[0002] Many modern buildings are constructed of reinforced concrete. Over time, and due to the inevitable effects of fire and erosion, concrete structures are susceptible to damage. When concrete structures are damaged, especially by acid rain or intense heat from fire, the capillary pores in the components increase, the alkaline environment within the concrete is destroyed, and the internal steel reinforcement loses the concrete's protection, eventually corroding and causing damage. Given the complexity and sheer size of these structures, demolishing and rebuilding damaged concrete structures is not feasible. Therefore, from both an economical and environmental perspective, measures to repair damaged concrete components are necessary.

[0003] Existing repair technologies mostly involve replacing the damaged surface concrete or using water's electrochemical reaction to repassivate the steel.

DETAILED DESCRIPTION

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail with reference to the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. The technical solutions of the present invention will be described in detail below with reference to the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0037] Reference Figure 1-10 This embodiment takes the single-sided fire repair of a concrete column as an example and proposes an intelligent device for repairing and self-repairing damaged concrete suitable for various occasions, including a connecting plate 100, a working plate 200, a hoop 301, and a working platform 400.

[0038] For details on the structure of the connecting plate 100, please refer to Figure 2-Figure 4 The connecting plate 100 is an L-shaped structural plate with a top plate and a bottom plate. The side edges of the bottom plate of the connecting plate 100 are provided with shoulder tenons 105 and shoulder tenons 106. The four connecting plates 100 are connected by the shoulder tenons 105 and shoulder tenons 106 between the bottom plates. Connection ports 101 are provided on both sides of the top plate of the connecting plate 100. The connection ports 101 are provided with a row of first circular tenons 107. Waterproofing pads 102 are provided between the two side connection ports 101. The top plate of the connecting plate 100 is located at the bottom of the working plate 200 and is connected to the two rows of circular tenons 206 provided at the bottom of the working plate 200 via the connection ports 101. This allows the connecting plate 100 to be tightly fixed to the bottom of the concrete column to be repaired. The connecting plates 100 are tightly fixed with bolts to provide waterproofing and water isolation.

[0039] like Figure 5 and Figure 6 As shown, the work panels 200 are made of a material with a certain degree of elasticity, such as a polymer resin board. The lower edge of the lowest work panel 200 is provided with a dovetail 206 for connecting to the top plate of the connecting plate 100. The upper edge of the work panel 200 may also be provided with a second dovetail groove 207 that receives the dovetail 206. This allows the work panels 200 to be spliced upwards according to the height of the concrete column. The left and right edges of the work panel 200 are respectively provided with dovetail tenons 204 and dovetail grooves. The four work panels 200 on the same level are connected by dovetail tenons 204 and dovetail grooves. If the damaged area of the concrete component is large, the dovetail tenons 204 on the work panel 200 can be used for longitudinal splicing, while the longitudinal dovetail tenons 206 on the work panel 200 can be used for longitudinal splicing. A fluid infusion bag 208 is connected to the inner side of a work plate 200 adjacent to the damaged area of the concrete component to be repaired. A stainless steel mesh 211 is attached to the inner side of the bag 208. The stainless steel mesh 211, attached to one side of the damaged area, serves as an anode for electrochemical realkalinization of the concrete. A piezoelectric ceramic sheet 212 with a vacuum suction cup is secured to the stainless steel mesh 211. A first valve port 205 is provided on the work plate 200 adjacent to the damaged area of the concrete component to be repaired. This first valve port 205 is connected to the fluid infusion bag 208 via a main fluid infusion pipe 209. The infusion bag 208 is connected to the damaged area of the concrete component to be repaired via multiple auxiliary fluid infusion pipes 210, utilizing the dripping principle to conserve fluid. Electrolyte solutions, microorganisms, and culture media can be delivered to the damaged area at multiple points via the first valve port 205, main fluid infusion pipe 209, bag 208, and auxiliary fluid infusion pipes 210.

