Description

Technical Field

[0001] This invention relates to the field of static rock breaking technology, and in particular to a high-efficiency integrated static rock breaking cartridge. Background Technology

[0002] With the rapid advancement of infrastructure construction, the demand for rock breaking during engineering excavation is increasing daily. However, in sensitive environments such as densely populated areas, structurally unstable or complex buildings, and controlled sea areas, traditional blasting methods are insufficient to meet construction requirements due to issues such as shock waves, noise, and environmental pollution. Therefore, there is an urgent need for a safer and more reliable non-explosive construction method that can meet the needs of construction in sensitive environments while reducing environmental pollution and improving construction efficiency.

[0003] Currently, the main non-explosive rock fracturing methods include carbon dioxide fracturing, hydraulic fracturing, high-energy combustor methods, and static fracturing. Among these, static fracturing is considered an effective alternative to traditional blasting. Static fracturing offers advantages such as no vibration, no harmful gases, no noise, and no flyrock, making it suitable for rock excavation in sensitive environments. Static fracturing utilizes the hydration and expansion properties of static fracturing agents. These agents are grayish-white powders that need to be mixed with water and injected into the borehole. The slurry gradually hardens within the borehole and expands in volume over a certain period, thus achieving the effect of rock fracturing. The application of static rock breaking in underwater environments currently relies mainly on two technical approaches: First, static rock breaking agents are packaged in rolls, primarily using permeable bags for outer packaging. After filling the holes, the rolls need to be compacted. While simple to operate, this method cannot effectively prevent water ingress, and the hydration and expansion process is lengthy, resulting in low rock-breaking efficiency. Second, the formulation of the static rock breaking agent is modified to alter the expansion material. This method requires recalcining the static rock breaking agent powder, making the process cumbersome and the results somewhat unstable. Currently, self-propagating post-heating enhancement technology is commonly used in terrestrial static rock breaking processes to improve the rock-breaking efficiency of static rock breaking agents. However, the application of existing technologies in underwater environments still faces challenges such as sealing difficulties, difficulty in controlling the water-to-powder ratio of the static rock breaking agent, and difficulty in igniting the heating element, limiting their application and promotion in underwater rock breaking. Summary of the Invention

[0004] This invention provides a high-efficiency static rock-breaking integrated explosive cartridge. Its purpose is to provide a wired integrated explosive cartridge that is easy to seal, has a controllable water-to-fuel ratio for the static rock-breaking agent, and an easily ignitable heating element, and can be applied to shallow water or sensitive terrestrial environments, as well as a wireless integrated explosive cartridge for deep water environments.

[0005] To achieve the above objectives, the present invention provides a high-efficiency static rock-breaking integrated explosive cartridge, comprising: Waterproof packaging, made of waterproof and wear-resistant plastic materials; A heat-conducting pipe is inserted through and sealed to the waterproof packaging. The first end of the heat-conducting pipe along its own axis is closed. The heat-conducting pipe has a heating chamber. A heating element capable of releasing heat is disposed in the heating chamber. The heat-conducting pipe and the waterproof packaging enclose an expansion chamber. An expandable static breaker is disposed in the expansion chamber so that the heat of the heating element can be transferred to the static breaker through the heat-conducting pipe. An exhaust pipe has one end sealed to the second end of the heat-conducting pipe along its own extension direction. The heating chamber is connected to the exhaust pipe. The length of the exhaust pipe is greater than or equal to the distance between the second end of the heat-conducting pipe and the water surface. A wired ignition device includes an ignition head, a wire, and a trigger. The trigger and the ignition head are electrically connected through the wire so that the trigger can trigger the ignition head through the wire. The ignition head is disposed in the heating body. At least a portion of the wire passes through the exhaust pipe. The trigger is located above the water surface.

[0006] In one embodiment, both the first and second ends of the heat-conducting pipe protrude from the waterproof packaging.

[0007] In one embodiment, the integrated medicine roll includes a support member disposed within the expansion cavity and surrounding the outer periphery of the heat-conducting pipe. The support member is capable of abutting against the inner wall of the waterproof packaging to shape the waterproof packaging, facilitating the insertion of the integrated medicine roll into the drilled hole.

