[0046] As the concept of low-carbon and environmental protection is integrated into the construction process of integrated pipe corridors, more and more low-carbon measures are being applied to underground projects to reduce carbon emissions, such as: using low-carbon or even "zero-carbon" building materials to reduce carbon emissions from the source; using new force-bearing structures to reduce the consumption of high-carbon emission materials. New construction technology has low test costs, fast results, and a wide range of applications. Compared with the use of low-carbon materials or new force-bearing structures to reduce carbon emissions, the use of new pipe corridor construction technology is more likely to be favored by construction units.

[0047] However, after the construction measures are improved, if the original carbon emission calculation method in the field of housing construction is still used, it is easy to cause errors in the calculation results. The inventors found that there are many details differences between the new pipe gallery lining construction technology and the traditional housing construction technology: First, the turnover materials need to consider the number of amortization times, which is different from the carbon emission calculation of one-time materials. The existing calculation method ignores this detail; lightweight turnover materials such as templates and foam boards are large in volume, and the transportation quality is low when the vehicle is fully loaded. If the existing calculation method is considered, it is impossible to accurately quantify the carbon emissions in the off-site transportation stage; finally, the integrated pipe gallery is operated in a standard section length, and materials such as steel bars, concrete, and cement need to be transported in batches. At the same time, the transportation distance and transportation volume are different each time, but the existing calculation method does not reflect this part of the impact.

[0048] In view of this, the present application provides a carbon emission calculation method and system based on the new tunnel lining construction technology. The new tunnel lining construction technology uses a portable lining trolley as the main support, and the main support is connected to the template unit. The template is a combination of a steel template and a PP plastic template. The carbon emission calculation method based on the new tunnel lining construction technology not only considers the type and quantity of materials, but also comprehensively considers factors such as the material mass volume ratio and the standard section length of the tunnel, so as to accurately and comprehensively quantify the carbon emissions of the tunnel lining construction technology, and provide direction for the low-carbon development of modern construction technology.

[0053] This embodiment provides a carbon emission calculation method based on a new pipe gallery lining construction technology. The new pipe gallery lining construction technology uses a portable lining trolley as the main support, and the main support is connected to a template unit. The template is a combination of a steel template and a PP plastic template; Figure 1 As shown, the method includes:

[0054] Step S1: Analyze the upstream substances and energy flows of materials and energy, and establish a carbon emission factor database.

[0059] Step S6: Material carbon emission CL , Construction technology Off-site transportation carbon emissions CYS , Construction technology On-site transportation carbon emissions CNS , Construction Technology Energy Carbon Emissions NY The total carbon emissions of the new pipeline corridor lining construction technology are obtained by summing them up.

[0060] In order to facilitate the understanding of the method proposed in this application, the application scenario of the method is first introduced, namely the new pipeline corridor lining construction technology and supporting equipment.

[0061] In the above-mentioned embodiment, the portable trolley is a device specially used for transporting and installing the template, and has the functions of self-lifting and tilting.

[0062] Using a portable lining trolley as the main support can realize the automatic installation, disassembly and movement of the template, which is conducive to integrated and continuous construction, reducing the frequency and quantity of material transportation at the construction site, improving construction efficiency and reducing energy consumption. At the same time, through the precise assembly and disassembly of the template by the portable lining trolley, it can effectively reduce the loss and damage of the template, reduce material consumption, increase the turnover frequency of the template and the use efficiency of turnover materials, and reduce carbon emissions in the production process.

[0063] In this embodiment, the main support is connected to the template unit, and the length of the template unit exceeds the preset length threshold. After the pouring is completed, the formwork (a combination of the template unit and other temporary support structures) can move as a whole with the trolley, ensuring the quality of concrete pouring and maintenance while greatly improving construction efficiency.

[0064] Furthermore, the formwork is a combination of a steel formwork and a PP plastic formwork.

