Description
Technical field
The utility model relates to a kind of Geotechnical Engineering experimental provision, particularly relates to a kind of static pressure type three axle saturator.
Background technology
Indoor triaxial test is technological means conventional in Geotechnical Engineering construction and scientific research, and being obtain reliable Rock And Soil physical and mechanical parameter, is the important evidence that geotechnical engineering design and construction provide correct decisions.Code requirement for the Geotechnical Engineering of carrying out under complex geological condition, obtain rock mechanical parameter index time, must according to the result of indoor triaxial test.At present, conventional chambers triaxial test sample is cylindrical sample, and when carrying out sample and being saturated, what usually adopt is the saturator including base, fixed head, footstock, clamping plate, pull bar, permeable stone, circle mould and lock ring.
This saturator can be used for the saturated preparation of most of three axle rock sample/earth samples, but for similar expansive rock/native inside, there is Expansion Potential and soil body volume change then exists by the very large great soil group of moisture content immersion effect the shortcoming being difficult to overcome: (1) expansive rock/native mineralogical composition is based on smectite, Rock And Soil volume is remarkable by moisture variable effect, the free swelling rate of strong swelling soil can up to 160%, inherent bulging force can up to 1. 8MPa, carry out saturated according to common saturator to three axle samples, be subject to deformation constrain, bulging force can cause the deformed damaged of saturator, meanwhile, rock/native three axle sample peripheries contact imbibition with water at first, because being subject to deformation constrain, make the infiltration coefficient of expansive rock/soil sample that perviousness is low originally lower, thus cause whole sample immersion saturated to be difficult to evenly, and saturated needs for a long time.(2) expansive rock/soil sample adopting usual saturator to prepare, because being subject to deformation constrain, in saturator, the volume of the rock/soil sample of saturated front and back and density are known, and once take out from saturator, put into triaxial test indoor when testing, scholar's sample changes into by India rubber modular constraint from the constraint being subject to circular lobe mould, Expansion Potential is released, soil sample can continue to produce dilatational strain in the process of triaxial shear test, the original state of sample is not only caused to change, but also the change of the sample body of shear test can be caused to be difficult to distinguish with the dilatational strain of sample self, test findings is caused to analyze.Therefore, must develop one can allow expansive rock/soil sample fully to inhale water saturated saturator, and take out after stable until its volumetric expansion, again cut and recover original three axle sample sizes, recalculate the initial density of rock/soil sample again, then carry out triaxial shear test, the defect of above-mentioned traditional saturator can be overcome, meet the saturated preparation of expansive rock/native three axle samples.
At present, in practical operation, also have and do not adopt saturator and directly naked for three axle rock/soil samples of the machine-shaping water that is placed in carried out saturated method, though the expansion of rock/soil sample is unfettered in the method, but because expansive rock/soil sample has many fissurities and water-disintegration, there will be sample disintegration or obscission in the process of immersion saturated, cause specimen breakdown.
Utility model content
Problem to be solved in the utility model is to provide one can make rock/earth sample free expansion to saturated, the stabilization that absorbs water, and not easy disintegrating, easy to operate static pressure type three axle saturator.
The utility model static pressure type three axle saturator, comprise base, top cover, permeable stone, circle mould, pull bar, described base and top cover are provided with second order through hole along respective axis respectively, are provided with connecting hole around respective flange correspondence; Described permeable stone is arranged in hole, base rank, and described round mould lower end is placed in hole, base rank, and circle mould lower end and permeable stone upper surface attach, and described round mould upper end is placed in hole, top cover rank; Described pull bar correspondence through the connecting hole of top cover and base and tightening nut by base, permeable stone, circle mould, top cover maintenance integrally; Top cover upper surface is upwards provided with body along its axis, also comprises a pressure head, and described crimp body xsect is identical with inboard wall of tube body xsect, can assign in body.
The utility model static pressure type three axle saturator, also comprises a cuff, and described cuff is in circle mould outside surface banding circle mould.
The utility model static pressure type three axle saturator, wherein said base and top cover are provided with second order through hole for circular along respective axis respectively.
The utility model static pressure type three axle saturator, it is square that wherein said base and top cover are provided with second order through hole along respective axis respectively.
The utility model static pressure type three axle saturator, wherein said pressure head top is provided with flange.
The beneficial effects of the utility model are: a kind of static pressure type three axle saturator, owing to have employed the pressure head that can slide along inboard wall of tube body, therefore the volume of saturator can the self-control along with the change of ground volume, even if in rock/earth sample immersion saturated process, the damage of saturator is also there will not be to be out of shape; In addition because the periphery of rock/earth sample and saturator attach, so also there will not be the stripping of sample periphery always; Simultaneously because the round mould shape of saturator is fixed, so the xsect of rock/earth sample can not change when immersion saturated, only can be elongated in length, therefore only need intercept from length and need can not obtain three original axle sample sizes circumferentially cutting, rapidly and efficiently.The second order through hole of this saturator both can be chosen as circle and also can be chosen as square, had not only enriched the kind of saturator, and had had in the manufacture craft of saturator and select more flexibly; Its pressure head top is provided with flange, eliminates pressure head of knowing clearly and falls into hidden danger in saturator cavity, and be convenient to the control of user to it.
