Technical field
The utility model is related to soil test fields, and in particular to a kind of infiltration device for soil sample test.
Background technology
Prepare a kind of important means that the uniform manipulated soil of sample is the physico-mechanical properties experiment for conducting a research native.But specially
Door is carried out at the same time the research for preparing manipulated soil for pressurization of bearing a heavy burden with infiltration not yet to be occurred.Meanwhile how to ensure that water uniformly infiltrates
The a great problem for always perplexing experimenter, causes test error larger or even test failure.
Invention content
In order to overcome the defect of the above-mentioned prior art, the purpose of this utility model is to provide one kind to try for the preparation of soil sample
The infiltration device tested can realize the process to seep water to the model soil body under heavy burden pressurized conditions；It is equal that the arrangement achieves water simultaneously
In the even infiltration soil body；To ensure that the uniformity for preparing sample；Due to preparing soil sample using persistent pressure one-pass molding
Method avoids the error that complicated stress environment carrys out test tape.
In order to achieve the above object, the technical solution of the utility model is realized in：One kind is tried for the preparation of soil sample
The infiltration device tested, including be arranged from top to bottom pressure-bearing panel, support plate, upper layer infiltration orifice plate and lower layer infiltration four layers of orifice plate
Structure, the pressure-bearing panel are surrounded by inlet opening, and the support plate is hollow, is equipped on the supporting plate corresponding with pressure-bearing panel
Inlet opening, upper layer infiltration orifice plate is equipped with inlet opening corresponding with pressure-bearing panel and support plate, the upper layer water seepage hole
Plate is equipped with drainage channel anyhow staggeredly, and upper layer osculum, lower layer's infiltration orifice plate are equipped in drainage channel intersection
It is equipped with lower layer corresponding with upper layer osculum osculum.
It is additionally provided with the cushion cap for being used to support top pressure-bearing panel in the middle part of the upper layer infiltration orifice plate.
The cushion cap is five or more.

The drainage channel is 12 or more.
The pressure-bearing panel, support plate, upper layer infiltration orifice plate and lower layer's infiltration orifice plate corner location respectively lay two pin holes,
Whole device is locked by pin and screw.
The utility model is due to the use of four-layer structure and includes support plate, the mistake that can be seeped water under heavy burden pressurized conditions
Journey, avoids influence of the loading and unloading to model resistance to shear of soil path, and thicker poly (methyl methacrylate) plate can bear overlying load completely
Weight, make side pressure marginal not water make remoulded sample process be achieved, have it is solid and reliable, durable, water filling facilitates fast
The advantages of victory quickly improves experiment progress and working efficiency, significantly reduces labor intensity.
Due to the use of cushion cap, the characteristics of being seeped water under heavy burden pressurized conditions is reached, has avoided loading and unloading
Influence to model resistance to shear of soil path.
It due to the use of multiple inlet openings, upper layer osculum, drainage channel and lower layer's osculum, and is uniformly distributed, ensure that
Water uniformly enters the uniformity for being seeped into soil sample and making molding soil sample.
