angle value of the detection pile needs to be obtained for subsequent steps.

[0062] Step 301: When the current angle value is inconsistent with the preset reference angle value, the difference between the current angle value and the reference angle value is calculated as the angle difference value.

[0063] The reference angle value refers to the angle value that the detection pile should currently be at. The reference angle value is set in advance by a person skilled in the art and will not be described in detail here. The angle difference value refers to the difference between the current angle value of the detection pile and the reference angle value. The angle difference value can be obtained by calculating the difference between the current angle value and the reference angle value.

[0064] When the current angle value is inconsistent with the reference angle value, it means that the current angle value of the detection pile is abnormal, and the angle difference value needs to be calculated for subsequent steps.

[0065] Step 302: Determine the ground tightness value according to the angle difference value and the initial force value.

[0066] The land tightness value refers to the quantitative value of the compactness or looseness of the land in the test area. The land tightness value corresponding to the angle difference value and the initial force value can be matched through the preset tightness database, which contains the corresponding relationship between the angle difference value and the initial force value and the land tightness value. The tightness database is a manually set database and will not be described here.

[0067] Step 303: Determine a looseness and settlement correction value according to the looseness value of the land and a preset reference looseness range.

[0068] The reference tightness interval refers to the interval into which the tightness value of the land in the test area should fall. The reference tightness interval is set in advance by a person skilled in the art and will not be elaborated here. The tightness settlement correction value refers to the value used to correct the pile top settlement and pressurized settlement due to the influence of the land tightness factor. The looseness settlement correction value corresponding to the land tightness value and the reference tightness interval can be matched by the detection database, which includes the correspondence between the land tightness value and the reference tightness interval and the tightness settlement correction value.

[0069] Step 304: Determine the loose-tight pile top settlement and the loose-tight pressurized settlement according to the loose-tight settlement correction value, the pile top settlement and the pressurized settlement.

[0070] The loose-tight pile top settlement refers to the pile top settlement corrected due to the looseness of the soil. The loose-tight pressurized settlement refers to the pressurized settlement corrected due to the looseness of the soil. The correction database can be used to match the loose-tight settlement correction value, pile top settlement, and pressurized settlement corresponding to the loose-tight pile top settlement and loose-tight pressurized settlement, which includes the correspondence between the loose-tight settlement correction value, pile top settlement, pressurized settlement, loose-tight pile top settlement, and loose-tight pressurized settlement.

[0071] Step 305: Calculate the quotient between the loose-tight pile top settlement and the loose-tight pressurized settlement as the loose-tight settlement difference value, and report an abnormality prompt of the detection pile when the loose-tight settlement difference value exceeds the reference difference value.

[0072] The loose-tight settlement difference value refers to the difference multiple between the loose-tight pile top settlement and the loose-tight pressurized settlement. The loose-tight settlement difference value can be obtained by calculating the quotient between the loose-tight pile top settlement and the loose-tight pressurized settlement. And when the loose-tight settlement difference value exceeds the benchmark difference value, it means that the current test pile is unqualified and the test pile abnormality prompt needs to be reported.

[0073] Reference Figure 4 The land looseness adjustment method includes the following steps: Step 400: Determine the required land area according to the detection pile model and the detection strength value.

[0074] The required land area refers to the area of ​​land required to test the detection pile. The preset area database can be used to match the required land area corresponding to the detection pile model and the detection strength value, which contains the corresponding relationship between the detection pile model and the detection strength value and the required land area. The area database is a manually set database and will not be elaborated here.

[0075] Step 401: When the land tightness value exceeds a preset tighter reference value, the loosening area is determined according to the current angle value and the required land area.

[0076] The tighter baseline value refers to the quantitative value corresponding to the land in the test area that is too tight. The tighter baseline value is the maximum value of the baseline tightness interval. The specific value is set in advance by a technician in this field and will not be described in detail here. The loosening area refers to the area where the tight land needs to be loosened. The preset loosening database can be used to match the current angle value and the required land area to the loosening area, which includes the corresponding relationship between the current angle value and the required land area and the loosening area. The loosening database is an artificially set database and will not be described in detail here.

[0077] When the land tightness value exceeds the tighter benchmark value, it means that the land is too tight and the loosening area needs to be matched first for subsequent steps.

[0078] Step 402: Determine the soil looseness adjustment value according to the soil tightness value, the tighter reference value and the detection strength value.

