Description

Technical Field

[0001] The invention relates to the technical field of slip form sliding, and in particular to an intelligent judgment system and method for the sliding timing of concrete in an extra-large special-shaped vertical shaft. Background Art

[0002] In large-scale water conservancy projects such as hydropower stations, surge tanks are one of the key components, and their function is to adjust the head pressure of the turbine generator set to meet the needs of load changes in the power system. In terms of the hydraulic slipforms for the lining of super-large special-shaped surge tanks, there have been reports on the hydraulic slipforms for circular surge tanks, hydraulic slipforms for vertical shafts, and integrated hydraulic formwork for lining and middle partitions. However, the diameter of circular surge tanks is basically limited to about 30m, and the lining shape is relatively regular.

[0003] In the concrete construction of super-large special-shaped shafts, the concrete pouring of the shaft structure adopts the slipform construction technology. By continuously pouring concrete and sliding the slipform, the shaft structure can be quickly constructed. However, for super-large special-shaped shafts, their shapes are complex, and the control of concrete pouring and slipform sliding is more difficult. Among them, the accurate judgment of the timing of sliding is a key factor in ensuring construction quality and construction safety. The traditional method of judging the timing of sliding mainly relies on the experience of construction personnel. The accuracy of the judgment is affected by many factors such as the experience level of construction personnel, environmental factors, and concrete characteristics. It is easy to cause various problems in the concrete sliding process, such as substandard concrete quality, low construction efficiency, and increased construction safety risks.

[0004] Specifically, the existing technology mainly has the following problems:

[0005] Single basis for judgment: The traditional judgment on the timing of sliding mainly relies on the experience of construction workers. The basis for judgment is relatively single and cannot fully consider the influence of multiple factors such as the characteristics of concrete, construction environment, and construction progress.

[0006] Poor judgment accuracy: The experience levels of construction workers vary greatly, and the accuracy of judgment is limited by personal experience, which can easily lead to misjudgment and quality problems during the concrete sliding process.

[0007] Low construction efficiency: Due to poor accuracy of judgment, repeated testing and judgment of concrete is required, which increases the complexity and cost of construction and reduces construction efficiency.

[0008] Increased construction safety risks: Misjudged sliding timing may lead to insufficient concrete strength and increase construction safety risks.

[0009] In addition, there is currently no technology and method for using an integrated sliding formwork for the gate well, gate slot and main well lining in special-shaped surge tanks. However, super-large special-shaped surge tanks face many challenges in construction due to their complex structure and huge size, especially the application of sliding formwork construction technology. For super-large surge tanks, the diameter of the surge tank exceeds 30 meters. In the case of huge surge tanks, the template truss beam needs to have a huge bearing capacity. Traditional sliding formwork structures and construction methods are difficult to cope with super-large special-shaped surge tanks. Summary of the invention

[0010] The technical problem to be solved by the present invention is to determine the sliding timing of concrete in extra-large special-shaped shafts through personnel experience, and the purpose is to provide an intelligent determination system and method for the sliding timing of concrete in extra-large special-shaped shafts to solve the above-mentioned problem.

[0011] The present invention is achieved through the following technical solutions:

[0012] In a first aspect, the present invention provides an intelligent determination system for the timing of concrete sliding in an extra-large special-shaped shaft, including a determination module and a sliding detection module;

[0013] The determination module includes a concrete hardening detection unit, a data analysis unit and a control decision unit; the concrete hardening detection unit is used to monitor the degree of hardening of concrete in real time through penetration measurement; the data analysis unit is used to calculate the degree of hardening of concrete through a hardening curve model based on the hardening data of the concrete hardening detection unit, and to determine whether the degree of hardening of concrete meets the requirements; the control decision unit is used to determine the sliding timing of the sliding form based on the hardening degree data of the data analysis unit;

[0014] The sliding detection module is used for sliding formwork and detecting concrete hardening.

[0015] In one possible design, the slip detection module includes a slip form and a penetration detection assembly;

[0016] The penetration detection assembly includes a retractable penetration probe and a first sensor, the penetration probe is used to be inserted into concrete, and the first sensor is used to measure the insertion depth of the penetration probe. Accordingly, the degree of hardening of the concrete is inversely proportional to the insertion depth of the penetration probe.

