Description

Technical Field

[0001] The invention relates to the technical field of concrete curing, and in particular to a construction site concrete curing device. Background Art

[0002] With the increase in construction demand, concrete plays an increasingly important role in the construction industry. In the process of using concrete, in order to ensure that the concrete can achieve the expected strength, durability and overall performance, the concrete needs to be cured. In the process of concrete curing, it is necessary to analyze the environment to optimize the curing effect. For example, compared with the concrete curing at non-construction sites, the environment in which the concrete is located is more complex, especially the dust at the construction site is more serious than that at non-construction sites. During the curing process of concrete, the dust covering the surface of the concrete will prevent the full penetration of water, causing the surface to dry too quickly, affecting the strength and durability, and the fine particles in the dust adhere to the surface of the concrete, forming a pollution layer, which affects the subsequent coating and protective layer adhesion.

[0003] Existing concrete curing devices generally use spraying equipment to spray the formed concrete at a fixed time and at a fixed point. This curing method can achieve good results for concrete without dust influence, but for concrete at the construction site, it is easy to stimulate dust and cause the dust to adhere to the concrete surface to form a pollution layer and an isolation layer, thereby reducing the curing effect of the concrete, which is easy to cause insufficient overall construction efficiency and waste of resources.

DETAILED DESCRIPTION

[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, a construction site concrete curing equipment proposed by the present invention is described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0018] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0019] The specific scheme of the construction site concrete curing equipment provided by the present invention is described in detail below with reference to the accompanying drawings.

[0020] An embodiment of a construction site concrete curing equipment: See also Figure 1 , which shows a construction site concrete curing equipment provided by an embodiment of the present invention. The construction site concrete curing equipment of this embodiment is as follows Figure 1 and Figure 2 As shown in the figure: 22 is a first dust sensor; 23 is a second dust sensor; 41 is a spray port; 42 is a dust removal motor; 44 is an air supply device, and 45 is an air supply port. The construction site concrete curing equipment of this embodiment includes a first dust sensor 22, a second dust sensor 23, a spray port 41, a dust removal motor 42, a dust removal port 43, an air supply device 44, an air supply port 45, an information collection module, a data calculation module, and an instruction execution module.

[0021] The information collection module is used to respectively use the first dust sensor 22 and the second dust sensor 23 to obtain the first dust concentration and the second dust concentration in the environment where the concrete of the construction site is located in the current time period.

[0022] The data calculation module is used to obtain the first-class dust growth index at each moment according to the change of the first dust concentration at all moments before each moment in the current time period; and obtain the influence parameters of the second-class dust on concrete curing at each moment by combining the time interval between each moment in the current time period and the next concrete curing, the second dust concentration at each moment and the first-class dust growth index.

[0023] The instruction execution module is used to adjust the operating power of the dust removal motor 42 and the air supply equipment 44 based on the difference in the second dust concentration at each moment in the current time period and the current moment; based on the difference in the impact parameters of the second type of dust on concrete curing at each moment in the current time period and the current moment, adjust the water output of the spray port 41.

[0024] The construction site concrete curing equipment provided in this embodiment is to achieve effective curing of concrete in the construction site environment to avoid the negative impact of dust at the construction site on the curing effect of the concrete. Therefore, the main logic is: use the information collection module to collect the dust concentration data around the concrete to be cured at the construction site, and then use the data calculation module to analyze the impact of the dust concentration data on the concrete curing, and then use the dust treatment system and concrete curing system in the instruction execution module to perform concrete curing under dust conditions.

