Technical Field

[0001] This invention belongs to the field of core drilling testing technology, and more specifically, relates to a core drilling testing system and testing method for pile foundations. Background Technology

[0002] Core drilling is used to verify the location, characteristics, and sediment thickness of pile foundation defects by examining drilled cores, thereby determining the integrity of the pile and the thickness of the sediment. In geotechnical engineering and building foundation pile testing, after drilling is completed, the core samples should be stored in a core sample box and marked according to the drilling sequence for subsequent testing and analysis of pile quality and other information.

[0003] In existing technologies, core samples need to be removed from the sample box and then tested by a testing device. This process is cumbersome and can easily damage the core sample during transfer, leading to incorrect numbering and affecting the accuracy and reliability of the test. Summary of the Invention

[0009] The detection component includes a first collector disposed on one side of the collection slot and a controller electrically connected to the first collector;

[0010] In the radial direction of the core sample storage, the holding hole, the collection slot, and the information collection end of the first collector corresponding to the drill core to be tested are sequentially aligned; the first collector is used to collect the surface information of the drill core through the collection slot, and the controller is able to receive the surface information collected by the first collector.

[0011] In conjunction with the first aspect, in one possible implementation, the core sample storage device includes:

[0012] The core sample box has a first sampling groove that runs radially through its wall.

[0013] The main rotating module is located inside the core sample box; multiple holding holes are spaced apart along its circumference inside the main rotating module; the main rotating module has a detection position; the main rotating module is also provided with a second collection groove that corresponds to and communicates with each of the multiple holding holes, and each of the second collection grooves extends to the outer peripheral wall of the main rotating module.

[0014] Each of the holding holes is provided with a corresponding sub-rotor, and the power output end of the first driving member is connected to the extension end of the sub-rotor that has rotated to the detection position, so as to drive the sub-rotor and the corresponding drill core to rotate; in the radial direction of the core sample storage, the second collection slot, the first collection slot, and the collection end of the first collector that have rotated to the detection position correspond to each other.

[0015] In some embodiments, the core sample storage device further includes:

[0016] The lower box is supported at the bottom of the main rotating module and is fixedly connected to the core sample box; the lower box is provided with a second driving component, which is poweredly connected to the main rotating module to drive the main rotating module to rotate, thereby causing the multiple holding holes to rotate sequentially to the detection position; the lower box also contains the first driving component.

[0017] In some embodiments, the main rotation module includes:

[0018] The main turntable is located at the bottom of the core sample box and is poweredly connected to the second driving component;

[0019] An installation mold is connected to the top of the main turntable; the installation mold is provided with the container hole and the second collection slot.

[0020] Each of the sub-turntables is positioned on the main turntable, with the upper end of each sub-turntable extending upward into the container hole and the lower end extending downward past the main turntable.

[0021] For example, the mounting mold has a ring structure, and the main turntable is provided with a ring-shaped limiting hole adapted to the ring structure, and the bottom of the mounting mold is limited within the ring-shaped limiting hole;

[0022] The bottom of the annular limiting hole is provided with multiple downward-through limiting step holes, and the multiple holding holes and the multiple limiting step holes correspond one-to-one. The sub-turntable is limited within the corresponding limiting step hole.

[0024] A second collector is provided within the annular inner enclosure area of ​​the main rotating module; the second collector is electrically connected to the controller;

[0025] In the radial direction of the mounting mold, the collecting end of the second collector, the third collecting groove, and the holding hole correspond sequentially.

[0026] In some embodiments, the bottom of the sub-rotor is provided with a connecting boss, which is an arc-shaped structure that protrudes outward and is concentric with the main rotor.

[0027] The power output shaft of the first driving component is provided with an arc-shaped groove that matches the shape of the arc-shaped structure;

[0028] When the main turntable drives the sub-turntable to rotate to the detection position, the arc-shaped structure is confined within the arc-shaped groove, and the first driving member drives the sub-turntable and the corresponding drill core to rotate.

[0029] In conjunction with the first aspect, in one possible implementation, the wall of the collection tank is provided with an illumination strip, the illumination strip extends vertically, and the illumination side of the illumination strip is inclined toward the container hole.

[0032] For example, the support frame is provided with a slide rail adapted to extend along the interval direction between the first collector and the core sample storage device, and the first collector is slidably connected to the slide rail.

