[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 quantity of the technical features being referred to. Thus, a feature identified as "first," "second," or "third" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0052] Please also refer to Figures 1 to 6 , the pile foundation core drilling detection system and detection method provided by the present invention are now described. The pile foundation core drilling detection system includes a core sample storage unit 1, a rotating assembly 2, and a detection assembly. The core sample storage unit 1 has a vertically extending receiving hole 1221 for receiving the drill core 9. The receiving hole 1221 is further provided on the core sample storage unit 1 with a vertically extending collecting trough that is connected to the receiving hole 1221. The rotating assembly 2 includes a sub-rotating disc 21 disposed at the bottom of the receiving hole 1221 and a first driving member 22 located below the sub-rotating disc 21. The drill core 9 is supported at the top of the sub-rotating disc 21. The bottom of the sub-rotating disc 21 extends downwardly for power connection to the first driving member 22. The detection assembly includes a first collector 3 disposed on one side of the collecting trough and a controller electrically connected to the first collector 3. In the radial direction of the core sample storage unit 1, the receiving hole 1221, the collecting trough, and the information collection end of the first collector 3 corresponding to the drill core 9 to be detected correspond in sequence. The first collector 3 is used to collect surface information of the drill core 9 through the collecting trough, and the controller is capable of receiving the surface information collected by the first collector 3.

[0053] It should be noted that the first collector 3 used in the present application can be arranged 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 collecting groove; or, the first collector 3 is arranged 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 collecting groove; optionally, the first collector 3 and the second collector 7 are correspondingly arranged outside and inside the core sample storage 1 to collect information twice on the same area of ​​the drill core 9, and the accuracy of the collected information can be improved by mutual comparison.

[0054] In addition, the controller used in the present application is integrated into an integrated structure by programming a plurality of control elements, and the controller is provided with a storage element for storing the above-mentioned surface information, and a processing element for realizing information processing, etc.; and the detection component also includes components such as a display, and the display is used to facilitate the operator to view in order to determine the quality of the drill core 9; it should be noted that the structure and working principle of this part of the controller and display, as well as the connection method, etc., belong to the prior art and will not be repeated here.

[0055] For example, when only one set of containing holes 1221 is provided in each core sample storage 1, multiple core sample storages 1 need to be sequentially filled with multiple sets of drill cores 9. During detection, the core sample storages 1 need to be switched sequentially, and the collection slots of each core sample storage 1 need to be aligned with the sampling end of the first collector 3.

[0056] For example, when multiple groups of containing holes 1221 are provided in each core sample storage 1, multiple groups of drill cores need to be sequentially contained in the core sample storage 1. At this time, multiple containing holes 1221 are provided in the core sample storage 1, and each containing hole 1221 corresponds to a collecting slot. During testing, the core sample storage 1 needs to be rotated so that the containing holes 1221, the collecting slots and the information collecting end of the first collector 3 corresponding to the drill core 9 to be tested correspond in sequence, thereby facilitating the first collector 3 to collect surface information.

[0057] Specifically, the core sample storage 1 can be rotated by manual operation so that the holding hole 1221, the collection slot and the information collection end of the first collector 3 corresponding to the drill core 9 to be tested correspond in sequence; or the core sample storage 1 can be driven to rotate by a third driving member; specifically, the third driving member can be optionally set to a rotating motor.

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

[0059] It should be understood that the first collector 3 of the detection component collects the surface information of the drill core 9 through the collection slot corresponding to the containing hole 1221, and the collection position corresponds precisely, 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] Compared with the prior art, the pile foundation core drilling detection system provided by the present invention can make the information collection end and the collection slot of the first collector 3 correspond to the receiving hole 1221 in sequence, so that the first collector 3 collects the surface information of the drill core 9 in the corresponding receiving hole 1221 through the collection slot, and is electrically connected to the controller through the first collector 3 so that the controller receives the above surface information, thereby facilitating the detection personnel to judge the quality of the drill core 9 according to the above surface information, and then obtain the quality of the corresponding pile body; and the first driving member 22 can make the outer peripheral wall of the drill core 9 rotate by driving the drill core 9 It rotates sequentially to the exposed area of ​​the collection slot, which facilitates the first collector 3 to comprehensively collect the surface information of the drill core 9; the pile foundation core detection system provided in the present application can obtain its surface information without transferring the drill core 9 after the drill core 9 is placed in the core sample storage 1, which can avoid the problems of damage to the drill core 9 and number confusion during the transfer process, effectively ensure the authenticity and accuracy of the drill core 9 detection, and is simple to operate, labor-saving, and can effectively improve the efficiency of the detection; and the collected surface information can be stored by the controller, which ensures the traceability of the drill core 9 detection process and is conducive to subsequent verification.