[0025] First, the information collection module of the concrete curing equipment at the construction site is used to collect dust concentration data around the concrete to be cured at the construction site. The specific process is as follows: the influence of dust on concrete curing is mainly divided into two aspects. The first aspect is the direct impact item, that is, the dust covering the surface of the concrete, which will absorb part of the moisture and cause pollution to the surface of the concrete when the concrete is cured; the second aspect is airborne dust. This type of dust floats in the air and will eventually fall to the ground due to gravity. Part of it will fall on the surface of the concrete, causing pollution during curing. Therefore, this embodiment detects these two types of dust separately and obtains two types of environmental dust concentration data. The first type of environmental dust concentration data is obtained by using the first dust sensor 22 to detect the dust concentration in the environment where the concrete is located at the construction site to obtain the first dust concentration. The second type of environmental dust concentration data is obtained by starting the air supply device 44 in the instruction execution module, so that the device generates wind force to supply air to the concrete surface along the air outlet, stirring up the deposited dust on the concrete surface, and then using the second dust sensor 23 of the information acquisition module to detect the concentration of the surface deposited dust of the concrete stirred up by the air supply device 44, and obtain the second dust concentration. In this embodiment, the collection frequency of the first dust concentration and the second dust concentration is set once every second, that is, a first dust concentration and a second dust concentration are collected every second. In specific applications, the implementer can set the collection frequency according to specific circumstances. In this embodiment, the first dust sensor 22 and the second dust sensor 23 are used to collect the first dust concentration and the second dust concentration in the environment where the concrete of the construction site is located at each collection moment in the current time period. The current time period is a set of all historical moments whose time interval between the current moment is less than or equal to the preset time length. In this embodiment, the preset time length is 20 minutes. In specific applications, the implementer can set it according to specific circumstances. It should be noted that the moments mentioned later are all collection moments.

[0026] In this embodiment, the first dust sensor 22 and the second dust sensor 23 are of the SDS026 industrial dust sensor type, and the specific parameter information is shown in Table 1: Table 1 Parameter information of SDS026 industrial dust sensor The impact of the two types of dust concentration data on concrete curing can be divided into multiple situations. The first type of dust can be continuously transformed into the second type of dust. The second type of dust directly affects the curing of concrete as follows: First, when the first type of floating dust is less and has a slower growth trend, and the second type of deposited dust is more, for the first type of floating dust, the concrete is cured using conventional irrigation volume, and then covered with covering materials. Because the floating dust is less and grows more slowly, the amount of dust that finally falls on the concrete surface before the next irrigation is less, and the moisture absorption of the cured concrete is less, so the first type of floating dust has less impact on the final curing effect of the concrete. The second type of deposited dust is more, and the impact on concrete curing is less effective curing moisture, so higher power is required to remove the dust on the concrete surface, and a larger irrigation volume should be given to avoid incomplete removal of deposited dust.

[0027] Secondly, when there is a lot of first-type floating dust, the growth trend is fast, and there is a lot of second-type deposited dust, a large amount of first-type floating dust will fall onto the concrete surface and convert into more second-type deposited dust. Therefore, it is necessary to use a larger sprinkler volume and a higher dust removal power to remove the deposited dust on the concrete surface, and to maintain the wetness of the concrete surface for a long time to avoid the falling of dust after the maintenance is completed and affect the maintenance effect.

[0028] Then, when the first type of floating dust is small, the growth trend is not fast, and the second type of deposited dust is small, the conversion speed of the first type of dust to the second type of dust is not fast enough, and the second type of deposited dust on the concrete surface is small, so the concrete can be cured using conventional sprinkler volume and dust removal power.

[0029] Finally, when there is more first-type floating dust and a faster growth trend, and less second-type deposited dust, there is a sufficient conversion speed between the first-type dust and the second-type dust. Therefore, a larger amount of sprinkler irrigation is needed to keep the concrete surface moist for a long time. If there is less second-type deposited dust, conventional dust removal power can be used to remove the dust on the concrete surface.

[0030] Based on the above characteristics, the data calculation module evaluates the growth of the first type of dust according to the difference in the first dust concentration at each moment in the current time period and its adjacent moments.

