Description

Technical Field

[0001] The invention relates to the technical field of soil layer drilling, and in particular to a comprehensive monitoring 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, an intelligent safety control method, device, and medium for vibro-impact hole making are proposed, with application publication number CN119288427A. In the hole making process, the special phenomenon that the lower layer of stone is hollowed out due to the vibration of the vibrator after the hole making stops is taken into account, and the variation range of the hole making tension is monitored to achieve safe control of the vibro-impact hole making.

[0003] Based on the above considerations, the present invention takes into account the following special phenomena: during the hole-making process, the vibrator vibrates the stratum, and the surrounding loose stratum becomes dense through the vibration to achieve hole-making. Since the compaction of the stratum corresponding to different hole-making depths is different, when the stratum is relatively loose, there may be some voids in the stratum. At this time, the vibrator penetrates the lower layer of stone through vibration and descends into certain voids without any restraint, which is quite dangerous. In addition, since the vibrator head is relatively large, if the vibrator is not controlled in time, the vibrator head may get stuck after completely entering the void, thereby causing accidents and posing a great safety hazard. Summary of the invention

[0004] The purpose of the present invention is to provide a comprehensive monitoring method, device and medium for vibro-punching. The comprehensive monitoring method is applied to the hole-making process. In the hole-making descending state, if the vibrator encounters a cavity, the hole-making process is provided with a first warning and a second warning through the correlation between the hole-making current, the hole-making tension and the hole-making descending depth. The present invention can not only prevent safety hazards through manual operation, but also effectively avoid the vibrating head from completely entering the cavity by controlling the winch to stop, thereby realizing intelligent and safe control of vibro-punching.

[0005] The present invention proposes an automatic control method and device in the process of soil drilling. The device automatically detects current, tension, and descent depth data, thereby observing the correlation between the three data in the time dimension, and analyzing the risk of encountering voids through correlation, thereby automatically controlling or warning the drilling equipment to continue to descend, thereby preventing the equipment from getting stuck.

[0006] In order to solve the above technical problems, the present invention adopts the following solutions:

[0007] A comprehensive monitoring method for vibro-hole making, the comprehensive monitoring method comprising the following steps:

[0008] S1, matching the current hole-making state. If the current hole-making state is a hole-making decreasing state, then in the current hole-making state, real-time detection is made on whether the hole-making current of the current vibrator decreases. If so, the hole-making current at this time point is marked as the current decreasing point, and the process goes to step S2;

[0009] S2. Detect the continuous state of the pore-forming current in real time from the current drop point. When the pore-forming current at several consecutive time points is within the minimum load interval, obtain the corresponding abnormal time period at the consecutive time points;

[0010] S3, extracting the state intervals of the hole-making tension and the hole-making descending depth of the current vibrator according to the abnormal time period, and performing change detection on the state interval according to the correlation between the hole-making tension and the hole-making descending depth and the hole-making current. If it is detected that the state interval is in an abnormal state, a first warning is issued, and the process goes to step S4;

[0011] S4. Obtain the current maximum allowable hole-making time of the current vibrator, and detect in real time from the time point of the current descent point whether the current time period reaches the current maximum allowable hole-making time. If so, change the current hole-making state to the hole-making stop state, control the winch to stop, and issue a second warning.

[0012] Furthermore, the first warning is used to prompt the operator to choose to control the winch to stop; the second warning is used to prompt the operator of the working status of the vibrator and the winch.

[0013] Furthermore, the minimum load interval refers to a range formed by extending the minimum hole-making current forward and backward by a preset value, and the minimum hole-making current is a starting current for starting the vibrator to perform retention vibration.

[0014] Furthermore, the step S3 includes the following steps:

[0015] S31, extracting the state intervals of the hole-making tension and hole-making drop depth of the current vibrator according to the abnormal time period, wherein the state interval is composed of the values ​​of the hole-making tension / hole-making drop depth of the current vibrator recorded in real time during the abnormal time period;

[0016] S32, respectively detecting the state intervals of the current pore-forming tension and pore-forming descending depth of the vibrator, and judging whether the state interval is in an abnormal state according to the correlation between the pore-forming tension / pore-forming descending depth and the pore-forming current and the value of the pore-forming tension / pore-forming descending depth in the state interval;

[0017] S33, obtaining the judgment result of the state interval of the hole-making tension and the hole-making descending depth of the current vibrator, when at least one state interval is in an abnormal state, issuing a first warning and going to step S4.

