Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy and hydropower engineering, and in particular to a leakage early warning system for construction of activated carbon pools in water plants. Background Art

[0002] Activated carbon tanks in water plants are core structures in the water treatment process, primarily used in the advanced treatment stage. Through the activated carbon's adsorption, they remove organic pollutants, odor, color, and some heavy metals from water, improving effluent quality. These tanks typically consist of reinforced concrete tanks filled with granular activated carbon (GAC) or powdered activated carbon (PAC). During operation, they must withstand long-term hydraulic loads, chemical corrosion, and fluctuations in ambient temperature and humidity.

[0003] Pretreatment begins by removing large particles from the raw water through sedimentation and filtration to prevent suspended solids from clogging the activated carbon layer. Appropriate activated carbon is then selected based on the type of pollutant. For example, powdered activated carbon (PAC) is used for emergency treatment or removal of recalcitrant organic matter, while granular activated carbon is suitable for fixed-bed or fluidized-bed adsorption processes. However, monitoring the impermeability of concrete and providing early warning of leakage risks during activated carbon tank construction remains a challenge.

[0004] Chinese patent application publication number: CN109137971A, discloses a construction process for anti-seepage of underground water pools, which adopts precast concrete pile foundation; horizontal reinforcement is added to the opening, protruding parts, and entrances and exits of the structure, and the horizontal reinforcement is tied to the outside of the vertical reinforcement. 18mm thick plywood formwork is used, and anti-seepage concrete is poured. The foundation base plate and the pool wall are poured separately, and the pool wall is poured in two steps. Then a layer of waterproof mortar is applied on the surface of the structure; the construction joint is treated with water-stop steel plates, and the wall sleeve adopts a fixed waterproofing method in which the main pipe is directly buried in the concrete. Finally, after the concrete curing is completed, the water tank is filled with water and a closed water test is carried out.

[0005] It can be seen that the above technical solution relies on traditional structural design and does not consider the impact of water level change rate and infrared thermal image temperature difference on leakage monitoring, resulting in poor construction efficiency. Summary of the Invention

[0006] To this end, the present invention provides a leakage warning system for the construction of activated carbon pools in water plants, which is used to overcome the problem that the existing technology relies on traditional structural design and subsequent water closure tests, and does not consider the impact of water level change rate and infrared thermal image temperature difference on leakage monitoring, resulting in poor construction efficiency.

[0007] To achieve the above objectives, the present invention provides a leakage warning system for the construction of activated carbon pools in water plants, comprising:

[0008] The sample testing module is used to perform an anti-seepage test on the concrete sample and obtain the anti-seepage pressure value and seepage height of the concrete sample;

[0009] A pouring early warning module, used to determine the pouring rate according to the anti-permeability characterization value of the concrete sample;

[0010] A water injection test module, which is connected to the pouring warning module and includes a water level detection unit fixed to the top center of the activated carbon tank via a bracket for monitoring the real-time water level of the activated carbon tank at a preset monitoring period when the tank body is poured to a preset tank wall height and water is injected to a target water level, and an infrared detection unit for obtaining an infrared image of the outer wall of the activated carbon tank;

[0011] A pouring monitoring module, connected to the water injection test module, is used to determine a pouring early warning analysis for the activated carbon pool based on the wetness characterization value of the outer wall of the activated carbon pool, so as to optimize the monitoring period of the pouring of the activated carbon pool according to the water level change rate;

[0012] a leakage warning module for determining a construction joint leakage defect during the construction process of the activated carbon pool based on the determined temperature zone migration of the low temperature zone of the corresponding monitoring period;

[0013] A defect response module is connected to the leakage warning module, and determines to adjust the construction parameters of the subsequent activated carbon pool construction process based on the defect form of the activated carbon pool construction process.

[0014] Furthermore, the leakage warning module determines based on the temperature zone migration of the low temperature zone,

[0015] One of the temperature zone migration range values ​​represents the concrete density defect;

[0016] Another temperature zone migration range value represents the construction joint leakage defect.

