Abstract
The invention relates to a measuring instrument for the rate of specific gravity of coarse-grained soil. The measuring instrument is composed of a main body desk frame, an electronic balance, a water container, a metal mesh basket used for containing the coarse-grained soil and the like, wherein the main body desk frame is composed of a lifting main shaft, a sample hanging hook frame, a water container support frame, a rotation handle and a locking handle; and the sample hanging hook frame is connected with the lifting main shaft, the lifting main shaft is connected with the rotation handle, and the water container support frame is connected with the lifting main shaft and the locking handle by a connecting piece. When the locking handle is in an open position, only the sample hanging hook frame does up-and-down movement through the lifting main shaft by rotating the rotation handle of the main body desk frame; when the locking handle is in a locked position, the sample hanging hook frame and the water container support frame synchronously do the up-and-down movement through the lifting main shaft by rotating the rotation handle of the main body desk frame. The measuring instrument has unique design, small volume and is easy to operate. With the adoption of the measuring instrument, the specific gravity of the coarse-grained soil can be fast and effectively measured.
Description
Technical field:
The present invention relates to a kind ofly in soil test, measure the proportion device of soil.Relate in particular to the specific weight determine device of coarse-grained soil.
Background technology:
Along with developing rapidly of civil engineering technology; Reliability that civil engineering material is detected and rapid assay methods and instrument and equipment have proposed corresponding requirement; This promoted the traditional experiment technology development and progress, especially boosting the developing rapidly of soil test technique level.The method of traditional test coarse-grained soil proportion has siphon tube method, floating title method; The test accuracy of siphon tube method is lower; And the test operation of floating title method is complicated and meticulous, adopts the buoyancy appearance exactly greatly to improve the deficiency of these two kinds of test methods, has improved test efficiency.This test method is to be accompanied by the development of wide range, high-precision electronic balance manufacturing technology and to produce.
Summary of the invention
The present invention is directed to the deficiency that in traditional soil test coarse-grained soil specific gravity test instrument is existed, and a kind of instrument to the coarse-grained soil specific weight determine of invention.It is a theoretical foundation with Archimedes's the law of buoyancy, can measure the rate of specific gravity of coarse-grained soil simply, accurately.
The buoyancy appearance of first technical scheme according to the present invention, it is made up of main body stand and large range high precision balance, water container, Metal net basket etc.Said main body stand is by the up-down main shaft, hangs sample hook housing, water container carriage, rotary handle and snap close handle and constitute.Hang the sample hook housing and be connected with the up-down main shaft, the up-down main shaft is connected with rotary handle, and the water container carriage is connected with the snap close handle with the up-down main shaft through web member.When the snap close handle places " opening " position, rotate the rotary handle on the main body stand at this moment, only hang the sample hook housing and move up and down; When the snap close handle places " lock " position, rotate the rotary handle on the main body stand at this moment, then hang sample hook housing and water container carriage and do motion up or down synchronously.This instruments design is ingenious, and volume is little, and is easy to operate, can measure the proportion of coarse-grained soil quickly and efficiently.
Adopt good effect of the present invention to be: it has successfully solved permanent, the lasting stressed effect of high precision and large measuring range electronic balance, and the zero point drift that causes influences test data result's accuracy problem, can proofread and correct electronic balance at any time.Therefore, it can obtain test result more accurately.This device integration is good, and simple to operation, quick, reliable.
Description of drawings
Fig. 1 is a structural representation of the present invention
The practical implementation method
Sample put into Metal net basket 3 and hang over hang on the sample hook housing 5, and more than the water surface in water container 2.Water container 2 mid-entry (depth of water is a little more than the height of Metal net basket 3) also are placed on the water container carriage 6, and electronic balance 1 is seated on the main body stand instrument platform 10 of water container 2 bottoms.When snap close handle 8 places " opening " position, rotate the rotary handle 9 on the main body stand 7 at this moment, then only hang sample hook housing 5 and move up and down through up-down main shaft 11; When snap close handle 8 places " lock " position, rotate the rotary handle 9 on the main body stand 7 at this moment, then hang sample hook housing 5 and do motions up or down synchronously through up-down main shaft 11 with water container carriage 6.
When utilizing buoyancy appearance of the present invention that the proportion of coarse-grained soil is tested, at first should this instrument steadily be seated on the instrument platform.Get aliquot part 500～1000g (m then
s).The cleaning down sample does not have dust and other dirts until particle surface.The quality m that claims beaker (water container 2) and water in the cup
1, Metal net basket 3 slowly is immersed in the water, claim beaker 2, water in the cup and the outstanding gross mass of the Metal net basket in water 3 again with not ing, and the temperature of measuring vessel 2 interior water immediately, accurately to 0.5 ℃.Calculate the outstanding not buoyancy quality m of the Metal net basket in water 3
aSample diel under water is taken out, puts people's Metal net basket 3 immediately, slowly be immersed in the water, and in water, rock, when not having bubble and overflow till.The gross mass m that claims beaker 2, water in the cup and outstanding not Metal net basket in water 3 and test specimen
3And the temperature of water in the measuring vessel 2 immediately, accurately to 0.5 ℃.Take out sample drying, weighing.Can calculate the volume of sample particle according to Archimedes's the law of buoyancy,, just can calculate the rate of specific gravity of this coarse-grained soil again by the dry ground quality.
