Description

Technical Field

[0001] This invention relates to the field of building materials technology, and in particular to a method and system for preparing high-strength basalt fiber concrete for lock corridors. Background Technology

[0002] As the core water conveyance structure of a shipping hub, the concrete flow surface of the lock channel is constantly exposed to the harsh environment of high-speed sediment-laden water flow, wet-dry cycles, and freeze-thaw cycles. These factors work together to accelerate the deterioration of the structure's mechanical and durability properties, and even lead to large-scale concrete spalling, seriously threatening the safe operation and long-term durability of the lock.

[0003] Adding fibers to concrete is an effective measure to improve crack resistance. However, existing technologies often employ complex surface modification processes to enhance the bond between fibers and the matrix, which increases production costs and process complexity. Furthermore, current research largely focuses on crack resistance or conventional mechanical properties, lacking systematic research and optimization on impact and abrasion resistance—a key indicator for controlling the lifespan of lock channels. Therefore, there is an urgent need for a simple formulation of basalt fiber reinforced concrete for lock channels with high crack and impact and abrasion resistance, requiring no complex modification processes, and its preparation method. Summary of the Invention

[0004] This invention provides a method and system for preparing high-strength basalt fiber concrete for lock channels, the main purpose of which is to improve the strength, durability and preparation efficiency of basalt fiber concrete for lock channels.

[0005] To achieve the above objectives, the present invention provides a method for preparing high-strength basalt fiber reinforced concrete for lock corridors, comprising:

[0006] The fiber concrete preparation instruction is confirmed upon receipt. Based on the fiber concrete preparation instruction, the fiber concrete preparation environment is confirmed. The fiber concrete preparation environment includes a fiber concrete preparation system and preparation raw materials. The fiber concrete preparation system includes a raw material pretreatment unit, a mixing unit, a molding and curing unit, and a performance testing unit. The preparation raw materials include river sand, crushed stone, and basalt fiber.

Based on the water type, cement type, suitable river sand, suitable crushed stone, and suitable basalt fiber, weigh them according to the optimal batching ratio to obtain the target water, target cement, target river sand, target crushed stone, and target basalt fiber.

[0011] The performance of the molded and cured specimen is tested by the performance testing unit to obtain compressive strength, crack strength and impact abrasion resistance. The comprehensive performance index is calculated based on the compressive strength, crack strength and impact abrasion resistance. If the comprehensive performance index is greater than or equal to the preset performance index threshold, the target concrete is determined to be high-strength concrete. Based on the high-strength concrete, the basalt fiber concrete of the raw materials is prepared.

[0021] The screened river sand is dried using the raw material pretreatment unit to obtain initially suitable river sand. The moisture content of the initially suitable river sand is then measured. If the moisture content of the river sand is greater than a preset moisture threshold, the initially suitable river sand is used as screened river sand, and the process returns to the step of drying the screened river sand using the raw material pretreatment unit. This process continues until the moisture content of the river sand is less than the preset moisture threshold, at which point the initially suitable river sand is confirmed as suitable river sand.

[0022] Optionally, obtaining the water type, cement type, and optimal batching ratio involves weighing the water type, cement type, suitable river sand, suitable crushed stone, and suitable basalt fiber according to the optimal batching ratio to obtain target water, target cement, target river sand, target crushed stone, and target basalt fiber, including:

[0029] The initial mixture is subjected to homogeneity analysis based on a pre-built image analysis unit to obtain analysis results, wherein the analysis results are homogeneous or non-homogeneous. If the analysis results are homogeneous, the initial mixture is identified as a dry mixture.

[0030] If the analysis result is non-uniform, then increase the dry mixing speed and extend the dry mixing time. Take the increased dry mixing speed and extended dry mixing time as the initial dry mixing speed and initial dry mixing time, respectively. Then return to the step of stirring the target river sand, target gravel and target basalt fiber in the mixing unit based on the initial dry mixing speed and initial dry mixing time, until the analysis result is uniform. Then the initial mixture is confirmed as a dry mixture.

[0037] The initial concrete is mixed based on the second mixing time and the mixing unit to obtain the target concrete.

[0038] Optionally, the step of preparing a concrete specimen based on the target concrete and the molding and curing unit, and then curing the concrete specimen to obtain a molded and cured specimen, includes:

[0039] Obtain the specimen dimensions, and then obtain the specimen mold based on the specimen dimensions;

[0040] The target concrete is poured into the specimen mold at a uniform speed, and the target concrete in the specimen mold is vibrated using a pre-constructed vibration device to obtain the vibrated specimen.

[0041] Based on the preset initial setting time, the pre-constructed room temperature environment, and the molding and curing unit, the vibrated specimens were left to stand to obtain concrete specimens.

[0042] Obtain the curing temperature and curing time for curing, and cure the concrete specimen based on the molding curing unit, curing temperature and curing time to obtain the molded curing specimen.

[0043] Optionally, the performance testing of the molded and cured specimen based on the performance testing unit to obtain compressive strength, crack strength, and impact and abrasion resistance includes:

[0052] To achieve the above objectives, the present invention also provides a high-strength basalt fiber reinforced concrete preparation system for lock corridors, comprising:

[0053] An environmental verification module is used to verify the receipt of a fiber-reinforced concrete preparation instruction and to verify the fiber-reinforced concrete preparation environment based on the instruction. The fiber-reinforced concrete preparation environment includes a fiber-reinforced concrete preparation system and preparation raw materials. The fiber-reinforced concrete preparation system includes a raw material pretreatment unit, a mixing unit, a molding and curing unit, and a performance testing unit. The preparation raw materials include river sand, crushed stone, and basalt fiber.

