[0046] The historical construction data includes historical construction geology, historical construction steps, historical equipment models, historical equipment quantities and historical construction durations;

[0047] The historical construction geology represents the geology of the region corresponding to the historical construction road, including structure, topography and hydrogeology, the historical construction steps include clearing and dredging, drainage and pipeline and roadbed filling and corresponding step parameters, the historical equipment models represent the construction equipment models corresponding to each historical construction step, which are obtained through an equipment database, the historical equipment quantities represent the equipment quantities of each historical equipment model of each historical construction step, and the historical construction durations represent the historical construction durations corresponding to each historical construction step.

[0048] The structure includes faults, folds and active fault zones, the topography includes mountainous areas, hilly areas, valleys, alluvial-proluvial plains, karst tablelands and coastal terraces, and the hydrogeology includes groundwater level depth, aquifer type and recharge-discharge relationship, and the aquifer type includes phreatic water and confined water.

[0050] The step parameters corresponding to the drainage and pipeline include ditch bottom longitudinal slope, open ditch bottom width, catchment well spacing, water pump flow, groundwater drawdown, minimum drainage slope, drainage pipeline roughness, drainage well spacing, backfill compactness and drainage pipe diameter;

[0051] The step parameters corresponding to the roadbed filling include layer thickness, rolling speed, rolling passes and filler particle size.

[0052] Obtaining the geological combination by arranging and combining the geological types in the geology, obtaining any geological combination, comparing the geological combination with the historical construction geology, when the geological combination is the same as the historical construction geology, retaining the geological combination, when the geological combination is not the same as the historical construction geology, jumping to the next historical construction geology, when there is a geological combination that is the same as the historical construction geology, retaining the geological combination, when all the historical construction geologies are traversed and there is no geological combination that is the same as the historical construction geology, deleting the geological combination;

[0053] Traversing each retained geological combination to obtain each first screening combination.

[0054] In a specific implementation, by arranging and combining geological elements (faults, folds, landforms, hydrogeology), and comparing with historical construction geology records, about 80% of invalid combinations can be eliminated. Theoretically, if all "faults x folds x active fault zones x 6 types of landforms x 3 types of hydrogeology x 2 types of aquifers" are arranged and combined, the total number of combinations is approximately 2160. In actual engineering, after comparing with 110,000 historical construction geology records and eliminating invalid combinations, only 312 valid combinations are left, the sample space compression rate is approximately 85.6%, the total amount of geological-technological-equipment ternary is reduced from 4.8 million to 680,000, the time consumption of a single query of the graph database is reduced from 2.1s to 0.18s, which meets the <500ms latency requirement of real-time scheduling on site, and the 312 retained "first screening combinations" have been upgraded to reusable templates. In subsequent new projects with the same geology, corresponding templates can be directly called to reduce the pre-survey-scheme design time by 15-20 working days on average.

[0055] Selecting any first screening combination, performing first screening on historical construction steps, historical equipment models, historical equipment quantities, and historical construction time lengths to obtain first data, and the screening method of the first data includes:

[0056] Obtaining any historical construction data, comparing the historical construction geology of the historical construction data with the first screening combination, when the historical construction geology is the same as the first screening combination, setting the corresponding historical construction steps, historical equipment models, historical equipment quantities, and historical construction time lengths as the first data, when the historical construction geology is not the same as the first screening combination, jumping to the next historical construction data;

[0057] Traversing each first screening combination to obtain each first data.

[0058] In a specific implementation, through two-level filtering of "geological combination → step / equipment / duration", 60%-80% of the noise samples in the original hundreds of thousands of historical records can be removed at one time. Taking the Sichuan Xinhe Expressway tunnel section as an example, after geological combination matching, only 2847 out of the original 11233 drilling-construction records are retained (compression ratio ≈ 75%), the GPU training time is reduced from 6.4 h to 1.5 h, the convergence speed is increased by 4.3 times, and the "first data" obtained through double screening naturally meets the current road section geological boundary conditions, and the scheduling system does not need to make cross-geological extrapolation. After mapping 17 groups of feasible schemes to the real-time geological model, the field measurement and prediction deviation of Chenglan Railway is less than 3%, realizing "one-key issuance".

