Background technology
Ground sampling analysis is essential step before various engineering constructions, is mainly sampled by certain ground
Undisturbed soil soil is tested as sample to understand its base's property by device extraction lower floor.At present, traditional sampler is using
During be primarily present use complicated, bulky, inconvenient to carry, production cost is high, follow-up maintenance is of high cost；No
It can accurately learn depth selection；Multilayer sampling can not once be completed；The problems such as depth selection is limited.In addition, when ground samples,
For Deep Rock soil, since it is more thick and solid hard, sampling is extremely inconvenient.
Utility model content
The purpose of this utility model is exactly to provide a kind of geotechnical stratified to overcome the problems of the above-mentioned prior art
Sampler.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of geotechnical stratified sampler, including supporting rack, cylinder, Stratified Sampling cylinder bar and drill bit, the layering takes
One end of sample cylinder bar connects the piston rod of the cylinder, and the drill bit, the Stratified Sampling cylinder bar are installed on the other end
Upper axially spaced equipped with multiple sampling sections, each sample respectively is equipped with the sample tap of multiple openings obliquely in section, described
Stratified Sampling cylinder bar it is hollow with drill bit internal and connect to form gas passage, be additionally provided with and be used in the Stratified Sampling cylinder bar
The air inlet of the external feeder of connection is additionally provided on drill bit and is connected with gas passage and to the fumarole of side jet.
Preferably, the maximum gauge of the drill bit is more than the outer diameter of sample tap.
Preferably, the graduation mark of record sampling ground depth is additionally provided on the axial direction of the Stratified Sampling cylinder bar.
Preferably, the upper end of the Stratified Sampling cylinder bar is fixed by the piston rod of spline structure and the cylinder, under
End is fixed by helicitic texture and drill bit cooperation.
Preferably, the drill bit includes integrally formed connecting portion and bore portion, wherein, the connecting portion is used to fix
The Stratified Sampling cylinder bar is connected, is distributed in the bore portion and multiple to side jet and connects the fumarole of gas passage.
It is furthermore preferred that the fumarole is also processed into flared expanding outward.
Compared with prior art, the utility model has the following advantages：
(1) Stratified Sampling can be achieved：Since the ground of different layers might have different characteristics, in practice of construction, often
The ground sampling analysis to different depth is needed, multiple sampling sections have been positioned apart from the Stratified Sampling cylinder bar of the present apparatus, have been made
The spacing distance of used time sampling section can be arranged as required to, so as to disposably realize the sampling of DIFFERENT SOIL layer；
(2) depth selection is accurately learnt：Graduation mark is provided on the outer surface of Stratified Sampling cylinder bar in the present apparatus, convenient for standard
Really obtain the depth that each Stratified Sampling cylinder bar gos deep into soil layer.
(3) setting of fumarole can discharge compressed gas to rock-soil layer simultaneously in bit bore on drill bit, in this way, gas
Cognition is stretched into the gap of rock-soil layer, and gap is expanded, and air pressure splitting phenomena is generated, so that soil is soft, convenient for upper
The sampling assemble sampling in portion.