[0033] The solution shown in this application embodiment allows the information acquisition end, acquisition slot, and container hole of the first collector to be sequentially aligned, so that the first collector can acquire the surface information of the drill core in the corresponding container hole through the acquisition slot. The first collector is electrically connected to the controller so that the controller can receive the above surface information, thereby facilitating the inspection personnel to judge the quality of the drill core based on the above surface information, and thus determine the quality of the corresponding pile body. Furthermore, the first driving component can drive the drill core to rotate, so that the outer peripheral wall of the drill core can be rotated sequentially to the exposed area of ​​the acquisition slot, facilitating the first collector to fully acquire the surface information of the drill core.

[0034] Compared with existing technologies, the pile foundation core drilling and testing system provided in this application can acquire surface information without transferring the core after it is placed in the core sample storage container. This avoids problems such as core damage and misnumbering during transfer, effectively ensuring the authenticity and accuracy of the core drilling and testing. It is also simple and labor-saving to operate, which can effectively improve the efficiency of testing. Furthermore, the collected surface information can be stored through the controller, ensuring the traceability of the core drilling and testing process and facilitating subsequent verification.

[0049] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0050] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0051] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0052] Please refer to the following: Figures 1 to 6 The pile foundation core drilling detection system and detection method provided by the present invention will now be described. The pile foundation core drilling and testing system includes a core sample storage unit 1, a rotating assembly 2, and a testing assembly. The core sample storage unit 1 has a holding hole 1221 for placing the drill core 9, which extends vertically. The core sample storage unit 1 also has a collection groove extending vertically, which communicates with the holding hole 1221. The rotating assembly 2 includes a sub-rotor 21 located at the bottom of the holding hole 1221 and a first drive member 22 located below the sub-rotor 21. The top of the sub-rotor 21 supports the drill core 9. The bottom of the sub-rotor 21 extends downward to be poweredly connected to the first drive member 22. The testing assembly includes a first collector 3 located on one side of the collection groove and a controller electrically connected to the first collector 3. In the radial direction of the core sample storage unit 1, the holding hole 1221, the collection groove, and the information collection end of the first collector 3 corresponding to the drill core 9 are sequentially aligned. The first collector 3 is used to collect surface information of the drill core 9 through the collection groove, and the controller can receive the surface information collected by the first collector 3.

[0053] It should be noted that the first collector 3 used in this application can be set inside the core sample storage 1, so that the first collector 3 collects the surface information of the drill core 9 in the corresponding holding hole 1221 through the collection groove; or, the first collector 3 can be set outside the core sample storage 1, so that the first collector 3 collects the surface information of the drill core 9 in the corresponding holding hole 1221 through the collection groove; optionally, the first collector 3 and the second collector 7 can be set outside and inside the core sample storage 1 respectively, so as to collect information twice on the same area of ​​the drill core 9, and the accuracy of the collected information can be improved by comparing them with each other.

[0054] In addition, the controller used in this application is an integrated structure composed of multiple control elements through programming. The controller is equipped with a storage element for storing the above-mentioned surface information and a processing element for information processing. Furthermore, the detection component also includes components such as a display, which is used to facilitate the operator to view and determine the quality of the drill core 9. It should be noted that the structure, working principle, and connection method of this part of the controller and display are all prior art and will not be described in detail here.

[0055] For example, when each core sample storage unit 1 is provided with only one set of holding holes 1221, multiple core sample storage units 1 need to be used to hold multiple sets of drill cores 9 in sequence. During testing, the core sample storage units 1 need to be switched in sequence and the sampling slots of each core sample storage unit 1 need to be aligned with the sampling end of the first collector 3.

[0056] For example, when each core sample storage unit 1 is provided with multiple sets of holding holes 1221, multiple sets of drill cores need to be sequentially placed into the core sample storage unit 1. At this time, the core sample storage unit 1 is provided with multiple holding holes 1221, and each holding hole 1221 corresponds to a collection slot. During testing, the core sample storage unit 1 needs to be rotated so that the holding hole 1221, collection slot and information collection end of the first collector 3 corresponding to the drill core 9 to be tested are sequentially aligned, so as to facilitate the first collector 3 to collect surface information.

[0057] Specifically, the core sample storage unit 1 can be rotated manually so that the corresponding holding hole 1221, the collection slot and the information collection end of the first collector 3 of the drill core 9 to be tested are aligned in sequence; or the core sample storage unit 1 can be rotated by a third driving component; specifically, the third driving component can be selected as a rotating motor.