[0054] The raw material pretreatment module is used to obtain the target size and pretreat the raw materials based on the raw material pretreatment unit and the target size to obtain suitable river sand, suitable crushed stone and suitable basalt fiber;

[0055] The precise batching module is used to obtain the type of water, the type of cement, and the optimal batching ratio. Based on the type of water, the type of cement, suitable river sand, suitable crushed stone, and suitable basalt fiber, the components are weighed according to the optimal batching ratio to obtain the target water, target cement, target river sand, target crushed stone, and target basalt fiber.

[0056] The target river sand, target crushed stone and target basalt fiber are dry-mixed using the mixing unit to obtain a dry-mixed mixture. The target concrete is then wet-mixed using the mixing unit with the dry-mixed mixture, target water and target cement.

[0057] Based on the target concrete and the molding and curing unit, a specimen was prepared to obtain a concrete specimen. The concrete specimen was then cured to obtain a molding and curing specimen.

[0058] The preparation verification module is used to perform performance tests on the molded and cured specimens based on the performance testing unit to obtain compressive strength, crack strength and impact and abrasion resistance. Based on the compressive strength, crack strength and impact and abrasion resistance, a comprehensive performance index is calculated. If the comprehensive performance index is greater than or equal to a preset performance index threshold, the target concrete is determined to be high-strength concrete. Based on the high-strength concrete, the preparation of basalt fiber concrete from the raw materials is realized.

[0059] To address the above problems, the present invention also provides an electronic device, the electronic device comprising:

[0060] Memory, storing at least one instruction;

[0061] The processor executes the instructions stored in the memory to implement the above-described method for preparing high-strength basalt fiber concrete for lock channels.

[0062] To address the aforementioned problems, the present invention also provides a computer-readable storage medium storing at least one instruction, which is executed by a processor in an electronic device to implement the above-described method for preparing high-strength basalt fiber reinforced concrete for lock channels.

[0063] To address the problems described in the background art, this invention confirms the receipt of fiber-reinforced concrete preparation instructions and, based on these instructions, confirms the fiber-reinforced concrete preparation environment. This environment includes a fiber-reinforced concrete preparation system and raw materials. The preparation system comprises a raw material pretreatment unit, a mixing unit, a molding and curing unit, and a performance testing unit. The raw materials include river sand, crushed stone, and basalt fibers. Therefore, this invention considers the complex environment of high-strength requirements in basalt fiber-reinforced concrete preparation for lock corridors. By confirming the preparation environment, modular system integration is ensured, providing a reliable foundation for subsequent optimized preparation and thereby improving the overall suitability of concrete production. Adaptability and stability; obtaining target size: based on the raw material pretreatment unit and the target size, the raw materials are pretreated to obtain suitable river sand, suitable crushed stone, and suitable basalt fiber. It is evident that this invention introduces a size-targeted pretreatment mechanism to achieve fine optimization of raw materials, avoiding the particle size unevenness problem of traditional coarse processing, thereby improving fiber dispersibility and material compatibility; obtaining water type, cement type, and optimal batching ratio: based on the water type, cement type, suitable river sand, suitable crushed stone, and suitable basalt fiber, they are weighed according to the optimal batching ratio to obtain target water, target cement, target river sand, target crushed stone, and target basalt fiber. It is evident that this invention ensures precise control of element ratios through optimal batching and weighing, reducing waste. The invention optimizes the strength base, thereby improving the internal uniformity and mechanical properties of concrete. Based on the mixing unit, the target river sand, target crushed stone, and target basalt fiber are dry-mixed to obtain a dry mixture. Based on the mixing unit, the dry mixture, target water, and target cement are wet-mixed to obtain the target concrete. This embodiment of the invention employs a step-by-step dry-wet mixing mechanism to avoid fiber agglomeration and uneven moisture distribution, thereby improving mixing efficiency and concrete density. Based on the target concrete and the molding and curing unit, concrete specimens are prepared. The concrete specimens are then cured to obtain molded and cured specimens. This invention combines molding and curing to optimize crystal structure development and reduce premature aging. To mitigate the risk of cracking and ensure the representativeness and durability of the specimens, the performance testing unit performs performance tests on the molded and cured specimens to obtain compressive strength, crack strength, and impact abrasion resistance. A comprehensive performance index is calculated based on these strengths. If the comprehensive performance index is greater than or equal to a preset performance index threshold, the target concrete is identified as high-strength concrete. Based on this high-strength concrete, the preparation of basalt fiber concrete from the raw materials is achieved. It is evident that this invention calculates indices using multiple strength indicators to form a closed-loop quality verification, and the threshold judgment ensures high-strength output. Therefore, this invention can improve the strength, durability, and preparation efficiency of basalt fiber concrete for lock corridors. Attached Figure Description

[0072] Reference Figure 1 The diagram shown is a flowchart illustrating a method for preparing high-strength basalt fiber reinforced concrete for lock channels according to an embodiment of the present invention. In this embodiment, the method for preparing high-strength basalt fiber reinforced concrete for lock channels includes:

[0073] S1. Confirm receipt of fiber concrete preparation instruction, and confirm the fiber concrete preparation environment based on the fiber concrete preparation instruction. The fiber concrete preparation environment includes a fiber concrete preparation system and preparation raw materials. The fiber concrete preparation system includes a raw material pretreatment unit, a mixing unit, a molding and curing unit, and a performance testing unit. The preparation raw materials include river sand, crushed stone, and basalt fiber.

