Description

Technical Field

[0001] This invention relates to the field of civil engineering materials technology, and more specifically to an adaptive control method for fiber-reinforced shotcrete formulations oriented towards service performance. Background Technology

[0002] Adaptive control of fiber-reinforced shotcrete formulations, geared towards service performance, refers to a process in which shotcrete is no longer based on a fixed mix proportion, but rather on the load-bearing capacity, crack resistance, impact resistance, and durability required by the structure during its service life. This involves dynamically adjusting the fiber type, dosage, water-cement ratio, and proportion of admixtures based on changes in the construction environment, evolution of stress conditions, and performance feedback. This ensures that the material properties continuously match actual needs as working conditions change, thereby guaranteeing both construction operability and stable and controllable comprehensive performance of shotcrete at different stages.

[0003] The existing technology has the following shortcomings: In the adaptive regulation of fiber-reinforced shotcrete formulations oriented towards service performance, as the pace of formulation adjustments continues to advance with changes in the construction environment, the original synergistic relationship between various influencing factors will gradually shift. When the water-cement ratio, fiber addition pace, and the intensity of admixtures fluctuate superimposedly within the same time period, the internal response relationship of the material will enter a critical state. At this point, even a small fluctuation in any factor will be rapidly amplified and transmitted to the overall performance level, causing multiple indicators such as fluidity, adhesion, and early strength to deviate from the control range simultaneously. This can trigger a sudden decline in overall performance or even instability and collapse in a short period of time, which is difficult to recover through conventional adjustment methods.

[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive control method for fiber-reinforced shotcrete formulations oriented towards service performance, thereby addressing the problems in the aforementioned background art. To achieve the above objective, this invention provides the following technical solution: an adaptive control method for fiber-reinforced shotcrete formulations oriented towards service performance, comprising the following steps: The spraying rate, back-rebound ratio, initial setting time difference, surface fall-off amount, and environmental disturbance frequency values ​​of fiber shotcrete were obtained during the dynamic control process of the fiber shotcrete formula. They were then arranged in a uniform time sequence to form synchronous fluctuation segments, which were used to characterize the synchronous change of multiple indicators during the service performance-oriented control process. For the synchronous fluctuation segment, the increase or decrease jump difference value between adjacent time moments is extracted. The positions where multiple indicators synchronously reach the preset critical range are time-series located and rearranged according to the order of arrival to form a critical approach segment, which is used to mark the coupling instability precursor in the dynamic control process of fiber shotcrete formula. Based on the critical approach segment, the abnormal jump difference values ​​in subsequent time steps are forward-compressed, the high mutation segment is divided into multiple progressive transition segments, and the formula delivery rewriting interval is shortened simultaneously to form a gradually advancing segment, which is used to reduce the degree of synchronous deviation of multiple performance indicators. By implementing segmented transfer processing of the fluctuation rebound amount in the subsequent injection process through the gradual advancement segment, the change share that has reached the preset critical range first is transferred to the low-sensitivity segment, and the control weight relationship is redistributed according to the time sequence to form staggered and dispersed segments, which are used to weaken the synchronous instability and aggregation trend. New fluctuation values ​​are continuously introduced along the staggered peak segments. The trend of offset increase exceeding the preset change threshold is reversed and the sudden increase within a unit time period is divided into multiple stages of gradual increase and decrease. This maintains the time-sharing stable convergence state of various performance indicators of fiber shotcrete during the continuous control process.

[0006] Preferably, the ejection rate, re-attachment ratio, initial condensation time difference, surface fall-off amount, and environmental disturbance frequency are processed by uniform temporal order arrangement and continuous aggregation to characterize the synchronous change relationship of multiple indicators and construct corresponding segments of synchronous fluctuations. The steps are as follows: The ejection rate, re-attachment ratio, initial condensation time difference, surface fall-off amount, and environmental disturbance frequency value are obtained at each recording moment during continuous spraying operations. The five types of values ​​at each recording moment are then grouped into the same recording unit. The recording units at the same time are arranged in sequence and the values ​​of ejection rate, re-attachment ratio, initial condensation time difference, surface fall amount, and environmental disturbance frequency are kept in a fixed order. For individual values ​​that are missing at a corresponding time, the result of the adjacent previous recording time is used to continue recording. Continue to mark the change direction of the results of the continuous unfolding, and mark the values ​​of ejection rate, re-attachment ratio, initial condensation time difference, surface fall amount and environmental disturbance frequency as rising, falling or remaining, respectively. Subsequently, the recorded units with the same time after being marked are grouped together. Recording times with consistent synchronous fluctuations of multiple indicators are grouped into the same segment, and the corresponding values ​​and change states are retained to obtain the corresponding segments of synchronous fluctuations.

[0007] Preferably, after marking the change direction of the ejection rate value, re-attachment ratio value, initial condensation time difference value, surface fall amount value, and environmental disturbance frequency value within the same recording unit, the change state within each recording unit is read in the order of recording time. The synchronous increase relationship between the ejection rate value and the re-attachment ratio value within the same recording time is identified, and the change state of the initial condensation time difference value and the surface fall amount value is synchronously associated. Recording times in which the synchronous increase relationship is continuously maintained are grouped into the same segment.

