Description

Technical Field

[0001] This invention belongs to the field of static blasting technology, specifically relating to a rapid charging device and method for static blasting. Background Technology

[0002] Static blasting is a non-explosive fracturing technique that utilizes a static fracturing agent mixed with water to undergo a chemical reaction and generate expansion force, thereby causing rock, concrete, or other brittle media to fracture. Compared with traditional explosive blasting, static blasting has advantages such as higher safety, less vibration, lower noise, and lower risk of flyrock. Therefore, it has been widely used in urban built-up areas, slope stabilization, underground engineering, structure demolition, and other engineering scenarios with high requirements for environmental disturbance.

[0003] However, existing static blasting methods still have certain shortcomings. Typically, during construction, the static fracturing agent needs to be manually mixed with water on-site, and then the mixed slurry is manually poured into the borehole. This process involves high labor intensity, low operational efficiency, discontinuous slurry delivery, and frequent contact with the slurry by personnel, affecting the overall efficiency and safety of static blasting operations. Especially when there are many boreholes and the construction pace is fast, manual loading is more prone to uneven loading, slurry overflow, and borehole contamination, further reducing construction quality. Furthermore, the static fracturing agent gradually generates expansion pressure after reacting in the borehole. If the borehole opening is not properly sealed, slurry can easily spray out, causing material waste and potentially adverse effects on construction personnel and the surrounding environment. While existing technologies include simple borehole sealing methods, the sealing structure is often relatively simple, with limited resistance to ejection, making it difficult to ensure both rapid loading and a good borehole seal. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as low efficiency, high labor intensity, and insufficient orifice sealing effect of manual stirring and loading of static fracturing agents. It provides a rapid static blasting charging device and method to achieve rapid stirring, transportation, and loading of static fracturing agents, improve charging efficiency, enhance the sealing ability of blast hole orifices, and reduce the risk of slurry ejection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a static blasting rapid charging device, comprising a stirring and storing slurry assembly, a slurry conveying assembly, a borehole sealing assembly, and a self-locking clamping assembly; the stirring and storing slurry assembly is used to mix and stir the static fracturing agent and water; the slurry conveying assembly is used to convey the stirred slurry into the borehole; the borehole sealing assembly is disposed at the borehole opening for sealing the borehole; the self-locking clamping assembly is connected to the borehole sealing assembly and extends into the depth of the borehole for limiting the outward displacement of the borehole sealing assembly through anchoring force during the expansion reaction of the deep slurry.

[0006] Furthermore, the mixing and storage assembly includes a storage tank, a cover plate, a drive motor, a mixing shaft, and mixing blades. The cover plate is detachably installed on the top of the storage tank, the drive motor is fixedly installed on the upper surface of the cover plate, the output shaft of the drive motor passes through the cover plate and is coaxially connected to the mixing shaft, and the mixing blades are fixedly installed at the lower end of the mixing shaft and located inside the storage tank.

[0007] Furthermore, the cover plate is provided with a feed inlet for adding static crushing agent and water into the slurry storage tank, and the bottom of the slurry storage tank is provided with a slurry outlet.

[0008] Furthermore, the grouting assembly includes a grouting pump, a grout suction pipe, and a grouting hose. The grouting pump is located outside the grout storage tank. One end of the grout suction pipe is connected to the grout outlet at the bottom of the grout storage tank, and the other end is connected to the inlet of the grouting pump. One end of the grouting hose is connected to the outlet of the grouting pump, and the other end extends into the blast hole.

[0009] Furthermore, the orifice sealing assembly includes a blowout stopper, which is located at the orifice of the blast hole and has an overall truncated cone structure that is wider at the top and narrower at the bottom. The blowout stopper is provided with a through hole for the slurry delivery hose to pass through, and a wire hole for the self-locking clamping assembly to pass through.

[0010] Furthermore, the slurry delivery hose is sealed to the through hole to prevent the slurry from puncturing the through hole.

[0011] Furthermore, the self-locking clamping assembly includes a flexible connecting cable, a deep anchor, and a top locking member. The lower end of the flexible connecting cable is fixedly connected to the deep anchor, and its upper end passes through the wire hole and is locked and fixed by the top locking member, so that the flexible connecting cable is in a pre-tensioned state inside the blast hole. The deep anchor is placed deep in the blast hole and is used to be submerged in the static fracturing agent slurry. The top locking member is set above the blowout stopper and is used to lock the flexible connecting cable after it passes through the wire hole after tension.