[0017] Furthermore, the temperature region is constructed based on a minimum temperature region contour obtained by sequentially connecting minimum isothermal points in an infrared image of one of the preset low temperature regions;

[0018] Wherein, the low temperature zone is determined based on a first preset temperature.

[0019] Furthermore, the temperature region migration is characterized based on the difference between the maximum width values ​​on the minimum temperature region profiles of two adjacent monitoring periods, wherein:

[0020] Temperature zone migration to predict defect forms based on temperature flow distribution.

[0021] Furthermore, the pouring warning module determines the leakage risk level of the concrete used for the construction of the activated carbon pool of the water plant in sequence according to the anti-seepage characterization value of the concrete sample and several preset anti-seepage characterization values; the anti-seepage characterization value is determined by the anti-seepage water pressure value and seepage height of the concrete sample obtained in the anti-seepage test.

[0022] Furthermore, the pouring warning module is used to, when the leakage risk level is the second leakage risk level, first pour at a first preset pouring rate for a preset time, and then switch to a second preset pouring rate to pour the pool body to a preset pool wall height;

[0023] Wherein, the first preset pouring rate is less than the second preset pouring rate.

[0024] Furthermore, the pouring monitoring module reduces the monitoring period in response to the wetness characterization value being greater than or equal to a first preset wetness characterization value and less than a second preset wetness characterization value and the water level change rate being greater than or equal to a preset water level change rate.

[0025] Furthermore, the reduction amplitude of the monitoring period is positively correlated with the water level change difference, wherein the water level change difference is the difference between the water level change rate and the preset water level change rate.

[0026] Furthermore, the defect response module increases the vibration time of subsequent tank construction in response to the concrete compaction defect.

[0027] Furthermore, the defect response module increases the roughening depth of the construction joint surface in subsequent tank body construction in response to the construction joint leakage defect.

[0028] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention comprehensively evaluates the performance of concrete materials based on the anti-seepage pressure value and seepage height of the concrete sample, divides the leakage risk into four levels and matches the corresponding pouring strategy, thereby realizing precise control of the construction pouring rate and avoiding the leakage risk caused by fixed-rate pouring; obtains the temperature field distribution of the outer wall of the pool body through infrared thermal imaging technology to obtain the wetness characterization value; verifies the construction effect of the activated carbon pool through the wetness characterization value; and uses the temperature difference in the low temperature zone to determine the leakage type, thereby improving the construction efficiency of the activated carbon pool.

[0029] Furthermore, the present invention accurately quantifies the risk level based on the comparison between the anti-seepage characterization value and the preset threshold value, and dynamically controls the construction according to the comparison between the anti-seepage characterization value and the preset threshold value, thereby reducing the leakage risk during the concrete pouring process and improving the efficiency of concrete construction.

[0030] Furthermore, the present invention obtains an anti-seepage characterization value through the anti-seepage water pressure value and seepage height of the concrete sample obtained in the anti-seepage test, converts the microscopic properties of concrete such as the pore structure and density into measurable engineering indicators, makes the anti-seepage performance of concrete intuitive, and realizes the prediction of the anti-seepage performance of concrete before concrete construction, thereby achieving precise control of concrete construction.

[0031] Further, the present application realizes non-contact preliminary screening of leakage risk by analyzing the area proportion of the low temperature area of the outer wall of the activated carbon pool through infrared image analysis to obtain a wetness characterization value, and when the wetness characterization value is between the first threshold value and the second threshold value, secondary judgment is performed through the water level change rate to avoid misjudgment of a single parameter, thereby improving the evaluation reliability.

[0032] Further, the present application realizes precise control of the reduction range of the monitoring period by setting the reduction range of the monitoring period in positive correlation with the water level change difference.

[0033] Further, the present application establishes a mapping relationship between defect types and temperature migration by differentiating the temperature area migration range value, so that the determination of concrete compactness defects and construction joint leakage defects has a quantifiable standard, and improper repair measures caused by defect misjudgment are avoided, thereby improving the accuracy of leakage defect diagnosis.

