A Downhole Movable Grouting Method

Abstract

The invention discloses a downhole movable slurry casting device and method. The device comprises a caterpillar-band chassis mechanism, a slurry casting mechanism and a monitoring module; the slurry casting mechanism comprises a feeding structure and a slurry preparing mechanism, the caterpillar-band chassis mechanism comprises a chassis, a caterpillar band and a caterpillar band driving module, and the monitoring module comprises a main controller, a feeding monitoring module, a water inlet monitoring module, a motor power supply control module, a first wireless radio frequency module and a liquid crystal touch screen. The method comprises the following steps of 1, building a mine map and moving the caterpillar-band chassis mechanism; 2, checking and connecting the slurry casting mechanism; 3, preparing and delivering the slurry through the slurry casting mechanism. The downhole movable slurry casting device is reasonable in design and easy to operate; the movement of the caterpillar-band chassis mechanism drives the slurry casting device to move, and labor and material resources are saved; by monitoring the aqueous slurry in real time, the concentration and mass of the slurry areensured, and the practicability is high.

Description

Technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a movable underground grouting method. Background technique [0002] At present, the fire-prevention grouting device has been widely used in underground coal mine fire-prevention work, and it has become an indispensable equipment for coal fire prevention and control. The common grouting device is usually moved to the fire area in the form of vehicle or hoisting due to its own weight and inconvenience, which consumes manpower and material resources and greatly affects the process of extinguishing grouting. In addition, the feeding method mainly adopts the mechanical feeding and water ratio method to make slurry and carry out the slurry transportation. When the slurry transportation volume needs to be changed, the extinguishing agent material supply amount is often changed while ensuring the success. The concentration of the slurry meets the fire-fighting r...

Problems solved by technology

Due to its heavy weight and inconvenient movement, common grouting devices are usually moved to the fire area in the form of vehicle or hoisting, which consumes manpower and material resources and greatly affects the process of fire extinguishing and grouting

In addition, the feeding method mainly adopts the mechanical feeding and water ratio method to make pulp and carry out slurry transportation. When it is necessary to change the slurry delivery volume, it is often necessary to change the feed volume of the fire extinguishing agent at the same time, in order to ensure the cost The concentration of the slurry meets the fire extinguishing requirements on site. Workers usually control the water intake by feeling, which will make it difficult to match the corresponding water intake in time, thus affecting the concentration and use effect of the slurry, and affecting the smooth development of fire prevention and extinguishing work.

[0003] Therefore, in order to solve the problems such as the inconvenient movement of the grouting devices currently on the market during transportation and the non-standard water-to-material ratio in the pulping process, there is currently a lack of a mobile grouting method with a simple structure and a reasonable design. The movement of the grouting device is driven by the movement of the crawler base mechanism and saves manpower and material resources. Through real-time monitoring of the water material, the concentration and quality of the slurry are ensured, and the monitoring and control of the batching process is realized, which will greatly improve the fire prevention and grouting.