[0065] Among them, steel formwork is a highly durable material with a long service life and can be reused in multiple construction processes. PP plastic formwork is light in weight and easy to transport and carry, which reduces energy consumption during transportation and reduces carbon emissions in the transportation process. At the same time, PP plastic formwork is relatively durable and can be used multiple times, reducing material consumption and carbon emissions in production. In addition, by using a combination system of steel formwork and PP plastic formwork, combining the high strength of steel formwork and the lightness of PP plastic formwork, it is possible to reduce material consumption while ensuring construction quality, especially in the use of turnover materials, which can increase the reuse rate of formwork and further reduce carbon emissions. Such a low-carbon formwork design further highlights the deviation of traditional carbon emission calculation methods.

[0066] In some embodiments, the main frame is made of double-jointed channel steels welded together, and the double-jointed channel steels are connected by bolts to assemble into a portable lining trolley, and reinforcement measures are taken at the corresponding template positions;

[0067] The portable lining trolley is equipped with a trolley lifting system and a trolley power system. Correspondingly, its disassembly, assembly and movement process is as follows:

[0068] The operating personnel dismantled some reinforcement measures, and the outer primary and secondary ribs of the side wall formwork were lifted by the trolley lifting system, while the inner primary and secondary ribs relied on the main support, and cooperated with the trolley power system to move the formwork as a whole. After moving to the layout marking point, the side wall formwork was reassembled.

[0069] In this embodiment, the main support is made of double-jointed channel steels, which are welded together by two channel steels to form a strong structural support.

[0070] The double-jointed channel steels are connected by bolts. The bolt connection design facilitates disassembly and reassembly when necessary, while ensuring the reliability of the connection.

[0071] By welding and bolting the double-jointed channel steels, a complete and convenient lining trolley frame is assembled. The overall structure of the trolley has good stability and load-bearing capacity and is suitable for use in the lining construction process.

[0072] The connection between the trolley and the formwork needs to be reinforced to ensure that the formwork does not move or deform during construction. This can be achieved by adding connection points, adding support rods, using transverse reinforcements, etc. For example, steel strands and reinforcement frames can be used for fixing and reinforcement to ensure the stability of the trolley during construction.

[0073] In some embodiments, the template is a template that is processed to a certain size according to the actual situation on site;

[0074] Bolts are used to connect the steel formworks and the steel formworks to the PP plastic formworks, and plastic pins are used to connect the PP plastic formworks.

[0075] The template is processed to the required size according to the actual size requirements of the site. Before processing, the dimensions of the construction site should be measured first, especially the specific dimensions of the walls, tunnels and other structures, to ensure that the template is made to fully match the site conditions. When processing to the required size, possible errors during the construction process are also taken into account, so the processing size of the template should leave a slight margin for adjustment.

[0076] The steel formworks are connected with bolts to ensure the stability and strength of the formworks during the construction process.

[0077] Bolts are also used to connect the steel formwork and the PP plastic formwork. Due to the material difference between the steel formwork and the PP plastic formwork, the connection design should ensure that the strength of the bolt holes and the connection parts is sufficient to withstand the load during construction. For the bolt holes, you can choose reinforced plastic formwork or set steel bushings on the formwork to prevent the bolts from causing excessive pressure or damage to the plastic formwork.

[0078] In some embodiments, the novel tunnel lining construction technology further includes: arranging the positions of attached vibrators according to the standard section length of the tunnel lining.

[0079] Through the above structure, the new tunnel lining construction technology can realize the integral one-time casting scheme of the tunnel side wall without through-rods, which minimizes the use of circulating materials, ensures the strength and stability of the formwork, and saves construction costs.

[0080] The new tunnel lining construction technology includes five construction steps: side wall reinforcement binding, wall formwork installation, convenient lining trolley assembly, concrete pouring and vibration, and side wall formwork removal and reassembly.

[0081] First, the new pipe gallery lining construction technology adopts the "steel formwork + PP plastic formwork" combination system. According to the actual situation on site, the template size is fixed and processed. Bolts are used between steel formworks and between steel formworks and PP plastic formworks, and plastic pins are used to connect PP plastic formworks to achieve a quick assembly effect. Secondly, the main support is made by welding double-jointed channel steel, and the positions of multiple main supports are accurately located in conjunction with lifting equipment. Bolts are used to connect each other to complete the assembly of the convenient lining trolley, and reinforcement measures are taken at the corresponding template positions. Then, according to the standard section length of the pipe gallery lining, the position of the attached vibrator is reasonably arranged to ensure that its range of action covers the entire concrete pouring area. Finally, the operator dismantles some reinforcement measures, and the outer primary and secondary ribs of the side wall template are lifted by the convenient lining trolley lifting system, while the inner primary and secondary ribs rely on the main support, and cooperate with the trolley power system to realize the overall movement of the formwork. After moving to the marking point for laying out the line, the side wall template is reassembled.

