Description

Technical Field

[0001] This application belongs to the field of reinforced concrete crushing technology, specifically relating to a method for crushing reinforced concrete by using shock waves generated by electrical explosion. Background Technology

[0002] Reinforced concrete is a composite material made by adding steel mesh, steel cages, or steel plates to concrete. The addition of steel significantly improves the mechanical properties of concrete. The steel bars bear tensile forces, while the concrete bears compressive forces. Reinforced concrete structures are strong, durable, fire-resistant, and more cost-effective than steel structures, saving on steel. Therefore, reinforced concrete structures are widely used in urban construction. When demolishing reinforced concrete structures, methods typically include blasting, mechanical demolition, and manual removal. Blasting is faster but poses a high environmental hazard and is strictly limited in urban areas. Mechanical demolition and manual removal have less environmental impact, but suffer from low demolition efficiency and a high risk of injury to workers. Therefore, existing methods for demolishing reinforced concrete structures do not meet current needs. Summary of the Invention

[0003] This application provides a method for breaking reinforced concrete by using an electric explosion to generate a shock wave, which solves the problem of high risk in the prior art of demolishing reinforced concrete structures by blasting.

[0004] To achieve the above objectives, embodiments of the present invention provide a method for breaking reinforced concrete using shock waves generated by electrical explosions, comprising the following steps:

[0005] A shock wave operation point group is set up on a reinforced concrete structure. The shock wave operation point group includes one high-voltage operation point and one or more low-voltage operation points. The distance between the high-voltage operation point and the low-voltage operation point is less than a set distance.

[0006] A liquid storage chamber is constructed at the high-voltage operation point and the low-voltage operation point respectively, and then the electrolyte is injected into the liquid storage chamber so that the electrolyte comes into contact with the reinforced concrete structure;

[0007] A high-voltage electrode is arranged so that it contacts the electrolyte at the high-voltage working point; a low-voltage electrode is arranged so that it contacts the electrolyte at the low-voltage working point.

[0008] The end of the high-voltage electrode is connected to the high-voltage terminal of the pulse power source, and the end of the low-voltage electrode is connected to the low-voltage terminal of the pulse power source.

[0009] The pulsed power source generates a high voltage and a large current to discharge to the high voltage electrode and the low voltage electrode. A high voltage arc and partial discharge are generated between the high voltage electrode and the low voltage electrode, penetrating the reinforced concrete structure. The pulsed strong electric field is conducted through the steel bars in the reinforced concrete structure to penetrate deep into the interior of the reinforced concrete structure, so as to maximize the feeding of electrical energy into the interior of the reinforced concrete structure, and finally generate a shock wave that causes the concrete to break.

[0010] In one possible implementation, when constructing the liquid storage chamber, working holes are drilled and / or external electrode assemblies are arranged in the reinforced concrete structure;

[0011] The working hole is the liquid storage cavity; the suction cup of the external electrode assembly and the outer wall of the reinforced concrete structure form the liquid storage cavity.

[0012] In one possible implementation, after drilling the working hole, the electrode rod is placed into the working hole, so that the electrode post at the lower end of the electrode rod is located at the set working point. The high-voltage electrode or the low-voltage electrode is connected to the cable connector cap at the upper end of the electrode rod, and the cable connector cap is connected to the electrode post through a high-voltage center rod.

[0013] Then, the electrolyte is injected into the working hole to bring the electrode post into contact with the electrolyte.

[0014] In one possible implementation, when the working hole is a horizontal drill hole or an upward drill hole, an orifice sealing device is installed at the orifice of the working hole.

[0015] In one possible implementation, the depth of the working hole is less than or equal to 60 cm.

[0016] In one possible implementation, when arranging the external electrode assembly, the suction cup of the external electrode assembly is attached to the reinforced concrete structure, and the output electrode of the external electrode assembly is connected to the high-voltage electrode or the low-voltage electrode.

[0017] The electrolyte is injected into the storage chamber through the water inlet pipe on the suction cup, so that the output electrode comes into contact with the electrolyte.

[0018] In one possible implementation, before attaching the suction cup of the external electrode assembly to the reinforced concrete structure, grease is applied to the end face of the mating ring of the suction cup, and the grease comes into contact with the reinforced concrete structure.

[0019] In one possible implementation, the pulsed power source generates a high voltage and high current by including the following steps:

[0020] The high-voltage capacitor of the pulse power source is charged by the power supply. After the high-voltage capacitor is charged to the working voltage, the gas spark switch is triggered to close, causing the high-voltage capacitor to discharge rapidly and generate a high voltage and large current.