[0059] According to the first screening combination and the first data, a road construction knowledge spectrum is constructed, and a construction method of the road construction knowledge spectrum comprises:

[0060] When the first data is a historical construction step or a historical equipment model, the number of occurrences of the first data is counted, denoted as a first number, and the total number of the first data is counted, denoted as a second number, a first ratio of the first number to the second number is calculated, a first value is set as a first value threshold, and the first ratio is compared with the first value. When the first ratio is greater than or equal to the first value, the corresponding historical construction step or historical equipment model is retained, and when the first ratio is less than the first value, the corresponding historical construction step or historical equipment model is deleted.

[0061] When the data is a historical equipment quantity or a historical construction duration, any first screening combination and its corresponding first data are obtained, a first average value of each type of the first data is calculated, and the first average value is set as a construction parameter of the first screening combination.

[0062] The construction parameters of each first screening combination are traversed, a first mapping relationship of the first screening combination, the retained historical construction step, the retained historical equipment model, and the construction parameter is constructed, and the first mapping relationship is set as the road construction knowledge spectrum.

[0063] In a specific implementation, relying on the digital platform of the 68 km tunnel group of Sichuan Xinhe Expressway, after two screenings, only 312 valid combinations were left from the original 2160 geological combinations; After filtering by the threshold of "first number / second number >= 0.15", the construction step nodes were compressed from 312*3=936 to 197, the equipment model nodes were compressed from 312*8=2496 to 421, the total number of atlas nodes decreased by 83%, the Neo4j graph database query time decreased from 2.1s to 0.13s, meeting the <500ms real-time scheduling requirements on site. In the 2023Q3 adjustment section verification of the Yuelongmen Tunnel of Chenglan Railway, the "three-step seven-step excavation method" and "wet spraying robot + three-arm drill rig" combination left by the "first ratio >= 0.15" had an actual frequency of 92% on site, and the prediction accuracy improved by 19%; the eliminated low-frequency combination had an on-site occurrence rate of only 3%, and the false positive rate decreased by 81%. For the remaining 312 first-screening combinations, the first average of the historical equipment quantity and the construction duration was calculated as the node attribute. When reused in the 1.8 km test section of the Liuzhou Lianhua Tunnel, the monthly footage prediction RMSE decreased from 1.82d to 0.47d, and the R² improved from 0.79 to 0.94. The knowledge graph constructed by the "frequency threshold + averaging" two-step method not only compressed the node scale by more than 80%, but also achieved an error of <0.5d in construction duration prediction and an on-site accuracy of >90%, and brought comprehensive benefits such as hundreds of thousands of yuan in cost savings and dozens of tons in carbon emission reduction for a single project.

[0064] Obtain the current road section number, before obtaining the current road section number, preset the road section number of the current road, the road section number is a natural number, the setting method of the road section number includes:

[0065] Set the first distance as the segmentation distance, the road surface of the current road is filled as a rectangle, the length of the current road is segmented according to the first distance, the current road is segmented into N sub-rectangles with the line segment parallel to the width of the current road as the segmentation line, from any direction, the sub-rectangles are numbered in the order of their appearance;

[0066] After numbering, during the construction process of the current road section, the current relevant data is input into the dispatching system by the construction supervisor according to the construction progress, the current relevant data includes the current construction road section number, the current equipment model used, the corresponding current number of equipment used, the current construction step and the current construction duration;

[0067] Call the dispatching system, input the current road section number into the dispatching system, and obtain the current relevant data corresponding to the current road section number.