[0008] Preferably, by performing jump difference extraction and critical location processing on the corresponding segments of synchronous fluctuations, the temporal relationship of synchronous changes of multiple indicators is identified and critical approach segments are constructed. The steps are as follows: Read the ejection rate, re-attachment ratio, initial condensation time difference, surface fall-off amount, and environmental disturbance frequency values ​​of adjacent moments in the corresponding synchronous fluctuation segment, and extract the corresponding increase / decrease jump difference values. Compare the allowable fluctuation ranges of the increase / decrease jump difference value with the allowable fluctuation ranges of the ejection rate value, the allowable fluctuation range of the back-attachment ratio value, the allowable fluctuation range of the initial condensation time difference value, the allowable fluctuation range of the surface receding amount value, and the allowable fluctuation range of the environmental disturbance frequency value, and record the position where multiple indicators simultaneously enter the boundary interval. The positions of synchronous entry into the boundary interval were identified, and the sequential relationships of the increase / decrease difference values ​​of ejection rate, re-attachment ratio, initial condensation time difference, surface fall-off amount, and environmental disturbance frequency were marked. All timing location results are organized and arranged in chronological order to obtain the critical approach segment.

[0009] Preferably, when performing time-series positioning on the location that synchronously enters the boundary interval, the entry time corresponding to the value of the increase or decrease in ejection rate is marked as the leading time, and the entry time corresponding to the value of the increase or decrease in reattachment ratio, the value of the increase or decrease in initial condensation time difference, and the value of the increase or decrease in surface fall amount is marked as the following time. At the same time, the entry time corresponding to the value of the frequency of environmental disturbance is marked as the leading time of external disturbance, and the entry times are arranged in the order of entry.

[0010] Preferably, by performing forward compression and progressive splitting on the abnormal jump values ​​corresponding to the critical approach segment, the synchronous deviation of multiple indicators is reduced and a progressively advancing segment is constructed. The steps are as follows: Read the ejection rate increase / decrease jump value, the reattachment ratio increase / decrease jump value, the initial condensation time difference increase / decrease jump value, the surface fall amount increase / decrease jump value, and the environmental disturbance frequency increase / decrease jump value at the corresponding recording time of the critical approach segment, identify the abnormal jump area and collect the abnormal change set. The abnormal change values ​​of ejection rate, back-retention ratio, initial condensation time difference, surface fall-off amount, and environmental disturbance frequency are separated from the abnormal change set, and the abnormal change values ​​are transferred to the previous time sequence. The values ​​of increase / decrease in ejection rate, increase / decrease in reabsorption ratio, increase / decrease in initial condensation time, increase / decrease in surface fallback amount, and increase / decrease in environmental disturbance frequency after the arrangement and transfer are classified into the gradual transition zone and the formula application rewriting interval is adjusted. Merge the results of each change in the progressive transition section and receive the newly added corresponding values, maintaining the order of progressive changes to obtain the gradually advancing segment.

[0011] Preferably, when splitting the abnormal jump values ​​of ejection rate, the abnormal jump values ​​of ejection rate are allocated to continuous recording time points, and the direction of change is kept consistent; the abnormal jump values ​​of re-attachment ratio and abnormal jump values ​​of surface fall are split simultaneously, and the corresponding changes are moved forward to adjacent recording time points respectively; merging processing is performed in the progressive order of the jump values ​​of ejection rate increase / decrease, jump values ​​of re-attachment ratio increase / decrease, jump values ​​of initial condensation time difference increase / decrease, jump values ​​of surface fall, and jump values ​​of environmental disturbance frequency increase / decrease, so as to maintain the continuous change state in the gradual advancement segment.

[0012] Preferably, by performing segmented transfer and control allocation processing on the fluctuation rebound amount corresponding to the gradual advancement segment, the synchronous changes of multiple indicators are dispersed and staggered dispersion segments are constructed. The steps are as follows: Read the ejection rate increase / decrease jump value, the rebound ratio increase / decrease jump value, the initial condensation time difference increase / decrease jump value, the surface fall amount increase / decrease jump value, and the environmental disturbance frequency increase / decrease jump value at the corresponding recording time of the slow advance segment, and collect the fluctuation rebound amount. The rebound volume is divided into the ejection rate rebound volume, the back-retention ratio rebound volume, the initial condensation time difference rebound volume, the surface fall volume rebound volume, and the environmental disturbance frequency rebound volume. The change share entering the allowable fluctuation boundary range is transferred in segments and then shifted to the subsequent recording time. Adjust the rebound amount of ejection rate fluctuation, rebound amount of retraction ratio fluctuation, rebound amount of initial condensation time difference fluctuation, rebound amount of surface fall amount fluctuation, and rebound amount of environmental disturbance frequency fluctuation after the shift, and redistribute the control weight relationship according to the magnitude of the change. The system receives the rebound amount of newly added ejection rate fluctuations, rebound amount of rebound amount of rebound ratio fluctuations, rebound amount of rebound amount of initial condensation time difference fluctuations, rebound amount of rebound amount of surface fall fluctuations, and rebound amount of rebound amount of environmental disturbance frequency fluctuations. It maintains the relationship between the control priorities and performs the shift and arrangement to obtain staggered and dispersed segments.

