Description

Technical Field

[0001] This invention relates to the field of concrete pouring technology, specifically to a concrete pouring device for karst pile hole pouring. Background Technology

[0002] In order to effectively ensure the construction quality of the bored piles and prevent insufficient bearing capacity of the pile foundation due to excessive grout at the top, it is usually necessary to perform over-grouting to a certain height during the construction of bored piles for highway bridges.

[0003] Due to the complex and concealed construction environment of bored piles, it is difficult to control the over-pouring height during the actual grouting process. It is very easy for the over-pouring height to be insufficient or excessive, which seriously reduces the quality of pile formation and affects the overall bearing capacity of the pile foundation.

[0004] In the construction of cast-in-place piles in karst areas, concrete is easily lost in large quantities through unexplored karst caves, fissures, or soil cavities. However, in traditional construction, the visibility of the inside of the hole is poor. It is dangerous for workers to observe around the karst pile hole. Moreover, relying solely on manual experience to judge whether the concrete interface position has reached the standard results in a large error. It is impossible to accurately control the pouring height. Construction workers cannot detect abnormal concrete loss in time, which leads to an inexplicable drop in the pile top elevation and even a serious quality accident such as "pile breakage".

[0013] Preferably, a plurality of fixed bending rods are fixedly installed on the outside of the guide bend, and a supporting round frame is fixedly connected between the plurality of fixed bending rods. A rotating frame is sleeved on the outside of the supporting round frame, the outer diameter of the rotating frame being larger than the outer diameter of the guide bend, and the rotating frame being disposed on the outside of the cable.

[0014] Preferably, the support frame has a second mounting slot and two first mounting slots on one side, and the two electromagnets are respectively disposed inside the two first mounting slots.

No bolt tightening or welding is required. The camera can be quickly installed and removed according to construction needs, which reduces the mutual wear between the camera and the concrete pouring pipe when not in operation, greatly improves the installation and removal efficiency, and reduces the maintenance cost of the equipment.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: Figures 1-8 As shown, the present invention provides a concrete pouring device for karst pile hole grouting, including a concrete pouring pipe 32 and a support platform 1. A connecting component is installed at the bottom of the support platform 1, and a support frame 10 is connected to the end of the connecting component. Two electromagnets 12 are fixedly installed on one side of the support frame 10. A positioning component is provided on one side of the support frame 10. An external threaded part 33 is provided inside the positioning component. Multiple cameras 5 are installed on the top of the positioning component.

[0022] Specifically, such as Figure 1 and Figure 2 The external threaded part 33 is fixedly installed on the outside of the concrete pouring pipe 32. The concrete pouring pipe 32 passes through the support platform 1 and is used to transport concrete.

[0023] Multiple support wheels 2 are fixedly installed inside the support platform 1. The multiple support wheels 2 are equidistantly distributed on a circular track. The inner diameter of the circular channel formed by the multiple support wheels 2 is larger than the outer diameter of the external threaded part 33, so that the concrete pouring pipe 32 and the external threaded part 33 can pass smoothly through the inside of the circular channel. The multiple support wheels 2 are all set on the outside of the concrete pouring pipe 32. Multiple support rods 3 are fixedly connected to the bottom of the support platform 1. The bottom of the support platform 1 supported by the multiple support rods 3 has sufficient operating space.

[0024] Specifically, such as Figure 1 , Figure 3 , Figure 6 and Figure 2The mounting box 21 in the connecting assembly is fixedly installed at the bottom of the support platform 1. The forward and reverse motor 24 and the gearbox 25 are fixedly installed inside the mounting box 21. The output end of the forward and reverse motor 24 is fixedly connected to the input end of the gearbox 25. The winding frame 23, which is fixedly connected to the output end of the gearbox 25, is rotatably installed inside the mounting box 21. Therefore, the forward and reverse motor 24 is controlled to work, and the forward and reverse motor 24 drives the winding frame 23 to rotate through the gearbox 25. The forward and reverse motor 24 is controlled to work in the forward or reverse direction, and the winding frame 23 rotates clockwise or counterclockwise.

