Description

Technical Field

[0001] The invention relates to the technical field of bridge deck maintenance construction management, and in particular to a construction management method suitable for maintenance of cement concrete bridge decks in seasonally frozen areas. Background Art

[0002] Since bridge diseases are common in seasonally frozen areas, bridge decks need to be maintained. However, the maintained bridge decks still have problems such as cracks, honeycomb surfaces, and steel bar corrosion, which not only reduce the bearing capacity of the bridge deck but may even cause bridge deck rupture accidents. Therefore, effective repair and maintenance are needed to alleviate or prevent the disease from continuing to develop and causing damage to bridge deck components.

[0003] For example, the invention patent with announcement number CN114819212B is a method for dynamically dividing asphalt pavement maintenance sections that takes spatial continuity into account. It changes the critical value for the level division of road condition assessment sub-indicators from a fixed value to a fuzzy cross-interval range; and based on this, it dynamically merges and divides sections that are continuous in space and have similar disease severity, to solve the problem that the existing fixed-length assessment unit cannot make full use of automated detection data, resulting in the road condition assessment unit being too long to cover up the poor road condition of local sections, and the problem that the distribution of maintenance sections in the same belt is discrete and not conducive to the organization of special maintenance construction. The application can more accurately evaluate the use status of highway pavements, which is conducive to the targeted proposal of special maintenance plans, easy construction organization, and maintaining the performance of road pavement.

[0004] For example, the invention patent with announcement number CN117455122B is a road condition assessment method, device, electronic device and storage medium, which relates to the field of highway maintenance technology. The method includes: obtaining assessment data of each target dimension of the road section to be assessed, and each target dimension includes construction condition dimension, traffic load dimension, road surface material dimension, meteorological dimension, roadbed condition dimension and maintenance frequency dimension; based on the target weight value corresponding to each target dimension and the assessment data of each target dimension, obtaining the road condition assessment result of the road section to be assessed, and the target weight value corresponding to each target dimension is obtained based on the hierarchical analysis method, entropy method and minimum distance function. The provided road condition assessment method, device, electronic device and storage medium can better adapt to changes in the external environment state, can more accurately reflect the actual state of the road surface, have more superior flexibility, objectivity, interpretability and adaptability, and can provide a more accurate reference basis for road maintenance.

[0005] In combination with the above technical solutions, it is found that there is a problem of imprecise management in the current management of road conditions. At the same time, multiple data are not used as data support for road construction, which will lead to inaccurate road assessment, which is not conducive to the subsequent construction management of road maintenance, and will reduce the bearing capacity of the road surface, affecting the safe use of the road surface.

[0020] Figure 1 It is a schematic diagram of the method flow of the present invention. DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] In a specific embodiment, the present invention provides a construction management method suitable for the maintenance of cement concrete bridge decks in seasonally frozen areas. First, the treatment status of the bridge deck to be maintained for paving and chiseling operations is determined, and then the milling construction completion status of the maintained bridge deck is implemented, and finally material construction is performed on the maintained bridge deck, thereby realizing the maintenance operation of the bridge deck. The above process can improve the bearing capacity of the bridge deck and reduce the occurrence of bridge deck fracture accidents, thereby ensuring the quality and safety of the bridge deck.

[0023] Reference Figure 1 As shown, the present invention provides a construction management method suitable for maintenance of cement concrete bridge decks in seasonally frozen areas, including: step one, bridge deck pavement chiseling treatment: performing pavement chiseling operations on the bridge deck that needs maintenance, and evaluating the pavement chiseling treatment degree corresponding to the bridge deck that needs maintenance; if the pavement chiseling treatment degree corresponding to the bridge deck that needs maintenance is greater than a preset pavement chiseling treatment threshold, then execute step two, and record the bridge deck that needs maintenance as a maintenance bridge deck; if the pavement chiseling treatment degree corresponding to the bridge deck that needs maintenance is less than or equal to the preset pavement chiseling treatment threshold, then continue to execute this step.

[0024] In this example embodiment, the above-mentioned pavement removal processing threshold is extracted from the bridge deck maintenance management platform, which represents the minimum value of the pavement removal processing. The specific value needs to be determined according to the scale of the bridge deck maintenance and the efficiency of the pavement removal equipment used.

[0025] It needs to be explained that the above-mentioned bridge deck maintenance management platform is a collection of fixed values ​​such as reference values ​​and thresholds used in bridge deck maintenance and construction management. The website of the relevant traffic management department can be viewed to extract information on bridge deck maintenance and construction management and related data, and the analyzable values ​​can be integrated into a database, which is thus recorded as a bridge deck maintenance management platform.

[0026] Specifically, the pavement chiseling degree corresponding to the bridge deck that needs maintenance is analyzed in the following process:

[0027] By performing pavement chiseling operations on the bridge deck that needs maintenance, the corresponding operation information of each pneumatic pick within the set chiseling cycle and the corresponding operation information of each seam cutter within the set chiseling cycle are obtained.

