Description

Technical Field

[0001] The invention relates to the technical field of vibro-hole making, and in particular to an intelligent safety control method, device and medium for vibro-hole making. Background Art

[0002] The vibro-impact construction process consists of three steps: hole guiding, hole making, and pile making. During the hole making process, a hole making method based on intelligent control vibro-impact is proposed, with application publication number CN115653486A. In the hole making method, a reverse insertion thread is proposed. The reverse insertion thread will control the vibrator to stop descending and synchronize the timing only when the tension F is less than the minimum tension Fmin for hole making (because the vibrator is blocked by the lower stone). When t≥tmax, the vibrator is controlled to be lifted up and reversed.

[0003] However, the above-mentioned hole-making method does not consider the following situation: when the tension F is less than the minimum tension Fmin for hole-making, the vibrator stops descending by controlling the winch to stop. At this time, controlling the vibrator to stop descending does not mean that the vibrator will not still be vibrating, and the vibration of the vibrator is very likely to hollow out the lower layer of stone. Therefore, when the tension F is less than the minimum tension Fmin for hole-making, the tension F will jump due to the hollowing out of the lower layer of stone. When the tension F jumps greatly, it means that the reverse insertion program does not need to be started, and the winch can continue to descend. Therefore, based on the above considerations, the present invention proposes an intelligent safety control method for vibratory hole-making. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent safety control method, device and medium for vibro-punching. The intelligent safety control method mainly continuously monitors the jump of tension F during the process of tension F≤min minimum tension Fmin for hole making, and chooses to start or stop the reverse insertion thread or restore the reverse insertion thread during the process of monitoring the jump of tension F, so as to realize intelligent safety control of vibro-punching.

[0005] In order to solve the above technical problems, the present invention adopts the following solutions:

[0006] An intelligent safety control method for vibro-hole making includes an acoustic wave sensor located in the hole making, and the method specifically includes the following steps:

[0007] S1, hole-making speed detection: detect whether the hole-making speed is continuously less than the minimum speed within the minimum preset time or less than the maximum speed within the maximum preset time. If not, go to step S2;

[0008] S2, hole-making state matching: matching the current hole-making state. If the current hole-making state is the hole-making descending state, go to step S3; if the current hole-making state is the hole-making stopping state, go to step S4;

[0009] S3, hole-making descending state control: match the current tension, if the current tension F≤ the minimum hole-making tension Fmin, change the current hole-making state to the hole-making stop state, and re-match according to the changed current hole-making state, that is, go to step S2, at the same time, control the winch to stop, and start timing the hole-making stop time;

[0010] S4, hole-making stop state control: match the current tension, if the current tension F is less than the maximum hole-making tension Fmax, check whether the current hole-making stop time is greater than or equal to the stage maximum time and less than the hole-making resistance allowable lifting time, if so, go to step S5;

[0011] S5. Hole-making interruption control based on winch lifting and reverse insertion: control the winch lifting and reverse insertion, and simultaneously analyze whether the sound waves detected by the sound wave sensor during the time period of the winch lifting and reverse insertion meet the sound wave characteristics of stone impact, and determine whether the cumulative number of times the sound waves continuously meet the sound wave characteristics of stone impact is greater than a threshold. If so, control the winch to stop, the hole-making is abnormal, and prompts for manual intervention.

[0012] Furthermore, the S5 specifically includes the following steps:

[0013] S51: Control the winch to lift up to a temporary lifting depth, then reverse the insertion, and start the sonic sensor at the same time;

[0014] S52: Obtain all the sound waves generated during the period of lifting and reverse insertion of the winch through the sound wave sensor, and analyze the sound waves in turn to see whether they meet the sound wave characteristics of stone impact. If so, add one to the counter, if not, reset the counter to zero;

[0015] S53: When all the sound wave analyses are completed, the current value of the counter is read to determine whether the current value is greater than the threshold value. If so, the winch is controlled to stop, the hole making is abnormal and a manual intervention is prompted; if not, the current hole making state is changed to the hole making descending state, and the winch is controlled to descend.

[0016] Furthermore, the acoustic wave sensor is a hydrophone arranged in the hole or a Rayleigh wave sensor arranged on the vibrator.

[0017] Furthermore, in S1, it is detected whether the drilling speed is continuously less than the minimum speed within the minimum preset time or less than the maximum speed within the maximum preset time. If so, it is necessary to perform drilling depth detection to detect whether the current drilling depth is greater than or equal to the geological survey reference value of the third layer. If so, the winch is controlled to stop and the drilling is completed; if not, the winch is controlled to stop, the drilling is abnormal and manual intervention is prompted.

[0018] Furthermore, S3 specifically includes the following steps:

[0019] S31: Match the current tension. If the current tension F≤ the minimum tension Fmin for hole making, go to step S32; if the current tension F>the minimum tension Fmin for hole making, go to step S33;

[0020] S32: changing the current hole-making state to the hole-making stop state, and rematching according to the changed current hole-making state, that is, going to step S2, and at the same time, controlling the winch to stop and starting to count the hole-making stop time;

[0021] S33: Control the winch to descend.