[0058] Optionally, the first information collector and the second information collector mentioned later can be a camera, scanner, or other device capable of recording surface information of the drill core 9. It should be noted that the specific working principles and connection methods of the first and second information collectors are existing technologies and will not be elaborated here. It should be understood that the shapes of the first collector 3 and the second collector 7 described in the accompanying drawings are only for illustrative purposes and do not represent the specific structures of the first collector 3 and the second collector 7.

[0059] It should be understood that the first collector 3 of the detection component collects surface information of the drill core 9 through the collection slot corresponding to the holding hole 1221. The collection position is precisely matched, so that the collected surface information more accurately reflects the actual situation of the drill core 9, thereby improving the accuracy and reliability of pile foundation quality detection.

[0060] The pile foundation core drilling inspection system provided by this invention, compared with the prior art, allows the information acquisition end and acquisition slot of the first acquisition device 3 to be sequentially aligned with the container hole 1221. This enables the first acquisition device 3 to acquire surface information of the drill core 9 within the corresponding container hole 1221 through the acquisition slot. The first acquisition device 3 is electrically connected to the controller, allowing the controller to receive the aforementioned surface information. This facilitates the inspection personnel in judging the quality of the drill core 9 based on the surface information, thereby determining the quality of the corresponding pile body. Furthermore, the first driving member 22, by driving the drill core 9 to rotate, can make the outer peripheral wall of the drill core 9... The core samples are rotated sequentially to the exposed area of ​​the sampling slot, facilitating the first sampler 3 to comprehensively collect the surface information of the core sample 9. The pile foundation core sampling system provided in this application can acquire the surface information of the core sample 9 without transferring it after it is placed in the core sample storage 1. This avoids the problems of core sample 9 damage and numbering errors during the transfer process, effectively ensuring the authenticity and accuracy of the core sample 9 detection. It is also simple to operate, labor-saving, and can effectively improve the efficiency of the detection. Furthermore, the collected surface information can be stored through the controller, ensuring the traceability of the core sample 9 detection process and facilitating subsequent verification.

[0061] Please see Figure 1 and Figure 2 In some possible embodiments, the core sample storage device 1 includes a core sample box 11 and a main rotating module 12; the core sample box 11 has a first collection groove 111 extending radially through its wall; the main rotating module 12 is disposed inside the core sample box 11; a plurality of holding holes 1221 are spaced apart circumferentially inside the main rotating module 12; the main rotating module 12 has a detection position; the main rotating module 12 has a plurality of second collection grooves 1222 corresponding to and communicating with the holding holes 1221, and each second collection groove 1222 is... The process extends to the outer peripheral wall of the main rotating module 12; wherein, a sub-rotating disk 21 is correspondingly provided in each holding hole 1221, and the power output end of the first driving member 22 is connected to the extension end of the sub-rotating disk 21 that has rotated to the detection position, so as to drive the sub-rotating disk 21 and the corresponding drill core 9 to rotate; the collection slot includes a second collection slot 1222 and a first collection slot 111. In the radial direction of the core sample storage 1, the second collection slot 1222 and the first collection slot 111 that have rotated to the detection position correspond to the collection end position of the first collector 3.

[0062] In this application, the rotation of the main rotating module 12 causes multiple holding holes 1221 to rotate sequentially to the detection position, which allows for continuous detection of multiple drill cores 9, improving detection efficiency and enabling flexible selection of different drill cores 9 for focused or comprehensive detection.

[0063] Each holding hole 1221 is provided with a corresponding sub-rotary disk 21. Therefore, the drill core 9 in each holding hole 1221 is correspondingly set on the sub-rotary disk 21. When the holding hole 1221 rotates to the detection position, the sub-rotary disk 21 drives the corresponding drill core 9 to rotate, so that the outer peripheral wall area of ​​the drill core 9 is exposed to the collection slot in sequence, thereby facilitating the first collector 3 to fully collect its surface information, ensuring the comprehensiveness of the collected surface information of the drill core 9, and ensuring the accuracy of the detection results.

[0064] Optionally, multiple windows 112 are provided on the core sample box 11, and except for the detection position, each window 112 corresponds to a collection slot of a holding hole 1221, and each window 112 is provided with transparent glass to facilitate observation of the internal drill core 9.

[0065] The core sample storage unit 1 also includes a lower box 13, which is supported at the bottom of the main rotating module 12 and is fixedly connected to the core sample box 11. The lower box 13 is provided with a second driving member 131, which is poweredly connected to the main rotating module 12 to drive the main rotating module 12 to rotate, thereby causing the multiple holding holes 1221 to rotate sequentially to the detection position. The lower box 13 also contains a first driving member 22.

