Description
Technical field
The utility model relates to geological drilling technology field more particularly to a kind of geology brills for weak soil drill hole sampling
Equipment.
Background technique
Probing refers to be drilled in the earth formation with drilling machine, to identify and divide surface lower stratum, and can be sampled along hole depth
A kind of exploitation method.Probing is a kind of exploration means being most widely used in engineering geological investigation, it can obtain deep layer
Geologic information.It drills as exploration means most mature at present, is widely used in domestic and international all kinds of engineerings, and drill work
For the technological means for most intuitively disclosing the soil layer that crouches under deep layer, it is incorporated into China's codes and standards.Drilling technique is also with domestic basis
The quickening of Facilities Construction, no matter obtained significant progress has from drilling technique, drilling equipment and probing precision etc.
Very big development and progress.And in recent years, drilling technique is fast-developing, all kinds of topographic and geologic conditions are gradually adapted to, even
Rivers, Hu Bo, it can be carried out drilling on ocean, drilling depth hundreds to thousands rice differs.
During all kinds of engineering practices, drilling tool is constantly improved and is updated, and is allowed to adapt to different terrain, different soil
Drilling and sampling.Traditional Sampling driller is mostly universal, and in drilling process, operator is to save the time, accelerates drilling
Efficiency is carried out boring deep and sampling with a kind of drilling tool.In hard soil layer, this method is relatively reasonable, but in soft layer,
When soft layer buried depth is deeper, in drilling and drilling process and when removing soil sample, inevitably weak soil is disturbed.Such as adopt
With traditional drilling tool, when sampling in soft-plastic state clay, brill is mentioned from deep layer, during drilling tool lifting, due to originals such as mechanical shakings
Cause inevitably makes to generate relative displacement between soil sample and drilling tool side wall.Drilling tool is mentioned to ground, is mostly used the methods of to beat, shake and be divided
From soil sample, during beaing, relative displacement can be also generated, and vibration is easy to cause soil sample bleed, influences final testing result.Most
The soil sample obtained eventually can be elongated compared with original soil sample, and diameter becomes smaller, and moisture content also will receive influence.
Utility model content
The technical problems to be solved in the utility model is in view of the drawbacks of the prior art, to provide a kind of for weak soil probing
More convenient, deep layer sample faster, sampling process to undisturbed soil sample disturb it is smaller, can prevent soil sample from falling, sampling process more
Accurately, make the weak soil Sampling driller of the more accurate end card formula of test result.
In order to solve the above technical problems, the utility model adopts the following technical solution: a kind of weak soil of end card formula
Sampling driller is connected and fixed with drilling rod, includes drilling tool pipe, it is characterised in that: the top in drilling tool pipe is provided with one can

From.When being full of soil sample in drilling tool, at this moment no longer drilling depth when drilling lifts drilling tool, active card generates soil sample and encircles bracketing
Effect, does not fall out soil sample, can all take out.The anti-water piston being locked and fastened in hole is finally pushed using tools such as push rods,
Buckle bolt is set to be ejected the hole that is locked and fastened, due to the thrust of spring, piston attachment base, piston, wirerope and piston card are each
It finally resets, can smoothly take out complete soil sample.
The utility model is by drilling tool inner piston, clamping mechanism, drawstring and active card, after soil sample is full of drilling tool,
Since the backstop of clamping mechanism can make drilling tool drilling depth stop drilling.Active card is synchronized by drawstring simultaneously draws high and soil layer is truncated,
And soil layer can be held, so that soil sample is not fallen out during drilling tool lifting.In this way when carrying out weak soil sampling, both can be reduced because
Sampling operation is repeated caused by soil sample is discontinuous, and can drill through more complete weak soil sample, reduces mechanically actuated and soil sample is made
At disturbance increase test accuracy.Workload can substantially be reduced, and reduce the disturbance in conventional method to original state weakness soil sample, because
And weak soil is sampled extremely effective.
