Description

Technical Field

[0001] This application relates to the field of pile foundation construction, and in particular to an integrated grouting device and its method of use. Background Technology

[0002] Post-grouting technology can significantly improve the bearing capacity of the foundation, thus achieving the expected bearing effect even with small pile diameters, short pile lengths, and a small number of piles. Therefore, it is widely used. Currently, a fixed mixing plant is usually set up on the construction site to produce concrete mortar. Subsequently, the concrete mortar in the mixing plant is transported to the foundation piles within the radiation range of the fixed mixing plant by a mortar pump, thereby realizing the grouting operation.

[0003] However, the use of fixed mixing plants means that after grouting is completed, the foundation piles within the range of the fixed mixing plant need to be moved to the next target area for grouting. This requires disassembling and relocating the fixed mixing plant, which wastes time. Especially in bridge construction, where the overall construction route is long and the work area is wide, the repeated disassembly and relocation of the fixed mixing plant will affect the grouting efficiency of the entire construction process. At the same time, existing fixed mixing plants usually only serve to mix cement, sand and water. If lumps appear in the cement or sand added to the fixed mixing plant, the mixing time is often extended to ensure the quality of the concrete mortar. This allows the lumps of cement and sand to be broken up and fully mixed with water, which also reduces the grouting efficiency. Summary of the Invention

[0004] In order to improve grouting efficiency, firstly, this application provides an integrated grouting device.

[0005] The integrated grouting equipment provided in this application adopts the following technical solution:

[0006] The device includes a mobile unit, a pulping assembly, and a grouting assembly. The pulping assembly includes a water storage container, a material storage container, and a pulping container. The pulping container is mounted on the mobile unit and connected to the grouting assembly. The water storage container is mounted on the mobile unit and connected to the pulping container. The material storage container is mounted on the mobile unit and is located above the pulping container and has a discharge port connected to the pulping container. The material storage container is equipped with a material crushing assembly for crushing lumpy materials. The pulping container is equipped with a stirring and scraping assembly.

[0007] By adopting the above technical solution, the water storage container stores clean water, while the material storage container contains a mixture of cement and sand. When slurry preparation is required, the water storage container delivers clean water to the slurry preparation container, and the cement and sand mixture in the material storage container is simultaneously delivered to the slurry preparation container. The mixture is then mixed with the clean water in the slurry preparation container, and stirred by the mixing and scraping components. This ensures that the cement and sand mixture is fully mixed with the clean water to prepare concrete mortar. Furthermore, since the water storage container, material storage container, and slurry preparation container are all mounted on a mobile device, slurry preparation can be carried out during the movement process, saving the time required to fix and restart the fixed mixing plant after transportation. In addition, the material crushing component can crush any lumps in the cement and sand mixture in the material storage container when it enters the slurry preparation container, allowing it to mix quickly with the clean water upon entering the slurry preparation container. This improves the slurry preparation efficiency and thus enhances the subsequent grouting efficiency.

[0008] Optionally, the material crushing assembly includes a lifting component, a mounting plate, a drive component, a rotating rod, and a crushing disc. The lifting component is installed on the top of the storage container and connected to the mounting plate. The drive component is installed on the side of the mounting plate away from the lifting rod. One end of the rotating rod is connected to the drive component, and the other end of the rotating rod is located inside the storage container and connected to the crushing disc. A material channel is formed between the end of the crushing disc away from the rotating rod and the inner wall of the bottom of the discharge container. The material channel gradually narrows from the direction away from the axis of the rotating rod towards the axis of the rotating rod.

[0009] By adopting the above technical solution, when the material formed by mixing cement and sand is put into the storage tank, it will first contact the side of the crushing disc near the rotating rod. Under the action of the driving component, the rotating rod drives the crushing disc to rotate around its own axis. The material accumulates from the material channel to the discharge port. During the accumulation process, since the material channel gradually narrows from the direction away from the axis of the rotating rod to the direction closer to the rotating rod, when the material clumps and blocks the material channel, as the crushing disc rotates, it not only squeezes the clumps but also makes the clumps tend to roll with the rotation of the crushing disc, thereby playing a role in crushing the material. The lifting component allows the crushing disc to rise, thereby increasing the space in the material channel. This can increase the speed at which the material converges to the discharge port and allow larger clumps to enter the material channel and be broken up as the crushing disc rotates. It can also lower the crushing disc, thereby reducing the space in the material channel, allowing the more solid clumps to be further squeezed and then converge to the discharge port after being broken up.

