The utility model belongs to the technical field of architectural engineering technology and specifically relates to a detect container of piling up that water sand mixture suddenly gushes in -processpressure variation, including passageway experiment chamber, passageway experiment chamber's one end is connected with first high -pressure reagent cabin, the one end that passageway experiment chamber was kept away from in first high -pressure reagent cabin is connected with a coupling hose, a coupling hose keeps away from the one end and reagent tester intercommunication in first high -pressurereagent cabin, passageway experiment chamber's the other end and second high pressure test chamber, second high pressure test chamber is provided with electron pressure -bearing switch with passageway experiment chamber's junction, this detect container of piling up that water sand mixture suddenly gushes in -process pressure variation has realized detecting the function that the water sand mixture suddenly gushes in -process pressure variation, it pursues the formation that the water sand mixture suddenly gushes to be convenient for the experimenter, take place, the development mechanism, summarize the characteristic that different pressure water sand mixtures suddenly gush.
