Description

Technical Field

[0001] This application relates to the field of water-stop curtain construction technology, and in particular to a high-pressure jet grouting pile water-stop curtain construction device. Background Technology

[0002] In fields such as water conservancy projects and deep foundation pit support, high-pressure jet grouting pile water-stop curtain technology is widely used due to its good seepage prevention and reinforcement effects. High-pressure jet grouting piles use a drilling rig to send the jet grouting pipe and nozzle to the designed elevation of the pile bottom. The high-pressure generating device makes the grout sprayed from the nozzle at high speed. While destroying the soil, the drill rod rotates and lifts, so that the grout and soil are fully mixed and formed into a columnar solidified body to reinforce the foundation. Its construction follows the process of drilling first and then spraying, then drilling down and spraying and lifting and mixing, to ensure that the grout-soil ratio and quality of each meter of pile meet the standards. However, when faced with complex strata such as pebble layers and sand layers along riverbanks, this technology has exposed significant problems. In traditional construction, equipment such as feed pumps are placed directly on the stratum surface, making it extremely inconvenient to adjust the position of high-pressure jet grouting piles, which seriously affects construction efficiency. At the same time, the cement slurry in the connecting pipe between the cement slurry and the jet grouting pipe is prone to hardening and clogging when left to stand, resulting in frequent pipe cleaning and maintenance, which further delays the construction period. To address the aforementioned issues, Chinese patent CN216948294U proposes integrating the feed pump and cement slurry mixing tank onto a base with casters, facilitating overall equipment movement and reducing the risk of pipeline blockage. However, this solution still has limitations: in the cement slurry transmission stage, when the slurry flows through complex pipe structures such as four-way pipes, there is a lack of additional power drive. Relying solely on the initial pressure of the feed pump is insufficient to ensure smooth flow of the cement slurry. Due to the complex internal structure of the four-way pipe and its high fluid resistance, the cement slurry is prone to solidify inside the pipe due to reduced flow rate, leading to blockage, construction interruption, and increased construction costs and management difficulty. It is evident that the existing technology has certain defects and shortcomings, thus requiring improved design. Summary of the Invention

[0014] In summary, this application includes the following beneficial technical effects: This equipment, by incorporating a mixing mechanism, effectively improves the stability of material feeding and the uniformity of mixing, achieving efficient integration of cement slurry mixing and conveying. During construction, after the cement slurry is injected into the tank through the feeding pipe, the second motor starts, driving the rotating shaft to rotate via the first synchronous pulley and synchronous belt. This drives the mixing frame and mixing plate to agitate the cement slurry in all directions, ensuring thorough mixing of all components. Simultaneously, the rotating shaft, in conjunction with the inner auger, conveys the cement slurry from the bottom upwards, forming a circulating flow and enhancing the mixing effect. After mixing is complete, the second motor reverses, driving the inner auger to push the cement slurry in the opposite direction. This, combined with the feeding pump, quickly and stably conveys the slurry to the three-way pipe, reducing construction stagnation caused by poor flow and improving overall construction efficiency. This device uses a transmission component and a material guiding component through precision gear transmission to enable the external auger to assist in the conveying of cement slurry in the three-way pipe. During operation, when the second motor is running, the power is transmitted through the synchronous wheel and hexagonal sleeve, driving the hexagonal support rod and the lower bevel gear to rotate, which in turn drives the upper bevel gear and the external auger to rotate. During the discharge process, the inner auger assists in feeding in the tank, while the outer auger continuously pushes the cement slurry to flow in the three-way pipe. To address the problem that the complex structure of the three-way pipe can easily lead to a slowdown in the flow rate of cement slurry and solidification blockage, the synchronous drive of the two augers forms a stable thrust, reduces fluid resistance, and ensures continuous and smooth cement slurry conveying. This device, by incorporating an auxiliary maintenance mechanism, further enhances the convenience of overall maintenance. During use, when cement slurry clumps inside the tank or the mixing components wear out, the operator starts the first motor. The lead screw rotates, causing the slider to slide along the vertical rail frame. The top cover is then removed from the top of the tank via the connecting arm, allowing the mixing mechanism to be extracted for cleaning and maintenance. The sliding sleeve structure of the hexagonal sleeve and hexagonal support rod ensures smooth displacement of the top cover while maintaining power transmission of the drive components, ensuring that the maintenance process is unaffected. This design significantly improves the convenience of equipment maintenance, extends the equipment's service life, and enhances its reliability. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0018] This application discloses a high-pressure jet grouting pile water-stop curtain construction device. For example... Figure 1-8 As shown, the system includes a base 1, a support frame 2 fixedly installed on one side of the top of the base 1, a tank 3 fixedly installed on the top of the support frame 2, a maintenance auxiliary mechanism 9 fixedly installed on the rear side of the top of the base 1 near the tank 3, a stirring mechanism 5 fixedly installed on the top of the maintenance auxiliary mechanism 9, the bottom of the stirring mechanism 5 extending into the interior of the tank 3, a material guiding mechanism 6 fixedly installed at the output end of the tank 3, the material guiding mechanism 6 and the stirring mechanism 5 being connected by a transmission, a water supply unit 7 and an air compressor unit 8 fixedly installed at both ends of the side of the base 1 away from the tank 3 respectively, both of the water supply unit 7 and the air compressor unit 8 being connected to the material guiding mechanism 6, a nozzle 4 fixedly installed at the output end of the material guiding mechanism 6, and a nozzle 10 fixedly installed at the output end of the nozzle 4. The material guiding mechanism 6 includes a connecting valve 61 and a material guiding assembly 62. The connecting valve 61 is fixedly installed at the bottom output end of the tank 3. A feeding pump 63 is fixedly installed at the output end of the connecting valve 61. A three-way pipe 64 is fixedly installed at the output end of the feeding pump 63.