[0074] It should be explained that the "fiber-reinforced concrete preparation instruction" refers to an instruction issued by personnel intending to prepare high-strength basalt fiber-reinforced concrete for lock channels; the "fiber-reinforced concrete preparation environment" refers to the necessary environment for preparing high-strength basalt fiber-reinforced concrete for lock channels; and the "fiber-reinforced concrete preparation system" refers to a system capable of preparing high-strength basalt fiber-reinforced concrete for lock channels. This system includes a raw material pretreatment unit, a mixing unit, a molding and curing unit, and a performance testing unit. For specific application details of these units, please refer to subsequent embodiments. The "preparation raw materials" refer to the raw materials used in preparing high-strength basalt fiber-reinforced concrete for lock channels, including river sand, crushed stone, and basalt fibers. The purpose of this invention is to achieve the preparation of high-strength basalt fiber-reinforced concrete suitable for lock channels.

[0075] For example, Zhang is a worker at a building materials factory. In order to prepare high-strength basalt fiber concrete suitable for the lock corridor, Zhang issued a fiber concrete preparation instruction and confirmed the fiber concrete preparation environment.

[0076] S2. Obtain the target size, and pre-treat the raw materials based on the raw material pre-treatment unit and the target size to obtain suitable river sand, suitable crushed stone and suitable basalt fiber.

[0077] Furthermore, the step of obtaining the target size involves pre-treating the raw materials based on the raw material pre-treatment unit and the target size to obtain suitable river sand, suitable crushed stone, and suitable basalt fiber, including:

[0078] The target size is obtained based on a pre-built parameter database, wherein the target size includes the range of fineness modulus of river sand, the range of particle size distribution of crushed stone, and the range of fiber length of basalt.

[0079] The river sand is screened based on a pre-constructed screening device and a fineness modulus range of river sand, and the screened river sand is dried based on the raw material pretreatment unit to obtain suitable river sand.

[0080] The initial suitable crushed stone is obtained by using the screening device, crushed stone and crushed stone particle size distribution range, and the initial suitable crushed stone is washed based on the raw material pretreatment unit to obtain suitable crushed stone;

[0081] Based on the raw material pretreatment unit and the basalt fiber length range, the basalt fiber is length-screened to obtain suitable basalt fiber.

[0082] It should be understood that the method for obtaining the target size based on the pre-constructed parameter database refers to retrieving and extracting parameters from the parameter database that match the preparation requirements of basalt fiber concrete for lock channels. The parameter database refers to a pre-constructed database storing the size range of suitable raw materials for concrete used in lock channels. The target size refers to the range of raw material size parameters that match the preparation requirements of basalt fiber concrete for lock channels, including the range of fineness modulus of river sand, the range of particle size distribution of crushed stone, and the range of basalt fiber length. The range of fineness modulus of river sand refers to the range of fineness modulus of river sand. In this invention, the fineness modulus of river sand is 2.3 to 2.7. The range of particle size distribution of crushed stone refers to the range of particle size distribution of crushed stone. In this invention, the range of particle size distribution of crushed stone is 5 mm to 20 mm. The range of basalt fiber length refers to the range of basalt fiber length. In this invention, the range of basalt fiber length is 9 mm to 15 mm. The method for obtaining initially suitable crushed stone using the screening device, crushed stone, and crushed stone particle size distribution range is described in the subsequent steps for screening the river sand based on the pre-constructed screening device and river sand fineness modulus range, and will not be repeated here. The method for cleaning the initially suitable crushed stone using the raw material pretreatment unit refers to using the raw material pretreatment unit to clean the initially suitable crushed stone to remove dust, fine stone chips, and other irrelevant impurities from the surface of the initially suitable crushed stone, preventing impurities from forming a weak isolation layer between the crushed stone and cement paste, which would affect the performance of the concrete. The initially suitable crushed stone refers to the crushed stone after screening. The raw material pretreatment unit refers to a functional module capable of screening, drying, and cleaning different types of raw materials. Optionally, the raw material pretreatment unit can be constructed using screens of different aperture sizes, hot air dryers, drum cleaners, etc. The suitable crushed stone refers to the initially suitable crushed stone after cleaning. The method for length screening of the basalt fibers refers to the subsequent steps for screening the river sand based on the pre-constructed screening device and river sand fineness modulus range, and will not be repeated here. The suitable basalt fiber refers to basalt fiber whose length conforms to the length range of basalt fiber obtained after screening.

[0083] Furthermore, the river sand is screened based on the pre-constructed screening device and the fineness modulus range of the river sand, and the screened river sand is dried based on the raw material pretreatment unit to obtain suitable river sand, including:

[0084] The upper and lower limits of particle size are obtained based on the fineness modulus range of the river sand.

[0085] A screen set is obtained based on the screening device, wherein the screen set includes multiple screens with different aperture sizes;

[0086] Modulus matching is performed based on the upper and lower limits of particle size and the sieve set to obtain the upper limit sieve and the lower limit sieve. Preliminary screening is performed based on the upper limit sieve, and collection is performed based on the lower limit sieve to obtain screened river sand.