[0028] It needs to be explained that the above-mentioned chiseling cycle is the length of time used in the process of pavement chiseling of the bridge deck that requires maintenance. The specific value will be adjusted according to influencing factors such as the size of the bridge deck and the operating efficiency of the chiseling equipment.

[0029] According to the corresponding operating information of each pneumatic pick within the set chiseling cycle, including the average air source pressure, the average impact force and the maximum pressure that the pick can withstand, the linear regression model is used to analyze the operating intensity of each pneumatic pick belonging to the bridge deck that needs maintenance.

[0030] It needs to be explained that the above-mentioned average air source pressure is obtained by real-time monitoring through the pressure sensor installed on the pneumatic pick, and the average of the collected air source pressure data is taken to obtain the average air source pressure within the chiseling cycle; the average impact force is obtained by using the impact force sensor on the pneumatic pick, collecting the number of times the pneumatic pick is used within the chiseling cycle, and averaging the impact force data collected each time to obtain the average impact force of the chiseling cycle; the maximum pressure that the pick can withstand is obtained by using a pressure sensor to monitor the pressure on the pick during the chiseling cycle in actual operation of the pneumatic pick, and finding the maximum value to determine the maximum pressure that the pick can withstand during the chiseling cycle.

[0031] In this embodiment, the specific analysis process of the working force of each pneumatic pick belonging to the bridge deck to be maintained is as follows:

[0032] Firstly, the mean air source pressure, mean impact force and maximum pressure of the pick corresponding to each pneumatic pick within the set chiseling cycle are taken as independent variables, and the operating intensity of each pneumatic pick belonging to the bridge deck that needs maintenance is taken as the dependent variable; by using the established linear regression model, by inputting the independent variable data such as the mean air source pressure, mean impact force and maximum pressure of each pneumatic pick belonging to the bridge deck, the operating intensity of each pneumatic pick is predicted through the data evaluation function of the linear regression model, so as to obtain the operating intensity of each pneumatic pick belonging to the bridge deck that needs maintenance.

[0033] According to the corresponding operation information of each seam cutter within the set chiseling cycle, the number of cutting times, the bridge deck area corresponding to each cutting, and the average cutting depth are extracted, and the operating intensity of each seam cutter belonging to the bridge deck that needs maintenance is obtained through a vector regression model.

[0034] It should be explained that the method of obtaining the above-mentioned number of cuts can be achieved through the counter on the cutting machine; the method of obtaining the bridge deck area is to use a measuring tool to measure the length and width of the cut after each cut, and thus calculate the area of ​​the bridge deck; the process of obtaining the average cutting depth is to measure the cutting depth through the depth sensor on the cutting machine after each cut, accumulate the depth value of each cut, and finally divide it by the number of cuts to get the average cutting depth.

[0035] In this example embodiment, the calculation formula for the above bridge deck area is usually 50cm*50cm=2500cm 2 .

[0036] In this embodiment, the specific analysis process of the operating intensity of each seam cutting machine belonging to the bridge deck to be maintained is as follows:

[0037] The number of cuts, bridge deck area, and average cutting depth are taken as independent variables, and the operating intensity of each seam cutter belonging to the bridge deck that needs maintenance is taken as the dependent variable; tools such as open source libraries are used to establish and train the vector regression model; the established vector regression model is evaluated to test the fitting effect and accuracy of the model; the established vector regression model is used to input independent variable data such as the number of cuts, bridge deck area, and average cutting depth, and the multidimensional relationship between the independent variables is considered to predict the operating intensity of each seam cutter belonging to the bridge deck that needs maintenance.

[0038] The pneumatic pick treatment index corresponding to the bridge deck that needs maintenance and the seam cutter treatment index corresponding to the bridge deck that needs maintenance are analyzed, and the pavement chiseling treatment degree corresponding to the bridge deck that needs maintenance is obtained by adding them up.

[0039] In this embodiment, the pneumatic pick processing index corresponding to the bridge deck to be maintained is analyzed as follows:

[0040] The pneumatic pick operating intensity of the bridge deck that needs maintenance is multiplied by the weight factor corresponding to the pneumatic pick operating intensity, and the pneumatic pick treatment index corresponding to the bridge deck that needs maintenance is obtained comprehensively. The weight factor corresponding to the pneumatic pick operating intensity is obtained by using historical data to analyze the impact of different pneumatic pick operating intensities on bridge deck maintenance, and the weight factor is obtained through data analysis and statistical methods; it represents the weight importance of different pneumatic pick operating intensities; its numerical range is usually [0,1].