The material guiding assembly 62 is fixedly installed in the middle of the side of the base 1 away from the tank 3. The end of the material guiding assembly 62 extends into the interior of the three-way pipe 64. The top of the material guiding assembly 62 is connected to the mixing mechanism 5. When this high-pressure jet grouting pile water-stop curtain construction device is working, the base 1 provides stable support for the whole, the support frame 2 stabilizes the tank 3, and the maintenance auxiliary mechanism 9 can assist in the operation of the mixing mechanism 5 during equipment maintenance. When cement slurry needs to be prepared, the mixing mechanism 5 is started to mix the materials in the tank 3. After mixing, the bottom connecting valve 61 of the tank 3 is opened, and the cement slurry is transported through the three-way pipe 64 under the action of the feeding pump 63. During this process, the material guiding component 62 is connected to the mixing mechanism 5, and the power of the mixing mechanism 5 is transmitted to the material guiding component 62, driving it to operate inside the three-way pipe 64, assisting in promoting the flow of cement slurry and ensuring smooth transportation. At the same time, the water supply unit 7 and the air compressor unit 8 supply water and air to the three-way pipe 64 respectively, which mix with the cement slurry in the three-way pipe 64 to form a mixed fluid that meets the construction requirements. Finally, the mixed fluid is sprayed out from the nozzle 10 through the nozzle 4 for the construction of high-pressure jet grouting pile water-stop curtain, realizing the reinforcement and water-stopping functions of complex strata.

