The accompanying drawing explanation
Fig. 1 is theory diagram of the present invention.
Embodiment
As shown in Figure 1, the invention discloses the migrate system of mode of a kind of ACTIVE CONTROL water in porous medium, comprise water transport moving device 1, measurement mechanism 2, pressure gradient control device 3, described water transport moving device 1 is provided with the permeable section that poromerics is made, and described water transport moving device 1 is connected with described measurement mechanism 2 sealings; Described pressure gradient control device 3 is connected with described measurement mechanism 2 sealings, described pressure gradient control device 3 applies vacuum in various degree to described measurement mechanism 2, thereby make the inside and outside pressure gradient that produces of water transport moving device 1, described measurement mechanism 2 is for measuring the water body migration quantity.
System of the present invention can realize the controllable pressure gradient.
Described measurement mechanism 2 comprises electronic balance, by described electronic balance, measures the water body migration quantity.
Described pressure gradient control device 3 comprises that described instrument applies vacuum in various degree to described measurement mechanism 2 for controlling the instrument of vacuum tightness.
Described poromerics comprises permeable fiber or microwell plate, its objective is the tension effect that utilizes water itself to exist, and the air pressure that saturated poromerics can maintain is relevant with the maximum diameter of hole of poromerics itself with hydraulic pressure maximum pressure differential (being air-entry value).Be that aperture is less, the air-entry value of poromerics itself is higher, otherwise as the same.
The hollow tubular that described water transport moving device 1 is an end sealing, its purpose is that hollow tubular exists the area of pressure gradient larger, thereby can make the migration velocity of Water in Porous Medium accelerate.
The air-entry value of described poromerics is not less than pressure gradient, and this is owing to when pressure gradient, being greater than the poromerics air-entry value, and water transport moving device 1 can be lost maintain the function of pressure differential, and then makes pressure gradient uncontrollable.
While by measurement mechanism 2, measuring the water body migration quantity, described water transport moving device 1 and described pressure gradient control device 3 are fixed; Its objective is in order to eliminate the pipeline fluctuation caused in operating process and affect measurement result.
Before system is used, the poromerics in water transport moving device 1 is carried out fully saturated, and will water transport moving device 1 with measurement mechanism 2 junctions in be full of air free water fully; Its purpose is, whole system is operated under continuous water environment, and then the controlled pressure gradient.
This system not only can be used in experimental study but also can be used in the reinforcing and seepage control project of actual Geotechnical Engineering.
This system can be used in geotechnical centrifuge test, and then the simulating plant transpiration etc.
The invention discloses the migrate system of mode of a kind of ACTIVE CONTROL water in porous medium, relate in particular to the migratory direction of directed change soil water, and can conscious change inside soil body hydraulic performance.Native system has the function that changes soil body water cut and then change the soil mass water force characteristic, and simultaneously, this system can be measured the migration quantity of Water in Porous Medium.Water transport moving device 1 provides a passage that water is migrated out from porous medium for whole system, utilize pressure gradient control device 3 by the hydraulic pressure control in the pore water pressure in porous medium and measurement mechanism 2 under the certain pressure gradient, thereby the water in porous medium is migrated to measurement mechanism 2 under the pressure gradient effect, by measuring the migration quantity that can obtain water outlet.The present invention proposes a kind of system of migration that can the ACTIVE CONTROL Water in Porous Medium, and then change the mechanical characteristics of uncosolidated porous medium.Simultaneously, measure the migration quantity of water outlet.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