[0010] Optionally, the crushing disc includes a connecting part and a crushing part. The connecting part is fixedly connected to the rotating rod. A material channel is formed between the outer wall of the crushing part and the inner wall of the bottom of the storage container. The outer diameter of the connecting part gradually increases from the direction away from the discharge port to the direction closer to the rotating rod. A filter hole is provided on the connecting part. The filter hole passes through the connecting part and the crushing part and communicates with the material channel.

[0011] By adopting the above technical solution, filter holes are provided on the connecting part, so that fine particles in the material can be directly gathered at the discharge port through the filter holes without going through the material channel, which increases the speed at which the material gathers at the discharge port. At the same time, in conjunction with the rotation of the crushing disc, the agglomerated material will not be blocked at the filter holes.

[0012] Optionally, the outer wall of the grinding section is provided with multiple grinding teeth, which are distributed circumferentially around the axis of the rotating rod on the outer wall of the grinding section.

[0013] By adopting the above technical solution, the grinding teeth enable the agglomerated material to be broken up relatively quickly after being contacted by the crushing disc in the material channel.

[0014] Optionally, a telescopic cover is provided on the side of the mounting plate away from the drive component. The telescopic cover is fitted onto the rotating rod, and the end of the telescopic cover away from the mounting plate is connected to the outer wall of the storage container.

[0015] By adopting the above technical solution, the telescopic cover is located between the mounting plate and the storage container, so that when the lifting component is raising or lowering the mounting plate, the telescopic cover can always cover the rotating rod, preventing external dust from adhering to the rotating rod and ensuring the cleanliness of the rotating rod. It also prevents external dust from entering the storage container, and at the same time, it prevents the material dust in the storage container from escaping when the crushing disc rotates, thus achieving the effect of keeping the construction clean.

[0016] Optionally, the slurry container is equipped with a slurry outlet pipe, which is connected to the grouting assembly. The grouting assembly includes a tee connector, a grouting pipe, and a slurry discharge pipe. One end of the tee connector is connected to the slurry outlet pipe, and the other two ends of the tee connector are connected to the grouting pipe and the slurry discharge pipe, respectively. Valves are provided on the slurry outlet pipe, the grouting pipe, and the slurry discharge pipe.

[0017] By adopting the above technical solution, the opening and closing of the grout discharge pipe, the grout outlet pipe, and the grout injection pipe are controlled by valves on the grout discharge pipe, the grout outlet pipe, and the grout injection pipe, respectively, so as to open or close the corresponding pipes according to the actual use.

[0018] Optionally, the stirring and scraping assembly includes a second driving component, a stirring rod, and a cleaning plate. The stirring rod is located inside the pulping container. The second driving component is installed on the outer wall of the pulping container and connected to the stirring rod. The stirring rod includes a stirring part and two connecting parts. The two connecting parts are located at both ends of the stirring part. One connecting part is connected to the second driving component, and the other connecting part is rotatably connected to the side wall of the pulping container. The cleaning plate is disposed on the side of the stirring part near the inner wall of the pulping container and abuts against the inner wall of the pulping container.

[0019] By adopting the above technical solution, the materials and water entering the slurry container are fully mixed under the stirring of the stirring rod. At the same time, as the stirring rod rotates under the drive of the second drive component, the cleaning blade scrapes off the concrete mortar adhering to the inner wall of the slurry container, ensuring the cleanliness of the inner wall of the slurry container. This reduces the difficulty of cleaning the inner wall of the slurry container in the future and also reduces the occurrence of concrete mortar being wasted due to the adhesion of concrete mortar to the inner wall of the slurry container.

[0020] Secondly, this application also provides a method for using an integrated grouting device, which includes the following steps:

[0021] S100: Start the grouting process to gradually produce concrete mortar, and simultaneously drive the moving device to the target grouting position;

[0022] S200: The concrete mortar prepared by the grouting component is injected into the pile foundation through the grouting component;

[0023] S300: Restart the mobile device to move to the next target location and repeat step S200.

[0024] In summary, this application includes at least the following beneficial technical effects:

[0025] 1. By setting the mobile device, slurry preparation component and grouting component together on the mobile device, concrete mortar can be made simultaneously during transportation. Compared with the method of rebuilding a fixed mixing plant and restarting it, this saves the time of transportation and restarting the equipment during the entire construction process and improves the grouting efficiency.

[0026] 2. The material crushing component can crush the lumps in the cement and sand mixture in the storage container when it enters the slurry container, so that it can be quickly mixed with water when it enters the slurry container, thereby improving the slurry making efficiency and thus improving the subsequent grouting efficiency.