[0079] The land loosening value refers to the value required to adjust the tightness of the land in the test area to below the tighter reference value. The land loosening value corresponding to the land looseness value, the tighter reference value and the detection strength value can be matched through the loosening database, which contains the corresponding relationship between the land looseness value, the tighter reference value, the detection strength value and the land loosening value.

[0080] Step 403: Determine the insertion depth and insertion position according to the land loosening value and the loosening area.

[0081] The insertion depth refers to the depth of the insertion into the land when loosening the land. The insertion position refers to the position of the insertion into the land when loosening the land. The insertion depth and insertion position corresponding to the land loosening value and the loosening area can be matched through the preset insertion database, which includes the correspondence between the land loosening value, the loosening area and the insertion position, and the algorithm formula for calculating the insertion depth: D=k1*V+k2*√A, where D is the insertion depth, V is the land loosening value, A is the loosening area, and k1 and k2 are influence coefficients. The insertion database is a manually set database and will not be elaborated here. k1 and k2 are set in advance by those skilled in the art and will not be elaborated here.

[0082] Step 404: Determine post-insertion compaction parameters according to the insertion depth, insertion position, and soil loosening value.

[0083] The post-insertion compaction parameter refers to the force value that needs to be compacted again after the land is inserted and loosened. The preset compaction database can match the post-insertion compaction parameters corresponding to the insertion depth, insertion position and land loosening value. It contains the corresponding relationship between the insertion depth, insertion position, land loosening value and post-insertion compaction parameters. The compaction database is a manually set database and will not be described here.

[0084] Step 405: Control the preset land adjustment device to loosen the land at the insertion position according to the insertion depth, and after the loosening, compact the land according to the post-insertion compaction parameters.

[0085] The land adjustment device refers to a device used to adjust the tightness of the land. The land adjustment device is controlled to loosen the land at the insertion position according to the insertion depth, and after loosening, the land is compacted according to the post-insertion compaction parameters to complete the adjustment of the tightness of the land.

[0086] Step 406: When the land tightness value is lower than the preset looser reference value, determine the land tightening area and land compaction parameters according to the required land area, the land tightness value and the looser reference value.

[0087] The looser baseline value refers to the quantitative value corresponding to the land in the test area that is too loose. The looser baseline value is the minimum value of the baseline tightness interval. The specific value is set in advance by a technician in this field and will not be elaborated here. The land tightening area refers to the area where the too loose land needs to be compacted and tightened. The land compaction parameter refers to the force value that needs to be compacted and tightened for the too loose land. The preset tightening database can match the required land area, land tightness value, and land tightening area and land compaction parameters corresponding to the looser baseline value. It contains the corresponding relationship between the required land area, land tightness value, looser baseline value, land tightening area and land compaction parameters. The tightening database is an artificially set database and will not be elaborated here.

[0088] When the land tightness value is lower than the looser baseline value, it means that the land is too loose and it is necessary to match the land tightening area and land compaction parameters for subsequent steps.

[0089] Step 407: Control the preset land adjustment device to perform land compaction and tightening on the land tightening area with the land compaction parameters.

[0090] The land adjustment device is controlled to compact and tighten the land in the land adjustment area according to the land compaction parameters, so as to complete the adjustment of the land tightness.

[0091] Reference Figure 5, the crack correction method includes the following steps: Step 500: When the settlement difference value exceeds a preset reference difference value, a preset clamping device is controlled to clamp the detection pile to a preset detection area, and detection image information of the detection pile is obtained.

[0092] The clamping device refers to a device used to clamp the abnormal detection pile to the detection area. The detection area refers to the area used to detect the abnormal detection pile. The detection image information refers to the image of the detection pile in the detection area. The detection image information is obtained by taking a picture with a camera.

[0093] When the settlement difference value exceeds the reference difference value, it is necessary to control the clamping device to clamp the detection pile into the detection area and obtain the detection image information of the detection pile for subsequent steps.

[0094] Step 501: Determine whether the detected image information contains preset crack features.

[0095] The crack feature refers to the appearance feature when there is a crack on the test pile. The crack feature is set in advance by a person skilled in the art and will not be described in detail here. By judging whether the crack feature is included in the test image information, it is known whether there is a crack on the test pile, and the settlement difference value can be further verified.

[0096] Step 502: When the detection image information contains crack features, the initial position of the crack is determined according to the detection image information, the crack features, the detection pile model and a preset reference object.