[0082] In some embodiments, analyzing the upstream material and energy flows of materials and energy and establishing a carbon emission factor database includes:

[0083] Step S11: sort out the types of materials and energy used in the new pipe gallery lining construction technology, and clarify the life cycle stages of each type of material and energy;

[0084] Step S12: Calculate the carbon emissions of each type of material and energy at each life cycle stage and sum them up. Multiply the summed results by the material and energy heterogeneity coefficients to obtain the corresponding material carbon emission factor per unit mass. and energy carbon emission factors , and establish a carbon emission factor database for new pipeline corridor lining construction technology based on the calculation results.

[0085] In this embodiment, sorting out the types of materials and energy used in the new tunnel lining construction technology and understanding its production process will help to more accurately estimate the carbon emissions of each material and energy during use, thereby improving the accuracy of the emission factor.

[0086] Among them, the carbon emission factors of different types of materials per unit mass are and energy carbon emission factors The calculation formula is as follows:

[0087] (1)

[0089] Where: YCJ Represents the carbon emissions generated during the mining stage of raw materials in this type of material; YCY Indicates the carbon emissions generated during the transportation of raw materials in this category of materials; YCS Indicates the carbon emissions generated during the raw material processing stage of this type of material; , is the coefficient of non-uniformity; M Indicates the total amount of this type of material; RLS Indicates the carbon emissions released by direct combustion of this type of energy; JXS Represents the carbon emissions generated during the production phase of equipment powered by this type of energy; JXW Represents the carbon emissions generated during the maintenance phase of equipment powered by this type of energy; N Indicates the total amount of this type of energy.

[0090] The carbon emission factors of materials per unit mass are calculated by the above formula. and energy carbon emission factors , statistical results and establish a dynamic database of carbon emission factors, which can be adjusted in real time according to market conditions to meet timeliness requirements.

[0091] In some embodiments, the main materials and turnover materials in the construction of new pipe gallery linings are identified, the turnover frequency is considered and the consumption of each type of material is refined to calculate the carbon emissions of construction technology materials. CL ,include:

[0092] Step S21: Divide the materials used on site into main materials and turnover materials;

[0093] Step S22: Counting the amortization times of different turnover materials, and calculating the actual usage of each type of turnover material according to the amortization times;

[0094] Step S23: Calculate the product of the theoretical usage of each type of main material and the carbon emission factor of the main material to obtain the material carbon emission of each type of main material;

[0095] Step S24: Calculate the product of the actual usage of each type of turnover material and the carbon emission factor of the turnover material, and then divide it by the amortization times corresponding to the turnover material to obtain the material carbon emission of the turnover material;

[0096] Step S25: Add up the material carbon emissions of all types of main materials and all types of turnover materials to obtain the material carbon emissions CL .

[0097] Specifically, first, identify the types of materials used on site in combination with the material contract, which are mainly divided into main materials and turnover materials. The main materials include steel bars, concrete, cement, sand, etc., and the turnover materials include steel formwork, PP plastic formwork, wooden formwork, wooden support, etc. Secondly, count the number of amortization times of different turnover materials , taking it into account in the material carbon emission calculation model, further refining the actual use of turnover materials; finally, the carbon emission of construction technology materials is calculated according to the following expression CL :

[0099] Where: Indicates a Theoretical usage of main materials; Indicates a Carbon emission factor of main materials; Indicates g Theoretical usage of turnover materials; Indicates g Carbon emission factors of turnover materials; Indicates the number of amortization times corresponding to turnover materials.

