Background technique
The indoor ordinary triaxial test of rocks sample is the extremely important and conventional experiment of geotechnical engineering experimental field.When It is preceding to have had ordinary triaxial test system in more complete rocks sample chamber both at home and abroad, size, examination from sample The mode etc. of the type, load tested has more complete reasonable specification.But after the work of dress sample and test before testing Unloading sample work is all very complicated complexity, unloads sample work after especially testing.Due to needing completely to take out examination after test The sample destroyed after testing is taken pictures and is saved, sample destroy after can all have large volume of expansion, due to sample elasticity compared with It is small, it is destroyed when in the thicker rubber sleeve of thickness, being often stuck in rubber sleeve and can not take out because circumferential deformation is larger, or taking out The rubber sleeve to involve great expense, and spend very big energy and longer time.For this reason, it may be necessary to there is one kind quick, convenient, simple Single survey unloads sampling device and method to solve problems.
Summary of the invention
The present invention provides a kind of rocks normal triaxial to solve drawbacks described above and deficiency existing in the prior art Sampling device and its application method are unloaded in test,.
In order to solve the above technical problems, the present invention, which provides a kind of rocks ordinary triaxial test, unloads sampling device, including stand, Compression leg, casing, chassis and fixator;The stand includes steel loop, fixed frame and support rod, and the stand is inserted in the slot on chassis Interior, the compression leg is steel column of the front end with hard rubber pressure pad, and the casing is the rubber casing of bottom end closure, the chassis For the steel plate with slot, the fixator is inserted in fixed frame.
Further, the stand includes steel loop, fixed frame and support rod, the steel loop be it is hollow, there are three folders on outer ring The fixed frame that the support rod and four angles that angle is 90 degree are 90 degree.
Further, three support rods of the stand are inserted in three slots on chassis.
Further, there are 2 screw holes on each fixator, there is a fixator in each screw hole.
Further, the compression leg is the cylindrical steel column that diameter is slightly less than steel loop internal diameter, length about 10cm shorter than support rod, The compression leg front end is slightly larger than the rubber press pad of compression leg diameter with a diameter.
Further, the casing is cylinder-shaped rubber sleeve only open at one end, and internal diameter is more bigger than the internal diameter of sample.
Further, the chassis is rigid material, can be cylinder, square column or polygon prism, above there is insert matched with support rod Slot.
Further, the fixator front end is the Rubber end of semielliptical type, and centre is threaded steel column, and rear end is six sides Shape nut.
The present invention also provides the application methods that a kind of rocks normal triaxial unloads sampling device, which is characterized in that including following Step:
Step 1 first twists fixator outward, so that steel loop about 3-5mm is left in fixator end, compression leg is mentioned upwards To top;
The sample finished and rubber sleeve are lifted down from triaxial apparatus, the upper end of rubber sleeve are inserted under steel loop by step 2 End, and pressure pad is made to enter rubber sleeve and sample upper-end contact;
8 fixators are inwardly tightened, and casing are put into chassis middle position by step 3, and sample is fallen into In casing;
Step 4 taps compression leg upper end with hammer, compression leg is slowly knocked in rubber sleeve, until sample is fallen into casing;
Step 5 after sample falls into casing, sample is taken out, and fixator is unscrewed out of casing, removes rubber Set.
Compared with the existing technology, present invention advantageous effects achieved are as follows: one kind (class) rock provided by the invention Sampling device is unloaded in ordinary triaxial test, can be with the simple and convenient quick sample set for realizing rocks ordinary triaxial test using the device Separation, and only need one man operation, it is no longer necessary to more people together often scratch by separation test and rubber sleeve, conventional method Hand, and destroy integrality when sample takes out.Pressure pad and casing of the invention can be effectively protected after sample destroys and be removed Integrality.In addition, this method is easy to operate the present invention also provides the application method for unloading sampling device, it is easy to use.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention Technical solution, and not intended to limit the protection scope of the present invention.
As shown in figs. 1-7, the present invention provides one kind (class) rock ordinary triaxial test and unloads sampling device, including stand 1, compression leg 2, casing 3, chassis 4 and fixator 5;The stand includes steel loop 101, fixed frame 102 and support rod 103, and the stand is inserted in In the slot 401 on chassis, the compression leg is steel column of the front end with hard rubber pressure pad 201, and the casing is bottom end closure Rubber casing, the chassis are the steel plate with slot, and the fixator is inserted in the screw hole of fixed frame.
The stand includes steel loop, fixed frame and support rod, and it there are three angle is 90 degree on outer ring that the steel loop, which is hollow, Support rod and four angles be 90 degree fixed frame.Three support rods of the stand are inserted in three slots on chassis.Institute Stating has 2 screw holes on each fixator, there is a fixator in each screw hole.The compression leg be diameter be slightly less than steel loop internal diameter, The cylindrical steel column of length about 10cm shorter than support rod, the compression leg front end are slightly larger than the rubber of compression leg diameter with a diameter Pressure pad.The casing is cylinder-shaped rubber sleeve only open at one end, and internal diameter is more bigger than the internal diameter of sample.The chassis is rigidity material Material can be cylinder, square column or polygon prism, above there is slot matched with support rod.The fixator front end is the rubber of semielliptical type Rubber head, centre are threaded steel column, and rear end is hex nut.