[0021] In one possible implementation, the set distance is 60cm.

[0022] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0023] This invention provides a method for breaking reinforced concrete using shock waves generated by an electrical explosion. The method involves forming a discharge circuit between a high-voltage electrode and a low-voltage electrode, with multiple discharge circuits formed between a high-voltage working point and multiple low-voltage working points. A high-voltage arc and partial discharge are generated between the high-voltage and low-voltage electrodes, penetrating the reinforced concrete structure. At the instant the high-voltage arc is generated, the air surrounding the arc is rapidly heated and expands, generating a shock wave that breaks the concrete. Furthermore, shorter arcs generated by partial discharges between the high-voltage and low-voltage electrodes also produce shock waves that act on the concrete. During this process, although the brine does not directly contact the reinforcing steel of the reinforced concrete structure, the system utilizes the basic principle of adjusting the electric field distribution through isolated conductors in the medium. The pulsed strong electric field is conducted through the reinforcing steel to penetrate deep into the reinforced concrete structure, maximizing the input of electrical energy into the interior, thereby achieving the purpose of breaking the concrete through an electrical explosion. A small-scale arc is formed near the arc-shaped region of the high-voltage electrode, and a breakdown channel gradually forms from the high-voltage electrode into the interior of the reinforced concrete structure. During the extension of the breakdown channel within the concrete, the extension speed of the channel inside the concrete is greater than the speed at which surface discharge forms. Ultimately, a breakdown channel forms first inside the concrete, at which point the breakdown process is complete, and a plasma channel is formed. This plasma channel then rapidly expands, generating a powerful shock wave that causes the concrete to break. When the distance between the high-voltage and low-voltage electrodes is greater than a set distance, the distance for surface discharge becomes shorter, which may cause the surface discharge process to develop faster than the internal discharge process. This results in a discharge channel forming first on the concrete surface, leading to the inability to generate an effective shock wave. Therefore, keeping the distance between the high-voltage and low-voltage operating points less than a set distance ensures the smooth implementation of the electro-explosive breaking process. The system of this invention has high efficiency and safety in breaking reinforced concrete structures, and low labor intensity for operators, making it highly practical and easy to promote.

[0034] like Figures 1 to 6 As shown in the figure, the method for breaking reinforced concrete using shock waves generated by electrical explosion provided in this embodiment of the invention includes the following steps:

[0035] A shock wave operation point group is set up on the reinforced concrete structure 1. The shock wave operation point group includes one high-voltage operation point 2 and one or more low-voltage operation points 3. The distance between the high-voltage operation point 2 and the low-voltage operation point 3 is less than a predetermined distance.

[0036] A liquid storage chamber 4 is constructed at both the high-voltage operation point 2 and the low-voltage operation point 3. Then, the electrolyte is injected into the liquid storage chamber 4 so that the electrolyte comes into contact with the reinforced concrete structure 1.

[0037] Arrange high-voltage electrode 5 so that it comes into contact with the electrolyte at high-voltage operating point 2. Arrange low-voltage electrode 6 so that it comes into contact with the electrolyte at low-voltage operating point 3.

[0038] Connect the end of the high-voltage electrode 5 to the high-voltage electrode end of the pulse power source 7, and connect the end of the low-voltage electrode 6 to the low-voltage electrode end of the pulse power source 7.

[0039] The pulsed power source 7 generates a high voltage and high current to discharge to the high voltage electrode 5 and the low voltage electrode 6. A high voltage arc and partial discharge are generated between the high voltage electrode 5 and the low voltage electrode 6, which penetrate the reinforced concrete structure 1. The pulsed strong electric field is conducted by the steel bars in the reinforced concrete structure 1 to penetrate deep into the interior of the reinforced concrete structure 1, so as to maximize the feeding of electrical energy into the interior of the reinforced concrete structure 1, and finally generate a shock wave to break the concrete.

[0040] It should be noted that the electrolyte is brine, which is used to increase the contact area between the electrode and the reinforced concrete structure 1. This embodiment can also simultaneously set up multiple shock wave operation point groups to accommodate the larger volume of the reinforced concrete structure 1, thereby improving operational efficiency.

