Abstract
The utility model relates to a soil research device, in particular to an undisturbed soil leaching simulation device which is used in a laboratory. The utility model aims to provide a device which simulates the soil leaching phenomenon on the premise of not changing the soil structure. The device comprises a leaching column and a collection controller which are connected with each other through threads, wherein a perforated plate is arranged at the connection part of the leaching column and the collection controller. The device further comprises a handle and a soil cutting device, wherein the handle is positioned at the top end of the leaching column, and the soil cutting device is positioned at the bottom of the leaching column and is connected with the leaching column through threads. Diversion ports are formed in the leaching column. A vent is formed in the handle. The undisturbed soil leaching simulation device leaches the undisturbed soil without changing the soil structure, has small error, and obtains the conclusion which is closer to the reality.
Description
Technical field
The utility model relates to the soil investigation device, a kind of specifically undisturbed soil eluviation simulator that in the laboratory, uses.
Background technology
Materials such as the salt in the topsoil, nitrogen phosphorus and heavy metal, agricultural chemicals can enter into the soil bottom through eluviation; Underground water is caused potential threat; Therefore; Carry out the leaching rule research of all kinds of materials in soil, can verify the migration velocity of these materials in soil and reach phreatic pollution risk.Because field test is difficult to collecting leaching liquor; Carry out indoor with the mode of leaching post so the leaching test is many; Generally be after fetching earth in the field; In the leaching post, load and carry out lab simulation, but this method has changed soil texture, the conclusion that obtains is difficult to describe the actual leaching state of field soil.
Summary of the invention
The purpose of the utility model is, provides a kind of under the prerequisite that does not change soil texture, the device of simulated soil leaching phenomenon.
A kind of undisturbed soil eluviation simulator comprises leaching post and collection controller, and to be threaded, the junction is provided with punched-plate between said leaching post and the collection controller.
This device also comprises handle and soil-cutter, and said soil-cutter is positioned at the leaching column bottom, with between the leaching post to be threaded, said handle is positioned at leaching capital end.
Said leaching post is provided with flow-guiding mouth.
Said handle is provided with air hole.
The leaching post of the utility model is that undisturbed soil is carried out leaching, does not change soil texture, and error is little, and the conclusion and the reality that obtain are more approaching.
Description of drawings
Fig. 1 is the structural representation of the utility model drawing out soil equipment;
Fig. 2 is the utility model eluviation simulator structural representation.
Embodiment
Embodiment one
A kind of undisturbed soil eluviation simulator, this device comprise leaching post 2 and collection controller 4, and to be threaded, the junction is provided with punched-plate 5 between leaching post 2 and the collection controller 4.
This device also comprises handle 1 and soil-cutter 3, and said soil-cutter 3 is positioned at leaching post 2 bottoms, with between the leaching post 2 to be threaded, handle 1 is positioned at leaching post 2 tops.
Said leaching post 2 is provided with flow-guiding mouth.
Said handle 1 is provided with air hole.
Embodiment two
A kind of undisturbed soil eluviation simulator, this device comprise handle 1, leaching post 2, soil-cutter 3 and collection controller 4, and handle 1 is positioned at leaching post 2 tops; During use; Handle 1 is directly covered on leaching post 2 tops, and handle 1 is provided with air hole, can reduce the pressure that fetches earth; Simultaneously can balance leaching post 2 inside and outside atmospheric pressure, keep in the post soil indeformable.
Leaching post 2 is by several length differences but internal diameter constitutes with all identical pipe of pipe thickness; Round tube inside diameter 150mm, thickness of pipe is at least 7mm, is processed by stainless steel material; In use; According to the leaching degree of depth require confirm use by one still two or more pipes make up use jointly, when two or more pipes make up when using jointly, the junction connects with engage thread between each pipe.
Soil-cutter 3 is positioned at leaching post 2 bottoms, with between the leaching post 2 to be threaded.Use when this covering device fetches earth in the field, the lower end of soil-cutter 3 (end fetches earth) is for being similar to the structure of circular arc thin-walled blade, and be concrete, and the wall thickness of the end that fetches earth is 1/10～1/12 of a upper end wall thickness.When fetching earth, choose the position of fetching earth after, soil-cutter 3 is aimed at the position that will fetch earth; Vertical direction presses down (also available hammer is auxiliary) handle 1; Soil-cutter 3 and leaching post 2 common entering in the soil are fetched earth,, stop to press down when soil surface during apart from leaching post 2 upper end 100mm; The soil of getting has so farthest kept original state, and soil layer construction is not destroyed.
