Description

Technical Field

[0001] The invention belongs to the technical field of grouting devices, and in particular relates to a structural gap grouting device for a building engineering project. Background Art

[0002] During the construction of a building project, gaps may appear at some structural joints, which need to be grouted to enhance the overall stability of the building and avoid later damage to the building. During the grouting process, grouting equipment is required to inject concrete slurry into the gaps. For example, a structural gap grouting device for construction engineering is proposed in patent publication number CN115874839A.

[0003] When working, the existing filling device mainly relies on conveying components such as pumps to inject slurry into the gaps. However, due to differences in construction technology, construction quality and concrete materials in different construction projects, when gaps appear in the construction project structure, their widths and depths are often different. The traditional filling device only conveys slurry to the gaps through one filling head, which makes the conveying efficiency relatively slow. In addition, when the gaps are filled, the slurry will overflow from the gaps. At this time, the operator will manually control the grouting device to stop working only after seeing the slurry overflowing, which leads to waste of slurry.

After the grouting device is used to fill the gap with slurry, the grouting device can be controlled to stop working in time, thereby avoiding the problem that the operator manually closes the grouting device, which will cause the slurry to overflow from the gap and cause slurry waste.

[0026] The operating principle of the present invention is now described as follows: before grouting the gap of the construction engineering structure, the gap is first pre-processed by grooving using external grinding and cutting equipment according to needs to facilitate the grouting operation, and then the vehicle body 1 is moved to the gap of the construction engineering structure, so that the vehicle body 1 is aligned with one end of the gap, and then the vehicle body 1 is moved. At the same time, the operator sends a control signal to the PLC controller 4 through the control button 3. After receiving the control signal, the PLC controller 4 first controls the high-pressure water pump 302 and the first magnetic control valve 32 to work simultaneously, and the high-pressure water pump 302 pumps the water in the water tank 301. The water is transported to the water spray head 31 for spraying, and the water spray head 31 sprays high-speed water flow to the gap to clean out the impurities remaining in the gap. At the same time, the PLC controller 4 controls the high-pressure air pump 35 to work, and the high-pressure air pump 35 blows high-speed air flow to the gap to clean out the water remaining in the gap. When the operator moves the vehicle body 1 to an appropriate distance (the operator can see the cleaned gap from the rear of the vehicle body 1), the high-pressure water pump 302 and the high-pressure air pump 35 are immediately stopped by the control button 3 and the PLC controller 4. Then the operator moves the vehicle body 1 while observing to align the rear end of the injection box 8 with the rear end of the gap. Then the operator transmits a start signal to the PLC controller 4 through the control button 3. After receiving the electric signal, the PLC controller 4 first controls the two vertical electric push rods 7 to work. The two vertical electric push rods 7 drive the injection box 8 to move downward together, so that the injection box 8 contacts the ground. A part of the injection tube 10 stops moving after contacting the ground, while the injection box 8 still moves downward under the action of the vertical electric push rods 7, so that the injection tube 10 moves upward relatively in the injection box 8. When the baffle plate 15 on the lower surface of the injection box 8 contacts the ground, the injection tube 10 in contact with the ground drives the sealing plate 14 and other components to move to the storage port 16 for storage, and the upper end of the part of the injection tube 10 drives the baffle cover 18 to move upward and contact the baffle block 20, and the baffle block 20 is used to block the feed port 19 on the surface of the baffle cover 18. The injection pipe 10 located just above the gap will extend into the gap. When the two vertical electric push rods 7 stop working, the PLC controller 4 will control the material pump 6 to work. The material pump 6 transports the slurry in the filling barrel 5 to the injection box 8, and transports the slurry into the gap through the injection pipe 10 extending into the gap. When the width and length of the gap are relatively small, only a small amount of the injection pipe 10 will extend into the gap. At this time, the injection speed of the slurry is less than the feeding speed of the material pump 6, and the hydraulic pressure in the injection box 8 will quickly When the hydraulic pressure sensor 44 detects that the hydraulic pressure in the injection box 8 reaches the set threshold, the hydraulic pressure sensor 44 will control the power of the material pump 6 to continue to decrease through the PLC controller 4 until the slurry speed delivered by the material pump 6 to the injection box 8 is equivalent to the discharge speed of the injection pipe 10. The material pump 6 will continue to work at a lower power, avoiding the problem that the feeding speed of a single injection pipe 10 is too fast and collides with the gap, causing a large amount of air to be mixed into the slurry, causing more bubbles to be generated inside the slurry, and affecting the slurry quality. When the amount of slurry in the gap increases, the liquid level of the slurry will gradually rise. In the process of moving upward, the liquid level of the slurry will push the floating ring 22, so that the floating ring 22 drives the vertical rod 212 to move upward, and the vertical rod 212 will press upward to the pressure sensor 24. After the pressure sensor 24 is squeezed, an electrical signal will be transmitted to the PLC controller 4. After receiving the electrical signal, the PLC controller 4 will control the material pump 6 to stop working, and at the same time, the PLC controller 4 will control the buzzer 29 to work, reminding the operator that the grouting operation has been completed and the grouting operation can be carried out at the next location; When all the grouting operations are completed, the operator can send an electrical signal to the PLC controller 4 through the control button 3. After receiving the electrical signal, the PLC controller 4 will control the high-pressure water pump 302 and the second magnetic control valve 34 to work, and control the control valve 9 to close. The high-pressure water pump 302 transports the water in the water tank 301 to the injection box 8 through the cleaning pipe 33, and the high-pressure water flow will be discharged through the injection pipe 10. The high-pressure water flow can wash away the slurry attached to the inner wall of the injection pipe 10. When there is solidified slurry on the inner wall of the injection pipe 10 and the high-pressure water flow cannot wash it away, when the subsequent material pump 6 transports the slurry to the injection box 8 and discharges it through the injection pipe 10, the injection pipe 10 will The sealing plate 14 will be subjected to greater pressure due to poor fluidity, and the distance that the injection tube 10 drives the sealing plate 14 to move downward will be much greater than that of other normal injection tubes 10. The sealing plate 14 will drive the lifting plate 252 to move downward a longer distance through the pull rope 26, so that the lifting plate 252 presses the squeeze switch 27 at that location, and the squeeze switch 27 will control the buzzer 29 and the prompt lamp bead 28 at that location through the PLC controller 4. The buzzer 29 reminds the operator with different tones that the injection tube 10 is blocked (when the gap is filled with material, the buzzer 29 reminds the operator with a beeping sound, and when the injection tube 10 is blocked, the buzzer 29 reminds the operator with a clicking sound); After the operator finishes the work of the grouting device and cleans the injection pipe 10, the operator lifts the grouting device to a certain height through the external lifting device. The operator can find the blocked injection pipe 10 under the grouting device through the prompt light bead 28. The operator removes the injection pipe 10 from the device by rotating the injection pipe 10, and then inserts it into the mounting ring 40, and fixes the mounting ring 40 with the clamp positioning bolt 41. Then the operator controls the small electric push rod 372 through the control button 3 and the PLC controller 4 to drive the dredging rod 38 to reciprocate up and down once. The dredging rod 38 drives the scraper plate 39 to move in the injection pipe 10, and the scraper plate 39 is used to clean the slurry adhering to the injection pipe 10. Then, the injection pipe 10 is installed to the original position, and the grouting device is placed on the ground through the external lifting device.
