Description
A kind ofly relate to intelligent soil liquid plastic combine tester, be used for the rational matter test of physics, water of civil engineering soil, belong to the physical detection instrument.
In civil engineering, for satisfying engineering design, construction, the needs of quality control and detection must carry out physics, water reason and chemical property analysis of experiments to the soil of design, working-yard, so that decision is to the choice of soil, and construction technology is handled and quality control.The liquid soil plastic limit is the quality index that soil test must be done, and it provides data for dividing great soil group, calculating natural consistency, plasticity index etc., is to be related to the key of project factor.
The soil body is in different physical states respectively because the water cut difference, i.e. flow state, plastic state, semi-solid state, and the boundary water cut of flow state and plasticity state is native liquid limit, uses W
1Expression.The boundary water cut of plastic state and semi-solid state is the plastic limit of soil, uses W
pExpression.Usually to the measurement of liquid soil plastic limit, be metal cone, under the certain altitude condition with certain mass, metal cone is bored into the soil body with free falling body state, and bore the degree of depth and represent with the h value, and by drawing, table look-up, repeated calculation draws the liquid plastic limit value of soil, plasticity index etc.
In the prior art, generally adopt dish formula instrument, put the liquid plastic limit that awl and rubbing method are determined soil.External at present as states such as U.S., day, the former Soviet Union, many researchs have been done in the measurement of liquid soil plastic limit, measure plastic limit of soil as the former Soviet Union with statocone, Japan has developed a kind of piezoelectric ceramic vibrator sensor in the nineties, and this sensor application is in the mensuration of liquid soil plastic limit.It is several that the liquid plastic combine tester of Shi Yonging mainly contains digital-code type and photo-electric etc. at home.This quasi-instrument can only carry out analytical measurement (promptly can only record awl and go into depth value), and the liquid plastic limit value of soil then needs by just obtaining a result after the loaded down with trivial details work such as artificial drawing, computation of table lookup.The effort of not only taking a lot of work, and the human factor influence is big, can not satisfy the needs of engineering construction high speed development.
In view of this, the purpose of this utility model just be to provide a kind of fast, accurately, high, the measurement result visual clear display of precision, operation is easy to carry, function complete, the liquid soil plastic limit combined measurer of applied range.
The utility model is taked following technical scheme, a large amount of soil tests and summary of experience proof, and the awl of soil body test specimen goes into degree of depth h and there is funtcional relationship in water cut w, that is:
h＝aw
b
In the formula: h goes into the degree of depth for awl;
W is the percentage water cut;
A, b are coefficient.
The formula both sides are taken the logarithm:
lnh＝lna+blnw
So just become monobasic once linear equation, thereby the mensuration of liquid soil plastic limit is gone into the degree of depth and the linear relation of water cut on log log coordinates with regard to the awl that is reduced to surveying instrument.
Based on above-mentioned principle, it is good that the utility model just is to design a response characteristic, and the geometric displacement quantitative change that can accurately awl be gone into degree of depth h becomes electric weight, and water cut is a set-point for this instrument, is finished by other tests.Therefore this instrument only need be measured and bore the degree of depth, the input water cut, and all the other work are then finished by circuit in the instrument and single-chip microcomputer fully.Therefore design a sensitivity and the good sensing transducer of the linearity is a key of the present utility model, this instrument adopts differential converter, and its principle is referring to Fig. 3, and it is made of the iron core that can freely move up and down between a primary coil and two secondary coils.When iron core during at diverse location, can provide corresponding electric signal automatically, equipment circuit and microcomputer are gathered conversion process to this information, fluid plastic limit value.Therefore this instrument is made up of frame, base, measurement mechanism, sample box lifting levelling device, liquid crystal display, function keyboard six parts, by the above-mentioned the purpose of this utility model that realizes, below in conjunction with drawings and Examples in detail, principle of work of the present utility model and architectural feature are described in detail.