[0017] A plurality of penetration detection assemblies are provided and distributed on the slipform, and correspondingly, a plurality of penetration detection assemblies constitute a concrete hardening detection unit.

[0018] In a possible design, the penetration detection assembly further includes a plurality of second sensors disposed on the slipform, and the second sensors are used to measure the temperature, humidity, compressive strength, elastic modulus and penetration resistance of the concrete.

[0019] In a possible design, a data transmission unit is further included, and the first sensor and the second sensor both transmit measurement data to the data analysis unit through the data transmission unit.

[0020] In a possible design, the data analysis unit includes a data preprocessing subunit, a hardening model building subunit and a hardening degree analysis subunit;

[0021] The data preprocessing subunit is used to process the received measurement data;

[0022] The hardening model establishment subunit is used to establish a concrete hardening curve model based on the processed data of the data preprocessing subunit;

[0023] The hardening degree analysis subunit is used to determine the hardening degree of concrete based on the hardening curve model.

[0024] In a possible design, the measurement data received by the data preprocessing subunit includes data measured by the first sensor and data measured by the second sensor.

[0025] In one possible design, the control decision unit includes a hardening degree threshold setting subunit and a timing determination subunit;

[0026] The hardening degree threshold setting subunit is used to set the threshold of the concrete hardening degree;

[0027] The timing determination subunit is used to compare the concrete hardening degree determined by the hardening degree analysis subunit with the concrete hardening degree threshold value set by the hardening degree threshold setting subunit, and determine the sliding timing of the sliding form.

[0028] In a second aspect, the present invention provides a method for determining the timing of concrete sliding in a super-large special-shaped shaft based on the intelligent determination system, comprising the following steps:

[0029] S100: several penetration detection components are arranged on the sliding form;

[0030] S200: Detect concrete data through the penetration detection component;

[0031] S300: Combine the construction environment and construction progress and perform data analysis through the determination module;

[0032] S400: Determine the sliding start timing of the sliding mode based on the analysis result of the determination module.

[0033] In one possible design, the determination module performs data analysis by using at least one of a neural network, a decision tree, and a support vector machine.

[0034] In a possible design, when the determination module determines that the concrete hardening reaches a threshold value and the concrete hardening is uniform, the sliding formwork slides up as a whole;

[0035] When the determination module determines that the local hardening of the concrete reaches a threshold value, the sliding form waits for the concrete to harden evenly before sliding up, or adjusts the sliding speed of the sliding form to adapt to the local hardening of the concrete.

[0050] Embodiment 1:

[0051] like Figure 1-Figure 4 As shown, the intelligent judgment system for the timing of concrete sliding in a super-large special-shaped shaft includes a judgment module 10 and a sliding detection module 20;

[0052] The determination module 10 includes a concrete hardening detection unit 1, a data analysis unit 2 and a control decision unit 3; the concrete hardening detection unit 1 is used to monitor the hardening degree of concrete in real time through penetration measurement; the data analysis unit 2 is used to calculate the hardening degree of concrete through a hardening curve model based on the hardening data of the concrete hardening detection unit 1, and to determine whether the hardening degree of concrete meets the requirements; the control decision unit 3 is used to determine the sliding timing of the sliding form 4 based on the hardening degree data of the data analysis unit 2;

[0053] The sliding detection module 20 is used for sliding the sliding formwork 4 and detecting the hardening of concrete.

[0054] The intelligent judgment system for the sliding timing of concrete in super-large special-shaped vertical shafts is used to replace manual work, monitor the degree of concrete hardening in real time, and intelligently judge the sliding timing of the slipform 4, so as to achieve precise control of the sliding timing of the slipform 4, improve the accuracy of the judgment, and eliminate the need for repeated detection and judgment of concrete, thereby reducing the complexity and cost of construction, improving the quality and efficiency of construction, and enhancing the safety of construction.

[0055] At the same time, through the intelligent judgment system for the timing of concrete sliding in super-large special-shaped vertical shafts, the detection, processing, analysis and storage of relevant construction data are realized, and the data management of the construction process is realized. It not only helps to adapt to the construction in various complex environments, but also helps to optimize the construction, improve the efficiency and safety of the construction, and greatly reduce the dependence on manual experience, providing efficient and intelligent construction solutions for the field of construction engineering.

