Abstract

The invention discloses a flexible plastic quick grouting hole sealing device and method. The device is mainly composed of an umbrella buckle type plugging device, a slotting flexible plastic grouting pipeline and a double-cone pipe connector device. The initial grout pressure in pipes is positively stored in a sealed mode through the differential flow of grout fed into and discharged out of the grouting pipes, and the processes of automatic pushing out, spreading and plugging of a convex angle umbrella buckle are completed. A flexible plastic pipe capable of being coiled is adopted to be inserted into a drill hole at a time, and the primary quick hole sealing operation requirement is met. According to the flexible plastic quick grouting hole sealing device and method, the process of traditional hole sealing operation is simplified, operation is convenient and quick, the cost is low, and the device and the method are novel hole sealing device and method which have wide application and popularization value.

Description

technical field

[0001] The invention discloses a flexible plastic fast grouting sealing device and method, which is mainly used for the sealing operation of coal and rock drilling, for the static pressure (hydraulic fracturing) and dynamic pressure ( Hydraulic pulsation, hydraulic jet) cracking, anti-reflection, pressure relief, and blasting in coal and rock drilling (common charge blasting, liquid-filled pressure blasting, etc.) have good hole sealing effects. Background technique

[0002] The pre-cracking control of the hard roof of the coal seam, the high stress relief transfer and dynamic load prevention and control of the coal seam in the deep mine, the efficient drainage of the gas-containing coal seam, etc. are all the main technical problems faced by the safe and efficient mining of modern mines in my country. Under the condition of hard and difficult roof, the influence on the safety production of coal mine is more prominent. Aiming at such outstanding problems in m...