[0013] Preferably, the ejection rate fluctuation rebound amount entering the allowable fluctuation boundary range is divided into a front segment change share, a middle segment change share, and a rear segment change share, and the middle segment change share is shifted to the next recording time; the middle and rear segment change shares of the rebound amount of the backlash ratio fluctuation are shifted to the second to last recording time, and the initial condensation time difference fluctuation rebound amount, surface receding amount fluctuation rebound amount, and environmental disturbance frequency fluctuation rebound amount are split and shifted in the same direction.

[0014] Preferably, by performing reverse traction processing on the fluctuation values ​​corresponding to the staggered and dispersed segments, the offset expansion trend is weakened and time-sharing stable convergence is maintained. The steps are as follows: Read the ejection rate, reattachment ratio, initial condensation time difference, surface fall rate, and environmental disturbance frequency values ​​corresponding to the recorded time of the staggered dispersion segment, identify the continuous expansion state, and collect the offset trend set. The following states are defined in the offset trend set: continuous expansion of ejection rate, continuous expansion of retraction ratio, continuous expansion of initial condensation time difference, continuous expansion of surface fall-off amount, and continuous expansion of environmental disturbance frequency. Preset change thresholds are compared and the over-threshold segments are recorded. The changes in ejection rate, re-attachment ratio, initial condensation time difference, surface fall rate, and environmental disturbance frequency in the super-threshold section were separated, and sudden increases were transformed into gradual increases, and sudden decreases were transformed into gradual decreases. The system receives newly added ejection rate values, re-attachment ratio values, initial condensation time difference values, surface fall-off values, and environmental disturbance frequency values, and arranges them in a gradually increasing and gradually decreasing order to maintain a time-sharing stable convergence state.

[0015] The technical effects and advantages provided by the present invention in the above technical solution are as follows: This invention reorders the ejection rate, re-attachment ratio, initial condensation time difference, surface fall rate, and environmental disturbance frequency values ​​in a unified manner and constructs corresponding synchronous fluctuation segments. During continuous control, it can fully reflect the synchronous change relationship between multiple indicators. Furthermore, it can locate the precursors of coupling instability in advance through critical approach segments, thereby completing the identification and intervention before the performance deviation extends to the overall level. This transforms the control process from a passive response to a proactive guidance, improves the ability to control the linkage changes of multiple indicators, and maintains the continuous stability of the control process.

[0016] This invention releases abnormal jumps and fluctuation rebounds in segments by using gradual advancement segments and staggered dispersion segments. In subsequent stages, it transforms sudden increases into gradual increases and sudden decreases into gradual decreases through reverse traction processing. This allows various performance indicators to advance in stages at different recording times, avoiding concentrated shifts in multiple indicators within the same time period. This reduces the risk of synchronous instability and clustering, and maintains an orderly convergence of performance changes during continuous regulation, thereby enhancing the stability and sustainability of the overall regulation process. Attached Figure Description

[0017] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in this invention. For those skilled in the art, other drawings can be obtained based on these drawings.

[0018] Figure 1 This is a flowchart of the adaptive control method for fiber-reinforced shotcrete formulation based on service performance, as described in this invention. Detailed Implementation

[0019] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of this disclosure will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art.

[0020] This invention provides, for example Figure 1 The adaptive control method for fiber-reinforced shotcrete formulations, oriented towards service performance, includes the following steps: The spraying rate, back-rebound ratio, initial setting time difference, surface fall-off amount, and environmental disturbance frequency values ​​of fiber shotcrete were obtained during the dynamic control process of the fiber shotcrete formula. They were then arranged in a uniform time sequence to form synchronous fluctuation segments, which were used to characterize the synchronous change of multiple indicators during the service performance-oriented control process. In the dynamic control of fiber-reinforced shotcrete formulation for service performance orientation, spraying rate, backfill ratio, initial setting time difference, surface fall-off amount, and environmental disturbance frequency are all included in the same time frame and processed according to a unified time sequence to form synchronous fluctuation segments. These segments are used to characterize the synchronous change of multiple indicators during the service performance orientation control process. The specific steps are as follows: After the dynamic control of the fiber-reinforced shotcrete formula is initiated, each recording moment in the continuous shotcreting operation is used as a data acquisition node. The spraying rate, back adhesion ratio, initial setting time difference, surface fall-off amount, and environmental disturbance frequency are recorded at each recording moment. The spraying rate is taken from the amount of shotcrete output per unit time at that recording moment. The back adhesion ratio is taken from the ratio between the amount of adhesive remaining on the working surface after shotcreting and the amount of shotcrete. The initial setting time difference is taken from the time difference between the corresponding batch at that recording moment from shotcreting to reaching the initial setting state. The surface fall-off amount is taken from the amount that moves down or falls off the working surface after shotcreting at that recording moment. The environmental disturbance frequency is taken from the actual number of temperature fluctuations, humidity fluctuations, airflow disturbances, water seepage on the working surface, and changes in spraying distance that occur in the continuous time period before and after that recording moment. In this way, a synchronous recording unit containing five types of values ​​is formed at each recording moment, ensuring that the five types of values ​​have consistent time assignment.