[0056] Specifically, after data detection, collection, analysis and processing, the judgment module 10 accurately gives the sliding timing of the slipform 4, ensures that the degree of concrete hardening meets the construction requirements, avoids construction accidents caused by insufficient concrete strength after the slipform 4 slides, and the slipform 4 slides in time to facilitate the next step of construction, so as to improve the efficiency of construction.

[0057] Among them, the concrete hardening detection unit 1 is used to monitor the hardening of concrete in real time, and transmit the collected relevant hardening data to the data analysis unit 2. Based on the hardening data of the concrete hardening detection unit 1, the data analysis unit 2 performs data analysis and processing, and establishes a hardening curve model for this construction on the basis of the preset concrete hardening model to accurately determine the hardening degree of concrete in this construction. For the control decision unit 3, it uses the hardening degree data of the data analysis unit 2 as the actual value and the set concrete hardening degree as the theoretical value, compares the actual value with the theoretical value, and when the actual value is greater than the theoretical value, the sliding form 4 can be lifted.

[0058] The sliding detection module 20 is the hardware facility of the intelligent judgment system for the sliding timing of the concrete in the super-large special-shaped shaft. When the judgment module 10 issues a sliding command, the sliding detection module 20 starts and slides the sliding form 4. At the same time, the sliding detection module 20 is also used to detect relevant data, cooperate with the concrete hardening unit, enrich the detection range, and provide more data and information for the judgment module 10, so as to comprehensively judge the situation of the concrete and accurately give the timing of the sliding of the sliding form 4.

[0059] During operation, the staff first deploys the sliding detection module 20, then connects the sliding detection module 20 with the determination module 10, and finally starts each functional module. After the concrete is poured, the sliding detection module 20 and the concrete hardening detection unit 1 cooperate with each other to monitor the concrete in real time and collect relevant data. The data analysis unit 2 establishes a relevant model based on the data. The control decision unit 3 determines the sliding timing based on the data of the data analysis unit 2. The sliding detection module 20 slides the sliding formwork 4 in time according to the relevant instructions.

[0060] It is easy to understand that during the operation of the super-large special-shaped shaft concrete sliding timing intelligent judgment system, the staff keeps paying attention to the data of the judgment module 10 to grasp the construction situation and deal with unexpected situations in a timely manner. Accordingly, the super-large special-shaped shaft concrete sliding timing intelligent judgment system also includes a display for displaying data and an input device for use by the staff, and the input device includes but is not limited to a keyboard, a mouse, a control key and a touch device.

[0061] In a possible implementation, the sliding detection module 20 includes a sliding mold 4 and a penetration detection component 5;

[0062] The penetration detection assembly 5 includes a retractable penetration probe 51 and a first sensor 52. The penetration probe 51 is used to be inserted into concrete. The first sensor 52 is used to measure the insertion depth of the penetration probe 51. Accordingly, the degree of hardening of the concrete is inversely proportional to the insertion depth of the penetration probe 51.

[0063] A plurality of penetration detection assemblies 5 are provided and distributed on the slipform 4 , and accordingly, a plurality of penetration detection assemblies 5 constitute a concrete hardening detection unit 1 .

[0064] Based on the above design scheme, the slipform 4 can select any suitable existing model, with a wide range of choices, suitable for different usage scenarios, and better practicality. In the penetration detection component 5, the penetration measurement technology is adopted, and the penetration probe 51 is inserted into the concrete to reflect the hardening condition of the concrete, that is, when the degree of hardening of the concrete increases, the resistance encountered by the penetration probe 51 when inserted into the concrete increases, and the insertion depth decreases, so that the hardening condition of the concrete can be reflected according to the insertion condition of the penetration probe 51; the first sensor 52 is used in conjunction with the penetration probe 51 to accurately detect the insertion depth of the penetration probe 51.

[0065] Specifically, for the penetration detection assembly 5, when working, the number of times and frequency of the penetration probe 51 inserted into the concrete can be preset, or can be temporarily adjusted by the staff, which is more flexible and convenient to use. It is preferred to preset parameters to reduce manual participation and reduce the labor burden of the staff.

