Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0021] like Figure 1 , 2 As shown, an integrated grouting equipment for automated grout preparation includes a material storage module 100, a cement automatic control batching and mixing station module 200, and a high-pressure jet grouting background control module 300.

[0022] The material storage module 100 includes a cement silo 101 and an auger conveyor channel 102, the auger conveyor channel 102 being connected to the cement silo 101;

[0023] The cement automatic control batching and mixing plant module 200 includes a first module frame 201 and a water storage tank 202, an admixture tank 203, a premixing mixing tank 204, a weighing system 205, a pneumatic valve switch 206, a secondary mixing tank 207, and an automated intelligent control system 208, all mounted on the first module frame 201. The auger conveyor channel 102, the water storage tank 202, and the admixture tank 203 are respectively connected to the premixing mixing tank 204. The weighing system 205 is mounted on the premixing mixing tank 204. The secondary mixing tank 207 is connected to the premixing mixing tank 204. The pneumatic valve switch 206 is located between the secondary mixing tank 207 and the premixing mixing tank 204. The automated intelligent control system 208 is electrically connected to the auger conveyor channel 102, the water storage tank 202, the admixture tank 203, the weighing system 205, and the pneumatic valve switch 206, respectively.

[0024] The high-pressure jet grouting background control module 300 includes a second module frame 301 and an automatic mixing grout storage tank 302, a high-pressure grouting pump 303, and a high-pressure grout output pipeline 304, which are installed on the second module frame 301. The secondary mixing tank 207, the automatic mixing grout storage tank 302, the high-pressure grouting pump 303, and the high-pressure grout output pipeline 304 are connected in sequence.

[0025] The above structure forms three independent modules. The equipment on each module can be pre-connected. Then, the modules are transported to the construction site and connected to each other, thereby realizing the rapid assembly of the grouting equipment and effectively improving construction efficiency.

[0026] The auger conveying channel 102 includes a hydraulic jack 103, a movable partition 104, a horizontal auger 105, and a vertical auger 106. The hydraulic jack 103 is connected to the movable partition 104, which is mounted on the horizontal auger 105. The horizontal auger 105 is connected to the vertical auger 106, which is connected to the premixing mixing tank 204. The automated intelligent control system 208 is electrically connected to the hydraulic jack 103.

[0027] The cement automatic control batching and mixing plant module 200 also includes a rear-embedded material storage bin 209, which is set on the first module frame 201 and is used to place accessories, so that the cement automatic control batching and mixing plant module 200 can quickly replace accessories and repair them in case of failure.

[0028] Water pumps (not shown in the figure) are installed on the water storage tank 202 and the admixture tank 203 respectively. The automated intelligent control system 208 is electrically connected to the water pumps on the water storage tank 202 and the admixture tank 203 respectively.

[0029] The cement automatic batching and mixing plant module 200 also includes a screen hopper 210, which is located between the secondary mixing tank 207 and the pre-mixing tank 204.

[0033] The material storage module 100 also includes a dust collector 107, which is installed on the cement silo 101 to prevent dust from being generated when adding bulk cement.

[0034] When the above equipment operates, the weight ratio parameters of the mixing materials are first set on the automated intelligent control system 208. Then, the automated intelligent control system 208 controls the water pumps on the hydraulic jacks 103, water storage tank 202, and admixture tank 203 in the auger conveying channel 102 to sequentially transport the materials to the premixing mixing tank 204. The weighing system 205 on the premixing mixing tank 204 weighs each material one by one. After the system requirements are met, the feeding stops. The premixing mixing tank 204 premixes the slurry. After the premixing is completed, the automated intelligent control system 208 controls the pneumatic valve switch 206 to open. The premixed cement slurry is then transported to the secondary mixing tank 207 for mixing. During the cement slurry transportation process, larger particles in the cement slurry are filtered through the sieve 210. After being mixed in the secondary mixing tank 207, the cement slurry is transported to the automatic mixing storage tank 302, and then pressurized by the high-pressure grouting pump 303 and transported to the high-pressure slurry output pipeline 304 to realize the grouting operation.