[0019] Please refer to Figures 6-7The transmission assembly 55 includes a side plate 551, which is fixedly installed on one side of the top cover 51. A second synchronous pulley 552 is rotatably connected to the top outer end of the side plate 551. The second synchronous pulley 552 is connected to the first synchronous pulley 523 via a synchronous belt. A linkage group 553 is rotatably connected to the bottom outer end of the side plate 551. The linkage group 553 includes a hexagonal sleeve 5531. A hexagonal support rod 5532 is slidably connected inside the hexagonal sleeve 5531. A lower bevel gear 5533 is fixedly installed at the bottom of the hexagonal support rod 5532. The lower bevel gear 5533 is connected to the material guide assembly 62. The lower end of the hexagonal support rod 5532 is rotatably connected to the material guide assembly. Inside the outer end of 62, the material guiding assembly 62 includes a protective shell 621 and an outer auger 622. A fixing frame 623 is fixedly installed at the upper inner end of the protective shell 621. A hexagonal support rod 5532 is rotatably connected to the upper inner side of the fixing frame 623. The outer auger 622 is rotatably connected to the inside of a three-way pipe 64. A shaft 624 is fixedly installed at the outer end of the outer auger 622. The shaft 624 and the three-way pipe 64 are rotatably connected. An upper bevel gear 625 is fixedly installed at the outer end of the shaft 624 through the three-way pipe 64. The upper bevel gear 625 and the lower bevel gear 5533 are connected in a transmission relationship. Fixing seats 14 are fixedly connected at the four corners of the bottom of the base 1. A caster wheel 11 is rotatably connected to the bottom. A side frame 12 is fixedly installed on the outside of the fixed base 14. A self-locking screw 13 is threaded to the outer end of the side frame 12. The self-locking screw 13 is a hand-tightening screw. During the use of this device, the transmission component 55 and the material guiding component 62 work together to realize power transmission and auxiliary conveying of cement slurry. At the same time, the equipment has flexible movement and positioning capabilities. When the first synchronous wheel 523 of the drive component 52 rotates, it drives the second synchronous wheel 552 on the top of the side plate 551 to rotate through the synchronous belt. The second synchronous wheel 552 drives the hexagonal sleeve 5531 of the linkage group 553 to rotate. Due to the slip between the hexagonal sleeve 5531 and the hexagonal support rod 5532... With a dynamic connection and matching cross-section, the hexagonal support rod 5532 rotates synchronously. The lower bevel gear 5533 at its bottom meshes with the upper bevel gear 625 of the material guide assembly 62, which is fixed to the end of the shaft 624. The shaft 624 drives the external auger 622 inside the three-way pipe 64 to rotate, thereby assisting in pushing the cement slurry and reducing flow resistance. When the equipment moves, the universal wheels 11 at the four corners of the base 1 provide support and facilitate turning. After reaching the designated position, the operator manually rotates the self-locking screw 13 at the outer end of the side frame 12 to press its lower end against the ground. The self-locking function of the screw is used to fix the equipment, prevent displacement during construction, and ensure operational stability.

[0020] Please refer to Figures 3-7The drive assembly 52 includes a base frame 521, which is fixedly installed in the middle of the top of the top cover 51. A second motor 522 is fixedly connected to the top of the base frame 521. A first synchronous pulley 523 is fixedly installed through the base frame 521 at the output end of the second motor 522. The first synchronous pulley 523 is connected to the transmission assembly 55. The bottom of the first synchronous pulley 523 is connected to the top of the agitation assembly 53. The agitation assembly 53 includes a rotating shaft 531, which is rotatably connected to the bottom of the top cover 51. The outer surface of the rotating shaft 531 is evenly spaced. A mixing frame 532 is fixedly installed. Mixing plates 533 are fixedly connected to the inner side of the mixing frame 532 in a linear arrangement at equal intervals. The top of the rotating shaft 531 is connected to the bottom of the first synchronous pulley 523. An inner auger 534 is fixedly installed at the bottom of the rotating shaft 531, extending into the bottom of the tank body 3. The bottom of the tank body 3 and the inner auger 534 are arranged in a conical shape. The drive assembly 52 and the agitator assembly 53 work together to achieve efficient mixing and auxiliary conveying of cement slurry. During use, the second motor 522 is installed on the base frame 52. 1. At the top, after the second motor 522 is started, its output end drives the first synchronous pulley 523 to rotate at high speed. The first synchronous pulley 523 transmits power to the transmission component 55 on one hand, providing auxiliary driving force for the material guiding component 62; on the other hand, it drives the rotating shaft 531 to rotate. The rotating shaft 531 penetrates the top cover 51 and extends into the tank 3. As the rotating shaft 531 rotates, the stirring frame 532 on its outer surface and the stirring plate 533 on its inner side rotate accordingly, stirring the cement slurry in the tank 3 from multiple angles and in all directions to ensure that all components are fully mixed. At the same time, the bottom of the rotating shaft 531... The inner auger 534 operates synchronously. Since the bottom of the tank 3 and the inner auger 534 are conical in shape, the inner auger 534 can effectively transport the cement slurry from the bottom of the tank 3 to the top, so that the cement slurry rises and falls naturally, forming an up-and-down circulation. This circulation, in conjunction with the stirring of the mixing frame 532 and the mixing plate 533, significantly improves the uniformity of cement slurry mixing. After the mixing is completed, the inner auger 534 can also push the cement slurry from the top to the bottom when the motor reverses, assisting the cement slurry to be discharged from the tank 3 and providing power support for subsequent conveying.

