Abstract
The utility model discloses an integrated visual sample preparation instrument for a soft clay hollow cylindrical sample. The integrated visual sample preparation instrument comprises a computer (1), an undisturbed soft clay hollow sample preparation instrument (2), a protective cylinder (3) and a camera (4), wherein the protective cylinder (3) is arranged under the undisturbed soft clay hollow sample preparation instrument (2); the camera (4) is arranged under the protective cylinder (3); one end of the camera (4) is connected with the computer (1). According to the utility model, the integrated visual sample preparation instrument has the following benefits: a coring tool integrally used by the protective cylinder and the camera can effectively cut a core, so that soil crumb can be prevented from being stuck on the wall of a hole and the disturbance and soil-squeezing influence on soil is small during the coring process, and the requirement for undisturbed sample research can be met.
Description
Technical field
The utility model relates to a kind of integrated visual soft clay hollow cylinder specimen sampling instrument that is applicable to soil sample cutting and extracts.
Background technology
At present, the experimental study of carrying out for original hollow cylinder soil sample is both at home and abroad less, mainly contain with (1990) such as Talesnick as representing electric osmose formula and with Britain's Imperial College of Science and Technology (Nishimura for the preparation method of undisturbed sample, 2005, Fig. 1), Zhejiang University (Shen Yang, 2007; Zhang Jinliang, 2007) be two kinds of the mechanical types of representative.
Britain's Imperial College of Science and Technology method is utilized 7 brill cuttves that diameter is different, successively sample is got to core from small to large, reaches the requirement of the hollow internal diameter of design by gradual correction.Its sample preparation has following deficiency: substep drilling rod is got core, make sample after aperture is got core for the first time, just lost can contraposition the hole heart, the vertical thrust that easily causes cannot keeping getting core face, easily hole partially; Substep repeatedly hole forming method has increased the frequency to sample disturbance; Because the stickiness of soft clay is larger, the hole core soil bits that are cut can not come off under Action of Gravity Field, but secondary attaches to inwall, adheres to obstruction boring carry out with hole wall soil.Once soil-cutter adheres to native hole wall and carries out operation still remaining, it is integral that soil bits and hole wall soil will be disturbed, and sample will be subject to very large disturbance, even destruction.Shen Yang (2007), Zhang Jinliang (2007) have been developed the hollow sampling instrument of novel intact soft clay for the physical mechanics feature of Xiaoshan, Zhejiang saturated soft clay, have overcome the deficiency of Britain's Imperial College of Science and Technology mechanical type sample preparation method.But their instrument cannot be observed the concrete condition of inside in the time cutting sample in the time of operation, cannot grasp the real-time information of sample in cutting.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of being made into one sampling instrument that can be used in original soft clay hollow cylinder sample.
Technical characteristics of the present utility model is: be made up of computer, the hollow sampling instrument of intact soft clay, casing, camera, the hollow sampling instrument of its intact soft clay below arranges a casing, casing below arranges a camera, and one end of its camera is connected with computer.
The beneficial effects of the utility model are: the coring tool that casing and camera are combined with, can effectively cut core, and prevent that soil bits and hole wall from sticking, and it is little on the raw disturbance of local products, soil compaction impact to get core process, can meet undisturbed research requirement.
Brief description of the drawings:
Fig. 1 is the utility model product structure schematic diagram
Embodiment:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail
Integrated visual soft clay hollow cylinder sample manufacture instrument, formed by computer 1, the hollow sampling instrument 2 of intact soft clay, casing 3, camera 4, the hollow sampling instrument of its intact soft clay 2 belows arrange a casing 3, and casing 3 belows arrange a camera 4, and one end of its camera 4 is connected with computer 1.
Because soft clay has soil bits and the not segregative situation of inwall, therefore be equipped with specially camera 4 here, moment is noted the whereabouts situation of soil bits, in the time that soil bits are adhered with sample inwall, exit in time drill bit, band is unearthed and considers to be worth doing, in the time of refine sample inwall, can understand in time the smooth degree of inwall by computer 1.
The coring tool that casing 3 and camera 4 are combined with, can effectively cut core, prevent that soil bits from sticking with hole wall, and it is little on the raw disturbance of local products, soil compaction impact to get core process, can meet undisturbed research requirement, visual hollow cylinder specimen sampling instrument provides guarantee for intact soft clay carries out hollow cylinder test.
Claims (1)
1. integrated visual soft clay hollow cylinder sample manufacture instrument, it is characterized in that: formed by computer (1), the hollow sampling instrument of intact soft clay (2), casing (3), camera (4), the hollow sampling instrument of its intact soft clay (2) below arranges a casing (3), casing (3) below arranges a camera (4), and one end of its camera (4) is connected with computer (1).