[0008] In one embodiment, there are multiple supports, which are arranged at intervals along the axial direction of the heat pipe.

[0009] In one embodiment, the heat-conducting pipe is detachably and sealed to the waterproof packaging, and the heat-conducting pipe is detachably and sealed to the exhaust pipe.

[0010] A second aspect of the present invention provides a high-efficiency static rock-breaking integrated explosive cartridge, comprising: Waterproof packaging, made of waterproof and wear-resistant plastic materials; A heat-conducting pipe is inserted through and sealed to the waterproof packaging. The first end of the heat-conducting pipe along its own axis is closed. The heat-conducting pipe has a heating chamber. A heating element capable of releasing heat is disposed in the heating chamber. The heat-conducting pipe and the waterproof packaging enclose an expansion chamber. An expandable static breaker is disposed in the expansion chamber so that the heat of the heating element can be transferred to the static breaker through the heat-conducting pipe. A one-way exhaust sleeve includes a valve body, an elastic element, and a piston. The valve body is sealed to the second end of the heat-conducting pipe. The valve body has a first exhaust channel, a valve port, and a second exhaust channel that are interconnected and arranged sequentially. The first exhaust channel is connected to the heating chamber, and the second exhaust channel is connected to the outside. The piston is disposed at the valve port. The radial dimension of the piston in the valve body is larger than the radial dimension of the first exhaust channel, and the radial dimension of the piston in the valve body is smaller than the radial dimension of the valve port. One end of the elastic element is connected to the piston, and the other end of the elastic element is fixedly connected to the second exhaust channel. A wireless ignition device includes an electronic trigger and a signal transmitter. The electronic trigger is disposed within the heating body, and the signal transmitter is capable of wirelessly triggering the electronic trigger to ignite the heating body.

[0011] In one embodiment, both the first and second ends of the heat-conducting pipe protrude from the waterproof packaging.

[0012] In one embodiment, the integrated medicine roll includes a support member disposed within the expansion cavity, the support member surrounding the outer periphery of the heat-conducting pipe, and the support member being able to abut against the inner wall of the waterproof packaging.

[0013] In one embodiment, there are multiple supports, which are arranged at intervals along the axial direction of the heat pipe.

[0014] In one embodiment, the heat-conducting pipe is detachably and sealed to the waterproof packaging, and the heat-conducting pipe is detachably and sealed to the valve body.

[0015] The above-described solution of the present invention has the following beneficial effects: In this embodiment, the waterproof packaging is sealed to the heat-conducting pipe, reducing the possibility of water entering the expansion chamber and thus reducing the likelihood of water affecting the water-to-powder ratio of the static fracturing agent, thereby ensuring a stable water-to-powder ratio within the expansion chamber. One end of the exhaust pipe is sealed to the heat-conducting pipe, while the other end extends beyond the water surface. This reduces the possibility of water intrusion into the underwater heat-conducting pipe, allowing the heating element inside to ignite smoothly. Furthermore, the exhaust pipe serves not only as a channel for the wire to exit the heating pipe but also as a means to discharge gases and fine particles generated during the combustion of the heating element. This enables the integrated fracturing cartridge of this application to stably and efficiently break rocks in shallow water environments, solving the problem of the inability to use static fracturing agents for rock breaking underwater. Moreover, due to the integrated design of the integrated fracturing cartridge, it can be directly applied in sensitive terrestrial environments to improve rock breaking efficiency. The integrated fracturing cartridge has excellent sealing performance, effectively reducing the risk of blowouts caused by the static fracturing agent's sensitivity to temperature and humidity, making it suitable for static fracturing operations in various complex and sensitive environments.

Detailed Implementation

[0019] To make the technical problems, solutions, and advantages of this invention clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] The high-efficiency static rock-breaking integrated explosive cartridges provided in this application can be divided into wired and wireless high-efficiency static rock-breaking integrated explosive cartridges according to the application environment. The wired integrated explosive cartridges capable of high-efficiency static rock breaking can be used in shallow water environments, such as drilling into rock masses below the water surface, and can also be used in sensitive terrestrial environments for rock breaking. The wireless integrated explosive cartridges capable of high-efficiency static rock breaking can be used in drilling into rock masses below the water surface in deep water environments.