[0031] Specifically, the average value of the first dust concentration at each moment in the current time period and its adjacent moments is taken as the first average value at the corresponding moment, that is, each moment in the current time period corresponds to a first average value. Next, a moment in the current time period is taken as an example for explanation. The method provided in this embodiment can be used to process other moments in the current time period. Any moment in the current time period is recorded as a candidate moment. According to the overall difference between the first average value of all moments before the candidate moment in the current time period and the first dust concentration at the candidate moment, the first type of dust growth index at the candidate moment is obtained. Specifically, the difference between the first average value of each moment before the candidate moment in the current time period and the first dust concentration at the candidate moment is calculated, and recorded as the first difference between each moment before the candidate moment in the current time period and the candidate moment; the average value of the first difference between all moments before the candidate moment in the current time period and the candidate moment is determined as the first type of dust growth index at the candidate moment.

[0032] In this embodiment, a specific calculation formula for the first type of dust growth index is given. The first type of dust growth index at the t-th moment in the current time period can be expressed as: in, It represents the first type of dust growth index at the tth moment in the current time period, Indicates the tth moment before the current time period. The first dust concentration at the moment, Indicates the tth moment before the current time period. The first dust concentration at the moment, Indicates the tth moment before the current time period. +1 moment's first dust concentration, Indicates the first dust concentration at the tth moment in the current time period.

[0033] Indicates the tth moment before the current time period. The first average value at the moment, Indicates the tth moment before the current time period. The first difference between the moment and the tth moment, Used to characterize the overall difference between the first average value of all moments before the tth moment in the current time period and the first dust concentration at the tth moment.

[0034] Since the first type of dust has a lag effect on the maintenance of concrete, which is specifically manifested in that the dust in the current environment continues to fall on the surface of the concrete to form the second type of dust, the dust at the tth moment in the current time period is only the beginning of the impact on the maintenance of concrete. It is necessary to consider the changes in the first type of dust after the tth moment. Therefore, the data calculation module uses the first dust concentration in the historical moment before the tth moment to calculate the second type of dust. A simple prediction is made on the change trend of the concentration data of the first type of dust after the moment, so as to obtain the The growth trend of the first-class dust concentration after the t-th moment is recorded as the first-class dust growth index at the t-th moment.

[0035] In this embodiment, the average of the first dust concentration at any moment before the t-th moment and the first dust concentration at the adjacent moments before and after is used as the smoothed value of the first dust concentration at any moment before the t-th moment, and then the difference between the smoothed value at this moment and the first dust concentration at the t-th moment is used as the first difference between this moment and the t-th moment, which is used to characterize the relative trend value of the first type of dust data at this moment and the t-th moment. The purpose of using the smoothed value to replace the data at each moment is to prevent outlier data from appearing at any moment, and to smooth the data to make the data trend more obvious. Finally, the average of the difference values ​​between the data at all historical moments and the data at the t-th moment is used as the predicted trend of the subsequent moments of the t-th moment. The larger the value, the more obvious the first type of dust is in an obvious growth trend after the t-th moment.

[0036] The impact of the first type of dust on the maintenance of concrete is indirect and continuous, so the interval between the current maintenance time and the next maintenance time is judged. The longer the distance between the current maintenance time and the next maintenance time, the greater the concentration of the first dust at the current moment, and the more obvious the continuous growth trend, then the more the first type of dust will be converted into the second type of dust after this maintenance of concrete, and the more serious the impact on this maintenance will be.

[0037] Next, according to the first dust concentration at the candidate moment, the first type of dust growth index at the candidate moment, and the time interval between the candidate moment and the next concrete curing, the influence parameter of the first type of dust at the candidate moment on concrete curing is obtained; specifically, the negative correlation normalization result of the first type of dust growth index at the candidate moment is obtained; according to the first dust concentration at the candidate moment, the time interval between the candidate moment and the next concrete curing, and the negative correlation normalization result, the influence parameter of the first type of dust at the candidate moment on concrete curing is obtained, the first dust concentration and the time interval are both positively correlated with the influence parameter of the first type of dust at the candidate moment on concrete curing, and the negative correlation normalization result is negatively correlated with the influence parameter of the first type of dust at the candidate moment on concrete curing.