[0027] 3. By setting filter holes on the connecting part, fine particles in the material can be directly gathered at the discharge port through the filter holes without going through the material channel, thereby increasing the gathering speed of the material at the discharge port.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] Example 1:

[0035] This application discloses an integrated grouting device, referring to... Figure 1-2The system includes a mobile device 1, a pulping assembly 2, and a grouting assembly 3. The mobile device 1 in this application is a vehicle. The pulping assembly 2 includes a water storage container 4, a material storage container 5, and a pulping container 6. The water storage container 4 is used to store clean water and is installed on the mobile device 1 and communicates with the pulping container 6 installed on the mobile device 1. The material storage container 5 is surrounded by a frame installed on the mobile device 1. The pulping container 6 is located below the material storage container 5 and has an outlet 7 below it. The outlet 7 is equipped with a metering valve and communicates with the pulping container 6. The pulping assembly is located at the end of the pulping container 6 away from the water storage container 4. A pulping pipe 21 is provided on the pulping container 6 to connect the pulping container 6 and the pulping assembly. A pump body is also provided on the pulping pipe 21 to extract the prepared pulp from the pulping container 6 and deliver it to the grouting assembly 3 through the pulping pipe 21.

[0036] The grouting assembly 3 includes a three-way connector 22, a grouting pipe 23, and a grout discharge pipe 24. The grout outlet pipe 21 is connected to one port of the three-way connector 22, while the grouting pipe 23 and the grout discharge pipe 24 are connected to the other two ports of the three-way connector 22, respectively. A valve 25 is provided on each of the grout outlet pipe 21, the grouting pipe 23, and the grout discharge pipe 24. When grouting is required, the valves 25 at the grouting pipe 23 and the grout outlet pipe 21 are opened, allowing the prepared concrete mortar in the grouting container 6 to flow through the grout outlet pipe 21 to the grouting pipe 23 for grouting. At this time, the valve 25 at the grout discharge pipe 24 is closed. After grouting is completed, the valve 25 at the grouting pipe 23 can be closed, while the valve 25 at the grout discharge pipe 24 can be opened, allowing excess concrete mortar to be discharged through the grout discharge pipe 24 or collected for reuse.

[0037] Reference Figure 2 and Figure 3The storage container 5 has a cylindrical upper end and an inverted conical lower end. A material crushing assembly 8 is installed at the upper end of the storage container 5. The material crushing assembly 8 includes a lifting component 10, a mounting plate 11, a drive component 12, a rotating rod 13, and a crushing disc 14. The lifting component 10 can be a hydraulic jack, and the drive component 12 is a drive motor. There are two lifting components 10, which are symmetrically distributed about the axis of the storage container 5. The mounting plate 11 is installed on the movable ends of the two lifting components 10. The drive component 12 is installed on the mounting plate 11, and the output shaft of the drive component 12 is connected to the rotating rod 13. The end of the rotating rod 13 away from the drive component 12 is located at the discharge end of the storage container. The interior of the device is fixedly connected to the crushing disc 14. The lower surface of the crushing disc 14 and the inner wall of the lower end of the storage container 5 form a material channel 15 for material entry. The material channel 15 gradually decreases in size from away from the rotating rod 13 to near the rotating rod 13. This allows the agglomerated part of the material to be crushed by the component as the crushing disc 14 rotates after entering the material channel 15 when the material is put into the storage container 5, and then dispersed into finer particles that enter the pulping container 6. At the same time, the size of the material channel 15 can be adjusted by adjusting the lifting part 10 to make the material channel 15 suitable for agglomerated materials of different sizes.

[0038] The pulverizing disc 14 includes a connecting part 16 and a pulverizing part 17, wherein the pulverizing part 17 and the connecting part 16 are fixedly connected. The connecting part 16 is used to connect with the rotating rod 13. A filter hole 18 is provided on the connecting part 16, penetrating the connecting part 16 and the pulverizing part 17. The filter hole 18 is located at the end of the pulverizing part 17 and communicates with the material channel 15 formed between the pulverizing part 17 and the bottom inner wall of the storage container 5. In addition, the distance between the outer wall of the connecting part 16 and the inner wall of the storage container gradually decreases from top to bottom. This allows the material to slide under its own gravity when it falls into the outer wall of the connecting part 16. Smaller particles will slide through the filter hole 18 and fall into the material channel 15 during the sliding process, while lumpy materials will continue to slide downward and enter from the end of the material channel 15. Furthermore, as the connecting part 16 rotates, both small particles and large lumpy materials slide on the connecting part 16, reducing the possibility of lumpy materials clogging the filter hole 18.

