In the complex and technology-intensive field of shaft construction, traditional concrete pouring methods have gradually shown many limitations. These methods often rely on manual operation and experience judgment, and it is difficult to ensure the accuracy and efficiency of pouring. At the same time, they face challenges such as high safety risks and difficult quality control. Especially in the construction of deep wells and large-diameter shafts such as those in this hydropower project, the uniformity, density and pouring speed of concrete have become key factors restricting the quality and progress of the project.
[0003] With the rapid development of science and technology, especially the widespread application of technologies such as the Internet of Things, big data, and artificial intelligence, revolutionary changes have been brought about in the pouring of concrete in shaft construction. A new type of intelligent concrete pouring system has emerged. The system integrates advanced technologies such as high-precision sensors, intelligent control algorithms, and remote monitoring platforms, and realizes comprehensive perception, precise control, and intelligent decision-making of the concrete pouring process, providing technical support for the construction of the shaft concrete of this project.

The invention can realize autonomous pouring operations on floors in complex construction environments, solves the impact of vibration and noise during manual pouring operations on the health of operators, has low requirements on operators, is widely applicable, and improves the efficiency of pouring.
[0005] It can be seen that the intelligent concrete pouring system and method have the following problems: the invention uses a stand to synchronously lift the entire system, installs a panoramic monitoring camera to reduce the technical requirements of the operator, and improves the concrete pouring efficiency. However, the invention lacks monitoring of the concrete pouring process and cannot ensure the uniformity of the concrete pouring process, which leads to low concrete pouring quality. Summary of the invention
[0006] To this end, the present invention provides an intelligent concrete pouring system in shaft construction to overcome the problem in the prior art that the concrete pouring process lacks monitoring and the uniformity of the concrete during the pouring process cannot be ensured, resulting in low concrete pouring quality.
[0007] To achieve the above object, the present invention provides an intelligent concrete pouring system in shaft construction, comprising:

[0010] A vibration mechanism, used to vibrate concrete to disperse the concrete, comprising a first vibration component arranged at the connection between the feed horizontal pipe and the second feed vertical pipe and facing the outer side of the pipe wall at the bottom of the shaft, and a second vibration component distributed on the support mold;
[0011] A control mechanism is respectively connected to the feeding mechanism, the detection mechanism and the vibration mechanism, and is used to determine whether the feeding state of the concrete meets the standard according to the pressure distribution height, adjust the first vibration component based on the feeding state that does not meet the standard, determine the adjustment of the second vibration component and / or the diverter component according to the stone distribution uniformity under the feeding state that meets the standard, and determine whether the pouring process of the concrete meets the standard based on the pouring speed of the concrete.
[0012] Furthermore, the material distribution component includes a material distribution center and a plurality of material distribution pipes, and the material distribution center is provided with a plurality of rotating paddles distributed at equal intervals.
[0013] Further, the control mechanism determines that the concrete feeding state does not meet the standard based on the comparison result that the distribution height is greater than the preset distribution height;
[0014] The control mechanism determines that the concrete feeding state meets the standard based on the comparison result that the distribution height is less than or equal to the preset distribution height.
[0015] Further, the control mechanism, based on the judgment result that the concrete feeding state does not meet the standard, subtracts the distribution height from the preset distribution height to obtain the height difference percentage, and the control mechanism determines to increase the first vibration intensity of the first vibration component based on the comparison result that the height difference percentage is greater than the preset height difference percentage;
[0016] The control mechanism is further configured to determine to increase the first vibration frequency of the first vibration component based on a comparison result that the height difference percentage is less than or equal to the preset height difference percentage.
[0017] Furthermore, the control mechanism obtains the stone distribution uniformity based on the judgment result that the concrete feeding state meets the standard, and determines that the vibration process does not meet the standard based on the comparison result that the stone distribution uniformity is less than the preset stone distribution uniformity.
