Description
Technical field
The present invention relates to a kind of testing laboratory leaching analogy method, particularly a kind of indoor multilevel simulated eluviation test method.
Background technology
Along with the develop rapidly of China's industry, air, underground water, soil etc. pollute also all in continuous aggravation, and for the sustainable development protecting ecologic environment and economy is opened, these pollutions are also taken seriously gradually on the impact that soil, buildings etc. cause.Such as in the impact on all kinds of soil body such as laboratory simulation acid rain, agricultural chemicals, to the vertical migration situation of element various in the soil body.In actual tests, need to bury pipe underground to collect leaching water in the test soil body, pilot region soil body surrounding is also needed to surround, though such test can reflect the actual conditions of the soil body, but test soil disturbance large, leaching liquor also can pollute the bottom soil body, and experimental study process is too tediously long, workload is large, needs to drop into a large amount of manpower and materials.
Mostly existing indoor leaching test is traditional native fish method, but this method is large to soil disturbance, easy formation is circulated to the local of the soil body, and the long-time test soil body easily causes a large amount of loss, and existing apparatus can't measure the depth of interaction of leaching to the soil body.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, there is provided one can load undisturbed soil sample, prevent and treat soil sample and run off, measure the eluviation degree of depth, the further analytical test of leaching liquor and recovery, the more uniform indoor multilevel simulated eluviation test method of leaching, and equipment therefor is little to sample disturbance, structure is simple, easy to use.
Concrete steps are:
(1) set up an a kind of indoor multilevel simulated eluviation test unit, comprise leaching liquor reservoir, soil body container and leaching solution collector.
Leaching liquor reservoir is placed in above soil body container, and leaching liquor reservoir side is provided with rule, is provided with pin hole bottom leaching liquor reservoir bottom leaching liquor reservoir, is connected below leaching liquor reservoir with soil body container; Soil body container is placed in the middle of leaching liquor reservoir and leaching solution collector, and soil body container bottom is provided with soil body container bottom hole, places permeable stone above soil body container bottom hole, and soil body upper vessel portion and leaching liquor reservoir junction are placed with pin hole pad; The connection with leaching solution collector is provided with around soil body lower vessel portion; Device can arrange one or more soil body container according to test demand between leaching liquor reservoir and leaching solution collector; Leaching solution collector is arranged at device bottom, and leaching solution collector top periphery is provided with the connection with soil body container, and bottom sides is provided with valve.
Described leaching liquor reservoir, pin hole pad, permeable stone, soil body container, leaching solution collector, the size of getting undisturbed soil according to existing rig makes different specification size, for adapting to different tests requirement.
(2) when simulated eluviation is tested, permeable stone is put into soil body container bottom, and the undisturbed soil sample fetched or remoulded sample are placed on permeable stone, and pin hole pad covers on soil body container, soil body container body is placed on leaching solution collector, puts leaching liquor reservoir above soil body container.In leaching liquor reservoir, inject quantitative leaching liquor, leaching liquor flows into soil body sample by pin hole pad, finally flows into leaching solution collector.The leaching liquor collected reclaims by valve, for further analysis of experiments.
Advantage of the present invention and beneficial effect are:
(1) arrange multistage soil body container, the leaching for the different depth soil body is tested, and analyzes the soil body not at the same level and drenches fluid composition and test further.
(2) drench fluid according to soil body container height and the soil body not at the same level, test leaching is to the influence depth of soil sample.
(3) soil body container bottom can prevent and treat soil body loss after placing permeable stone.
(4) be provided with pin hole bottom leaching liquor reservoir, above soil body container, place pin hole pad, the even leaching of leaching liquor can be made like this to soil body surface, avoid spraying inequality, avoid the formation of local circulation.
(5) get undisturbed soil sample selection of dimension different size according to rig, the original state soil body obtained directly can be put in soil body container and do leaching test, reduces the disturbance to the soil body.
