Technical Field

[0001] This utility model relates to the field of building engineering and underground engineering construction technology, and more specifically to a distributed multi-point synchronous grouting device. Background Technology

[0002] Grouting is a commonly used technique in engineering projects such as building foundation reinforcement, tunnel construction, and mine support. Traditional grouting devices typically employ single-point grouting, resulting in low grouting efficiency and difficulty in achieving simultaneous grouting at multiple grouting holes, leading to long construction cycles. Furthermore, traditional devices lack precision in grouting pressure control and grout flow regulation, easily causing problems such as grout leakage and uneven grouting effects. In addition, the connections between components in existing devices are not convenient, and the filtration and mixing effects are poor, affecting grouting quality and efficiency. Therefore, there is an urgent need for a distributed multi-point synchronous grouting device that can achieve multi-hole synchronous continuous grouting, precise pressure control, and convenient operation.

[0037] 1. Equipment Installation: Place the cement slurry mixing tank 1 and water glass storage tank 2 in suitable locations, ensuring stability.

[0038] 2. Usage Method: Add cement and water to the cement slurry mixing tank 1, start the spiral blade agitator, and mix evenly to form cement slurry; store water glass in the water glass storage tank 2, monitor the level in real time using a liquid level sensor, and maintain the temperature inside the tank within a suitable range using a temperature controller. Determine the grouting hole positions according to construction requirements, and insert the grouting pipe 8 into the corresponding grouting hole. Set preset pressure thresholds and other parameters through the central controller, and open valves 3 on the first feed pipe 9 and the second feed pipe 10 to control the delivery of cement slurry and water glass. Start the multi-hole diversion grouting pump 4, driving the cement slurry and water glass through the diversion grouting hose 5 and the grouting pipe 8 to deliver them to each grouting hole position, achieving multi-hole synchronous continuous grouting. During the grouting process, the pressure gauge monitors the grouting pressure in real time. When the pressure exceeds or falls below the preset threshold, the regulating valve automatically adjusts the slurry flow rate, and the central controller dynamically adjusts the pumping parameters based on the pressure data of each grouting hole position to ensure a stable grouting process. After grouting is completed, close the multi-hole diversion grouting pump 4 and all valves 3, disassemble the grouting pipe 8 and the diversion grouting hose 5, and clean and maintain them.

Check the sealing performance of the quick-connect couplings; replace them immediately if damaged to prevent grout leakage. Keep the cement grout mixing tank 1 and the water glass storage tank 2 clean and perform regular maintenance. When setting the parameters of the central controller, it is necessary to set them reasonably according to the specific construction conditions and requirements to ensure the grouting effect.

[0040] In summary, the distributed multi-point synchronous grouting device of this utility model achieves multi-hole synchronous continuous grouting through reasonable structural design and intelligent control, which improves grouting efficiency and quality.
