[0040] It should be noted that the following detailed description is exemplary and is intended to provide further illustration of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0041] In the case of no conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0042] Embodiment 1

[0043] During the construction process of the existing highway engineering, most of the calculations and evaluations involved in the construction process rely on subjective human judgment, with low efficiency and easy to make mistakes; therefore, the present invention provides a digital highway engineering construction management cloud platform, through which various design data are calculated, retrieved, reused and evaluated, significantly reducing manual intervention and repetitive labor and improving the efficiency of engineering design and construction.

[0044] Next, in combination with Figures 1-3 , a digital highway engineering construction management cloud platform disclosed in this embodiment will be described in detail.

[0045] The digital highway engineering construction management cloud platform includes a user terminal, a cloud server, and a database. The user terminal is communicatively connected to the cloud server, and the cloud server is communicatively connected to the database. The database is used to store design data. The user terminal is used to obtain the concrete volume requirement in response to a user's input operation and send it to the cloud server. The cloud server is used to receive the concrete volume requirement and call the concrete mix ratio stored in the database. According to the concrete volume requirement and the concrete mix ratio, determine the dosage of each material in the concrete and calculate the concrete configuration result, and send the dosage of each material and the concrete configuration result to the user terminal.

[0046] Here, the concrete mix ratio includes the cement mix ratio, sand mix ratio, gravel mix ratio, admixture mix ratio, and water mix ratio, which are given by the laboratory through tests and stored in the database.

[0047] Further, determining the dosage of each material in the concrete according to the concrete volume requirement and the concrete mix ratio specifically includes:

[0048] (1) Determine the cement dosage according to the concrete cement mix ratio and the concrete volume requirement, expressed as:

[0049] m 水泥 =θ 水泥 *V 混凝土 ;

[0050] In the formula, θ 水泥 represents the cement mix ratio, and V 混凝土 represents the concrete volume requirement.

[0051] (2) Determine the sand dosage according to the sand mix ratio, sand moisture content, and concrete volume requirement, expressed as:

[0052]

[0053] In the formula, w 砂 represents the sand moisture content, and θ 砂 represents the sand mix ratio.

[0054] (3) Determine the gravel dosage according to the gravel mix ratio, gravel moisture content, and concrete volume requirement, expressed as:

[0055]

[0056] In the formula, θ 碎石 represents the gravel mix ratio, and w 碎石 represents the gravel moisture content.

[0057] (4) Determine the admixture dosage according to the admixture mix ratio and the concrete volume requirement, expressed as:

[0058] m 掺加剂= θ 掺加剂 *V 混凝土 ;

[0059] Where θ 掺加剂 represents the admixture mix ratio.

[0060] (5) Determine the water consumption according to the sand mix ratio, gravel mix ratio, admixture mix ratio, water mix ratio, and concrete volume requirement, expressed as:

[0061]

[0062] Where θ 水 represents the water mix ratio.

[0063] In the actual construction process, the raw materials sand and gravel themselves contain some water. Therefore, when calculating the dosage of sand and gravel, it is necessary to consider the water content of the raw materials sand and gravel and include this part of the water consumption in the raw material dosage of sand and gravel, making the calculation result more in line with the actual construction situation.

[0064] Furthermore, according to the dosage of each material in the concrete, the calculated concrete configuration results include:

[0065] (1) Calculate the actual water-binder ratio of the concrete according to the cement dosage, sand dosage, gravel dosage, admixture dosage, and water dosage, expressed as:

[0066]

[0067] Where m 水 represents the water dosage, m 砂 represents the sand dosage, w 砂 represents the water content of sand, m 碎石 represents the gravel dosage, w 碎石 represents the water content of gravel, m 水泥 represents the cement dosage, m 掺加剂 represents the admixture dosage.

[0068] (2) Calculate the difference value ε between the actual water-binder ratio and the preset theoretical water-binder ratio, and compare the difference value ε with the preset difference threshold ε 0 . If ε ≤ ε 0 , it is considered that the configured concrete meets the qualified requirements; if ε > ε 0 , it is considered that the configured concrete does not meet the qualified requirements, and the dosage of each material needs to be adjusted and re-proportioned.

[0069] As an implementation method, the user terminal is also used to obtain the concrete volume during the construction of bored cast-in-place piles; among them, the concrete volume is generated by the cloud server according to the bored cast-in-place pile design parameters stored in the database.