[0023] Specifically, please refer to Figure 1 The wired integrated drug roll 100 includes a waterproof packaging 1, a heat-conducting pipe 2, an exhaust pipe 5, and a wired ignition device 6, and is suitable for shallow water or sensitive land environments.

[0024] Waterproof packaging 1 is made of waterproof and wear-resistant plastic material. The material of waterproof packaging 1 can be a waterproof material with flexibility, certain waterproof performance and certain strength, such as non-woven fabric, asbestos or polymer composite film material, to facilitate the installation of other components.

[0025] Please see Figure 1 The heat-conducting pipe 2 passes through the waterproof packaging 1 and is sealed to it. Specifically, at least one end of the heat-conducting pipe 2 protrudes from the waterproof packaging 1 along its axial direction. The waterproof packaging 1 can be secured to the outer periphery of the heat-conducting pipe 2 with an annular clip to ensure a sealed connection between the waterproof packaging 1 and the heat-conducting pipe 2. The heat-conducting pipe 2 has a heating chamber 2a, within which a heating element 3 capable of releasing heat is disposed. The heating element 3 can be made of a material that releases heat through a reaction; for example, the heating element 3 can be iron powder and / or aluminum powder. The heat-conducting pipe 2 and the waterproof packaging 1 enclose an expansion chamber 1a, within which an expandable static breaker 4 is disposed, allowing the heat generated by the heating element 3 to be transferred to the static breaker 4 through the heat-conducting pipe 2. The heat-conducting pipe 2 can be made of a material with waterproof properties and good thermal conductivity, such as a ceramic pipe or a steel pipe, to reduce the possibility of water seeping into the heating chamber 2a through the heat-conducting pipe 2, while simultaneously ensuring good transfer of the heat generated by the heating element 3 to the static breaker 4.

[0026] For example, please refer to Figure 1 When the heat-conducting pipe 2 is inserted into the waterproof packaging 1, the static rock-breaking agent 4, prepared according to a preset water-to-agent ratio, is poured into the expansion chamber 1a. Then, the waterproof packaging 1 is sealed to the heat-conducting pipe 2 to reduce the possibility of water, such as seawater, entering the expansion chamber 1a, thereby reducing the possibility of seawater affecting the water-to-agent ratio of the static rock-breaking agent 4 and ensuring the stability of the water-to-agent ratio of the static rock-breaking agent 4 within the expansion chamber 1a. When the heating element 3 located in the heating chamber 2a reacts and generates heat, this heat can be transferred to the static rock-breaking agent 4 via the heat-conducting pipe 2, heating the static rock-breaking agent 4, accelerating its hydration reaction rate, and instantly increasing its expansion pressure for efficient rock breaking.

[0027] Please see Figure 1 The first end of the heat pipe 2 along its own axis is closed, and the second end of the heat pipe 2 along its own axis is sealed and connected to the end of the exhaust pipe 5 along its own extension direction. The heating chamber 2a is connected to the exhaust pipe 5. The length of the exhaust pipe 5 is greater than or equal to the distance between the second end of the heat pipe 2 and the water surface 300. This allows the other end of the exhaust pipe 5 to extend beyond the water surface 300 while the first end of the exhaust pipe 5 is sealed and connected to the second end of the heat pipe 2. This reduces the possibility of water flowing into the heat pipe 2 through the exhaust pipe 5, providing the necessary conditions for the heating element 3 in the heat pipe 2 to react and generate heat, so that the heating element 3 in the heat pipe 2 can be ignited smoothly.

[0028] Please see Figure 1 The wired ignition device 6 includes an ignition head 61, a wire 62, and a trigger 63. The trigger 63 and the ignition head 61 are electrically connected via the wire 62, enabling the trigger 63 to trigger the ignition head 61 through the wire 62. The ignition head 61 is disposed within the heating body 3, at least a portion of the wire 62 extends through the exhaust pipe 5, and the trigger 63 is located above the water surface 300. For example, the trigger 63, positioned above the water surface 300, can be charged and then discharged, transmitting high-voltage electricity to the ignition head 61 through the wire 62 extending through the exhaust pipe 5, thereby igniting the heating body 3. The heat generated by the heating body 3 then heats the static decomposing agent 4 through the heat pipe 2. It should be noted that the heating body 3 generates gas and fine particles during the exothermic reaction process, which can be discharged into the external environment through the exhaust pipe 5.