[0041] In this embodiment, the analysis process of the seam cutter processing index corresponding to the bridge deck to be maintained is as follows:

[0042] The operating intensity of each seam cutter belonging to the bridge deck that needs maintenance is multiplied by the weight factor corresponding to the operating intensity of the seam cutter, and the seam cutter processing index corresponding to the bridge deck that needs maintenance is obtained comprehensively, wherein the weight factor corresponding to the operating intensity of the seam cutter is obtained according to the degree of influence of different operating intensities of the seam cutters on the maintenance of the bridge deck, combined with expert evaluation and data analysis, and the weight factor corresponding to the operating intensity of the seam cutter is obtained comprehensively; it represents the weight importance of different operating intensities of the seam cutters; the value is between 0 and 1, and is specified as 0.32 in this embodiment.

[0043] In a specific embodiment, the present invention can quantitatively evaluate the quality of the chiseling operation by performing pavement chiseling operations on the bridge deck that needs maintenance, and assess the pavement chiseling treatment degree corresponding to the bridge deck that needs maintenance, so as to timely obtain whether the quality of the chiseling work meets the requirements of the specifications, thereby ensuring that a clean and flat foundation can be provided for the maintenance materials during subsequent maintenance construction, thereby ensuring the firmness of the combination of the maintenance materials and the bridge deck.

[0044] Step 2. Determination of bridge deck milling construction: Collect the construction data of the bridge deck maintenance within the set construction milling cycle, and determine the completion degree of the bridge deck milling construction. If the completion degree of the bridge deck milling construction is greater than the preset milling construction completion threshold, execute step 3. If the completion degree of the bridge deck milling construction is less than or equal to the preset milling construction completion threshold, continue to execute this step.

[0045] In this example embodiment, the above-mentioned milling construction completion threshold is extracted from the bridge deck maintenance management platform, representing the specific situation of the milling construction completion, and the specific value is adjusted and changed according to factors such as the loss and power of each milling construction equipment.

[0046] Specifically, the pavement construction management assessment value of the bridge deck maintenance is analyzed in the following process:

[0047] According to the construction data of the bridge deck maintenance within the set construction milling cycle, the construction data includes paving construction data and milling construction data.

[0048] It should be explained that the above-mentioned construction milling cycle is the duration between the start time point and the end time point of the bridge deck milling construction. The specific value will be adjusted according to the milling plan of the bridge deck and the operating efficiency of the corresponding construction equipment.

[0049] Through the paving construction data of the maintained bridge deck within the set construction milling cycle, the beam surface removal area of ​​the roughening machine within the set construction milling cycle and the total paving height of the paver within the set construction milling cycle were extracted, and the paving construction management evaluation value of the maintained bridge deck was obtained through regression analysis model processing.

[0050] It needs to be explained that the above-mentioned beam surface clearance area is obtained by calculating the actual cleaned surface area based on the working width, working depth and working time of the roughening machine, so as to determine the beam surface clearance area; the total paving height is obtained by monitoring the total height of the materials actually laid by the paver during the construction process to determine the total paving height.

[0051] In this embodiment, the above-mentioned pavement construction management evaluation value of the bridge deck maintenance is specifically processed as follows:

[0052] A regression analysis model was established based on the beam surface clearance area of ​​the roughening machine, the total paving height of the paver, and other factors that may affect the operational efficiency. The established regression model was trained and verified using the collected data, and the model's fit and accuracy were evaluated to ensure that the model could effectively predict the operational efficiency value of the bridge deck paving construction equipment. Finally, the regression analysis model was used to predict and evaluate the beam surface clearance area and the total paving height within the set construction milling cycle to obtain the paving construction management evaluation value.

[0053] Furthermore, the milling construction management evaluation value of the bridge deck maintenance is specifically analyzed as follows:

[0054] By maintaining the milling construction data of the bridge deck within the set construction milling cycle, the milling times of the milling machine within the set construction milling cycle, the milling depth corresponding to each milling time and the milling lap width are obtained, wherein the milling times are obtained by tracking the milling times through the counter of the milling machine, and the milling depth is obtained by obtaining the depth of each milling through the depth adjustment device on the milling machine; the milling lap width is obtained by controlling the milling lap width by adjusting the working width and working mode of the milling machine, thereby obtaining the milling lap width.

[0055] The milling reference depth and milling overlap reference width are extracted from the bridge deck maintenance management platform to obtain the milling construction management evaluation value of the bridge deck maintenance. In a specific embodiment, the various influencing data of the milling construction can be predicted and analyzed through a random forest model to obtain data on the degree of milling construction management of the bridge deck maintenance.

[0056] In this embodiment, the above-mentioned milling construction management evaluation value of the bridge deck maintenance is obtained by comprehensively analyzing the milling depth and the milling overlap width, and the milling construction management evaluation value of the bridge deck maintenance is finally obtained. The more accurate algorithm is as follows:

[0057]

[0058] Wherein, β2 represents the evaluation value of the milling construction management of the bridge deck maintenance. In this embodiment, if the number of milling times is inappropriate, the milling depth and the milling overlap width of each milling will not be within the standard value range, which will make the surface of the bridge deck uneven, seriously leading to a decrease in the bearing capacity of the bridge, and at the same time increase the rework cost, resulting in low construction efficiency. Therefore, it is necessary to conduct a comprehensive analysis of the operation process of the milling machine. Since the algorithm is simplified, this expression can be made more compact, which makes it easy to integrate the milling construction management of the bridge deck, and ultimately ensure the milling construction quality and safety of the bridge deck maintenance.

