Description
Technical field
The present invention relates to terrace antiseepage formula soil osmotic coefficient investigating device in a kind of Large Oil Tank area fire wall.
Background technology
At present, China's underground water and Soil Environmental Pollution situation are increasingly severe, extensive exploration especially in oil,
After the extensive use of exploitation, refining development and products thereof, caused underground water pollution turns into the problem of very important.With
The continuous improvement of national environmental standard,
The antiseepage practice in tank field ground has 4 kinds:Concrete anti-seepage, HDPE film antiseepage, sodium-based bentonite waterproof carpet impervious barrier and
Clay core.4 kinds of practices can be carried out in theory, be that construction is simple, cost are relatively low the characteristics of concrete anti-seepage, but it is by material
Material control, construction quality are had a great influence, and construction quality is difficult to control, and durability is relatively poor, are most importantly easily occurred
Crack, the appearance in crack make whole seepage control measure fail;The current case history of HDPE film antiseepage is more, and effect is preferable, and quality is suitable
Control, durability is preferable, but its cost is more expensive, it is difficult to be widely applied.The practice of sodium-based bentonite waterproof carpet antiseepage does not have at present
There is case history, its construction costs, implementation result are not grasped also;Clay core requires the anti-of clay in tank field ground region
It is 1 × 10-7cm/m to ooze performance to reach thickness 1.5m infiltration coefficient.1.5m thickness is very tired for enterprise's site operation
Difficult, therefore we improve to original ground surface soil, improved formula soil is laid 0.5m with regard to that can meet tank field ground
The requirement of antiseepage, by reducing the infiltration coefficient of formula soil, the barrier performance of formula soil is improved, to reduce the requirement of thickness, made
Oil depot scene can be implemented.Clay has self-reparing capability, is a kind of cheap impervious material, it is preferable to consider
Impervious material.
Make impervious material using clay and modified clay, test and mining site construction in most critical be exactly be antiseepage
The measure of material (clay and modified clay) infiltration coefficient, needs in civil construction industry to the measuring method of soil permeability coefficient
Time it is very long, not determine the relatively large soil of infiltration coefficient, the time determined for the relatively low clay of infiltration coefficient
It is longer, it is unfavorable for carrying out experimental study, and the precision measured is nor very high.
The content of the invention
Present invention is primarily intended to for above-mentioned situation, there is provided a kind of dress of energy Fast And Accurate Determination clay pervasion coefficient
Put.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals:Prevent in Large Oil Tank area
Terrace antiseepage formula soil osmotic coefficient investigating device in fiery dike, it includes:
Displacement pump;
Piston container, including water, oily piston container, lower end are connected with the displacement pump;
Fill out sand tube, its arrival end connect the output end of piston container, port of export connection test tube;
Two secondary stress sensors, the port of export of fill out sand tube and the pressure of arrival end are determined respectively;
And Data Detection and processing system.
Pass through above-mentioned technical proposal, the present invention can quickly, accurately determine clay pervasion coefficient, and the time of measure is less,
And there is higher precision.

Accompanying drawing 1 is a kind of structural representation of the present invention.
Wherein:1st, displacement pump;2nd, piston container;3rd, pressure sensor;4th, fill out sand tube;5th, insulating box;6th, test tube;7th, calculate
Machine system.
Embodiment
Below by embodiment, and with reference to accompanying drawing, technical scheme is described in further detail.
Embodiment:Terrace antiseepage formula soil osmotic coefficient investigating device in Large Oil Tank area of the present invention fire wall, such as
Shown in accompanying drawing 1, it includes:
Displacement pump 1;
Piston container 2, including water, oily piston container, lower end are connected with the displacement pump 1;
Fill out sand tube 4, the output end of its arrival end connection piston container 2, port of export connection test tube 5;
Two secondary stress sensors 3, the port of export of fill out sand tube and the pressure of arrival end are determined respectively;
And Data Detection and processing system.
Piston container 2 and fill out sand tube 4 are placed in insulating box 5.
The inner chamber of fill out sand tube 4 is handled using frosted, inwall is formed matte surface, is smeared in experiment on matte surface
Vaseline.
For ease of understanding the general principle of the present invention, it is further illustrated as follows:Such as Fig. 1 measure clay pervasion coefficient dresses
Put structural representation, the core component in structure is fill out sand tube, and the fill out sand tube in device uses 316 type stainless steels, core diameter
25mm, rock core length range are 25~35mm, and highest pressure-bearing 50MPa, the inner chamber of fill out sand tube forms inwall using frosted processing
Matte surface, vaseline is smeared on matte surface in experiment, can so prevent that liquid is on tube wall in flow event
Channelling.Displacement pump uses ISCO pumps, the twin-tubs of ISCO pumps can continuous driving replace, injection rate scope be 0.001ml/min~
10ml/min, 0~50MPa of injection pressure limit.Water, oily piston container lower end are all connected with displacement pump, upper end all with fill out sand tube
Arrival end be connected, so realize that water, oil are implanted sequentially by the regulation of valve.The port of export of fill out sand tube connects pressure with arrival end
Force snesor, determines the pressure at both ends, and the liquid of port of export outflow carries out metered volume by test tube.
Experimental method and step:
Experimental basis Darcy's law, pass through the speed for determining the pressure difference at permeable matrices both ends, fluid permeability passes through impervious material
Degree, the permeability coefficient of impervious material is calculated according to Darcy formula.
Experimentation is first to smear vaseline in the inwall of fill out sand tube, and the compacting of 30cm sands is then inserted in fill out sand tube,
The lid of entrance is covered, displacement is carried out using displacement pump, transfer drive is level pressure displacement for the displacement of pump, pressure 20MPa, and displacement is steady
After fixed, speed that record port of export fluid goes out, by Darcy formula, the infiltration coefficient of unit length sand is calculated.Then take
Go out sand drying fill out sand tube.
10cm sands are inserted in the fill out sand tube port of export again, prevent mud from being discharged under high pressure along pipe.Then, treated
Ground surface soil dry powder, is fitted into fill out sand tube, often loads 5cm depths, is compacted using hydraulic press, the pressure parameter of hydraulic press is set as
1KN, load successively, until fill out sand tube is filled.Then fill out sand tube is connected on driving device, driven successively with water and diesel oil
Replace.
In whole experiment process, accumulative time of penetration, accumulative infiltration capacity, injection end pressure and other parameters have been carried out in real time
Monitoring.After displacement terminates, the impervious material in fill out sand tube is changed, changes compacting condition, then carry out displacement.
When calculating clay pervasion coefficient, pressure difference caused by port of export 10cm sands is subtracted.
Experimental program and result:
Specific experiment scheme and experimental results are shown in Table 1.
The experimental program of table 1 and experimental results
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