[0029] In this embodiment, the waterproof packaging 1 is sealed to the heat-conducting pipe 2, reducing the possibility of water entering the expansion chamber 1a and thus reducing the possibility of water affecting the water-to-powder ratio of the static fracturing agent 4, thereby ensuring that the water-to-powder ratio of the static fracturing agent 4 in the expansion chamber 1a remains stable. One end of the exhaust pipe 5 is sealed to the heat-conducting pipe 2, and the other end of the exhaust pipe 5 can extend beyond the water surface 300. On the one hand, this reduces the possibility of water intrusion into the underwater heat-conducting pipe 2, allowing the heating element 3 inside the heat-conducting pipe 2 to ignite smoothly. On the other hand, the exhaust pipe 5 can not only serve as a channel for the wire 62 to exit from the heating pipe, but also be used to discharge the gas and fine particles generated by the combustion of the heating element 3, so that the integrated explosive cartridge 100 of this application can stably and efficiently break the rock mass 200 in shallow water environments, thus solving the problem that the static fracturing agent 4 cannot be used for rock breaking underwater. Furthermore, due to the integrated design of the integrated explosive cartridge 100 of this application, when the integrated explosive cartridge 100 is applied to a sensitive terrestrial environment, the integrated explosive cartridge 100 can be directly applied to improve rock breaking efficiency. The integrated fracturing cartridge 100 has excellent sealing performance, effectively reducing the number of nozzles caused by the static fracturing agent 4 being sensitive to temperature and humidity in the environment, making the integrated fracturing cartridge 100 suitable for static fracturing construction in various complex and sensitive environments.

[0030] In one embodiment, please refer to Figure 1 The first and second ends of the heat-conducting pipe 2 protrude from the waterproof packaging 1 so that the heat-conducting pipe 2 can penetrate the waterproof packaging 1, thereby increasing the contact area between the heat-conducting pipe 2 and the static rock-breaking agent 4. For example, the static rock-breaking agent 4 set in the waterproof packaging 1 can be heated by the heat released by the heating body 3 in the heat-conducting pipe 2 in the axial direction, so as to accelerate the hydration reaction of the static rock-breaking agent 4 and facilitate the instantaneous increase of the expansion pressure of the static rock-breaking agent 4 for efficient rock breaking.

[0031] For example, please refer to Figure 1First, the waterproof packaging 1 is sealed and connected to the first end of the heat-conducting pipe 2 using a ring-shaped buckle. After the static breaker agent 4 is poured into the expansion chamber 1a, the waterproof packaging 1 is then sealed and connected to the second end of the heat-conducting pipe 2 using the ring-shaped buckle again. This seals the static breaker agent 4 within the expansion chamber 1a, reducing the possibility of water affecting the water-to-agent ratio of the static breaker agent 4. For example, the ring-shaped buckle may include a ring-shaped clamping part and a tightening part. The tightening part allows the size of the clamping part to be reduced. The clamping part is located on the outer periphery of the waterproof packaging 1. The tightening part securely clamps the waterproof packaging 1 to the first end of the heat-conducting pipe 2, thus sealing the waterproof packaging 1 and the heat-conducting pipe 2 together.

[0032] In one embodiment, please refer to Figure 1 The integrated cartridge 100 includes a support member 7 disposed within the expansion cavity 1a. The support member 7 surrounds the outer periphery of the heat-conducting pipe 2 and is capable of abutting against the inner wall of the waterproof packaging 1. For example, the support member 7 is configured as an annular shape, possessing sufficient strength to support the shape of the flexible waterproof packaging 1, so as to facilitate the insertion of the integrated cartridge 100 into the borehole of the rock mass 200 to be broken, and to ensure sufficient contact between the integrated cartridge 100 and the inner wall of the borehole, thereby reducing the loss of expansion pressure. The support member 7 can be a reinforcing bar or other components with similar shaping and supporting functions, such as an annular support ring, a skeleton support member, an elastic positioning ring, etc.

