calculating the amount of sand needed for manufacturing the concrete according to the amount of the concrete;
and according to the sand amount required by manufacturing the concrete, discharging sand which does not meet the preset condition and sand which meets the preset particle size but exceeds the sand amount out of the tunnel.
The quantity of concrete required by tunnel construction can be known through pre-design, and the pre-set conditions comprise the size of a pre-set particle size, strength and the like.
In an embodiment of the present invention, after adjusting the operating parameters of the crushing device, the transmission device, the screening device, and the sand making device according to the sand information, the method further includes:
and when the stone powder content or grading data of the sandstone in the characteristic parameters cannot be adjusted to the preset target sandstone physical parameters, carrying out screening treatment and/or blending treatment on the sandstone.
The content of the stone dust in the sand can be obtained by the following method:
step 100: target machine-made sand image data is acquired.
In step 100, the stacked machine-made sand may be directly captured at any angle and distance by using an image capturing device. Image capture devices include, but are not limited to, cell phones, cameras, video cameras, surveillance cameras, and the like.
It is to be understood that the target manufactured sand image data refers to an image of a manufactured sand heap within a target area, which may be acquired from any angle.
Step 200: inputting the target machine-made sand image data into a trained stone powder content detection model, and determining stone powder content detection result data in machine-made sand corresponding to the target machine-made sand image data based on the output of the stone powder content detection model.
In step 200, the surface image information of the machine-made sand may be input into the model trained by machine learning, and the stone powder content of the machine-made sand may be automatically calculated. The stone powder content detection model is obtained by training based on a preset machine learning model in advance, and the machine learning model can be a deep learning model, such as a convolutional neural network.
Specifically, the application of the scheme provided in the steps 100 to 200 does not require detection instruments and reagents for testing, and adopts a non-contact image acquisition and artificial intelligent calculation mode, so that the image acquisition equipment is portable and convenient for image information sampling; the stone powder content of the machine-made sand is obtained in real time, target information can be obtained in real time after the image information of the surface of the machine-made sand is collected, the stone powder content can be rapidly checked in scenes such as real-time adjustment and construction in the production process of the machine-made sand, and time and labor are saved; the method does not depend on the experience of engineering personnel, eliminates human errors and can better control the accuracy of output results.
From the above description, it can be known that, in the embodiment of the present application, when the content of stone dust in sand is obtained, through image obtaining and artificial intelligence technology, non-contact detection of the content of machine-made stone dust can be achieved, the intelligence degree, the automation degree, the convenience and the efficiency of the non-contact intelligent real-time detection process of stone dust content can be effectively improved, and the accuracy and the real-time performance of the non-contact intelligent real-time detection result of the content of machine-made stone dust can be effectively improved, so that real-time adjustment of machine-made sand in the production process can be achieved, and the engineering personnel can perform fast check work under the scenes without detecting instruments, experimental reagents and the like, the problems of poor accuracy caused by unrepresentative sampling and large consumption of manpower and material resources required by repeated experiments can be avoided, and the present application can be applied to various application scenes, for example, in a machine-made sand selling scene, without the need of the detection personnel to arrive at the scene, the machine-made sand detection result can be provided for the buyer only according to the machine-made sand image acquired in a non-contact mode, and for example, in a machine-made sand production scene, a producer can provide the machine-made sand detection result for the producer through stone powder content adjustment or stone powder content quality inspection in the machine-made sand only according to the machine-made sand image acquired in the non-contact mode.
For example, the adjustment capability of the powder content in the sand making link reaches the limit and still cannot meet the requirement of the target powder content interval:
A. if the content of the stone powder is higher than the upper limit value of the characteristic parameter target interval of the sand, the sand can be screened by screening equipment, and a specific screening example diagram can be seen in fig. 3; B. if the content of the stone powder is lower than the lower limit value of the target interval of the characteristic parameters of the sand, the requirement can be met by adding the stone powder according to the calculated proportion, and a specific screening example diagram can be seen in fig. 4. A top view of the screening device and the diverting device (fig. 3 and 4) can be seen in fig. 5.