[0039] Reference Figure 3 and Figure 4Furthermore, multiple radially extending grinding teeth 19 are provided on the outer wall of the crushing section 17 located inside the material channel 15. The multiple grinding teeth 19 are circumferentially distributed on the outer wall of the crushing section 17 around the axis of the rotating rod 13, so as to increase the crushing speed of the crushing section 17 in crushing the lumpy material in the material channel 15 when rotating. If the lumpy material that is difficult to crush due to close rotation is encountered, the crushing section 17 can be squeezed by lowering the height of the lifting member 10 to improve the crushing efficiency of the crushing section 17.

[0040] Reference Figure 2 and Figure 3 To prevent external dust from seeping in through the gap between the transmission rod and the storage container 5, a telescopic cover 20 is installed between the mounting plate 11 and the storage container 5. The telescopic cover 20 is fitted over the outside of the rotating rod 13. One end of the telescopic cover 20 is connected to the mounting plate 11, and the other end is connected to the outer wall of the storage container 5. This ensures that when the lifting component 10 is raised or lowered, it will also lift or lower the telescopic cover 20 together, thus ensuring the cleanliness of the rotating rod 13 and preventing external dust from entering the storage container 5. At the same time, it also prevents the material dust in the storage container 5 from escaping when the crushing disc 14 rotates, thereby maintaining a clean construction environment.

[0041] The pulping container 6 is a horizontally placed cylinder. A stirring and scraping assembly 9 is provided at the end of the pulping container 6 away from the water storage container 4. The stirring and scraping assembly 9 includes a second drive component 26, a stirring rod 27, and a cleaning plate 28. The second drive component 26 is also a drive motor. The second drive component 26 is installed on the outer wall of the pulping container 6 away from the water storage container 4. The stirring rod 27 includes two connecting parts 29 and a stirring part 30. The two connecting parts 29 are located at both ends of the stirring part 30 and are fixedly connected to the stirring part 30. The stirring part 30 is U-shaped. One connecting part 29 is connected to the output shaft of the drive motor, while the other connecting part 29 is rotatably connected to the inner wall of the pulping container 6 near the water storage container 4. When the second drive component 26 is started, the two connecting parts 29 and the stirring part 30 start to rotate around the axis of the pulping container 6, thereby stirring the material and water in the pulping container 6 to improve the mixing efficiency between the material and the water.

[0042] Furthermore, a cleaning plate 28 is provided on the side of the stirring section 30 near the inner wall of the pulping container 6. The cleaning plate 28 is made of silicone and abuts against the inner wall of the pulping container 6, thereby cleaning the inner wall of the pulping container 6 as the stirring rod 27 rotates.

[0043] The implementation principle of this application embodiment is as follows: After the grouting work in the current area is completed, clean water is added to the water storage container 4, and material is added to the material storage container 5. The added material is crushed and ground under the action of the material crushing component 8 and piled up at the discharge port 7. Then, the moving device 1 is started to transfer to the next target area. During the transfer process, the material in the material storage container 5 and the clean water in the water storage container 4 are sent into the slurry container 6 in proportion. At the same time, the stirring and scraping component 9 is started to stir and mix the clean water and material in the slurry container 6. When the target area is reached, the grouting of each pile foundation in the target area can be performed through the slurry discharge component.

[0044] Example 2:

[0045] Embodiment 2 of this application also provides a method for using the integrated grouting equipment in Embodiment 1, including the following steps:

[0046] S100: After the grouting of the previous target area is completed, add clean water to the water storage container 4 and add material to the material storage container 5 before starting the mobile device 1.

[0047] S200: Start the mobile device 1 to move to the next target area. During the movement, start the material in the storage container 5 and the clean water in the water storage container 4 to be sent into the slurry container 6 in proportion. At the same time, start the stirring and scraping component 9 to stir and mix the clean water and material in the slurry container 6 to prepare concrete mortar.

[0048] S300: After reaching the next target area, open the valve 25 on the grout outlet pipe 21 and the grout injection pipe 23, and close the valve 25 on the grout discharge pipe 24 to perform grouting;

[0049] S400: After grouting work in the current area is completed once, close valve 25 on grouting pipe 23 and open valve 25 on grout discharge pipe 24 to recover the concrete mortar remaining in tee connector 22 and grouting pipe 23.

[0050] 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.
