9. the sampling method of portable shallow layer soft soil original state sampling device described in claim 1, comprises the following steps:
A. place treatment:According to experimental study object and the requirement of soil test sample, choose suitable area and be sampled, choose ground
Gesture is flat, uniform soil quality position, the miscellaneous soil of desurfacing, smooth exposure ground.The slightly deep soil sample of buried depth need to be such as taken, then needs to combine fiber crops
Flower brills, Luoyang Spade etc. are removed and go up overburden layer, then it is smooth go out to show up, it is flat to use physical features of showing up, and conveniently fetches earth;
B. device prepares:Locator is set up, when the air bubble of transverse and longitudinal spirit bubble is respectively positioned on liquid level to be hit exactly, illustrates horizontal stand
Level, long pin is driven underground by stent foot piece spacing hole, keeps horizontal stand level and position to fix, and assembles sampler,
Insertion latch, vaseline is smeared by liner inside pipe wall, loads sampler barrel, and overlying hollow plastic sheet connects sampler barrel and force-transmitting seat
Fixation is connect, sampler is inserted into horizontal stand spacing hole;
C. it is pressed into soil layer:Uniformly exerted a force by handle, sampler is slowly and steadily pressed into the soil body, it should be noted that both sides force is equal
It is even, can judge whether fall rate is consistent for sampler both sides by the scale of sampler barrel both sides, it is ensured that sampler slowly uniformly sinks
To the expected depth that fetches earth;
D. water is had during sampler is pushed gentle by steam vent discharge, as sampler steps into soil layer, sampler
Internal cavities are gradually decreased, and the pressure produced in cavity is also discharged by steam vent, after the soil body is full of in internal lining pipe, upper extraction sample
Bar, drives steering base and piston to move upwards simultaneously, and piston upper surface is brought into close contact with force-transmitting seat inner chamber upper wall just, closing row
Stomata, while the catch covering steam vent of force-transmitting seat outer surface, also functions to completely cut off the effect of air, so as in force-transmitting seat inner chamber shape
Into vacuum, ensure that the soil sample in sampler does not fall off using negative pressure castering action;
E. exerted a force upwards by handle, sampler is slowly steadily extracted.If frictional resistance is excessive, by steering base rotating band
Dynamic force-transmitting seat and sampler barrel, in rotary manner screw out sampler, and should try one's best guarantee uniform force application, make sampler slowly steady
Rising, until completely from soil extract;
F. the sampler of taking-up is kept flat, pulls down sampler barrel, the roach on hollow plastic sheet is cleared up dry with scraper first
Only, the roach under latch is suitably cleared up, is careful not to disturb the soil sample in internal lining pipe;
G. soil sample is separated:Sampler barrel is passed through into support ring, is screwed and is connected in the fixed cylinder of separator, take out latch, shake hand
Rocking handle, screw rod drives ejector dozer constantly to advance to inside sampler barrel, by the undisturbed in internal lining pipe and internal lining pipe gradually from sampling
The necking section of cylinder is released, because internal lining pipe is half-open lucite tube, in order to prevent internal lining pipe after sampler barrel is deviate from because losing
Constraint open, should internal lining pipe just from necking section exposure when, remaining soil is scraped off along internal lining pipe bottom with fret saw so that soil sample face with
Internal lining pipe bottom port is concordant, adds a cover internal lining pipe lower cover, after internal lining pipe is completely out, scrapes off soil more than internal lining pipe top, adds a cover
Covered on internal lining pipe, because internal lining pipe is that, transparent with machine glass tube, can observe whether taken weak soil meets the requirements, if liner
Soil sample soil property is uneven in pipe or has a large amount of missings, then should refetch;If soil sample is uniformly intact in internal lining pipe, by internal lining pipe top
Label is posted with bottom, is properly sealed up for safekeeping;
H. the remaining soil in sampler barrel inside is removed, internal lining pipe is separately taken, inwall applies vaseline, loads sampler barrel, by sampler barrel and force-transmitting seat
It is connected, continues to sample;
I. after sampling reaches requirement, sampler is dismantled, after pulling down baffle plate, force-transmitting seat can be separated with thief rod, cleaning is passed
Inner chamber and the outer wall of power seat and sampler barrel, dry, and oiling at the screw of sampler barrel latch properly preserves each device.