[0021] Please refer to Figures 1-4The maintenance auxiliary mechanism 9 includes a vertical rail frame 91, which is fixedly installed on the rear side of the base 1 near the tank body 3. A first motor 92 is fixedly installed at the bottom of the vertical rail frame 91. A lead screw 93 is fixedly installed through the output end of the first motor 92 and is rotatably connected to the interior of the vertical rail frame 91. A slider 94 is threadedly connected to the outer surface of the lead screw 93 and is slidably connected to the interior of the vertical rail frame 91. A connecting arm 95 is fixedly installed at the top of the slider 94. The outer end of the connecting arm 95 is connected to the top of the stirring mechanism 5. The stirring mechanism 5 includes a top cover 51, which is fixedly installed on the top of the connecting arm 95. A drive assembly 52 is provided on the top of the top cover 51, and an agitator 53 is rotatably connected to the bottom of the top cover 51. The top cover 51 covers the top of the tank 3. The main body of the agitator 53 extends into the interior of the tank 3. A transmission assembly 55 is provided at the outer end of the drive assembly 52, and the bottom of the transmission assembly 55 is drively connected to the outer end of the material guide assembly 62. A feeding pipe 54 is fixedly installed on one side of the top of the top cover 51. When the equipment needs maintenance, the first motor 92 at the bottom of the vertical rail frame 91 is started, and its output end drives the lead screw 93 to rotate. The lead screw 93 causes the slider 94 to slide up and down along the guide rail inside the vertical rail frame 91 through thread transmission. Since the top connecting arm 95 of the slider 94 is connected to the top cover 51 of the stirring mechanism 5, the movement of the slider 94 drives the top cover 51 to rise or fall. When the top cover 51 is removed from the top of the tank 3, the stirring component 5 of the stirring mechanism 5 can be moved. 3. The mixing mechanism 5 is pulled out from inside the tank 3 for easy cleaning and maintenance. During normal construction, the mixing mechanism 5 is driven by the drive component 52 to rotate the bottom stirring component 53 inside the tank 3 to mix the cement slurry. At the same time, the transmission component 55 at the outer end of the drive component 52 is connected to the material guiding component 62 to transmit power to the material guiding component 62 and assist in promoting the flow of the cement slurry during the conveying process. The feeding pipe 54 is used to add materials to the tank 3 to provide raw materials for the mixing operation and ensure continuous construction.