[0018] Further, the control mechanism subtracts the stone distribution uniformity from the preset stone distribution uniformity to obtain a uniformity difference, and determines to adjust the second vibration component based on the comparison result that the uniformity difference is less than or equal to the preset uniformity difference, wherein,
[0019] The control mechanism calculates a first difference percentage between the preset uniformity difference and the uniformity difference, and determines to adjust a second vibration intensity or a second vibration frequency of the second vibration component based on a comparison result between the first difference percentage and the first preset difference percentage.

[0026] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention determines whether there is accumulation in the process of concrete feeding by setting a pressure detection component and a position detection component. Once the concrete is accumulated, the pressure on the wall of the first feeding vertical pipe will increase. Based on the distribution of abnormal pressure, the first vibration component is adjusted in a highly targeted manner to achieve the purpose of rapid feeding and alleviate the problem of concrete accumulation; a diversion center is set, and a re-mixing space is set for the falling concrete to avoid the problem of segregation of concrete with a large slump due to gravity during the falling process.

[0028] Furthermore, the present invention determines whether there is accumulation of concrete during the falling process based on the distribution height of abnormal pressure. The accumulation of concrete will cause a decrease in the feeding speed, a slowdown in the pouring progress and a decrease in the performance of the concrete. The vibration of the first vibration component is enhanced specifically according to the accumulation of concrete, the falling of the concrete is accelerated, the accumulation problem is alleviated, and the pouring quality of the concrete is improved.
[0029] Furthermore, the present invention determines whether the vibration of concrete during the pouring process meets the standard based on the uniformity of gravel distribution in the poured concrete. The vibration will accelerate the flow of concrete, reduce the phenomenon of local aggregation or sinking of gravel, and increase the density of concrete. The improvement of density helps to further promote the uniform distribution of gravel in concrete and avoid large-scale sinking or floating of gravel during vibration, thereby improving the pouring uniformity and further improving the pouring quality of concrete.
[0030] Furthermore, the pouring speed of the concrete of the present invention determines whether the pouring process meets the standards. If the pouring speed is too fast, a temperature difference will occur between the surface and the interior of the concrete, causing cracks in the concrete. If the pouring speed is too slow, the fluidity of the concrete will gradually decrease, affecting the uniformity and density of the pouring, and will also cause low pouring efficiency. The pouring speed is monitored and adjustments are made to situations that do not meet the standards, thereby further improving the pouring quality of the concrete. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] A vibration mechanism, used to accelerate the flow of concrete, comprising a first vibration component arranged at the connection between the material discharge horizontal pipe 3 and the second material discharge vertical pipe 7 and facing the outer side of the pipe wall at the bottom of the shaft, and a second vibration component distributed on the support mold 11;
[0045] A control mechanism is respectively connected to the feeding mechanism, the detection mechanism and the vibration mechanism, and is used to determine whether the feeding state of the concrete meets the standard according to the pressure distribution height, adjust the first vibration component based on the feeding state that does not meet the standard, determine the adjustment of the second vibration component and / or the diverter component according to the stone distribution uniformity under the feeding state that meets the standard, and determine whether the pouring process of the concrete meets the standard based on the pouring speed of the concrete.
[0046] Specifically, the pressure detection component includes a pressure sensor 4, such as a strain gauge pressure sensor 4. The specific model and parameters are not limited.

It can detect the pressure distribution position; the radar detection component includes a radar transmitter, a radar receiver, a radar signal processor and a radar controller. The specific model and parameters are not limited. It can detect the distribution of stones in the poured concrete and the concrete pouring height.
[0047] Specifically, the pouring speed of concrete is the ratio of the pouring height to the corresponding time.