[0044] An embodiment of the present invention provides a leakage warning system for construction of activated carbon pools in water plants, comprising:

[0045] The sample testing module is used to perform an anti-seepage test on the concrete sample and obtain the anti-seepage pressure value and seepage height of the concrete sample;

[0046] A pouring early warning module, used to determine the pouring rate according to the anti-permeability characterization value of the concrete sample;

[0047] A water injection test module, which is connected to the pouring warning module, includes a water level detection unit 3 fixed to the top center of the activated carbon tank 1 by a bracket 2 for monitoring the real-time water level of the activated carbon tank at a preset monitoring period under the conditions that the tank body 1 is poured to a preset tank wall height and water is injected to a target water level, and an infrared detection unit for obtaining an infrared image of the outer wall of the activated carbon tank;

[0048] A pouring monitoring module, connected to the water injection test module, is used to determine a pouring early warning analysis for the activated carbon pool based on the wetness characterization value of the outer wall of the activated carbon pool, so as to optimize the monitoring period of the pouring of the activated carbon pool according to the water level change rate;

[0049] a leakage warning module connected to the pouring monitoring module, which determines the construction joint leakage defect during the construction process of the activated carbon pool based on the temperature zone migration of the low temperature zone in the corresponding monitoring period;

[0050] A defect response module is connected to the leakage warning module, and determines to adjust the construction parameters of the subsequent activated carbon pool construction process based on the defect form of the activated carbon pool construction process.

[0051] Specifically, the preset pool wall height is 50%-80% of the total designed pool wall height. In this embodiment, the preset pool wall height is selected as 50% of the total designed pool wall height.

[0052] Specifically, the height of the target water level is 90% of the preset pool wall height of the activated carbon pool.

[0053] Specifically, the water level detection unit 3 is a high-frequency radar level gauge.

[0054] There is no limitation on the specific structure of the pouring warning module, pouring monitoring module, leakage warning module and defect response module. They themselves and each unit therein can be composed of logic components, which include field programmable components, computers or microprocessors in computers.

[0055] Specifically, the concrete sample is a truncated cone with a preset top diameter of 175 mm, a preset bottom diameter of 185 mm, and a preset height of 150 mm.

[0056] Specifically, the concrete sample is subjected to an anti-permeability test to obtain the water seepage height of the concrete sample and the anti-permeability pressure value of the concrete sample; specifically, the concrete sample is placed in an anti-permeability tester, starting from 0.1 MPa, and increasing by 0.1 MPa every 8 hours until water seeps out from the top surface of the sample or the pressure is increased to a maximum water pressure of 2 MPa and still no water seeps out from the top surface of the sample;

[0057] When water seeps out from the top surface of the sample, record the current seepage water pressure value as the anti-seepage water pressure value of the concrete sample, and record the preset height of the concrete sample as the seepage height of the concrete sample;

[0058] When no water seeps out from the top surface of the specimen even after the pressure is increased to the maximum water pressure of 2 MPa, split the concrete specimen along its axis and measure the water seepage height at 10 equally divided points with a steel ruler. The average of the water seepage heights at the 10 equally divided points is calculated and recorded as the water seepage height of the concrete specimen. The maximum water pressure of 2 MPa is recorded as the anti-water seepage pressure value of the concrete specimen.

[0059] Specifically, the pouring warning module determines the leakage risk level of the concrete used for the construction of the activated carbon pool of the water plant according to the anti-seepage characterization value of the concrete sample, wherein:

[0060] If the anti-seepage characterization value is less than the first preset anti-seepage characterization value of 0.125, the leakage risk level of the concrete used for the construction of the activated carbon pool of the water plant is determined to be the first leakage risk level;

[0061] If the anti-seepage characterization value is greater than or equal to the first preset anti-seepage characterization value and less than the second preset anti-seepage characterization value of 0.25, the leakage risk level of the concrete used for construction of the activated carbon pool of the water plant is determined to be the second leakage risk level;

[0062] If the anti-seepage characterization value is greater than or equal to the second preset anti-seepage characterization value and less than the third preset anti-seepage characterization value of 0.52, the leakage risk level of the concrete used for construction of the activated carbon tank of the water plant is determined to be the third leakage risk level;

[0063] If the anti-seepage characterization value is greater than or equal to the third preset anti-seepage characterization value, the leakage risk level of the concrete used for the construction of the activated carbon pool of the water plant is determined to be the fourth leakage risk level.