[0021] Each synchronous recording unit is arranged in chronological order according to its recording time, and within each synchronous recording unit, the values ​​of ejection rate, re-attachment ratio, initial condensation time difference, surface fall amount, and environmental disturbance frequency are maintained in a fixed order. After the synchronous recording units of the previous recording time are arranged, the synchronous recording units of the next recording time are arranged in succession, so that a continuous time chain is formed between different recording times. During the arrangement process, for individual values ​​that are missing a corresponding time, the recording result of the previous recording time adjacent to that individual value is used as the continuation record, and its source time is marked to avoid the five types of values ​​deviating from the unified time order due to inconsistent collection intervals. Through the above processing, the values ​​of ejection rate, re-attachment ratio, initial condensation time difference, surface fall amount, and environmental disturbance frequency have a corresponding position at each recording time.

[0022] After the unified time sequence is completed, the five types of values ​​are marked as rising, falling, or remaining constant according to the direction of change between adjacent recording times. When the ejection rate value is greater than the previous recording time in the later recording time, it is marked as rising; when the return ratio value is less than the previous recording time in the later recording time, it is marked as falling; and when the initial condensation time difference value is the same for two consecutive recording times, it is marked as remaining constant. The surface receding amount value and the frequency of environmental disturbances are marked in the same way, and the five types of state marks are rewritten into the corresponding synchronous recording units. Then, the five types of state marks in each synchronous recording unit are read in the order of recording time to identify the combination of changes in the five types of values ​​that rise together, fall together, or alternate between partial rise and partial fall within the same recording time, thereby converting the change of a single value into a synchronous fluctuation relationship of multiple indicators.

[0023] Each synchronous recording unit with its changed state is fragmented and grouped according to continuous recording time. When the synchronous fluctuation relationship of multiple indicators between two consecutive recording times maintains the same combination form, they are grouped into the same segment. When the synchronous fluctuation relationship of multiple indicators changes at a later recording time, a new segment is established starting from the later recording time, and subsequent synchronous recording units are received. Each segment retains its start recording time, end recording time, all ejection rate values, backflow ratio values, initial condensation time difference values, surface fall-off values, environmental disturbance frequency values, and corresponding change states, thus forming synchronous fluctuation corresponding segments. Synchronous fluctuation corresponding segments can present the synchronous rise and fall, alternating fluctuation, and continuous maintenance states of five types of values ​​during the dynamic control of the formula in a unified time sequence, which is used to characterize the synchronous change state of multiple indicators during the service performance-oriented control process.

[0024] For the synchronous fluctuation segment, the increase or decrease jump difference value between adjacent time moments is extracted. The positions where multiple indicators synchronously reach the preset critical range are time-series located and rearranged according to the order of arrival to form a critical approach segment, which is used to mark the coupling instability precursor in the dynamic control process of fiber shotcrete formula. After forming the corresponding segments of synchronous fluctuations, the numerical changes between adjacent moments are continuously extracted, and the ejection rate, recapture ratio, initial condensation time difference, surface fall rate, and environmental disturbance frequency are included in the same time series judgment range. By performing time series localization on the positions where multiple indicators synchronously reach the preset critical range, a critical approaching segment that can mark the precursors of coupling instability is formed. The specific process is as follows: For the values ​​in the synchronous fluctuation segment arranged in a uniform time sequence, the ejection rate, re-attachment ratio, initial condensation time difference, surface receding amount, and environmental disturbance frequency values ​​are read sequentially between two adjacent time points. The increase / decrease difference between the later and earlier time points is then extracted. Specifically, when the ejection rate at the later time point is higher than that at the earlier time point, the difference is recorded as the ejection rate increment; when the ejection rate at the later time point is lower than that at the earlier time point, the difference is recorded as the ejection rate decrease. The re-attachment ratio, initial condensation time difference, surface receding amount, and environmental disturbance frequency values ​​are then used to generate corresponding increase / decrease difference values. Through this processing, the synchronous change state of multiple indicators originally arranged by time in the synchronous fluctuation segment is further transformed into a continuous jump difference change result between adjacent time points.

[0025] After obtaining the increase / decrease difference values ​​between adjacent time points, the increase / decrease difference values ​​for each type of indicator are compared item by item with the corresponding preset critical ranges. The preset critical ranges include the allowable fluctuation ranges for ejection rate, retracement ratio, initial condensation time difference, surface receding amount, and environmental disturbance frequency. When the increase / decrease difference value of ejection rate within the same adjacent time interval enters the boundary interval of the allowable fluctuation range of ejection rate, and at least two of the increase / decrease difference values ​​of retracement ratio, initial condensation time difference, surface receding amount, and environmental disturbance frequency simultaneously enter the boundary interval of their respective allowable fluctuation ranges, this adjacent time interval is recorded as the position where multiple indicators simultaneously reach the preset critical range. This position also retains the corresponding start time, end time, the name of the indicator entering the preset critical range, and the increase / decrease difference value of each indicator.

