Gushing water is mud excavation analogue means suddenly

The utility model relates to a gushing water is mud excavation analogue means suddenly, including base, test cavity, vertical pressor pressure device and water inlet, test cavity one side is equippedwith two excavation entrys, lies in the last downside of test cavity respectively, goes into orad intracavity excavation tunnel through the excavation of upside or downside, and test cavity inside isprovided with the similar material of rock mass and karst and dissolves the chamber, the similar material of rock mass dissolves the karst in the chamber and surrounds, the test cavity is located on the base, pressure device locates the test cavity top, still be equipped with the water inlet on the test cavity, the utility model discloses rigidity is big, intensity is high, the leakproofness is better, measured data is accurate, can simulate out the law of the abrupt mud of karst tunnel excavation in -process gushing water under different positions, the difference condition of filling and thedifferent pressure conditio
