Background technology
In-situ test cone penetration test China apply more than 30 years, it using contact method test soil strength and
Deformation, and set up on the basis of regression relation with various conventional meanses, scene determines every design parameter of the tested soil body and refers to
Mark, such as bearing capacity, modulus of compressibility, state of soil, with probing compare with it is simple, economical, quick the characteristics of, but there is also one
Fixed defect, can not such as identify soil layer color and more difficult accurately name great soil group, decision state, and (pass through for identical mechanical index
Enter impedance value identical), and different types of soil (such as cohesive soil and sandy soil), it is accurate to judge just more difficult.Existing static(al) is touched
Trial and error test is the penetration resistance numerical value that stratum is obtained using sensor, and the title for empirically carrying out soil judges (such as cohesive soil, sand
Property soil), popular name calculates every design parameter of soil layer again after determining, if but cohesive soil and sandy soil penetration resistance numerical value phase
Together, erroneous judgement will be produced, and great soil group is different, design parameter such as bearing capacity, modulus of compressibility etc. differ greatly, and bring hidden to construction project
Suffer from.Judged by accident to reduce, drill sampling hole is increased typically near cone penetration test point, stratum is carried out according to hore plug accurate
Differentiation is named.So then need to carry out cone penetration test, need to carry out soil drill sampling again, troublesome poeration is unfavorable for
The implementation of engineering and progress.

Further, the leaf spring is bolted on cylinder inboard wall.
The beneficial effects of the invention are as follows：The present apparatus, can be while cone penetration test, needed for taking by sample cartridge module
The stratum soil sample wanted, can accurately judge soil layer title, color, state, and carry out distinguishing hierarchy with reference to mechanical index, there is provided each
Item technical parameter, compared with drill sampling, can not only take the soil sample on corresponding stratum, accurately judge soil layer title, color, state
It is etc. the technical indicator that quiet trial and error test can not be provided but also fine and smooth using quiet spy accurate positioning, level, high excellent of data precision
Gesture, it is further provided more meet actual and requirement of engineering the design technical parameter of engineering.Its compact structure, practicality easy to operate,
Do not change feeler lever structure directly to replace and reuse, and installation tune can voluntarily be carried out according to the soil depth of required exploration
It is whole, ground observation operating efficiency is significantly improved, it is appropriate to reduce probing quantity, working time and cost are saved, improve static(al)
The accuracy and efficiency of cone penetration test.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.The specific embodiments described herein are merely illustrative of the present invention, is not used to limit
The fixed present invention.As long as additionally, technical characteristic involved in invention described below each implementation method is each other
Not constituting conflict can just be mutually combined.
As illustrated in fig. 1 and 2, the present invention includes cylinder 1, and cylinder 1 includes setting 2 Hes of threaded cylinder top on excircle
Cylinder body bottom 3, the inner hollow of cylinder 1 is laterally provided with a rectangular mounting hole 5 on its barrel, and the width of mounting hole 5 is less than
The diameter of cylinder 1.Two pin-and-holes 8 are provided with mounting hole 5 in the barrel of cylinder 1, two pin-and-holes 8 are symmetricly set on mounting hole
5 both sides.A sample cartridge module 6 for tubular is fixed with by through the bearing pin eccentric rotary of pin-and-hole 8 in mounting hole 5, in cylinder