Specifically, for A, assume that the target interval of the dust content of the sand is [ a, b ]](where a and b are real numbers, b is greater than or equal to a, and a, b is equal to [0,1]]) The measured powder content of the sand is c, and c belongs to (b, 1)]Then, by means of a real-time separation device, the ratio is
The sand is separated from the continuous conveying equipment (such as a belt conveyor), the separated sand is thoroughly screened (mechanical screening or water washing is adopted, the mechanical screening is adopted preferentially, the screened mud is reserved for standby, and the screened sand without powder is all continuously mixed to obtain the sand with the powder content [ a, b ]]Sand within the range; preferably, if the optimum target for the dust content is p (where p is a real number, p ∈ [ a, b ]]) The proportion of the real-time separation and screening is
For case A, its corresponding screenThe sub-device is shown in figure 3. Specifically, in case B, a method of continuously adding stone powder to the sand with low powder content on the continuous transportation equipment in real time is adopted, and if the actually measured powder content is c, the production speed of the sand is V m3Min, the adding speed of the stone powder should be
(where ρ is the density of sand in kg/m3) (ii) a Preferably, if the optimum target for the dust content is p (where p is a real number, p ∈ [ a, b ]]) The real-time, continuous addition of stone dust to the sand with low dust content on the continuous transport equipment should be at a rate of
(where ρ is the density of sand in kg/m3). It is specifically stated that new formulas formed by changes in the computational units and algebraic meanings should be protected or considered to have been disclosed by the present invention as long as the idea is adopted. And finally, conveying the sand to the next link through conveying equipment.
For gradation in sand, it can be obtained by:
step 300: determining the oversize ratio constraints of sand particles with different particle sizes according to the preset variation gradient of the oversize ratio of the component, and determining a component oversize ratio series set according to the oversize ratio constraints of the sand particles.
It will be appreciated that both the sand fineness modulus and the particle size distribution are determined by the fractional rejects of sand, since the detection of these two characteristic parameters can be converted into a detection of the fractional rejects, i.e. into the reject ratio.
Optionally, the application determines a set of a series of scoring rejects for selecting the sand particle image.
For example, first, the set of the score series may be set as S ═ { ej }, where ej is an element of the set S, and each element ej may represent a score combination case.
Then, by setting a reasonable variation gradient d of the fraction, for example, d is 0.1% or an integral multiple thereof, one fraction per pore size of the fraction itself is represented by Bi, j, and the particle size is assumed to be B1, j — B6, j (for example, B1%, which is referred to as B1) in descending order.
In other embodiments of the present application, there is actually a sieve bottom, i.e. a sieve bottom which is a particle which has leaked through 0.15mm, and is also designated as a parameter B7, j.
Finally, according to the definition of the score triage and the set score triage gradient, for any element ej in the set S, it can be represented by Bi, j, and there is the following constraint between Bi, j:
by traversing the conditions of any ej which meet the above constraints, a complete set S of the scoring rejects rate series can be obtained.
Step 400: and obtaining a sand particle characteristic image data set according to the sand correspondingly configured by each sub-scale screen residue combination in the sub-scale screen residue rate series set.
Optionally, before obtaining the sand particle characteristic image, sand with each partial-screen-residue-rate combination aperture in each partial-screen-residue-rate series set may be screened according to the specification requirements, and sufficient amount is reserved and stored in corresponding containers, and then corresponding sand is prepared according to each partial-screen-residue combination in the partial-screen-residue-rate series set determined in step 300, and then a corresponding image is obtained for the sand of each residual-rate combination.
Optionally, the apparatus for acquiring an image includes: image sensors such as mobile phones, digital cameras, and modular cameras. Photographs of different angles, distances (distance of the image sensor to the sand surface) and resolutions can be acquired, wherein preferably fixed angle, resolution, and distance photographs can be acquired.
It is understood that the same fineness modulus or particle size distribution may correspond to different screen residue combinations (ej), and in addition, different parent rocks, different origins and different types (natural sand and machine-made sand) may be screened, and each type of sand may be independently blended to obtain different screen residue combinations (ej), or a plurality of different types of sand may be blended to obtain different screen residue combinations (ej).
Step 500: and training a preset machine learning model according to the sand particle characteristic image data set, and performing sand grading prediction operation according to the trained machine learning model to obtain a sand grading prediction result.

