Automatic grout preparation system and method

Abstract

The invention discloses an automatic grout preparation system and method. The automatic grout preparation system comprises a material storage device, a water storage device, a first-stage stirring device, a deposition box, a second-stage stirring device and a grouting pump, wherein the material storage device is connected with the first-stage stirring device through an automatic material conveyingdevice, and the water storage device is connected with the first-stage stirring device through a water pump; and the first-stage stirring device is connected with the deposition box through a one-wayvalve, the deposition box is connected with the second-stage stirring device through a one-way valve, and the second-stage stirring device is connected with the grouting pump. The automatic grout preparation system and method have the beneficial effects that the uniformity and fluidity of granular grout are improved, sediments in the grout preparation process are easy to clean, the grout parameters in the grout preparation process can be accurately monitored, the automatic grout preparation system and method can be applied to the preparation of all kinds of granular grout materials, and the grout production yield and construction continuity in grouting engineering can be ensured.

Description

technical field [0001] The invention relates to the technical field of slurry preparation, in particular to an automatic slurry preparation system and a preparation method thereof. Background technique [0002] At present, grouting technology is widely used in various types of adverse geological disaster control and coal mine fire prevention. It uses a grouting pump to inject a certain proportion of grout into cracks, strata, and coal seam fire areas to make it diffuse, gel and cool down. Oxygen isolation, in order to achieve the purpose of strengthening the formation, preventing seepage and plugging and preventing fire. In grouting engineering, the preparation of grout is the premise and important production link of grouting construction. Due to the increasingly stringent requirements for engineering safety and ecological environment, the requirements for grouting effect of various projects are correspondingly increased, and the grouting effect is great. The extent depends...

AI Technical Summary

Problems solved by technology

[0004] 1. Insufficient stirring of the cement slurry, poor uniformity of the slurry, easy to separate water and precipitate during the mixing process and transportation process, and it is difficult to clean the sediment;

[0005] 2. The output of the existing preparation system is small, and the supply of grout is often in short supply when grouting is performed. However, when the output of grout is increased, the quality of the grout is usually not up to standard;

[0006] 3. The existing preparation system is only limited to the stirring of slurry, and often ignores the monitoring of parameters such as slurry density, slurry water separation rate and pulping output;

[0007] 4. The mixer in some preparation systems cannot be used for the preparation of ultrafine materials. In addition, if the mixer is damaged during the preparation process, it will inevitably cause the paralysis of the entire preparation system, affect the continuity of grouting construction, and greatly reduce the grouting rate.