[0059] ΔXH represents the milling reference depth, which is an adaptation value specified when analyzing the milling depth of each milling by the milling machine. In this example embodiment, the specific value is 4 mm.

[0060] XH b It indicates the milling depth corresponding to the bth milling of the milling machine within the set construction milling cycle, which is the milling depth of the milling machine each time.

[0061] ΔXD represents the reference width of the milling overlap, which is an adaptation value specified when analyzing the milling overlap width of each milling by the milling machine. In this example embodiment, the value is 5 mm.

[0062] XD b It indicates the milling overlap width corresponding to the bth milling of the milling machine within the set construction milling cycle, which is the overlap width of each milling of the milling machine.

[0063] n2 represents the correction factor corresponding to the preset milling depth, n3 represents the correction factor corresponding to the preset milling overlap width, b represents the number of each milling, b=1,2,3,...,u, u represents the total number of milling times.

[0064] In this example embodiment, the correction factor corresponding to the milling depth and the correction factor corresponding to the milling lap width can be obtained by extracting them based on analyzing the historical construction data of the milling machine; the correction factor corresponding to the milling depth represents the degree of correction of the milling depth performed by the milling machine, and the value range is [0,1]; the correction factor corresponding to the milling lap width represents the degree of correction of the milling lap width performed by the milling machine, and the value is 0.57.

[0065] Specifically, the completion degree of the milling construction of the bridge deck maintenance is analyzed in the following process:

[0066] The pavement construction management evaluation value of the maintained bridge deck is analyzed and extracted, and the pavement construction management evaluation index of the maintained bridge deck is obtained by multiplying the evaluation value with the weight factor corresponding to the pavement construction management evaluation value.

[0067] In this example embodiment, the weight factor corresponding to the above-mentioned paving construction management evaluation value can be obtained by using statistical methods based on the historical paving construction data of the bridge deck; it represents the weight importance of the paving construction management evaluation value in the paving construction management evaluation index; the value in this embodiment is specified to be 0.52.

[0068] The milling construction management assessment value of the bridge deck maintenance is analyzed and extracted, and the milling construction management assessment index of the bridge deck maintenance is obtained by multiplying the milling construction management assessment value with the weight factor corresponding to the milling construction management assessment value.

[0069] In this example embodiment, the weight factor corresponding to the above-mentioned milling construction management evaluation value can be obtained from the milling construction management evaluation report; it represents the weight of the milling construction management evaluation value in the milling construction management evaluation index; the value range is [0,1].

[0070] The paving construction management evaluation index of the bridge deck maintenance and the milling construction management evaluation index of the bridge deck maintenance are added together to obtain the completion degree of the milling construction of the bridge deck maintenance.

[0071] In a specific embodiment, the present invention can monitor the construction progress and quality of the bridge deck in real time by collecting construction data of the bridge deck maintenance, determine the completion degree of the milling construction of the bridge deck maintenance, help to promptly discover problems in the construction process and solve them, and reduce the phenomenon of bridge deck maintenance and reinforcement recurrence due to substandard construction quality.

[0072] Step 3: Bridge deck construction compliance management: Monitor the material construction status of the bridge deck maintenance within the set material paving cycle, evaluate the material construction compliance of the bridge deck maintenance, and conduct feedback management on the construction compliance status of the bridge deck maintenance.

[0073] Furthermore, the mixing management evaluation index corresponding to the asphalt mixture for maintaining the bridge deck is specifically analyzed as follows:

[0074] By monitoring the material construction status of the bridge deck maintenance within the set material paving cycle, we can obtain the mixing data of the asphalt mixture of the bridge deck maintenance within the set material mixing cycle, the transportation data within the set material transportation cycle, the paving data within the set material paving cycle, and the compaction data within the set material compaction cycle.

[0075] It needs to be explained that the above-mentioned material paving cycle refers to the duration of the entire process from material production to use, which is a combination of material mixing cycle, material transportation cycle, material spreading cycle and material compaction cycle; the material mixing cycle is the time from the beginning to the end of mixing of asphalt mixture, and the specific value will be adjusted with the operating efficiency of the mixing equipment; the material transportation cycle is the time from the beginning to the end of transportation of asphalt mixture, and the specific value will be adjusted with the scale of transportation equipment and other influencing factors; the material spreading cycle is the time from the beginning to the end of paving of asphalt mixture, and the specific value will be adjusted with the scale of the bridge deck and the number of paving personnel; the material compaction cycle is the time from the beginning to the end of compaction of asphalt mixture, and the specific value will be adjusted with the quality of asphalt mixture and the number of compaction personnel.

