Technical Field

Background Art

[0002] The carbon emission problem in the field of highway construction is becoming increasingly serious. Due to the wide scope of projects and the diversity of engineering types, there are many sources of carbon emissions and they are difficult to sort out. Differences in carbon emissions from materials, energy, processes and structures, coupled with the spatial heterogeneity of construction activities, make carbon emission statistics particularly complex, and the accuracy of carbon emission assessments in key construction processes is insufficient. In order to promote equipment upgrades, clean energy applications, industry decarbonization and green procurement, it is urgent to innovate carbon emission calculation technologies for highway construction to find out the bottom line of carbon emissions. Existing research is often limited to a single link or macro perspective, ignoring the time and space span, with blurred boundaries and different granularity, making it difficult to identify emission hotspots, which limits the scientific guidance of engineering emission reduction.

[0003] The traditional life cycle assessment (LCA) method is difficult to finely identify the carbon emission hotspots and mechanisms of different structures and processes in the assessment of carbon emissions in highway construction due to differences in algorithms, coefficients and data, which increases the complexity and limitations of the assessment. Therefore, it is urgent to develop a multi-scale and unified granularity highway construction carbon emission calculation and assessment system to comprehensively calculate the construction, transportation and material energy emissions of the project, support the comparison and selection of engineering schemes and the optimization of structural components, identify sensitive factors, stabilize low-carbon schemes, improve the green and low-carbon level of highway construction, and enhance the accuracy and practicality of the assessment.

Specifically, the boundary between the environment and the construction project mainly focuses on the carbon emission sources of the highway construction, including direct and indirect carbon emissions from material consumption and energy used by machinery and tools, which are divided into material carbon emissions and energy carbon emissions; the boundary between construction projects, in order to avoid repeated calculations in the analysis of multiple construction processes, clarifies the calculation scope of building materials, machinery, and equipment within the rights and responsibilities of the highway construction unit, excludes temporary borrowed items, and focuses on the relationship between highway construction activities, construction organization, material supply and carbon emissions, without considering the impact of personnel flow and life and work; the process boundary within the construction project does not consider the production and depreciation of machinery and tools, and focuses on the upstream production of raw materials, off-site processing, on-site construction and transportation carbon emissions, including carbon emission reduction from waste treatment. Through the above boundary definition, it is ensured that the activities and highway construction elements with consistent rights and responsibilities are included in the calculation scope, thereby dividing the construction process and ensuring that each construction process of the highway construction activity is operational.

[0047]

[0048] Where K represents the number of construction processes in the construction project.

[0049] Step S5, calculating the carbon emissions of highway construction according to the established source-point-volume calculation model, and mining the association relationship of carbon emissions through the FP-growth algorithm to identify the key construction processes of highway construction carbon emissions, specifically including the following sub-steps:

[0050] Step S5.1, calculate the carbon emissions of highway construction according to the established source-point-volume calculation model, and determine the construction project with the highest carbon emissions and energy consumption;

[0051] Step S5.2, each construction process and its frequency in the construction project with the highest carbon emission and energy consumption are combined into a first data pair, input into the FP-growth algorithm, and set the minimum support threshold of the FP-growth algorithm, and output the frequent construction process set;

[0052] Step S5.3: Each frequent construction process, the material consumption and energy usage of the frequent construction process, and the carbon emission energy consumption of the frequent construction process are combined into a second data pair, which is input into the FP-growth algorithm to identify the key construction processes of carbon emissions in highway construction. This method uses the FP-growth algorithm to jointly analyze the frequency of construction processes and carbon emissions to efficiently identify the key construction processes of carbon emissions in the process of highway construction projects.

[0053] The multi-scale highway construction carbon emission key construction process identification method of the present invention breaks through the limitations of traditional road construction carbon reduction algorithms, avoids the technical optimization trap of "partial links, single elements, and one-sided methods", and analyzes and mines the correlation between frequent processes, materials, energy and equipment and carbon emissions based on the identified key construction processes of carbon emissions, thereby specifying targeted emission reduction strategies, achieving deep carbon reduction, and helping the industry achieve low-carbon transformation.

[0054] For a certain highway construction, the source-point-volume calculation model of highway construction carbon emissions constructed by the present invention calculated that the total carbon emissions of the bridge project were as high as 508,800 tons, which was the construction project with the highest total carbon emissions in the highway construction. The FP-growth algorithm was used to identify key construction processes. According to the construction procedures in the bridge project and the frequency of use of each construction procedure, the first data pair is obtained, including: {[steel structure welding, 120], [rebar production and installation, 122], [concrete pouring, 115], [formwork production and installation, 105], [arch helmet installation, 96], [earth excavation, 88], [earth backfilling, 76], [component transportation, 72]}. The above first data pair is input into the FP-growth algorithm, and the minimum support threshold is set to 50. The frequent procedures mined are steel structure welding, rebar production and installation, concrete pouring, and formwork production and installation. The second data pair is composed of frequent construction procedures, material consumption and energy usage of frequent construction procedures, and carbon emission energy consumption of frequent construction procedures, and is input into the FP-growth algorithm to associate their material energy consumption and carbon emissions. The mined results are cement, sand and gravel, water, and concrete mixer trucks. Based on this, the key construction procedure is identified as concrete pouring. In order to reduce the carbon emissions of the highway construction, the concrete pouring construction process can be optimized, and measures such as low-carbon cement, recycled sand and gravel, and electric mixer trucks can be adopted. At the same time, the construction party should reasonably arrange material procurement and energy use according to the energy consumption correlation of the process, reduce waste, and thus reduce overall carbon emissions.