[0018] Further, in S32, the process of respectively detecting the state intervals of the hole-making tension and the hole-making descending depth of the current vibrator is as follows:

[0019] Detect whether the median value of the state interval of the hole-making tension of the current vibrator is in a decreasing state, and if so, determine that its state interval is in an abnormal state;

[0020] It is detected whether the median value of the state interval of the hole-making descending depth of the current vibrator is in an increasing state. If so, it is determined that the state interval is in an abnormal state.

[0021] Further, in S4, the process of real-time detection of whether the current time period reaches the maximum time allowed for the current hole making from the time point of the current descending point is specifically as follows:

[0022] Taking the time point of the current descent point as the starting point of the current time period and the real-time time point as the end point of the current time period, determine whether the time length of the current time period is equal to the maximum time length allowed for the current hole making. If so, change the current hole making state to the hole making stop state, control the winch to stop, and issue a second warning.

[0023] Furthermore, in S4, the process of obtaining the maximum allowable hole-making time of the current vibrator is specifically as follows:

[0024] The current hole-making speed of the current vibrator is obtained, and a maximum allowable hole-making time is calculated according to the vibrator head length of the current vibrator and the current hole-making speed.

[0025] A comprehensive monitoring device for vibro-hole making, characterized by comprising:

[0026] a memory for non-transitory storage of computer readable instructions;

[0027] The processor is used to execute the computer-readable instructions, and the computer-readable instructions, when executed by the processor, implement the comprehensive monitoring method for vibro-hole making.

[0028] 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 comprehensive monitoring method for vibro-fracturing is implemented.

[0029] Beneficial effects of the present invention:

[0030] The present invention provides a comprehensive monitoring method, device and medium for vibro-hole making, and relates to the technical field of soil layer drilling. The comprehensive monitoring method is mainly to solve the problem that the vibrator is prone to encounter cavities in loose strata during the current hole making process, thereby causing safety hazards. Safety monitoring is triggered by detecting the drop point of the hole making current. Based on the correlation between the hole making current, the hole making tension and the hole making drop depth, a first warning and a second warning are set in the hole making process. The first warning can quickly warn the operator to remind the operator to choose to control the stop of the winch to prevent safety hazards; the second warning can accurately control the stop of the winch to avoid the vibratory punch head completely entering the cavity, so that the present invention can realize intelligent and safe control of vibro-hole making under the dual warnings of the first warning and the second warning.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0043] Additionally, descriptions of well-known structures, functions, and configurations may be omitted for clarity and conciseness.One of ordinary skill in the art will recognize that various changes and modifications may be made to the examples described herein without departing from the spirit and scope of the present disclosure.

[0044] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0045] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0046] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments:

[0047] Example 1

[0048] During the hole-making process, the vibrator is usually lowered by controlling the winch. After it is lowered to the position to be vibrated, the vibrator is started to vibrate at the position to be vibrated, and the surrounding loose strata are compacted by vibration to achieve hole-making. Due to the complex distribution of the strata, the compaction of the strata corresponding to different hole-making depths is different. Moreover, when the strata are relatively loose, there may be some cavities in the strata corresponding to the hole-making depth. The cavities refer to the cavities that may exist in the strata.

[0049] When the vibrator encounters a loose stratum during the hole-making process, the vibrator penetrates the lower layer of stone through vibration and descends into the cavity without any restraint. The vibrator head of the vibrator is generally large. If the vibrator descending into the cavity is not intelligently and safely controlled in time, it will cause a major safety hazard. When the vibrator head completely enters the cavity, it is very easy to get stuck in the cavity, causing an accident.

[0050] Therefore, the present invention takes the above-mentioned special phenomenon into consideration, and aims to solve the problem that the vibrator is prone to encounter voids in loose strata during the current hole-making process, thereby causing safety hazards. In response to this special phenomenon, the present invention chooses to set a first warning and a second warning in the hole-making process based on the correlation between the hole-making current, the hole-making tension and the hole-making descent depth. The first warning can quickly issue a warning to the operator to remind the operator to choose to control the stop of the winch to prevent safety hazards; the second warning can accurately control the stop of the winch to prevent the vibrator head from completely entering the void, so that the present invention can achieve intelligent and safe control of vibratory hole-making under the dual warnings of the first warning and the second warning.

