Technical field
The utility model relates to a kind of rock softening plant; Particularly relate to a kind of test that is used for field rock softening intensities such as Hydraulic and Hydro-Power Engineering, underground works, traffic engineering, petroleum engineering, the pressure type rock softening plant of especially measuring to the rock softening intensity at different excavation off-load subregions position.
Background technology
Under the prior art condition; Rock mass softening intensity method of testing is at first rock to be processed into diameter 50mm, and the test specimen of length 100mm adopts bowssening to make the test specimen state that reaches capacity then; Carry out uniaxial compressive strength test again, the result who obtains is exactly the rock strength after softening; Through contrasting the compressive strength of the rock sample under natural aqueous rate or the drying regime, can obtain coefficient of softing.What the rock softening intensity that this method obtains was corresponding is the softening intensity after stress obtains removing in the rock.In fact, even be in the rock under the underground water state of saturation throughout the year, its intensity is owing to receive the influence of terrestrial stress, and the rock strength softening effect is significantly less than the softening effect after the stress relieving.For remedying in the existing softening test measuring technology in the rock saturation history stress relieving to the influence of rock strength characteristic, proposition can be considered the rock of the environmental stress influence saturated softening plant that soaks.
The utility model content
The technical matters that the utility model will solve is to not reflecting the weak point of stress to the softening properties influence in the existing saturated softening process of rock, to provide a kind of and can consider stress influence and the softening pressure type rock softening plant of batch processing rock sample.
In order to solve the problems of the technologies described above; The pressure type rock softening plant that the utility model provides; At least one test specimen base is set on the container floor of airtight container; Described test specimen base is provided with permeable hole and is connected with the water outlet pipe network; In described airtight container, be provided with the test specimen top cover that equates and align in twos setting with described test specimen base quantity; Each described test specimen top cover is provided with the inlet opening and is connected with the water inlet pipe network, and the two ends of rock sample are fixedly mounted between described test specimen base and the described test specimen top cover and the side outer wall of rock sample is enclosed with one deck and seals mantle the bore seal of described rock sample and described airtight container is separated, and described airtight container is connected with high pressure water intaking valve and tensimeter.
Described airtight container is the cylindrical seal container; Described cylindrical seal container is made up of container floor, container side wall and vessel top cover plate; And between described vessel top cover plate and described container side wall, be provided with rubber seal, be tightly connected through fastening bolt.
The internal diameter of described cylindrical seal container is that 700mm, free height are 240mm, and described test specimen base is 30, and the diameter of each described test specimen base is 50mm.
Described sealing mantle is a rubber diaphragm.
Adopt the pressure type rock softening plant of technique scheme; The test specimen top cover is provided with the inlet opening and is connected with the water inlet pipe network; The saturated required water of rock sample enters into rock sample through the water inlet pipe network and rock is soaked softening; And, between vessel top cover plate and the container side wall rubber seal is set through the outflow of water outlet pipe network, through fastening bolt container is connected and sealed; To bear the water pressure that enters into airtight container through the high pressure water intaking valve, the pressure of the rock sample in the airtight container is surveyed by tensimeter and is read to control with the high pressure water intaking valve.
The utility model utilizes the rubber diaphragm that wraps up on the rock sample that the water separation in rock sample and the airtight container is come; Water pressure in the airtight container transfers the pressure on the rock sample through rubber diaphragm; Realization applies the stress of different stage to rock sample, with the influence of reflection stress to the rock softening performance.The water of softening rock test specimen is with separate to the water body of rock sample stress application, and the water of softening rock test specimen is low-pressure water, and is water under high pressure to the water in the container of rock sample stress application.Because the high pressure water intaking valve is set, after the pressure in the airtight container reaches design load, close the high pressure water intaking valve, can carry out the long-term softening test of rock sample.This device is reasonable in design, simple in structure, easy to operate.
In sum, the utility model utilizes the water pressure in the airtight container to realize the control to softening rock test specimen stress through the rock sample parcel rubber diaphragm in softening container, and the water body of softening rock test specimen and the water body of stress application are separate.Owing to be provided with the high pressure water intaking valve, can under closing the high-pressure hydraulic pump situation, keep the pressure in the container for a long time simultaneously.This device provides the foundation for further improving rock softening properties measuring technology and method.
