[0081] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the related content and not to limit the present application.

[0082] It should also be noted that, for the sake of brevity, only parts of the application are shown in the drawings.

[0083] The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0084] The method in the present embodiment can be run on a paver alone, or a server can be provided, and the relevant calculations and controls can be performed in the server, and the parameters can be transmitted to the paver / vibration exciter and other engineering construction machinery for display or control.

[0085] Embodiment one

[0086] A digital construction method of a high earth-rock dam, comprising:

[0087] In a first step, ground parameters of a high earth-rock dam construction area are obtained, which can include the position of the construction area, the ground flatness of the construction area, the length of the construction area, the width of the construction area, the ground relief of the construction area, the longitude of the construction area, and the latitude of the construction area.

[0088] This step can be designed by implementing a construction plan, and only the final result needs to be input.

[0089] In a second step, final parameters of the high earth-rock dam are obtained, and the high earth-rock dam is divided into layers to obtain layer parameters stacked in sequence. The final parameters can include the height of the high earth-rock dam, the width of the high earth-rock dam, the length of the high earth-rock dam, the specific position of the high earth-rock dam relative to the construction area, and the filling material of the high earth-rock dam. Therefore, the construction cannot be completed at one time, and a layer-by-layer stacking method needs to be used. Therefore, in order to facilitate construction, the high earth-rock dam can be divided into n layers, and for the sake of description, they are sequentially set as the 1st layer, the 2nd layer, …, the (n-1)th layer, and the nth layer from bottom to top.

[0090] For each layer, the layer parameters include layer flatness, paving thickness, layering trajectory, layering width, etc.

[0091] Thirdly, according to the layering data in the second step, the first layer is constructed first, and then the second layer is constructed on the first layer after the construction of the first layer is completed, and the layers are stacked in turn until the construction of the nth layer is completed, and finally the construction of the high earth-rock dam is completed.

[0092] The specific steps of the third step are described below.

[0093] S1, determine the position of the layer to be paved, and determine the paving surface parameters according to the layer to be paved; the method comprises:

[0094] If the paving layer is the bottom layer (i.e. the first layer), the paving surface parameters are determined according to the ground parameters of the construction area;

[0095] If the paving layer is not the bottom layer (i.e. the second layer and above), the paving surface parameters are determined according to the layer parameters of the lower layer; when the paving layer is the xth layer, the paving surface parameters are determined according to the layer parameters of the (x-1)th layer, wherein 2≤x≤n.

[0096] The paving parameters include coordinate parameters, path parameters (traveling trajectory of the paver and the vibrating roller), paving thickness parameters (thickness of each paving layer), vibrating force parameters, and rolling frequency.

[0097] S1.1, determine the unit division parameters according to the paving surface parameters; determine the unit division parameters according to the longitude of the construction area, the latitude of the construction area, the layering width, and the paving width of the paver, and the unit division parameters include unit boundary lines.

[0098] Because the width of the paver is limited, in order to reduce the back-and-forth movement of the paver, according to the relevant parameters of the construction area, each layer of the high earth-rock dam is divided into multiple units, for example, the first layer is divided into the first unit, the second unit, …, the m1-1 unit, and the m1 unit, and the m1 units are spliced to form the first layer.

[0099] Similarly, the second layer is divided into m2 units, and the third layer is divided into m3 units.

[0100] S1.2, determine the paving parameters according to the unit division parameters;

[0101] S1.3, receive the paving parameters, and determine the paving travel trajectory according to the coordinate parameters in the paving parameters;

[0102] According to the paving surface parameters, the coordinate parameters of the strip region are determined, and the coordinates include longitude, latitude and altitude; and according to the coordinate parameters of the strip region, the traveling track of the paver is drawn, that is, the middle line of the strip region is taken as the traveling track of the paver.

[0103] In order to avoid reciprocating movement, the width of the strip region is set to be equal to the width of the paver, that is, under normal circumstances, only the strip region needs to be traveled along in sequence, that is, the paving of one layer can be completed.