[0064] Specifically, the first preset anti-seepage characterization value is 0.125, the second preset anti-seepage characterization value is 0.25, and the third preset anti-seepage characterization value is 0.52, but the above values ​​are not limited to this. Those skilled in the art can also adjust the values ​​according to actual needs.

[0065] In this embodiment, the anti-seepage characterization value is calculated by the following formula:

[0066]

[0067] Where K represents the anti-seepage characterization value; P represents the anti-seepage pressure value of the concrete sample; P0 represents the maximum anti-seepage pressure value of the concrete sample, and P0 is set to 2 MPa; h represents the seepage height of the concrete sample; h0 represents the preset height of the concrete sample, and h0 is set to 150 mm.

[0068] The water pressure value (P) measures the concrete's ability to resist water penetration under pressure. The higher the P value, the greater the concrete's ability to prevent water from penetrating under high pressure, and the better its overall water resistance.

[0069] The water seepage height h reflects the degree of water penetration into the concrete. The smaller the h value, the shorter and more discontinuous the water penetration channel is, and the better the internal density of the concrete.

[0070] The larger the anti-seepage characterization value, the better the overall anti-seepage performance; the smaller the anti-seepage characterization value, the higher the leakage risk.

[0071] Specifically, the pouring warning module determines the corresponding strategy according to the leakage risk level, wherein:

[0072] If the leakage risk level is the first leakage risk level, suspending the pouring of the activated carbon pool and issuing a repair warning;

[0073] If the leakage risk level is the second leakage risk level, first use the first preset pouring rate of 0.6m 3 / h pouring preset time is 2h, then switch to the second preset pouring rate of 1.3m 3 / h to complete the pouring of the activated carbon pool;

[0074] If the leakage risk level is the third leakage risk level, the second preset pouring rate is 1.3m 3 / hComplete pouring and add waterproofing agent;

[0075] If the leakage risk level is the fourth leakage risk level, pouring is completed at the second preset pouring rate;

[0076] Wherein, the first preset pouring rate is less than the second preset pouring rate.

[0077] In this embodiment, the selection range of the first preset pouring rate is (0.5m 3 / h, 0.8m 3 / h), the selection range of the second preset pouring rate is (1.2m 3 / h, 1.5m 3 / h), preferably, the first preset pouring rate is selected as 0.6m 3 / h, the second preset pouring rate is selected as 1.3m 3 / h.

[0078] In this embodiment, the waterproofing agent can be selected from polypropylene fiber or calcium formate, without specific limitation, as long as it meets the pouring construction requirements.

[0079] The pouring monitoring module determines whether the construction of the activated carbon pool meets the preset standards based on the wetness characterization value of the outer wall of the activated carbon pool, wherein:

[0080] If the wetness characterization value is less than the first preset wetness characterization value of 0.35, it is determined that the construction of the activated carbon pool meets the preset standard;

[0081] If the wetness characterization value is greater than or equal to the first preset wetness characterization value and less than the second preset wetness characterization value of 0.65, it is determined that the construction of the activated carbon pool does not meet the preset standard, and a second determination is made based on the water level change rate whether the construction of the activated carbon pool meets the preset standard;

[0082] If the wetness characterization value is greater than or equal to the second preset wetness characterization value, it is determined that the construction of the activated carbon pool does not meet the preset standard, and the leakage warning module determines the defect form of the construction process of the activated carbon pool according to the temperature zone migration of the low temperature zone.

[0083] Specifically, the first preset wetness characterization value is selected in the range of (0.20, 0.40), and the second preset wetness characterization value is selected in the range of (0.55, 0.85). Preferably, the first preset wetness characterization value is selected as 0.35, and the second preset wetness characterization value is selected as 0.65.

[0084] Specifically, the wetness characterization value of the outer wall of the activated carbon pool is the ratio of the area of ​​the low temperature area to the total area in the infrared image of the infrared detection unit.