[0025] A metal ring 30 is installed inside the mounting slot 29 on one side of the winding frame 23. The metal ring 30 is fixedly connected to the winding frame 23. An electromagnet 31 is fixedly installed inside the mounting box 21 on one side of the metal ring 30. The winding frame 23 drives the metal ring 30 to rotate. When the forward and reverse motor 24 stops working, the electromagnet 31 works to attract and fix the metal ring 30 through magnetic force. The metal ring 30 is fixed, and the winding frame 23 is fixed.

[0026] A fixed conductive ring 28 is rotatably mounted on the outside of a movable conductive ring 27 fixedly connected to the other side of the winding frame 23. The fixed conductive ring 28 is fixedly installed inside the mounting box 21. The rotation of the movable conductive ring 27 will not affect the connection between the movable conductive ring 27 and the fixed conductive ring 28. A cable 15 is fixedly connected inside the movable conductive ring 27. A circular groove 26 is opened on one side of the winding frame 23. One end of the cable 15 passes through the circular groove 26 and the mounting box 21 and extends to the outside of the mounting box 21. The cable 15 is fixedly connected to the winding frame 23, and part of the cable 15 is wrapped around the outside of the winding frame 23. When the winding frame 23 rotates clockwise or counterclockwise, the winding frame 23 winds up or unwinds the cable 15. One end of the cable 15 rotates synchronously with the winding frame 23 and the movable conductive ring 27. The cable 15 is connected to the power supply through the movable conductive ring 27 and the fixed conductive ring 28.

[0027] The cable 15 is provided with rollers 22 and guide bends 16 on the outside. The rollers 22 are fixedly installed on the top of the inner cavity of the mounting box 21. The guide bends 16 are located on the outside of the mounting box 21 and are fixedly connected to the support platform 1. There are two fixed vertical plates 17. The rollers 22 and guide bends 16 work together to guide the cable 15 in a different direction, reducing the wear and tear on the cable 15. One end of the cable 15 is fixedly connected to the support frame 10 with a socket 14. The socket 14 moves synchronously with the support frame 10.

[0028] A support frame 20 is fixedly connected between multiple fixed bending rods 19 fixedly installed on the outside of the guide bend 16. The outer diameter of the rotating frame 18 sleeved on the outside of the support frame 20 is larger than the outer diameter of the guide bend 16. The rotating frame 18 is set on the outside of the cable 15 and can rotate on the outside of the support frame 20. When the socket 14 where the cable 15 is fixed is subjected to force, causing the cable 15 to sway and change direction, the cable 15 will transfer the force to the rotating frame 18, which can rotate, thereby reducing the wear rate of the cable 15.

[0029] Therefore, the forward and reverse motors 24 in the control connection assembly work to make the winding frame 23 wind up or unwind the cable 15. One end of the cable 15 is fixedly connected to the support frame 10 through the socket 14, which can move up and down. The cable 15 is kept connected to the power supply under the action of the moving conductive ring 27 and the fixed conductive ring 28.

[0030] Specifically, such as Figure 4 The support frame 10 has a mounting groove 2 13 and two mounting grooves 11 on one side. Two electromagnets 2 12 are respectively set inside the two mounting grooves 11. The outer wall of the electromagnets 2 12 is fixedly connected to the support frame 10. The mounting groove 2 13 is set on one side of the socket 14. Both the support frame 10 and the electromagnets 2 12 are set as curved surfaces. The support frame 10 can fit tightly against the outer wall of the internal threaded part 8.

[0031] Specifically, such as Figure 2 and Figure 3 In the positioning component, multiple cameras 5 are fixedly connected to the bottom of the mounting plate 4. The multiple cameras 5 are equidistantly distributed on a circular track. The internal threaded part 8 fixedly connected to the top of the mounting plate 4 can be threaded onto the outside of the external threaded part 33. An electromagnet 6 is set inside the mounting groove 4 34 opened inside the internal threaded part 8. The outer wall of the electromagnet 6 is fixedly connected to the internal threaded part 8. The electromagnet 6 works by magnetically attracting and fixing the external threaded part 33, further increasing the firmness of the connection between the internal threaded part 8 and the external threaded part 33, and preventing the internal threaded part 8 from detaching from the external threaded part 33 during the movement of the external threaded part 33 and the concrete pouring pipe 32.