[0100] In some embodiments, step S3: determine the category of lightweight turnover materials, consider the full load mass and full load volume of the transport vehicle, optimize the off-site transportation model, and calculate the off-site transportation carbon emissions of the construction technology. CYS ,include:

[0101] Step S31: further classify the turnover materials into heavy materials and light materials, and determine the actual usage of each type of heavy materials and light materials;

[0102] Step S32: Obtain the full load mass and full load volume values ​​of various types of transport vehicles, and calculate the total off-site transportation volume of various types of lightweight materials in combination with the density of the lightweight materials;

[0103] Step S33: Calculate the off-site transportation carbon emissions of construction technology according to the following formula CYS :

[0104] (4)

[0105] In the formula, , Respectively represent b Lightweight materials, d Actual usage of heavy-duty materials (theoretical turnover); Indicates the transport b Lightweight materials used c The fully loaded mass value of the vehicle; Indicates the transport d Type 1 for heavy materials e The fully loaded mass value of the vehicle; , Respectively represent b Lightweight materials, d The distance that heavy materials are transported from the market to the construction site; , Respectively represent c Category e Energy usage per 100 kilometers at full load mass of similar vehicles; Indicates c The fully loaded volume value of the vehicle; Indicates b Density of similar lightweight materials; , Indicates c Category e The density of energy used by the vehicle; , Indicates c Category e Carbon emission factor of the energy used by this type of vehicle.

[0106] Specifically, in step S31, the use of heavy materials and lightweight materials in the turnover materials is determined in combination with the design drawings, where heavy materials refer to construction materials with small volume and high density, such as steel formwork, tension screws, etc.; lightweight materials refer to construction materials with large volume and low density, such as PP plastic formwork, wooden formwork, etc. In step S32, the full load mass and full load volume values ​​of the lightweight turnover material transportation vehicle are collected, and the ratio of the product of the full load volume and material density to the full load mass is used to obtain the correction coefficient, which is taken into account in the off-site transportation carbon emission calculation model of construction technology, and the total off-site transportation volume is further refined in combination with the material density; finally, in step S33, the off-site transportation carbon emission of construction technology is calculated using formula (4): CYS .

[0107] In some embodiments, step S4: considering the working efficiency of the engine of the on-site transport vehicle and combining the standard section length of the pipeline corridor, optimizing the on-site transport model, and calculating the on-site transport carbon emissions of the construction technology CNS ,include:

[0108] Step S41: Determine the energy correction coefficients of various vehicles under low engine efficiency ;

[0109] Step S42: Based on the standard length of the corridord , determine the total one-way distance of on-site transportation S ;

[0110] Step S43: Based on the energy correction factor , Total one-way distance of on-site transportation S , the energy usage per kilometer of various vehicles in normal and empty states, and the carbon emission factors of the energy used by various vehicles, calculate the on-site transportation carbon emissions of various vehicles one by one, and sum them up to obtain the on-site transportation carbon emissions of construction technology CNS .

[0111] Specifically, first, the energy consumption per kilometer of the vehicle is obtained based on the information provided by the manufacturer and the actual application effect on site, and then the energy consumption per kilometer is calculated based on the theoretical value. f Energy correction factor for vehicles with low engine efficiency ; Secondly, based on the standard length of the corridor d , using the Gaussian algorithm, determine the total one-way distance of transportation within the field S ; Finally, the following formula is used to calculate the carbon emissions of transportation within the construction technology site CNS :

[0114] The standard length of the corridor is determined based on the construction design and actual site conditions, reflecting the actual workload and transportation distance in the corridor construction. d , using the Gaussian algorithm, determine the total one-way distance of transportation within the field S , which can more accurately reflect the actual transportation needs and construction conditions of each construction stage, so that the total transportation distance can accurately reflect the transportation mileage required in the actual construction, and thus provide a basis for calculating the carbon emissions generated during the transportation process. In other words, considering the standard section length can help to more reasonably design the transportation route in the construction area, avoid underestimating the transportation distance, and ensure that the actual transportation carbon emissions are calculated. The standard section length can be used as a benchmark to clarify the transportation distance of different construction stages, thereby providing more accurate data support for the calculation of carbon emissions.

[0115] Among them, the Gaussian algorithm is a method for calculating the shortest path and optimizing the transportation route. It finds the most effective path by iteratively calculating multiple possible paths to the target point. The specific implementation steps of the algorithm can be performed with reference to the existing technology and will not be repeated here.