[0066] The lower box 13 supports the bottom of the main rotating module 12 and is fixedly connected to the core sample box 11. The first driving component 22 is contained inside. This structural layout makes the whole system compact, reduces the space occupied, and facilitates the connection between the components and the power transmission, thereby improving the stability and reliability of the system.

[0067] Please see Figure 3 In some embodiments, the main rotating module 12 includes a main turntable 121 and a mounting mold 122; the main turntable 121 is located at the bottom of the core sample box 11 and is poweredly connected to the second driving member 131; the mounting mold 122 is connected to the top of the main turntable 121; the mounting mold 122 is provided with a holding hole 1221 and a second collection groove 1222; wherein, each sub-turntable 21 is limited on the main turntable 121, and the upper end of the sub-turntable 21 extends upward into the holding hole 1221, and the lower end extends downward through the main turntable 121.

[0068] The main turntable 121 is poweredly connected to the second drive unit 131, and each sub-turntable 21 is limited on the main turntable 121, so that the second drive unit 131 can efficiently drive each sub-turntable 21 to rotate through the main turntable 121, thereby realizing the sequential rotation of the holding hole 1221 and driving the corresponding drill core 9 to rotate to the detection position in sequence, ensuring the smoothness and efficiency of the detection process.

[0069] In addition, the upper end of the sub-rotor 21 extends upward into the holding hole 1221, and the lower end extends downward through the main rotor 121. This arrangement ensures that the sub-rotor 21 can stably support the drill core 9, and also provides good limiting for the sub-rotor 21 during rotation, preventing it from shaking or shifting, ensuring the stability of the drill core 9 during rotation, and thus ensuring the accuracy of the collected information.

[0070] Please see Figure 3 and Figure 4 For example, the mounting mold 122 has a ring structure, and the main turntable 121 is provided with an annular limiting hole 1211 adapted to the annular structure. The bottom of the mounting mold 122 is limited within the annular limiting hole 1211. The bottom of the annular limiting hole 1211 is provided with multiple downwardly penetrating limiting step holes 1212 at intervals. Multiple filling holes 1221 and multiple limiting step holes 1212 correspond one-to-one. The sub-turntable 21 is limited within the corresponding limiting step hole 1212.

[0071] The mounting mold 122 has a ring structure, with its bottom limited within the ring-shaped limiting hole 1211 of the main turntable 121. The sub-turntable 21 is limited within the corresponding limiting step hole 1212. This precise installation and positioning method ensures the positional accuracy of each sub-turntable 21 and its corresponding holding hole 1221, making the structure of the entire detection system more stable and the cooperation between the components more precise, thereby improving the accuracy and reliability of the detection.

[0072] In addition, the sub-rotor 21 is limited by the limiting step hole 1212, which effectively prevents the sub-rotor 21 from being misaligned or shifted during rotation, ensuring the normal operation of the rotating assembly 2 and guaranteeing the stability of the drill core 9 and the accuracy of the collected information during the detection process.

[0073] Please see Figure 2 and Figure 3 For example, the inner annular side of the mounting mold 122 is provided with a plurality of third collection slots 1223 that correspond one-to-one with the holding holes 1221 and are connected to each other. The third collection slots 1223 extend in the vertical direction. The inner annular side of the main rotating module is provided with a second collector 7. The second collector 7 is electrically connected to the controller. In the radial direction of the mounting mold 122, the collection end of the second collector 7, the third collection slots 1223 and the holding holes 1221 correspond to each other in sequence.

[0074] Multiple third collection slots 1223, corresponding one-to-one with the holding holes 1221, are provided on the inner annular side of the mounting mold 122. Simultaneously, a second collector 7 is provided within the annular area of ​​the main rotating module 12, facilitating the collection of surface information of the drill core 9 within the corresponding holding hole 1221 via the third collection slots 1223. In the radial direction of the mounting mold 122, the collection end of the second collector 7, the third collection slots 1223, and the holding holes 1221 correspond sequentially, ensuring that the collection end of the second collector 7 can accurately collect the surface information of the drill core 9.

[0075] It should be understood that in this application, the first collector 3 can collect the first surface information of the drill core 9, and the second collector 7 can collect the second surface information of the corresponding drill core 9. On the one hand, information can be collected from the drill core 9 from different angles and directions, increasing the collection dimension and enabling the acquisition of more comprehensive information about the drill core 9, which helps to more accurately assess the quality of the pile foundation. On the other hand, the first and second collected information can be compared with each other, so that if one set of surface information is unclear or ambiguous, its actual situation can be determined by its control group information.