[0026] For locations where multiple recorded indicators simultaneously reach preset critical ranges, time-series localization is performed based on their occurrence times within the corresponding synchronous fluctuation segments. The order in which each indicator reaches its preset critical range at each location is then organized. When the ejection rate increment / decrease value enters the corresponding preset critical range first, followed by the repatriation ratio increment / decrease value, initial condensation time difference increment / decrease value, or surface receding amount increment / decrease value, the entry time corresponding to the ejection rate value is recorded as the leading time, and the entry times of subsequent indicators entering the preset critical range are recorded as the following times. When the environmental disturbance frequency value enters the corresponding preset critical range first, the entry time corresponding to the environmental disturbance frequency value is used as the external disturbance leading time, and the entry times of other indicators within the same time period are arranged in chronological order. In this way, each location simultaneously reaching its preset critical range generates a time-series localization result with a chronological order.

[0027] All time-series positioning results are rearranged according to their order of occurrence. The positions where multiple indicators first synchronously reach the preset critical range are placed first, followed by the positions that appear subsequently. Each rearranged position retains the corresponding values ​​for the increase / decrease in spray rate, increase / decrease in backfill ratio, increase / decrease in initial setting time difference, increase / decrease in surface receding amount, increase / decrease in environmental disturbance frequency, the time of entering the preset critical range, and the order in which the indicators entered. After rearrangement, several consecutive positions with consistent order are grouped into the same segment, and the position where the order changes is used as the starting point of a new segment, thus forming a critical approach segment. The critical approach segment can mark the continuous change trajectory of multiple indicators from a synchronous fluctuation state to a critical state in the time progression, and is used to mark the coupling instability precursors in the dynamic control process of fiber-reinforced shotcrete formulation.

[0028] Based on the critical approach segment, the abnormal jump difference values ​​in subsequent time steps are forward-compressed, the high mutation segment is divided into multiple progressive transition segments, and the formula delivery rewriting interval is shortened simultaneously to form a gradually advancing segment, which is used to reduce the degree of synchronous deviation of multiple performance indicators. After the critical approach segment is formed, the abnormal jump values ​​in subsequent time periods are forward-compressed, and the sudden changes that occur in a continuous time period are split into multiple continuous advancement time periods. At the same time, the formula delivery rewriting interval is shortened to form a gradual advancement segment. This is used to reduce the synchronous deviation of values ​​such as ejection rate, re-attachment ratio, initial condensation time difference, surface fall-off amount, and frequency of environmental disturbances within the same time period. The specific process is as follows: Along the continuous recording timelines following the end of the critical approach segment, the values ​​of ejection rate increase / decrease, retracement ratio increase / decrease, initial condensation time difference increase / decrease, surface fall rate increase / decrease, and environmental disturbance frequency increase / decrease are sequentially read, and the changes between the current and previous times are compared item by item in the order of recording time. When the ejection rate increase / decrease value at the current time exceeds the continuous change range of the ejection rate increase / decrease value at the previous time, the current ejection rate increase / decrease value is recorded in the abnormal change zone. When the retracement ratio increase / decrease value reverses direction between two consecutive recording times, and the change after the direction reversal is... When the amount exceeds the cumulative value of the previous two changes, the current increase or decrease in the condensation time difference is recorded in the abnormal jump zone. When the increase or decrease in the condensation time difference expands over a period of time in consecutive recording moments, and the expansion exceeds the maximum change in the previous three consecutive recording moments, the current increase or decrease in the condensation time difference is classified into the abnormal jump zone. The increase or decrease in the surface fall amount and the increase or decrease in the frequency of environmental disturbances are identified in the same way. Thus, an abnormal change set containing multiple abnormal jump values ​​is formed within the same recording moment, and the recording moment, change direction, and change duration corresponding to each abnormal jump value are recorded.

[0029] For the abnormal fluctuation values ​​of ejection rate, retracement ratio, initial condensation time difference, surface receding amount, and environmental disturbance frequency in the abnormal change set, a forward compression process is performed to split and transfer the abnormal changes that originally appeared in a single recording moment to the preceding recording moment. When the duration of the ejection rate abnormal fluctuation value in a certain recording moment is shorter than the average duration of the three consecutive preceding recording moments, the current ejection rate abnormal fluctuation value is split into three consecutive change segments and inserted into the three consecutive recording moments before the current recording moment. When the retracement ratio abnormal fluctuation value is accompanied by the surface receding amount abnormal fluctuation value in the same recording moment, the retracement ratio abnormal fluctuation value and the surface receding amount abnormal fluctuation value are split synchronously in the same direction and moved forward to the previous recording moment and the two previous recording moments, respectively. The initial condensation time difference abnormal fluctuation value and the environmental disturbance frequency abnormal fluctuation value are also subjected to continuous splitting processing in the same way, thereby transforming the concentrated abnormal changes in a single recording moment into a progressive change state in multiple recording moments.