The adjustment capability of the grain size grading in the sand making ring section reaches the limit and still cannot meet the requirements of a target grading area: the treatment can be carried out by means of flow division-selective screening. The calculation idea of sieving is the same as the powder content. Specifically, for the sand in the sand making ring section, the adjustment capability of the sand grain size is limited and still cannot meet the target grading requirement, the interval of the sand deviating from the maximum and minimum target intervals (for example, the sand content in a certain interval is significantly higher than the target interval, the sand content in a certain interval is significantly lower than the target interval, the sand content in a certain interval is significantly higher than the target interval, and the sand content in another interval is significantly lower than the target interval) can be calculated, the sand content in the interval has the most significant influence on the grading, and the treatment can be performed by adopting a shunting-selective screening means, specifically: A. if the content of the sand in a certain particle size interval (for example: 1.18mm-2.36mm) is obviously higher than the upper limit value of the target interval, the sand can be screened by a screening device; B. if the content of sand in a certain particle size interval (for example: 0.60mm-1.18mm) is significantly lower than the lower limit value of the target interval, the sand in the interval can be added by calculating the proportion to achieve the requirement. C. If the sand content in one interval is obviously higher than that in the target interval, and the sand content in the other interval is obviously lower than that in the target interval, the step A can be firstly carried out, and then the step B can be carried out. (Note: significantly higher, significantly lower, means that the sand grading is within the target interval by changing the sand content in this interval only)
The specific method comprises the following steps: for A, assuming that the target content of sand in the interval of 1.18mm-2.36mm is [ a, b ] (wherein a, b are real numbers, b is larger than or equal to a, and a, b is equal to [0,1]), the target content of the actually measured sand in the interval of 1.18mm-2.36mm is c, and c is equal to (b, 1) ], separating the sand with the proportion of [ (c-b)/(c-b c), (c-a)/(c-ac) ] from continuous transportation equipment (such as a belt conveyor) through real-time separation equipment, screening the separated sand, removing the sand in the interval of 1.18mm-2.36mm, storing the screened sand in a corresponding storage space (a separate storage space with a certain pore diameter can be arranged), continuously back-blending all the screened sand without the interval of 1.18mm-2.36mm to obtain the content of the sand in the interval of 1.18mm-2.36mm [ a, b ] within the range; preferably, if the optimum target for sand content in the interval 1.18mm-2.36mm is p (where p is a real number, p e a, b), the ratio separated in real time for sieving is (c-p)/(c-pc). For the a case, it corresponds to fig. 3.
Specifically, for the B case, the target sand content in the interval 0.60mm-1.18mm is assumed to be [ a, B ]](where a and b are real numbers, b is greater than or equal to a, and a, b is equal to [0,1]]) The target content of the actually measured sand in the interval of 0.60mm-1.18mm is c, and c belongs to (0, a)]Continuously adding sand in the interval of 0.60mm-1.18mm to the sand on the continuous transportation equipment in real time in a corresponding storage space (an independent storage space with a certain sieve pore interval can be arranged), and if the production speed of the sand is V m3Min, the sand in the interval is added to the sand on the continuous transportation equipment by using the corresponding storage space at the speed of [ (a-c)/(1-a) rho V, (b-c)/(1-b) rho V]kg/min (where ρ is the density of sand in kg/m)3) (ii) a Preferably, the optimum target for sand content if in the interval 0.60mm-1.18mm is p (where p is the ratio of the total sand content to the total sand content of the sandp is a real number, p is ∈ [ a, b ]]) The rate of real-time, continuous addition of sand in the interval 0.60mm-1.18mm to the sand on the continuous transport equipment should be (p-c)/(1-p) ρ V kg/min (where ρ is the density of the sand in kg/m3)。
Specifically, for the case C, if the content of sand in a certain particle size interval (e.g., 1.18mm-2.36mm) is significantly higher than the upper limit value of the target interval, and the content of sand in the interval of 0.60mm-1.18mm is significantly lower than the lower limit value of the target interval, the sand can be divided by the step a according to the calculation idea of the case a, and the sand divided by 1 is screened and then all the sand is continuously back-blended, so that the sand higher than the certain interval is in the target interval; and through the step B, firstly, recalculating the actual gradation of the sand, and then calculating the adding rate of the sand to be added according to the calculation thought of the condition B. It is specifically stated that new formulas formed by changes in the computational units and algebraic meanings should be protected or considered to have been disclosed by the present invention as long as the idea is adopted.
And after the sand making process is finished, conveying the sand to the next link through conveying equipment.