[0076] Optionally, when the length of the drill core 9 is large, the acquisition ends of the first acquisition device 3 and the second acquisition device 7 can be staggered vertically to acquire surface information of the drill core 9 at different heights, thereby forming multi-angle surface information. This allows the acquisition results to more comprehensively reflect the condition of the drill core 9, providing richer data support for judging the quality status of the pile foundation at different depths, and thus more comprehensively and accurately assessing the overall quality of the pile foundation.

[0077] Please see Figure 5 In some embodiments, the bottom of the sub-rotor 21 is provided with a connecting boss 211, which is an outwardly protruding arc-shaped structure concentric with the main rotor 121; the power output shaft of the first drive member 22 is provided with an arc-shaped groove 221 that matches the shape of the arc-shaped structure; wherein, when the main rotor 121 drives the sub-rotor 21 to rotate to the detection position, the arc-shaped structure is limited in the arc-shaped groove 221, and the first drive member 22 drives the sub-rotor 21 and the corresponding drill core 9 to rotate.

[0078] When the main turntable 121 drives the sub-turntable 21 to rotate to the detection position, the arc-shaped structure is limited within the arc-shaped groove 221. This unique structural design realizes a reliable power connection between the first driving component 22 and the sub-turntable 21, ensuring that the sub-turntable 21 can rotate stably and guaranteeing the normal progress of the core drilling 9 detection process.

[0079] In addition, the cooperation between the arc-shaped structure and the arc-shaped groove 221 can effectively prevent the connection from loosening or disengaging during rotation, thereby improving the stability and reliability of the system and ensuring the accuracy of the test results. On the other hand, since the main turntable 121 rotates in a circular motion, by making the arc-shaped structure concentric with the main turntable 121, it is convenient for the arc-shaped structure to rotate into the corresponding arc-shaped groove 221.

[0080] Please see Figure 6 In some possible embodiments, an illumination strip 5 is provided on the wall of the collection tank, the illumination strip 5 extends in a vertical direction, and the illumination side of the illumination strip 5 is inclined toward the container hole 1221.

[0081] The wall of the acquisition tank is equipped with a vertically extending lighting strip 5, which can provide sufficient light for collecting information from the surface of the drill core 9. This ensures that the first collector 3 and the second collector 7 can clearly obtain the features of the surface of the drill core 9 when collecting information, avoiding incomplete or inaccurate information due to insufficient light, and improving the accuracy of detection.

[0082] It is important to understand that adequate lighting can make the details on the surface of the core 9 more clearly visible, making it easier for the data collector to accurately collect the required surface information, such as defects like cracks and holes, thus providing a more reliable basis for assessing the quality of the pile foundation.

[0083] In addition, the lighting strip 5 can be installed individually or simultaneously on the first collection slot 111, the second collection slot 1222 or the third collection slot 1223, and the specific installation position can be selected according to actual needs.

[0084] Please see Figure 6 In some embodiments, the lighting strip 5 is provided in two sets, and the two sets of lighting strip 5 are respectively provided on the opposite sides of the collection tank wall.

[0085] The two sets of lighting strips 5 can illuminate the drill core 9 from both sides, enhancing the lighting effect and ensuring that all parts of the drill core 9 surface are fully illuminated, further improving the clarity and accuracy of the collected information.

[0086] Meanwhile, the tilted lighting on both sides can effectively reduce the shadows on the surface of the core 9, avoid deviations in the information collected by the data acquisition device due to shadows, ensure that the collected information on the surface of the core 9 is true and reliable, and help to more accurately assess the quality of the pile foundation.

[0087] Please see Figure 2 For example, the pile foundation core drilling detection system also includes a support frame 4, a core sample storage unit 1 and a first collector 3 are spaced apart on the support frame 4, and a telescopic drive unit 6 is provided between the first collector 3 and the support frame 4. The telescopic drive unit 6 is used to push the first collector 3 closer to or away from the collection slot.

[0088] By using the telescopic drive 6 to push the first collector 3 closer to or further away from the collection slot, the distance between the first collector 3 and the drill core 9 can be flexibly adjusted to adapt to drill cores 9 of different specifications or conditions, ensuring that the collector can collect clear and accurate surface information at the optimal distance, thus improving the adaptability and accuracy of the detection.