[0087] The screened river sand is dried using the raw material pretreatment unit to obtain initially suitable river sand. The moisture content of the initially suitable river sand is then measured. If the moisture content of the river sand is greater than a preset moisture threshold, the initially suitable river sand is used as screened river sand, and the process returns to the step of drying the screened river sand using the raw material pretreatment unit. This process continues until the moisture content of the river sand is less than the preset moisture threshold, at which point the initially suitable river sand is confirmed as suitable river sand.

[0088] It should be understood that the method for obtaining the upper and lower limits of particle size based on the fineness modulus range of river sand refers to setting the upper and lower limits of the particle size range as the upper and lower limits of the particle size, respectively, based on the fineness modulus range of river sand. For example, the fineness modulus is 3.0-2.3, and the average particle size is 0.5-0.35 mm. The method for obtaining the screen set based on the screening device refers to calling the screen set configured by the screening device, which consists of multiple screens with different standard apertures. The screen set refers to the set used for... The method of matching the upper and lower limits of particle size with the set of screens is to compare the upper and lower limits of particle size with the nominal aperture of each screen in the set of screens one by one, and select the screens with aperture sizes equal to or slightly smaller than the upper limit of particle size as the upper limit screens, and select the screens with aperture sizes equal to or slightly larger than the lower limit of particle size as the lower limit screens. The upper limit screens and lower limit screens refer to the screens with corresponding aperture sizes obtained by matching from the set of screens based on the upper and lower limits of particle size. The method of preliminary screening based on the upper limit screen and collection based on the lower limit screen refers to stacking the upper and lower limit screens in descending order of aperture size, with the upper limit screen on top and the lower limit screen on the bottom. The river sand to be screened is fed into the upper limit screen, where coarse particles exceeding the upper limit are retained. River sand with the correct particle size falls to the lower limit screen, where river sand with a particle size not lower than the lower limit is retained, and fine powder impurities and small river sand with excessively small particle sizes are discharged. The screened river sand refers to river sand whose fineness modulus meets the requirements after the above screening. The drying treatment of the screened river sand based on the raw material pretreatment unit refers to drying the screened river sand using the raw material pretreatment unit. The initially suitable river sand refers to screened river sand whose moisture content is still undetermined after drying treatment by the raw material pretreatment unit. The method for detecting the humidity of the initial suitable river sand refers to using a moisture meter to detect the humidity of the screened river sand. The river sand humidity refers to the humidity of the screened river sand. If the river sand humidity is greater than a preset humidity threshold, it indicates that the humidity is too high, which is not conducive to subsequent preparation. The humidity threshold is a preset threshold used to determine whether the screened river sand has too high humidity. The step of using the initial suitable river sand as screened river sand and returning to the drying process of the screened river sand based on the raw material pretreatment unit refers to re-drying and iterative optimization until the river sand humidity is less than the preset humidity threshold. The suitable river sand refers to screened river sand with a humidity less than the humidity threshold.

[0089] S3. Obtain the water type, cement type and optimal batching ratio. Based on the water type, cement type, suitable river sand, suitable crushed stone and suitable basalt fiber, weigh them according to the optimal batching ratio to obtain target water, target cement, target river sand, target crushed stone and target basalt fiber.

[0090] It should be explained that obtaining the water type, cement type, and optimal batching ratio involves weighing the water type, cement type, suitable river sand, suitable crushed stone, and suitable basalt fiber according to the optimal batching ratio to obtain the target water, target cement, target river sand, target crushed stone, and target basalt fiber, including:

[0091] Based on the parameter database, the water type, cement type, and optimal batching ratio are obtained, wherein the optimal batching ratio includes the cement content, river sand content, crushed stone content, and basalt fiber content.

[0092] Obtain the target water-cement ratio, and calculate the water content based on the target water-cement ratio and the cement content;

[0093] Based on the water type and cement type, suitable water and suitable cement are obtained. Based on the cement content, river sand content, crushed stone content, basalt fiber content and water content, the suitable water, suitable cement, suitable river sand, suitable crushed stone and suitable basalt fiber are weighed to obtain target water, target cement, target river sand, target crushed stone and target basalt fiber.

[0094] Furthermore, the method for obtaining water type, cement type, and optimal mix proportion based on the parameter database refers to querying and extracting the water type, cement type, and optimal mix proportion applicable to basalt fiber concrete for lock corridors from the parameter database. The water type refers to the recommended water source type, such as tap water. The cement type refers to the recommended cement grade, such as PO 42.5 ordinary Portland cement. The optimal mix proportion refers to the optimal range of different material proportions obtained by measuring the performance of concrete (such as compressive strength, crack resistance, etc.) under different mix proportions using single-factor experiments and orthogonal experiments, and then comparing and analyzing the performance of concrete with different mix proportions. The cement content, river sand content, crushed stone content, and basalt fiber content refer to the mass content of each material in a unit volume of concrete. In this invention, the contents are as follows: cement 220-300 parts, river sand 600-750 parts, crushed stone 1000-1200 parts, and basalt fiber 1.0-5.0 parts. The method for obtaining the target water-cement ratio refers to extracting the water-cement ratio suitable for the current optimal batching ratio from the parameter database. The target water-cement ratio can be determined through single-factor experiments. For example, while keeping the material content (i.e., batching ratio) constant, the water-cement ratio is controlled by adjusting the water content, and the performance corresponding to different water-cement ratios is measured. The water-cement ratio with the best performance under this batching ratio is selected. The target water-cement ratio refers to the mass ratio of water to cement, such as 0.35, used to calculate the water content. The method for calculating the water content based on the target water-cement ratio and cement content refers to multiplying the target water-cement ratio by the cement content to obtain the water content, which refers to the required amount of water. The method for obtaining suitable water and suitable cement based on the water type and cement type refers to selecting raw materials that meet the standards according to the type. The suitable water and suitable cement refer to the selected water and cement. The method for weighing suitable water, suitable cement, suitable river sand, suitable crushed stone, and suitable basalt fiber based on the cement content, river sand content, crushed stone content, basalt fiber content, and water content refers to using precision weighing equipment to accurately measure each material to obtain a fixed amount of different materials. The target water, target cement, target river sand, target crushed stone, and target basalt fiber refer to the amount of material obtained after weighing.