[0022] Furthermore, the S4 specifically includes the following steps:

[0023] S41: Match the current tension. If the current tension F is less than the maximum tension Fmax for hole making, go to step S42; if the current tension F is greater than or equal to the maximum tension Fmax for hole making, go to step S43;

[0024] S42: Check whether the current hole-making stop time is greater than or equal to the stage maximum time and less than the hole-making resistance allowable lifting time. If so, go to step S5; if not, control the winch to stop;

[0025] S43: Change the current hole-making state to the hole-making descending state, and control the winch to descend.

[0026] Furthermore, the third layer is a stratigraphic number, and the third layer refers to the alluvial deposit containing drifted sand and gravel layer alQ3 3-2 .

[0028] a memory for non-transitory storage of computer readable instructions;

[0029] The processor is used to execute the computer-readable instructions, and the computer-readable instructions, when executed by the processor, implement the intelligent safety control method for vibro-fracturing.

[0030] A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores computer-readable instructions, and when the computer-readable instructions are executed by a processor, the intelligent safety control method for vibro-fracturing is implemented.

[0031] Beneficial effects of the present invention:

[0032] The present invention provides an intelligent safety control method, device and medium for vibro-punching. The intelligent safety control method mainly continuously monitors the jump of tension F in the process of tension F≤ minimum tension Fmin for hole making. In the process of monitoring the jump of tension F, the method selects to start and restore the reverse insertion thread or start and stop the reverse insertion thread through timing, so as to realize intelligent safety control of vibro-punching.

[0033] In addition, an interrupt protection operation is added for recovering the reverse insertion thread, so that an acoustic sensor is used for monitoring during the reverse insertion process. The accumulated number of times the acoustic wave detected by the acoustic sensor during the time period of the winch lifting and reverse insertion meets the acoustic wave characteristics of stone impact is monitored, and whether the current hole making is abnormal is determined by the accumulated number of times, thereby improving the safety of vibration-impact hole making.

If so, the winch is controlled to stop, the hole making is abnormal and a manual intervention is prompted; if not, the current hole making state is changed to the hole making descending state, and the winch is controlled to descend.

[0057] Preferably, the acoustic wave sensor is a hydrophone arranged in the pore or a Rayleigh wave sensor arranged on the vibrator.

[0058] Preferably, in S1, it is detected whether the drilling speed is continuously less than the minimum speed within the minimum preset time or less than the maximum speed within the maximum preset time. If so, it is necessary to perform drilling depth detection to detect whether the current drilling depth is greater than or equal to the geological survey reference value of the third layer.

[0067] Preferably, the third layer is a stratigraphic number, and the third layer refers to an alluvial deposit containing drifted sand and gravel layer alQ3 3-2 .

[0068] Based on the above principles, the present invention is further described:

[0069] Currently, if Figure 1 As shown, in the process of hole making, the winch is usually controlled to descend first. During the process of the winch descending, the tension is detected. When the tension F is less than the minimum tension Fmin for hole making, the vibrator is stopped from descending, that is, the winch is controlled to stop lowering the vibrator; when the tension F is greater than or equal to the maximum tension Fmax for hole making, the vibrator is kept descending, that is, the winch is controlled to descend. Among them, when the tension F is less than the minimum tension Fmin for hole making, it means that the current hole making is blocked, that is, the current vibrator is resisted by the lower stone when it descends, and further judgment is required. In this case, the winch is usually controlled to stop lowering the vibrator, and the timing is started synchronously. When the timing t is greater than or equal to tmax, the vibrator is controlled to be lifted and reversed, that is, it rises to a specified height and then descends again.

[0070] It can be seen that in the prior art, the tension F needs to be continuously maintained less than the minimum tension Fmin for hole making in order to control the vibrator to lift and reversely insert, and the phenomenon of jump in the tension F is not considered. This jump phenomenon is due to the fact that when the tension F is less than the minimum tension Fmin for hole making, the vibrator stops descending by controlling the winch to stop. At this time, controlling the vibrator to stop descending does not mean that the vibrator will not still be in vibration, and the vibration of the vibrator is very likely to hollow out the lower layer of stone. When the tension F is less than the minimum tension Fmin for hole making, the tension F will jump due to the hollowing out of the lower layer of stone. When the tension F jumps greatly, it means that the reverse insertion program does not need to be started and the winch can continue to descend.

[0071] Therefore, based on the above considerations, the present invention proposes an intelligent safety control method for vibro-punching. The intelligent safety control method mainly monitors the jump of the tension F continuously during the process of tension F ≤ minimum tension Fmin for hole making. During the monitoring process, if a jump in the tension F is found, the recovery reverse insertion thread is started; if no jump in the tension F is found, the stop reverse insertion thread is started, thereby realizing intelligent safety control of vibro-punching.