[0012] Furthermore, the length of the flexible connecting cable is 2m to 3m.

[0013] Furthermore, the deep anchor has a conical or inverted conical structure and is made of wood, composite materials, or metal.

[0014] A method for rapid static blasting charging, using the aforementioned rapid static blasting charging device, includes the following steps: S1. Install the cover plate on the top of the slurry storage tank, and fix the drive motor, stirring shaft and stirring blades on the slurry storage tank; S2. Secure the lower end of the flexible connecting cable to the deep anchor, and pass the upper end of the flexible connecting cable through the cable hole. Then, insert the deep anchor and the flexible connecting cable into the borehole together. Install the blowout stop plug at the borehole opening. Manually or mechanically tighten the flexible connecting cable upwards from outside the hole until it is in a straight tension state inside the hole. Then, use the top locking device to lock and fix the flexible connecting cable above the blowout stop plug. Pass the grout delivery hose through the through hole on the blowout stop plug and extend it into the borehole. S3. Add static crushing agent and water to the slurry storage tank, start the drive motor, and drive the stirring blades to stir the slurry; S4. Start the grouting pump and deliver the well-mixed grout to the borehole through the grout suction pipe and grout delivery hose, so that the deep anchors are completely submerged in the grout. S5. After the blast hole is filled with explosives, stop the grouting pump and pull out the grout delivery hose.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a mixing and storage assembly consisting of a drive motor, a mixing shaft, and mixing blades, the static fracturing agent and water are automatically mixed, reducing manual operation and improving the uniformity of slurry mixing and construction efficiency; 2.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figure 1 As shown, this embodiment provides a static blasting rapid charging device, including a stirring and storage assembly, a slurry delivery assembly, an orifice sealing assembly, and a self-locking clamping assembly.

[0022] The mixing and storage assembly includes a storage tank 11, a cover plate 12, a drive motor 13, a mixing shaft 14, and mixing blades 15. The storage tank 11 holds the static breaking agent slurry. A detachable cover plate 12 is installed on the top of the storage tank 11, and the cover plate 12 is fixed to the top of the storage tank 11 by bolts, facilitating disassembly, cleaning, and maintenance. The drive motor 13 is fixedly installed on the upper surface of the cover plate 12. The output shaft of the drive motor 13 passes through the center of the cover plate 12 and is coaxially fixedly connected to the mixing shaft 14. Mixing blades 15 are fixedly installed at the lower end of the mixing shaft 14, located inside the storage tank 11, for thoroughly mixing the static breaking agent and water. An inlet 121 is provided on the cover plate 12 for adding the static breaking agent and water into the storage tank 11. An outlet 111 is provided at the bottom of the storage tank 11 for discharging the uniformly mixed slurry.

[0023] After the drive motor 13 is powered on, it drives the stirring shaft 14 to rotate. The stirring shaft 14 drives the stirring blades 15 at its lower end to rotate inside the slurry storage tank 11, thereby forcibly shearing, mixing, and dispersing the static fracturing agent and water in the slurry storage tank 11, so that the two are fully mixed in a short time to form a uniform slurry. The technical effect is that it realizes the automatic mixing of static fracturing agent and water, replacing the traditional manual mixing method. This not only improves the uniformity and consistency of slurry mixing, but also significantly reduces the intensity of manual labor, improves the mixing efficiency, and provides a stable source of slurry for subsequent continuous grouting operations.

[0024] The grouting assembly includes a grouting pump 21, a suction pipe 22, and a grouting hose 23. The grouting pump 21 is located outside the grout storage tank 11 and placed on the ground. One end of the suction pipe 22 is connected to the grout outlet 111 at the bottom of the grout storage tank 11, and the other end is connected to the inlet of the grouting pump 21. One end of the grouting hose 23 is connected to the outlet of the grouting pump 21, and the other end extends into the borehole 5. By starting the grouting pump 21, the uniformly stirred grout in the grout storage tank 11 can be drawn and transported into the borehole 5, realizing the rapid filling of static fracturing agent grout.

