Preferably, described Stratified Sampling cylinder bar is antirust Stratified Sampling cylinder bar.

This utility model has the advantage that

1, Stratified Sampling can be realized: owing to the ground of different layers there may be different characteristics, in practice of construction, generally require the ground sample analysis to different depth, the Stratified Sampling cylinder bar of this device has been positioned apart from multiple sampling section, the spacing distance sampling section during use can be arranged as required to, thus the sampling of DIFFERENT SOIL layer can disposable be realized；

2, depth selection is accurately learnt: this device is provided with graduation mark on the outer surface of Stratified Sampling cylinder bar, it is simple to accurately obtain each Stratified Sampling cylinder bar and go deep into the degree of depth of soil layer；

3, simple in construction, compact, production cost is low, sampling timer stability is high: in the sampler related at present, cylinder is arranged on the bottom of bracing frame, and owing to sampler itself is higher, if cylinder being arranged on the bottom of bracing frame, the height of supporting leg will certainly be increased, make device volume big on the one hand, inconvenient to carry；On the other hand, center of gravity is too high, unstable during use, and particularly when complicated terrain sampling, stability can be worse；And cylinder has been arranged on the top of gripper shoe by this utility model, same depth selection, it is possible to reduce the height of supporting leg so that apparatus structure is compact, stability improves；Additionally, the number of supporting leg is set to three, increase the stability that device is placed further；

4, can sampling in hard soil layer: be connected by cross key between Stratified Sampling cylinder bar upper end and piston rod in this device, torque resistant is big, and drill bit is fluted drill, bores soil rock breaking capacity strong, can stretch into the sampling of hard soil layer depth；

5, follow-up maintenance cost is low: the drill bit in this device is detachably arranged in the lower end of Stratified Sampling cylinder bar, after long-time use is impaired, can be continuing with by more bit change.

6, sampling reliability is high: the Stratified Sampling cylinder bar of this device is antirust Stratified Sampling cylinder bar, it is prevented that mix sampling soil owing to Stratified Sampling cylinder bar gets rusty, and affects its true and reliable property analyzing result.