[0095] S4. Based on the mixing unit, the target river sand, target crushed stone and target basalt fiber are dry-mixed to obtain a dry-mixed mixture. Based on the mixing unit, the dry-mixed mixture, target water and target cement are wet-mixed to obtain target concrete.

[0096] It should be understood that the dry mixing process of the target river sand, target gravel, and target basalt fiber based on the mixing unit to obtain a dry mixture includes:

[0097] Obtain the initial dry mixing speed and initial dry mixing time;

[0098] The target river sand, target crushed stone and target basalt fiber are added to the mixing unit based on the preset feeding sequence, and the target river sand, target crushed stone and target basalt fiber in the mixing unit are stirred based on the initial dry mixing speed and initial dry mixing time to obtain an initial mixture.

[0099] The initial mixture is subjected to homogeneity analysis based on a pre-built image analysis unit to obtain analysis results, wherein the analysis results are homogeneous or non-homogeneous. If the analysis results are homogeneous, the initial mixture is identified as a dry mixture.

[0100] If the analysis result is non-uniform, then increase the dry mixing speed and extend the dry mixing time. Take the increased dry mixing speed and extended dry mixing time as the initial dry mixing speed and initial dry mixing time, respectively. Then return to the step of stirring the target river sand, target gravel and target basalt fiber in the mixing unit based on the initial dry mixing speed and initial dry mixing time, until the analysis result is uniform. Then the initial mixture is confirmed as a dry mixture.

[0101] It should be explained that the initial dry mixing speed refers to a preset starting speed, such as 150 rpm, and the initial dry mixing time refers to a preset starting time, such as 3 minutes. The preset feeding sequence refers to a specified order of addition. For example, the target crushed stone is added first, and after preliminary mixing to form a skeleton void, the target river sand is added. The river sand fills the void in the crushed stone skeleton, and a second dry mixing is performed to achieve a uniform mixture of coarse and fine aggregates. Finally, the target basalt fiber is added. Based on the feeding sequence, the fiber can be fully dispersed in the aggregate gaps to prevent fiber agglomeration. The method of mixing the target river sand, target crushed stone, and target basalt fiber in the mixing unit based on the initial dry mixing speed and initial dry mixing time refers to controlling the mixing unit to run at a specified speed and time. The initial mixture refers to the mixture after preliminary dry mixing. The method for analyzing the uniformity of the initial mixture based on the pre-built image analysis system involves using a camera to acquire images of the mixture, first processing the images to grayscale, and then evaluating the uniformity of grayscale using CV algorithms (such as grayscale variance or color distribution analysis). Since the river sand, gravel, and basalt fibers differ in color, the mixture image can be divided into multiple images of equal area. Color histograms are used to count the frequency of different color values ​​in the multiple images of equal area. The color distribution is analyzed based on the color histograms of different images to determine if it is uniform. If both grayscale and color values ​​are uniformly distributed, the analysis result is considered uniform; otherwise, it is considered non-uniform. The analysis result refers to the result of determining whether the initial mixture is uniform or non-uniform based on the above uniformity analysis. The pre-built image analysis unit refers to a system integrating machine vision. If the analysis result is non-uniform, the method of increasing the dry mixing speed and extending the dry mixing time involves incremental adjustments, such as increasing the speed by 20% and extending the time by 30%, followed by iterative optimization. The dry mixture refers to a mixture of dry materials that have been uniformly mixed.

[0102] Furthermore, the step of wet-mixing the dry mixture, target water, and target cement based on the mixing unit to obtain the target concrete includes:

[0103] Obtain the first mixing time and wet mixing speed, add the target cement to the dry mixture to obtain a cement mixture, and stir the cement mixture based on the first mixing time, wet mixing speed and mixing unit to obtain an initial wet mixture;

[0104] The target water is added to the initial wet mixture to obtain the initial concrete, and the actual fiber volume content, actual water-cement ratio and cement viscosity are obtained based on the initial concrete.

[0105] The second mixing time is calculated based on the actual fiber volume content, the actual water-cement ratio, and the cement viscosity, using the following formula:

[0106] ;

[0107] in, This indicates the second stirring time. This represents the adjustment coefficient. Indicates cement viscosity. Indicates water viscosity. This indicates the actual fiber volume content. , Indicates the base time;

[0108] The initial concrete is mixed based on the second mixing time and the mixing unit to obtain the target concrete.