[0025] After the grouting pump 21 starts, it draws the well-mixed grout from the bottom of the grout storage tank 11 through the suction pipe 22. The grout is then pressurized by the grouting pump 21 and transported to the borehole 5 through the grout delivery hose 23, achieving continuous and stable grout delivery from the storage tank 11 to the borehole 5. The technical advantages are: it realizes mechanized and continuous grout delivery and filling, replacing the traditional manual grouting method, significantly improving the loading speed and efficiency, while reducing grout splashing and waste during delivery, ensuring precise control of the loading amount, and reducing the risk of direct contact between construction personnel and the grout.

[0026] The orifice sealing assembly includes a blowout stopper 31. The blowout stopper 31 is positioned at the orifice opening of the borehole 5 and has a truncated cone structure that is wider at the top and narrower at the bottom to facilitate a wedge-shaped seal with the orifice opening. The blowout stopper 31 has a through hole 311 through which the grout delivery hose 23 passes and extends into the borehole 5. The grout delivery hose 23 seals against the through hole 311, effectively preventing grout from puncturing the through hole. The blowout stopper 31 also has a wire passage hole 312 for the self-locking clamping assembly to pass through and form an assembly connection with it.

[0027] The anti-spray plug 31, with its frustum-shaped structure, is inserted into the borehole 5 opening, forming a wedge-shaped compression seal between the conical surface and the borehole wall, thus creating a preliminary sealing barrier at the borehole 5 opening. The sealing fit between the through hole 311 and the grout delivery hose 23 ensures that grout will not spray outwards along the gap between the outer wall of the grout delivery hose 23 and the through hole 311 during grouting. Its technical advantages are: forming a reliable sealing structure at the borehole opening, effectively preventing grout from overflowing or spraying out during grouting, avoiding material waste and environmental pollution, and simultaneously providing a reaction force support foundation for the deep anchoring force provided by the subsequent self-locking clamping components.

[0028] The self-locking clamping assembly includes a flexible connecting cable 41, a deep anchor 42, and a top locking member 43. The flexible connecting cable 41 is 2m to 3m long, with its lower end fixedly connected to the deep anchor 42, and its upper end passing upwards through the wire hole 312 on the blowout stopper 31, and is locked in place by the top locking member 43 located above and outside the blowout stopper 31. The deep anchor 42 has a conical or inverted conical structure and can be made of wood, composite materials, or metal. During explosive loading, it is placed deep within the borehole 5 and submerged in the static fracturing agent slurry. The top locking member 43 is used to lock the flexible connecting cable 41 after tensioning it outside the borehole, ensuring that the flexible connecting cable 41 remains in a straight, pre-tensioned state without axial slack within the borehole 5.

[0029] Before grouting begins, the deep anchor 42 is inserted into the depth of the borehole 5, and the flexible connecting cable 41 is pre-tensioned outside the borehole opening via the top locking member 43. During grouting, the deep anchor 42 is completely submerged in the static fracturing agent grout. As the static fracturing agent undergoes a hydration and expansion reaction, the grout volume at the depth of the borehole 5 expands and gradually solidifies, firmly anchoring the deep anchor 42 in the grout / rock mass medium at the depth of the borehole 5. When the expansion pressure is transmitted to the borehole opening and pushes the blowout stopper 31 outward, the pre-tensioned flexible connecting cable 41 transmits tension to the deep anchor 42. The deep anchor 42, relying on the anchoring force generated after being anchored by the deep grout, pulls the blowout stopper 31 in the opposite direction through the flexible connecting cable 41 and the top locking member 43, thereby effectively resisting the borehole opening expansion pressure and preventing the blowout stopper 31 from being blown out. Its technical effect is as follows: through the self-locking method of "deep anchoring + pre-tensioning", the deep anchor is anchored to the depth of the blast hole by the expansion reaction of the grout itself, forming a reverse constraint force that balances the expansion force at the borehole opening. This fundamentally improves the mechanical stability of the borehole sealing, significantly reduces the risk of grout leakage, and ensures construction safety.