[0032] The plug 9 and two metal rings 7 are fixedly installed on the outside of the internal threaded part 8. The plug 9 can pass through the mounting groove 13 and be inserted into the socket 14.

[0033] In summary, the pouring auxiliary equipment consists of a support platform 1, a connecting component, a support frame 10, two electromagnets 12, a positioning component, an external threaded component 33, and multiple cameras 5. The connection between the pouring auxiliary equipment and the human-machine interaction device is an existing technology and will not be elaborated here.

[0034] The working principle of the pouring auxiliary equipment is as follows: The support platform 1 is installed on the ground or building via the support rod 3 (by placing a weight or pre-drilling a mounting hole), so that the support platform 1 is installed on the top of the karst pile hole, thus completing the fixation of the pouring auxiliary equipment.

[0035] Subsequently, the concrete pouring pipe 32 is passed through the support platform 1 from top to bottom. After the concrete pouring pipe 32 moves to the bottom of the support platform 1, the operation of the concrete pouring pipe 32 is paused. Then, the internal threaded part 8 is rotated and installed on the outside of the external threaded part 33, and the internal threaded part 8 is rotated so that the plug 9 is roughly facing the support frame 10. The camera 5, which is fixedly connected to the bottom of the internal threaded part 8, is installed on the outside of the concrete pouring pipe 32.

[0036] Subsequently, the support frame 10 with the mounting slot 2 13 is fitted onto the outside of the plug 9. The position of the support frame 10 is controlled so that the two electromagnets 2 12 are close to the two metal rings 7. The bottom of the support frame 10 abuts against the mounting plate 4. Then, the staff controls the operation of the electromagnet 6 and the two electromagnets 2 12 through the human-machine interface. The operation of the electromagnet 6 uses magnetic attraction to fix the external threaded part 33, increasing the firmness of the connection between the internal threaded part 8 and the external threaded part 33. The operation of the electromagnets 2 12 uses magnetic attraction to fix the metal ring 7, so that the support frame 10 is installed on the outside of the internal threaded part 8 by the two electromagnets 2 12. This completes the complete fixing and power supply of multiple cameras 5, allowing the cameras 5 to be quickly and conveniently installed on the outside of the concrete pouring pipe 32. The cameras 5 can be disassembled as needed, reducing mutual damage between the cameras 5 and the concrete pouring pipe 32 during non-operational periods.

[0037] Subsequently, the concrete pouring pipe 32 moves into the karst pile hole. At the same time, the forward and reverse motors 24 are controlled to work in reverse. The forward and reverse motors 24 drive the winding frame 23 to rotate through the gearbox 25. The winding frame 23 rotates counterclockwise and unwinds the cable 15. One end of the cable 15 rotates synchronously with the winding frame 23 and the moving conductive ring 27. The cable 15 is connected to the power supply through the moving conductive ring 27 and the fixed conductive ring 28. After the cable 15 is unwound, the support frame 10 fixedly connected to one end moves synchronously with the concrete pouring pipe 32. After a period of rapid unwinding of the cable 15, the cable 15 is unwound at a uniform speed, so that the unwound part of the cable 15 has sufficient allowance. The shaking of the concrete pouring pipe 32 will not exert force on the connection position between the cable 15 and the socket 14. The cable 15 stably provides power to the electromagnet 12, the electromagnet 6 and multiple cameras 5 through the socket 14 and the plug 9. The unwinding and winding of the cable 15 is only for the storage of the cable 15. The up and down movement of the concrete pouring pipe 32 is controlled by other equipment.