[0038] According to the first characteristic value corresponding to the candidate time and the influence parameter of the first type of dust on concrete curing at the candidate time, the influence parameter of the second type of dust on concrete curing at the candidate time is obtained, and the first characteristic value and the influence parameter of the first type of dust on concrete curing are both positively correlated with the influence parameter of the second type of dust on concrete curing. The first characteristic value corresponding to the candidate time is the ratio between the second dust concentration at the candidate time and the average value of the second dust concentration at all times in the current time period.

[0039] Among them, the positive correlation relationship means that the dependent variable will increase as the independent variable increases, and the dependent variable will decrease as the independent variable decreases. It can be an additive relationship, a multiplicative relationship, etc., which is determined by actual application; the negative correlation relationship means that the dependent variable will decrease as the independent variable increases, and the dependent variable will increase as the independent variable decreases. It can be a subtractive relationship, a division relationship, etc.

[0040] In this embodiment, specific calculation formulas for the influence parameters of the first type of dust on concrete curing and the influence parameters of the second type of dust on concrete curing are given. The influence parameters of the first type of dust on concrete curing and the influence parameters of the second type of dust on concrete curing at the t-th moment in the current time period can be expressed as: in, It represents the impact parameter of the first type of dust on concrete curing at the tth moment in the current time period, Indicates the first dust concentration at the tth moment in the current time period, It represents the first type of dust growth index at the tth moment in the current time period, Indicates the current moment, Indicates the sequence number of the time in the current time period. Indicates the absolute value symbol, T indicates the number of moments in the current time period, Indicates the second dust concentration at the tth moment in the current time period, It represents the impact parameter of the second type of dust on concrete curing at the t-th moment in the current time period, and e represents a natural constant.

[0041] Indicates the negative correlation normalized result of the first type of dust growth index at the t-th moment in the current time period. When calculating the impact parameter of the second type of dust on concrete curing, it is necessary to consider not only the size of the second type of dust data itself, but also the conversion of the first type of dust to the second type of dust. Therefore, this embodiment uses the impact parameter of the first type of dust on concrete curing as the adjustment value of the impact parameter of the second type of dust on concrete curing, and takes the relative size of the second type of dust at the t-th moment and the second type of dust in the historical moment as the main body to obtain the impact parameter of the second type of dust on concrete curing. The larger the value, the more dust covers the concrete surface at the t-th moment, and more dust will cover the concrete surface in the future.

[0042] So far, the method provided in this embodiment has been used to obtain the impact parameters of the second type of dust on concrete curing at each moment.

[0043] Finally, the execution parameters of different systems in the concrete curing instruction execution module are obtained according to the impact of dust on concrete curing.

[0044] The maintenance of concrete in the concrete curing equipment mainly utilizes the spray port 41, dust removal motor 42, dust removal port 43 and air supply equipment 44 in the instruction execution module to achieve surface dust removal and surface spraying of the concrete, which can be specifically divided into two aspects. The first aspect is the dust removal system, and the second aspect is the spray system.

[0045] The purpose of the dust removal system is only to remove the dust on the current concrete surface. Therefore, we only need to consider the second type of covering dust on the concrete surface at the current moment. There is no need to consider the subsequent conversion of the first type of dust into the second type of dust. The concentration data of the second type of dust can be compared with the data at historical moments.

[0046] The difference between the second dust concentration at the current moment and the second dust concentration at each moment in the current time period is recorded as the second difference between the current moment and each moment in the current time period; the first normalized value of the average value of the second difference between the current moment and all moments in the current time period is calculated, and the power parameter is obtained by subtracting the first normalized value from the preset adjustment parameter. The power parameter can be expressed as: Where W represents the power parameter, T represents the number of moments in the current time period, Indicates the second dust concentration at the tth moment in the current time period, Indicates the second dust concentration at the current moment. To preset adjustment parameters, Represents the normalization function.

[0047] In this embodiment, the preset adjustment parameter is 0.5. In specific applications, the implementer can set it according to specific circumstances.

