Description
Technical field
This utility model relates to civil engineering soil test field, particularly relates to one and reinvents saturated soil water chemistry pour to strain to test device.
Specifically, this device is a kind of for studying the sample preparation device that soil sample mechanical characteristic is affected by water soil chemical field, it is particularly well-suited to have that sample preparation is uniform, initial structure is weak and the water chemistry effect advantage such as substantially, but infiltration coefficient is little, (ensureing initiating structure concordance, distilled water mixes with dry ground to depend merely on the longest mud sample preparation method of diffusion change pore solution composition.
Background technology
At present, along with engineering-built with use during environmental problem become increasingly conspicuous, increasing scholar takes up geotechnical engineering problems produced by various environmental problem.Wherein, the change of mechanical property after the soil body suffers chemical erosion starts to be taken seriously, but how to prepare and can effectively simulate the test soil sample after the soil body suffers chemical erosion and become a key issue.Although undisturbed soil sample can reflect the prototype structure of the soil body more truly, but is affected by restriction and the environment of sampling technique, its result of the test is unsatisfactory, and discreteness is bigger.On the contrary, the test soil sample after chemical erosion is produced in indoor, and not only character is relatively uniform and result of the test discreteness is less；And the condition of sample is controlled, it is simple to specific experimental study.But owing to the soil body is very slow with the course of reaction of chemical solution, the soil sample of several weeks at least, at most several months, especially infiltration coefficient little (sample that mud sample preparation method prepares), the sample preparation cycle is the most longer.Accordingly, it would be desirable to develop a quick preparation device by chemical erosion sample.
Utility model content
The shortcoming and defect existed in view of above-mentioned technology, this utility model aims to provide one and reinvents saturated soil water chemistry pour to strain to test devices and methods therefor, is particularly well-suited to the complicated soil test with sample preparation cycle length of chemical environment.
In order to achieve the above object, the technical solution of the utility model is:
This assay device includes by sample on leaching object and lower sample；
It is provided with head support, liquid-collecting bottle, leaching instrument and rubber catheter；
Upper sample and lower sample are positioned in leaching instrument；
Liquid-collecting bottle and leaching instrument are individually positioned in the upper and lower aspect of head support；
Connected by rubber catheter between liquid-collecting bottle and leaching instrument；
Head support provides different initial water pressure difference to liquid-collecting bottle.
This utility model compared with prior art, has an advantage in that:
1. head support is provided with moveable bearing plate, can adjust head height according to the kind of leaching soil sample, it is to avoid filtrate is to the erosion of soil sample or disturbance；
The saturated soil sample of the most existing preparation different aperture Hydrochemical Composition generally has three kinds of modes: mixing method, infusion method and leaching method；Although mixing method can reach chemical equilibrium quickly, but can not simulate the change in mechanics after natural rock-filled suffers chemical erosion well；Infusion method relies primarily on diffusion and changes soil body pore water chemical composition, but its process is very slow, and the soil sample of several weeks at least, at most several months, especially infiltration coefficient little (sample that mud sample preparation method prepares), the sample preparation cycle is the most longer；Comparatively speaking, leaching method compensate for the deficiency of above two method, achieves comparatively ideal result；
3. the laboratory test soil sample by chemical erosion is prepared, the method directly soaked after the most mostly using evacuation, the method not only needs the long time, and the chemical concentrations being difficult to judge in intrusion soil sample solution and whether reach to balance；Use leaching instrument by forcing the pore solution in displacement soil sample, required chemical concentrations can be arrived rapidly, and displacement can have been judged whether by the concentration measuring filter liquor；
4. this device simple structure, easily operates；And in a leaching instrument can simultaneously two parallel samples of leaching, for existing technology, effectively reduce cost, there is preferable economic and practical.
