The invention relates to an impact rock breaking test bed for simulating rock stratum confining pressure. The impact rock breaking test bed comprises a base, a sample box, a confining pressure loadingdevice, a cutting device, a water circulation system, a hoisting system and a monitoring system, and a supporting frame is arranged on the base; the sample box is arranged on the base; the confiningpressure loading device is used for applying bidirectional confining pressure to the rock mass sample; the cutting device is used for milling and cutting a rock mass sample in the impact rock breakingtest; the water circulation system is used for guiding water to a cutting position in an impact rock breaking test; the hoisting system is used for hoisting a rock mass sample into the sample box; the monitoring system is used for monitoring a driving part of the confining pressure loading device, a driving part of the cutting device, a water pump of the water circulation system and a driving part of the hoisting system. The impact rock breaking test bed can perform a simulation test of rock breaking of the milling wheel of the double-wheel slot milling machine, can perform a rock breaking test of multiple cutting pick arrangement modes in a single period under the condition of no confining pressure, and then assists the improvement and optimization design of the slot milling machine.
Description
technical field [0001] The invention relates to the technical field of impact rock-breaking tests, in particular to an impact rock-breaking test bench for simulating confining pressure of rock formations. Background technique [0002] The underground continuous wall is a continuous wall constructed below the ground for water interception, seepage prevention, soil retaining and load bearing. The double-wheel slot milling machine is the core equipment in the construction of underground diaphragm walls, and the arrangement method of its milling wheel picks is still monopolized by foreign countries. The premise of optimizing the way of milling wheel tooth arrangement to improve the efficiency of slot milling machine is to study the rock breaking efficiency of the tooth arrangement system. [0003] Rock milling and crushing is a complex process of multiple interactions between the pick and the rock during the rotation of the milling wheel, such as impact, extrusion and shearing....
