Technical field
A kind of soil body disintegration experimental provision is the utility model is related to, belongs to building engineering field.
Background technology
Soil body disintegration equipment is used to test the characteristic that cohesive soil is disintegrated in water.Currently, soil body disintegration experiment instrument mainly wraps
Include the composition such as floating drum, web plate, tank（Water breakthrough profit engineering geotechnique's Experimental Standardization SL237-008-1999, railway engineering centrifugal modeling
Specification TB10102-2004）.
Existing apparatus determines disintegration amount using the change in location of floating drum, and keg float is very unstable during shift in position
Fixed, accuracy of reading is also inadequate.And the relation between soil body water absorption and disintegration amount during disintegration is not accounted for.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of soil body disintegration experimental provision.
A kind of soil body is disintegrated experimental provision, includes the support of duoble-layer table top, and described two layers of table top of support respectively puts an electricity
Sub- balance, a lifting rope frame is kept flat on electronic balance below, and the lifting rope that lifting rope frame both ends pass through through table top hangs web plate, institute
State web plate to be used for placing sample, a lifting rope frame is kept flat on electronic balance above, lifting rope frame both ends pass through hanging through table top
Disintegration cylinder in rope suspension, the web plate are suspended in interior disintegration cylinder；
Also include outer disintegration cylinder, for holding disintegration liquid, the interior disintegration cylinder is hung in outer disintegration cylinder.
The present apparatus is changed using balance reading to weigh soil body disintegration situation, stable reading accuracy height；Using double up and down
Balance can measure corresponding water suction plus exclusive inside and outside double disintegration cylinders while each moment soil body disintegration amount is determined
Amount, this is the maximum feature of the present apparatus, it is contemplated that the influence that water absorption is disintegrated to the soil body.
Brief description of the drawings
Fig. 1, the soil body are disintegrated the structural representation of experimental provision.1- supports, 2- electronic balances, 3- lifting rope framves, 4- lifting ropes, 5-
Interior disintegration cylinder, 6- are disintegrated cylinder, 7- web plates, 8- samples outside.
Embodiment
As described in Figure 1, a kind of soil body disintegration experimental provision, the support of duoble-layer table top, described two layers of table top of support are included
An electronic balance is respectively put, a lifting rope frame is kept flat on electronic balance below, lifting rope frame both ends pass through the lifting rope through table top
Web plate is hung, the web plate is used for placing sample, a lifting rope frame is kept flat on electronic balance above, lifting rope frame both ends are by wearing
Disintegration cylinder in the lifting rope suspension of table top is crossed, the web plate is suspended in interior disintegration cylinder；
Also include outer disintegration cylinder, for holding disintegration liquid, the interior disintegration cylinder is hung in outer disintegration cylinder to be soaked by disintegration liquid
Not yet.
Each one inside and outside present apparatus disintegration cylinder；Web plate perforation size is 10mm × 10mm；Electronic balance scale division value 0.001g；
Stent size is 40cm × 40cm × 50cm；Disintegration cylinder is clear glass cylinder, and inner casing size is 20cm × 20cm × 30cm, outer shell
Size is 30cm × 30cm × 35cm.Web plate eyelet, disintegration cylinder and stent size can be adjusted according to actual conditions.
Experiment takes undisturbed soil on request or 61.8mm × 20mm, 61.8mm × 40mm and a diameter of is made in disturbed soil
39.1mm, 61.8mm, 101mm be highly 2-2.5 times of standard geotechnique cylindrical specimens of diameter or size be 5cm × 5cm ×
5cm cuboid sample.Fetched earth for undisturbed soil by triaxial tests standard.The operating procedure when making disturbance soil sample
For：1. choosing a number of Representative soil sample, through air-drying, pulverizing, sieving, moisture content on request carries out water distribution to soil sample；
2. being fitted into after slightly being stood after water distribution in polybag, it is placed in moisturizing cylinder overnight, makes Water Content Tests in Soil Samples uniform；3. before sample preparation, take out
Its moisture content of soil sample repetition measurement, the difference of moisture content of the moisture content of measure with requiring should be less than ± 1%, otherwise need to adjust moisture content
Until meeting the requirements；4. dry density as requested, weighing required soil property amount, empirically 3 layers of height point hits reality, and every layer is hit in fact extremely
It is required that after height, hair is dug on surface, then adds the 2nd layer of earth material again, so continues, until having hit last layer, will hit in sample cylinder
The leveling of sample both ends, take out and claim its quality, sample density difference should be less than 0.02g/cm3。
This experiment disintegration liquid is typically from aseptic deionized water, web plate selection steel wire, when carrying out acidproof, alkaline-resisting etc. collapse
During solution experiment, corresponding disintegration cylinder, web plate and lifting rope are made according to specific disintegration liquid.Experiment starts front opening camera
Alignment disintegration cylinder and electronic balance are imaged, and adjust DOOR HEIGHT and liquid level according to specimen size so that outer shell
Liquid level did not had inner casing just and sample has been disintegrated rear and has been unlikely to be close to web plate, reset balance after regulating, rapidly will examination
Sample is placed on web plate center, starts stopwatch, and surveys the reading of balance when note starts immediately.After experiment starts 1s, 3s, 10s, 30s,
1min, 3min, 10min, 30min, 1h, 2h, 3h, 4h ... survey the reading of note balance, the speed being disintegrated according to sample, can be appropriate
Shorten or increase the time interval estimated until disintegration terminates.After sample is fallen by grid completely, experiment comes to an end.Such as
Fruit sample is not disintegrated for a long time, then records situation of the sample in water, terminate experiment.