[0030] The overall working principle of the device of the present invention is as follows: The mixing and storage component drives the mixing shaft 14 and the mixing blade 15 to rotate through the drive motor 13, and mixes the static crushing agent and water into a uniform slurry in the storage tank 11; the slurry delivery component draws the slurry in the storage tank 11 into the suction pipe 22 through the grouting pump 21, and then continuously delivers it to the inside of the blast hole 5 through the slurry delivery hose 23; the orifice sealing component wedges the orifice of the blast hole 5 with the anti-blowout plug 31 of the conical structure to prevent the slurry from overflowing; the self-locking clamping component pre-places the deep anchor 42 deep in the blast hole 5 before grouting, and establishes a pre-tension state through the flexible connecting cable 41 and the top locking member 43. After grouting, the deep anchor 42 is wrapped and anchored by the slurry. When the slurry expands and generates the orifice thrust, the self-locking clamping component uses the anchoring force of the deep anchor 42 to reverse the displacement of the anti-blowout plug 31, so as to achieve the self-locking sealing effect of anchoring with slurry and resisting blowout with anchor. The four components work together to complete a complete static explosive charging operation chain, which includes automatic mixing, rapid conveying, orifice sealing, and self-locking blowout prevention. The components support each other in function and structure and work synergistically to enhance each other's efficiency.

[0031] The present invention also provides a static blasting rapid charging method using the above-mentioned device, which specifically includes the following steps: S1. Install the cover plate 12 on the top of the slurry storage tank 11, and fix the drive motor 13, stirring shaft 14, and stirring blades 15 to the slurry storage tank 11. Specifically, fix the cover plate 12 to the top of the slurry storage tank 11 with bolts, fix the drive motor 13 to the upper surface of the cover plate 12, connect the output shaft of the drive motor 13 through the cover plate 12 to the stirring shaft 14, and fix the stirring blades 15 to the lower end of the stirring shaft 14. This step completes the assembly of the stirring and slurry storage assembly, preparing for subsequent automatic stirring operations.

[0032] S2. Securely connect the lower end of the flexible connecting cable 41 to the deep anchor 42, and pass the upper end of the flexible connecting cable 41 through the through hole 312 on the blowout stop plug 31. Then, insert the deep anchor 42 and the flexible connecting cable 41 together into the borehole 5. Install the blowout stop plug 31 at the borehole opening of the borehole 5, and manually or mechanically tighten the flexible connecting cable 41 upwards from outside the hole until it is in a straight tensioned state inside the hole. Then, use the top locking member 43 to lock and fix the flexible connecting cable 41 above the blowout stop plug 31. Next, pass the grout delivery hose 23 through the through hole 311 on the blowout stop plug 31 and extend it into the borehole 5. This step completes the pre-tensioning installation of the self-locking clamping assembly and the laying of the grout delivery hose 23, ensuring that the deep anchor 42 is pre-placed deep into the borehole 5, providing a structural basis for subsequent use of deep grout anchoring force to resist the ejection from the borehole opening.

[0033] S3. Add static fracturing agent and water into the slurry storage tank 11 through the feed inlet 121, start the drive motor 13 to drive the stirring shaft 14 and stirring blades 15 to rotate, and fully stir the slurry to make the static fracturing agent and water evenly mixed to form a slurry with good fluidity. This step realizes the mechanized automatic stirring of the static fracturing agent slurry.

[0034] S4. Start the grouting pump 21. The grouting pump 21 draws grout from the grout storage tank 11 through the grout suction pipe 22 and delivers it to the inside of the blast hole 5 through the grout delivery hose 23, so that the deep anchor 42 is completely submerged in the grout until the designed charge amount is reached. This step realizes the continuous and rapid delivery and filling of grout, while ensuring that the deep anchor 42 is completely wrapped by the grout.

[0035] S5. After grouting is completed, stop the grouting pump 21 and pull the grout delivery hose 23 out of the through hole 311. At this time, the opening of the blast hole 5 is blocked by the anti-blowout plug 31, and the self-locking clamping assembly is in the pre-tensioned working state.

