Description
Technical field
The utility model relates to a kind of eluviation simulator, particularly a kind of unsaturation soil body leaching and Simulation of Seepage Field device.
Background technology
The physico-mechanical properties of the soil body depends primarily on its mineralogical composition, chemical composition and architectural feature etc.Its essential mineral composition is smalite, illite and chlorite etc.Red clay for example, its clay mineral grain is superfine.Between the clay mineral often with static(al) to attraction,---face, limit---mode of face combination that is face forms crumb structure, the fine pore in granule is often filled by planar water.Clay mineral has stable crystallization screen work, and the particulate group is formed firm crumb structure, and this " unity " acts on, and has improved the intensity of the soil body.The free oxide that content is few is very large on the mechanical property impact of red clay.Water chemistry effect between the red clay soil body and the water (ion-exchange, redox etc.) is mineralogical composition, the cementing matter of the dissolving soil body or makes some composition crystalline deposit, cause the micromechanisms such as native porosity, soil particle arrangement mode to change, change the soil property proterties, the reason that the natural intensity of the soil body and deformation characteristic are changed.But under the infiltration condition because the passage of free iron oxide so that cementation weaken, obvious on the impact of the engineering properties of red clay.Seepage flow has dissolution to the free oxide in the red clay, and then destroys cementing between former granule, affects the physico-mechanical properties of red clay.
In order to study various element vertical migrations in the foundation soil body, need to according to test purpose in ground pipe laying to collect leaching water, thereby also to adopt water-stop curtain to prevent that with surrounding around the pilot region soil body side direction runs off, though such test can reflect the actual conditions of ground or roadbed, but research process is too tediously long, workload is large, needs to drop into a large amount of manpower and materials.Therefore, hope can be at the indoor analogue means of setting up foundation soil body leaching state, to overcome the defective of site test.But this just has higher requirement to soil body eluviation simulator, and existing leaching device is when leaching, because of caliber meticulous, the reasons such as the leaching amount is larger, easily cause subgrade soil top layer ponding to cause seepage pressure excessive, and be difficult to therefrom take out the soil sample that need to carry out mechanical test, therefore can not satisfy the needs of designed test.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of heavy caliber,, sample little to the sample disturbance are prepared into that power is high, simple in structure, easy to use, environmental protection and energy saving and obtain data more accurately unsaturation soil body leaching and Simulation of Seepage Field device.
The utility model is achieved in that a kind of unsaturation soil body leaching and Simulation of Seepage Field device comprise leaching liquor storer, leaching device, soil body leaching simulator and end collection.Wherein the leaching liquor memory device is in the side surface direction that is higher than the leaching device, and leaching liquor storer bottom is connected to the leaching device by the leaching liquor conduit with flowrate control valve; Leaching device and soil body leaching simulator are isodiametric cylindrical structural, and the leaching device is set up on the soil body leaching simulator; End collection places under the soil body leaching simulator, drenches fluid to collect.
Described leaching device comprises motor, annular aproll and rainfall simulator, and motor drives rainfall simulator by rotating shaft and rotates, and rainfall simulator is the circular sheet that is covered with aperture, rainfall simulator outside configuration leakproof rubber ring.
Described soil body leaching simulator is two hollow cylinders that semi-circular arch is spliced, and is tightened up and fills marine glue in case leak-stopping water by physical construction; But every semi-circular arch side arranges vertically equidistant closed side osculum; Tu Kou is put at soil body leaching simulator top, in order to add in due course the soil body or to observe the leaching liquor situation; Soil body leaching simulator bottom arranges the soil body penetration base for supporting, adopts with the disk of uniform hole and tests the soil body to support.
Collection of the described end adopts cylinder design, is connected with soil body simulator bottom by screw socket.
The beneficial effects of the utility model are:
(1) for the situation of traditional soil body leaching instrument small-bore simulated eluviation soil body and consider the required size of supporting mechanical test sampling and the scale effect of structure of carrying out, the utility model adopts the cylindrical earth pillar eluviation simulator of heavy caliber, to obtain more soil sample and test figure in the test each time.
(2) adopt the utility model leaching to obtain sample, substantially without impact, can effectively reduce the disturbance to sample on soil sample, be prepared into power high, thus can avoid open-air direct leaching take a sample adopt machine drilling and affect quality of soil sample.
(3) the utility model is simple in structure, is easy to safeguard, leaching solution and the experiment soil body can be easily changed in modular design, can satisfy the requirement of revision test.
(4) the utility model is easy to use, environmental protection and energy saving, owing to adopting double-disk hollow cylinder mechanism, for completed soil body test, only need open annular fastening device, take out and change the soil body in the soil body leaching simulator, easy to use, and instrument except motor adopts powered battery without other energy consumptions, environmental protection and energy saving.
(5) data are more accurate, adopt closed side osculum and end liquor collecting device to make things convenient for leaching liquor to the different layers position soil body to drench the pH value and constituent content is tested, and can simulate unsaturated soil seepage field situation, thereby obtain more accurate and comprehensive data.