[0048] Specifically, the present invention determines whether there is accumulation in the process of concrete feeding by setting a pressure detection component and a position detection component. Once the concrete is accumulated, the pressure on the wall of the first feeding vertical pipe 2 will increase. Based on the distribution of abnormal pressure, the first vibration component is adjusted in a highly targeted manner to achieve the purpose of rapid feeding and alleviate the problem of concrete accumulation; a diversion center 8 is set, and a re-mixing space is set for the falling concrete to avoid the problem of segregation of concrete with a large slump due to gravity during the falling process; a plurality of diversion pipes 9 are set to quickly transport the concrete to the position to be poured and reduce the flow time of the concrete, thereby improving the uniformity of pouring; by setting a plurality of rotating blades 10 in the diversion center 8, the mixing effect of the concrete in the diversion center 8 is improved, thereby further improving the uniformity of pouring; by determining whether the pouring process meets the standard through the judgment of the pouring speed, and adjusting the process that does not meet the standard, the pouring efficiency is improved while improving the pouring uniformity.
[0049] Specifically, the material distribution component includes a material distribution center and a plurality of material distribution pipes, and the material distribution center is provided with a plurality of rotating blades 10 distributed at equal intervals.
[0050] Specifically, the number of the material distribution pipes and the rotating blades 10 is determined according to the design requirements and is not specifically limited. In the embodiment of the present invention, the number of the rotating blades 10 and the number of the material distribution pipes are preferably both four.
[0051] Specifically, the present invention stirs the falling concrete by setting a material distribution center and a plurality of rotating blades 10 in the material distribution center. The greater the stirring speed, the better the performance of the concrete and the better the pouring quality of the concrete. The stirring speed of the rotating blades 10 is determined according to the slump of the concrete. The greater the slump, the greater the stirring speed.
[0052] Specifically, the control mechanism determines that the concrete feeding state does not meet the standard based on the comparison result that the distribution height is greater than the preset distribution height;
[0053] Based on the comparison result that the distribution height is less than or equal to the preset distribution height, it is determined that the discharge state of the concrete meets the standard.
[0054] Specifically, the preset height is determined according to the slump of concrete. The smaller the slump, the easier it is for concrete to accumulate in the discharge pipe, and the smaller the value of the preset height is. There is no specific limitation.
[0055] Specifically, the control mechanism, based on the condition that the concrete feeding state does not meet the standard, subtracts the distribution height from the preset distribution height to obtain the height difference percentage, and determines the adjustment method of the first vibration component based on the comparison result of the height difference percentage and the preset height difference percentage.
[0056] Specifically, if the height difference percentage is greater than the preset height difference percentage, it is determined to increase the first vibration intensity of the first vibration component;
[0057] If the height difference percentage is less than or equal to the preset height difference percentage, determining to increase the first vibration frequency of the first vibration component;
[0058] Among them, the first difference between the height difference percentage and the preset height difference percentage is positively correlated with the increase in vibration intensity, and the second difference between the preset height difference percentage and the height difference percentage is positively correlated with the increase in vibration frequency.
[0059] It can be understood that, the larger the first difference is, the greater the increase in vibration intensity is; and the larger the second difference is, the greater the increase in vibration frequency is.
[0060] Specifically, the control mechanism obtains the stone distribution uniformity based on the condition that the concrete feeding state meets the standard, and determines that the vibration process does not meet the standard based on the comparison result that the stone distribution uniformity is less than the preset stone distribution uniformity.
[0061] Specifically, the calculation process of stone distribution uniformity is:
[0062] Based on the radar detection component, the distribution ratio of stones in each particle size range in the poured concrete area is obtained;
[0063] Compare each distribution ratio with the corresponding concrete particle size gradation. The ratio of the number of particle size ranges that meet the particle size gradation to the total number of particle size gradations is the stone distribution uniformity.
[0064] Specifically, the particle size gradation of the concrete in the embodiment of the present invention refers to the particle size range of the gravel in the concrete and the corresponding proportion of the particle size range. The greater the uniformity of the gravel distribution, the better the pouring quality of the concrete.
[0065] Specifically, the control mechanism subtracts the stone distribution uniformity from the preset stone distribution uniformity to obtain a uniformity difference, and determines to adjust the second vibration component based on a comparison result that the uniformity difference is less than or equal to the preset uniformity difference;
[0066] The adjusting of the rotating paddle 10 is determined based on the comparison result based on the uniformity difference being greater than the preset uniformity difference.
