By precisely injecting grouting material into the cracks, it achieves structural reinforcement and waterproofing. The device mainly consists of a grouting pump, grouting pipe, mixing system, and control system. The grouting pump provides stable pressure and pushes cement-based, epoxy resin, and other grouts along the grouting pipe to the crack.

[0003] Existing concrete crack grouting devices often result in irregular crack shapes, and the flexible grouting pipe may bend and deform when inserted into the crack for grouting. This can affect the insertion depth of the grouting pipe end, leading to grout accumulation and thus affecting the quality of grouting repair. Utility Model Content

[0004] To overcome the problem that existing concrete crack grouting devices often result in irregular cracks, and the flexible grouting pipe may bend and deform when inserted into the crack, thus affecting the insertion depth of the grouting pipe end and causing grout accumulation, thereby affecting the grouting repair quality.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Among the currently discovered feasible technologies, the following are described:

[0023] Cracks in concrete are a common problem in building construction. Their causes are complex and varied, including temperature changes, shrinkage, uneven foundation settlement, load effects, and material quality issues. Cracks not only affect the aesthetics of buildings but also reduce the structural load-bearing capacity, leading to problems such as leakage and steel corrosion. In severe cases, they can even threaten building safety. Grouting repair technology is one of the effective means of treating concrete cracks, and precise grouting positioning is a key prerequisite for ensuring the effectiveness of grouting repair. By accurately injecting grouting material into the cracks, it is possible to fill the cracks, enhance the overall integrity of the structure, restore structural function and waterproof performance.

[0024] Physical contact positioning mainly relies on the direct contact between mechanical devices and the concrete surface or cracks to determine the grouting location. For example, using components such as telescopic rods or positioning rods with scales, the location and direction of the cracks are manually measured and marked, and then the grouting pipe is fixed in the corresponding position. This method is simple in principle and suitable for situations where the crack location is relatively obvious, the environmental conditions are good, and the accuracy requirements are not too high. However, it has the disadvantages of low efficiency and large human error.

[0025] Optical positioning technology utilizes the propagation characteristics of light to locate cracks. Laser positioning is a common optical positioning method. It emits a laser beam, which is projected onto the concrete surface to form a clear light spot or band. Construction workers adjust the position of the grouting equipment according to the relative position of the light spot and the crack, so that the grouting port is aligned with the crack.

[0026] It consists of a laser emitter, a laser modulator, and a laser receiver. The laser emitter emits a stable laser beam, the laser modulator can adjust the intensity, width, and direction of the laser beam, and the laser receiver is used to receive the reflected laser signal to determine the accuracy of the positioning.

[0027] Before grouting, a comprehensive inspection and assessment of concrete cracks is required. Tools such as visual inspection, crack width gauges, and ultrasonic detectors are used to determine the location, length, width, depth, direction, and development trend of the cracks.

[0028] Based on the distribution of cracks and repair requirements, determine the grouting positioning points. For cracks with small width and uniform distribution, positioning points can be evenly arranged at a certain interval; for cracks with large width and severe local conditions, the positioning points should be densified at critical parts of the crack (such as crack ends and bifurcations). At the same time, considering the characteristics of the grouting material and the grouting process, and taking into account the diffusion radius of the grout, the spacing of the positioning points should be reasonably determined to ensure that the cracks can be fully filled.

[0029] Transport the grouting positioning device to the construction site and install it according to the instructions. During installation, ensure that all components of the positioning system, drive system, and control system are securely connected and accurately installed. After installation, perform equipment debugging, checking whether the laser positioning module's beam is accurate, whether the machine vision positioning module's image acquisition and processing are normal, whether the drive system operates smoothly, and whether the control system's commands are accurately executed. Grouting positioning operations can only be carried out after the debugging is qualified.

[0030] Once the grouting equipment is positioned, the grouting pipe and grouting pump are connected, and the grouting operation begins. During the grouting process, parameters such as grouting pressure, grouting flow rate, and grouting volume are monitored in real time using pressure sensors, flow sensors, and other sensors.

[0031] Please refer to Figures 1-5 A concrete crack grouting positioning device includes a mounting base 1 and a grouting pipe 2. A connector 8 is fixedly mounted on the side wall of the mounting base 1. The grouting pipe 2 is sleeved on the outer surface of the connector 8. A first connecting rod 3 is fixedly mounted on the side wall of the mounting base 1 near the grouting pipe 2. Several sets of limiting components 4 are provided at the end of the first connecting rod 3. Each limiting component 4 includes a second connecting rod 401 rotatably connected to the end of the first connecting rod 3. A first locking block 402 is fixedly mounted at one end of each second connecting rod 401. A second limiting seat 11 is fixedly mounted at the end of the first connecting rod 3. The second limiting seat 11 and the first locking block 402 are rotatably connected together. A first limiting seat 404 is rotatably connected to the other end of each second connecting rod 401. First clamps 403 are fixed on the wall. First connecting rods 3 and second connecting rods 401 are linearly distributed. Third clamps 10 are fixed on the side wall of first connecting rod 3. Third clamps 10 and first clamps 403 are both sleeved on the outer surface of grouting pipe 2, which improves the stability of grouting pipe 2 installation. The end of second connecting rod 401 away from mounting seat 1 is rotatably connected to third connecting rod 5. Second clamps 12 are fixed on the end of third connecting rod 5. Second clamps 12 are rotatably connected to the middle of first limiting seat 404. Several second clamps 6 are fixed on the side wall of third connecting rod 5. The middle of second clamps 6 is clamped to discharge pipe 7. The other end of grouting pipe 2 is sleeved on the outer surface of discharge pipe 7. Discharge pipe 7 is connected to connector 8.

[0032] A connecting seat 9 is inserted into the end of the mounting base 1 away from the plug 8. The connecting seat 9 is threaded to the output end of the grouting pump. The first locking block 402 is rotatably connected in the middle of the first limiting seat 404. The external dimensions of the first locking block 402 are adapted to the internal dimensions of the first limiting seat 404, which improves the convenience of rotating the second connecting rod 401.

[0033] The third link 5, the second clamp 6, and the discharge pipe 7 are fixedly connected to form an integrated structure. The bottom end of the third link 5 is fixed with a thermal imager probe 13. The thermal imager probe 13 can receive the infrared energy radiated by the target object and focus it onto the detector chip through the optical system. The thermal imager probe 13 can be connected to an external display to show the distribution inside the crack for the operator to observe, which improves the convenience of plug-in detection.

[0034] When using this concrete crack grouting positioning device, the operator first moves the device to the designated position, then connects the external power supply, and then threads the connecting seat 9 to the output end of the grouting pump. The grouting pump is a device used to transport grouting materials. It drives a piston or impeller to press cement slurry, chemical slurry, etc. into the strata, cracks, or holes to play a role in seepage prevention, leak sealing, and reinforcement. The grouting pump is existing technology and will not be described in detail here. The two ends of the grouting pipe 2 are sequentially fitted onto the ends of the plug joint 8 and the connecting seat 9 to achieve connection. The grouting pipe 2 is then sequentially inserted between the third clamp 10 and the first clamp 403. The second connecting rod 401 and the first clamp 403 provide support and limit, thereby improving the overall stability of the grouting pipe 2 inserted into the building crack. The first clamp 402 and the first limiting seat 404 cooperate to improve the convenience of adjusting the angle of the second connecting rod 401 and the grouting pipe 2, thereby improving the stability of the grouting pipe 2 insertion and positioning, avoiding bending and folding of the grouting pipe 2, and thus improving the quality of grouting.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