[0097] The initial crack position refers to the position where the crack first appears on the test pile. First, the position of the crack feature in the image is determined by detecting the image information. Then, the position and size of the crack feature in the image are compared with the position and size of the reference object, and the test position is obtained by combining the test pile model, the actual position and size of the reference object.

[0098] When the detection image information contains crack features, it means that there are cracks on the detection pile, and the initial position of the crack needs to be determined first for subsequent steps.

[0099] When the detection image information does not contain crack features, it means that there is no crack on the detection pile, and the crack detection is completed.

[0100] Step 503: Control a preset crack detection device to perform crack detection on the detection pile according to the initial crack position, and obtain crack parameters.

[0101] The crack detection device refers to a device for detecting the depth and size of cracks on the detection pile. Crack parameters refer to the depth and size of cracks on the detection pile. The crack parameters can be obtained by calling the data storage terminal in the crack detection device. When the crack detection device performs crack detection on the detection pile, the detection results will be stored in the data storage terminal. The data storage terminal is set in advance by a person skilled in the art and will not be described in detail here.

[0102] The crack detection device is controlled to perform crack detection on the initial position of the crack on the detection pile, and then the crack parameters are obtained for subsequent steps.

[0103] Step 504: Determine the crack settlement difference value according to the crack parameters, the pile top settlement and the pressurized settlement.

[0104] The crack settlement difference value refers to the difference multiple between the crack pile top settlement and the crack pressurized settlement. The crack pile top settlement refers to the pile top settlement after correction due to the influence of the factors causing cracks in the test pile. The crack pressurized settlement refers to the pressurized settlement after correction due to the influence of the factors causing cracks in the test pile. The crack pile top settlement and crack pressurized settlement corresponding to the crack parameters, pile top settlement and pressurized settlement can be matched through the correction database, which includes the corresponding relationship between the crack parameters, pile top settlement, pressurized settlement, crack pile top settlement and crack pressurized settlement. The crack settlement difference value can be obtained by calculating the quotient between the crack pile top settlement and the crack pressurized settlement.

[0105] Step 505: When the crack settlement difference value exceeds the reference difference value, an abnormality prompt of the detection pile is reported.

[0106] When the crack settlement difference value exceeds the benchmark difference value, it means that the current test pile is unqualified and the test pile abnormality prompt needs to be reported.

[0107] Reference Figure 6 , the crack verification method includes the following steps: Step 600: When the crack settlement difference value exceeds the reference difference value, internal image information of a preset piling area is obtained.

[0108] The piling area refers to the area in the test area for placing the test piles. The piling area is set in advance by those skilled in the art and will not be described in detail here. Since a pit is formed in the piling area when the test pile is tested, the internal image information refers to the image inside the pit in the piling area. The internal image information is obtained by taking pictures with a camera.

[0109] When the crack settlement difference value exceeds the benchmark difference value, it is necessary to obtain the internal image information of the piling area for subsequent steps.

[0110] Step 601: Determine whether the internal image information contains preset foreign body features.

[0111] Foreign body features refer to the features when objects other than soil appear in the pit. Foreign body features are set in advance by technicians in this field and will not be described here. By judging whether the internal image information contains foreign body features, it is known whether there are foreign bodies in the pit, and then the cause of cracks in the test pile can be determined.

[0112] Step 602: When the internal image information contains foreign body features, determine the location and size of the foreign body according to the internal image information, the foreign body features, a preset area size, and a reference object.

[0113] The area size refers to the size of the piling area. The area size is set in advance by those skilled in the art and will not be described in detail here. The foreign body position refers to the position of the foreign body feature in the pit. The foreign body size refers to the size of the foreign body feature. The preset image recognition library can match the internal image information, foreign body features, area size and the foreign body position and foreign body size corresponding to the reference object, which contains the corresponding relationship between the internal image information, foreign body features, area size, reference object, foreign body position and foreign body size. The image recognition library is a manually set database and will not be described in detail here. When the internal image information contains foreign body features, it means that there is a foreign body inside the pit, and the foreign body position and foreign body size must be matched first for subsequent steps.

[0114] When the internal image information does not contain foreign body features, it means that there is no foreign body in the pit and the foreign body detection is completed.

[0115] Step 603: Determine whether the position of the foreign matter is consistent with the initial position of the crack.

[0116] By judging whether the position of the foreign body is consistent with the initial position of the crack, it can be known whether the cause of the crack in the test pile is the foreign body.