[0104] S1.4, receiving the paving parameters, and according to the paving thickness parameter in the paving parameters, determining the paving thickness, the unloading speed and the traveling speed of the paver;

[0105] By determining the composition of the paving material, including the water content and the viscosity of the composition, the unloading speed and the traveling speed of the paver are determined, so that they can meet the demand of the paving thickness after cooperation.

[0106] S1.5, receiving the paving parameters and the paving traveling track, and according to the paving traveling track, determining the traveling track of the vibrating roller; generally, the width of the vibrating roller is less than the width of the paver, so the vibrating roller may need to reciprocate to meet the rolling of the paving layer, and therefore the vibrating roller needs to reciprocate multiple times, so the traveling track of the vibrating roller needs to be determined according to the paving traveling track, so as to finally meet the rolling of the entire paving surface.

[0107] S1.6, receiving the paving parameters, and according to the vibrating force parameter in the paving parameters, determining the vibrating force of the vibrating roller;

[0108] S1.7, receiving the paving parameters, and according to the rolling number of times in the paving parameters, determining the reciprocating traveling number of times of the vibrating roller;

[0109] The above two steps complete the rolling of the paving surface.

[0110] S2, according to the paving traveling track, the unloading speed and the traveling speed of the paver, paving the dam material;

[0111] Various data such as paving data and track data are transmitted to the paver, and the paving of the dam material can be realized by displaying on the paver or directly controlling the paver.

[0112] S3, according to the traveling track of the vibrating roller, the vibrating force of the vibrating roller and the reciprocating traveling number of times of the vibrating roller, rolling the dam material;

[0113] After paving, according to the parameters in S1, the vibrating roller can be directly controlled or the parameters to be maintained can be displayed, so as to realize the rolling of the dam material.

[0114] S4, repeating steps S1-S3, completing the multi-layer paving of the high earth-rock dam, i.e., completing the 1st layer, the 2nd layer,..., the nth layer in turn, and finally realizing the construction of the high earth-rock dam.

[0115] The calculation method of the rolling times, the exciting force parameter, the paving thickness parameter, the traveling speed, and the paving width of the paver includes:

[0116] Determine the paving efficiency of the paver: Wherein, E is the construction efficiency, h is the paving thickness parameter, i is the paving width of the paver, n is the rolling times, and v is the traveling speed.

[0117] Establish a nonlinear mapping relationship between the compaction density of the high earth-rock dam and the parameters: ρ = f(n, h, v, j), wherein ρ is the compaction density, and j is the exciting force.

[0118] Determine the combination of the paving parameters with the maximum stability of the compaction density control: Wherein, α k is the partial derivative of the kth parameter when the value of the scheme is taken, and K is the number of paving parameters.

[0119] Establish a paving parameter optimization model for the construction of the earth-rock dam:

[0120] opt(G) = f(E, ρ, S)

[0121] s.t.{Y min ≤(n, v, h, i, j)≤Y max}, wherein Y min and Y max are the minimum value and the maximum value of the variable value.

[0122] Establish a paving parameter optimization model that comprehensively considers the construction efficiency and quality assurance:

[0123] Wherein G is the comprehensive optimization target, λ E , λ ρ , and λ S are the weights of the construction efficiency, the rolling quality, and the stability; considering the importance of each target, the AHP method is adopted, and the relative importance of the construction efficiency, the rolling quality, and the stability is in the ratio of 3:3:1.

[0124] Take G as the fitness of the firework algorithm, and determine the maximum value G max and the minimum value G min of the fitness according to the firework algorithm.

[0125] The implementation of the firework algorithm includes the following steps:

[0126] 1) Randomly generate some fireworks in the specific solution space, each of which represents a solution in the solution space.

[0127] 2) Calculate the fitness value of each of the fireworks according to the fitness function, and generate sparks according to the fitness value. The number of sparks is calculated based on the idea of immune concentration in immunology, that is, the better the fitness value, the more the number of sparks generated.