[0076] According to the mixing data of the asphalt mixture for maintaining the bridge deck within the set material mixing cycle, the corresponding tack coat oil consumption, the corresponding spraying amount of the asphalt spreader and the mixing floor damper opening of the mixer within the set material mixing cycle are extracted.

[0077] It needs to be explained that the method of obtaining the above-mentioned tack coat oil dosage is based on the experience and practice of the construction personnel, combined with the specific project conditions, so as to determine the dosage of the tack coat oil; the spraying amount can be directly measured by the metering equipment of the asphalt spreader; the air door opening of the mixing plant can be adjusted in real time according to the actual situation in the mixing process and the mixing quality requirements, so as to obtain the air door opening of the mixing plant.

[0078] The influencing index of tack coat oil consumption corresponding to the set material mixing cycle of the asphalt mixture for maintaining the bridge deck, the influencing index of the average spreading speed corresponding to the asphalt spreader and the influencing index of the air door opening of the mixing tower corresponding to the mixer obtained by comprehensive analysis are added together and recorded as the mixing management evaluation index corresponding to the asphalt mixture for maintaining the bridge deck.

[0079] The analysis process of the corresponding tack oil consumption in the set material mixing cycle for the asphalt mixture used to maintain the bridge deck is as follows:

[0080] The tack coat oil dosage and the tack coat oil adaptation dosage corresponding to the asphalt mixture for maintaining the bridge deck within the set material mixing cycle are analyzed and processed to obtain the tack coat oil dosage influence index corresponding to the asphalt mixture for maintaining the bridge deck within the set material mixing cycle.

[0081] In this exemplary embodiment, the above-mentioned suitable amount of tack coat oil is determined by laboratory tests and experiments, wherein the specific analysis process of the tack coat oil amount affecting the index is as follows:

[0082] Set appropriate evaluation standards, compare and analyze the actual amount of tack oil used with the adapted amount, and compare the construction quality, adhesion performance and other indicators under different amounts. Based on the analysis results, the influencing indicators of tack oil amount are obtained.

[0083] The analysis process of the average spreading speed of the asphalt spreader corresponding to the asphalt mixture for maintaining the bridge deck within the set material mixing cycle is as follows:

[0084] The spraying volume of the asphalt spreader for maintaining the bridge deck within the set material mixing cycle is ratio-processed with the duration corresponding to the material mixing cycle to obtain the average spreading speed of the asphalt spreader for maintaining the bridge deck within the set material mixing cycle. The ratio is then multiplied by the influence factor of the unit value corresponding to the average spreading speed to obtain the influence index of the average spreading speed of the asphalt spreader for maintaining the bridge deck within the set material mixing cycle.

[0085] In this example embodiment, the influencing factor of the unit value corresponding to the above average spreading speed can be obtained by comprehensive evaluation based on the historical operation data of the spreading vehicle, which represents the influence degree of the average spreading speed of the spreading vehicle, and the specific value range is [0, 1].

[0086] The analysis process of the influence index of the air door opening of the mixing plant corresponding to the mixer during the set material mixing cycle of the asphalt mixture for maintaining the bridge deck is as follows:

[0087] The influence index of the air door opening of the mixing tower corresponding to the mixer of the asphalt mixture for maintaining the bridge deck within the set material mixing cycle is obtained by ratio operation with the limiting value of the air door opening of the mixing tower.

[0088] In this example embodiment, the method for obtaining the above-mentioned threshold value of the air door opening of the mixing plant can be based on a comprehensive analysis of the historical data of the air door opening of the mixing plant of the mixer to determine the threshold value of the air door opening of the mixing plant.

[0089] Specifically, the transportation management evaluation index corresponding to the asphalt mixture for maintaining the bridge deck is analyzed in the following specific process:

[0090] According to the transportation data corresponding to the asphalt mixture for maintaining the bridge deck within the set material transportation cycle, the transportation data includes the factory transportation temperature and the on-site transportation temperature at each material transportation time point.

[0091] It should be explained that the above-mentioned factory transportation temperature and on-site transportation temperature may be obtained by using a temperature sensor.

[0092] It is further necessary to explain that the above-mentioned material transportation time points are obtained by randomly arranging material transportation cycles as material transportation time points, thereby obtaining the material transportation time points by statistics.

[0093] The factory transportation adaptation temperature and the on-site transportation definition temperature are extracted from the bridge deck maintenance management platform, and finally the transportation management evaluation index corresponding to the asphalt mixture for maintaining the bridge deck is obtained. In a specific embodiment, the transportation management evaluation index corresponding to the asphalt mixture can be analyzed through a transportation risk assessment model.