[0033] For example, after the static fracturing agent 4 is injected into the expansion chamber 1a, the support member 7 can ensure that the outer diameter of the integrated cartridge 100 is basically consistent with the diameter of the borehole, which makes it convenient to install the integrated cartridge 100 into the borehole, and at the same time, it can make the integrated cartridge 100 fully contact the borehole to reduce the loss of expansion pressure.

[0034] For example, the waterproof packaging 1, made of waterproof and wear-resistant plastic material, can ensure that the integrated cartridge 100 is not easily damaged when it is inserted into the borehole. At the same time, it can work with the support 7 to shape the integrated cartridge 100 after the static fracturing agent 4 is injected, so as to facilitate the installation of the integrated cartridge 100 into the borehole of the rock mass 200 and reduce the loss of expansion pressure.

[0035] In one embodiment, please refer to Figure 1 The number of support members 7 is multiple, and the multiple support members 7 are arranged at intervals along the axial direction of the heat conduction pipe 2. The multiple support members 7 with a certain strength can better support the shape of the flexible waterproof packaging 1, so as to facilitate the insertion of the integrated drug roll 100 of this application into the borehole of the rock mass 200 to be broken, and can make the integrated drug roll 100 fully contact the inner wall of the borehole to reduce the loss of expansion pressure.

[0036] In one embodiment, please refer to Figure 1 and Figure 2(a) The heat-conducting pipe 2 is detachably and sealed to the waterproof packaging 1, and the heat-conducting pipe 2 is detachably and sealed to the exhaust pipe 5, so that the heat-conducting pipe 2 can be recycled, which helps to reduce the usage cost of the integrated drug roll 100 of this application.

[0037] For example, please refer to Figure 2 (a) The heat-conducting pipe 2 and the exhaust pipe 5 are detachably and sealingly connected by a threaded ferrule assembly. The first end of the heat-conducting pipe 2 can be detachably sealed by a threaded plug. For example, the integrated cartridge 100 may also include rubber sealing rings, which can be disposed at both ends of the heat-conducting pipe 2 to improve the sealing performance between the heat-conducting pipe 2 and the exhaust pipe 5, as well as the sealing performance of the first end of the heat-conducting pipe 2.

[0038] Please see Figure 3 The second aspect of this application provides another wireless, high-efficiency static rock-breaking integrated explosive cartridge 100, including a waterproof packaging 1, a heat-conducting pipe 2, a one-way venting sleeve 8, and a wireless ignition device, suitable for deep-water environments.

[0039] Waterproof packaging 1 is made of waterproof and wear-resistant plastic material. The material of waterproof packaging 1 can be a waterproof material with flexibility, certain waterproof performance and certain strength, such as non-woven fabric, asbestos or polymer composite film material, to facilitate the installation of other components.

[0040] Please see Figure 3 The heat-conducting pipe 2 passes through the waterproof packaging 1 and is sealed to it. Specifically, at least one end of the heat-conducting pipe 2 protrudes from the waterproof packaging 1 along its axial direction. The waterproof packaging 1 can be secured to the outer periphery of the heat-conducting pipe 2 with an annular clip to ensure a sealed connection between the waterproof packaging 1 and the heat-conducting pipe 2. The heat-conducting pipe 2 has a heating chamber 2a, within which a heating element 3 capable of releasing heat is disposed. The heating element 3 can be made of a material that releases heat through a reaction; for example, the heating element 3 can be iron powder and / or aluminum powder. The heat-conducting pipe 2 and the waterproof packaging 1 enclose an expansion chamber 1a, within which an expandable static breaker 4 is disposed, allowing the heat generated by the heating element 3 to be transferred to the static breaker 4 through the heat-conducting pipe 2. The heat-conducting pipe 2 can be made of a material with waterproof properties and good thermal conductivity, such as a ceramic pipe or a steel pipe, to reduce the possibility of water seeping into the heating chamber 2a through the heat-conducting pipe 2, while simultaneously ensuring good transfer of the heat generated by the heating element 3 to the static breaker 4.