[0041] A discharge circuit is formed between high-voltage electrode 5 and low-voltage electrode 6, and multiple discharge circuits are formed between high-voltage working point 2 and multiple low-voltage working points 3. A high-voltage arc and partial discharge are generated between high-voltage electrode 5 and low-voltage electrode 6, penetrating the reinforced concrete structure 1. At the instant the high-voltage arc is generated, the air surrounding the arc is rapidly heated and expands, generating a shock wave that breaks the concrete of the reinforced concrete structure 1. Furthermore, the shorter arcs generated by the partial discharge between high-voltage electrode 5 and low-voltage electrode 6 also generate shock waves that act on the concrete. During this process, although the brine does not directly contact the reinforcing steel of the reinforced concrete structure 1, the system utilizes the basic principle of adjusting the electric field distribution through isolated conductors in the medium. It conducts a strong pulsed electric field through the reinforcing steel of the reinforced concrete structure 1, penetrating deep into the interior of the structure, maximizing the input of electrical energy into the interior, and thus achieving the purpose of breaking the concrete through an electrical explosion.

[0042] A small-scale electric arc forms near the arc-shaped area of ​​high-voltage electrode 5, and a breakdown channel gradually forms from high-voltage electrode 5 into the reinforced concrete structure 1. During the extension of the breakdown channel inside the concrete, the extension speed of the channel inside the concrete is greater than the speed of surface discharge formation. Ultimately, a breakdown channel forms first inside the concrete, at which point the breakdown process is complete, and a plasma channel is formed. This plasma channel rapidly expands, generating a strong shock wave that causes the concrete to break. When the distance between high-voltage electrode 5 and low-voltage electrode 6 is greater than a set distance, the distance for surface discharge becomes shorter, which may cause the surface discharge process to develop faster than the internal discharge process, thus forming a discharge channel on the concrete surface first, leading to the inability to generate an effective shock wave. Therefore, the distance between high-voltage operating point 2 and low-voltage operating point 3 is less than a set distance to ensure the smooth implementation of the electro-explosion breaking process.

[0043] The system of the present invention has high efficiency and safety in crushing reinforced concrete structures, and low labor intensity for operators, thus it is highly practical and easy to promote and use.

[0044] In this embodiment, when constructing the liquid storage chamber 4, working holes 10 are drilled and / or external electrode components 9 are arranged on the reinforced concrete structure 1.

[0045] The working hole 10 is a liquid storage chamber 4. The suction cup 91 of the external electrode assembly 9 and the outer wall of the reinforced concrete structure 1 form the liquid storage chamber 4.

[0046] like Figure 1As shown, in this embodiment, three working holes 10 are drilled in the reinforced concrete structure 1. A high-voltage working point 2 is set in one of the working holes 10 and a high-voltage electrode 5 is arranged therein. Low-voltage working points 3 are set in the remaining two working holes 10 and low-voltage electrodes 6 are arranged therein.

[0047] like Figure 2 As shown in this second embodiment, three external electrode assemblies 9 are arranged on the reinforced concrete structure 1. A high-voltage working point 2 is set in one of the external electrode assemblies 9 and a high-voltage electrode 5 is arranged therein. Low-voltage working points 3 are set in the remaining two external electrode assemblies 9 and low-voltage electrodes 6 are arranged therein.

[0048] like Figure 3 As shown, in this third embodiment, a working hole 10 is drilled in the reinforced concrete structure 1, a high-voltage working point 2 is set in the working hole 10 and a high-voltage electrode 5 is arranged, two external electrode assemblies 9 are arranged in the reinforced concrete structure 1, and a low-voltage working point 3 is set in the two external electrode assemblies 9 and a low-voltage electrode 6 is arranged.

[0049] like Figure 4 As shown in this embodiment four, two shock wave operation point groups are arranged on the reinforced concrete structure 1 to improve operation efficiency. Each shock wave operation point group includes a high-voltage operation point 2 and a low-voltage operation point 3. External electrode assemblies 9 are arranged at the operation points according to the method described above.

[0050] In this fifth embodiment, an external electrode assembly 9 is arranged on the reinforced concrete structure 1. A high-voltage working point 2 and a high-voltage electrode 5 are arranged inside the external electrode assembly 9. Multiple working holes 10 are drilled in the reinforced concrete structure 1. Low-voltage working points 3 and low-voltage electrodes 6 are arranged inside the multiple working holes 10.

[0051] Different layout methods are selected based on the size and specific structure of reinforced concrete structure 1 in order to achieve the best operational results.

[0052] In this embodiment, after drilling the working hole 10, the electrode rod 8 is placed into the working hole 10, so that the electrode post 84 at the lower end of the electrode rod 8 is located at the set working point. The high voltage electrode 5 or the low voltage electrode 6 is connected to the cable connection cap 82 at the upper end of the electrode rod 8. The cable connection cap 82 is connected to the electrode post 84 through the high voltage center rod 83.

