Abstract
The utility model discloses a telescopic overlapped type flexible bag tube core taking inner tube which comprises a core taking support cylinder; the core taking support cylinder is connected with a protecting sleeve; a gap is arranged between the outer wall of one section of the core taking support cylinder and the inner wall of the protecting sleeve; the gap is internally provided with a telescopic folding flexible bag tube; and the end part of the flexible bag tube is connected with a core taking cover. The sample disturbance degree of the flexible bag tube core taking inner tube is less than 5%, and the moisture fidelity of the flexible bag tube core taking inner tube is higher than 95%. The disturbance degree of a rigid core taking tube is more than 30-50%, and the moisture fidelity of the rigid core taking tube is lower than 70-95%. Compared with the rigid tube, the flexible bag tube saves 50-70% of cost; furthermore, the telescopic overlapped type flexible bag tube core taking inner tube is simple in structure and convenient to use.
Description
Technical field
The utility model belongs to engineering geologic investigation, solid mineral exploration, coal seam and combustible ice stratum and reconnoitres device, is specifically related to the coring device that creeps into of a kind of small-bore test core (ore deposit core) and soil sample original state sample.
Background technology
Rigidity such as single tube, two-tube triple pipe corer is the mature technology of small-bore drilling operation, but there is the shortcoming of a maximum in the rigidity corer.The core that is underground taking-up is poured out the volatilization that is disturbed bar none when going packaging applications again with moisture in rigid pipe, have influence on the degree of accuracy and the integrity degree of physical and chemical index chemical examination to some extent.Bigger such as special core influence such as thixotropy mud, frozen soil and combustible ice.
Summary of the invention
The purpose of this utility model is to provide a kind of flexible folded type flexible pouch pipe to get the in-core pipe, to address the above problem.
The technical solution of the utility model is: flexible folded type flexible pouch pipe is got the in-core pipe; it comprises gets the core support tube; get on the core support tube and be connected with protective casing; protective casing and get the outer wall of one section of core support tube and the protective casing inwall between gapped; be provided with folding retractable and flexible bag pipe in the described gap, the end of flexible pouch pipe connects gets core cap.
The described core support tube of getting comprises the connection base section, protective casing linkage section and flexible pouch pipe supporting section; Connect between base section and the protective casing linkage section and establish the spacing end face of protective casing linkage section, be provided with the spacing end face of flexible pouch pipe between protective casing linkage section and the flexible pouch pipe supporting section.
The described core cap of getting comprises flexible pouch tube end retainer ring, the core end limited cover that is connected with flexible pouch tube end retainer ring.
Described flexible pouch tube end is clamped between flexible pouch tube end retainer ring and the core end limited cover.
Described flexible pouch pipe be axially folding or radial folding at protective casing and get in the gap between the core support tube.
The utility model adopts flexible superposed type flexible pouch pipe; it is located at protective casing and gets in the gap between the core support tube; during drill hole sampling; core enters to be got in the core support tube jacking and gets core cap; the flexible pouch pipe stretches out the coating core synchronously one by one forward to be finished until round trip; the flexible pouch pipe is got the sample disturbance degree of in-core pipe less than 5%, and the moisture fidelity is higher than 95%.Rigidity corer disturbance degree is greater than 30-50%, and the moisture fidelity is lower than 70-95%.The about cost 50-70% of flexible pouch pipe specific rigidity tube coupling, it is simple in structure, and is easy to use.