[0030] After completing the forward compression process, the ejection rate increase / decrease, re-attachment ratio increase / decrease, initial condensation time difference increase / decrease, surface fall-off amount increase / decrease, and environmental disturbance frequency increase / decrease values, which had been split into multiple recording times, were rearranged according to the recording time sequence. Recording times with continuously increasing changes from small to large were assigned to the same asymptotic transition zone. When the ejection rate increase / decrease value maintained an increasing change over four consecutive recording times, these four recording times were assigned to the first asymptotic transition zone. When the re-attachment ratio increase / decrease and the initial condensation time difference remained relatively constant at their respective recording times... When the order of increase is the same, the corresponding recording time is synchronously assigned to the first progressive transition segment. Then, the values ​​of the increase / decrease difference in surface fall amount and the increase / decrease difference in environmental disturbance frequency in subsequent recording times are read and assigned to the corresponding progressive transition segments according to the same change order. After the progressive transition segment is formed, the formula delivery rewriting action, which was originally performed once every multiple recording time periods, is adjusted to be performed once every one recording time period. The direction of change after each rewriting is kept consistent with the direction of change in the corresponding progressive transition segment, so that the change process of multiple indicators in continuous recording time forms a step-by-step advancement state.

[0031] The system continuously receives data on the ejection rate increase / decrease, retraction ratio increase / decrease, initial condensation time difference increase / decrease, surface fall rate increase / decrease, and environmental disturbance frequency increase / decrease from subsequent recording times along the progressive transition section. This data is then continuously merged according to the progressive changes already established within the progressive transition section. When a new ejection rate increase / decrease value in a subsequent recording time aligns with the direction of the final change in the current progressive transition section, the new ejection rate increase / decrease value is appended to the end of the current progressive transition section. When a new retraction ratio increase / decrease value is opposite to the direction of change in the current progressive transition section, the new retraction ratio increase / decrease value is placed at the beginning of a new progressive transition section. The initial condensation time difference increase / decrease, surface fall rate increase / decrease, and environmental disturbance frequency increase / decrease values ​​are continuously merged in the same manner, thus forming a progressively advancing segment that runs through the continuous recording time. The progressive segment can break down the synchronous deviation changes that were originally concentrated in the same recording time into continuous progressive changes in multiple recording times, and maintain the time-division progressive relationship between the ejection rate value, re-attachment ratio value, initial condensation time difference value, surface fall amount value, and environmental disturbance frequency value.

[0032] By implementing segmented transfer processing of the fluctuation rebound amount in the subsequent injection process through the gradual advancement segment, the change share that has reached the preset critical range first is transferred to the low-sensitivity segment, and the control weight relationship is redistributed according to the time sequence to form staggered and dispersed segments, which are used to weaken the synchronous instability and aggregation trend. After forming a gradually advancing segment, the fluctuation and rebound during subsequent ejection processes are continuously segmented and transferred. Based on the temporal progression within the gradually advancing segment, the proportions of change among ejection rate, rebound ratio, initial condensation time difference, surface fall, and environmental disturbance frequency are redistributed. By shifting the proportion of change reaching the preset critical range to the less sensitive segment and rearranging the control priorities at different recording times, a staggered and dispersed segment is formed to weaken the synchronous instability trend caused by the aggregation of multiple indicators within the same time period. The specific process is as follows: Along the continuous recording time points corresponding to the gradually advancing segments, the values ​​of the ejection rate increase / decrease, the backfill ratio increase / decrease, the initial condensation time difference increase / decrease, the surface fall-off amount increase / decrease, and the environmental disturbance frequency increase / decrease are sequentially read, and the fluctuation rebound amount in each recording time point is collected; when the ejection rate increase / decrease changes from rising to falling between two consecutive recording time points, the change difference in this change segment is recorded as the ejection rate fluctuation rebound amount; when the backfill ratio increase / decrease changes from falling to rising in continuous recording time points... When the temperature rises, the corresponding change difference is recorded as the rebound amount of the reflux ratio fluctuation. The values ​​of the increase / decrease difference of the initial condensation time difference, the increase / decrease difference of the surface receding amount, and the increase / decrease difference of the frequency of environmental disturbance are respectively formed into the corresponding rebound amounts in the same way. Then, according to the order of the recording time, the rebound amounts of the ejection rate fluctuation, the rebound amount of the reflux ratio fluctuation, the rebound amount of the initial condensation time difference fluctuation, the rebound amount of the surface receding amount fluctuation, and the rebound amount of the frequency of environmental disturbance in the same recording time are arranged into the same recording interval, thereby forming the rebound set within the corresponding recording time.