[0061] See also Figure 1 and Figure 2 In some possible embodiments, the core sample storage 1 includes a core sample box body 11 and a main rotating module 12; a first collecting slot 111 is provided on the box wall of the core sample box body 11 and extends radially therethrough; the main rotating module 12 is arranged in the core sample box body 11; a plurality of containing holes 1221 are provided in the main rotating module 12 at intervals along its circumference; the main rotating module 12 has a detection position; a plurality of second collecting slots 1222 are provided on the main rotating module 12 and are in one-to-one correspondence with the containing holes 1221, and each second collecting slot 1222 is It passes through the outer peripheral wall of the main rotating module 12; wherein, a sub-turntable 21 is correspondingly arranged in each containing hole 1221, and the power output end of the first driving member 22 is connected to the extension end of the sub-turntable 21 rotated to the detection position, so as to drive the sub-turntable 21 and the corresponding drill core 9 to rotate; the collecting groove includes a second collecting groove 1222 and a first collecting groove 111. In the radial direction of the core sample storage 1, the second collecting groove 1222 and the first collecting groove 111 rotated to the detection position correspond to the collecting end position of the first collector 3.

[0062] In the present application, the main rotating module 12 is rotated to rotate the multiple containing holes 1221 to the detection position in sequence, so that multiple drill cores 9 can be continuously detected, the detection efficiency is improved, and different drill cores 9 can be flexibly selected for key detection or comprehensive detection.

[0063] A sub-turntable 21 is correspondingly provided for each containing hole 1221. Therefore, the drill core 9 in each containing hole 1221 is correspondingly provided on the sub-turntable 21. When the containing hole 1221 rotates to the detection position, the sub-turntable 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 groove in turn, 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, a plurality of windows 112 are provided on the core sample box body 11 , and in addition to the detection position, each window 112 corresponds to a collection slot for containing a 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 1 also includes a lower box body 13, which is supported on the bottom of the main rotating module 12 and is fixedly connected to the core sample box body 11; a second driving member 131 is provided in the lower box body 13, and the second driving member 131 is connected to the main rotating module 12 by power to drive the main rotating module 12 to rotate, so that the multiple containing holes 1221 rotate to the detection position in sequence; the lower box body 13 also contains a first driving member 22.

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

[0067] See also Figure 3 In some embodiments, the main rotation module 12 includes a main turntable 121 and a mounting mold 122; the main turntable 121 is arranged at the bottom of the core sample box body 11 and is power-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 loading hole 1221 and a second collection slot 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 loading hole 1221, and the bottom end extends downward over the main turntable 121.

[0068] The main turntable 121 is connected to the second driving member 131 by power, and each sub-turntable 21 is limited on the main turntable 121, so that the second driving member 131 can efficiently drive each sub-turntable 21 to rotate through the main turntable 121, thereby realizing the sequential rotation of the holding holes 1221, and driving the corresponding drill cores 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-turntable 21 extends upward into the containing hole 1221, and the bottom end extends downward through the main turntable 121. This arrangement not only ensures that the sub-turntable 21 can stably support the drill core 9, but also enables the sub-turntable 21 to have good positioning during rotation to prevent it from shaking or shifting, thereby ensuring the stability of the drill core 9 during rotation and thereby ensuring the accuracy of the collected information.

[0070] See also Figure 3 and Figure 4 For example, the mounting mold 122 has an annular structure, and the main turntable 121 is provided with an annular limiting hole 1211 that is compatible with the annular structure, and the bottom of the mounting mold 122 is limited in the annular limiting hole 1211; the bottom of the annular limiting hole 1211 is provided with a plurality of downward-through limiting step holes 1212 at intervals, and the plurality of containing holes 1221 and the plurality of limiting step holes 1212 correspond one by one up and down, and the sub-turntable 21 is limited in the corresponding limiting step holes 1212.