[0094] In this embodiment, the transportation management evaluation index corresponding to the above asphalt mixture has a more accurate algorithm, and its expression is as follows:

[0095]

[0096] Wherein, μ is the transportation management evaluation index corresponding to the asphalt mixture used to maintain the bridge deck. In this embodiment,

[0097] If the factory transportation temperature of the asphalt mixture is not within the appropriate temperature range, the viscosity of the asphalt mixture will change, which will not only affect the temperature of subsequent on-site transportation, but also require additional temperature control equipment and measures during on-site transportation, increasing the transportation management cost of materials. As a result, the transportation management evaluation index fluctuates greatly, further reducing the construction performance of the maintained bridge deck, and ultimately resulting in the poor durability of the maintained bridge deck. Therefore, it is very important to effectively manage and control the transportation temperature of the asphalt mixture. At the same time, this algorithm will improve the original complex form and make it more in line with the needs of transportation management evaluation. It can not only reduce transportation costs accordingly, but also improve the transportation management capabilities of the maintained bridge deck.

[0098] ΔYC is the factory transportation adaptation temperature, which is an appropriate value specified when analyzing the factory transportation temperature of the asphalt mixture. In this example embodiment, the specific value is 175 degrees.

[0100] YX d It is the on-site transportation temperature of the asphalt mixture for maintaining the bridge deck at the dth material transportation time point, indicating the transportation temperature of the asphalt mixture during the transportation process on site.

[0101] ΔYX is the on-site transportation limiting temperature, which is the minimum value specified when analyzing the on-site transportation temperature of asphalt mixture. In this example embodiment, the specific value is 185 degrees.

[0102] f1 is the correction factor corresponding to the preset factory transportation temperature, f2 is the correction factor corresponding to the preset on-site transportation temperature, d is the number of each material transportation time point, d = 1, 2, 3, ..., r, r is the total number of material transportation time points, and e is a natural constant.

[0103] In this example embodiment, the correction factor corresponding to the above-mentioned factory transportation temperature is obtained by statistics of historical material temperature data, representing the degree of correction of the change in factory transportation temperature, and the value range is [0,1]; the correction factor corresponding to the on-site transportation temperature is obtained by statistics of historical material temperature data, representing the degree of correction of the change in on-site transportation temperature, and the value is defined as 0.96.

[0104] In this embodiment, the values ​​of the transportation management evaluation index corresponding to the asphalt mixture for maintaining the bridge deck are shown in Table 1:

[0105] Table 1 Transportation management evaluation index corresponding to asphalt mixture for bridge deck maintenance

[0106] d Factory transportation temperature / degrees On-site transportation temperature / degrees μ 1 170 170 15.61 2 175 170 88.53 3 180 173 15.6 4 182 178 11.92 5 185 190 8.87

[0107] Among them, the correction factor corresponding to the factory transportation temperature is 0.5.

[0108] Furthermore, the paving management evaluation index corresponding to the asphalt mixture for maintaining the bridge deck is specifically analyzed as follows:

[0109] According to the paving data of the asphalt mixture for maintaining the bridge deck within the set material paving cycle, where the paving data includes the preheating temperature of the ironing plate at the starting time of the material paving cycle, the maximum vibration frequency and the maximum vibration amplitude within the material paving cycle, the initial compaction degree of the ironed bridge deck corresponding to the ironing plate for maintaining the bridge deck is obtained through the random forest regression model.

[0110] It should be explained that the above-mentioned preheating temperature is obtained by using a temperature sensor; the maximum vibration frequency is obtained by using a frequency sensor; the maximum vibration amplitude can be obtained by installing a vibration sensor on the ironing plate, and the maximum vibration amplitude can be analyzed and calculated through the data collected by the vibration sensor.

[0111] In this embodiment, the analysis process of the initial compaction degree of the smoothed bridge deck is as follows:

[0112] First, it is necessary to collect the preheating temperature, maximum vibration frequency and maximum vibration amplitude of the ironing plate for maintaining the bridge deck at the beginning time of the material paving cycle as a data set; use the collected data to establish a random forest regression model; divide the data set into a training set and a test set, use the training set to train the random forest model, use the test set to evaluate the performance of the model, and use the random forest model to get the importance ranking of each performance, determine the contribution of the preheating temperature, maximum vibration frequency and maximum vibration amplitude in predicting the initial compaction of the ironed bridge deck, and finally predict the initial compaction of the ironed bridge deck.

[0113] The initial compaction influence index of the ironing plate for the bridge deck maintenance, the average paving speed influence index of the paver for the bridge deck maintenance and the average feeding speed influence index of the chain feeder for the bridge deck maintenance are added together, and the final value obtained is the paving management evaluation index corresponding to the asphalt mixture for the bridge deck maintenance.

[0114] In this embodiment, the analysis process of the initial compaction impact index of the bridge deck corresponding to the above-mentioned bridge deck maintenance screed is as follows:

[0115] The initial compaction degree of the smoothed bridge deck corresponding to the smoothing plate for maintaining the bridge deck is multiplied by the weight factor corresponding to the initial compaction degree of the smoothed bridge deck to obtain the initial compaction influence index of the smoothed bridge deck corresponding to the smoothing plate for maintaining the bridge deck.

