[0001] This invention relates to the field of construction engineering technology, specifically to a multifunctional portable grouting device for small-area reinforcement and seepage prevention. Background Technology

[0002] With China's investment in infrastructure construction, civil engineering construction and maintenance have developed significantly. However, the construction process of projects such as highways, tunnels, bridges, mines, and dams may encounter sudden water inrushes, and cracks may develop in the structural components during their service life, all of which can cause substantial damage to infrastructure.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0024] To address the technical problem that existing grouting devices are not suitable for grouting operations in small areas, this invention provides a multifunctional portable grouting device that can be used for construction operations in small areas, greatly improving the applicability of the grouting device.

[0025] The multifunctional portable grouting device provided by the present invention includes a grouting unit, a pressure application unit, a reaction unit, a stirring unit, and a grouting nozzle.

[0026] Further, see Figures 1-2 The grouting unit is connected to the reaction unit and includes several grouting pipes. The number of grouting pipes is not limited in this scheme and is determined according to the composition of the mixed grout.

[0027] This scheme uses two grouting pipes, namely the first grouting pipe 110 and the second grouting pipe 120.

[0028] The first grouting pipe 110 is used to store liquid A in the mixed grout, and the second grouting pipe 120 is used to store liquid B in the mixed grout.

[0029] The first grouting pipe 110 and the second grouting pipe 120 are set separately. At the same time, the first grouting pipe 110 and the second grouting pipe 120 are equipped with independent valves, namely the first valve 111 and the second valve 121. The first grouting pipe 110 and the second grouting pipe 120 can be opened and closed through the first valve 111 and the second valve 121.

[0030] Secondly, the first valve 111 and the second valve 121 can be opened independently or simultaneously according to the grouting requirements to achieve the effect of single or mixed grouting materials.

[0031] In addition, the first valve 111 and the second valve 121 are adjustable and have flow metering function, which can calculate the volume of grout injected into the reaction chamber in real time.

[0032] One end of the first grouting pipe 110 and the second grouting pipe 120 passes through the first reinforcing plate 610 and is connected to the second reinforcing plate 620. By setting the first reinforcing plate 610 and the second reinforcing plate 620, the impact force of the first grouting pipe 110 and the second grouting pipe 120 during grouting and the weight of the pipe itself can be dispersed, thereby enhancing the reliability of the first grouting pipe 110 and the second grouting pipe 120 during operation.

[0033] The first grouting pipe 110 and the second grouting pipe 120 pass through the first reinforcing plate 610 and the second reinforcing plate 620 and are connected to the reaction unit. Liquid A and liquid B in the first grouting pipe 110 and the second grouting pipe 120 are injected into the reaction unit for mixing and reaction.

[0034] A first one-way valve 112 and a second one-way valve 122 are respectively provided at the ports where the first grouting pipe 110 and the second grouting pipe 120 are connected to the reaction unit. The first one-way valve 112 and the second one-way valve 122 can open or close the channel between the first grouting pipe 110, the second grouting pipe 120 and the reaction unit.

[0035] Meanwhile, the first one-way valve 112 and the second one-way valve 122 can only flow in one direction, which can prevent the grout injected into the reaction unit from flowing back into the grouting stock in the first grouting pipe 110 and the second grouting pipe 120.

[0036] Furthermore, the pressurizing unit includes a high-pressure pipe 210, a pressure valve 211, and a third check valve 212.

[0037] One end of the high-pressure pipe 210 is connected to a high-pressure pump, which can provide high pressure to the high-pressure pipe 210.

[0038] Pressure valve 211 is installed on high pressure pipe 210, and pressure valve 211 can be used to open and close high pressure pipe 210.

[0039] Secondly, the pressure valve 211 has an adjustable function and the maximum pressure can ensure that the grout can still be sprayed out when the grout reaction chamber is full.

[0040] The other end of the high-pressure pipe 210, like the first grouting pipe 110 and the second grouting pipe 120, passes through the first reinforcing plate 610 and the second reinforcing plate 620 in sequence and is connected to the reaction unit to transport the high pressure in the high-pressure pipe 210 to the reaction unit.

[0041] A third check valve 212 is provided at the port where the high-pressure pipe 210 is connected to the reaction unit. The channel between the high-pressure pipe 210 and the reaction unit can be opened or closed through the third check valve 212.

[0042] The third one-way valve 212 allows only one-way flow, preventing the grouting fluid in the grouting fluid reaction chamber from flowing back into the high-pressure pipeline 210.

