Description
Technical field
The utility model relates to a kind of permeance property proving installation, especially a kind of Thawing soil permeance property proving installation.
Background technology
Freezing process is one of conventional method of the engineerings such as mine sinking shaft, subway work.Along with the widespread use of freezing process, its engineering problem brought also is on the increase, as namely there is the excessive deformation such as the borehole wall or tunnel-liner and even break accident after freezing wall thaws.Chinese scholars finds to thaw freezing wall by research, and to cause physical-mechanical property of frozen soil to change be the key factor causing engineering accident, and after freezing wall thaw collapse and freeze thawing, the change of the physical property such as soil body permeability is the content needing emphasis to assess in Geotechnical Engineering construction.
At present, soil body permeability test unit in centrifugal modeling can only test the infiltration coefficient of normal temperature soil, and the permeability test of one dimension can only be done, the endure cold simulation test device that melts circulating effect of soil body penetration performance is still belonged to blank, especially the proving installation about Thawing soil two dimension infiltration coefficient does not also have precedent, therefore provides a kind of Thawing soil permeance property proving installation just necessary.
Utility model content
The infiltration coefficient of normal temperature soil can only be tested in order to overcome current soil body permeability test unit, and the problem of the permeability test of one dimension can only be done, the utility model provides a kind of Thawing soil permeance property proving installation, this Thawing soil permeance property proving installation can not only do the two-dimentional varying head test of Thawing soil, the constant head test of the larger soil sample of infiltration coefficient can also be used for, for the permeance property of the Thawing soil of test various soils, different directions, different freezing modes, different thawing patterns, all can high-level efficiency complete.
The utility model solves the technical scheme that its technical matters adopts: this Thawing soil permeance property proving installation comprises: infiltration water bottle, side drainpipe, soil sample case, upper drainpipe, filtering layer, side water inlet pipe, refrigerating fulid coil pipe, lower drainpipe; This Thawing soil permeance property proving installation has the soil sample case of a square body, the top and bottom of soil sample case are connected to drainpipe and lower drainpipe, refrigerating fulid coil pipe is provided with below soil sample case, for soil sample freeze low-temperature receiver is provided, also can load the liquid of different temperatures in this refrigerating fulid coil pipe, make frozen soil realize thawing of different mode; The surrounding of soil sample case is provided with filtering layer, and the soil sample case at filtering layer place has multiple filter opening, the filtering layer of both sides is respectively equipped with side drainpipe and side water inlet pipe, and the turnover exit of lower drainpipe and side drainpipe is provided with an infiltration water bottle.
Be equipped with in described soil sample case and need water permeation and carry out the earth sample that detects, in filtering layer, blinding is housed.
The junction of described upper drainpipe, lower drainpipe, side drainpipe, side water inlet pipe and soil sample case or filtering layer is equipped with valve.
The beneficial effects of the utility model are: this Thawing soil permeance property proving installation can not only do the two-dimentional varying head test of Thawing soil, the constant head test of the larger soil sample of infiltration coefficient can also be used for, for the permeance property of the Thawing soil of test various soils, different directions, different freezing modes, different thawing patterns, all high-level efficiency can complete, realize the infiltration coefficient test that ice melts soil two dimension.Its soil sample case adopts transparent acrylic board to make, and process of osmosis is directly perceived.