[0116] In this example embodiment, the weight factor corresponding to the initial compaction degree of the smoothed bridge deck is obtained by a statistical method based on the numerical change of the initial compaction degree of the smoothed bridge deck, and the value is set to 0.25.

[0117] In this embodiment, the average paving speed corresponding to the paver for maintaining the bridge deck mentioned above affects the index, and the analysis process is as follows:

[0118] The average paving speed corresponding to the paver within the set material paving cycle is obtained, and analyzed and processed with the paving speed adaptation value, and finally the average paving speed influence index corresponding to the paver for maintaining the bridge deck is obtained.

[0119] In this example embodiment, the above-mentioned method for obtaining the average paving speed is a speed sensor, and the method for obtaining the paving speed adaptation value is obtained based on the historical paving speed statistics of the paver, which represents the appropriate value of the paving speed, and the specific value is 2m / min. The specific analysis process of the paving average speed influencing index is as follows:

[0120] A linear regression model is used to establish a prediction model for the index affecting the average paving speed. The data correlation between the average paving speed and the paving speed adaptation value is analyzed based on the established prediction model to obtain the index affecting the average paving speed.

[0121] In this embodiment, the mean value of the feeding speed corresponding to the chain plate feeder for maintaining the bridge deck affects the index, and the analysis process is as follows:

[0122] The average feeding speed of the chain plate feeder corresponding to the set material paving cycle is obtained, and data processing is performed with the feeding speed adaptation value to obtain the average feeding speed influence index corresponding to the chain plate feeder for maintaining the bridge deck.

[0123] In this example embodiment, the above-mentioned method for obtaining the mean value of the feeding speed is a speed sensor, and the method for obtaining the feeding speed adaptation value is obtained based on the historical feeding speed statistics of the chain plate feeder, which represents the reference value of the feeding speed, wherein the specific analysis process of the feeding speed mean value affecting the index is as follows:

[0124] A random forest model is used to establish a prediction model for the influencing index of the mean feeding speed. According to the established prediction model, the data association between the mean feeding speed and the feeding speed adaptation value is analyzed to obtain the influencing index of the mean feeding speed.

[0125] Specifically, the compaction management evaluation index corresponding to the asphalt mixture for maintaining the bridge deck is analyzed in the following specific process:

[0126] According to the compaction data of the asphalt mixture for maintaining the bridge deck within the set material compaction cycle, the number of rolling times, the average rolling speed of each rolling and the average rolling vibration frequency of the rolling equipment within the set material compaction cycle are extracted.

[0127] It needs to be explained that the above-mentioned number of rolling times is obtained by a counter; the average rolling speed is obtained by a speed sensor; and the average rolling vibration frequency is obtained by a vibration sensor.

[0128] At the same time, the corresponding inclined rolling control angle of the rolling equipment within the set material compaction cycle is obtained by installing a laser rangefinder on the rolling equipment to monitor the inclination of the rolling equipment in real time, thereby obtaining the data of the inclined rolling control angle.

[0129] The rolling speed adaptation value, rolling vibration adaptation frequency and oblique rolling control angle reference value are extracted from the bridge deck maintenance management platform, and finally the compaction management evaluation index corresponding to the asphalt mixture of the bridge deck maintenance is obtained. In a specific embodiment, the compaction influence data can be processed by the multi-layer neural network in the neural network model to predict the compaction management evaluation index.

[0130] In this embodiment, the compaction management evaluation index corresponding to the asphalt mixture for maintaining the bridge deck has a more accurate algorithm for analysis, and its specific expression is as follows:

[0131]

[0132] Wherein, θ is the compaction management evaluation index corresponding to the asphalt mixture for maintaining the bridge deck. In this embodiment,

[0133] A higher rolling average speed is often accompanied by a higher rolling vibration frequency. When the vibration frequency of the rolling equipment is too high, the rolling equipment's control of the oblique rolling angle is inaccurate. Therefore, if the rolling average speed, rolling vibration average frequency, and oblique rolling control angle of the rolling equipment are not within a reasonable range, the compaction effect of the rolling equipment will be poor, and the rolling operation efficiency will be low, which will further lead to the value of the compaction management evaluation index of the asphalt mixture not being within the ideal range. Therefore, it is necessary to analyze the rolling average speed, rolling vibration average frequency, and oblique rolling control angle of the rolling equipment in detail. At the same time, when processing the above large amounts of data, the use of this algorithm can significantly reduce the workload of calculation, and ultimately ensure the compaction effect of the rolling equipment, thereby ensuring the smooth progress of the bridge deck maintenance construction work.

[0134] w1 is the correction factor corresponding to the preset average rolling speed, w2 is the correction factor corresponding to the preset average rolling vibration frequency, and w3 is the correction factor corresponding to the preset inclined rolling control angle.