[0109] It should be understood that the method for obtaining the first mixing time and wet mixing speed refers to extracting initial wet mixing parameters suitable for the current batching ratio (i.e., the optimal batching ratio) from a pre-constructed parameter database. The first mixing time and wet mixing speed ensure that the cement paste uniformly coats the aggregate and basalt fibers under the current batching ratio. This can be determined through pre-experiments. For example, under a certain batching ratio, the workability and viscosity of the initial wet-mixed mixture obtained after mixing at different speeds and times are measured through orthogonal experiments to see if they are within a preset suitable range. If so, the corresponding speed and mixing time are associated with the batching ratio and stored in the parameter database. The first mixing time and wet mixing speed refer to preset mixing duration (e.g., 30s) and speed (e.g., 120rpm), respectively, to ensure uniform cement distribution. The method for mixing the cement mixture based on the first mixing time, wet mixing speed, and mixing unit refers to controlling the mixing unit to run at a specified speed and time to mix the cement mixture. The initial wet-mixed mixture refers to the cement mixture after preliminary mixing. The method of adding the target water to the initial wet-mixed mixture to obtain the initial concrete refers to slowly adding water to avoid clumping. The method of obtaining the actual fiber volume content, actual water-cement ratio, and cement viscosity based on the initial concrete refers to first taking samples to obtain three sets of samples. For the first set of samples, the cement paste components in the sample are dissolved using dilute hydrochloric acid solution to separate the basalt fibers. The ratio of the mass of the basalt fibers to the mass of the sample is measured to obtain the actual fiber volume content. The second set of samples is dried in a constant-temperature drying oven to constant weight. The difference in mass before and after drying is used to determine the actual fiber volume content. The actual water consumption is calculated by using the weighed mass of the target cement as the amount of cementitious material. The ratio of the actual water consumption to the cement consumption is calculated to obtain the actual water-cement ratio. For the third group of samples, a Brookfield rotational viscometer is used to measure the real-time viscosity of the cement paste under the conditions of room temperature 20℃±2℃ and preset rotation speed (100r / min) to obtain the cement viscosity. The initial concrete refers to the initial wet-mixed mixture after the addition of water. The actual fiber volume content, actual water-cement ratio, and cement viscosity refer to the measured fiber volume ratio, the actual water-cement ratio, and the cement paste viscosity, respectively. The method for calculating the second mixing time based on the actual fiber volume content, actual water-cement ratio, and cement viscosity refers to substituting into the formula to calculate the adjustment time. The second mixing time refers to the final wet mixing duration calculated based on the actual parameters. The adjustment coefficient is a preset adjustment coefficient that can be adjusted according to the actual situation, with a default value of 1. The water viscosity refers to the standard viscosity of water, for example, the viscosity of water is 1 centipoise at 20°C. The actual water-cement ratio is indicated by the water consumption per cubic meter of concrete, and the reference time refers to the standard wet mixing time, which is 90 seconds in this invention. The method of mixing the initial concrete based on the second mixing time and the mixing unit refers to continuing wet mixing for the calculated time to ensure uniform fiber distribution. The target concrete refers to the completed concrete mixture.

[0110] S5. Based on the target concrete and the molding and curing unit, prepare the specimen to obtain a concrete specimen, and cure the concrete specimen to obtain a molded and cured specimen.

[0111] It should be explained that the process of preparing concrete specimens based on the target concrete and the molding and curing unit, and then curing the concrete specimens to obtain molded and cured specimens, includes:

[0112] Obtain the specimen dimensions, and then obtain the specimen mold based on the specimen dimensions;

[0113] The target concrete is poured into the specimen mold at a uniform speed, and the target concrete in the specimen mold is vibrated using a pre-constructed vibration device to obtain the vibrated specimen.

[0114] Based on the preset initial setting time, the pre-constructed room temperature environment, and the molding and curing unit, the vibrated specimens were left to stand to obtain concrete specimens.

[0115] Obtain the curing temperature and curing time for curing, and cure the concrete specimen based on the molding curing unit, curing temperature and curing time to obtain the molded curing specimen.

[0116] Furthermore, the method for obtaining specimen dimensions refers to extracting standard dimensions from a parameter database. The specimen dimensions refer to the standard dimensions used to prepare specimens of corresponding sizes. The method for obtaining specimen molds based on specimen dimensions refers to selecting molds corresponding to the specimen dimensions. The specimen molds refer to molds that match the specimen dimensions. The method for uniformly pouring the target concrete into the specimen mold refers to uniformly filling the specimen mold with the target concrete to avoid air bubbles. The method for vibrating the target concrete in the specimen mold based on a pre-constructed vibration device refers to vibrating it for 30-60 seconds using a vibrating table. The vibration device refers to equipment used for vibration. The vibrated specimen is the concrete specimen obtained through pouring and vibration. The method for allowing the vibrated specimen to stand based on a preset initial setting time, a pre-constructed room temperature environment, and a molding and curing unit refers to allowing it to harden in the molding and curing unit. The initial setting time refers to the initial hardening time of the concrete, such as 24 hours. The room temperature environment refers to a 20°C constant temperature room. The concrete specimen refers to the specimen after demolding following the above operations. The method for obtaining the curing temperature and curing time refers to obtaining the specific temperature and age for curing concrete specimens according to the "Test Procedure for Hydraulic Concrete" (SL / T 352-2020). The curing temperature and curing time refer to the temperature (20℃±2℃) and duration (28 days) used for curing the concrete specimens, respectively. The method for curing the concrete specimens based on the molding and curing unit, curing temperature, and curing time refers to using the molding and curing unit to control the temperature and maintain it at the curing temperature, and then curing the concrete specimens at the corresponding curing time. The molding and curing specimens refer to concrete specimens that have completed curing, and the molding and curing unit refers to a functional module used to realize the molding, static placement, and curing of basalt fiber reinforced concrete specimens for lock corridors.