[0048] The greater the dust concentration at the tth moment in the current time period, the stronger the power required to treat the dust on the concrete surface corresponding to the current moment; Indicates the second difference between the current moment and the tth moment in the current time period, The first normalized value represents the average value of the second difference between the current moment and all moments in the current time period, and the average value of the second difference between the current moment and all moments in the current time period. When the first normalized value is larger, more powerful power is needed to process the dust on the concrete surface corresponding to the current moment, that is, the power parameter is larger.

[0049] After obtaining the power parameters, the product of the power parameters and the operating power of the dust removal motor 42 at the current moment is used as the new operating power of the dust removal motor 42; the product of the power parameters and the operating power of the air supply device 44 at the current moment is used as the new operating power of the air supply device 44.

[0050] The purpose of the spraying system is to keep the concrete moist before the next spraying. Therefore, it is necessary to consider the covering dust at the current moment and the impact of the subsequent conversion of the first type of dust into the second type of dust on the subsequent concrete surface. Therefore, the impact parameters of the second type of dust on concrete curing are used for calculation.

[0051] Specifically, the difference between the impact parameter of the second type of dust on concrete curing at the current moment and the impact parameter of the second type of dust on concrete curing at each moment in the current time period is recorded as the third difference between the current moment and each moment in the current time period; the second normalized value of the average value of the third difference between the current moment and all moments in the current time period is calculated, and the water output parameter is obtained by subtracting the second normalized value from the preset adjustment parameter. The water output parameter can be expressed as: Among them, S represents the water output parameter, It indicates the impact parameter of the first type of dust on concrete curing at the current moment.

[0052] Indicates the third difference between the current moment and the t-th moment in the current time period, represents the average value of the third difference between the current moment and all moments in the current time period, The second normalized value represents the average value of the third difference between the current moment and all moments in the current time period. When the second normalized value is larger, the water output parameter is larger.

[0053] After the water output parameter is obtained, the product of the water output parameter and the water output of the spray port 41 at the current moment is used as the new water output of the spray port 41. Figure 3 As shown, this figure is a schematic diagram of the data processing flow corresponding to the concrete curing equipment at the construction site.

[0054] At this point, the new operating power of the dust removal motor 42, the new operating power of the air supply device 44 and the new water output of the spray port 41 are obtained by the above method, and the instruction execution module adjusts them, and the air supply device 44 operates at the new operating power to agitate and blow up the dust on the surface of the concrete; then the dust removal motor 42 absorbs the agitated and blown dust through the dust removal port 43 at the new operating power, and the spray port 41 completes spraying the concrete at the new water output.

[0055] The construction site concrete curing equipment provided by the present embodiment includes a first dust sensor 22, a second dust sensor 23, a spray port 41, a dust removal motor 42, an air supply device 44, an information collection module, a data calculation module and an instruction execution module. The information collection module collects a first dust concentration and a second dust concentration in the environment where the construction site concrete is located in the current time period. The first dust concentration is used to reflect the concentration of dust in the air, and the second dust concentration is used to reflect the concentration of dust covered on the concrete surface. Since the first type of dust has a lagging effect on the curing of concrete, which is specifically manifested in that the amount of dust in the current environment is continuously partially landed on the surface of the concrete to form the second type of dust, the data calculation module calculates the first type of dust according to the change of the first dust concentration at all times before each time in the current time period. A simple prediction is made on the changing trend of the concentration data, and the first type of dust growth index is obtained to reflect the growth trend of the first type of dust concentration. Then, the time interval between each moment and the next concrete curing in the current time period, the second dust concentration at each moment and the first type of dust growth index are combined to obtain the impact parameters of the second type of dust on concrete curing at each moment. The instruction execution module adjusts the operating power of the dust removal motor 42 and the air supply equipment 44 based on the difference in the second dust concentration between each moment in the current time period and the current moment. Based on the difference in the impact parameters of the second type of dust on concrete curing at each moment in the current time period and the current moment, the water output of the spray port 41 is adjusted, thereby completing the curing of the concrete, improving the curing effect of the concrete, and avoiding waste of resources.

Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present invention should be included in the protection scope of the present invention.