[0071] The mounting mold 122 has an annular structure, with the bottom limited in the annular limiting hole 1211 of the main turntable 121, and the sub-turntable 21 limited in the corresponding limiting step hole 1212. This precise installation and positioning method ensures the position accuracy of each sub-turntable 21 and the corresponding containing hole 1221, making the structure of the entire detection system more stable and the coordination between the components more precise, thereby improving the accuracy and reliability of the detection.

[0072] In addition, the sub-turntable 21 is limited by the limiting step hole 1212, which effectively prevents the sub-turntable 21 from being dislocated or offset during rotation, ensures the normal operation of the rotating component 2, and ensures the stability of the drill core 9 during the detection process and the accuracy of the collected information.

[0073] See also Figure 2 and Figure 3 For example, a plurality of third collecting grooves 1223 are provided on the annular inner side of the mounting mold 122, which are connected to the filling holes 1221 in a one-to-one correspondence, and the third collecting grooves 1223 extend in the vertical direction; a second collector 7 is provided in the annular inner enclosed area of ​​the main rotating module; the second collector 7 is electrically connected to the controller; wherein, in the radial direction of the mounting mold 122, the collecting end of the second collector 7, the third collecting grooves 1223 and the filling holes 1221 correspond in sequence.

[0074] A plurality of third collection slots 1223 are provided on the inner annular surface of the mounting mold 122, corresponding one-to-one with the receiving holes 1221. A second collector 7 is also provided within the annular surface of the main rotating module 12, allowing the second collector 7 to collect surface information of the drill core 9 within the corresponding receiving holes 1221 through 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 receiving holes 1221 correspond sequentially, ensuring that the collection end of the second collector 7 can accurately capture surface information of the drill core 9.

[0075] It should be understood that in the present 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 on the drill core 9 can be collected from different angles and directions, which increases the collection dimension and can obtain more comprehensive information on the drill core 9, which helps to more accurately evaluate the quality of the pile foundation; on the other hand, the first collected information and the second collected information can be compared with each other, so that when one set of surface information is unclear or ambiguous, its actual situation can be determined through its control group information.

[0076] Optionally, when the length of the drill core 9 is relatively large, the collecting ends of the first collector 3 and the second collector 7 can be staggered up and down so as to collect surface information of the drill core 9 at different heights, thereby forming multi-angle surface information, so that the collection results can more comprehensively reflect the situation of the drill core 9, and provide richer data support for judging the quality status of the pile foundation at different depths, thereby more comprehensively and accurately evaluating the overall quality of the pile foundation.

[0077] See also Figure 5 In some embodiments, a connecting boss 211 is provided at the bottom of the sub-turntable 21, and the connecting boss 211 is an arc-shaped structure that protrudes outward and is concentric with the main turntable 121; an arc-shaped groove 221 that is adapted to the shape of the arc-shaped structure is provided on the power output shaft of the first driving member 22; wherein, when the main turntable 121 drives the sub-turntable 21 to rotate to the detection position, the arc-shaped structure is limited in the arc-shaped groove 221, and the first driving member 22 drives the sub-turntable 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 structure is limited in the arc groove 221. This unique structural design realizes a reliable power connection between the first driving member 22 and the sub-turntable 21, ensuring that the sub-turntable 21 can rotate stably and ensuring the normal progress of the core drilling 9 detection process.

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

[0080] See also Figure 6 In some possible embodiments, a lighting strip 5 is provided on the wall of the collection trough, the lighting strip 5 extends in a vertical direction, and the lighting side of the lighting strip 5 is inclined toward the inside of the containing hole 1221.

[0081] A lighting strip 5 extending in the vertical direction is provided on the wall of the collection groove, which can provide sufficient light for collecting surface information of the drill core 9, ensuring that the first collector 3 and the second collector 7 can clearly obtain the surface features of the drill core 9 when collecting information, avoiding the occurrence of incomplete or inaccurate collected information due to insufficient light, and improving the accuracy of detection.

[0082] It should be understood that sufficient lighting can make the details of the surface of the drill core 9 more clearly visible, making it easier for the collector to accurately collect the required surface information, such as defects such as cracks and holes, thereby providing a more reliable basis for the assessment of pile foundation quality.

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

[0084] See also Figure 6 In some embodiments, two groups of lighting strips 5 are provided, and the two groups of lighting strips 5 are correspondingly provided on the opposite side walls of the collection slot.

