The invention relates to the technical field of colliery water disaster prevention and treatment, in particular to a grouting device for the colliery water disaster prevention and treatment. The device comprises a grouting pipe, wherein the side wall of the grouting pipe is provided with a plurality of one-way electromagnetic valves in sequence from top to bottom, and the top of the grouting pipeis connected with a grouting flexible pipe; the upper portion of the grouting pipe is rotationally connected with a supporting plate arranged horizontally, and two ends of the supporting plate are fixedly connected with telescopic columns arranged vertically; the portion, located at the upper portion of the supporting plate, of the grouting pipe is fixedly sleeved with a first gear, the right sideof the first gear is meshed with a second gear, the lower side of the second gear fixedly connected with a rotating shaft, the rotating shaft is connected with a motor, and the motor is fixedly arranged on the supporting plate; a grouting liquid enters interspace from the one-way electromagnetic valves for performing the grouting, but cannot adversely flow into the grouting pipe, so that the grouting is achieved successfully; the first gear drives the grouting pipe to rotate, and the telescopic columns drive the supporting plate to descend, so that the grouting pipe descends and rotates simultaneously, and the convenient placement of the grouting pipe is achieved.
Description
technical field [0001] The invention relates to the technical field of coal mine water disaster prevention and control, in particular to a grouting device for coal mine water disaster prevention and control. Background technique [0002] Coal mine floods affect the progress and quality of mine construction, worsen the working environment of workers, increase the drainage facilities and drainage costs of mines, and bring unsafe factors to coal mine production. In severe cases, well flooding accidents even occur, causing major loss of life and property. Losses, in the process of coal mining, it is very easy to communicate with water accumulation in old cellars, water leakage accidents in car-making mines, and water damage accidents in coal mines will also lead to erosion and weakening of surrounding rocks, induce secondary disasters, damage water resources, and reduce resource recovery rate, tons The cost of coal drainage remains high, and the hydrogeological conditions of my co...