[0051] In this embodiment, the vibroflotation includes a drilling and hole-making stage of the soil layer, such as Figure 1 As shown, in the drilling and hole-making stage of the soil layer, under the control of the winch and the main machine, the vibrating head descends in the soil layer drilling hole to make a hole and vibrates the formation. When encountering a cavity in the formation, the vibrating head enters the cavity, and the hole-making current can be obtained in real time through the main machine, and the hole-making descent depth and the hole-making tension can be obtained in real time through the winch. The present invention mainly sends the acquired hole-making current, hole-making tension and hole-making descent depth to the controller. The controller analyzes the risk of the vibrating head encountering a cavity based on the correlation between the hole-making current, the hole-making tension and the hole-making descent depth, thereby automatically controlling or warning the drilling equipment to continue to descend, so as to prevent the safety problem of the equipment from getting stuck.

[0052] Specifically, a comprehensive monitoring method for vibro-hole drilling is provided based on the correlation between drilling current, drilling tension and drilling depth. Figure 2 As shown, the comprehensive monitoring method comprises the following steps:

[0053] S1, matching the current hole-making state. If the current hole-making state is a hole-making decreasing state, then in the current hole-making state, real-time detection is made on whether the hole-making current of the current vibrator decreases. If so, the hole-making current at this time point is marked as the current decreasing point, and the process goes to step S2;

[0054] S2. Detect the continuous state of the pore-forming current in real time from the current drop point. When the pore-forming current at several consecutive time points is within the minimum load interval, obtain the corresponding abnormal time period at the consecutive time points;

[0055] The minimum load interval refers to a preset value extended forward and backward by the minimum hole-making current, and the minimum hole-making current is the starting current for starting the vibrator to maintain vibration;

[0056] S3, extracting the state intervals of the hole-making tension and the hole-making descending depth of the current vibrator according to the abnormal time period, and performing change detection on the state interval according to the correlation between the hole-making tension and the hole-making descending depth and the hole-making current. If it is detected that the state interval is in an abnormal state, a first warning is issued, and the process goes to step S4;

[0057] S4. Obtain the current maximum allowable hole-making time of the current vibrator, and detect in real time from the time point of the current descent point whether the current time period reaches the current maximum allowable hole-making time. If so, change the current hole-making state to the hole-making stop state, control the winch to stop, and issue a second warning.

[0058] Specifically, the present invention records the hole-making current, hole-making tension and hole-making descending depth in real time when the hole-making current of the vibrator is in the descending state, that is, during the hole-making process of the vibrator. When it is detected that the hole-making current of the current vibrator is decreasing, a control instruction is issued to the winch based on the correlation between the hole-making current, hole-making tension and hole-making descending depth, such as Figure 3 As shown, the controller judges the obtained hole-making current, hole-making tension and hole-making descent depth. When the conditions are met, the controller sends a stop command to the winch, which can control the winch to stop.

[0059] When matching the current hole-making state, the hole-making state includes a hole-making descending state and a hole-making stopping state. The present invention proposes a comprehensive monitoring method for the hole-making descending state to realize intelligent and safe control of vibratory hole-making. Specifically, in actual conditions, if the current hole-making state is the hole-making descending state, the winch descends, and then controls the vibrator to descend to the waiting vibration position. When the vibrator reaches the vibration position, the vibrator is started to vibrate. At this time, the stratum and gravel around the vibrator will exert a certain restraining force on the vibrator, so that during the vibration of the vibrator, the hole-making current of the vibrator will increase, the hole-making descending depth of the vibrator will increase, and the hole-making tension of the vibrator will decrease; after the vibration of the vibrator ends, the winch controls the vibrator to rise to a height and insert it back to the next waiting vibration position. At this time, the vibrator has not started to vibrate. At this time, the hole-making current of the vibrator will decrease, the hole-making descending depth of the vibrator will decrease, and the hole-making tension of the vibrator will increase.

[0060] Specifically, during the hole-making process, the hole-making current, hole-making tension and hole-making descent depth corresponding to the vibrator can be recorded in real time. If no voids are encountered in the current hole-making process, the time in the hole-making process is divided according to the vibration retention interval, which is divided into multiple sequentially connected vibration retention intervals and non-vibration retention intervals. The changes in the hole-making current, hole-making tension and hole-making descent depth are displayed by the changes in the curves in the vibration retention interval and the non-vibration retention interval. The non-vibration retention interval is the time interval corresponding to the lifting and reverse insertion of the vibrator.