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

[0086] At the same time, the oblique lighting on both sides can effectively reduce the shadows on the surface of the drill core 9, avoid the deviation of the information collected by the collector due to the shadows, ensure that the collected surface information of the drill core 9 is true and reliable, and help to more accurately evaluate the quality of the pile foundation.

[0087] See also Figure 2 Exemplarily, the pile foundation core drilling detection system also includes a support frame 4, the core sample storage 1 and the first collector 3 are arranged on the support frame 4 at intervals, and a telescopic driving member 6 is provided between the first collector 3 and the support frame 4, and the telescopic driving member 6 is used to push the first collector 3 close to or away from the collection slot.

[0088] By pushing the first collector 3 closer to or away from the collection slot through the telescopic drive member 6, 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 states, ensuring that the collector can collect clear and accurate surface information at the optimal distance, thereby improving the adaptability and accuracy of detection.

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

[0090] See also Figure 1 Exemplarily, the support frame 4 is provided with a slide rail 41 suitable for extending along the spacing 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, so that the first collector 3 can maintain a stable moving trajectory when approaching or moving away from the collection slot, ensuring the stability of the collection process, reducing the problem of inaccurate collection information caused by shaking or offset of the collector, and improving the reliability of detection.

[0092] Optionally, a guide rod is further provided between the support frame 4 and the first collector 3 , and the guide rod is passed through the support frame 4 so that the guide rod and the slide rail 41 cooperate with each other up and down to guide the movement of the first collector 3 .

[0093] The present application provides a pile foundation core drilling detection method, which uses the above-mentioned pile foundation core drilling detection system and includes the following steps:

[0094] First, start the first collector 3; second, make the collection slot corresponding to the group of drill cores 9 to be detected face the collection end of the first collector 3; then, drive the first driving member 22 to make the first driving member 22 drive the corresponding drill core 9 to rotate, so that the first collector 3 collects the first surface information of the drill core 9 in the corresponding receiving hole 1221 through the collection slot, and the controller can receive the first surface information; until the multiple groups of drill cores 9 are detected in sequence.

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

[0096] Exemplarily, when only multiple groups of containing holes 1221 are provided in each core sample storage 1, each containing hole 1221 corresponds to a collecting slot, and the core sample storage 1 can be manually driven to rotate by a third driving member so that the multiple collecting slots are aligned with the collecting end of the first collector 3 in sequence, thereby facilitating the first collector 3 to collect surface information.

[0097] For example, when the pile foundation core drilling detection system is used, the collection slots include the first collection slot 111, the second collection slot 1222 and the third collection slot 1223. First, multiple groups of drill cores 9 to be detected are sequentially installed in the installation mold 122 of the core sample storage 1; the first collector 3 and the second collector 7 are started; secondly, the second driving member 131 is driven to drive the main turntable 121 to rotate, so that the drill cores 9 and the main rotating module 12 rotate with the main turntable 121, and the group of drill cores 9 to be detected is moved to the detection position; then, the first driving member 22 is driven to drive the first driving member 2 2 drives the sub-rotary disk 21 and the corresponding drill core 9 to rotate, so that the first collector 3 collects the first surface information of the drill core 9 in the corresponding receiving hole 1221 through the first collecting slot 111 and the second collecting slot 1222, and the second collector 7 collects the second surface information of the drill core 9 in the corresponding receiving hole 1221 through the third collecting slot 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 according to the first surface information and the second surface information, and further determine the quality of the pile body corresponding to the drill core 9; until the multiple groups of drill cores 9 are tested in sequence.

[0098] It should be noted that the above-mentioned pile foundation core drilling detection method also includes detecting the length of the drill core 9 to determine whether the drill core 9 has a breakage problem; specifically, before placing the drill core 9 into the core sample storage 1, it is necessary to measure the actual length of the drill core 9 and make a judgment based on the difference between the theoretical drilling length and the actual length of the pile body. When the difference is 0 or the difference is within the preset error range, the drilling integrity of the drill core 9 is determined. When the difference exceeds the preset error range, it indicates that the drill core 9 may be broken or damaged during the coring process and needs to be re-drilled.

[0099] The pile foundation core drilling detection method provided in the present application has all the beneficial effects of the above-mentioned pile foundation core drilling detection system due to the adoption of the above-mentioned pile foundation core drilling detection system. It can avoid the damage of the drill core 9 and the problem of number confusion during the transfer process, and effectively ensure the authenticity and accuracy of the drill core 9 detection.

[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 in the scope of protection of the present invention.