[0040] In this embodiment, if only one side of the concrete column requires repair, the inner side of the work panel 200 adjacent to that side is equipped with an infusion airbag 208, a stainless steel mesh 211, and a piezoelectric ceramic sheet 212 with a vacuum chuck. The inner sides of the work panel 200 on the other three sides do not need to be equipped with an infusion airbag 208, a stainless steel mesh 211, and a piezoelectric ceramic sheet 212 with a vacuum chuck. If multiple sides require repair, the inner sides of the corresponding work panels 200 must all be equipped with an infusion airbag 208, a stainless steel mesh 211, and a piezoelectric ceramic sheet 212 with a vacuum chuck. Adjacent stainless steel meshes 211 are connected by steel structures 213 installed on the sides.

[0041] The side interfaces between the connected working panels 200 are fixed to the waterproof connection ports 203 provided on the working panels 200 via waterproof connection angle steels 306, further reinforcing the waterproof connection and preventing water from leaking through the gaps. The hoop 301 is then placed tightly against the four sides of the working panels 200, and bolts 305 are passed through the reserved holes 202 on the working panels 200, connecting the reserved holes 302 and the hoop 301 to further tighten the hoop. Figure 7 and Figure 8 The hoop 301 is composed of multiple hoop unit pieces 303 connected end to end by a pin shaft. It is a bendable structure to ensure that the hoop can be deformed while having a certain rigidity; the hoop unit piece 303 is provided with a hoop reserved hole 302, and the hoop reserved hole 302 is used to fix the hoop 301 on the working plate 200. In addition, the hoop reserved hole 302 and the reserved hole 202 on the working plate 200 corresponding to the hoop reserved hole 302 can be connected to an injection tube 304 for injecting microorganisms or other substances into the damaged concrete.

[0042] See also Figure 1 The workbench 400 is equipped with an electrolyte storage tank 401, a microorganism culture tank 402, a computer 405, an external power supply port 406, a motor 407, and a pump 408. The external power supply port 406 is connected to the motor 407 via a wire 410. The motor 407 is connected to the pump 408 and the computer 405, respectively, to provide electrical energy to both. The pump 408 is connected to the electrolyte storage tank 401 and the microorganism culture tank 402 via a pipe 409. The electrolyte storage tank 401 and the microorganism culture tank 402 are each equipped with a second valve port 403, which is connected to the first valve port 205 via a pipeline. The piezoelectric ceramic sheet 212 with a vacuum suction cup is connected to the data acquisition channel 404 on the computer 405 via a wire.

[0043] The specific working process is:

[0044] After the connection is completed, the computer 405 is started, and the piezoelectric ceramic sheet 212 with a vacuum suction cup on the working plate 200 close to one side of the component to be repaired is adsorbed on the damaged part, and the piezoelectric ceramic sheet 212 with a vacuum suction cup is started.

[0045] The concrete electrochemical re-alkalization process is started to repair the alkaline environment of the concrete. First, the second valve port 403 on the electrolyte storage tank 401 is opened, and the second valve port 403 on the microorganism culture tank 402 is closed; 1mol / LNa2CO3 electrolyte is delivered to the first valve port 205. The electrolyte will first gradually fill the infusion airbag 208 through the infusion main pipe 209, and then fill the space between the working plate 200 and the component through the infusion auxiliary pipe 210 and penetrate into the concrete using the infiltration principle. At this time, the piezoelectric ceramic sheet 212 with a vacuum suction cup starts to work. As the electrolyte liquid gradually penetrates into the concrete component, the piezoelectric signal will show different changes. The signal is input into the computer 405 and software such as MATLAB is used to press Figure 9 The program is processed. When the system terminates the program, it can be considered that both the anode and the cathode are immersed in the electrolyte. When the workbench 200 is connected to the power supply, in order to avoid electrolysis of water, the current should be 0.1A-1A DC. The steel bar in the concrete component is connected to the positive pole of the power supply as the cathode to conduct H2O+0.5O 2 +2e=2OH - The stainless steel mesh 211 is used as the anode to react with 2OH - =H2O+0.5O 2 +2e reaction.