[0061] like Figure 3 As shown, it can be seen that when no voids are encountered during the hole-making process, the overall hole-making current value presents a sawtooth wave shape, and the hole-making current value increases in the vibration retention interval, such as [t1, t2]; the hole-making current value decreases in the non-vibration retention interval, such as [t2, t3]; and the hole-making current value of each vibrator has a minimum value, that is, the minimum hole-making current. The vibrator can be started to retain vibration only when the hole-making current value is greater than the minimum value. Therefore, when the hole-making current value is less than the minimum value, it can be indicated that the current vibrator is not performing the vibration retention work.

[0062] like Figure 4 As shown, it can be seen that when no voids are encountered during the hole-making process, the value of the hole-making tension in the vibration retention interval is in a decreasing state, such as [t1, t2]; the value of the hole-making tension in the non-vibration retention interval is in an increasing, decreasing, and then increasing state, such as [t2, t3]; specifically, during the vibration retention process, the vibrator descends, and the value of the hole-making tension will decrease; when the vibration retention is completed, the vibrator will be lifted to a height, and the value of the hole-making tension will increase; the vibrator is reversed, and the value of the hole-making tension will decrease; when the vibrator is reversed and contacts the bottom of the next vibration retention interval, the vibrator stops descending, and at this time, the value of the hole-making tension will increase by a part, thereby forming an increase, decrease, and then increase state.

[0063] like Figure 5 As shown, it can be seen that when no voids are encountered during the drilling process, the value of the drilling descent depth presents a sawtooth wave shape that descends in sequence. When the vibrator descends to the current vibration retention interval for retention vibration, during the vibration retention process, the vibrator will vibrate the loose strata around the pile hole to be formed into compaction. Due to the effect of vibration density, the vibrator will descend, causing the value of the drilling descent depth to rise finitely, that is, to rise by the depth of the current vibration retention interval, such as [t1, t2]; then, the vibrator is lifted up and reversed, causing the value of the drilling descent depth to fall finitely, that is, to fall to the next vibration retention interval, such as [t2, t3]; then, the next vibration retention interval is vibrated, causing the value of the drilling descent depth to rise finitely, that is, to rise to the depth of the vibration retention interval, such as [t3, t4].

[0064] The correlation between the pore-forming current and the pore-forming depth and pore-forming tension can be obtained: when the pore-forming current value increases, it means that the current vibrator starts to retain vibration. At this time, the pore-forming tension value will decrease, while the pore-forming depth value will increase; when the pore-forming current value decreases, it means that the current vibrator does not retain vibration, that is, the vibrator is lifted and reversed. At this time, the pore-forming tension value will increase, decrease, and then increase, while the pore-forming depth value will decrease.

[0065] Based on the above correlations between the borehole current and the borehole descent depth and the borehole pulling force, it can be concluded that when the vibrator encounters a cavity in a relatively loose stratum, the vibrator descends into the cavity. In the absence of the restraint of the surrounding strata and gravel, the borehole current will decrease and drop to the minimum value. As the vibrator descends, the borehole pulling force will also decrease, and the borehole descent depth will increase.

[0066] Specifically, the time interval when a cavity is encountered is also the interval without vibration retention. The changes in the curves in the interval with vibration retention and the time interval when a cavity is encountered can show the changes in the pore-forming current, pore-forming descent depth and pore-forming tension.

[0067] like Figure 6 As shown, it can be seen that when the vibrator drops to the first vibration retention interval [t1', t2'], the vibrator touches the corresponding bottom, and the current rises significantly, causing the value of the hole-making current in the first vibration retention interval to increase. When the vibrator in the first vibration retention interval encounters a cavity, the vibrator enters the cavity, and without the action of a restraining force, the value of the hole-making current begins to decrease, and a descending point is formed in the non-vibration retention interval [t2', t4'], that is, the value of the hole-making current at time t2'. Moreover, since the value of the hole-making current approaches the minimum value when the vibrator does not perform the vibration retention work, after the descending point, if the vibrator does not perform the vibration retention work, that is, when entering the cavity, the value of the hole-making current will drop to the minimum value and continue to be near the minimum value. The change of the hole-making current value in the non-vibration retention interval [t2', t4'] can be used to obtain that the vibrator currently encounters a cavity.