[0022] The implementation principle of the high-pressure jet grouting pile water-stop curtain construction device in this application embodiment is as follows: During the application of this equipment, after the construction personnel inject cement slurry into the tank 3 through the feeding pipe 54, the second motor 522 starts to run. The output shaft of the second motor 522 is closely connected to the first synchronous pulley 523. As the second motor 522 rotates, the first synchronous pulley 523 obtains power and rotates at high speed. The first synchronous pulley 523 transmits power to the rotating shaft 531 through the synchronous belt, causing the rotating shaft 531 to start rotating inside the mixing frame 532. The mixing frame 532 and the rotating shaft 531 adopt a special connection structure. When the rotating shaft 531 rotates, it can drive the mixing frame 532 to produce corresponding movement. At the same time, the internal components of the mixing frame 532... The mixing plate 533 also stirs, and the mixing plate 533 can stir the cement slurry inside the tank 3 in all directions during the rotation, ensuring that the components of the cement slurry are fully in contact. At the same time, the rotating shaft 531 will also drive the inner auger 534 to rotate synchronously during the rotation. The inner auger 534 is vertically installed inside the tank 3 and can effectively transport the cement slurry at the bottom of the tank 3 from bottom to top. When the cement slurry is transported to the upper part of the tank 3, it will automatically fall down due to the loss of upward thrust, forming an up-and-down circulating flow state. This flow state, combined with the stirring action of the mixing frame 532 and the mixing plate 533, allows the cement slurry to be more fully mixed in the tank 3, greatly improving the mixing uniformity. When the cement slurry is mixed and needs to be discharged from tank 3 for the next construction step, the operator first opens the connecting valve 61 at the bottom of tank 3 to provide a channel for the cement slurry to flow out. Then, the second motor 522 is rotated in reverse. At this time, the rotating shaft 531 drives the inner auger 534 to reverse. The inner auger 534 in the reverse state changes the conveying direction of the cement slurry, conveying the cement slurry located at the top of tank 3 from top to bottom, so that it flows quickly to the outlet of tank 3. At this time, the feed pump 63 is started. The suction force generated by the feed pump 63 and the pushing force of the inner auger 534 work together to quickly and stably convey the cement slurry inside tank 3 into the three-way pipe 64. This design not only realizes the efficient mixing of cement slurry, but also provides auxiliary conveying power for the feed pump 63, effectively improving the stability of the cement slurry fluid flow and reducing construction delays caused by poor cement slurry flow. The coordinated operation of the transmission component 55 and the material guiding component 62 further improves the conveying performance of cement slurry in the three-way pipe 64. When the second motor 522 starts running, its power is first transmitted to the first synchronous pulley 523. The first synchronous pulley 523 drives the second synchronous pulley 552 to rotate through the synchronous belt. The second synchronous pulley 552 is fixedly connected to the hexagonal sleeve 5531. Therefore, when the second synchronous pulley 552 rotates, the hexagonal sleeve 5531 will also rotate synchronously. The hexagonal sleeve 5531 has a special sliding groove structure inside, which matches the outer surface of the hexagonal support rod 5532, so that the hexagonal support rod 5532 can slide inside the hexagonal sleeve 5531 and rotate with it. A lower bevel gear 5533 is installed at the bottom of the hexagonal support rod 5532. When the hexagonal support rod 5532 rotates, the lower bevel gear 5533 also rotates. The lower bevel gear 5533 meshes with the upper bevel gear 625. Through the gear transmission principle, the rotation of the lower bevel gear 5533 will drive the upper bevel gear 625 to rotate. A connecting shaft is connected to the outside of the upper bevel gear 625. The other end of the connecting shaft is fixedly connected to the outer auger 622. Therefore, the rotation of the upper bevel gear 625 can drive the connecting shaft to rotate, thereby driving the outer auger 622 to rotate inside the three-way pipe 64. During the material discharge process, the inner auger 534 assists the feed pump 63 in the tank 3 to transport cement slurry to the three-way pipe 64, while the outer auger 622 further promotes the flow of cement slurry inside the three-way pipe 64. The internal structure of the three-way pipe 64 is complex. In traditional construction, the flow rate of cement slurry in the pipe is easily slowed down or even solidified. However, this equipment can provide a continuous and stable driving force for cement slurry through the synchronous drive of the inner auger 534 and the outer auger 622, which effectively reduces the flow resistance of cement slurry in the three-way pipe 64 and ensures that cement slurry can flow smoothly inside the three-way pipe 64. This avoids the situation where cement slurry solidifies and blocks the pipe due to slow flow rate, and greatly improves the continuity and stability of cement slurry transportation process. To facilitate daily maintenance and repair of the equipment, this equipment is also equipped with a maintenance auxiliary mechanism 9. After long-term operation of the equipment, some cement slurry may remain inside the tank 3, and the components of the mixing mechanism 5 may also wear out. At this time, it is necessary to carry out maintenance and repair of the equipment. When maintenance is required, the operator starts the first motor 92. The power output shaft of the first motor 92 is connected to the lead screw 93. As the motor runs, the lead screw 93 starts to rotate. The lead screw 93 is connected to the slider 94 inside the vertical rail frame 91 by a thread. When the lead screw 93 rotates, the slider 94 will slide along the guide rail inside the vertical rail frame 91. The slider 94 is fixedly connected to the connecting arm 95, so the sliding of the slider 94 can drive the connecting arm 95 to move. The other end of the connecting arm 95 is connected to the top cover 51. Under the drive of the connecting arm 95, the top cover 51 can be removed from the top of the tank 3. When the top cover 51 is removed, the stirring mechanism 5 is fully exposed. At this time, the operator can easily pull the stirring mechanism 5 out of the tank 3 and carry out a comprehensive cleaning and maintenance of the inside of the tank 3 and the various parts of the stirring mechanism 5. During the telescopic movement of the top cover 51, the special sleeve structure of the hexagonal sleeve 5531 and the hexagonal support rod 5532 plays an important role. Because the hexagonal sleeve 5531 and the hexagonal support rod 5532 are interlocked and can slide, they can ensure the smooth movement of the top cover 51 while maintaining the power transmission of the lower bevel gear 5533 when the top cover 51 moves up and down. This allows the transmission component 55 to continue to work normally without being affected by the movement of the top cover 51. This design ensures the efficiency and convenience of the maintenance process, meets the actual needs of daily equipment maintenance, effectively extends the service life of the equipment, and improves the overall convenience and reliability of the equipment.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