[0041] For example, please refer to Figure 3When the heat-conducting pipe 2 is inserted into the waterproof packaging 1, the static rock-breaking agent 4, prepared according to a preset water-to-agent ratio, is poured into the expansion chamber 1a. The waterproof packaging 1 is then sealed to the heat-conducting pipe 2 to reduce the possibility of water, such as seawater, entering the expansion chamber 1a, thereby reducing the likelihood of seawater affecting the water-to-agent ratio of the static rock-breaking agent 4 and ensuring a stable water-to-agent ratio within the expansion chamber 1a. When the heating element 3 in the heating chamber 2a reacts and generates heat, this heat is transferred to the static rock-breaking agent 4 via the heat-conducting pipe 2, heating the static rock-breaking agent 4, accelerating its hydration reaction rate, and instantly increasing its expansion pressure for efficient rock breaking.

[0042] Please see Figure 2 (b) Figure 3 and Figure 4The heat pipe 2 is closed at its first end along its own axial direction. The one-way exhaust sleeve 8 includes a valve body 81, an elastic element 82, and a piston 83. The valve body 81 has a first exhaust channel 8a, a valve port 8b, and a second exhaust channel 8c that are interconnected and arranged sequentially. The first exhaust channel 8a is connected to the heating chamber 2a so that the gas and fine particles generated by the heating element 3 can enter the first exhaust channel 8a. The second exhaust channel 8c is connected to the outside. The piston 83 is disposed at the valve port 8b and can move along the axial direction of the valve body 81 within the valve port 8b. The radial dimension of the piston 83 in the valve body 81 is larger than the radial dimension of the first exhaust channel 8a, and the radial dimension of the piston 83 in the valve body 81 is smaller than the radial dimension of the valve port 8b. One end of the elastic element 82 is connected to the piston 83, and the other end of the elastic element 82 is fixedly connected to the second exhaust channel 8c. For example, before the heating element 3 begins to react and release heat, under the action of water pressure and the weight of the piston 83, the elastic element 82 can be in a stretched or balanced state, allowing the piston 83 located in the valve port 8b to block the first exhaust passage 8a, thereby reducing the possibility of water, such as seawater, entering the heating chamber 2a through the first exhaust passage 8a. When the heating element 3 begins to react and release heat, generating gas and fine particles, the pressure in the heating chamber 2a and the first exhaust passage 8a increases. When the pressure in the first exhaust passage 8a exceeds the sum of the water pressure and the elastic restoring force of the elastic element 82, the piston 83 can be pushed open, allowing the gas and fine particles in the first exhaust passage 8a to be discharged through the valve port 8b and the second exhaust passage 8c. During this process, due to the higher pressure in the first exhaust passage 8a, the gas and fine particles in the first exhaust passage 8a, when ejected from the first exhaust passage 8a, can prevent water from entering the first exhaust passage 8a. When the pressure in the heating chamber 2a and the first exhaust channel 8a decreases as gas and fine particles are released, and when the pressure in the first exhaust channel 8a is less than or equal to the sum of the water pressure and the elastic restoring force of the elastic element 82, the piston 83 can block the first exhaust channel 8a again to reduce the possibility of water entering the heating chamber 2a through the first exhaust channel 8a, so that the one-way exhaust sleeve 8 of this application can become an exhaust structure that only allows gas and fine particles to pass through in one direction.

[0043] Please see Figure 3The wireless ignition device includes an electronic trigger 91 and a signal transmitter 92. The electronic trigger 91 is disposed within the heating body 3. The signal transmitter 92 can wirelessly trigger the electronic trigger 91 to ignite the heating body 3, so that the heat generated by the heating body 3 heats the static fracturing agent 4 through the heat pipe 2. For example, when the integrated explosive cartridge 100 of this application is used to break up rock mass 200 buried at a relatively deep depth below the water surface 300, the operator can ride in a construction vessel 400 and hold the signal transmitter 92. When the electronic trigger 91 is within the control range of the signal transmitter 92, the operator can wirelessly transmit an ignition signal to the electronic trigger 91 through the signal transmitter 92, so that the electronic trigger 91 can ignite the heating body 3, so that the heat generated by the heating body 3 heats the static fracturing agent 4 through the heat pipe 2. For example, the signal transmitting end of the signal transmitter 92 can be placed in water for ignition operation. Transmitting the ignition signal in water can reduce external signal interference to a certain extent.