[0036] The above steps are sequentially connected to achieve rapid, continuous, and safe charging of explosives in static blasting. Among them, the pre-tensioning installation of the self-locking clamping assembly in step S2 is a key step to ensure the subsequent blowout prevention effect. By pre-placing the deep anchor 42 deep into the blast hole and establishing a pre-tensioned state, the self-locking clamping assembly can immediately play its role once the grout begins to expand after grouting in step S4. The anchoring force of the deep anchor 42 restricts the displacement of the blowout preventer plug 31 without additional operation.

[0037] The following example, using the rock mass demolition construction of a certain project, illustrates the method of using this invention.

[0038] A project requires the demolition of rock masses in a reservoir area adjacent to residential buildings. To minimize the impact of construction vibration, noise, and flying rocks on the protected area and the normal lives of surrounding residents, static blasting is proposed for rock mass demolition. However, due to the tight project schedule, traditional manual mixing and manual charging methods are insufficient to meet the construction progress requirements. Therefore, the static blasting rapid charging device provided in this embodiment is used to improve the efficiency of static blasting charging. The specific construction process is as follows: First, install the cover plate 12 on top of the slurry storage tank 11, and fix the drive motor 13 to the upper surface of the cover plate 12, so that the output shaft of the drive motor 13 passes through the cover plate 12 and is coaxially connected to the stirring shaft 14. The stirring blade 15 is fixedly installed at the lower end of the stirring shaft 14. Fix the lower end of the flexible connecting cable 41 to the deep anchor 42, and pass the upper end through the wire hole 312. Then, insert the deep anchor 42 and the flexible connecting cable 41 into the blast hole 5 together. Press the anti-blowout plug 31 into the blast hole 5 to achieve initial sealing. Pull the flexible connecting cable 41 upwards outside the hole to a straight taut state, and use the top locking piece 43 to lock and fix it above the anti-blowout plug 31, so that it is in a pre-tensioned state. Finally, insert the slurry delivery hose 23 through the through hole 311 into the blast hole 5, and connect the slurry storage tank 11, the slurry suction pipe 22, the grouting pump 21 and the slurry delivery hose 23 in sequence.

[0039] Then, according to the ratio recommended in the instructions for static breaker, the static breaker and water are added to the slurry storage tank 11 through the feed inlet 121. The drive motor 13 is started to drive the stirring shaft 14 and stirring blades 15 to rotate, and the slurry is thoroughly stirred for about 5 minutes, so that the static breaker and water are evenly mixed to form a slurry with good fluidity.

[0040] Next, the grouting pump 21 is started to continuously deliver the well-mixed grout into the borehole 5, so that the deep anchor 42 is completely submerged in the grout until the borehole 5 reaches the designed charge amount.

[0041] Then, stop the grouting pump 21 and pull the grout delivery hose 23 out of the through hole 311 on the anti-blowout plug 31.

[0042] Finally, after the static fracturing agent has fully reacted, expansion pressure gradually forms inside borehole 5, causing cracks in the rock mass to appear and propagate, thus achieving rock mass fracturing. After fracturing is completed, the blowout stop plug 31 and the self-locking clamping assembly are removed, and the device is cleaned before it can be used for the next cycle of static blasting.

[0043] This invention achieves automatic mixing of static fracturing agent and water by setting up a mixing and storage assembly consisting of a drive motor, a mixing shaft, and mixing blades, reducing manual operation and improving the uniformity of slurry mixing and construction efficiency. By setting up a slurry delivery assembly consisting of a grouting pump, a slurry suction pipe, and a slurry delivery hose, it achieves rapid delivery and continuous filling of slurry, reducing labor intensity and improving the efficiency of static blasting charging. By setting up a blowout stopper with a conical structure, it achieves reliable sealing of the blast hole opening. In particular, by setting up a self-locking clamping assembly consisting of a flexible connecting cable, deep anchors, and a top locking component, the deep anchors, after being submerged in the slurry, utilize the deep anchoring force generated by the slurry expansion reaction to resist blowout from the opening, forming a unique "slurry-anchored, blowout-resistant" self-locking sealing mechanism. This significantly improves the mechanical stability of the opening sealing, reduces the risk of blasting and slurry ejection, and ensures construction safety. In summary, this invention achieves integrated functions of automatic mixing, rapid delivery, reliable sealing, and self-locking blowout prevention of static fracturing agent slurry, which has significant progress and practical value compared to existing technologies.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