[0068] like Figure 7As shown, it can be seen that in the first vibration interval [t1', t2'], the value of the hole-making tension is decreasing, and in the non-vibration interval [t2', t4'], the vibrator encounters a cavity, that is, the vibrator enters the cavity. As the vibrator descends, the value of the hole-making tension will decrease again; and when no cavity is encountered, the vibrator is lifted and reversed. At this time, the value of the hole-making tension will increase, decrease, and increase again, instead of decreasing again. The different changes of the hole-making tension value in the corresponding non-vibration interval [t2', t4'] under different scenarios can prove that the current vibrator is still decreasing after encountering a cavity and has not stopped, indicating that the current vibrator is in an abnormal state and needs to be stopped by an operator or by forcibly controlling the winch.

[0069] like Figure 8 As shown, it can be seen that in the first vibration interval [t1', t2'], the value of the hole-making descent depth is in an upward state, while in the non-vibration interval [t2', t4'], the vibrator encounters a cavity, that is, the vibrator enters the cavity. As the vibrator descends, the value of the hole-making descent depth will continue to rise; in the case where no cavity is encountered, the vibrator is lifted up and reversed. At this time, the value of the hole-making descent depth will decrease instead of continuing to rise. The different changes in the hole-making descent depth values ​​in the corresponding non-vibration interval [t2', t4'] under different scenarios can prove that the current vibrator is still descending after encountering a cavity and has not stopped, indicating that the current vibrator is in an abnormal state and needs to be stopped by an operator or by forcibly controlling the winch.

[0070] Based on the above principle, the present invention chooses to trigger a comprehensive monitoring by detecting the falling point of the hole-making current. In the process of monitoring the hole-making of the vibrator, a first warning and a second warning are provided. The first warning can quickly issue a warning to the operator to remind the operator to choose to control the stop of the winch to prevent safety hazards; the second warning can accurately control the stop of the winch to prevent the vibrator head from completely entering the cavity, so that the present invention can realize intelligent and safe control of vibratory hole-making under the dual warnings of the first warning and the second warning.

[0071] In one embodiment, step S3 includes the following steps:

[0072] S31, extracting the state intervals of the hole-making tension and hole-making drop depth of the current vibrator according to the abnormal time period, wherein the state interval is composed of the values ​​of the hole-making tension / hole-making drop depth of the current vibrator recorded in real time during the abnormal time period;

[0073] S32, respectively detecting the state intervals of the current pore-forming tension and pore-forming descending depth of the vibrator, and judging whether the state interval is in an abnormal state according to the correlation between the pore-forming tension / pore-forming descending depth and the pore-forming current and the value of the pore-forming tension / pore-forming descending depth in the state interval;

[0074] Specifically, it is detected whether the median value of the state interval of the hole-making tension of the current vibrator is in a decreasing state, and if so, it is determined that its state interval is in an abnormal state; it is detected whether the median value of the state interval of the hole-making descending depth of the current vibrator is in an increasing state, and if so, it is determined that its state interval is in an abnormal state;

[0075] S33, obtaining the judgment result of the state interval of the hole-making tension and the hole-making descending depth of the current vibrator, when at least one state interval is in an abnormal state, issuing a first warning and going to step S4.

[0076] In order to effectively prevent the vibrating punch from completely entering the cavity, the present invention can also actively control the winch to stop after issuing the first warning, taking the time point of the current descent point as the starting point of the current time period and the real-time time point as the end point of the current time period to determine whether the time length of the current time period is equal to the maximum time length allowed for the current hole making. If so, the current hole making state is changed to the hole making stop state, and the winch is controlled to stop.

[0077] Furthermore, the process of obtaining the maximum allowed time of the current pore creation is as follows:

[0078] The current hole-making speed of the current vibrator is obtained, and a current maximum allowable hole-making time is calculated according to the current vibrator head length of the vibrator and the current hole-making speed. Specifically, a time length is obtained by dividing the vibrator head length by the current hole-making speed, and the time length minus the threshold value is used as the current time length. The time point of the current descent point is used as the starting point of the current maximum allowable hole-making time, and the current time length is extended backward to form the corresponding current maximum allowable hole-making time.

[0079] In one embodiment, in order to save computing power, after the first warning is issued, the operator can choose to control the winch to stop based on the first warning, that is, control the vibrator no longer to descend. After the operator issues a control stop instruction to the winch, an interrupt instruction can be generated according to the control stop instruction. The interrupt instruction can interrupt the process of executing step S4, and the second warning will no longer be issued, thereby avoiding repeated warnings.