[0044] In this embodiment, the waterproof packaging 1 is sealed to the heat-conducting pipe 2, reducing the possibility of water entering the expansion chamber 1a and thus reducing the possibility of water affecting the water-to-agent ratio of the static fracturing agent 4, thereby ensuring that the water-to-agent ratio of the static fracturing agent 4 in the expansion chamber 1a remains stable. One end of the valve body 81 of the one-way venting sleeve 8 is sealed to the heat-conducting pipe 2. The one-way venting sleeve 8 can only vent in one direction, allowing the one-way venting sleeve 8 to not only expel the gas and fine particles generated by the reaction of the heating element 3 to the outside, but also to prevent the heat-conducting pipe 2 located below the water surface 300 from being invaded by water. This enables the integrated explosive cartridge 100 of this application to stably and efficiently break the rock mass 200 in deep water environments, solving the problem that the static fracturing agent 4 cannot be used for rock breaking in deep water environments. Furthermore, the integrated explosive cartridge 100 has excellent sealing performance, effectively reducing the occurrence of nozzles caused by the static fracturing agent 4's sensitivity to temperature and humidity in the environment.

[0045] In one embodiment, please refer to Figure 3 The first and second ends of the heat-conducting pipe 2 protrude from the waterproof packaging 1 so that the heat-conducting pipe 2 can penetrate the waterproof packaging 1, thereby increasing the contact area between the heat-conducting pipe 2 and the static rock-breaking agent 4. For example, the static rock-breaking agent 4 set in the waterproof packaging 1 can be heated by the heat released by the heating body 3 in the heat-conducting pipe 2 in the axial direction, so as to accelerate the hydration reaction of the static rock-breaking agent 4 and facilitate the instantaneous increase of the expansion pressure of the static rock-breaking agent 4 for efficient rock breaking.

[0046] For example, please refer to Figure 3First, the waterproof packaging 1 is sealed and connected to the first end of the heat-conducting pipe 2 using a ring-shaped buckle. After the static breaker agent 4 is poured into the expansion chamber 1a, the waterproof packaging 1 is then sealed and connected to the second end of the heat-conducting pipe 2 using the ring-shaped buckle again. This seals the static breaker agent 4 within the expansion chamber 1a, reducing the possibility of water affecting the water-to-agent ratio of the static breaker agent 4. For example, the ring-shaped buckle may include a ring-shaped clamping part and a tightening part. The tightening part allows the size of the clamping part to be reduced. The clamping part is located on the outer periphery of the waterproof packaging 1. The tightening part securely clamps the waterproof packaging 1 to the first end of the heat-conducting pipe 2, thus sealing the waterproof packaging 1 and the heat-conducting pipe 2 together.

[0047] In one embodiment, please refer to Figure 3 The integrated cartridge 100 includes a support member 7 disposed within the expansion cavity 1a. The support member 7 surrounds the outer periphery of the heat-conducting pipe 2 and is capable of abutting against the inner wall of the waterproof packaging 1. For example, the support member 7 is configured as an annular shape, possessing sufficient strength to support the shape of the flexible waterproof packaging 1, so as to facilitate the insertion of the integrated cartridge 100 into the borehole of the rock mass 200 to be broken, and to ensure sufficient contact between the integrated cartridge 100 and the inner wall of the borehole, thereby reducing the loss of expansion pressure. The support member 7 can be a reinforcing bar or other components with similar shaping and supporting functions, such as an annular support ring, a skeleton support member, an elastic positioning ring, etc.

[0048] For example, after the static fracturing agent 4 is injected into the expansion chamber 1a, the support member 7 can ensure that the outer diameter of the integrated cartridge 100 is basically consistent with the diameter of the borehole, which makes it convenient to install the integrated cartridge 100 into the borehole, and at the same time, it can make the integrated cartridge 100 fully contact the borehole to reduce the loss of expansion pressure.

[0049] For example, the waterproof packaging 1, made of waterproof and wear-resistant plastic material, can ensure that the integrated cartridge 100 is not easily damaged when it is inserted into the borehole. At the same time, it can work with the support 7 to shape the integrated cartridge 100 after the static fracturing agent 4 is injected, so as to facilitate the installation of the integrated cartridge 100 into the borehole of the rock mass 200 and reduce the loss of expansion pressure.