[0128] 3) Generate sparks in the radiation space of the fireworks according to the actual situation of the search problem and the actual situation of the fireworks. The size of the explosion amplitude of a certain firework is determined by the fitness value of the firework on the function, the larger the fitness value, the larger the explosion amplitude, and vice versa. Each spark represents a solution in the solution space. In order to ensure the diversity of the population, the fireworks need to be properly mutated, such as Gaussian mutation.

[0129] 4) Calculate the optimal solution of the population, determine whether the requirements are met, if yes, stop searching, if not, continue iteration. The initial value of iteration is the best solution obtained this time and other selected solutions.

[0130] Change the values of n, v, and j, and solve the paving parameter optimization model to obtain G', if G min <G'<G max , the paving parameter value is obtained; if not, iterate the values of n, v, and j to solve again.

[0131] Example two

[0132] This embodiment explains the specific method of S1.5, the method for determining the running track of the vibration roller includes:

[0133] Determine the width ratio of the paving machine to the width of the vibration roller, if the ratio is 1, the vibration roller runs once to complete a rolling, if the ratio is 2, the vibration roller needs to run twice to complete it. Therefore, the specific situation can be adjusted to ensure that the paving surface can be rolled.

[0134] According to the running track of the paving machine, the running track of the vibration roller is determined, and according to the above ratio, the running track of the vibration roller can be determined.

[0135] Install a positioning device on the vibration roller, and collect the running position and rolling track of the vibration roller through the positioning signal, and through the installation of the positioning signal, the specific position of the vibration roller can be determined.

[0136] According to the traveling position of the vibration roller and the vibration force parameters, the vibration force corresponding to the position of the vibration roller is determined, and the vibration roller is controlled to output the vibration force, because different positions may require different vibration forces, such as the vibration force requirement of the middle region is greater than that of the edge region, so when the vibration roller moves to the edge region, the vibration force can be appropriately reduced. The positioning device selected in this embodiment can be a satellite positioning device or a local area network positioning device, that is, signal generators are installed at different positions in the use site, and the positioning of the vibration roller is realized through the communication between the signal generators and the positioning device on the vibration roller.

[0137] According to the rolling track and the rolling number of the vibration roller, the number of reciprocating travel of the vibration roller is determined.

[0141] A laser receiver is arranged on the bulldozer plate of the paver, and the laser emitter and the laser receiver are paired, so that the laser receiver can detect the distance between the bulldozer plate and the reference surface.

[0142] Before paving, the laser reference surface is determined (i.e. the position of the laser emitter is adjusted), and the height of the laser emitter is adjusted so that the height difference between the laser emitter and the paving surface is equal to the paving thickness.

[0143] During paving, the distance h1 between the laser emitter and the laser receiver is obtained in real time. If the paver is automated, the height of the bulldozer plate is controlled through the program of the paver itself. If the paver is not automated, h1 can be displayed, and then the operator of the paver adjusts the height of the bulldozer plate according to the displayed data.

[0144] The height of the bulldozer plate of the paver is controlled, and h1=0.

[0145] Embodiment four

[0146] After step S2 is completed, the paving thickness needs to be detected to avoid the situation that the paving thickness is insufficient, so the detection method provided in this embodiment includes:

[0147] This embodiment takes the xth layer paving as an example.

[0148] After the previous (x-1th layer) rolling, the height H1 of the paver relative to the ground of the construction area is obtained.

[0150] Obtaining the height difference of H1 and H2, and determining whether to compare it with the paving thickness H0;

[0151] If H0=H2-H1, it is determined that the paving is qualified, and step S3 is performed, that is, the thickness of the rolling operation can be performed; if H0≠H2-H1, it is determined that the paving is unqualified, and step S2 is repeated, that is, the thickness is corrected.

[0152] It includes two cases, that is, too thick or too thin.

[0153] If H0>H2-H1, the paver is controlled to perform secondary paving to increase the thickness of the paving layer.

[0154] If H0<H2-H1, the part of the paving material is scraped.