[0043] The arrangement of the first grouting pipe 110, the second grouting pipe 120, and the high-pressure pipe 210 on the first reinforcing plate 610 and the second reinforcing plate 620 is not limited in this scheme. A triangular distribution is preferred because the triangular distribution results in uniform stress and also has a better visual effect. The specific distribution method can be determined according to the actual situation.

[0044] The reaction unit is a reaction chamber 310. The interior of the reaction chamber 310 is a hollow cavity. One end of the chamber is connected to the first reinforcing plate 610, and the other end is connected to the grouting nozzle 410.

[0045] The outlets of the second reinforcing plate 610, the first grouting pipe 110, the second grouting pipe 120, and the high-pressure pipe 210 are located inside the reaction chamber 310. Liquid A and liquid B in the first grouting pipe 110 and the second grouting pipe 120 can be transported to the reaction chamber 310 for mixing. After mixing, the mixed slurry in the reaction chamber 310 can be sprayed out through the grouting nozzle 410 through the high pressure in the high-pressure pipe 210.

[0046] In this scheme, the grouting nozzle 410 is preferably a conical grouting nozzle. The conical grouting nozzle has a large spray radius and a smooth flow channel, which can reduce the occurrence of blockage.

[0047] In addition, to ensure the full reaction of the mixed slurry in the reaction chamber 310, this scheme is also equipped with a stirring unit, which can stir the mixed slurry in the reaction chamber 310 and ensure full reaction.

[0048] The stirring unit includes a drive assembly 510 and a stirring assembly 520, with the drive assembly 510 driving and connecting the stirring assembly 520.

[0049] The drive assembly 510 is used to drive the stirring assembly 520 to rotate. The drive assembly 510 is disposed between the first reinforcing plate 610 and the second reinforcing plate 620. One end of the drive assembly 510 is equipped with an external charging cable 511, which can realize wired and wireless independent operation. The end of the drive assembly 510 is located on the second reinforcing plate 620 and is connected to the stirring assembly 520, which can drive the stirring assembly 520 to rotate.

[0050] The structure of the drive component 510 is not limited in this scheme. The preferred option is a high-speed motor. The high-speed motor can ensure that the grouting liquid reaction chamber can still be stirred at high speed when it is full, so that the grouting mixture can react fully under the action of the stirring component 520.

[0051] One end of the stirring assembly 520 passes through the second reinforcing plate 620 and is connected to the drive assembly 510, while the other end is located inside the reaction chamber 310, and is used to stir the slurry inside the reaction chamber 310.

[0052] In this design, the stirring component 520 preferably adopts a spiral stirring rod. The spiral stirring rod has low energy consumption, high stirring efficiency and strength, and meets the requirements of fast mixing speed, uniformity and thoroughness. It is suitable for emulsions, suspensions and the like.

[0053] Finally, all parts of this multifunctional portable grouting device are preferably made of waterproof, rustproof, and corrosion-resistant materials, and the exterior is coated with a special material to ensure the lifespan of the grouting device.

[0054] The following example illustrates its working process in a specific application. However, it should be noted that the following content is only a specific application example of this solution and does not constitute a limitation on this solution.

[0055] First, simultaneously open the first valve 111, the second valve 121, the first check valve 112, and the second check valve 122 to inject liquid A and liquid B from the first grouting pipe 110 and the second grouting pipe 120 into the reaction chamber 310.

[0056] Then, turn on the high-speed motor 510, which drives the stirring rod 520 to rotate at high speed, so as to stir and fully react the A liquid and B liquid in the reaction chamber 310.

[0057] Finally, the pressure valve 211 and the third check valve 212 are opened, and the high pressure in the high pressure pipe 210 sprays the grout in the reaction chamber 310 through the grouting nozzle 410 to the location that needs to be reinforced or seepage-proofed.

[0058] The multifunctional portable grouting device constructed using the above scheme can be used for large-scale grouting operations or for construction in small areas, greatly improving the applicability of the grouting device.

[0059] Secondly, its structure is simple, easy to carry, convenient to operate, improves the overall operation effect, and avoids secondary large-scale grouting; at the same time, this grouting device is portable and easy to operate by a single person. It can complete the mixing, stirring and grouting process of grouting materials with a variety of grouts in one integrated process, avoiding the secondary transfer of grouting materials in grouting projects.