[0117] S6. The performance of the molded and cured specimen is tested by the performance testing unit to obtain the compressive strength, crack strength and impact abrasion strength. The comprehensive performance index is calculated based on the compressive strength, crack strength and impact abrasion strength. If the comprehensive performance index is greater than or equal to the preset performance index threshold, the target concrete is determined to be high-strength concrete. Based on the high-strength concrete, the basalt fiber concrete of the raw material is prepared.

[0118] It should be understood that the performance testing of the molded and cured specimen based on the performance testing unit to obtain compressive strength, crack strength, and impact and abrasion resistance includes:

[0119] The compressive strength of the molded and cured specimen is obtained by performing a compressive strength test on the performance testing unit.

[0120] The axial tensile load is applied to the molded and cured specimen based on the performance testing unit, and the tensile force is measured on the molded and cured specimen based on the preset measuring device to obtain the crack resistance strength.

[0121] The impact and abrasion resistance strength was obtained by conducting a circular constraint experiment on the molded and cured specimen based on the performance testing unit.

[0122] It should be explained that the method for testing the compressive strength of the molded and cured specimens refers to applying axial pressure to the molded and cured specimens using a universal testing machine in accordance with the requirements of the "Test Procedure for Hydraulic Concrete" (SL / T 352-2020) until the specimen fails, recording the failure load and the area under pressure, and calculating the compressive strength by subtracting the area under pressure from the failure load. The compressive strength refers to the maximum pressure that the specimen can withstand per unit area, which is used to evaluate the bearing capacity of concrete. The performance testing unit refers to the functional module responsible for performance testing in the fiber-reinforced concrete preparation system. Optionally, the performance testing unit can be constructed using an electronic universal testing machine. The method of applying an axial tensile load to the molded and cured specimen and measuring the tensile force of the molded and cured specimen based on a preset measuring device refers to applying a uniform axial tensile force using the performance testing unit, while simultaneously monitoring the cracking of the specimen using a preset measuring device (such as a strain gauge). If cracking occurs, the tensile force at the time of cracking and the cross-sectional area of ​​the tensile region are recorded. The crack resistance strength is calculated by subtracting the cross-sectional area of ​​the tensile region from the tensile force at the time of cracking. The crack resistance strength refers to the ability of concrete to resist tensile failure. The measuring device refers to a sensor used to measure tensile force or compressive force. The abrasion resistance refers to the concrete's ability to resist erosion and wear. The method for conducting a circular restraint test on the molded and cured specimen involves first recording the initial weight and volume of the specimen, then abrading the specimen with quartz sand and water at a flow rate of 15 m / s. After abrasion, the abrasion time, the weight of the specimen after abrasion, and the abrasion volume are recorded. The abrasion resistance is calculated based on the initial weight, initial volume, abrasion time, abrasion weight, and abrasion volume. The calculation formula is shown below (this invention does not consider calculations after cracking of the molded and cured specimen):

[0123] ;

[0124] in, Indicates impact and abrasion resistance. Indicates the initial volume. Indicates the initial volume. Indicates the grinding volume. Indicates the quality of the grinding process. Indicates the grinding time.

[0125] Furthermore, the calculation of the comprehensive performance index based on the compressive strength, crack resistance, and impact abrasion resistance includes:

[0126] Based on the parameter database, obtain the benchmark compressive strength, benchmark crack strength, and benchmark impact and abrasion resistance.

[0127] The comprehensive performance index is calculated based on the aforementioned compressive strength, crack resistance, impact and abrasion resistance, reference compressive strength, reference crack resistance, and reference impact and abrasion resistance. The calculation formula is as follows:

[0128] ;

[0129] in, Indicates the overall performance index. Indicates compressive strength. Indicates crack resistance. Indicates impact and abrasion resistance. Indicates the reference compressive strength. Indicates the benchmark crack resistance strength. Indicates the reference impact and abrasion resistance. , and Indicates the weighting coefficient. This represents the effect coefficient.

[0130] It should be understood that the method of obtaining the benchmark compressive strength, benchmark crack strength and benchmark impact abrasion resistance based on the parameter database refers to querying and extracting the benchmark values ​​of the corresponding fiberless concrete from the parameter database. The benchmark compressive strength, benchmark crack strength and benchmark impact abrasion resistance refer to the compressive, crack and impact abrasion resistance values ​​of fiberless concrete under standard conditions (i.e., the material content and conditions are the same except for basalt fiber). The method for calculating the comprehensive performance index based on the compressive strength, crack resistance, impact abrasion resistance, reference compressive strength, reference crack resistance, and reference impact abrasion resistance refers to substituting the values ​​into a formula to calculate the comprehensive performance index. The comprehensive performance index is a dimensionless value that quantifies the overall performance of concrete. In the formula, the higher the compressive strength, crack resistance, and impact abrasion resistance, the higher the comprehensive performance index. Since compressive strength, crack resistance, and impact abrasion resistance are all positively correlated with concrete performance, a higher comprehensive performance index indicates better concrete performance. The weighting coefficients refer to the weights of compressive strength, crack resistance, and impact abrasion resistance, with default values ​​of 0.5, 0.2, and 0.3, respectively. The effect coefficients are adjustment factors that characterize the interaction effects between different indicators. Since there is a positive synergistic relationship between compressive strength, crack resistance, and impact abrasion resistance (for example, compressive strength both inhibits the initiation and propagation of microcracks to enhance crack resistance and enhances impact abrasion resistance by increasing matrix hardness), the effect coefficients are fixed as positive numbers, with a default value of 0.1. The method of determining the target concrete as high-strength concrete if the comprehensive performance index is greater than or equal to the preset performance index threshold means that when P ≥ the threshold (e.g., 1.2), the target concrete is judged as qualified high-strength concrete. The preset performance index threshold refers to the preset qualified limit threshold. The high-strength concrete refers to fiber-reinforced concrete that meets the requirements of the lock corridor. For example, with a performance index threshold of 1.2, the molded and cured specimen test results in a compressive strength of 60 MPa, a crack strength of 4.5 MPa, and an impact abrasion resistance of 6.0 h·m² / kg. The baseline compressive strength is 50 MPa, the baseline crack strength is 3.5 MPa, and the baseline impact abrasion resistance is 5.0 h·m² / kg. Substituting these values ​​into the calculation, the comprehensive performance index is calculated as follows: 0.41.2 + 0.31.286 + 0.31.2 + 0.1 × (1.21.286 + 1.2861.2 + 1.21.2) = 0.48 + 0.386 + 0.36 + 0.1 × (1.543 + 1.543 + 1.44) = 0.48 + 0.386 + 0.36 + 0.452 = 1.678 > 1.2. Therefore, the target concrete is determined to be high-strength concrete.

