Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing and have
The utility model is described in further detail for body embodiment.
As shown in Figure 1, a kind of laboratory testing rig suitable for the latent erosion characteristic research of soil, which is characterized in that the dress
Setting includes: middle part sleeve；The middle part sleeve inner is provided with cutting ring；Permeable pond is provided at the top of the middle part sleeve；Institute
The bottom for stating middle part sleeve is once provided with small sieve and big sieve from top to bottom；A water inlet pipe is connected on the permeable pond
Road；The middle part sleeve is fixed by fixed device；The middle part sleeve is arranged with a receiving container；The receiving
The bottom end of container is provided with electronic scale.
Further, the fixed device includes: upper cover and lower cover；The upper cover and lower cover are respectively arranged at middle part sleeve
Above and below, it is fixed by hold-doun nut and standing screw.
Further, sealing washer is provided at four angles of the middle part sleeve.
For upper cover, sealing washer is put into upper cover, then permeable stone is put into, places into sealing washer；Wherein sealing
Washer be in order to prevent water flow on the inside of permeable stone and upper cover between it is through-flow, sealing washer be in order to prevent water flow from middle part sleeve
It is through-flow between upper cover inside, also prevent water flow through-flow between cutting ring and middle part sleeve.
For sample, experiment soil sample is fitted into cutting ring, the cutting ring for being then loaded into soil sample is inserted in the sleeve of middle part, in soil
Put a filter paper in sample top；Middle part sleeve is to bear the active force of the banding from upper and lower covers, filter paper can to fix test specimen
So that the water for seeping permeable stone uniformly penetrates into soil sample.
For lower cover, first big sieve is packed into, then small sieve is packed into, is finally put into sealing washer；Wherein big sieve
It is to bear the vertical active force from soil sample, small sieve is then that soil particle progress physics is latent to be lost in order to allow water energy enough to take away,
And be unlikely to directly to form erosion, sealing washer 8 is primarily to allow between middle part sleeve and lower cover as flexible contact, Ke Yigeng
Middle part sleeve 11 is allowed to bear the active force of upper and lower covers banding well.
Middle part sleeve is inserted in upper cover, then lower cover is inserted in, standing screw is packed into, tightens hold-doun nut.
It is disposed vertically, is passed through in water inlet line and determines head or constant-pressure water, water penetrates into permeable stone, penetrates into soil through filter paper
Sample, after permeating soil sample, solution can penetrate into receiving container, electronic scale can moment recording solution variation, take same time
Then solution in interval, precipitating, draw solution are dried, obtaining dry ground particle is the latent erosion particle of physics；Receiving container is can
With the aluminium box dried, the quality of solution and the quality of soil particle can be obtained after drying respectively.
Quality analysis is carried out to the soil particle after drying, can show that latent erosion characteristic changes with time rule, carries out it
Granularmetric analysis can obtain the characteristics of objects of latent erosion.Quality analysis is carried out to the solution of receiving, can obtain the Penetration Signature of soil sample,
Chemical ion analysis is carried out to it, can obtain corrosion characteristics.
Above are merely preferred embodiments of the utility model, it is noted that above-mentioned preferred embodiment should not regard
For limitations of the present invention, the protection scope of the utility model should be defined by the scope defined by the claims..For
For those skilled in the art, without departing from the spirit and scope of the utility model, it can also make several
Improvements and modifications, these improvements and modifications also should be regarded as the protection scope of the utility model.
