Abstract
The invention provides an experiment device for carbonate rock corrosion speed under a karst-region soil environment, aims to solve the problems that current corrosion experiments under the soil environment can only measure the corrosion test piece weight loss, detection data is single, and sufficient data support cannot be provided for corrosion researches, and belongs to the field of corrosion researches. The experiment device comprises a tank with an upper-end opening, a water guide pipeline and an air guide pipeline, wherein a draining hole is formed in the bottom of the tank, fiber cloth or a multilayer screen is laid at the upper-end opening of the tank, a water receiving tank is arranged at the bottom of the tank, one end of the water guide pipeline is communicated with the bottom of the water receiving tank, and one end of the air guide pipeline is communicated with the tank lateral wall above the water receiving tank.
Description
Technical field
The present invention relates to a kind of erosion rate experimental provision, belong to soil corrosion research field.
Background technology
Corrosion test piece method is one of method of quantitative evaluation karstification and carbon remittance intensity thereof, that the test piece of unification production standard carbonatite is positioned in the air, soil surface and soil different depth, certain hour (being generally a water year) takes out afterwards and weighs, indirectly calculate that the karst carbon remittance intensity of putting place is buried in test piece according to test piece reduction, the method is widely used in karst carbon and converges in research, but at present flag is only put in earth's surface or is imbedded in soil different depth by the corrosion experiment under soil environment, final measurement is single corrosion test piece these data weightless, lack collection and the research of related data under soil environment.
Summary of the invention
The object of the invention is to: a kind of karst soil environment erosion rate experimental provision is provided, to solve at present for the corrosion experiment under soil environment, only can record corrosion test piece these data weightless, without detecting, data are too single, cannot provide the problem of enough Data support for corrosion research.
For solving the problem, intend adopting so a kind of karst soil environment erosion rate experimental provision, comprise the cell body of upper end open, conduit pipe and bleed pipeline, the bottom of cell body offers leaking hole, cell body upper end open place is equipped with fiber cloth or multilayer gauze, the bottom of cell body is provided with water receiving tank, and one end of conduit pipe is communicated with the bottom of water receiving tank, and one end of bleed pipeline is connected with the cell body sidewall above water receiving tank.
As preferred structure further, the other end other end of conduit pipe and bleed pipeline being respectively arranged with valve or conduit pipe and bleed pipeline is respectively arranged with detachable stopper, during use, take off stopper, be passed into the top of water receiving tank in cell body and water receiving tank respectively through conduit pipe and bleed pipeline with flexible pipe, use syringe from the holard in flexible pipe extraction cell body and soil air respectively, so that follow-up study.
For saving material, described water receiving tank and cell body are integral type structure;
For ease of the collection of the holard, the upper end open of cell body is the funnel-shaped structure of indent, and the upper end notch correspondence of described water receiving tank is arranged at immediately below the upper end open of cell body;
Also woven wire is provided with, for laying carbonatite test piece on woven wire directly over cell body;
For ease of adjusting the buried depth of woven wire, the upper end of cell body is also provided with montant, and montant is marked with scale mark, and montant is adjustable height structure;
In each carbonatite test piece, equal correspondence is fixed with lifting rope, during use, the upper end of lifting rope extends to above soil layer, be convenient to the taking-up of carbonatite test piece, and take out carbonatite test piece time can not impact other carbonatite test pieces neighbouring, existing carbonatite test piece take out time, owing to cannot accurately locate, embedding scope need may carry out tentative excavation in test piece, obviously can have considerable influence to neighbouring test piece.
Compared with prior art, major advantage is as follows in the present invention:
1, need can not produce too large disturbances when regularly getting flag stage by stage;
2, can sample soil air;
3, can sample the holard;
4, flag depth of burial, distance between flag and holard soil gatherer are controlled.
The holard can be collected while doing corrosion test piece test to be used for measuring water chemistry property, soil air can be collected and be used for measuring air composition in soil, for corrosion research provides multi-faceted Data support, corrosion test piece can be taken out exactly by stages and disturbance not produced to other test pieces, meanwhile, flag depth of burial can be controlled easily.