[0066] It is easy to understand that the slipform 4 is relatively large in size. In order to accurately reflect the hardening conditions of concrete at various locations of the slipform 4, multiple penetration detection components 5 are provided to measure the concrete at various locations of the slipform 4 respectively, providing good data support for the determination of the determination module 10.

[0067] Furthermore, a plurality of penetration detection components 5 form a concrete hardening detection unit 1, which simplifies hardware facilities and reduces use costs.

[0068] In a possible implementation, the penetration detection assembly 5 further includes a plurality of second sensors disposed on the slipform 4, and the second sensors are used to measure the temperature, humidity, compressive strength, elastic modulus and penetration resistance of the concrete.

[0069] Based on the above design scheme, other data of concrete can be detected by the second sensor, including but not limited to the listed temperature, humidity, compressive strength, elastic modulus and penetration resistance, and any other suitable and relevant data can also be detected, so as to provide the data analysis unit 2 with diverse and sufficient data samples, thereby improving the accuracy of the hardening curve model of the concrete, enabling the control decision unit 3 to accurately determine the sliding timing of the slipform 4, and also helping the staff to grasp the construction progress.

[0070] Optionally, the first sensor 52 and the second sensor are selected from any suitable existing models respectively, with a wide range of choices, adaptable to different usage scenarios, and better practicality.

[0071] In a possible implementation, the (slip detection module 20 ) further includes a data transmission unit, and the first sensor 52 and the second sensor both transmit measurement data to the data analysis unit 2 via the data transmission unit.

[0072] Based on the above design scheme, data transmission is achieved through the data transmission unit. Accordingly, the data sensing unit can select any suitable existing model, with a wide range of choices, adaptable to different usage scenarios, and better practicality.

[0073] In a possible implementation, the data analysis unit 2 includes a data preprocessing subunit 21, a hardening model building subunit 22, and a hardening degree analysis subunit 23;

[0074] The data preprocessing subunit 21 is used to process the received measurement data;

[0075] The hardening model establishment subunit 22 is used to establish a concrete hardening curve model based on the processed data of the data preprocessing subunit 21;

[0076] The hardening degree analysis subunit 23 is used to determine the hardening degree of concrete based on the hardening curve model.

[0077] Based on the above design, in the data analysis unit 2, the data preprocessing subunit 21 is used to receive and preprocess the data obtained from various measurements, so as to facilitate the use of the hardening model establishment subunit 22. The hardening model establishment subunit 22 has any suitable concrete hardening model built in, and establishes a concrete hardening curve model by inputting the processed data of the data preprocessing subunit 21. The hardening degree analysis subunit 23 determines the hardening degree of concrete according to the hardening curve model, that is, obtains the actual value of concrete hardening.

[0078] Therefore, after the sliding detection module 20 obtains the detection data, the data analysis unit 2 obtains the actual value of concrete hardening by processing the data.

[0079] For example, the hardening curve model is updated in time with the insertion of the penetration detection component 5 as the boundary to accurately reflect the hardening of the concrete. On the contrary, if the actual value of the concrete hardening is close to the preset theoretical value, the insertion frequency of the penetration detection component 5 can be increased, and the hardening curve model can be updated in time, thereby assisting the control decision unit 3 to accurately determine the sliding timing of the sliding form 4.

[0080] In a possible implementation, the measurement data received by the data preprocessing subunit 21 includes data measured by the first sensor 52 and data measured by the second sensor. Based on the above design, the data types are rich and the amount of data is large, which helps to improve the accuracy of the hardening curve model. Furthermore, the staff can also use this to analyze the impact of different processes on concrete hardening, optimize the construction, and improve the quality and efficiency of the construction.

[0081] In a possible implementation, the control decision unit 3 includes a hardening degree threshold setting subunit 31 and a timing determination subunit 32;

[0082] The hardening degree threshold setting subunit 31 is used to set the threshold of the hardening degree of concrete;

[0083] The timing determination subunit 32 is used to compare the concrete hardening degree determined by the hardening degree analysis subunit 23 with the concrete hardening degree threshold value set by the hardening degree threshold value setting subunit 31 , and determine the sliding lifting timing of the sliding form 4 .