[0117] Step 604: When the position of the foreign body is inconsistent with the initial position of the crack, an abnormality prompt of the detection pile is reported.

[0118] When the position of the foreign body is inconsistent with the initial position of the crack, it means that the cause of the crack in the test pile is not the foreign body, which further indicates that there was an abnormality in the test pile beforehand, and the abnormality prompt of the test pile needs to be reported.

[0119] Step 605: When the position of the foreign body is consistent with the initial position of the crack, the reference crack parameters are determined according to the size of the foreign body, the initial force value, the pressure value and the test pile model.

[0120] The reference crack parameters refer to the depth and size of the cracks on the test pile when the test pile is tested with the initial force value and the pressure force value. The preset crack database can match the reference crack parameters corresponding to the foreign body size, initial force value, pressure force value and test pile model, which contains the correspondence between the foreign body size, initial force value, pressure force value, test pile model and reference crack parameters. The crack database is a manually set database and will not be described in detail here.

[0121] When the position of the foreign body is consistent with the initial position of the crack, it means that the cause of the crack in the test pile is the foreign body, and the benchmark crack parameters need to be matched first for subsequent steps.

[0122] Step 606: When the reference crack parameter is inconsistent with the crack parameter, an abnormality prompt of the detection pile is reported.

[0123] When the benchmark crack parameters are inconsistent with the crack parameters, it means that the cause of the cracks in the test pile is not only foreign matter, but also that there is an abnormality in the test pile, and the abnormality prompt of the test pile needs to be reported.

[0124] Reference Figure 7 , the crack verification method also includes the following steps: Step 700: When the reference crack parameter and the crack parameter are inconsistent, determine the crack difference parameter according to the reference crack parameter and the crack parameter.

[0125] The crack difference parameter refers to the difference between the depth and size of the crack on the test pile and the actual depth and size of the crack on the test pile. The crack difference parameter corresponding to the reference crack parameter and the crack parameter can be matched through the crack database, which includes the corresponding relationship between the reference crack parameter and the crack parameter and the crack difference parameter.

[0126] When the reference crack parameters are inconsistent with the crack parameters, the crack difference parameters must be matched first for subsequent steps.

[0127] Step 701: matching a reference difference parameter interval from a preset crack database according to an initial force value, a pressing force value, a foreign body size, and a preset initial crack parameter interval.

[0128] The initial crack parameter interval refers to the interval of the depth and size of the crack when cracks already exist inside the detection pile. The initial crack parameter interval is set in advance by a person skilled in the art and will not be described in detail here. The benchmark difference parameter interval refers to the interval into which the crack difference parameter between the benchmark crack parameter and the crack parameter should fall when cracks already exist inside the detection pile. The initial force value, the applied force value, the foreign body size, and the benchmark difference parameter interval corresponding to the preset initial crack parameter interval can be matched through the crack database, which includes the correspondence between the initial force value, the applied force value, the foreign body size, the initial crack parameter interval, and the benchmark difference parameter interval.

[0129] Step 702: When the crack difference parameter does not fall within the reference difference parameter interval, an abnormality prompt of the detection pile is reported.

[0130] If the crack difference parameter does not fall within the benchmark difference parameter range, it means that the crack of the test pile is abnormal and the test pile abnormality prompt needs to be reported.

[0131] Step 703: When the crack difference parameter falls into the reference difference parameter interval, a correction crack parameter is determined according to the crack difference parameter.

[0132] The crack correction parameter refers to the value used to correct the pile top settlement and pressurized settlement due to the influence of crack difference factors.

[0133] If the crack difference parameter falls within the benchmark difference parameter range, it means that there is no abnormality in the crack of the test pile, and the corrective crack parameters need to be matched first for subsequent steps.

[0134] Step 704: Determine the corrected crack difference value according to the corrected crack parameters, the pile top settlement and the pressurized settlement.

[0135] The corrected crack difference value refers to the difference multiple between the pile top settlement and the pressurized settlement after correction due to the crack difference factor. The corrected crack difference value corresponding to the corrected crack parameters, pile top settlement and pressurized settlement can be matched through the correction database, which includes the corresponding relationship between the corrected crack difference value, pile top settlement, pressurized settlement and the corrected crack difference value.

[0136] Step 705: When the corrected crack difference value exceeds the reference difference value, an abnormality prompt of the detection pile is reported.

[0137] When the corrected crack difference value exceeds the benchmark difference value, it means that the current test pile is unqualified and the test pile abnormality prompt needs to be reported.