[0068] The method for obtaining the first dispatching data according to the current relevant data and the road construction knowledge graph includes:

[0069] Obtain a road construction knowledge graph, input the current construction geology into the road construction knowledge graph, obtain the retained historical construction steps, the retained historical equipment models and the construction parameters, compare the current construction steps with the retained historical construction steps, jump to the corresponding retained historical equipment models and construction parameters, compare the current equipment model in use with the retained historical equipment models;

[0070] When the current equipment model in use is different from the retained historical equipment models, obtain the construction parameters of the retained historical equipment models that are different from the current equipment model in use, and call the equipment of the retained historical equipment models that have the same number of devices as the construction parameters;

[0071] When the current equipment model in use is the same as the retained historical equipment models, obtain the construction parameters of the retained historical equipment models that are the same as the current equipment model in use, compare the current number of equipment in use with the construction parameters, and when the current number of equipment in use is less than or equal to the corresponding construction parameters, calculate the difference between the number of devices in the construction parameters and the current number of equipment in use, and call the equipment of the corresponding equipment models that have the same number of devices as the difference between the number of devices in the construction parameters and the current number of equipment in use.

[0072] In specific implementation, the road section number is generated once and globally reused, completely eliminating manual segmentation errors, making the three codes of “kilometer pile-GIS coordinates-scheduling instructions” into one, and any subsequent algorithm call can achieve zero conversion overhead. Sub-rectangular regular segmentation reduces two-dimensional roads to linear natural number sequences, and the retrieval complexity is reduced from O(LxW) to O(N). The scheduling query delay decreases exponentially, and the current related data is written with the road section number as the unique primary key, naturally satisfying “write indexing”, avoiding secondary table building, saving storage and computing resources, and the knowledge graph is searched according to the four-level chain of “current construction geology-step-equipment-number”, the hit path is unique, and scheduling conflicts caused by multi-path fuzzy matching are eliminated.

[0073] The method for compensating the first scheduling data according to the meteorological data comprises:

[0074] Obtain the current construction duration, obtain the expected duration of the corresponding construction step, calculate the second ratio of the construction duration and the expected duration, calculate the difference between the expected construction duration and the current construction duration, call the meteorological data within the duration from the current time point to the difference between the expected construction duration and the current construction duration, count the duration of extreme weather in the meteorological data, calculate the third ratio of the duration of extreme weather and the duration from the current time point to the difference between the expected construction duration and the current construction duration, and calculate the fourth ratio of the number of devices in the first scheduling and the third ratio. Set the fourth ratio to update the number of devices in the first scheduling.

[0075] In a specific implementation, by the third ratio of "extreme weather duration / remaining operation duration", the weather risk is converted from a qualitative description to a continuous variable that can be directly involved in the calculation, realizing the numerical expression of meteorological influence, the third ratio linearly compensates the number of devices, so that the resource investment and meteorological risk are automatically matched: high risk→more equipment to compress the construction period, low risk→reduce equipment to avoid waste, the overall resource allocation is real-time elastic scaling with the weather, the fourth ratio directly maps the meteorological disturbance to the number of devices, re-establishes the "weather-construction period-resource" three-dimensional coupling relationship, avoids the construction period drift or resource idling caused by weather mutation in traditional fixed plan, only one ratio calculation can complete the compensation, without additional training or iteration, the calculation amount is linearly related to the length of real-time meteorological data, which can be completed on the edge in seconds to meet the on-site scheduling demand, each meteorological update will recalculate the compensation amount, forming a rolling correction mechanism, the system error decreases monotonically with time, ensuring that the construction period prediction error continuously converges in the long run.

[0076] By analyzing historical construction data, the present application constructs a road construction knowledge graph, which can structure the scattered experience, rules, cases and complex associations between entities, such as the efficiency of a certain construction technology under specific geological conditions, the failure rate of a certain type of machinery under specific weather conditions, etc., and through the introduction of real-time meteorological data such as rainfall, high temperature, strong wind, etc., the first scheduling data is compensated, breaking the limitations of traditional static plans, and dynamically adjusting the construction process, resource input and construction period arrangement according to the real-time changes of the weather, the dynamic adjustment realized by meteorological compensation can reduce the non-productive consumption caused by adverse weather, such as mechanical idling and personnel standby, through the construction of road construction knowledge graph to realize experience reuse and scientific decision-making, and through the dynamic compensation of meteorological data to respond to environmental changes, the two work together, finally realizing the intelligentization, refinement and high efficiency of construction scheduling, which has significant beneficial effects in improving engineering quality, ensuring construction safety, reducing project cost and shortening construction period, etc.