[0072] Specifically, Figure 2 As shown, after entering the hole-making process, first, the speed needs to be recorded and the hole-making speed needs to be detected to check whether the hole-making speed is continuously less than the minimum speed within the minimum preset time or less than the maximum speed within the maximum preset time. If not, the current hole-making state is matched. The minimum preset time can be 12 minutes, the minimum speed can be 0.1 m / min, the maximum preset time can be 25 minutes, and the maximum speed can be 0.3 m / min.

[0073] The hole-making status is mainly divided into a hole-making descending state and a hole-making stop state. The hole-making descending state indicates that the current winch is descending, and the hole-making stop state indicates that the current winch has stopped descending.

[0074] When the hole-making state is the hole-making descending state, the current tension F can be matched. If the current tension F> the minimum hole-making tension Fmin, it means that there is no resistance in the current winch descent process, and the winch descent state can be maintained; if the current tension F≤ the minimum hole-making tension Fmin, it means that the current winch encounters resistance in the descent process, that is, the current vibrator is descent and encounters resistance from the lower layer of stone. At this time, the current hole-making state is changed to the hole-making stop state, that is, the winch is controlled to stop, and the hole-making stop time starts in time.

[0075] In the process of current tension F≤ minimum hole-making tension Fmin, the current hole-making state is changed to hole-making stop state, so that the current hole-making state is re-matched. At the same time, the current tension is matched in the current hole-making state. If the current tension F<maximum hole-making tension Fmax, it is detected whether the current hole-making stop time is greater than or equal to the stage maximum time and less than the allowable lifting time when the hole-making encounters resistance. If so, the recovery reverse insertion thread will be started, if not, the stop reverse insertion thread will be started.

[0076] In this embodiment, the resuming reverse insertion thread and stopping the reverse insertion thread respectively refer to resuming or stopping the original reverse insertion thread. The original reverse insertion thread refers to when the tension F is less than the minimum tension Fmin for hole making, the winch is controlled to stop lowering the vibrator, and the timing is started synchronously. When the timing t≥tmax, the vibrator is controlled to lift up and reversely insert. It can be seen that the interval section corresponding to the original reverse insertion thread is the section where the tension F is less than the minimum tension Fmin for hole making. Since, in the process where the tension F is less than the minimum tension Fmin for hole making, the tension F will jump due to the hollowing out of the lower stone, in order to continuously monitor the jump phenomenon of the tension F, the present invention chooses to use an increasing area By using the technical means of the intermediate paragraph, the paragraph where the tension F is less than the minimum tension Fmin for hole making is expanded to the paragraph where the tension F is less than the maximum tension Fmax for hole making, and the original reverse insertion thread corresponds to the paragraph where the tension F is less than the maximum tension Fmax for hole making. In the process where the current tension F is less than the maximum tension Fmax for hole making, the tension F produces a jump phenomenon, and then by detecting whether the current hole making stop time is greater than or equal to the stage maximum time and less than the allowable lifting time for hole making when encountering resistance, it is selected to start the recovery reverse insertion thread or stop the reverse insertion thread, which is equivalent to recovering or stopping the original reverse insertion thread in the paragraph where the tension F is less than the minimum tension Fmin for hole making, thereby realizing intelligent and safe control of vibro-impact hole making.

[0077] In addition, the recovery and reverse insertion thread refers to controlling the winch to lift a temporary lifting depth, which can be 0.1m, and then reverse inserting; a new interrupt protection operation is added for the recovery and reverse insertion thread. The interrupt protection operation mainly triggers the stop of hole making by detecting the continuous number of sound waves that meet the characteristics of stone impact, thereby playing a protective role in the process of lifting and reverse inserting of the winch.

[0078] Specifically, it is mainly based on a pre-set acoustic wave sensor, which uses a hydrophone or a Rayleigh wave sensor, such as Figure 3 As shown, the hydrophone is arranged in the hole, as shown in FIG. Figure 4 As shown, the Rayleigh wave sensor is arranged on the vibrator to monitor the sound waves generated during the period of lifting and reverse insertion of the winch.

[0079] When the reverse insertion thread is restored, that is, when the winch is controlled to lift and reverse, the acoustic sensor is started synchronously, and the hydrophone is started for acoustic wave monitoring. Figure 3 It can be used to indicate that when the winch is lifted during the process of starting the hydrophone for acoustic wave monitoring, the vibrator still encounters resistance during the reverse insertion process after the winch is lifted, that is, it is blocked by the lower layer of stones, such as Figure 5 As shown, in Figure 5 It can be used to express Figure 3During the reverse insertion process of the winch, the vibrator is blocked by the lower layer of stones, that is, the vibrator collides with the lower layer of stones, and sound waves are generated during the collision. Therefore, the present invention obtains all sound waves generated during the time period of the winch reverse insertion monitored by the sound wave sensor, and analyzes in turn whether the sound waves meet the sound wave characteristics of stone collision. If so, the counter count is increased by one, if not, the counter count is reset to zero; when all sound wave analyses are completed, the current value of the counter is read to determine whether the current value is greater than the threshold value. If so, the winch is controlled to stop, the hole making is abnormal and manual intervention is prompted; if not, the current hole making state is changed to the hole making descending state, and the winch is controlled to descend.
