Description
Technical Field

Background
Static breaker is called static breaker for short, which belongs to chemical physical rock breaking method. The crushing method is to drill holes on a crushed body (rock or concrete) and fill the holes with static crushing agent slurry; as the hydration reaction proceeds, expansion and hardening simultaneously occur, and an expansion pressure is generated, thereby realizing cracking and breaking of the crushed body. The static crushing method has the advantages of no vibration, no noise, no flying stone, no dust and no pollution, and is suitable for the recovery of noble stone materials such as towns, plant reconstruction and expansion, building demolition, granite, marble and the like and the crushing construction of other special occasions.
Research shows that the higher the water temperature is, the larger the diameter of the drilled hole is, the larger the expansion pressure generated by the crushing agent is, the crushing time is greatly reduced, the crushing efficiency is high, and the defect of the spray hole is brought. The jet hole is a phenomenon in which the breaker slurry filled in the drill hole is suddenly ejected from the orifice at the initial stage of hydration. This is due to the fact that the static breaker gives off a lot of heat at the early stage of hydration, which results in an increase in slurry temperature. When the temperature rises to the boiling point of water, redundant mixing water which is not hydrated in the slurry is gasified rapidly to generate a large amount of steam which is not lost and accumulated in the slurry to generate pressure; the slurry is ejected under pressure. The surface area of the large-aperture (aperture exceeds 50 and m) drilled holes is relatively small in volume of the slurry filled with the breaker, heat generated by hydration reaction is easy to accumulate in the slurry, the heat in turn promotes hydration reaction, the temperature is rapidly increased, and redundant and unhydrated water in the slurry is rapidly gasified and boiled, so that a blowout phenomenon occurs.
In order to get rid of the restriction of the jet orifice phenomenon on the crushing effect of the large-diameter static breaker, and simultaneously enable the direction of crack propagation to realize artificial control, a directional fracturing rock breaking device which is suitable for large-aperture construction, improves the water injection temperature and can inhibit jet orifices is required to be developed.