[0084] Based on the above design scheme, in the control decision unit 3, the staff sets the threshold of the degree of hardening of concrete according to the construction requirements through the hardening degree threshold setting subunit 31, that is, sets the theoretical value. The timing determination subunit 32 is used to compare the actual value with the theoretical value. When the actual value is greater than the theoretical value, it means that the degree of hardening of concrete meets the construction requirements, and the sliding form 4 can be lifted and the next step of construction can be carried out; accordingly, the timing determination subunit 32 can give corresponding instructions to accurately determine the timing of the sliding of the sliding form 4.

[0085] Embodiment 2:

[0086] Based on Example 1, this embodiment introduces a determination method based on the intelligent determination system for the timing of concrete sliding in a super-large special-shaped shaft. The intelligent determination method for the timing of concrete sliding in a super-large special-shaped shaft includes the following steps:

[0087] S100: several penetration detection components 5 are arranged on the sliding form 4;

[0088] S200: Detecting concrete data through the penetration detection component 5;

[0089] S300: combining the construction environment and the construction progress, performing data analysis through the determination module 10;

[0090] S400 : Based on the analysis result of the determination module 10 , determine the sliding lifting timing of the sliding mode 4 .

[0091] Among them, in S100, hardware facilities are prepared and connected to facilitate data monitoring and sliding of the sliding form 4. Further, according to the size of the sliding form 4, a suitable number of penetration detection components 5 and second sensors are selected to ensure complete and thorough coverage of the sliding form 4.

[0092] In S200 , real-time data collection is performed, that is, the first sensor 52 and the second sensor cooperate with each other to collect data related to concrete, so as to be used by the determination module 10 .

[0093] In S300, data processing and analysis, i.e., data processing is performed by the determination module 10 to calculate the concrete strength development in real time. At the same time, based on the data detected in S200, factors such as the construction environment and construction progress are considered to make the sliding timing given by the determination module 10 more suitable for the actual construction situation.

[0094] In S400, the sliding timing is determined by comprehensively considering various factors and based on the data analysis results, intelligently determining whether the concrete has reached the predetermined strength threshold, and determining the optimal sliding timing in combination with the specific construction environment and construction conditions.

[0095] Furthermore, it also includes S500, intelligent feedback and adjustment, which feeds back the judgment results to the staff, who review, adjust and confirm them, and automatically adjust the lifting parameters of the sliding form 4 according to the actual situation to ensure the smooth progress of the concrete sliding process.

[0096] In a possible implementation, the determination module 10 performs data analysis through at least one of a neural network, a decision tree, and a support vector machine. It is easy to understand that any suitable existing algorithm is built into the determination module 10, and data processing, analysis, and determination are performed through the algorithm. Further, in addition to the listed algorithms, the determination module 10 can also be built with any other suitable algorithm.

[0097] In a possible implementation, when the determination module 10 determines that the concrete hardening reaches a threshold value and the concrete hardening is uniform, the sliding form 4 slides up as a whole;

[0098] When the determination module 10 determines that the local hardening of the concrete reaches a threshold value, the sliding form 4 waits for the concrete to harden evenly before sliding up, or adjusts the sliding speed of the sliding form 4 to adapt to the local hardening of the concrete.

[0099] Based on the above design scheme, since the size of the slipform 4 is large, when uneven hardening of concrete occurs, if the construction period permits, the slipform 4 will wait for the concrete to harden evenly before sliding up; if the construction period is tight, the sliding speed of the slipform 4 will be adjusted to maintain support for the concrete and facilitate the next step of construction.

[0100] If the concrete hardens evenly, after the determination module determines that the concrete hardening reaches a threshold, the sliding formwork can be lifted as a whole.

[0101] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

The intelligent determination method for the timing of concrete sliding in a super-large special-shaped vertical shaft according to claim 9 is characterized in that: When the determination module (10) determines that the concrete hardening has reached a threshold value and the concrete hardening is uniform, the sliding form (4) slides upward as a whole; When the determination module (10) determines that the local hardening of the concrete has reached a threshold value, the sliding form (4) waits for the concrete to harden evenly before sliding up, or adjusts the sliding speed of the sliding form (4) to adapt to the local hardening of the concrete.