[0067] Specifically, the preset stone distribution uniformity value range is set to [60%, 100%], and 80% is preferred in the embodiment of the present invention.
[0068] Specifically, the value range of the preset uniformity difference is set to [0, 30%], and 10% is preferred in the embodiment of the present invention.
[0069] Specifically, the control mechanism calculates a first difference percentage between the preset uniformity difference and the uniformity difference, and determines to adjust a second vibration intensity or a second vibration frequency of the second vibration component based on a comparison result of the first difference percentage and the first preset difference percentage.
[0070] Specifically, the value range of the first preset difference percentage is set to [0, 5%], and 3% is preferred in the embodiment of the present invention.
[0071] Specifically, if the first difference percentage is greater than the first preset difference percentage, determining to adjust the second vibration intensity of the second vibration component;
[0072] If the first difference percentage is less than or equal to the first preset difference percentage, it is determined to adjust the second vibration frequency of the second vibration component.
[0073] Specifically, the difference between the first difference percentage and the first preset difference percentage is recorded as a first percentage, and the difference between the first preset difference percentage and the first difference percentage is recorded as a second percentage.
[0074] The adjustment amplitude of the vibration intensity is positively correlated with the first percentage, and the adjustment amplitude of the vibration frequency is positively correlated with the second percentage.
[0075] It can be understood that the larger the first percentage is, the larger the adjustment range of the vibration intensity is; and the larger the second percentage is, the larger the adjustment range of the vibration frequency is.
[0076] Specifically, the control mechanism calculates a second difference percentage between the uniformity difference and the preset uniformity difference, and determines to increase the rotation speed of the rotating blade 10 based on a comparison result of the second difference percentage and the second preset difference percentage.
[0077] Specifically, the value range of the second preset difference percentage is set to [6%, 10%], and 7% is preferred in the embodiment of the present invention.
[0078] Specifically, the control mechanism determines to use the first speed adjustment coefficient to adjust the rotation speed of the rotating blade 10 based on the comparison result that the second difference percentage is greater than the second preset difference percentage;
[0079] The control mechanism determines to use the second speed adjustment coefficient to adjust the rotation speed of the rotating blade 10 based on the comparison result that the second difference percentage is less than or equal to the second preset difference percentage.
[0080] Specifically, the value range of the first speed adjustment coefficient is set to [1.4, 1.8], and 1.5 is preferably selected in the embodiment of the present invention; the value range of the second speed adjustment coefficient is set to [1.01, 1.39], and 1.3 is preferably selected in the embodiment of the present invention.
[0081] Specifically, the control mechanism determines that the concrete pouring process does not meet the standard based on a comparison result that the pouring speed is less than a first preset pouring speed or greater than a second preset pouring speed, wherein the second preset pouring speed is greater than the first preset pouring speed.
[0082] Specifically, the first preset pouring speed and the second preset pouring speed are determined according to the design requirements of concrete.
[0083] Specifically, the control mechanism subtracts the first preset pouring speed from the pouring speed to obtain a first speed difference percentage, or subtracts the pouring speed from the second pouring speed to obtain a second speed difference percentage;
[0084] Based on the first speed difference percentage, several adjustment modes are set for the material feeding speed, and the adjustment amplitude of the electric valve 13 in each adjustment mode is positively correlated with the first speed difference percentage;
[0085] Based on the second speed difference percentage, several adjustment methods are set for the material discharge speed, and the adjustment range of the electric valve 13 in each adjustment method is positively correlated with the second speed difference percentage.
[0086] It can be understood that, the larger the first speed difference percentage is, the larger the reduction range of the electric valve 13 by each adjustment method is; and the larger the second speed difference percentage is, the larger the increase range of the electric valve 13 by each adjustment method is.
[0087] Specifically, the electric valve 13 adjusts the pipe diameter. The smaller the range covered by the valve, the larger the pipe diameter, and the faster the concrete feeding speed. The larger the range covered by the valve, the smaller the pipe diameter, and the slower the concrete feeding speed.
