Submerged state premixed abrasive water jet cutting concrete impact of the main parameters of the relationship with the cutting depth

Transformation and maintenance of the project , often involving cutting of concrete structures , such as construction and mining . Currently, broken concrete cutting that traditional methods ─ ─ mechanical cutting , drawback of the method is time-consuming , laborious , inefficient and working environment pollution. With new technologies emerging cutting , water jet cutting are also numerous reports of broken concrete , but premixed abrasive water jet underwater ( in a submerged state ) cutting concrete materials research has not been reported , and the submerged state cutting technology for the transformation of flooded mine and  synthetic diamond powder  are of great significance , therefore , experimental research in the submerged state premixed abrasive water jet cutting concrete impact on the main parameters of the relationship with the cutting depth . Premixed  synthetic diamond  jet cutting concrete underwater test apparatus including premixed abrasive water jet generating system and the target object ( specimen ) mobile systems and nozzle clamping devices. Premixed abrasive jet generating system has a piston implementation stage three supercharged , the abrasive tank is placed among the high-pressure circuit , so that the abrasive and water mix to form abrasive water jet through the nozzle , the target object ( specimen ) mobile systems with DC motor driven screw drive , thyristor rectifier circuit by adjusting the output voltage to achieve speed .