[0135] In this example embodiment, the correction factor corresponding to the above-mentioned rolling average speed, the correction factor corresponding to the average frequency of rolling vibration and the correction factor corresponding to the oblique rolling control angle can be obtained by statistical analysis based on historical data, wherein the correction factor corresponding to the average rolling speed refers to the degree of correction of the rolling speed change, and its value range is [0,1]; the correction factor corresponding to the average frequency of rolling vibration refers to the degree of correction of the rolling vibration frequency change, and its value is defined as 0.58; the correction factor corresponding to the oblique rolling control angle refers to the degree of correction of the change of the oblique rolling control angle, and its value is specified as 0.25.

[0136] NV g It is the average rolling speed of the rolling equipment during the set material compaction cycle for the gth time, indicating the average rolling speed of the rolling equipment during the material compaction cycle.

[0137] ΔNV is the rolling speed adaptation value, which represents the ideal value when analyzing the average rolling speed. In this example embodiment, the specific value is 1.5 km / h.

[0138] NP g It is the average rolling vibration frequency of the rolling equipment during the g-th rolling in the set material compaction cycle, indicating the average rolling vibration frequency of the rolling equipment during the material compaction cycle.

[0139] ΔNP is the rolling vibration adaptation frequency, which represents the appropriate value when analyzing the average frequency of rolling vibration.

[0140] NJ is the corresponding oblique rolling control angle of the rolling equipment within the set material compaction cycle, which represents the total value of the oblique rolling control angle of the rolling equipment within the material compaction cycle.

[0141] ΔNJ is a reference value of the oblique rolling control angle, which represents an appropriate value when analyzing the oblique rolling control angle. In this example embodiment, the specific value is 45 degrees.

[0142] g is the number of each rolling, g = 1, 2, 3, ..., z, z is the number of rolling.

[0143] Specifically, the feedback management of the construction compliance status of the bridge deck maintenance is carried out, and the specific feedback management process is as follows:

[0144] The mixing management evaluation index corresponding to the asphalt mixture for bridge deck maintenance, the transportation management evaluation index corresponding to the asphalt mixture for bridge deck maintenance, the paving management evaluation index corresponding to the asphalt mixture for bridge deck maintenance and the compaction management evaluation index corresponding to the asphalt mixture for bridge deck maintenance are analyzed, and the material construction compliance of the bridge deck maintenance is obtained through comprehensive processing.

[0145] In this embodiment, the compliance of the material construction for maintaining the bridge deck can be analyzed through a compliance evaluation model to obtain data on the compliance of the bridge deck material construction.

[0146] The material construction compliance of the bridge maintenance deck is compared with the set material construction compliance threshold. If the material construction compliance of the bridge maintenance deck is lower than or equal to the set material construction compliance threshold, feedback management is performed on the construction compliance status of the bridge maintenance deck.

[0147] It needs to be explained that the above-mentioned material construction compliance thresholds are some reasonable construction thresholds summarized from past construction experience and practice, and are used as a reference to determine the material construction compliance thresholds, which represent the minimum value of material construction compliance.

[0148] In this example embodiment, if the material construction compliance value of the bridge deck maintenance is 5, and the material construction compliance threshold is set to 5, it means that the material construction compliance of the bridge deck maintenance is equal to the set material construction compliance threshold, and feedback management of the construction compliance status of the bridge deck maintenance is required; if the material construction compliance value of the bridge deck maintenance is 7, it means that the material construction compliance of the bridge deck maintenance is higher than the set material construction compliance threshold, and there is no need to perform feedback management of the construction compliance status of the bridge deck maintenance.

[0149] The specific process of feedback management on the construction compliance status of bridge deck maintenance is as follows:

[0150] First, determine the compliance standards and requirements for bridge deck maintenance construction and develop evaluation indicators; conduct real-time monitoring and testing during the bridge deck maintenance construction process, use modern technologies such as sensors and monitoring equipment to collect real-time data, check whether the construction process and quality meet the requirements of the specifications, analyze and evaluate the real-time monitoring data and quality inspection results, and evaluate the compliance status of the construction; compare the actual situation with the standard requirements to determine whether the compliance standards are met; feedback the evaluation results to the relevant responsible persons, formulate rectification measures for non-compliant areas, and track the progress of rectification.

[0151] In a specific embodiment, the present invention analyzes the material construction status of the bridge deck maintenance from multiple dimensions and evaluates the material construction compliance of the bridge deck maintenance, so as to understand the construction process of the maintenance materials in detail, provide accurate data basis for the subsequent feedback management of the construction compliance status of the bridge deck maintenance, so as to improve the management of bridge deck maintenance, ultimately enhance the bearing capacity of the bridge deck, and save funds for later maintenance and repair and reinforcement.

[0152] In this embodiment, the detailed operation of this method is to chisel away the bridge deck that needs maintenance, then perform milling construction on the bridge deck, and finally use high-viscosity modified asphalt mixture for paving, rolling and molding, so as to achieve the maintenance operation of the bridge deck.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the invention or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.