[0070] During the construction process of bored cast-in-place piles, it is necessary to calculate the volume of concrete. By calling the design parameters of bored cast-in-place piles stored in the database, the volume of concrete poured during the construction process of bored cast-in-place piles can be directly calculated, which is expressed as:

[0071]

[0072] In the formula, v represents the volume of concrete poured, with the unit of m 3 ; R represents the designed diameter of the pile, with the unit of mm; H represents the designed elevation of the pile top, with the unit of mm; l represents the designed elevation of the pile bottom, with the unit of mm.

[0073] During the construction process of bored cast-in-place piles, it is necessary to dynamically adjust the length of the conduit according to the actual situation of concrete pouring to ensure the safe progress of construction; before pouring, the length of the conduit = the depth of the hole before pouring - the suspension of the conduit. Before pouring, the measured suspension value of the conduit (generally 0.3 to 0.5 m) is input; further, the user terminal is also used to respond to the user's input operation, obtain the volume of concrete already poured for the bored cast-in-place pile and send it to the cloud server. The cloud server receives the volume of concrete already poured, calls the initial length of the conduit and the bottom area of the drilling stored in the database, and determines the real-time length of the conduit according to the volume of concrete already poured, the initial length of the conduit and the bottom area of the drilling and sends it to the user terminal; the real-time length of the conduit is expressed as:

[0074] l = l 0 - v 0 / s;

[0075] In the formula, l represents the real-time length of the conduit, with the unit of m; l 0 represents the initial length of the conduit, with the unit of m; v 0 represents the volume of concrete already poured, with the unit of m 3 ; s represents the bottom area of the drilling, with the unit of m 2 .

[0076] Users can adjust the length of the conduit in real time according to the received real-time length of the conduit and the suspension value of the conduit to ensure the normal progress of the pouring process.

[0077] As an implementation method, the user terminal is also used to obtain the construction lofting value of the project and send it to the cloud server. The cloud server receives the construction lofting value of the project, calls the corresponding project design value stored in the database, conducts a consistency check according to the construction lofting value of the project and the corresponding project design value, and generates the construction qualification rate of the project and sends it to the user terminal. Specifically, it includes:

[0078] (1) Compare the construction lofting value of the project with the corresponding project design value, judge the qualification status of each inspection item, and obtain the qualification rate of each inspection item.

[0079] Exemplarily, as shown below, there are 5 major items and 9 minor items in the inspection items, and each minor item has a separate pass rate, which are respectively denoted as E1, …, E9.

[0080] Here, calculate the total sample number N and the number of samples N0 that meet the allowable deviation for each item respectively. The pass rate of a single item = N0 / N.

[0081]

[0082]

[0083] Here, the actual engineering construction lofting values can be imported into the user terminal through relevant devices such as GPS and total station.

[0084] (2) According to the project types of the engineering construction lofting values, use the analytic hierarchy process to determine the weight matrix, the corresponding eigenvector and the consistency index between different types of projects.

[0085] Exemplarily, first, for 9 different minor items, make pairwise comparisons respectively to construct a pairwise judgment matrix A = (a ij ) 9×9 , in the matrix, the element a ij represents the importance degree of the comparison between the i-th factor and the j-th factor.

[0086] Here, the larger a ij is, the greater the influence of the i-th factor on the total goal compared to the j-th factor. The specific value meanings are shown in the following table. The value range of a ij satisfies: ①a ij ∈(0, 9]; ②a ii = 1; ③a ij ×a ji = 1.

[0087]

[0088]

[0089] Then, use Ax = λx to calculate the eigenvalues and eigenvectors of matrix A, and calculate the maximum eigenvalue λ max and the eigenvector x.

[0090] Then, check the consistency index of the obtained weights. Specifically, calculate the consistency index where n = 9; calculate the consistency ratio index If CR ≤ 0.1, it is considered that the obtained result meets the consistency test condition and the calculation result is valid; otherwise, it is considered that the obtained result does not meet the consistency test condition and needs to be adjusted and calculated again.

[0091] When the obtained result meets the consistency test condition, normalize the obtained eigenvector x: The normalized eigenvector is obtained, which is the weight of different items. After obtaining the weights of different items, the overall qualification rate can be calculated by the following formula:

[0092]

[0093] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