[0131] To address the problems described in the background art, this invention confirms the receipt of fiber-reinforced concrete preparation instructions and, based on these instructions, confirms the fiber-reinforced concrete preparation environment. This environment includes a fiber-reinforced concrete preparation system and raw materials. The preparation system comprises a raw material pretreatment unit, a mixing unit, a molding and curing unit, and a performance testing unit. The raw materials include river sand, crushed stone, and basalt fibers. Therefore, this invention considers the complex environment of high-strength requirements in basalt fiber-reinforced concrete preparation for lock corridors. By confirming the preparation environment, modular system integration is ensured, providing a reliable foundation for subsequent optimized preparation and thereby improving the overall suitability of concrete production. Adaptability and stability; obtaining target size: based on the raw material pretreatment unit and the target size, the raw materials are pretreated to obtain suitable river sand, suitable crushed stone, and suitable basalt fiber. It is evident that this invention introduces a size-targeted pretreatment mechanism to achieve fine optimization of raw materials, avoiding the particle size unevenness problem of traditional coarse processing, thereby improving fiber dispersibility and material compatibility; obtaining water type, cement type, and optimal batching ratio: based on the water type, cement type, suitable river sand, suitable crushed stone, and suitable basalt fiber, they are weighed according to the optimal batching ratio to obtain target water, target cement, target river sand, target crushed stone, and target basalt fiber. It is evident that this invention ensures precise control of element ratios through optimal batching and weighing, reducing waste. The invention optimizes the strength base, thereby improving the internal uniformity and mechanical properties of concrete. Based on the mixing unit, the target river sand, target crushed stone, and target basalt fiber are dry-mixed to obtain a dry mixture. Based on the mixing unit, the dry mixture, target water, and target cement are wet-mixed to obtain the target concrete. This embodiment of the invention employs a step-by-step dry-wet mixing mechanism to avoid fiber agglomeration and uneven moisture distribution, thereby improving mixing efficiency and concrete density. Based on the target concrete and the molding and curing unit, concrete specimens are prepared. The concrete specimens are then cured to obtain molded and cured specimens. This invention combines molding and curing to optimize crystal structure development and reduce premature aging. To mitigate the risk of cracking and ensure the representativeness and durability of the specimens, the performance testing unit performs performance tests on the molded and cured specimens to obtain compressive strength, crack strength, and impact abrasion resistance. A comprehensive performance index is calculated based on these strengths. If the comprehensive performance index is greater than or equal to a preset performance index threshold, the target concrete is identified as high-strength concrete. Based on this high-strength concrete, the preparation of basalt fiber concrete from the raw materials is achieved. It is evident that this invention calculates indices using multiple strength indicators to form a closed-loop quality verification, and the threshold judgment ensures high-strength output. Therefore, this invention can improve the strength, durability, and preparation efficiency of basalt fiber concrete for lock corridors.

[0135] The raw material pretreatment module 102 is used to obtain the target size and pretreat the raw materials based on the raw material pretreatment unit and the target size to obtain suitable river sand, suitable crushed stone and suitable basalt fiber.

[0136] The precise batching module 103 is used to obtain the type of water, the type of cement, and the optimal batching ratio. Based on the type of water, the type of cement, suitable river sand, suitable crushed stone, and suitable basalt fiber, the components are weighed according to the optimal batching ratio to obtain the target water, target cement, target river sand, target crushed stone, and target basalt fiber.

[0137] The target river sand, target crushed stone and target basalt fiber are dry-mixed using the mixing unit to obtain a dry-mixed mixture. The target concrete is then wet-mixed using the mixing unit with the dry-mixed mixture, target water and target cement.

[0138] Based on the target concrete and the molding and curing unit, a specimen was prepared to obtain a concrete specimen. The concrete specimen was then cured to obtain a molding and curing specimen.

[0139] The preparation verification module 104 is used to perform performance tests on the molded and cured specimens based on the performance testing unit to obtain compressive strength, crack strength and impact and abrasion resistance. Based on the compressive strength, crack strength and impact and abrasion resistance, a comprehensive performance index is calculated. If the comprehensive performance index is greater than or equal to a preset performance index threshold, the target concrete is determined to be high-strength concrete. Based on the high-strength concrete, the preparation of basalt fiber concrete from the raw materials is realized.