[0038] Subsequently, concrete is poured into the karst pile hole through the concrete pouring pipe 32. As the concrete pouring time changes, the concrete pouring pipe 32 gradually moves upward. At the same time, the forward and reverse motors 24 are controlled to rotate forward, and the cable 15 is wound up. Finally, the concrete pouring pipe 32 leaves the inside of the karst pile hole, completing the karst pile hole pouring work. During this process, multiple cameras 5 work. The cameras 5 capture the upward movement of the concrete liquid level inside the karst pile hole. The cameras 5 are connected to the human-machine interaction device through wireless communication technology. The capture results of the cameras 5 are fed back to the human-machine interaction device. Based on the capture results of the cameras 5, the staff can promptly detect abnormal concrete loss and promptly detect the large amount of concrete flowing away during the karst pile hole pouring process due to unexplored karst caves, fissures or soil cavities. This can prevent concrete from flowing into the surrounding karst caves or fissures, causing the pile top elevation to drop for no reason without timely detection. It can also effectively prevent the pile body concrete discontinuity caused by accidental concrete loss, resulting in a serious quality accident of "broken pile".

[0039] In summary, this application, by installing multiple cameras 5 on the outside of the concrete pouring pipe 32 that can rise and fall synchronously with the pipe, captures real-time images of the concrete level rising inside the karst pile hole during the pouring process and wirelessly transmits the images to a ground-based human-machine interface device. This allows construction personnel to promptly detect abnormal concrete loss caused by unexplored karst caves, fissures, or soil cavities, effectively preventing unexplained drops in pile top elevation and "pile breakage" quality accidents caused by discontinuities in the pile body concrete. It achieves visualized monitoring of the pouring process and significantly improves the quality controllability of cast-in-place pile construction in karst areas.

[0040] The camera 5 assembly is quickly installed and securely positioned by the threaded engagement of the internal threaded part 8 and the external threaded part 33, and by the double locking structure of the external threaded part 33 magnetically attracted and fixed by the electromagnet 6. At the same time, the metal ring 7 is magnetically attracted and fixed by the electromagnet 12 on the support frame 10, thus completing the power supply connection between the camera 5 and the socket 14 and plug 9. No bolt tightening or welding is required. The camera 5 can be quickly assembled and disassembled according to construction needs, which reduces the mutual wear between the camera 5 and the concrete pouring pipe 32 when not in operation, and greatly improves the assembly and disassembly efficiency and reduces the maintenance cost of the equipment.

[0041] The forward and reverse motors 24 and the gearbox 25 drive the winding frame 23 to actively wind up and unwind the cable 15. The cable 15 is guided by multiple rollers 22, guide bends 16 and rotatable rotating frames 18, ensuring that the cable 15 has sufficient allowance during unwinding, effectively isolating the tension generated by the shaking of the concrete pouring pipe 32, and preventing the cable 15 from loosening at the connection with the socket 14. At the same time, the cooperation between the moving conductive ring 27 and the fixed conductive ring 28 ensures that the cable 15 maintains power supply throughout the winding and unwinding process, realizing stable power supply for the camera 5 and electromagnets 6 and 12 during the lifting and lowering process with the pipe, and ensuring the continuous and reliable operation of the monitoring system.

[0042] The support platform 1, connecting components, camera 5, and positioning components, including internal threaded parts 8 and mounting plates 4, are all detachable and reusable. One set of equipment can serve the grouting construction of multiple pile holes in succession, resulting in low amortization costs. At the same time, the camera 5 accurately monitors the concrete level, enabling on-demand pouring and avoiding excessive over-pouring as a "safety measure" in traditional construction, thus saving on concrete material costs. More importantly, by providing early warning of concrete loss, it avoids the huge economic losses caused by the scrapping of the entire pile and reconstruction due to pile breakage, demonstrating outstanding overall economic efficiency.

[0043] By integrating visual monitoring functions into the concrete pouring pipe 32, the grouting construction and quality monitoring are carried out simultaneously. This changes the passive mode of relying on manual experience or post-construction inspection in traditional construction, and moves the quality control point forward to the grouting process itself. This is groundbreaking in the field of karst pile hole grouting and provides a reliable technical solution for deep foundation construction under similar complex geological conditions.

[0044] 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 its spirit or essential characteristics. 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, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