[0089] Optionally, the telescopic drive 6 is one or more of a telescopic cylinder, a telescopic hydraulic cylinder, or an electric push rod.

[0090] Please see Figure 1 For example, the support frame 4 is provided with a slide rail 41 adapted to extend along the interval direction between the first collector 3 and the core sample storage 1, and the first collector 3 is slidably connected to the slide rail 41.

[0091] The first collector 3 is slidably connected to the slide rail 41 on the support frame 4, which enables the first collector 3 to maintain a stable movement trajectory when it approaches or moves away from the collection slot, ensuring the stability of the collection process, reducing the problem of inaccurate collection information caused by collector shaking or offset, and improving the reliability of detection.

[0092] Optionally, a guide rod is also provided between the support frame 4 and the first collector 3. The guide rod passes through the support frame 4 so that the guide rod and the slide rail 41 cooperate vertically to guide the movement of the first collector 3.

[0093] This application provides a method for core drilling testing of pile foundations, which uses the aforementioned pile foundation core drilling testing system and includes the following steps:

[0094] First, start the first collector 3; second, align the collection slot corresponding to the set of drill cores 9 to be tested with the collection end of the first collector 3; then, drive the first drive component 22 to rotate the corresponding drill core 9 so that the first collector 3 can collect the first surface information of the drill core 9 in the corresponding holding hole 1221 through the collection slot, and the controller can receive the first surface information; until multiple sets of drill cores 9 are tested in sequence.

[0095] For example, when each core sample storage unit 1 is provided with only one set of holding holes 1221, and it is necessary to switch to another set of drill cores 9 for testing, a new core sample storage unit 1 needs to be replaced to test another set of drill cores 9, until multiple core sample storage units 1 are replaced and multiple sets of drill cores 9 are tested; and after switching core sample storage units 1, the sampling slots of each core sample storage unit 1 need to be aligned with the sampling end of the first collector 3.

[0096] For example, when each core sample storage unit 1 is provided with only multiple sets of holding holes 1221, each holding hole 1221 corresponds to a collection slot. The core sample storage unit 1 can be manually rotated by the third driving component so that the multiple collection slots are aligned with the collection end of the first collector 3 in sequence, thereby facilitating the first collector 3 to collect surface information.

[0097] For example, when the above-mentioned pile foundation core drilling detection system is used, and the sampling slots include a first sampling slot 111, a second sampling slot 1222, and a third sampling slot 1223, firstly, multiple sets of drill cores 9 to be tested are sequentially installed into the mounting mold 122 of the core sample storage component 1; the first collector 3 and the second collector 7 are started; secondly, the second drive component 131 is driven, causing the second drive component 131 to drive the main turntable 121 to rotate, so that the drill cores 9 and the main rotation module 12 rotate with the main turntable 121, and the set of drill cores 9 to be tested is moved to the detection position; then, the first drive component 22 is driven, causing the first drive component 22 to drive the main rotation module 122 to rotate. 2 drives the sub-rotor 21 and the corresponding drill core 9 to rotate, so that the first collector 3 can collect the first surface information of the drill core 9 in the corresponding holding hole 1221 through the first collection groove 111 and the second collection groove 1222, and the second collector 7 can collect the second surface information of the drill core 9 in the corresponding holding hole 1221 through the third collection groove 1223. The controller can receive the first surface information and the second surface information so that the operator can judge the quality of the drill core 9 based on the first surface information and the second surface information, and then obtain the quality of the pile body corresponding to the drill core 9; until multiple sets of drill cores 9 are tested in sequence.

[0098] It should be noted that the above-mentioned pile foundation core drilling test method also includes detecting the length of the core 9 to determine whether the core 9 has a breakage problem. Specifically, before placing the core 9 into the core sample storage container 1, the actual length of the core 9 needs to be measured, and the difference between the theoretical drilling length and the actual length of the pile body drilling is used to determine the integrity of the core 9. When the difference is 0 or within the preset error range, the integrity of the core 9 is determined. When the difference exceeds the preset error range, it indicates that there may be a breakage or damage to the core 9 during the core drilling process, and it needs to be drilled again.

[0099] The pile foundation core drilling test method provided in this application has all the beneficial effects of the above-mentioned pile foundation core drilling test system because it adopts the above-mentioned pile foundation core drilling test system. It can avoid the problems of damage and numbering confusion of the core 9 during the transfer process, and effectively ensure the authenticity and accuracy of the core 9 test.

[0100] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