[0033] For each fluctuation rebound quantity in the fluctuation rebound set, a segmented transfer process is performed, and the change fraction that first reaches the preset critical range is identified according to the continuous advancement relationship in the progressively advancing segment. When the ejection rate fluctuation rebound quantity enters the allowable fluctuation boundary range of ejection rate at the current recording time, the current ejection rate fluctuation rebound quantity is divided into the first segment change fraction, the middle segment change fraction, and the last segment change fraction, and the middle segment change fraction is shifted to the next recording time. When the backlash ratio fluctuation rebound quantity enters the allowable fluctuation boundary range of backlash ratio simultaneously at the same recording time, the last segment change fraction of the backlash ratio fluctuation rebound quantity is shifted to the second subsequent recording time. The initial condensation time difference fluctuation rebound quantity, surface receding amount fluctuation rebound quantity, and environmental disturbance frequency fluctuation rebound quantity are all processed by the same method of change fraction splitting, and the change fraction that enters the preset critical range is shifted to the subsequent recording time in sequence. Through this process, multiple change fractions that were originally concentrated in the same recording time are split and released in different recording times.

[0034] After completing the shift of change shares, the ejection rate fluctuation rebound, backlash ratio fluctuation rebound, initial condensation time difference fluctuation rebound, surface receding amount fluctuation rebound, and environmental disturbance frequency fluctuation rebound, which have been split into different recording times, are re-arranged in time, and the control priority is redistributed according to the magnitude of the change in each recording time. When the ejection rate fluctuation rebound in a certain recording time is greater than the backlash ratio fluctuation rebound, the recording time is assigned to the ejection rate priority control segment, and the control proportion corresponding to the backlash ratio fluctuation rebound in the same recording time is reduced. When the initial condensation time difference fluctuation rebound exceeds the surface receding amount fluctuation rebound in a subsequent recording time, the corresponding recording time is assigned to the initial condensation time difference priority control segment, and the surface receding amount control advancement proportion in that recording time is reduced. The environmental disturbance frequency fluctuation rebound participates in the priority allocation processing in continuous recording times in the same way, so that the change shares of different indicators form an alternating advancement state in different recording times.

[0035] The system continuously receives new ejection rate fluctuation rebounds, backfill ratio fluctuation rebounds, initial condensation time difference fluctuation rebounds, surface receding amount fluctuation rebounds, and environmental disturbance frequency fluctuation rebounds along the redistributed continuous recording time. These are then continuously merged according to the control priority at the current recording time. When a new ejection rate fluctuation rebound enters the ejection rate priority control segment, it is moved to the end of that segment, and the corresponding shift time for the backfill ratio fluctuation rebound is simultaneously delayed. When a new initial condensation time difference fluctuation rebound enters the initial condensation time difference priority control segment, it is continued to be moved to the end of the current segment, and the release time for the surface receding amount fluctuation rebound is simultaneously delayed. The backfill ratio fluctuation rebound, surface receding amount fluctuation rebound, and environmental disturbance frequency fluctuation rebound are continuously shifted and arranged in the same manner, thus forming staggered and dispersed segments. The staggered distribution segment can split multiple synchronous change shares that were originally concentrated in the same recording time into different recording times and release them sequentially, while maintaining the time-division progression relationship between the ejection rate value, re-attachment ratio value, initial condensation time difference value, surface fall amount value, and environmental disturbance frequency value, in order to weaken the synchronous instability aggregation trend.

[0036] New fluctuation values ​​are continuously introduced along the staggered and dispersed segments. The trend of the offset increase continuously exceeding the preset change threshold is subjected to reverse traction processing. The sudden increase change within a unit time period is divided into a multi-stage gradual increase change, and the sudden decrease change within a unit time period is divided into a multi-stage gradual decrease change, so as to maintain the time-sharing stable convergence state of various performance indicators of fiber shotcrete in the continuous control process. After forming the staggered peak dispersion segment, ejection rate, recapture ratio, initial condensation time difference, surface fall rate, and environmental disturbance frequency are continuously introduced along the continuous recording time. Following the time progression relationship within the staggered peak dispersion segment, reverse traction processing is applied to trends where the offset increase continuously exceeds a preset threshold. By splitting and transferring sudden increases and decreases occurring within a unit time period, the change process across multiple recording times remains in a continuous and gradual state, thereby maintaining the time-sharing stable convergence state of various performance indicators during continuous control. The specific steps are as follows: Along the continuous recording times corresponding to the staggered peak dispersion segments, the newly added ejection rate value, re-attachment ratio value, initial condensation time difference value, surface fall-off value, and environmental disturbance frequency value are sequentially read and written into the current recording interval according to the recording time order. After the newly added ejection rate value is written into the current recording interval, the ejection rate change difference between the current recording time and the previous, second, and third recording times is continuously read and arranged in chronological order to form a continuous change chain. When the ejection rate change direction in three consecutive recording times is all upward, and the ejection rate change difference in the current recording time is greater than that in the previous recording time... When the ejection rate changes by a certain value, the current ejection rate change state is recorded as the ejection rate continuous expansion state. When the direction of change of the return ratio in three consecutive recording times is all decreasing, and the difference in the return ratio change in the current recording time is greater than the difference in the return ratio change in the previous recording time, the current return ratio change state is recorded as the return ratio continuous expansion state. The initial condensation time difference value, the surface receding amount value, and the environmental disturbance frequency value are respectively used to form the corresponding continuous expansion state, and the change direction, the cumulative change interval, and the change duration in the corresponding recording time are recorded respectively, thereby forming the offset trend set in the continuous recording time.