[0053] Then, electrolyte is injected into the working hole 10 so that the electrode post 84 comes into contact with the electrolyte.

[0054] It should be noted that the electrode rod 8 includes a cylindrical body 81, a cable connector cap 82, a high-voltage center rod 83, an electrode post 84, and an insulator 85. The cylindrical body 81 is a metal component, and the high-voltage center rod 83 is disposed inside the cylindrical body 81. An insulator 85 is disposed between the high-voltage center rod 83, the electrode post 84, and the cylindrical body 81. The cylindrical body 81, the cable connector cap 82, and the high-voltage center rod 83 are used to transmit current.

[0055] In this embodiment, when the working hole 10 is a horizontal drilled hole or an upward drilled hole, a hole sealing device is installed at the opening of the working hole 10.

[0056] It should be noted that after the orifice sealing device is installed, the liquid storage chamber 4 is in a closed state, thereby preventing electrolyte leakage.

[0057] In this embodiment, the depth of the working hole 10 is less than or equal to 60cm.

[0058] In this embodiment, the distance is set to 60cm.

[0059] It should be noted that the depth and spacing of the working holes 10 are both less than or equal to 60cm. The spacing between the high-pressure working point 2 and the low-pressure working point 3, as well as the depth and spacing of the working holes 10, can ensure the smooth implementation of the electric explosion breaking process and avoid the problem that the electric explosion cannot occur due to the distance being too large.

[0060] In this embodiment, when arranging the external electrode assembly 9, the suction cup 91 of the external electrode assembly 9 is attached to the reinforced concrete structure 1, and the output electrode 92 of the external electrode assembly 9 is connected to the high voltage electrode 5 or the low voltage electrode 6.

[0061] Electrolyte is injected into the storage chamber 4 through the water inlet pipe on the suction cup 91, so that the output electrode 92 comes into contact with the electrolyte.

[0062] In this embodiment, before attaching the suction cup 91 of the external electrode assembly 9 to the reinforced concrete structure 1, grease is applied to the end face of the mating ring 911 of the suction cup 91, and the grease comes into contact with the reinforced concrete structure 1.

[0063] It should be noted that the external electrode assembly 9 includes a suction cup 91, an output electrode 92, an insulating tube 93, and a cable connector 94. The suction cup 91 includes a connected disc body and a connecting tube, with the end of the disc body being the disc opening and the end of the connecting tube being the connecting end. The connecting tube is sleeved on the insulating tube 93, and an annular boss 931 is provided on the inner wall of the end of the insulating tube 93 away from the connecting tube. The output electrode 92 includes a connected electrode segment and a threaded segment 921, with the diameter of the electrode segment being larger than the diameter of the threaded segment 921. The threaded segment 921 passes through the end of the insulating tube 93 and connects to the cable connector 94. The stepped surface between the electrode segment and the threaded segment 921 abuts against the end face of the annular boss 931.

[0064] The suction cup 91's structure facilitates its installation onto the insulating tube 93, thus simplifying maintenance and replacement. The output electrode 92 and cable connector 94 are threaded together, ensuring good fixation. The cable connector 94 connects to the electrodes of the pulse power source 7. A mating ring 911, 1.5–2.5 cm wide, is provided at the end of the cup body for mating with the reinforced concrete structure 1. The mating ring 911 increases the contact area between the cup body end face and the reinforced concrete structure 1, improving sealing. Grease further enhances the sealing between the cup body end face and the reinforced concrete structure 1. The mating ring 911, the cup body, and the connecting tube are integrally machined rubber structures. This integrally machined rubber structure provides good strength. A water inlet pipe with a valve is provided on the suction cup 91. Operators inject electrolyte into the suction cup 91 through the water inlet pipe. During injection, a small gap can be left at the top of the suction cup 91 to allow air to escape. The valve is closed after the cup is full.

[0065] In this embodiment, the pulse power source 7 generates high voltage and high current through the following steps:

[0066] The high-voltage capacitor of the pulse power source 7 is charged by the power supply. After the high-voltage capacitor is charged to the working voltage, the gas spark switch is triggered to close, causing the high-voltage capacitor to discharge rapidly and generate a high voltage and large current.

[0067] The power supply can be a battery or an external power source.

[0068] In this embodiment, it will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of the equivalents of the claims be included within the present invention.
