Said invention also provides a method for testing crumbling process of rock by using three metal mesh cylinders with different diameter sizes of 10mm, 5mm and 2mm and three electronic balances, the above mentioned metal mesh cylinders are respectively hung on said three electronic balances, and provides the concrete steps for implementing said invention.
Description
Technical field rock property experimental technique field
Background technology has two kinds about the test of disaggregation both at home and abroad at present: slake-durability test and common slaking test.The standard of anti-slaking test method mainly contains the slake-durability test method in the Chinese Standard for test methods of engineering rock masses (GB/T50266-99) of the method for ISRM (ISRM) suggestion in 1979 and issue in 1999, these two kinds of testing regulationss are roughly the same, all be 105 ℃～110 ℃ oven dry coolings in 2～6 hours down with test specimen, putting into the aperture is the wire netting cylinder of 2mm, insert in the water with the speed of 20r/min and rotated 10 minutes, take out sample oven dry weighing, circulation is afterwards done once, obtains the anti-disintegration index of rock with the dries quantity and the residual sample dries quantity of raw sample at last.The slake-durability process of the test has strong outer energetic disturbance, makes disaggregation fully and thoroughly, can draw a relatively more conservative disintegrative design objective, meets the demand of design, but and do not meet the actual disintegrating procedue of rock;
Common slaking test is common in scientific research project and the test of special engineering rock property.Method commonly used is to leave standstill rock sample in the entry or be placed in the air, until rock sample disintegration (one or many disintegration) fully, with rock sample initial mass and disintegration fully afterwards residual mass obtain rock sample disintegration rate.The more realistic disintegration situation of the process of the test of common slaking test, but this test can't be to the various failure mode (cement pastes of rock, clastic, dust shape and chunky shape) process be quantitatively described, be unfavorable for disaggregation form and disintegration Mechanism analysis and explanation.
In a word, above-mentioned present two kinds of disaggregation test methods, the former process of the test has strong outer energetic disturbance, make disaggregation fully with thorough, can draw a relatively conservative disintegrative design objective, meet the demand of design, but and do not meet the actual disintegrating procedue of rock; The more realistic disintegration situation of latter's process of the test, but this test can't be quantitatively described the process of the various failure modes of rock (cement paste, clastic, dust shape and chunky shape), is unfavorable for disaggregation form and disintegration Mechanism analysis and explanation.Two kinds of methods all can not satisfy the requirement of describing the disaggregation process quantitatively.
Summary of the invention the invention provides a kind of can being quantitatively described the various disintegration failure mode of rock process, real time record disaggregation speed, whole process writes down disintegration time and disintegration feature, helps the rock static state disintegrating procedue instrument of disaggregation Analysis on Mechanism and explanation.It is the wire netting cylinder of 10mm that rock sample is placed mesh diameter, put the wire netting cylinder that mesh diameter is 5mm at this wire netting cylinder sleeve, again the wire netting cylinder sleeve in 5mm aperture is put the wire netting cylinder that the aperture is 2mm, each wire netting cylinder is suspended on respectively on three electronic balances, and each wire netting cylinder can not contact.In the aqueous solution with wire netting cylinder immersion glass test cylinder (jar), at this moment begin reading of each moment three electronic balance of omnidistance record, get final product the disintegrating procedue of the various disintegration failure modes of quantitative description rock (cement paste, clastic, dust shape and chunky shape).At mesh diameter is that the bottom surface of the wire netting cylinder of 10mm has the metal leg, can make the rock sample disintegration face sky, and the disintegration thing drops smoothly.
Ultimate principle and technology: according to the disaggregation test principle, estimating disaggregation has three indexs: disintegration time; Disintegration feature (disintegrating procedue phenomenon); Disintegration rate.Adopt rock static state disintegrating procedue instrument to obtain these indexs by real-time quantitative.
Rock static state disintegrating procedue instrument mainly is made up of disintegration tester part and measurement recording section.
Disintegration tester is nested with by three wire netting cylinders 5,6 and 7 and forms, and wire netting cylinder 5,6 and 7 is suspended on three electronic balances 8 with connecting rod 9 respectively.Wire netting cylinder 5,6 and 7 mesh diameter are respectively 2mm, 5mm and 10mm, and each wire netting cylinder does not contact, and each side of wire netting cylinder and bottom surface are wire side.Because being the cement paste disintegration during less than 2mm, disintegration thing size destroys, disintegration thing size is that the clastic disintegration destroys between 2mm and 5mm the time, disintegration thing size is that the disintegration of dust shape destroys between 5mm and 10mm the time, disintegration thing size during greater than 10mm for the chunky shape disintegration destroys, so the mesh diameter of three wire netting cylinders is chosen as 2mm, 5mm and 10mm.When slaking test begins, the wire netting cylinder should be immersed in the aqueous solution, rock sample must be submerged, and wire netting cylinder 5 bottom surfaces must not contact with glass test cylinder (jar) 3.At mesh diameter is that the bottom surface of the wire netting cylinder 7 of 10mm is welded with the metal leg, and rock sample is placed on the metal leg, makes the rock sample disintegration face sky, and the disintegration thing can drop smoothly.
Measuring recording section mainly is three electronic balances, stopwatch and video cameras.Three electronic balances write down the variation of each wire netting cylinder quality in the disaggregation process, write down disintegration time with stopwatch, the camera record disintegrating procedue.According to each reading constantly of electronic balance, can calculate each disintegration rate constantly in the disaggregation process, the process that the various disintegration failure modes of quantitative description take place.
Description of drawings 1: rock sample; 2: aqueous solution; 3: the glass test cylinder (jar); 4: liquid level; 5: mesh diameter is the wire netting cylinder of 2mm; 6: mesh diameter is the wire netting cylinder of 5mm; 7: mesh diameter is the wire netting cylinder of 10mm; 8: electronic balance (precision 0.01g); 9: connecting rod; 10: net bucket bottom surface leg
Embodiment 1. is put into constant temperature oven with rock sample, makes rock temperature reach 105 ℃ with 5 ℃/2 hours the speed that heat, and then rock is placed on natural cooling in the exsiccator; Perhaps directly begin test with a certain initial water content sample.
2. rock sample is put on the bottom surface leg that the aperture is a 10mm wire netting cylinder 7, claimed its quality with electronic balance 8; Weigh up the quality that the aperture is 5mm and 2mm wire netting cylinder 6 and 5 with spring balance respectively.Net bucket with three apertures is suspended on the electronic balance 8 that is fixed on the instrument stand respectively.It is the wire netting cylinder 7 of 10mm that rock sample places the aperture, with the aperture is that to place the aperture be the wire netting cylinder 6 of 5mm for the wire netting cylinder 7 of 10mm, with the aperture be again the wire netting cylinder 6 of 5mm to place the aperture be the wire netting cylinder 5 of 2mm, each net bucket can not contact.
3. the wire netting cylinder that is nested with is immersed and fill in the glass test cylinder (jar) 3 of aqueous solution, open video camera simultaneously, the reading that picks up counting, the variation of writing down three electronic balance 8 readings.By the time when three electronic balance 8 readings change less than 0.01g/h, remaining rock sample in the wire netting cylinder 7 is taken out, put into constant temperature oven or place air to dry, repeat 1～3 step, till the complete disintegration of rock sample.