[0037] For the continuous expansion states of ejection rate, return ratio, initial condensation time difference, surface fall, and environmental disturbance frequency in the offset trend set, a preset change threshold comparison is performed. When the cumulative change of the continuous expansion state of ejection rate over four consecutive recording times exceeds the allowable change range of ejection rate, the current continuous expansion state of ejection rate is classified into the ejection rate exceeding threshold segment; when the cumulative change of the continuous expansion state of return ratio over four consecutive recording times exceeds the allowable change range of return ratio, the current continuous expansion state of return ratio is classified into the return ratio exceeding threshold region. When the cumulative change in the initial condensation time difference during four consecutive recording times exceeds the allowable range of change in the initial condensation time difference, the current continuous expansion state of the initial condensation time difference is classified into the initial condensation time difference over-threshold segment. The continuous expansion states of surface fall and environmental disturbance frequency are formed into corresponding over-threshold segments in the same manner. Subsequently, the over-threshold segments of ejection rate, fallback ratio, initial condensation time difference, surface fall, and environmental disturbance frequency in the same recording time are arranged into the same continuous recording chain and arranged in a continuous sequence according to the order of appearance of each over-threshold segment.

[0038] Reverse traction processing is performed along the ejection rate exceeding threshold, backflow ratio exceeding threshold, initial condensation time exceeding threshold, surface fall exceeding threshold, and environmental disturbance frequency exceeding threshold segments in the continuous arrangement relationship. When the ejection rate change in the ejection rate exceeding threshold segment increases continuously within a single recording moment, the ejection rate change at the current recording moment is split into a first-stage change, a second-stage change, and a third-stage change, and inserted into three consecutive recording moments after the current recording moment, respectively. The first-stage change is written to the next recording moment, the second-stage change is written to the next two recording moments, and the third-stage change is written to the next three recording moments. The recording time is used to transform the concentrated upward change in a single recording time into a continuous, gradual upward change in multiple recording times. When the change in the retracement ratio in the threshold section continuously decreases in a single recording time, the decrease in the retracement ratio in the current recording time is split into multiple continuously decreasing segments, and written into multiple subsequent recording times, so that the originally concentrated sudden drop change is transformed into a continuous, gradual decrease in multiple recording times. The changes in initial condensation time difference, surface fall amount, and environmental disturbance frequency are split and transferred in the same way, and the direction of change after splitting is kept consistent with the original direction of change.

[0039] Along the continuous recording time after the completion of the reverse traction processing, newly added ejection rate values, backflow ratio values, initial condensation time difference values, surface receding amount values, and environmental disturbance frequency values ​​are continuously received, and sequentially arranged according to the gradual increase and decrease order in the current recording time. When the newly added ejection rate value is consistent with the current gradual increase direction, the newly added ejection rate value is placed at the end of the current gradual increase, and the recording time of the decrease corresponding to the backflow ratio value is simultaneously delayed. When the newly added initial condensation time difference value is consistent with the current gradual decrease direction, the newly added initial condensation time difference value is placed at the end of the current gradual decrease, and the recording time of the increase corresponding to the surface receding amount value is simultaneously delayed. The backflow ratio value, surface receding amount value, and environmental disturbance frequency value are continuously sequentially arranged in the same way, so that the ejection rate value, backflow ratio value, initial condensation time difference value, surface receding amount value, and environmental disturbance frequency value maintain an alternating state in the continuous recording time, and maintain the time-sharing stable convergence state of various performance indicators in the continuous control process.

[0040] This invention reorders the ejection rate, re-attachment ratio, initial condensation time difference, surface fall rate, and environmental disturbance frequency values ​​in a unified manner and constructs corresponding synchronous fluctuation segments. During continuous control, it can fully reflect the synchronous change relationship between multiple indicators. Furthermore, it can locate the precursors of coupling instability in advance through critical approach segments, thereby completing the identification and intervention before the performance deviation extends to the overall level. This transforms the control process from a passive response to a proactive guidance, improves the ability to control the linkage changes of multiple indicators, and maintains the continuous stability of the control process.

[0041] This invention releases abnormal jumps and fluctuation rebounds in segments by using gradual advancement segments and staggered dispersion segments. In subsequent stages, it transforms sudden increases into gradual increases and sudden decreases into gradual decreases through reverse traction processing. This allows various performance indicators to advance in stages at different recording times, avoiding concentrated shifts in multiple indicators within the same time period. This reduces the risk of synchronous instability and clustering, and maintains an orderly convergence of performance changes during continuous regulation, thereby enhancing the stability and sustainability of the overall regulation process.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
