Abstract
The present invention adopts hydraulic method in testing expansion pressure of solid expansion material, and the method has intuitive and accurate measurement result and uses simple measurement equipment. The method of the present invention may be used widely in the research of static breaking agent and the research of geologic disaster and environment problem caused by bentone, etc. as well as the expansion pressure test, expansion mechanism research, expansion condition simulation, expansion control research, etc. of solid expansion material. In addition, it provides condition for some chemical reaction research and thermal data measurement under high pressure condition.
Description
The invention belongs to the test of solid material, especially for the test and the device of expansion pressure of soild expansion material.
Expanding materials such as bentonitic clay, CaO, static breaking agent will produce the bigger swelling pressure under certain condition.Utilize its expansion characteristics can broken brittle solid material, as: rock, concrete etc.If it is unfavorable to control, will produce disaster, will produce tunnel, water conservancy projects, road etc. as bentonitic water-swellable and destroy; Therefore, the research for the expansion character of expansion of solids material just seems extremely important.When the expansion character of research expansion of solids material, a most important parameter is the test of the swelling pressure.And the general at present method of testing that adopts is to utilize resistance strain gage to measure; In measuring process, mainly have following problem: the calibration more complicated of foil gauge, be difficult for accurately measuring, reading is directly perceived inadequately, calculate more complicated, the result is inaccurate.Therefore, just need convenient, the visual and accurate swelling pressure measuring method of reading of a kind of measurement.Adopt hydraulic pressure to carry out the turgor pressure force measurement, still do not have report at present.
Purpose of the present invention just provides a kind of method of testing and proving installation of expansion pressure of soild expansion material.
For reaching this purpose, design of the present invention is to utilize the liquid pressed volume to change little, pressure to change characteristics greatly, with tested expansion of solids material with in the closed container of the instrument that the medium of its expansion is packed into be connected to gaging pressure or instrument, full of liquid.When the expansion of solids material expands, its volume will become greatly, and the pressure of liquid is raise; The pressure of measuring its liquid just can draw the swelling pressure of expansion of solids material.So just realized the purpose of invention.
For finishing this inventive concept, the present invention is with tested expansion of solids material and makes the medium of its expansion (as CaO+H
2O) closed container that is connected to tensimeter (or pressure sensor) and filled with fluid is put in the sealing in the rubber-like bag (as elastomer bag) of packing into together then.Along with the variation of time, the expansion of solids material expands under the effect of inflating medium gradually; The liquid that is contained in the closed container is compressed, and pressure raises gradually.Therefore on tensimeter (or pressure sensor), can directly obtain fluid pressure numerical value.The pressure of the swelling pressure of expansion of solids material and its liquid that is full of on every side is in equilibrium state, and the pressure of the liquid that is read on the tensimeter is the swelling pressure of expansion of solids material.Also just a kind of measurement is convenient, the visual and accurate measuring method of reading for the measurement of expansion pressure of soild expansion material provides.
The invention provides a kind of method of testing and proving installation of expansion pressure of soild expansion material.The present invention adopts hydraulic method to carry out the test of expansion pressure of soild expansion material.Intuitive measurement results, accurately, proving installation is simple, easy-to-use, for the test of expansion pressure of soild expansion material provides a kind of new method.The present invention is widely used in the research of static breaking agent, and aspect such as the geologic hazard that is caused by expansions such as bentonitic clays and research on environmental issues; The aspect such as swelling pressure test, mechanism of intumescence research, the test of expansion condition simulation, expansion Control Study that also can be used for the expansion of solids material; The condition that provides is provided for the research and the thermodynamic data of carrying out some chemical reaction under the condition of high voltage.

For the accuracy that improves measurement with add wide-measuring range; Around the expansion of solids material, should be full of the liquid that pressure transmission is used fully, just require to fill with in the closed container liquid; When the swelling pressure of expansion of solids material are higher, require to have in the closed container liquid of certain pressure.The way that addresses these problems is: the connection hydraulic system is come liquid make-up and is pressurizeed to liquid on closed container.
Fig. 1 is the hydraulic schematic diagram of a proving installation, is pressurizeed to closed container (4) liquid make-up with to liquid by hydraulic pump (1).Must guarantee that in the expansion process of expanding material liquid can pressurize to closed container (4), can not flow backwards to hydraulic pump (1), just need be connected to retaining valve (2) in the exit of hydraulic pump (1).After the expanding material test finishes, system pressure must be lowered, therefore also should be connected to unloader (6).
