土壤渗透仪是**检测仪器,用于测定粘质土在变水头下渗透试验。

The soil permeameter is a professional testing instrument for determining the penetration test of clayey soil under variable head.


土壤渗透仪结构性能:

该仪器与WS--55渗透仪原理用途完全相同,在压紧方式上改成中间螺旋杆旋压,并对同类型仪器不足之处做了适当改进,操作使用更为简便。

Soil permeation instrument structural performance:

The instrument is completely identical to the principle of the WS--55 permeator. It is changed to the intermediate screw in the compression mode, and the deficiencies of the same type of instrument are properly improved, and the operation is more convenient.


土壤渗透仪规格:

★试样尺寸:φ61.8mm高40mm(30平方厘米)

★仪器外形尺寸:φ118(管咀除外)高度约155mm,仪器净重约3.5kg。

Soil Permeability Meter Specifications:

★ Sample size: φ61.8mm high 40mm (30 square centimeters)

★ Instrument dimensions: φ118 (except nozzle) height is about 155mm, the instrument net weight is about 3.5kg.


土壤渗透仪操作步骤:

★参照水电部土工试验规程SD128-012-84,制备样,或参照JTJ051--93《公路土工试验规程》T013-93

★把渗水石,密封圈放入底座中,将套筒内壁涂一层凡士林,放入土样环刀,刮净多余凡士林置于底座上。

★放上密封圈,透水石,上盖,旋紧螺杆,不得漏水漏气。

★把进水管口与供水装置联通,并通水排气放平仪器,

★在不大于200cm水头作用下,静置某一时间,待出水管口有水逸出后即可开始测定。

★试验时,将水头管冲水至需要高度后关管夹开动秒表,同时测记起始水头h1,经过时间t后,再测记终止,同是测记试验时与终止时的水温,

★按式计算(变水头)渗透系数;

KT=2.3log

式中:a----变水头管截面积,平方厘米

L----渗径,等于试样高度。厘米

h1----开始时水头,厘米

h2-----终止时水头,厘米

Soil permeation instrument operation steps:

★ Refer to the Geotechnical Test Procedure SD128-012-84 of the Ministry of Water and Electricity, prepare the sample, or refer to JTJ051--93 "Technical Regulations for Highway Geotechnical Engineering" T013-93

★ Put the seepage stone and sealing ring into the base, apply a layer of Vaseline on the inner wall of the sleeve, put the soil sample ring knife, and scrape the extra Vaseline on the base.

★ Put on the sealing ring, permeable stone, upper cover, tighten the screw, and do not leak water and leak.

★Connect the inlet pipe to the water supply device, and drain the instrument through the water and exhaust.

★ Under the action of no more than 200cm water head, let it stand for a certain time, and then start measuring after the water outlet of the water outlet escapes.

★ During the test, flush the water head pipe to the required height and then close the pipe clamp to start the stopwatch. At the same time, the initial head h1 is measured. After the time t, the test is terminated. The same is the temperature of the test and the water temperature at the end of the test.

★ Calculate the permeability coefficient (change head) according to the formula;

KT=2.3log

Where: a----variable head pipe cross-sectional area, square centimeter

L----diameter, equal to the height of the sample. cm

H1----starting head, centimeter

H2-----water head at the end, cm


土壤渗透仪注意事项:

★上盖出水管处橡胶管不易套至根部 ,须留出6mm以上,以防与套筒受压,

★每次用完应擦净晾干,密封圈宜抹以滑石粉保存。

★切土环刀应妥善保管,防止刃口碰损

Soil penetrant notes:

★The rubber tube of the upper cover water pipe is not easy to be put to the root, and it must be set more than 6mm to prevent the sleeve from being pressed.

★ Every time you run out, you should wipe it dry, and the seal should be stored with talcum powder.

★The earth cutting ring knife should be kept safely to prevent the blade from being damaged.