[0046] About a week after the repair, loosen the pipe 409 and the second valve port 403 on the electrolyte storage tank 401 to drain the electrolyte liquid. Keep all working plates 200 connected to the connection port 101 so that the working plates 200 are in close contact with the damaged components. Install the injection tube 304 on the hoop reserved hole 302. Close the second valve port 403 on the electrolyte storage tank 401 and open the second valve port 403 of the microbial culture tank 402. Use the pump 408 to transport microbial culture liquid and anaerobic microorganisms into the working plate 200. As the microorganisms induce calcium carbonate deposition, the piezoelectric signal undergoes new changes. The signal is input into the computer 405 and pressed. Figure 10 The anaerobic microorganisms and culture medium will appear on the cracks of concrete after fire along with the residual electrolyte in the concrete. In the transported culture medium, anaerobic microorganisms hydrolyze urea through urease to form calcium carbonate precipitation. Urea is finally hydrolyzed into ammonia and carbonic acid through a series of metabolic reactions of enzymes in the cells, accompanied by the shift of carbonate balance (CO 2 to HCO 3 and CO 2- ), calcium ions in the concrete medium react with carbonate ions to form insoluble calcium carbonate CaCO on the cell surface 3The sediment heals the cracks, achieving repair. Furthermore, during this process, aerobic microorganisms are injected into the damaged component through an injection tube 304 fixed to the hoop. The aerobic microorganisms injected into the concrete become dormant in the anaerobic environment and then, when the concrete cracks again, the spores regenerate and repair the concrete, achieving the goal of self-repair. The anaerobic microorganisms are Shewanella, and the aerobic microorganisms are Bacillus pseudofirmus and Bacillus cohnii. The bacteria are encapsulated in expanded clay particles to prolong their life in the alkaline environment. Both anaerobic and aerobic microorganisms are commercial strains purchased from the market.

[0047] Principle 1 of the present invention: Concrete electrochemical realkalinization method: On the steel bar (cathode): H2O+0.5O 2 +2e=2OH - On the external electrode (anode): 2OH - =H2O+0.5O 2 +2e, under the action of the electric field, the cathode reaction product OH inside the concrete - The external cation Na migrates from the steel bar through the protective layer to the concrete surface. + , K + and Ca 2+ Migrate from the anode to the cathode. During this migration process, the alkaline electrolyte will quickly penetrate into the concrete, increasing the pH value of the carbonized concrete.

[0048] Principle 2 of the present invention: Use anaerobic microorganisms to repair concrete. Anaerobic microorganisms hydrolyze urea through urease to form calcium carbonate precipitation. Urea is finally hydrolyzed into ammonia and carbonic acid through a series of metabolic reactions of enzymes in the cell, accompanied by the shift of carbonate balance (CO2 to HCO3 and CO 2- ), the calcium ions in the concrete medium react with carbonate ions to form insoluble calcium carbonate (CaCO3) deposits on the cell surface to heal the cracks and achieve the purpose of repair.

[0049] Principle 3 of the present invention: Aerobic microorganisms injected into the concrete become dormant as spores in an anaerobic environment. When the concrete cracks again later, the spores revive and repair the concrete, thereby achieving the purpose of concrete self-repair.

[0050] The vacuum sheet on the outside of the piezoelectric ceramic sheet 212 with a vacuum suction cup isolates moisture and fixes the internal piezoelectric ceramic sheet to the concrete surface; the piezoelectric effect of the piezoelectric ceramic in different media is used for detection, and the detection information includes: the piezoelectric signal during the process of continuous injection of electrolyte liquid into the damaged concrete; the piezoelectric signal of the process of continuous generation of calcium carbonate when microorganisms repair concrete components.

[0051] By analyzing the piezoelectric signal during the continuous injection of the electrolyte liquid by a computer, the degree of immersion of the electrolyte liquid in the damaged concrete can be obtained, which to a certain extent reflects the degree of recovery of the alkaline environment of the concrete and controls whether the host continues to supply the electrolyte liquid.

[0052] By analyzing the piezoelectric signal of the continuous production of calcium carbonate during microbial repair by computer, the degree of repair of the damaged concrete can be obtained, and the host can be controlled to continue supplying microorganisms based on the analysis results.

[0053] The computer workbench has multiple working channels, which can process multiple piezoelectric signals at the same time to realize simultaneous detection and repair of multiple components; the workbench is connected to a pump machine, which can supply repair materials according to the processing results of the piezoelectric signals.

[0054] The above content is a further detailed description of the present invention in combination with a specific preferred embodiment. It cannot be considered that the specific embodiments of the present invention are limited to this. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the present invention, which should be regarded as belonging to the scope of patent protection determined by the submitted claims of the present invention.