[0050] In one embodiment, please refer to Figure 3 The number of support members 7 is multiple, and the multiple support members 7 are arranged at intervals along the axial direction of the heat conduction pipe 2. The multiple support members 7 with a certain strength can better support the shape of the flexible waterproof packaging 1, so as to facilitate the insertion of the integrated drug roll 100 of this application into the borehole of the rock mass 200 to be broken, and can make the integrated drug roll 100 fully contact the inner wall of the borehole to reduce the loss of expansion pressure.

[0051] In one embodiment, please refer to Figure 3 and Figure 4The heat-conducting pipe 2 is detachably and sealed to the waterproof packaging 1, and the heat-conducting pipe 2 is detachably and sealed to the valve body 81, so that the heat-conducting pipe 2 can be recycled, which helps to reduce the usage cost of the integrated drug roll 100 of this application.

[0052] For example, please refer to Figure 3 and Figure 4 The heat-conducting pipe 2 and the valve body 81 can be connected by threads to achieve a detachable and sealed connection. The first end of the heat-conducting pipe 2 can be detachably sealed by a threaded plug. For example, the integrated cartridge 100 may also include rubber sealing rings, which can be disposed at both ends of the heat-conducting pipe 2 to improve the sealing performance between the heat-conducting pipe 2 and the exhaust pipe 5, as well as the sealing performance of the first end of the heat-conducting pipe 2.

[0053] For example, the method of using the high-efficiency static rock-breaking integrated explosive cartridge 100 of this application is as follows: 1) Drill holes and determine the dimensions of the fittings: First, the rock mass 200 is drilled using a drilling rig. A heat pipe 2 of appropriate size is selected according to the borehole diameter as the main body of the heating part of the integrated cartridge 100. Then, the first end of the heat pipe 2 is sealed. Finally, an exhaust pipe 5 or a one-way exhaust sleeve 8 that is compatible with the heat pipe 2 is selected according to the on-site construction conditions.

[0054] 2) Assembly and manufacturing of integrated medicine rolls 100: According to construction requirements, the heating element 3 is sealed in a heat-conducting pipe 2 of suitable material according to the specified filling amount and density, and the ignition head 61 or electronic trigger 91 is embedded in the heating element 3. The first end of the heat-conducting pipe 2 is sealed, and the second end of the heat-conducting pipe 2 is equipped with an exhaust pipe 5 or a one-way exhaust sleeve 8 according to the on-site construction conditions. A waterproof package 1 of suitable material is selected, and the material of the waterproof package 1 is cut according to the size of the drill hole so that the diameter of the "sleeve-type" waterproof package 1 after cutting is slightly smaller than the diameter of the drill hole. The "sleeve-type" waterproof package 1 is installed on the outer periphery of the heat-conducting pipe 2, and at the same time, an annular support 7 is installed inside the waterproof package 1, i.e., in the expansion cavity 1a, as an internal support to fix the shape of the waterproof package 1. The upper and lower ends of the waterproof package 1 are sealed with annular buckles (the upper end needs to be filled with static rock-breaking agent 4 before use and then sealed). Through the above steps, an integrated explosive cartridge 100 for high-efficiency static rock breaking is produced.

[0055] 3) Use the integrated explosive cartridge 100 for rock breaking: Before using the integrated rock-breaking cartridge 100, prepare the static rock-breaking agent 4 according to the preset ratio. Ensuring the static rock-breaking agent 4 has good fluidity, quickly pour it into the "sleeve-type" waterproof packaging 1, then seal the top with a ring buckle. Finally, place the integrated rock-breaking cartridge 100 into the borehole. For wired integrated rock-breaking cartridges 100, ensure the vent pipe 5 is above the water surface 300. Once the static rock-breaking agent 4 reaches its initial solidification state, ignite the heating element 3 using the trigger 63 or signal transmitter 92 to achieve full-length heating within the borehole, accelerating the hydration reaction of the static rock-breaking agent 4 and instantly increasing the expansion pressure, thus achieving efficient static rock breaking.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
