Abstract
The invention discloses a sampling method for original state sandy soil. The method comprises the following steps: assembling a force applicator, a sampling sleeve and a soil taking cutting edge; for the sandy soil to be sampled, cleaning a soil layer covered above the sandy soil; carrying out freezing treatment on a sandy oil area to be sampled to solidify sandy oil in the area; pressing a sampling device for the sandy soil into the soil layer through the force applicator until the whole sampling device is full of a soil sample; clearing a soil body around the sampling device for the sandy soil, and forming an annular empty slot around the sampling device; slightly shaking the sampling device for the sandy soil to separate the sandy soil on the bottom end of the sampling device from the sampling device, and taking the sampling device out of the soil body; disassembling the force applicator, removing the residual soil body on the top end of the sampling sleeve, and installing an upper sealing cover; and disassembling the soil taking cutting edge, removing the residual soil body on the bottom end of the sampling sleeve, and installing a lower sealing cover. The method has the advantages that sampled sandy soil is less disturbed and is unlikely to become loose, and the original state sandy soil can be conveniently sampled, packaged, transported and transferred.
Description
Technical field
The invention belongs to ground exploration engineering field, and in particular to a kind of sandy soil sampling method and its sampler.
Background technology
With the continuous development of the industry large-scale construction projects such as building, municipal administration, traffic, survey and design level has obtained very big
Improve, the requirement to taking soil body sample is also improved therewith.At present for the sampling soil body, often require which maintains the original state.But
The three-phase system that the soil body is made up of solid matter, water and gas, soil structures are comparatively loose, particularly with sandy soil,
As cohesive strength is very little, in sampling operation, specimen enclosure, storage, transportation, easily disturbance destroys its original structure body
System, causes soil body original state sampling difficult, or even sampling failure.
The Chinese patent of Publication No. CN105547743A discloses a kind of original state soil body sampler and sampling method.
But for sandy soil, as its cohesive strength is very little, being sampled using the apparatus and method can be very big to soil sample generation
Disturbance, acquired soil sample can not represent the primary characteristic of sample section soil.Therefore, it is necessary to be optimized on this basis
Improve.Present applicant proposes a kind of original state sandy soil sampling method and its sampler for being suitable for sandy soil sampling.
The content of the invention
To overcome the above-mentioned deficiency of prior art, the present invention to provide a kind of little to sampling sandy soil disturbance, do not easily cause and take
Sample sandy soil is loose, is easy to the sampling of original state sandy soil, encapsulation, transport, the original state sandy soil sampling method of transfer and its sampling dress
Put.
In order to solve above-mentioned technical problem, the present invention adopts following technical scheme：
A kind of original state sandy soil sampling method, it is characterised in that comprise the following steps：
（1）By applicator, sample sleeve, the cutting edge that fetches earth and fit together；
（2）For sandy soil to be sampled, the soil layer covered above which is first cleaned out, cleaning area is not less than
Area to be sampled, the soil layer covered above sandy soil are different according to geology difference；
（3）Sandy soil region to be sampled is carried out into frost process, after sandy soil reaches frost, just by the sand in the region
Property soil is freezing together, and to reach the function of " shaping ", so during subsequent samples sandy soil can be avoided to be disturbed and become
Shape, can keep the original state of soil sample well；
（4）After region to be sampled reaches frost requirement, by the cutting edge that fetches earth of the sandy soil sampler for assembling
Region to be sampled is placed in, operating personnel are exerted a force by applicator, and sandy soil sampler is pressed into soil layer lentamente
In, whole sampler, i.e. soil sample top surface are filled up until soil sample reach the height same with sandy soil sampler top surface；
（5）The soil body around sandy soil sampler is removed, depth is removed total more than or equal to sampler
Depth so that the dead slot of annular is formed around sandy soil sampler；
（6）Lightly rock sandy soil sampler, make the sandy soil of sandy soil sampler bottom be easier to it is destroyed so as to
Depart from sandy soil sampler, now just sandy soil sampler can be taken out from the soil body；
（7）Applicator is pulled down, then removes the unnecessary soil body in sampling sleeve top, the unnecessary soil body was located in applicator originally,
Then seal closure is installed on the top of sampling sleeve；
（8）The cutting edge that fetches earth is pulled down, then removes the unnecessary soil body of sampling sleeve bottom end, the unnecessary soil body was located at the cutting edge that fetches earth originally
It is interior, lower sealing lid is installed in the bottom of sampling sleeve then, whole sampling process is completed.
In step（3）In, freezing the method for processing is, frost pipe is imbedded in pending stratum, and frost pipe is enclosed
A circle is formed around sandy soil region to be sampled, freezing liquid is input in frost pipe, with by this grittiness surrounded by frost pipe
Native region frost shaping；
The paliform of the frost pipe arrangement squarely broken pipe connection, improves and soil to be sampled while forming certain altitude
Contact area.
Further, step（3）After beginning, in step（4）Before, also comprise the steps：After frost comes into effect, note
The surrounding soil in region to be sampled is protected, interference is produced with the sandy soil for reducing its region to being sampled as far as possible.
Further, in step（7）In, the unnecessary soil body in sampling sleeve top is rooted out using perching knife；In step（8）In, make
The unnecessary soil body of sampling sleeve bottom end is rooted out with perching knife.
Implement a kind of original state sandy soil sampler of above-mentioned sampling method, including frost pipe, applicator, sample sleeve,