[0085] Specifically, the infrared detection unit is a thermal imager to obtain infrared images.

[0086] In this embodiment, the area of ​​the region in the infrared image is obtained by IMAGEPro software.

[0087] Specifically, the leakage warning module determines whether the construction of the activated carbon pool meets the preset standards based on the water level change rate.

[0088] If the water level change rate is less than the preset water level change rate of 4 mm / d, it is determined that the construction of the activated carbon pool meets the preset standards;

[0089] If the water level change rate is greater than or equal to the preset water level change rate, it is determined that the construction of the activated carbon pool does not meet the preset standard, a leakage warning is issued, and the monitoring period is reduced according to the difference between the water level change rate and the preset water level change rate;

[0090] The water level change rate is the water level change rate within a preset monitoring period of 24 hours.

[0091] Specifically, the water level value is obtained through a high-frequency radar level meter.

[0092] Specifically, the reduction amplitude of the monitoring period is positively correlated with the water level change difference, wherein the positive correlation is, for example, a linear positive correlation or a nonlinear positive correlation, and the linear slope of the linear positive correlation is not specifically limited. It can be understood that the greater the water level change difference, the greater the reduction amplitude of the monitoring period; the water level change difference is the difference between the water level change rate and the preset water level change rate.

[0093] Specifically, the leakage warning module is determined according to the temperature zone migration of the low temperature zone, wherein:

[0094] If the temperature zone migration value is within the first preset temperature zone migration range, it is determined that there is a concrete density defect;

[0095] If the temperature zone migration value is within the second preset temperature zone migration range, it is determined that there is a construction joint leakage defect;

[0096] The migration range of the first preset temperature region is (0, 15 mm), and the migration range of the second preset temperature region is (20 mm, 50 mm).

[0097] Specifically, the temperature region is constructed based on the minimum temperature region contour obtained by sequentially connecting the minimum isothermal points in the infrared image of one of the preset low temperature regions;

[0098] The low temperature zone is determined based on a first preset temperature of 23°C.

[0099] In this embodiment, the first preset temperature is selected as 23° C., but the above value is not limited thereto, and those skilled in the art may also adjust the value according to actual needs.

[0100] Specifically, the temperature region migration is characterized based on the difference in maximum width values ​​on the minimum temperature region profile between two adjacent monitoring periods, wherein:

[0101] Temperature zone migration to predict defect forms based on temperature flow distribution.

[0102] Specifically, concrete density defects usually manifest as local non-dense areas such as honeycombs, holes, and bubble aggregations, and the leakage paths are mostly dispersed pore networks; water penetration forms a relatively uniform diffusion in the defective area due to the strong randomness of pore distribution, and the expansion direction corresponding to the low temperature area is relatively chaotic, and the overall contour changes little.

[0103] Specifically, the construction joint leakage defect is as follows: the construction joint is a linear structure, and the leakage path is distributed in a long strip along the direction of the joint. When water penetrates along the construction joint interface, it is easy to form a continuous linear channel. The low temperature area extends along the length of the joint, forming a "long strip" temperature distribution. Since the leakage expands along the linear direction, the maximum width of the contour of the adjacent period increases significantly.

[0104] Specifically, the minimum temperature area outline and the maximum width value of the minimum temperature area outline in the infrared image are obtained through thermal imaging software.

[0105] Specifically, the defect response module increases the vibration time of the subsequent tank body 1 construction in response to the concrete compaction defect.

[0106] In this embodiment, the maximum vibration time of the subsequent pool body 1 construction is increased to 30 seconds, which is not specifically limited. Those skilled in the art can also adjust the increased vibration time according to actual needs.

[0107] Specifically, the defect response module increases the roughening depth of the construction joint surface in subsequent construction of the pool body 1 in response to the construction joint leakage defect.

[0108] In this embodiment, the maximum roughening depth of the construction joint surface of the subsequent pool body 1 construction is increased to 10 mm, which is not specifically limited. Those skilled in the art can also adjust the increased vibration time according to actual needs.

[0109] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.

[0110] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
