All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Reference Figs. 1-3 A precast shear wall grouting material conveying device includes a storage tank 3 and a screw pump 4. The storage tank 3 is used to store grouting material. The storage tank 3 is equipped with a sealing cover 1 to seal the storage tank 3 and prevent the grouting material from losing moisture and causing surface solidification. The sealing cover 1 is equipped with a stirring blade 21. The stirring blade 21 can be opened with holes to facilitate the flow of grouting material. The bottom of the storage tank 3 is funnel-shaped. The diameter of the stirring blade 21 gradually decreases from top to bottom. The outer edge of the stirring blade 21 is adapted to the inner wall of the storage tank 3. The sealing cover 1 is equipped with a control device 2 corresponding to the stirring blade 21. The edge of the stirring blade 21 is attached to the inner wall of the storage tank 3. The control device 2 adopts a motor or a manual crank to control the rotation of the stirring blade 21 to stir the grouting material upward or downward, and at the same time scrapes the inner wall of the storage tank 3 to prevent the grouting material from adhering to the inner wall of the storage tank 3.

[0022] The screw pump 4 is connected to the bottom outlet of the storage tank 3. The screw pump 4 steadily pumps the grouting material in the storage tank 3 out. A drive motor 8 is provided on one side of the screw pump 4. A controller is provided on the drive motor 8 to control the working parameters of the drive motor 8. The outlet of the screw pump 4 is provided with a quick-release pipe 5. The screw pump 4 includes a conveying screw 42 and a pump body 43. A feed pipe 41 is provided on the upper side of the pump body 43. The lower end of the stirring blade 21 extends into the feed pipe 41. The grouting material is pushed downward by the rotation of the stirring blade 21. The output shaft of the drive motor 8 is connected to the conveying screw 42. The pump body 43 and the quick-release pipe 5 are detachably connected. The conveying screw 42 extends into the quick-release pipe 5. When blockage occurs or the grouting material solidifies, the quick-release pipe 5 can be quickly opened to clean the conveying screw 42.

[0023] The quick-release pipe 5 is connected to a flow regulating valve 6, which is used to regulate the flow rate of the grouting material. A pressure sensor 61 is provided on one side of the outlet of the flow regulating valve 6. The outlet of the flow regulating valve 6 is connected to a quick-release pipe interface 7. The quick-release pipe interface 7 is connected to a grouting gun 70 through the grouting pipe. The grouting gun 70 and the grouting pipe are quick-released. The nozzle of the grouting gun 70 is designed to be replaceable. Different nozzle specifications can be selected according to different grouting needs. The grouting gun 70 is also equipped with a trigger to control the spraying of the grouting material.

[0024] Pressure sensor 61 is installed between flow regulating valve 6 and grouting gun 70. Flow regulating valve 6 is electrically controlled. Flow regulating valve 6, pressure sensor 61 and controller are electrically connected. Pressure sensor 61 is used to monitor the pressure of grout in the pipeline in real time and transmit the pressure signal to the controller. The controller automatically adjusts the speed of drive motor 8 and the opening of flow regulating valve 6 according to the pressure signal fed back by pressure sensor 61 to ensure the stability of grout pressure and flow.

[0025] The storage tank 3 is connected to a return pipe 9. One end of the return pipe 9 is connected to the grout outlet 90 of the precast shear wall 11, and the other end of the return pipe 9 is connected to the lower part of the storage tank 3 to ensure that the recovered grout is used as soon as possible and to avoid mixing and affecting the overall quality of the grout. A one-way valve 91 is installed on the return pipe 9. The one-way valve 91 is set vertically and installed at the end of the return pipe 9 near the storage tank 3 to prevent the grout in the storage tank 3 from flowing back. A filter assembly is installed at the inlet of the return pipe 9. The filter assembly is set inside the return pipe 9 to filter impurities in the returned grout and ensure the quality of the recovered grout.

[0026] In this embodiment, a grouting sleeve 10 is provided inside the precast shear wall 11, and a grouting hole 71 and a grout outlet 90 are provided on one side of the precast shear wall 11.

[0027] 1. When using this device, first pour the grouting material into the storage tank 3;

[0028] 2. Rotate the stirring blades 21 to push the grouting material downwards, start the drive motor 8, and the grouting material is sucked into the screw pump 4 from the discharge port at the bottom of the storage tank 3 and transported to the flow regulating valve 6 through the pipeline;

[0029] 3. According to construction requirements, the flow rate of grouting material is controlled by adjusting the opening of the flow regulating valve 6 via electric control;

[0030] 4. Pressure sensor 61 monitors the pressure of the grouting material in the pipeline in real time and transmits the pressure signal to the controller; the controller automatically adjusts the speed of drive motor 8 according to the pressure signal to maintain the pressure of the grouting material.

[0031] 5. The operator holds the grouting gun 70, aims the gun head at the grouting hole 71 of the precast shear wall 11, and pulls the trigger to spray the grouting material into the grouting hole 71; when it is necessary to change the grouting hole 71 of different specifications, the corresponding gun head can be replaced.

[0032] 6. During the grouting process, if excess grout overflows from the outlet 90, the overflowing grout enters the storage tank 3 through the return pipe 9. During the return process, the one-way valve 91 ensures that the grout can only flow into the storage tank 3 in one direction. The filter assembly filters the returned grout to remove any impurities that may be mixed in.

[0033] 7. After construction is completed, turn off the drive motor 8, clean the pipes and storage tank 3 for future use; at the same time, the filter components can be cleaned or replaced to ensure the normal operation of the slurry outlet 90 return device for the next use.
