Abstract
The utility model discloses a water absorption test device for a rock capable of disintegrating when meeting water, and aims at overcoming the weaknesses in the prior art. The test device comprises a soft material for wrapping the rock capable of disintegrating when meeting the water, and a water storage vessel, wherein the soft material is provided with a waterproof area and a water permeable area, in a test, the rock capable of disintegrating when meeting the water wraps the waterproof area, and the waterproof area is arranged above the water permeable area. The test device is scientific, practical, simple in structure and easy to implement. When water absorption test device is used for detecting the water absorption of the rock capable of disintegrating when meeting the water, the test pertinence is strong, the convenience in operation is realized, the test time is short, and the efficiency is high.
Description
Technical field
The utility model relates to a kind of chance water crumbling rock water absorption test device.This test unit is applicable to foundation works and Geotechnical Engineering roadbed technical field.The rock water absorption test that the method is carried out, for meeting this special circumstances of water crumbling rock.
Background technology
Rock water absorptivity is the performance that rock absorbs moisture, and characterizing the absorptive quantitative target of rock has: water-intake rate, saturated water absorption and saturation coefficient.Rock water absorptivity is one of rock important physical index.For the correct deformation and failure rule of grasping rock, the stability of rock is made to analysis and the evaluation of conforming to the actual situation, for engineering design, reinforcing, buildings type selecting and selection of construction method etc. provide parameter and foundation.
In < < Standard for test methods of engineering rock masses GB/T50266 > >, about rock water absorption test, there is following requirement: (1) rock water-intake rate adopts free bowssening to measure.(2) rock saturated water absorption adopts boiling method or vacuum suction method to be determined at mensuration.(3) should adopt weighing method in water to measure rock block density when rock water-intake rate and saturated water absorption.(4) this test is applicable to meet the rock of not disintegration of water.
Meet water crumbling rock and refer to and meet the rock that water will disintegration becomes fragment, in existing method, do not have scientific and reasonablely for testing, to meet the absorptive test unit of water crumbling rock.
Summary of the invention
For defect or the deficiency of prior art, the purpose of this utility model is to provide a kind of chance water crumbling rock water absorption test device.
For this reason, the chance water crumbling rock water absorption test device that the utility model provides comprises the flexible material of water container and parcel chance water crumbling rock, described flexible material is provided with impervious zone and permeable district, meet water crumbling rock and be wrapped in impervious zone, and permeable district is positioned at top, impervious zone.
The size shape that described parcel is met the flexible material of water crumbling rock is that the length of side is 550-650mm square.
Described impervious zone is toroidal.
The radius of described impervious zone is 70-90mm.
Described permeable district offers a plurality of permeable holes.
Described permeable district is circular, and the inside and outside semidiameter of this annulus is 20-30mm.
Test unit science of the present utility model, practicality, and simple in structure, be easy to realize.While utilizing the water absorptivity of this test unit end-on water crumbling rock to detect, test with strong points, easy to operate, the fugitive rate of test period is high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the utility model is further explained to explanation.
Fig. 1 tests for this structural representation that novel parcel is met the flexible material of water crumbling rock;
Fig. 2 is the use view that the utility model is met water crumbling rock water absorption test device.
Specific implementation method
As depicted in figs. 1 and 2, the utility model test apparatus comprises the flexible material 1 of water container 4 and parcel chance water crumbling rock, and described flexible material 1 is provided with impervious zone 2 and permeable district 3, during test, meet water crumbling rock and be wrapped in impervious zone 2, and impervious zone 2 is positioned at 3 tops, permeable district.Flexible material of the present utility model can be selected transparent plastic paper.
The method that the water absorptivity of employing the utility model device end-on water crumbling rock detects comprises the following steps:
Water-intake rate method of testing:
Step 1, sampling: test specimen is preferably the perfectly round shape sillar of length of side 40-60mm.The quantity of every group of test test specimen must not be less than individual, thereby avoids the misoperation in process of the test.Described test should be usingd the mean value of three parallel experiment results as meeting the absorptive measurement index of water crumbling rock.
Step 2, mark test specimen: form of the development degree of the rock title of every group of test specimen, color, mineralogical composition, structure, rate of decay, cementing matter character, joint fissure and distribution thereof, test specimen etc. is described.
Step 3, test specimen are dried: test specimen is placed in baking oven, at 105-110 ℃ of temperature, dries 24h, taking-up is put into exsiccator and is cooled to room temperature.
Step 4, parcel test specimen are also weighed: cooled test specimen is encased with dry polybag, and seal with cord, on polybag, (the following position of the above cord of test specimen) pricked appropriate pore, and m then weighs
s.
Step 5, saturated test specimen: will put into than the bulky beaker of test specimens with the sample of polybag parcel, and with hook, the test specimen of polybag parcel is hung in beaker, be first filled to below the above cord of height of specimen.Test specimen freely absorbs water after 48h in water, take out polybag and be also stained with polybag outside surface moisture, then (m has weighed to use filter paper after moistening
1) block plastic bag mouth, the superfluous water in polybag is flowed out, wait while no longer there are flowing out, measure the quality m that polybag, the filter paper that speckles with filter residue and the saturated soil body have altogether
o.
Water-intake rate computing formula is:
Saturated water absorption test:
Operation above-mentioned steps one is to step 4;
Then will put into than the bulky beaker of test specimens with the sample of polybag parcel, and with hook, the test specimen of polybag parcel is hung in beaker, be first filled to below the above cord of height of specimen.Vacuum pressure meter reading is preferably 100kPa, until overflow without bubble, but always the time of bleeding must not be less than 4h.Test specimen through vacuum suction should be placed in former container, and standing 4h under atmospheric pressure takes out polybag and is also stained with polybag outside surface moisture, then (m has weighed to use filter paper after moistening
1) block plastic bag mouth, the superfluous water in polybag is flowed out, wait while no longer there are flowing out, measure the quality m that polybag, the filter paper that speckles with filter residue and the saturated soil body have altogether
p.
Saturated water absorption computing formula:
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses, the simple change of the technical scheme that can obtain apparently or equivalence are replaced and are all fallen in protection domain of the present utility model.
